Did You Know?
Spending more time engaged in real-world activities and reducing screen timeespecially passive use like watching TVhas been linked to improved academic performance and better mental health outcomes in children and adolescents.
Excessive screen exposure, particularly from television and video games, can detract from study time, sleep quality, and focus, all of which are crucial for maintaining a strong grade-point average (GPA). A higher GPA not only
opens doors to better educational opportunities but also lays the foundation for a more stable and successful career. By prioritizing offline experiences like reading, social interaction, and physical activity, students can cultivate
habits that support long-term achievement and well-being.
IQ (Intelligence Quotient) tests are standardized with an average score of 100 and a typical standard deviation of 15, placing about 68% of people
in the 'average' range of 85 to 115. Scores between 90109 are considered average, 110119 as high average, and 120129 as above average or superior. Scores of 130 and above fall into the 'gifted' range, which can be further
categorized as follows: 115129 (above average or bright), 130144 (moderately gifted), 145159 (highly gifted), and 160179 (exceptionally gifted). Roughly 2% of individuals score above 130, while a similar percentage fall
below 70a level often associated with intellectual disability.
Astronomy is the scientific study of celestial objects and phenomena beyond Earth's atmosphere. It encompasses everything from planets, moons, and stars to galaxies, nebulae,
and cosmic events like supernovae and gamma-ray bursts. The field is divided into observational astronomy, which focuses on collecting data from telescopes and instruments,
and theoretical astronomy, which develops models to explain cosmic phenomena. Astronomy is deeply intertwined with both physics and chemistry, as it relies on principles from
these fields to explain celestial phenomena. Physics provides the fundamental laws that govern the universe, helping astronomers understand the behavior of celestial objects
while chemistry plays a vital role in understanding the composition and reactions of celestial bodies.
Physics and chemistry allow astronomers to decode the universe, from the birth of stars to the formation of planets and the evolution of galaxies.
Gravity Newtons and Einsteins theories explain planetary motion, black holes, and galaxy formation.
Electromagnetism Light and radiation from stars are studied using electromagnetic theory.
Thermodynamics Helps explain stellar evolution, nuclear fusion in stars, and the behavior of gases in nebulae.
Quantum Mechanics Essential for understanding atomic interactions in stars and the behavior of subatomic particles in extreme cosmic environments.
Relativity Einsteins theory of relativity is crucial for studying black holes, gravitational waves, and the expansion of the universe.
Spectroscopy Astronomers analyze light from stars and galaxies to determine their chemical composition.
Nuclear Fusion The process that powers stars, where hydrogen atoms fuse into helium, releasing immense energy.
Interstellar Chemistry Studies molecules in space, including organic compounds that may be linked to the origins of life.
Planetary Science Examines the chemical makeup of planets, atmospheres, and potential habitability.
Astronomy has ancient roots, with civilizations like the Egyptians, Babylonians, Greeks, and Chinese making systematic observations of the night sky. Over time, it evolved
from simple star charting to a sophisticated science incorporating physics, chemistry, and mathematics. Today, astronomers use advanced telescopes, space probes, and computational
models to explore the universe's mysteries, including the origins of galaxies and the nature of black holes.
Earth is the third planet from the Sun and the largest of the terrestrial planets, which include Mercury, Venus, Earth, and Mars; Earth is the only known planet to support life.
Name: The name Earth is at least 1,000 years old; all of the planets, except for Earth, were named after Greek and Roman gods and goddesses; however, the name Earth is a Germanic word, which simply means the ground.;
there are, of course, many names for our planet in the thousands of languages spoken by the people of the third planet from the Sun.
Liquid Water: Earth is the only known planet to have liquid water on its surface, which is essential for life.
Age and Formation: Earth formed about 4.54 billion years ago; life appeared around 3.8 billion years ago, and humans have been around for only about 6 million years.
Speedy Traveler: Earth orbits the Sun at an average speed of about 107,182 kilometers per hour (66,627 miles per hour).
Day and Year: A day on Earth is 23.9 hours long, and it takes 365.25 days to complete one orbit around the Sun, which is why we have a leap year every four years.
Tilt and Seasons: Earths axis is tilted at 23.4 degrees, which causes the seasons; as Earth orbits the Sun, different parts of the planet receive varying amounts of sunlight; the rotation of the Earth is gradually slowing down.
Cosmic Dust: Earth receives between 100 and 300 metric tons of cosmic dust every day.
Exploration: Despite being covered by over 70% water, more than 95% of Earths oceans remain unexplored.
Gravity: The gravity between the Earth and the Moon causes the tides on Earth; the Hudson Bay region in Canada has slightly less gravity than other parts of the planet, and the reasons behind this anomaly are unknown.
NASA announced the discovery of 715 new exoplanets orbiting 305 stars outside our solar system, including four planets more than twice the size of Earth, which boosted the total number of confirmed planets in our galaxy to over 1,700.
This milestone was achieved largely through data collected by the Kepler Space Telescope using a method called verification by multiplicity, which allowed researchers to confirm multiple planet candidates within the same star system.
The discovery highlights the diversity and abundance of planetary systems in the Milky Way, reinforcing the idea that multi-planet systems are common and expanding the search for potentially habitable worlds.
A significant number of stars in our galaxy host planets within the habitable zonethe region around a star where conditions may allow for liquid water on a planets surfacemaking the potential for life beyond Earth increasingly plausible.
One notable system, L 98-59, located just 35 light-years away, includes five rocky planets, with L 98-59 f receiving Earth-like energy levels from its star, positioning it firmly within the habitable zone. NASA estimates that about half of
Sun-like stars could harbor rocky, potentially habitable planets, which could amount to hundreds of millions in the Milky Way alone, underscoring the exciting possibility of discovering Earth-like worlds elsewhere in the universe.
The first scientific detection of an exoplanet was in 1988. However, the first confirmed detection came in 1992; since then, and as of 1 April 2017, there have been 3,607 exoplanets discovered in 2,701 planetary systems and 610 multiple planetary systems confirmed.
The Sun is approximately 333,000 times more massive than Earth, but its sheer volume is even more astonishingif it were hollow, it could hold around 1.3 million Earths. With a diameter about 109 times that of Earth, it's by far the
largest object in our solar system, dominating its gravitational landscape.
Sunlight takes a little more than 8 minutes to reach the Earth; this means that when we are looking at the sun as it as 8 minutes ago. Because the Sun is about 93 million miles (150 million kilometers) from Earth and light travels
at a finite speedabout 186,000 miles per second (300,000 km/s)it takes sunlight roughly 8 minutes and 20 seconds to reach us. So when you look at the Sun, you're actually seeing it as it was 8 minutes ago, not in real time. If
the Sun were to suddenly vanish (hypothetically!), we wouldnt notice for over 8 minutes. Its a fascinating reminder that light is a kind of time machine, letting us glimpse the past with every sunrise.
High and low tides on Earth are caused by the gravitational forces of both the Moon and the Sun, with the Moon having the stronger influence due to its proximity. As the Moons gravity pulls ocean water toward it, it creates tidal
bulgesone on the side of Earth facing the Moon and another on the opposite side from inertia. The Suns gravity also plays a role, enhancing tides when it aligns with the Moon during full and new moons to produce spring tides, and
counteracting them during quarter moons to create weaker neap tides. This dynamic interaction between celestial bodies and Earths rotation results in the rhythmic rise and fall of ocean tides.
Due to Mars having only about 38% of Earths gravity, a person who weighs 100 kilograms on Earth would weigh just 38 kilograms on the surface of Mars. This dramatic reduction is a result of Mars being smaller and less massive, with a
surface gravity of approximately 3.72 m/s² compared to Earths 9.81 m/s². The lower gravity would allow for easier movement and higher jumps, but over time, it could also lead to muscle weakening and bone density loss, posing challenges
for long-term human habitation and space exploration.
The Sun has a staggering diameter of about 864,000 miles (1,391,000 kilometers). By comparison, Earth spans 7,926 miles (12,756 kilometers), and the Moon measures a mere 2,159 miles (3,475 kilometers). The scale difference is enormous:
the Sun is roughly 109 times wider than Earth, and Earth is about 3.7 times wider than the Moon. Despite these vast contrasts, the Sun and Moon appear eerily similar in size from our viewpoint on Eartha remarkable alignment created by
the proportions of their distances. This illusion lies at the heart of one of natures most spectacular events: the solar eclipse.
Mercury, the closest and smallest planet in our solar system, orbits the Sun in just 88 Earth days, but takes nearly 176 Earth days to complete a full
sunrise-to-sunset cycle due to its slow rotation. With no substantial atmosphere to trap heat, its surface experiences dramatic temperature swingsfrom scorching highs of about 840°F (450°C) during the day to bone-chilling lows
around -300°F (-185°C) at night. This extreme thermal contrast makes Mercury a world of blazing sunlight and frozen darkness.
Mercurys surface gravity is about 38% that of Earths, making it difficult to retain an atmosphere. Instead, it has a faint exosphere composed of elements like sodium, potassium, calcium, and magnesiumreleased from the surface by solar
wind and micrometeorite impacts. This exosphere is so sparse that Mercury has no wind, no breathable air, and no weather. Surprisingly, though, water ice may exist deep inside permanently shadowed craters at its poles, where frigid conditions
prevent it from evaporating despite the planets extreme daytime heat.
Mercury the innermost and smallest of the terrestrial planets, is indeed the least explored rocky world in our solar system. It formed roughly 4.6 billion
years ago during the chaotic early stages of planetary formation, when dust and gas from the solar nebula clumped together under gravity. Unlike Earth, Mars, or Venus, Mercury has only been visited by two spacecraft: Mariner 10 in
the 1970s and MESSENGER, which orbited the planet from 2011 to 2015. This limited exploration leaves many of its mysterieslike its oversized iron core, dramatic temperature swings, and potential polar icestill largely unsolved.
Compared with our own Moon, which is about the same size, the Mercury planet reflects much less light.
There's a lot more carbon dust thrown off from comets close to the Sun, where Mercury orbits -- about 50 times as much for Mercury as for our moon.
Venus is often called Earths sister planet because the two share remarkable physical similarities: theyre nearly the same in size and mass, and both are rocky planets
with similar internal compositions of iron cores and silicate mantles. However, despite these parallels, Venus has a thick carbon dioxide atmosphere that drives a runaway greenhouse effect, making it the hottest planet in our solar system.
The surface pressure is crushingabout 92 times greater than Earthsand its clouds contain corrosive sulfuric acid. Adding to its strangeness, Venus rotates slowly and in the opposite direction of most planets, with one Venusian day lasting
longer than a year, creating a world thats far more hostile than its terrestrial twin.
Venus is the second planet from the Sun, orbiting it every 224.7 Earth days.
It has almost the Earth size, and is covered in thick clouds that are made mostly of carbon dioxide and acid. The surface temperature can be as high as 930° F, caused mostly by the clouds that trap the heat and reflect it back.
One day on Venus is 243 Earth days, and its year is 225 Earth years.
Earth was formed around 4.54 billion years ago, long before the Common Era, during a period known as the Hadean Eon, when the solar system was still taking shape. Through a process called accretion, dust and gas from the solar nebula
coalesced under gravity to form the young planet. Not long after, a colossal impact with a Mars-sized body named Theia likely led to the formation of the Moon. Over time, Earth cooled, developed a solid crust, and eventually formed
oceanssetting the stage for the emergence of life and the dynamic planet we know today.
Earth is the third planet from the Sun, the densest planet in the Solar System, the largest of the Solar System's four
terrestrial planets, and the only astronomical object known to accommodate life.
Formed about 4.6 billion years ago, the Earth speeds around the Sun in 365 Earth days. The average temperatures on Earth is around 59° F.
Mars is the fourth planet from the Sun and the second smallest planet in the Solar System.
It is a Red Planet and the closest planet to Earth, has polar ice caps, suggesting the water is on Mars. Temperatures on Mars during the day are about 80° F, but at night drop to -270° F.
Jupiter is the fifth planet from the Sun and the largest planet in the Solar System.
It has no surface because it is made mostly of gasses. The average temperature on Jupiter is -235° F. Jupiter has a day that lasts 9.9 Earth hours and a year that lasts 11.9 Earth years.
Saturn is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter.
It is a gas giant planet with no surface to walk on. The average temperature on Saturn is -218° F. One day on Saturn is 10 Earth hours and one year is 29.46 Earth years.
Uranus, has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. It is
a gas giant with no surface to walk on, and is a unique planet with its blue-green color caused by the methane gas that reflects back blue and green light. Only one pole of Uranus faces the Sun, while the other is in complete darkness. One side of Uranus gets 42 years of light, followed by 42 years of darkness.
Uranus has a temperature of -323° F. The average day on Uranus is 17.9 Earth hours and a year is 84 Earth years.
Neptune, which is the eighth and farthest planet from the Sun in the Solar System, has many dwarf planets (i.e.; it isnt large enough to be considered a planet).
On this planet the winds blow over 1,200 miles per hour and the temperature is -350° F. One day on Neptune is equal to 19 Earth hours and one year is equal to 164.8 Earth years.
Leonardo da Vinci was a visionary inventor whose designs foreshadowed modern technology. Although many of his inventions remained theoretical, they demonstrated his deep understanding of engineering and physics.
Leonardo da Vinci's ability to merge creativity with scientific reasoning continues to inspire innovation today.
Ornithopter Inspired by birds, Leonardo da Vinci designed a flying machine with flapping wings, aiming to achieve human flight centuries before airplanes were invented.
Helical Air Screw A precursor to the modern helicopter, this device featured a spiral-shaped rotor intended to lift off vertically.
Parachute Leonardo da Vinci sketched a pyramid-shaped parachute that could allow a person to descend safely from great heights; a modern test proved his design was functional.
Self-Propelled Cart Often considered an early prototype of the automobile, this cart was powered by a system of gears and springs.
Mechanical Knight A humanoid automaton capable of sitting, standing, and moving its arms, making it one of the earliest robotic designs.
Diving Suit Designed for underwater exploration, Leonardo da Vincis diving suit featured breathing tubes and a system to allow divers to stay submerged.
Machine Gun A multi-barreled cannon designed to fire rounds in succession, an early concept of rapid-fire weaponry.

It's quite rare for someone to hold many university degrees, but there are a few notable individuals who have achieved this impressive feat. One such person is Benjamin Bradley Bolger (born 1975) is an American perpetual student
who had earned 16 academic degrees as of March 2022. Dr. Tue Nguyen is an extraordinary individual who earned an impressive seven degrees from MIT; his degrees include bachelor's degrees in physics, computer science and engineering, electrical engineering, mathematics,
and nuclear engineering, as well as a master's degree and a PhD in nuclear engineering. Another example is Luciano Baietti from Italy who holds the Guinness World Record
for the most university degrees, with a total of 15 bachelor's or higher-level degrees, including sociology, literature, and criminology.
Akshay Venkatesh, Erik Demaine, Jennifer Chen, and Rachel Hill are ones of the youngest people to receive doctorate degrees around the world. They have shown exceptional dedication and talent in their respective fields at such young ages.
Akshay Venkatesh - Born in 1981, in New Delhi, India, and moved to Perth, Australia, with his family when he was two years old; at just 20 years old, Akshay Venkatesh earned his PhD in Mathematics from Princeton University in 2002;
he is a mathematician who had already won multiple medals at the International Physics and Mathematics Olympiads by the age of 12. He is currently a professor at the Institute for Advanced Study in Princeton, New Jersey.
Erik Demaine - Erik Demaine, born in 1981 in Canada, completed his PhD in Computer Science at the University of Waterloo at the age of 20 in 2001; he is known for his work in computational origami and became MIT's youngest professor at the age of 20.
He completed his bachelor's degree at Dalhousie University at the age of 14.
Jennifer Chen - Jennifer Chen earned her Doctor of Medicine (MD) degree from Florida International University's Herbert Wertheim College of Medicine in 2015, specializing in radiology, at the age of 24; she is a Lead Breast Imager and
Assistant Clinical Professor at City of Hope Orange County. She skipped high school and entered college early, earning her bachelor's degree in biology at 18.
Rachel Hill - Rachel Hill graduated from Manchester Medical School at the age of 21 in 2010, making her one of the youngest doctors in the UK; she was accepted into medical school at 15 due to her outstanding academic performance, and
started at the University for her medicine study just a few weeks after her 17th birthday.
Buckingham Palace, originally built in 1703 and now serving as the official residence and administrative headquarters of the British monarch, is estimated to be worth around $1.6 billion. The sprawling London estate boasts 775 rooms,
including 78 bathrooms, 19 staterooms, and a vast garden that holds the title of largest private garden in London. Though it's not privately owned by the royal familyits held in trust by the Crown Estatethe palace remains a symbol of
British heritage and monarchy, hosting state events, royal ceremonies, and thousands of visitors each year.
Elizabeth Blackwell (1821-1910) was the first woman physician in the U.S. She received her medical degree in 1849 from Geneva Medical College in New York.
The University of Pennsylvania School of Medicine (former College of Philadelphia Department of Medicine), which was established on May 3, 1765, was the first medical college in the U.S.
The first commencement was held June 21, 1768, when medical diplomas were presented to ten members of graduating class.
Ludwig van Beethoven (1770 1827), a German composer and pianist, is the most admired composers in the history of Western music.
Beethoven's works rank amongst the most performed of the classical music repertoire and span the transition from the Classical period to the Romantic era in classical music. Many of the pieces that
he wrote are still recognized today and even used in contemporary musical compositions. Most remarkable about his career is that the infamous musician was
completely deaf while continually played his music.
One of Beethovens best-known works among modern audiences,
Symphony No. 5 is known for its ominous first four notes. His ninth and final symphony,
completed in 1824, is the most famous piece of music in history.
Confucius (551 - 479 BCE) is Chinas most famous teacher, philosopher, and political theorist, whose ideas have profoundly
influenced the civilizations of China and other East Asian countries. His philosophical teachings, called Confucianism, emphasized
personal and governmental morality, correctness of social relationships, justice, kindness, and sincerity. Confucianism was part of the Chinese social fabric and way of life; to Confucians, everyday
life was the arena of religion.
Samuel Adams (1722 1803), a graduate of Harvard College, was an American statesman, political philosopher, and a Founding Father of the United States.
He was a leader of the American Revolution, and one of the architects of the principles of American republicanism that shaped the political culture of the United States;
he served as Governor of Massachusetts in 1794. Before becoming a well-known politian Adams was an unsuccessful businessman and tax collector, who often failed to collect taxes from his fellow citizens; and he has also often been described as a brewer, but actually he worked as a maltster and not a brewer.
After his death in 1803 the Boston Beer Company used Samuel Adams's name for creating the Samuel Adams Boston Lager, which became a popular award-winning brand.
William Holmes McGuffey (1800 1873), a U. S. educator and clergyman,
is remembered chiefly for his series of illustrated readers for elementary school, and is best known for writing the
McGuffey Readers, the first widely used series of elementary school-level
textbooks that educated millions of Americans. Mr. McGuffey helped to organize the public school system of Ohio, and served as the president
of the Woodward Free Grammar School in Cincinnati, OH, one of the earliest public schools in the U.S.
More than 120 million copies of McGuffey Readers were sold between 1836 and 1960.
He was very fond of teaching children as he geared the books toward a younger audience. McGuffey's Readers, which was graded collections of didactic tales and excerpts from great books, reflecting
his view that the proper education of young people required their introduction to a wide variety of topics and practical matters, could guide children from learning the alphabet all the way to
high school materials, as each volume increased in skill level; they became standard texts in nearly all states in the U.S. since 1836.
Frederick Douglass was born into slavery in Maryland, 1818. At that time, Black children were not allowed to attend school,
but he understood the power and value of literacy, so, at a young age, he taught himself to read and write. He educated himself on the rights of freedom; after several unsuccessful attempts to escape slavery,
he finally managed to escape when he was 20-year old. Douglass was an excellent writer and wrote several books. He was a firm believer in the equality of all peoples, white, black, female, Native American, and
Chinese immigrants. He traveled throughout the northern and midwestern states, speaking on behalf of the anti-slavery movement. He successfully fought for the 13th Amendment (which abolished slavery),
the 14th Amendment (which granted citizenship to those born in the United States as enslaved persons) and the 15th Amendment (which granted voting rights to men of all color women would not gain the right to vote until
the 19th Amendment in 1920).
The longest one-syllable words in the English language are "scraunched" and "strengthed" (10 letters). Some suggest that "squirreled" could be included, but squirrel is intended to be pronounced as two syllables (squir-rel) according to most dictionaries.
"Screeched" and "strengths" are two other long one-syllable words, but they only have 9 letters.
"Stewardesses" is the longest word that is typed with only the left hand. On a standard QWERTY keyboard, the word stewardesses stands out as the longest commonly used English word that can be typed entirely with the left hand,
using only keys from the left side such as S, T, E, W, A, R, and D. While there are longer and more obscure contenders like aftercataracts or tesseradecades, stewardesses remains the most recognized and accessible example of
left-hand-only typingmaking it a favorite in keyboard trivia circles.
Dous is a rare word ending in English, and only a handful of words using it are commonly recognized. The four most familiar are tremendous, horrendous, stupendous, and hazardous, all of which are adjectives describing intensity or danger.
Beyond these, there are dozens of obscure or technical terms like apodous (lacking feet), iodous (relating to iodine), macropodous (having large feet), and vanadous (pertaining to vanadium), most of which appear in scientific or specialized contexts.
In total, there are around 60 to 80 words ending in dous, but the vast majority are rarely used outside of academic or niche fields.
Dreamt is the only common English word that ends in the letters mt, with other rare forms like daydreamt and undreamt sharing this unique ending. Both dreamed and dreamt serve as correct past tense forms of dream, but regional
preferences differ: dreamt is more common in British English, while dreamed is favored in American English and other English-speaking regions. With roots dating back to the 14th century, dreamt has been used by literary figures like
Shakespeare and Jane Austen, adding historical depth to this quirky linguistic fact.
There are exactly 293 distinct ways to make change for one dollar using U.S. coins, including combinations of pennies (1’), nickels (5’), dimes (10’), quarters (25’), half-dollars (50’), and dollar coins. These variations range
from straightforward options like four quarters or 100 pennies to more complex mixes like one half-dollar, two quarters, five nickels, and 25 pennies. The calculation of these combinations involves principles of combinatorics and
integer partitioning, making it a surprisingly intricate problem rooted in everyday currency.
A U.S. dime has 118 tiny grooves, known as ridges or reeds, etched around its edgea design originally intended to prevent coin shaving when dimes were made of silver. Back then, people would scrape off small amounts of metal,
so the ridges made tampering easy to detect. Although modern dimes are no longer silver, the ridges remain as a nod to history and as a tactile aid for the visually impaired to help distinguish between coins.
While many believe people fall asleep in exactly 7 minutes, the reality is a bit more nuanced. The average sleep onset latency for healthy adults is usually between 10 to 20 minutes, though this can vary based on factors like stress,
caffeine intake, and sleep disorders. Some individuals may drift off faster, especially when sleep-deprived, while others may take longer. Consistently falling asleep in under 5 minutes might indicate sleep deprivation, whereas needing
more than 30 minutes could suggest insomnia or other sleep-related issues.
Like fingerprints, each person has a unique tongue print defined by its shape, texture, and surface grooves, making it a potential tool for biometric identification. The tongue plays a vital role in everyday functions: it helps
mix and move food during chewing, contains lingual tonsils that filter out germs and support immune defense, shapes sounds to form words during speech, and even assists in swallowing by pushing saliva down the throat while we sleep.
Hidden inside the mouth, the tongues protected location helps preserve its distinctive features, further contributing to its reliability as a biological identifier.
After a meal, food typically spends 6 to 8 hours moving through the stomach and small intestine, where most digestion and nutrient absorption occur. It then enters the large intestine (colon), where water and remaining nutrients are
absorbed and the waste is compacted into stool. On average, it takes about 36 hours for food to travel through the colon before elimination, though this can vary based on factors like diet, age, gender, and activity level. The entire
digestive processfrom eating to excretioncan range from 24 to 72 hours depending on the individual.
At birth, a baby has around 300 bones, many of which are made of cartilage to allow flexibility during childbirth and early growth. As the child matures, many of these bones gradually fuse together, especially in areas like the skull,
spine, and limbs. This fusion process continues through childhood and adolescence, eventually resulting in the 206 bones that make up the adult human skeleton.
The right side of our body is controlled by the left side of our brain while the left side of our body is controlled by the right side of our brain. Each side of the human brain controls the opposite side of the body in a phenomenon
known as contralateral control: the left hemisphere governs movement and sensation on the right side, while the right hemisphere controls the left side. This crossover occurs because motor and sensory nerves cross over in the brainstem
before reaching the body, explaining why conditions like strokes can affect the limb or function opposite the damaged brain region.
Antibiotics, which are medications that destroy or slow down the growth of bacteria, are only effective against bacteria, they won't help in fighting off a virus, and cannot treat viral infections, such as cold,
flu, and most coughs.
Antibiotics are medications that either kill bacteria or inhibit their growth, making them effective only against bacterial infectionsnot viral onesso they wont help treat illnesses like the common cold, flu, or most coughs.
Misusing antibiotics for viral infections not only fails to cure the issue but also increases the risk of antibiotic resistance, which can make future bacterial infections harder to treat.
Fruits like apples, pears, summer squashes, and bananas float in water because their porous, relatively dry flesh contains a significant amount of airapproximately 25% of their volumewhich reduces their overall density and
allows them to stay buoyant. This air is trapped in the intercellular spaces of the fruit, creating a natural floatation effect that's not shared by denser fruits like grapes or avocados.
The worlds youngest university graduate was a 9-year-old Belgian student Laurent Simons.
After completing high school in roughly a year, Laurent born in Belgium but now living in the Netherlands started college and finished the three-year bachelors program in electrical engineering from Eindhoven University of Technology in the Netherlands in just nine months in early 2020.
The youngest person to obtain a college degree is American Michael Kearney, who achieved the feat in June 1994 at the age of 10 years 4 months.
In the U.S. parents could mail their kids to any place using the U.S. postal service until 1914.
The first known case of a mailed baby was in 1913 when a couple in Ohio used the postal service to ship their 10-pound infant son to his grandmothers home about a mile away, paying 15 cents in postage and springing for $50 in insurance (optional); however,
records do not indicate whether his grandmother received her mail in a mailbox or through a letter slot. Some children were mailed much farther, hundreds of miles away, with the appropriate stamps stuck to their clothes.
Vegetarians follow a plant-based diet that excludes all forms of meat, poultry, fish, and seafood, focusing instead on foods like vegetables, fruits, grains, legumes, soy products, nuts, and seeds. In contrast, demi-vegetarians or
semi-vegetarians adopt a more flexible approach: while they avoid red meat, they still consume poultry, fish, or other seafood. These dietary patterns fall along a spectrum of plant-forward eating, with vegetarians maintaining stricter
boundaries and demi-vegetarians blending plant-based choices with select animal proteins.
As of 2025, the top paid video streaming services in the U.S. include Netflix, Amazon Prime Video, Disney+, Max (formerly HBO Max), Hulu, Apple TV+, Paramount+, and Peacock, which dominate the subscription-based streaming market.
These platforms offer a mix of original content, blockbuster movies, live sports, and network TV shows. Traditional providers like Comcast/Xfinity, DirecTV, Spectrum/Charter, Dish, Fios Verizon, Altice, and Cox still offer streaming bundles
or on-demand services, but theyre increasingly being supplementedor replacedby standalone apps and cord-cutting options.
A shrimps heart is in its head; a crocodile cannot stick its tongue out; tigers have striped skin, not just striped fur;
the giant squid has the largest eyes in the world; an ostrich's eye is bigger than its brain; shark is the only known fish that can blink with both eyes; a giant Panda eats around 28 pounds of bamboo a day;
Kangaroos can not walk backwards; and Hummingbirds' wings can beat up to 200 times a second.
Snakes do not eat any type of plant material, but small animals, including lizards,
frogs, other snakes, small mammals, birds,
eggs, fish, snails or
insects. Because snakes cannot bite or tear their food to pieces, they must swallow prey whole.
The blue whale, a marine mammal, is 98 feet (30
meters) in length and 190
tones or more in weight;
it is the largest existing animal and the heaviest that has ever existed. A new born blue whale measures 20-26 feet (6.0 - 7.9 meters) long and weighs up to 6,614 pounds (3003 kg).
As of 2024 and 2025, the estimated number of giant pandas living in the wild remains around 1,864, the same figure recorded in the 2014 census, reflecting a stable population thanks to years of conservation work including habitat
protection and breeding programs. Counting pandas in the wild is a massive undertaking, involving teams of researchers trekking through mountainous bamboo forests to find signs like dung and analyzing unique bite marks to identify
individual animals. Chinas expanded protected areas and the creation of the Giant Panda National Park have been pivotal, and although updated census figures are expected between 2025 and 2030, the current count stands as a testament
to ongoing conservation success.
The rarest animals in the world are listed below. Each of these species is rare for its own reasons, whether due to habitat loss, poaching, climate change, or simply being naturally scarce.
Over the past 250 years of taxonomic classification, scientists have formally identified over 1.2 million species across plants, animals, fungi, and microorganisms, yet this represents only a fraction of Earth's estimated 8.7 million
species, with more than 80% still undiscovered. On average, researchers discover 15,000 to 18,000 new species each year, often in remote ecosystems or hidden in existing museum collections, thanks in part to advances in DNA analysis and
improved exploration techniques that continue to reveal the planet's astonishing biodiversity.
Which came first, the chicken or the egg? The chicken - The scientists found that a protein found only
in a chicken's ovaries is necessary for the formation of the egg; the egg can therefore only exist if it has been created inside a chicken.
Globally, only 6.7% of the population holds a college degree, making it a relatively rare achievement worldwide. In the United States, about one-third of Americans have earned a college degree, though attainment varies significantly
by race and ethnicity: 49.8% of Asian Americans hold a degree, compared to 27.6% of Caucasian/White Americans, 17.3% of African Americans, 11.5% of Native Americans, and 11.4% of Hispanic Americans. These disparities reflect longstanding
differences in access to education, income levels, and systemic challenges that affect educational opportunities.
There are many interesting facts about Disney's Mickey Mouse. Some of these include Mickey Mouse made his debut on November 18, 1928 in Steamboat Willie at the Colony Theatre, New York City;
creating Mickey is not as simple, one cartoon could include 10,000 drawings; more than 100 Mickey cartoons were produced in the 1930s and were shown in theatres as films, newsreels and dramas and comedies; Walt Disney earned an honorary Academy award in 1932 for
creating Mickey Mouse; Mickey appeared in his first appearance in colour was in The Band Concert on February 23, 1935; in 1955, Mickey Mouse made his TV debut in The Mickey Mouse Club.
In the United States, individuals are taxed under a federal graduated income tax system with rates ranging from 10% to 37%, depending on income level and filing status, while corporations currently pay a flat federal tax rate of 21%,
replacing the previous graduated rates of 15% to 35%, which included a 34% rate for income between $335,000 and $15 million. Some corporations may also be subject to a 15% Corporate Alternative Minimum Tax if they earn over $1 billion
in adjusted financial statement income. Additionally, state income tax rates vary widely, from as low as 1% to as high as 16% when local taxes are included, with some stateslike Florida and Texasimposing no state income tax at all.
The Amish are a group of Christian people who choose to live very simple; they wear traditional, 18th century style clothes, and are known for reluctance to adopt many conveniences of modern technology, such as cars,
televisions, and computers. As of 2024, the Amish population in the United States reached approximately 400,910 and continued growing to around 404,575 by 2025, reflecting a rapid expansion of about 125% since 2000, far outpacing general U.S.
population growth. This trend is largely driven by the communitys high birth ratesfamilies typically have six to seven childrenand strong cultural retention. The majority of Amish still reside in Pennsylvania, Ohio, and Indiana, which
together account for over 60% of the total Amish population. Known for their Christian faith and rejection of many modern technologies, the Amish maintain a traditional lifestyle, including 18th-century-style clothing and limited use of cars,
televisions, and computers.
Christian is a person who adheres to Christianity, an Abrahamic, monotheisticreligion
based on the life and teachings of Jesus Christ. There were 2.2 billion Christians around the world in 2010, of which about 37% live in the Americas, 26% in
Europe, 24% in sub-Saharan Africa, 13% in Asia and the Pacific, and 1% live in the Middle East and
North Africa. By 2025, the global Christian population is estimated to reach around 2.71 billion, up from 2.63 billion in 2024, continuing to represent roughly one-third
of the worlds population. Sub-Saharan Africa now holds the largest share at about 28%, followed by the Americas with 24%, Europe with roughly 2022%, Asia and the Pacific with 16%, and the Middle East and North Africa with about 1%. This shift
illustrates the rapid growth of Christianity in the Global Southparticularly Africa and Asiawhile traditionally Christian regions such as Europe and North America experience slower growth or decline due to secularization and changing religious
dynamics.
Buddhism is a religion and dharma that encompasses a variety of traditions, beliefs and
spiritual practices largely based on teachings attributed to the Buddha. In 2010 there were about 495 million Buddhists, of which about 487 million lived in Asia, 3.9 million in North America, 1.3 million in Europe, and
1 million in the South America, Africa and the Middle East. By 2025, the global Buddhist population is estimated to reach around 508 million, up slightly from 506 million in 2024, with over 97% residing in Asiaparticularly in countries like China,
Thailand, Myanmar, Japan, and Vietnam. China alone is home to more than 254 million Buddhists. In North America, the number has grown to about 4.2 million, while Europe has reached around 2.5 million, reflecting gradual expansion beyond traditional
centers. South America, Africa, and the Middle East together account for fewer than 1 million Buddhists, though small increases have occurred, especially in urban areas. While Buddhism remains deeply rooted in Asia, its global footprint continues to
grow through cultural exchange, meditation practices, and broader philosophical appeal.
The first compound microscope was invented in the Netherlands around 1595 and is commonly attributed to Zacharias Janssen, who used a combination of convex lenses
to magnify small objects. In 1608, fellow Dutch spectacle maker Hans Lippershey invented the first telescope using a convex objective lens and a concave eyepiece, allowing distant objects to be seen more clearly. These groundbreaking
inventions laid the foundation for modern biology and astronomy by dramatically expanding humanitys ability to explore both the microscopic and cosmic worlds.
Lake Mead is the largest reservoir in the United States in maximum water capacity. It is 112 miles (180 km) long when the lake is full,
and 532 feet (162 m) at greatest depth, with a surface elevation of 1,221.4 feet (372.3 m) above sea level; it has 759 miles (1,221 km) of shoreline, 247 square miles (640) km of surface, and 28 million acre feet (35 km) of water when filled to capacity.
Honda built a walking humanoid robot in 1986. Honda began its humanoid robotics journey in 1986
with its first experimental bipedal robot, E0, which could walk in a straight line using a slow, static gait and had six degrees of freedom in its joints. This early prototype marked the launch of the E series, which over the following years
evolved into more advanced robots capable of dynamic walking and navigating stairs. By 1993, Honda had introduced the P series, culminating in the release of ASIMO in 2000an iconic, fully autonomous humanoid robot that showcased Hondas
decades-long innovation in robotics and remains one of the most recognizable robots ever built.
In 1999 Sony designed and sold a robotic dog (AIBO) with the ability to learn, entertain and
communicate with its owner. In 1999, Sony introduced AIBO, a revolutionary robotic dog designed to entertain, communicate, and learn from its owner, with its first modelthe ERS-110featuring 18 degrees of freedom for lifelike movement,
a 64-bit processor, and sensors that responded to touch, sound, and visuals. AIBO could develop a unique personality based on interactions, simulating emotions and behaviors that made it feel like a digital pet. Released as a limited edition
at $2,500, it sold out in just 20 minutes, quickly becoming a technological and cultural icon that earned awards and a spot in the Robot Hall of Fame.
As of 2025, video games are played across a wide range of platforms including game consoles, handheld systems, computers, and mobile phones, with the market now dominated by newer systems like the Nintendo Switch 2, PlayStation 5 Slim
and Pro, Xbox Series X and S, and the Steam Deck OLED. These consoles offer cutting-edge performance, portable gameplay, and access to massive libraries through services like Xbox Game Pass and Steam. While earlier consoles like the Nintendo Wii,
Xbox 360, and PlayStation 3 were iconic in their era, the industry has evolved dramatically, driven by technological innovation and players demand for immersive, cross-platform experiences.
Televisions first went on sale in the late 1920s;
color television sets were developed and become widespread in 1970s, and televisions with remote controls were in the market since early 1980.
Televisions first became available for sale in the late 1920s with early mechanical models, while color television gained widespread popularity in the 1970s due to technological advancements and more affordable sets. Remote controls
actually appeared in the 1950s with devices like Zeniths Lazy Bones, but it wasn't until the early 1980salongside the rise of cable TV and VCRsthat infrared remote controls became common household features, transforming how viewers
interacted with their TVs.

In the U.S., the president, who is elected by the entire country and serves a four-year term, is the head of the executive branch, which makes laws official. The president appoints or removes cabinet members and high level officials.
In the U.S., Senate there are 100 senators (two from each state) elected by their states and serve six-year terms. The U.S. vice president is considered the head of the Senate, but does not vote in the Senate unless there is a tie.
The Senate approves nominations made by the President to the Cabinet, the Supreme Court, federal courts and other important posts.
In the U.S., House of Representatives there are 435 representatives elected by their states and serve two-year terms. The Speaker of the House, elected by the representatives, is considered the head of the House.
If the U.S. president does not believe the bill is good for the country, he does not sign it; this is called a veto. However, with enough votes the legislative branch (U.S. Senate and U.S. House of Representatives) can override the President's veto, and the bill becomes a law.
Virginia is the birth state of the most presidents. Virginia holds the distinction of being the birthplace of more U.S. presidents than any other state,
with eight leaders originating there: George Washington, Thomas Jefferson, James Madison, James Monroe, William Henry Harrison, John Tyler, Zachary Taylor, and Woodrow Wilson. This early dominance in presidential lineage earned Virginia
the nickname "Mother of Presidents," reflecting its powerful influence as a founding colony and its prominent role in shaping America's early political leadership.
The Cathedral of St. John the Divine (in New York City), which was begun to build in 1892 and was completed in 2008, is the largest cathedral in the world: 601-ft wide at the nave and 320-ft wide at the transept.
