No surprise here, this is used as a defense tactic to ward off predators who may attack them.
It takes approximately 50 milliseconds for visual information to process in your brain, by the time you actually see something, it already happened.
Depending on the breed, snails can have 2,000-14,000 teeth! Most snails are herbivores, their teeth are used for scraping or tearing their food.
Because their bodies do not contain bones, an octopus can squeeze through anything so long as their beak can fit.
Our brain ignoring our own nose is a part of binocular vision, and peripheral vision may also play a role in why our brain is able to ignore the sight of your nose all day.
Saturn is predominantly comprised of hydrogen and helium gas, giving it an overall density lower than that of liquid water. However, since the planet is not a uniform, rigid object, we can’t be sure that it would float without further experimentation. That’s an experiment that would take an awfully big laboratory!
The average lightning strike contains about 1 billion joules of energy. To power an average 800 watt toaster, it would take around 48,000 joules of energy to power the toaster for one minute in order to toast the bread. So, 1 billion joules of energy in a lightning strike equals around 20,000 pieces of toast.
The Kármán line, which is commonly represented as the boundary between Earth's atmosphere and outer space, is at an altitude roughly 62 miles above sea level. This means if you could drive straight up going 60mph you would arrive in outer space in just over an hour's time.
We know, what?!?!
Check out our math... (average 5,900 steps/day) x (365 days/year) x (78.9 years/life) x (I mile/2112 steps) x (1 Earth/24,901 miles) = 3.2 Earths/life
If you assume a grain of sand has an average size and you calculate how many grains are in a teaspoon and then multiply by all the beaches and deserts in the world, the Earth has roughly (and we're speaking very roughly here) 7.5 x 1018 grains of sand, or seven quintillion, five hundred quadrillion grains. If we have a Hubble telescope and a calculator, we can count distant galaxies, faint stars, red dwarfs, everything ever recorded in the sky. The population of stars jumps enormously, to 70 thousand million, million, million stars in the observable universe (a 2003 estimate), so that we've got multiple stars for every grain of sand.
Sound is the energy things produce when they vibrate. Just like the movement you're creating and the corresponding sound you hear, slower waves produce lower sounds, while faster waves produce higher sounds.
Female mosquitoes use the blood from humans and animals as a protein source for their eggs. Additionally, male mosquitoes do not have the same mouth part female mosquitos do that are needed for sucking blood.
Had to think about that one, didn't you?
An astronaut's burps are different than those experienced on Earth. If an astronaut does burp in space, it comes out as a wet burp! Gross!
Wright Brothers' first flight was December 17, 1903 and Apollo 11 was July 16-24, 1969, so roughly 65.5 years between the two events. The Wright Brothers flew the Wright Flyer at Kitty Hawk and flew a distance of 120ft and lasting only 12 seconds. The flight for the crew of Apollo 11 lasted for 8 days, 3 hours, 18 minutes, 35 seconds.
Male seahorses have a pouch on the ventral, or front-facing, side of its tail. When mating, the female seahorse deposits up to 1,500 eggs in the male seahorse’s pouch. For the next 9-45 days, the male carries the eggs until they baby seahorses emerge.
Add up the speed of the rotating earth, the earth revolving around the sun, the sun moving in the milky way, and the milky way moving through the universe and you get one fast speeding ticket.
Bees add an anti-microbial protein to honey that prevents bacteria from growing, which is why it doesn't spoil.
The first lighter was invented in 1823 by German chemist Johann Wolfgang Döbereiner. His device was often referred to as “Döbereiner's lamp.” While various forms of matches have been around since ancient times, the first successful friction match (like the ones we use today) was not invented until 1826 by English chemist John Walker.
It can actually flow even faster than a sprinting greyhound! Pyroclastic lava flows, similar to the Mount St. Helens eruption in 1980, can travel several hundred km/hour.
The atmosphere on the Moon is very different from what we experience on Earth. The air there is literally and figuratively worlds apart. There is no wind, water, or other forms of weather to erode the footprints left behind by astronauts.
On Venus, one rotation on its axis takes the equivalent of 243 Earth days and the planet's orbit around the Sun takes the equivalent of 225 Earth days.
There are 500,000 sweat glands in your feet that are capable of producing a pint of sweat throughout the day.
The sun rises at the North Pole on the Spring Equinox around March 21st. For the next six months, the sun is always visible in the sky. Its maximum height, similar to our “noon,” occurs at the Summer Solstice around June 21st. The sun sets at the North Pole on the Fall Equinox around September 21st. Although the sun is below the horizon for the next six months, the area is not in total darkness. The pole experiences periods of twilight before and after the lights go out. The South Pole follows a similar pattern, but in reverse! When the sun rises at the North Pole, it sets at the South Pole.
Cumulus clouds are the fluffy white clouds that fill the sky on a clear, typically sunny, day. The weight of these clouds is determined by their water density, which equates to about 1/2 gram per cubic meter!
Caffeine withdrawal is a real condition with neurochemical causes. Common symptoms include headache, fatigue, difficulty concentrating, and dysphoric mood.
The design of a hummingbird's wings differs from most other types of birds. Hummingbirds have a unique ball and socket joint at the shoulder that allows the bird to rotate its wings 180 degrees in all directions. The shape of their wings are long, narrow and tapered, which allows them to move more quickly and easily through the air. Additionally, the shoulder and elbow joints of the wing are very close to their tiny bodies, allowing the wings to tilt and pivot. These characteristics allow hummingbirds to change flight directions in a way other birds cannot.
Some scientists state that consciousness, the ability to be aware of yourself and your surroundings, is caused by physical properties. They use mathematics to graph an experience and map this experience to the brain.
Start by shaping an extremely clear piece of ice into a disc that is thick in the middle and narrow at the edges. Now, smooth away any rough edges with the warmth of your hands. Angle your ice lens towards the sun, focusing the light on a pile of tinder. The ice acts as a convex lens, directing photons to a localized point. The resulting concentration of heat energy can reach extremely high temperatures, allowing the tinder to catch on fire. This is sometimes easier said than done — the purity of the ice, thickness of the lens, and quality of tinder can all affect the process.
The sun is large enough that approximately 1.3 million Earths could fit inside. Want to check our math? The volume of the sun is 1.41 x 1018 km3, while the volume of Earth is 1.08 x 1012 km3. If you divide the volume of the sun by the volume of the Earth, you get that roughly 1.3 million Earths can fit inside the sun. However, this assumes that the Earths are squished together without leaving any empty space. Scientists estimate that if the Earths retained their spherical shape, only about 960,000 would fit because of wasted space in between the spheres.
2+2 is always 4 no matter what symbols you use to communicate it.
Even though dinosaurs like T. rex and Alamosaurus have faded into extinction, birds have adapted to survive. There are many astonishing links between prehistoric dinosaurs and modern-day birds.
On average, the International Space Station travels at a speed of 17,500 mph at an altitude of 248 miles above Earth. The ISS orbits Earth 16 times a day, so astronauts living and working there experience a sunrise and sunset every 90 minutes.
Peregrine falcons can top speeds of 240mph while cheetahs can only reach speeds of 75mph.
Over the course of one year, this will amount to 16 million storms across the Earth!
Why are you seeing a new color when the wheel spins? The colors are spinning at such a rate that your brain is unable to process them as the individual colors that are on the wheel. Instead, your brain takes a shortcut and creates the secondary colors.
Scientists estimate that each human cell would contain about six feet of DNA if stretched end to end. Multiply that length by the trillions of cells in our bodies and you get a lot of trips to the Moon!
The pigments in their skin (one which has been named hipposudoric acid) help absorb harmful UV rays. This secretion has anti-bacterial components as well. Hippos still need to stay well hydrated, which is why you probably find them in water or covered in mud!
Plants too! If you added it all up, 50% of all animals and plants on Earth can be found in the rainforests.
Water covers nearly 70 percent of of the globe. The majority is undrinkable, ocean-based water. 2.5 percent is fresh and of that 2.5 percent, just 1 percent is accessible - the remainder is trapped in snowfields and glaciers.
On Saturn and Jupiter, atmospheric pressure is so high it is possible amorphous carbon could be converted to diamonds.
Peanut butter can be converted into diamonds by subjecting it to extremely high temperature and pressure. Be warned- the quality of diamond produced by the peanut butter won't be something to write home about. The resulting diamonds are typically very small and tend to be muddy in color.
Scientists compare DNA sequences in many ways. We can look at single differences, for example one person might have the sequence GATCCTAG and another GGTCCTAG. We also look at the number of times these regions repeat, for example one person might have the sequence GGTCCTAG and another have that same sequence repeated 3 times. Our methods are continually being updated, but we always find that human DNA is overwhelmingly more similar than it is different.
While mammals have seven neck vertebrae, sloths have eight or nine. The reasons for the extra vertebrae are not clear, but might contribute to their ability to turn their necks farther than other mammals.
That's all of the facts for now, but we have plenty more to discover! Check out our cooler than cool exhibit halls to amaze your brain even more!
