00:00Some men wear shoes with hidden heels to look taller.
00:04These shoes can grow up to 15 cm.
00:08They look like ordinary shoes, but they contain an additional sole inside.
00:13Sometimes this sole is fixed, sometimes it is removable, and you can choose the desired height.
00:20When the Titanic hit its iceberg and sank some time later,
00:24the Atlantic Ocean was about minus 2 degrees Celsius,
00:27which means that the water was below its freezing point.
00:30No wonder so many passengers did not survive.
00:34Some birds have a row of thorns protruding from the edges of their eyelids.
00:38These thorns are probably what could be called eyelashes.
00:42However, while human eyelashes are modified hairs intended to protect the eye,
00:47the eyelashes of birds are adapted feathers.
00:49Identical twins do not actually have the same fingerprints.
00:53So you can not impute your misdeeds to any devilish twin.
00:57Various factors during the development in the uterus, such as the position inside it,
01:02the length of the umbilical cord, and the rate of growth of the fingers influence the fingerprints.
01:10The speed of rotation of the Earth changes, it slows down right now.
01:14This means that on average, the duration of the day increases by 1.8 seconds every century.
01:20600 million years ago, a day only lasted 21 hours, which ...
01:26Most of the world's maps are incorrect.
01:28On most maps, we still use the Mercator projection,
01:32mentioned for the first time in 1169.
01:35But this very inaccurate method makes Alaska look as big as Brazil.
01:40While in reality, it is 5 times smaller than the latter.
01:44As for Greenland, it seems 14 times larger than it really is.
01:48For a map to be accurate, it should be on a real and round scale, rather than flat.
01:54Ants do not have lungs.
01:56They breathe through tiny orifices called spiracles.
02:00An ant can have 9 or 10 on each side of its body, depending on its species.
02:06The average color of the universe is poetically called cosmic light.
02:10In a study conducted in 2002, scientists discovered that the light from distant galaxies
02:15combined to create a beige color very close to white.
02:18Similar to the drink so much appreciated.
02:23There are negative decibels.
02:25The quietest place on Earth is the anechoic chamber of Microsoft in Redmond, in the United States.
02:31The sound level there reaches minus 20.6 decibels.
02:35These chambers are made of massive concrete and bricks,
02:38and rest on springs to prevent vibrations from penetrating the ground.
02:44Bananas are radioactive.
02:46Wait, where are you going?
02:48It's not that bad.
02:50Bananas are rich in potassium,
02:52and each banana is slightly radioactive due to the natural isotope potassium-40.
02:57In addition, your body contains about 16 mg of potassium-40,
03:03which makes you about 280 times more radioactive than a banana.
03:08In addition, it eliminates the excess of potassium-40 from a banana in just a few hours.
03:16There is simply no perfectly straight line.
03:19By zooming in enough, you will inevitably discover irregularities.
03:23Even the beam of a laser has a slight curvature.
03:27In case of emergency, fish form ordered lines.
03:31When they have to evacuate through narrow passages to escape danger, for example,
03:35the tetraneon bands line up to avoid bumping or blocking the way.
03:40Researchers think that this behavior indicates
03:45that fish are able to respect social rules even in crisis situations,
03:51unlike us humans.
03:56Hippos are unable to swim.
03:58Their bones are so large and dense that they barely allow them to float.
04:04Thus, these animals do not swim,
04:06but perform a kind of slow gallop against the bottom of the river.
04:09Hippos can also sleep underwater
04:11thanks to a reflex that allows them to go back to the surface,
04:14to take a deep breath,
04:16and then go back to the bottom without waking up.
04:21Lego blocks resist compression better than concrete.
04:25An ordinary plastic brick
04:27can withstand the weight of 375,000 other bricks before breaking.
04:32Theoretically, this would allow to build a tower of more than 3,200 meters high.
04:37But if we had to make bricks the size of a house,
04:40the cost would be prohibitive.
04:43If you ever go into space,
04:45you can take your yo-yo with you.
04:48In 2012, NASA astronaut Don Petit
04:51took his yo-yo aboard the International Space Station
04:55and used it to show a few tours.
04:58You see, a yo-yo rests mainly on the laws of angular conservation
05:02to make turns.
05:04And if you keep the string taut,
05:06these laws also apply in microgravity.
05:08There is a theory according to which
05:10we sweat when we are anxious
05:12to alert the brain of other people
05:14that they must prepare to face the danger
05:16that causes this anxiety.
05:18Brain imaging studies have shown
05:20that when you sniff the sweat produced by a person in panic,
05:23the regions of the brain responsible for emotional and social signals
05:26are activated.
05:28And when you are anxious,
05:30your sympathetic nervous system produces hormones,
05:32including adrenaline,
05:34which activates your glands.
05:36There are sky arches on Venus
05:38and they are called gloirs.
05:40A gloir looks like a series of colored concentric rings
05:42and is caused by the interference of light waves
05:44inside the droplets
05:46rather than by the process of reflection,
05:48refraction and dispersion
05:50of the light that produces the sky arches.
05:53Protons can take the form of donuts,
05:55spheres, peanuts
05:57or rugby balls.
05:59In other words,
06:01they decline under different shapes and sizes.
06:03Their appearance changes depending on the speed of the quarks,
06:05the smaller particles that make them up.
06:07If you look at the Moon
06:09from the southern hemisphere,
06:11it will seem to be upside down
06:13and the famous man in the Moon
06:15will look more like a rabbit.
06:17You will remember more of your dreams
06:19if you sleep badly
06:22You will remember more of your dreams
06:24if someone or something wakes you up
06:26in the middle of the night.
06:28Dogs tilt their heads
06:30when they listen to people
06:32to better spot familiar words
06:34like promenade.
06:36This also helps them to better understand
06:38the tone of your voice.
06:40It is also said that if a dog does not often tilt its head,
06:42it is because it depends more on its sight
06:44than its yes.
06:46When two mirrors face each other,
06:48they do not produce infinite reflections.
06:51Each successive reflection
06:53becomes darker than the previous one
06:55and ends up disappearing.
06:57Mirrors absorb a tiny fraction
06:59of the luminous energy that strikes them.
07:01As a result,
07:03the total number of reflections
07:05that a pair of mirrors can produce
07:07is limited to a few hundred.
07:09You can smell ants
07:11because many species
07:13produce strong-smelling chemical substances
07:15when they feel threatened,
07:17angry or crushed.
07:20Odontomachus ants
07:22release a chocolate smell
07:24when they are crushed
07:26while Lasius ants
07:28emit a citronelle smell
07:30when they are in danger.
07:32Giraffes emit a murmur
07:34to communicate with each other.
07:36Researchers think that this low-frequency murmur
07:38could be a form of contact scream
07:40between individuals
07:42separated from their herd.
07:44It can also help them to find themselves
07:46in the darkness.
07:48Despite these majestic creatures,
07:50some scientists think
07:52they also speak in their sleep.
07:56And here is an interesting anecdote
07:58just for you
08:00about a marathon runner
08:02who took more than 50 years
08:04to finish his race.
08:06The Japanese marathon runner
08:08Shizo Kanakuri
08:10was selected as one of the two athletes
08:12that Japan could send
08:14to the 1912 Stockholm Olympics.
08:16It turned out that
08:18after an exhausting 18-day trip
08:20to Stockholm,
08:22first by boat then by train,
08:24Kanakuri was exhausted.
08:26During the race, he stopped
08:28because his condition
08:30did not allow him to continue.
08:32He found himself in a garden party
08:34where he drank orange juice
08:36and rested.
08:38Ashamed of his failure,
08:40Kanakuri returned later to Japan
08:42without informing anyone,
08:44the Swedish authorities considered him
08:46as missing for 50 years
08:48before discovering that he lived
08:50peacefully in his native country.
08:52In 1967, he was given the opportunity
08:54to finish his race,
08:56which he accepted.
08:5854 years, 8 months, 6 days,
09:005 hours, 32 minutes
09:02and 20 seconds
09:04after starting his marathon,
09:06he finally finished it.
09:08It was a long journey
09:10because in the meantime,
09:12Kanakuri had 6 children
09:14followed by 10 grandchildren.
