Here are 50 amazing Physics Facts! Space has a
smell.
It's been described as a mix between
barbecued meat, hot metal and fuel. The
super soaker was invented by a NASA
scientist. The Eiffel Tower is 15
centimeters taller in summer than winter.
This is because of thermal expansion,
where the extra heat causes the metal to
expand. If the red supergiant Betelgeuse
exploded into supernovas it would light up our
skies for two months straight.
This could happen anytime, within a
thousand years, tomorrow, or even now...
Scientists from Mexico have successfully
made diamonds from tequila. If you
removed all of the empty space from the
atoms that make up all of the humans on
Earth, the remaining mass could fit
inside a sugar cube. Looking at stars is
basically looking into the past because
of how long it takes the light from them
to reach us. Tesla was obsessed with
creating a death ray, which he claimed
to have created before he died. He also
hated shaking hands with people, had OCD
and fell in love with a pigeon. Splenda
was discovered whena scientist mishead
his coworker saying "test this chemical". He
thought he said "taste this chemical".
Humans can only physically see two
dimensions, left and right and up and
down. The third dimension, depth or
forward and backward, is a perception
your brain creates from 2 2d images. You
can't burp in space because there's
no gravity to separate liquid from gas
in your stomach. When NASA landed on mars
three men from Yemen sued them for
trespassing, claiming that they had
inherited the planet from their
ancestors. The world's roundest object is
a silicon sphere crafted in Australia,
and may become the new definition of the
kilogram. Sound waves at ultrasonic
frequencies can levitate objects in
what's known as acoustic levitation.
Isaac Newton once shoved a needle into
his eye to see if it would affect his
vision. If you put Saturn in water, it
would float. If you shuffle a pack of
cards properly, chances are that exact
order has never been seen before in the
entire history of the universe. Because
the dangerous nature of their jobs, the
Apollo astronauts couldn't apply for life
insurance.
Instead they signed a pile of
autographs hoping that they became
valuable if they died.
The sky is blue because molecules in the
air scatter blue light more than the other
colors of light. The blue light bounces
off those molecules and hits your eyes,
making you see blue. A physicist named
Jack Hetherington make his cat the
co-author of a paper because he'd
accidentally written "we" instead of "I"
throughout the paper and couldn't be
bothered changing it. When helium is cooled
to almost absolute zero it becomes
what's known as a superfluid. It flows
against gravity creeping up and over the
side of containers. All black holes have
a point of no return called the Event
Horizon. Anything that passes beyond this
point gets sucked in and is lost
forever, even light. If you want to get
sucked into a black hole your body would
be stretched out in a process scientifically
called Spaghettification.
Richard Feynmann used to go to strip
clubs to do work on quantum mechanics.
Lightning can reach temperatures five
times that of the surface of the sun.
Homing pigeons can't navigate on mercury
because of the lack of magnetic field
and atmosphere. Sunlight reflects off
water at the same angle it shines onto
it.
Mars' two moons are named Phobos and
Deimos, literally translating to Fear and
Panic. The highest temperature ever
reached on earth was four trillion
degrees Celsius. This was at the Quark
gluon plasma this was a this was at the
Quark gluon plasma at Brookhaven. If you
cry in space, the tears just stick your
face.
Quantum computers use the spin of an
electron to store information called
quantum bits. This allows them to perform
complex calculations way faster than
classical computers. William Herschel, the
astronomer who discovered Uranus,
actually named it George after King George
the third. It was later renamed after the
Greek god of the sky,
Uranis. The amount of heat in the Earth's
atmosphere is equal to the amount of
heat in the first 10 feet of the ocean.
Werner Heisenberg, who is famous for his
uncertainty equations in quantum physics,
nearly failed his doctoral exams because
he knew nothing about experimental
techniques. When he was asked how a
battery worked, he had no idea.
There's a giant gas cloud in the
constellation of Aquila that contains
enough alcohol to make four hundred
trillion trillion pints of beer. Tesla is
on the front of the Serbian 100 dina bank
note. The big bang theory was invented by
a Catholic priest. The first man on the
Moon, Neil Armstrong, actually got the
famous moon landing line wrong. He said
"one step for man, one giant leap for
mankind".
It should have been "one step for a man,
one giant leap for mankind'. A bolt of
lightning has enough energy to toast
100,000 slices of bread. The electrical
force is about a billion billion billion
billion times stronger than gravity.
If you were standing at arm's length
from someone and each of you had one
percent more electrons than protons,
the repelling force created would be
enough to lift a weight equal to the
entire Earth. The physicist Thomas Young
did an experiment which proved that
light was a wave. About a hundred years
later Einstein did an experiment that
proved that light was a particle. Light
is actually both a particle and a wave
depending on how you're looking at it.
This is called wave-particle duality.
There's a planet where it rains glass
sideways.
According to the Heisenberg uncertainty
principle, we can't know the exact
position and momentum of a particle at
the same time. Your head is older than
your feet. According to Einstein's theory
of relativity, time moves faster the
further away you are from Earth,
meaning that unless you spend a lot of
time upside down your head ages slightly
faster than your feet.
It takes a photon about 170,000 years to
travel from the core of the Sun to the
surface of the sun, and then just another
eight minutes to travel from the surface
of the sun to your eyes. Hardness is
different to toughness. Hardness is a
material's ability to resist being
deformed, while toughness relates to how
much energy a material can absorb
before breaking. The Sun makes up more
than ninety-nine percent of the entire
mass of the solar system. There's a particle
with the exact same mass and charge as
an electron, except that it's positive.
Its suitably called a positron. The
coolest star temperature-wise ever
discovered was made entirely out of
diamonds and contains 10 billion
trillion a trillion carrats. If you hold
up a grain of sand, the patch of sky it
covers contains 10,000 galaxies. Light
doesn't need a medium to travel in, but
sound does. This means that there would be
no sound in space as space is just one
giant vacuum. And that was 50 physics facts!
