let's watch some tick tocks so make sure you subscribe you've got to click again
for the bell notification otherwise i'm like dark matter and you won't be able to see me
anywhere thanks to squarespace for sponsoring this video talk more about squarespace later
that's like a cold atom top trap role of the story you could learn to ride
a horse as long as it spins around like a tornado
what is this why does she have physics and so i believe in the conservation of energy so i know
that if i let it go it's gonna go away and not come back and hit me right so now i want you to
show me if you believe he's just waiting for the dates when he does this wrong but accidentally
pushes it so now let's bring this back let's back up a little bit ready no right wait so now let
don't hold your hands up i let go let go i'll hold it do you believe in the conservation of energy
yes don't don't take your hat don't move your head at all okay ready don't think do you believe
not bad
right
when you've studied physics for years like me you can actually do things like this
patience my young padawan to become jedi master physics you must to master physics you must become
thus nerd equals jedi ruler on the table you drop something on it it's gonna fall okay but if you
put an ordinary piece of paper on the ruler over here just put it like that and you drop something
the reason why when she puts a paper on there it doesn't do it is because of air pressure
so you've got all of that air above the piece of paper on it top of it that's why
this works so it's just air pressure um and you can do the same experiment and break like a wooden
ruler this way if you hit it hard enough it will actually break the wooden ruler so you might think
because it's out of frame she might have like put something on the side but let's go another version
just so you guys can believe this
did you know the solar system is shaped like a croissant is it really the sun creates this
protective bubble around the planets in our solar system called the heliosphere
except it's not a sphere it used to be believed to be shaped like a comet's tail
but now it's more like a croissant and the model that produced this result is based off
observations and theoretical astrophysics so yeah this video is making me hungry kirsten
before we get onto the next tick tock excuse me whilst i go find a result
okay no croissant but i have something even better i found a cookie
so i'm going to eat the scooby and we're going to watch some more tick tocks
all right this one looks fun one weird trick if you're ever feeling sad or depressed about
the state of the world here's one weird trick that always works for me get in
underground
this guy's awesome and remind yourself that humanity is still capable of incredible things
it's all fun and games until the entire mcu comes through why does our universe exist i can't help
you with that one mystery okay what's with this mystery hot on the moon business china's u22 rover
has spotted this on apparently cubes shaped hot while roving on the far side of the moon and china
has informally named it shen means yahweh meaning mystery hut definitely actually a hut probably not
most likely it's a vulgar rock just like when this face on mars turned out to be just a flat
hill but u22 is slowly making its way towards this mystery hunt over the next few lunar days
where a lunar day is equivalent to 29 days 12 hours and 44 minutes on earth so we can expect
to get more information about this mystery hut early in the new year and it was a wrong
good call astro kirsten okay someone sent me this video and told me this physics in it
i was the island boys high school teacher very nice young man this is alex aka fly soldier
and before he wanted to be a rap star alex actually brought in a uh little nasa
astronaut shuttle to career day and he said he wanted to live on a star
it was at that point that his brother uh started to yell at him explaining that stars were made of
gas and that he would burn up that really upset alex so they got into a physical altercation
i had these two kids rolling around the floor punching one another arguing about the physics
of a star and whether or not you could actually inhabit it well there you go one of the island
boys was an aspiring physicist hey everybody james here at cern come here you gotta see this
so you know how i'm always talking about these gigantic magnets that we have here at cern you
know the 1200 dipole magnets that we put 100 meters underground into the 27 kilometer circular
tunnel of the large hadron collider each of which has a magnetic field that's a hundred
thousand times greater than the earth's magnetic field and these are the only things that allow us
to accelerate protons to the highest energy that humans have ever used in a collider experiment
to explore the mysteries of the universe this this is where the magnets are born
when the magnets are nearly ready they look something like this
and then they undergo a whole series of tests and trainings before eventually they end up in those
blue tubes that are lowered 100 meters underground to the large hadron collider tunnel you should
make an explainer yeah you're probably right those dipole magnets are like one of the most complex
parts of the lhc they basically bend and align the trajectories of the particles and keep it stable
believe it or not these aren't even the strongest magnets in the world and i think the largest one
in the world currently is powerful enough to pick up an aircraft carrier it is for the heart of the
largest fusion reactor in the world item which means the way in latin so for the other physicists
and mandalorians out there this is the way this is why high-powered can magnets be dangerous i had a
stroke this reading but yeah magnets are dangerous guys be careful we can create art objects by using
potato physics everyone knows that plastic straws are not sturdy enough to pierce erotic but
now i will use physics i will cover the top of the straw with my finger
in this straw it will create pressure destroy stop the tatiana again more
yes
mvp of the planet
you just realize the speed of light i can't even hit a ping-pong ball that fast wait what
i could probably outrun that i thought light was filming is that most light as fast
everyone seems so confused but if you grab the egg and you throw it okay it's bouncy
all right it's bouncy but then if you take the egg and you smash it
not that hard it's just physics you should definitely try this experiment yourself
what i'm about to show you is a picture from one of my first year physics lectures
where my lecturer asked me to come to the front of the classroom and do this sandwich in between two
beds of nails and then stand on top of him i can guarantee that his trust was not with me that day
it was instead with physics this lesson was in the distribution of forces if i were to
apply my weight force on one single nail on my lecturer it will almost certainly pierce the skin
and do some good damage but when you apply that same force over multiple nails the force on each
individual nail decreases significantly meaning that you barely make an indent in the skin is fine
and if this wasn't terrifying enough to do he then asked me to put a block of concrete on it and then
break it with a hammer that was in front of 500 physics and engineering students
lucky you didn't get me to come stand on that
board because i eat way too many of these things i'm gonna break physics
it's not exactly bright so how about you guys leave the correct answer in the comment section
and i'll like the correct answer so you guys can check what the answer is and we'll let it go now
you know that it's turning around in circles in fact if you look at it from above you can see
that it's turning around in a circle but now your brain is doing something strange it's telling you
that it's not going around in a circle but it's oscillating in other words it's turning part
way stopping and then going back the other way but if you think that's strange wait till i add
something through the middle what am i going to add well i'm going to add a ballpoint pen
but what's your brain going to tell you about the window will your brain allow you to see the
window going around in a circle will with the pen or are you going to see something really strange
look at that it feels unbelievable isn't it you can see the pin going in the matrix everyone but
your brain is telling you you're just trying to figure out how the thing is going the other way
and yet in order to do that the two things have to pass through one another you know
it's not possible you know it can't happen you want to see a neat physical demonstration this
plate on the left is currently loaded with positive charge and the plate on the right
has negative charge look what happens when i put this neutral ping pong ball in the middle really
so someone asked why is this not a perpetual motion machine well every time the ball touches
the plates it takes a little bit of charge eventually the plates lose all their charge and
the ball stops the reason why it doesn't look like that here is these plates probably continuously
receiving charge so you're not getting energy just from nothing if you haven't already why not start
