G'day I'm Jesse Crowe, The Travelling Scientist, here in Czech Republic and today,
we're gonna be looking at some Czechian science.
So I'm not going to lie, today's video was supposed to be about the science of beer and
beer brewing but unfortunately it's not peak season in Czech Republic,
so every time I went to a beer brewery it went a little something like this...
uh, brewery tour?
Hmm? NO!
So beer science is going to have to wait for another day.
Instead, I'm going to teach you some awesome facts about this country, Czech Republic.
Fact number one, Czech Republic is trying to change it's name to Czechia.
It sounds a little bit nicer, Czechia, versus Czech Republic!
If you look it up on google maps, you'll see that where Czech Republic should be,
it actually says Czechia.
So if you see the name Czechia anywhere, now you know what it means.
I realise thats not a very sciency fact but...it's interesting right?
Fact number two, Czech people are the most passionate beer drinkers in the world!
They love their beer, they drink 142 litres per person, per year.
That is a medium sized wheelie bin full of beer, can you imagine that!?
Wait...don't, don't imagine that.
Germans drink just over 100 litres a year, and Australians,
we only drink 72 litres a year, come on guys, shape up!
Fact number three, something very useful was invented in Czechia.
I'll give you a hint, it's very small, it's made out of a polymer, it stretches,
you use it on a sensitive part of your body, and when you're done with it, you chuck it away.
That's right, it's contact lenses!
They were invented by a Czech chemist named Otto.
He created a cross linking polymer called poly-hydroxyl-ethyl-methacrylate, or pHEMA.
This material acts as a sort of gel that can absorb water and sit comfortably on the eye
and it refracts and focuses light to make objects seem clearer to the person who is wearing it.
Thanks Czechia!
Fact number four, Johannes Kepler was a famous astronomer and mathematician.
He was German but he created the three laws of planetary motion
while living in Prague in the year 1600.
Those laws are that 1: All planets revolve around the sun in an elliptical motion.
2:Planets revolve faster when they are approaching the sun and slower when they are moving away from the sun,
and 3: The amount of time it takes for a planet to revolve around the sun
is dependent on its distance from the sun, so planets that are further out take longer
because there is a weaker pull from gravity.
And these laws helped Isaac Newton define gravity less that 100 years later, and where would we be without gravity?
Fact number five, Czechia is beautiful...
So that's just a few of the scientific facts that I've picked up while living here in Czechia.
Sorry I didn't tell you more about beer, but I promise I'll do a beer science video in the near future.
Alright, I'm off to Austria next so keep an eye out for that video.

He created a cross linking polymer called poly-melthyl...helthyl...*jibberish*
Called poly....
Sorry I didn't talk more about beer, but I promise I'll do a beer about the...promise
I'll do a beer?
