What's the deal with wind? And why does it have to be so...windy?
How did people move stuff around before the wheel was invented? More importantly, why didn't they take a break for a few minutes from moving stuff...

We hear nuclear power is explosively popular. Eh? Eh? ...Don't tell us to keep our day jobs. This is our day job.

No you're not here shmoop er's we know the questions

that have been keeping you up at night and we're

here to answer him I'll soon you'll never have to

wonder about why electrons generate power when they moved from

first place not questions that will keep you up at
- 00:20
night There everybody's a critic Well they were keeping someone
- 00:24
up at night A certain albert einstein And lucky for
- 00:27
us you figured it out The answer surprisingly simple e
- 00:32
equals m c squared In other words energy and matter
- 00:35
are the same thing And good thing we figure that
- 00:38
out because in the last two centuries human technology and
- 00:41
human knowledge of energy have taken huge leaps forward harnessing
- 00:44
wind and water allowed cities to grow and you know
- 00:47
have huge populations who need to be bed that steam
- 00:51
and coal started the industrial revolution and oil and electricity
- 00:55
spread mechanical advances to most of humanity during the twentieth
- 00:59
century At that point we pretty much thought that all
- 01:01
possible energy sources had been found harnessed and put to
- 01:05
work We're like work here's done fellas All innovation is
- 01:10
over Nothing else to do but sit back Chow on
- 01:13
tacos and watch tv Boy where we run in the
- 01:17
mid twentieth century we discovered an energy source with the
- 01:20
power to annihilate entire cities or provide electricity for millions
- 01:24
of home The first time in human history our energy
- 01:26
no longer came solely from the sun It's a matter
- 01:29
of fact we discovered what powers the sun in the
- 01:32
first place Yep We discovered nuclear power which turns matter
- 01:36
into pure energy And yeah we freaked out a little
- 01:39
bit We're still freaking out It's Intense stuff Some people
- 01:43
thought it was the end of the world Others thought
- 01:45
it was the miracle cure for all of our energy
- 01:48
problems Either way it was new It was unheard of
- 01:51
And it was kind of scary Like the first time
- 01:53
you had a crush on someone except not like that
- 01:56
at all months Nuclear power talk about anyway around nineteen
- 02:00
hundred people believe that adam's were totally solid like unimaginably
- 02:05
tiny pool balls Remember all that stuff about electricity and
- 02:08
moving electrons Yeah they had no idea what they were
- 02:10
doing but hey they couldn't even see adam's until the
- 02:13
invention of the electron microscope in nineteen thirty one so
- 02:18
give him a break Atoms are not solid They look
- 02:21
more like a mini solar system with a nucleus instead
- 02:24
of a son and electrons instead of planets Even more
- 02:27
alarmingly adams don't always stick together Sometimes atoms decay and
- 02:32
lose particles well This decay creates radiation a waves of
- 02:36
nasty energy and particles Radioactive decay happens in small amounts
- 02:41
all the time but hey depress everyone nobody freak out
- 02:45
Every piece of matter around us is not out to
- 02:48
kill us with radiation brings out that when adam's fall
- 02:52
apart they released energy And if we smash them on
- 02:56
purpose we can really make a lot of this stuff
- 02:59
the first time that human beings intentionally split and adam
- 03:01
was in nineteen thirty eight when two german scientist named
- 03:05
hahn and strassman blasted uranium atoms with other particles while
- 03:10
less scientific minds were blasting cans for fun Hahn and
- 03:14
strassman had noticed that a surge of energy happened when
- 03:17
uranium atoms or smacked around only they could make it
- 03:21
happen over and over and over again In a chain
- 03:23
reaction they could have produced unimaginable amounts of energy and
- 03:28
after the first nuclear reaction was created people naturally wondered
- 03:32
if nuclear power could be used as a weapon Because
- 03:35
it was the nineteen forties the entire world was at
- 03:38
war again and nuclear power would have been a pretty
- 03:41
sweet trump card Well as oppenheimer the head scientist of
- 03:44
america's nuclear bomb program said after successfully setting off the
- 03:49
first avon i am become death the destroyer of worlds
- 03:54
melodramatic but was not exaggerating Once again humanity had taken
- 03:59
a potentially beneficial new discovery Hand made it lethal Insert
- 04:03
a complete lack of surprise here This is why we 00:04:06.405 --> [endTime] can't have nice things
