well hello children and welcome to the
history of the entire world class today
we are traveling back in time to meet a
famous mathematician named sir isaac
newton so the first thing we do is we
hike up our pants a little bit just like
this and we wiggle our toes a little bit
just like this and then we are uh dance
right back through time right back to
the ripe old year of 1665.
you see one day mr sir isaac newton is
sitting under this her tree which
happens to be an apple tree and he was a
writing in his diary when all of a
sudden
uh when all of a sudden
oh no kids you see what's supposed to
happen right now was an apple supposed
to fall from this tree
onto that man's head
and it's very funny you see but
something else happens to something very
historical
i know
i've seen this while traveling through
history from time to time we must be
stuck in a thought bubble
a brain fart
if you will you see a brain fart
is when you get stuck in an idea and you
can't solve or figure something out and
all of time freezes until you figure out
the right answer so we need to help out
this guy right here right excuse me
sir mr sir isaac newton sir
yes who's there i missed her or uh his
turn i'm a big fan of your work yes well
i have this mathematical problem that i
just can't figure out and i'm having a
bit of a brain fart
i knew i smelled a brain fart
well maybe we can help you out oh that
would be amazing because i just feel
stuck today so here's the problem i have
these ten apples up there in the
branches see and i'm trying to imagine
how many would be there if there were
four or less for you see my wife needs
four apples for making her classic four
apple pie well that sounds like a real
problem now let's work through this so
let's count these apples first
one
two
three
four
five
six seven eight
nine ten yeah ten there's ten very good
now you
want to imagine what it would be like to
have four less apples you're saying the
equation is actually ten minus four yes
oh but that's not really that much help
i'm still exactly where i started oh
we'll never figure this out and i'll
never be a great mathematician
sheets
this guy has gone bananas
now we have to count bananas too
oh
hold on right there mr sir isaac newton
i have an idea what if we count out four
apples that are right near each other
one two three
four four yeah there's four and we cover
those up with our hand so it's like they
went away
okay
now what well now we just count the rest
of the apples that aren't covered up to
see how much would be left
one
two three four five six yeah there's six
six apples remain so ten minus four
equals six you better write that one
down
i will well let's stand back now kids
and see if we fixed history
so there's sir isaac newton writing in
his diary and all of a sudden
ouch
an apple falls on his head and in that
moment
eureka
sir
newton realized that all things were
pulled down from the air towards the
center of the earth and he called this
theory gravity which is pretty awesome
since that's what keeps our bodies here
on the ground because without it
we'd all be floating around
like we're in space
yeah space
i remember space
very
relaxing
gravity huh
well
see you guys next time
bye
hey
