hey esauce Michael here do you have a
best friend who is there for you 247
365 sorry that's not really good enough
if your friend truly had your back they
would be there for you
24.6 7
891 also George Washington was born on
February 22nd
1732 at least that's what we're told
however his family Bible says he was
born on February 11th
1731 slash two so which is it Mr I
cannot tell a lie
oh and don't even ask about
1752 in Russia 1752 looked pretty normal
but check out what the British Empire
was up to that year nothing really out
of the ordinary except Ember the second
was followed by the 14th were 11 days
just
deleted where' they go what happened
then it is time
to
question time and how the Earth moves
reconciling both of these things has led
to some pretty strange
things we all love time-lapse videos of
the Stars moving across the sky but
really we are the ones who are moving
tumbling Through the Universe on a giant
wet Rock vehicle called Earth with a
windshield called the sky as viewed from
above the North Pole we spin
counterclockwise West chases East I
always remember this by thinking of the
us as a weird main headed animal with
Texas and Florida legs running forward
but we don't just spin we also revolve
around the sun on a plane tilted
23.4 de relative to our spin it's kind
of nauseating at this scale but from
this perspective you can see that the
sun rising and setting is just the Earth
pointing you towards and then away from
the Sun this motion causes your Sunrise
your noon the moment when the sun is
highest in your sky before your Sunset
to more closely investigate this
movement let's talk about
meridians you are on one at this very

line of longitude as opposed to the
horizontal lines that lay flat when
North or South is up that we call
flatitude
or actually latitude the sun is highest
in the sky to you your noon when your
Meridian is pointed right at the Sun a
cool thing happens at this moment all
Shadows around you point directly
towards one of Earth's poles
unless you're on the subsolar point the
subsolar point is the point on Earth's
surface directly below the Sun It's
Always Somewhere you can check its
current location online links as always
in the description on The subsolar Point
Shadows Fall straight down so they can
easily disappear twice a year the
subsolar point crosses over Hawaii the
only place in in the US where it hits
land and when it does it is called
lahina noon meaning cruel Sun straight
vertical objects look unnatural during
this brief time like they don't belong
as if they were photoshopped in without
regard for reality in Honolulu a
sculpture by isamu naguchi called
skygate casts a twisted Shadow all day
every day except during lahina noon when
its shadow is a perfect
Circle you may not live in a place where
the sun ever appears directly overhead
but once every earth rotation the
