is everybody ready for an astronomy lesson this will be the second largest
lesson this will be the second largest
lesson this will be the second largest class I’ve taught the first one I’ll
class I’ve taught the first one I’ll
class I’ve taught the first one I’ll talk to you about today I’ve titled the
talk to you about today I’ve titled the
talk to you about today I’ve titled the talk 121 seconds because that’s how long
talk 121 seconds because that’s how long
talk 121 seconds because that’s how long the eclipse lasted at Furman well let me
the eclipse lasted at Furman well let me
the eclipse lasted at Furman well let me get into a little bit more what else can
get into a little bit more what else can
get into a little bit more what else can happen in 101 121 seconds well let’s
happen in 101 121 seconds well let’s
happen in 101 121 seconds well let’s think I can make a bowl of oatmeal I can
think I can make a bowl of oatmeal I can
think I can make a bowl of oatmeal I can pop a bag of popcorn on a more nerdy
pop a bag of popcorn on a more nerdy
pop a bag of popcorn on a more nerdy side you can actually bounce radar from
side you can actually bounce radar from
side you can actually bounce radar from the Earth to Venus at the speed of light
the Earth to Venus at the speed of light
the Earth to Venus at the speed of light and it takes about two minutes yeah of
and it takes about two minutes yeah of
and it takes about two minutes yeah of course there are certainly things that
course there are certainly things that
course there are certainly things that are much shorter lives yeah for example
are much shorter lives yeah for example
are much shorter lives yeah for example 121 seconds is an eternity to Higgs
121 seconds is an eternity to Higgs
121 seconds is an eternity to Higgs boson in the Large Hadron Collider

subatomic particles it was very
subatomic particles it was very difficult to find that object because it
difficult to find that object because it
difficult to find that object because it didn’t last very long but 121 seconds is
didn’t last very long but 121 seconds is
didn’t last very long but 121 seconds is nothing compared to basically the
nothing compared to basically the
nothing compared to basically the basically the breath and of time and

what 121 seconds means to me and what it
what 121 seconds means to me and what it meant for all of us that were around
meant for all of us that were around
meant for all of us that were around that very hot summer day on August 21st
that very hot summer day on August 21st
that very hot summer day on August 21st 2017 once that was the day of the great
2017 once that was the day of the great
2017 once that was the day of the great American solar eclipse it was a
American solar eclipse it was a
American solar eclipse it was a coast-to-coast solar eclipse that travel
coast-to-coast solar eclipse that travel
coast-to-coast solar eclipse that travel that basically the shadow of the moon
that basically the shadow of the moon
that basically the shadow of the moon went from basically the Pacific coast in
went from basically the Pacific coast in
went from basically the Pacific coast in Oregon across the United States to the
Oregon across the United States to the
Oregon across the United States to the Atlantic coast of Charleston it took
Atlantic coast of Charleston it took
Atlantic coast of Charleston it took only 90 minutes to cross the United
only 90 minutes to cross the United
only 90 minutes to cross the United States but the thing is it crossed right
States but the thing is it crossed right
States but the thing is it crossed right over Furman and we knew it was going to
over Furman and we knew it was going to
over Furman and we knew it was going to cross over from in years ago I was
cross over from in years ago I was
cross over from in years ago I was employed in 1999 and I knew it was gonna
employed in 1999 and I knew it was gonna
employed in 1999 and I knew it was gonna be here we’ll talk a little bit about
be here we’ll talk a little bit about
be here we’ll talk a little bit about how I knew that
how I knew that
how I knew that well the thing is there’s many steps
well the thing is there’s many steps
well the thing is there’s many steps that have to happen for an eclipse to
that have to happen for an eclipse to
that have to happen for an eclipse to happen
happen
happen and among those one you have to have an
and among those one you have to have an
and among those one you have to have an alignment of the Sun the moon and the
alignment of the Sun the moon and the
alignment of the Sun the moon and the earth a syzygy they call it in which the
earth a syzygy they call it in which the
earth a syzygy they call it in which the basically the moon shadow strikes the
basically the moon shadow strikes the
basically the moon shadow strikes the earth but that can only happen every
earth but that can only happen every
earth but that can only happen every once in a while the moon’s orbit is
once in a while the moon’s orbit is
once in a while the moon’s orbit is tilted with respect to the orbit of the
tilted with respect to the orbit of the
tilted with respect to the orbit of the Sun of the earth around the Sun by about
Sun of the earth around the Sun by about
Sun of the earth around the Sun by about five degrees so we don’t get eclipses
five degrees so we don’t get eclipses
five degrees so we don’t get eclipses every every month we don’t get a solar
every every month we don’t get a solar
every every month we don’t get a solar eclipse every month we don’t get a lunar
eclipse every month we don’t get a lunar
eclipse every month we don’t get a lunar eclipse every month because it misses
eclipse every month because it misses
eclipse every month because it misses the shadows miss all the time
the shadows miss all the time
the shadows miss all the time but there are two places in these
but there are two places in these
but there are two places in these orbital conjunctions that can occur
orbital conjunctions that can occur
orbital conjunctions that can occur they’re called nodes and if the moon
they’re called nodes and if the moon
they’re called nodes and if the moon happens to be new phase on one of these
happens to be new phase on one of these
happens to be new phase on one of these nodes you get a solar eclipse the second
nodes you get a solar eclipse the second
nodes you get a solar eclipse the second thing that has to happen is well the
thing that has to happen is well the
thing that has to happen is well the shadow actually has to reach the earth
shadow actually has to reach the earth
shadow actually has to reach the earth and the moon’s orbit is not circular
and the moon’s orbit is not circular
and the moon’s orbit is not circular it’s elliptical sometimes a little
it’s elliptical sometimes a little
it’s elliptical sometimes a little closer sometimes a little bit further
closer sometimes a little bit further
closer sometimes a little bit further away you’ve probably heard of super
away you’ve probably heard of super
away you’ve probably heard of super moons and that’s when the moon’s a
moons and that’s when the moon’s a
moons and that’s when the moon’s a little bit closer to Earth well if the
little bit closer to Earth well if the
little bit closer to Earth well if the moon’s too far its shadow can’t actually
moon’s too far its shadow can’t actually
moon’s too far its shadow can’t actually touch the earth and you end up getting a
touch the earth and you end up getting a
touch the earth and you end up getting a different kind of apparition you get
different kind of apparition you get
different kind of apparition you get what’s called an annular eclipse where a
what’s called an annular eclipse where a
what’s called an annular eclipse where a ring of sunlight ends up going around
ring of sunlight ends up going around
ring of sunlight ends up going around the moon and I’ve actually seen one of
the moon and I’ve actually seen one of
the moon and I’ve actually seen one of these they were quite nice but I’ve
these they were quite nice but I’ve
these they were quite nice but I’ve never actually saw a total eclipse until
never actually saw a total eclipse until
never actually saw a total eclipse until last year the third thing is you have to
last year the third thing is you have to
last year the third thing is you have to be at the right place at the right time
be at the right place at the right time
be at the right place at the right time now for those of us who are fortunate to
now for those of us who are fortunate to
now for those of us who are fortunate to live underneath the Eclipse path or have
live underneath the Eclipse path or have
live underneath the Eclipse path or have the means to actually travel to it
the means to actually travel to it
the means to actually travel to it that’s great you actually get to see an
that’s great you actually get to see an
that’s great you actually get to see an amazing thing and for most Americans a
amazing thing and for most Americans a
amazing thing and for most Americans a hundred million people could actually
hundred million people could actually
hundred million people could actually drive and get to see one of these that’s
drive and get to see one of these that’s
drive and get to see one of these that’s why we call it the Great American solar
why we call it the Great American solar
why we call it the Great American solar eclipse the shadow itself is only 70
eclipse the shadow itself is only 70
eclipse the shadow itself is only 70 miles across so if you’re here in
miles across so if you’re here in
miles across so if you’re here in Greenville you got to see it for
Greenville you got to see it for
Greenville you got to see it for 21 seconds if you happen to be in say
21 seconds if you happen to be in say
21 seconds if you happen to be in say they Anderson jockey lot you could see
they Anderson jockey lot you could see
they Anderson jockey lot you could see it for 158 seconds and the shadow itself
it for 158 seconds and the shadow itself
it for 158 seconds and the shadow itself is traveling across the United States at
is traveling across the United States at
is traveling across the United States at 90 minutes across the United States
90 minutes across the United States
90 minutes across the United States means it’s moving at 2200 miles per hour
means it’s moving at 2200 miles per hour
means it’s moving at 2200 miles per hour that’s faster than Iike mercial air
