that's about 300 million homes that
Santa's got to visit all around the
world in one night presumably to
minimize his chances of being spotted
he's going to try and make his whole
trip under the C of
[Music]
Darkness but Santa has got one uh trick
up his sleeve because he can use the
fact that the world is turning to his
Advantage let's assume he's going to
start in the East so probably all the
way in Eastern Russia almost by the DAT
line and he's going to travel Westward
he's moving with the night which can add
on an additional 24 hours to his total
time so that gives him a total of 32
hours to make it all the way around the
world and deliver

presents houses aren't just sort of
equally distributed around the world we
live in cities and towns and we're sort
of clustered but then other places folks
that sort of live out in the country
Santa's got to travel some distance to
go from house to
[Music]
house you know fish is and whal they
don't get any gifts from Santa we can
use a mathematical problem called the
traveling salesman
problem it's exactly the same setup it's
a a Salesman that's traveling around
different houses and wants to do so as
efficiently as possible
[Music]
now that is quite a lot slower than the
speed of light but substantially more
than the speed of sound if he's
traveling at Super Sonic
Speed where is the sonic boom like that
would wake up all the kids and they'd
like stop Sani in tracks NASA themselves
has said that that it May well be
possible to build a jet that can get up
to supersonic speeds without making a
boom I mean if NASA can do it well Santa
can
[Music]
surely Santa could have a NASA style
heat shield that protects all of the
reindeer from those aerodynamic forces
you just don't know what sort of amazing
objects he's using to to pull off these
kinds of speeds
