what is time a deceptively simple
question yet it is the key to
understanding relativity which is also
the reason my hair is going great when
we describe motion we do so as a
function of time 10 m/s 100 miles per
hour but the mathematical description of
velocity is not unless we can define
time each time universal in other words
is there an audible tick-tock throughout
the galaxy a master clock so to speak
forging ahead like Mozart’s metronome
the answer my friends is no time is not
absolute in fact for us the living
physicists the distinction between the
past present and future is but a
stubborn illusion
a lot to consider
I know I know but understanding time is
essential to understand relativity now I
want you all to close your eyes not to
worry I don’t bite but I am on the
lookout for you Ted go on close your
eyes fully grasp the idea of time we
must take a step back and ask what is
light journey with me
light travels from the Sun to the earth
who says yes now as your age I wanted to
know how can something light travel
through not in space let us isolate a
light beam and travel alongside it with
the – go faster
you dare we
ah
what is time Einstein my god I wasn’t
sitting so I was thinking no really
about what exactly
the secrets of the cosmos I suppose I
suggest you think about trigonometry
instead with your eyes open and heat up
law of sines and cosines
[Music]
[Music]
differences between her I’m Stein are
you still too busy contemplating the
secrets of the cosmos to solve this
equation oh no sir I’ve already solved
it please now on what offends your mere
puzzles also respect of the clock Foley
that is not an objective reason out
natural log of a constant multiplied by
x equals the natural log of 1 plus B
Square and since B equals y over X
matches with the final function x
squared plus y squared minus C X cubed
equals skill and speaking truthfully
your mere presence boils my respect for
the future of Prussian mathematics our
