Be singularly fashionable with this sharp two-sided shirt.
The front design is a graphic representation of a black hole
the back is a humorous look at Maxwell's equations of light.
Black
Size S, L,XL
FRONT
Depicts the curvature space-time caused by the immense gravitational
attraction of a black hole
The equation shown calculates the critical radius (Schwarzschild radius)
of a black hole -the distance from the center of a collapsed star at
which its escaped velocity equals the speed of light.
Anything that gets within this radius,even a passing beam of light is
trapped forever.
This also stops any radiation escaping from the star itself,hence the
name black hole
Rs=the Schwarzschild radius
M= the mass of a star in solar masses(our Sun is one solar
mass)
G=the gravitational constant
c2 =the speed of light squared
BACK
Maxwell's equations of light
He was the first scientist to propose that light was actually a wave
made of electric and magnetic fields
Published in 1873 ,these four equations unify electricity and magnetism
and therefore describe the behaviour of light and electromagnetic
radiation
