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.

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
