This scientist's namesake "epoch" is the first "10 to the minus 43" seconds of the universe's life, during which quantum gravity was significant.
This scientist's namesake "epoch" is the first "10 to the minus 43" seconds of the universe's life, during which quantum gravity was significant. He also names a system of maximally natural units. One quantity named for this man is the quantum of action. That quantity also appears in a law named for this man, which correctly described the blackbody spectrum and solved the "ultraviolet catastrophe". That same quantity is about "6.6 times 10 to the minus 34 Joule-seconds", and is the constant of proportionality relating the energy of a photon to its frequency, and is denoted by the letter h. For 10 points, name this founder of quantum theory.
