Sect. 7.4 - TTU Physics
... increased with u. They talked of u dependent “Relativistic” mass m & “rest mass” m0. Then, (1) was written using the classical definition as p = mu, but m was Relativistic & had the form: m = m0[1 - (u2/c2)]-½ • It’s conventional now to consider the mass m as the same as it is in Newtonian mechanics ...

Planck`s Hypothesis - University of Toronto Physics
... Planck’s Hypothesis Planck’s “quantum hypothesis”: maybe when a body emits or absorbs light of frequency f, it can’t emit any old amount of energy it likes, because there is some “special energy”: it emits energy in “steps” of E=hf. Energy per frequency: Planck’s constant: h = 6.6 • 10-34 J s ...

Strings as hadrons
... We all know that Science is full of surprising twists. But the discovery of string theory was particularly serendipitous. The theory grew out of attempts in the 1960s to describe the interactions of hadrons (particles that contain quarks such as the proton and neutron). This was a problem that had n ...
