Planck was as steeped in traditional physics as his colleagues, but he had an open mind. The older way wasn't working. So he changed one basic assumption: energy, instead of being continuous ...

On October 19, 1900, Planck presented a new radiation law. In its derivation he set aside his reservations about the Boltzmann method and introduced “energy elements” of a specific size that we today ...

Scientists say Vallis Schrödinger and Vallis Planck—dramatic trenches near the lunar south pole—were carved in a blast that ...

Planck tried a mathematical trick. He presumed that the light wasn't really a continuous wave as everyone assumed, but perhaps could exist with only specific amounts, or "quanta," of energy.

That’s pretty much all you need for instruments to determine Planck’s constant to a decent ... LED from the somewhat grandly named “photon energy array” and provide a way to adjust and ...

But the distribution of energy radiated in "real life" never matched up with the predictions of classical physics. Several distinguished physicists had created complex equations trying to work it out, ...
