  • At the dawn of the twentieth century, German physicist Max Planck postulated that energy was radiated in tiny, discrete units, which he called quanta.


  • The first: Energy is not a continuous stream, but actually a stream of discrete, if very small, units that we call quanta.

  • (The increment is to ensure the price moves up in quanta larger than a penny.)

  • And the German physicist Max Planck made one of the discoveries that would shape the century: that atoms emit radiations of energy in bursts he called quanta.

    American Sketches

  • Max K.E.L. Planck put forward his radically new idea that the radiated energy could only be emitted in quanta, i.e. portions that had a certain definite value, larger for the short wavelengths than for the long ones (equal to a constant times the frequency for each quantum).

  • Planck suggested that radiant energy exists only in discrete packages that he called quanta.


  • If the atom, at the same time as it receives from without a quantum of light, emits a quantum of light of a different magnitude, and if the difference between these two quanta is identical with the quantum of light which is bound or released when an electron passes from one path to another, the quantum of light coming from without is absorbed.

  • This was a new concept, and it became known as quanta, since it suggested energy travels at

  • The idea that those invisible units of energy called quanta react according to the expectations of the observor?

    back to paper bags

  • Again, some things are called quanta in virtue of their own nature, others incidentally; e.g. the line is a quantum by its own nature, the musical is one incidentally.
