Examples

  • Because of the quantal coarseness of matter, nothing made of it, machine or brain, can process information faster than about 10^47 bits/g/sec.

  • But there was a problem: The same reasoning that implied a quantal structure for radiation in the Wien regime also implied that, outside that regime, the assumed mutual independence of photons must fail.

  • So, so we got the sense of what quantal field theory is, is that a big leap of, of an idea that particles are fluctuations in the field?

  • A GLM can be used to describe the relationship between the dose and the quantal response at the end of the assay: g(pis) = as + ? log10(di gpiT) = aT + ? log10(di)

  • The quantal behavior of photons is evident when they are emitted as individual packets of energy.

  • At the atomic level, matter exhibits quantal properties that differ significantly from classical physics.

Morphology

quantal = quantum (transparent) = quantum + al

The adjective is formed directly from 'quantum' with the common adjectival suffix '-al', so the meaning is readily recoverable.

Etymology

Quantal comes from quantum, which goes back to a Latin root meaning 'how much', and you can see the same root in quantity. In science quantum came to mean a small, separate 'amount', so quantal describes things that happen only in separate steps, not in a smooth way.
