Who was the first scientist to propose that an object could emit only certain amounts of energy?

Around 1774 Horace Bénédict de Saussure showed that non-luminous warm objects emit infrared heat and used a glass-topped insulated box to trap and measure heat from sunlight. [15] [16] The physicist Claude Pouillet proposed in 1838 that water vapour and carbon dioxide might trap infrared and warm the atmosphere but there was still no experimental evidence of these gases absorbing heat from thermal …

His mathematical theory now called Maxwell’s equations predicted that a coupled electric and magnetic field could travel through space as an “electromagnetic wave”.Maxwell proposed that light consisted of electromagnetic waves of very short wavelength.

Discovery. The first pulsar was observed on November 28 1967 by Jocelyn Bell Burnell and Antony Hewish. They observed pulses separated by 1.33 seconds that originated from the same location in the sky and kept to sidereal time.In looking for explanations for the pulses the short period of the pulses eliminated most astrop…
