Any light you see is made up of a collection of one or more photons propagating through space as electromagnetic waves.
a photon, or quantum, of light is produced whenever an electron in a higher-than-normal orbit falls back to its normal orbit, emitting a packet of energy with very specific characteristics.
the photon has a frequency, or color, that exactly matches the distance the electron falls.
the photoelectric effect was discovered in 1887 by heinrich hertz and explained by albert einstein in work for which he received the nobel prize.
the energies of photons range from high-energy gamma rays and x-rays to low-energy infrared and radio waves, though all travel at the speed of light.
in 1900, max planck, a german theoretical physicist, found that heat radiation is emitted and absorbed in distinct units, which he called quanta. he received the 1918 nobel prize in physics.
the energy of a photon equals the frequency of the radiation multiplied by planck's constant, a value of 6.626 x 10-34 joule-seconds, represented by the symbol “h” and equal to the energy of a quantum of electromagnetic radiation divided by the radiation frequency.
electromagnetic radiation can be described in terms of a stream of photons.
photons are the smallest unit of light/electromagnetic energy and generally regarded as particles with zero mass and no electric charge.
sometimes the amount of energy a photon has makes it behave more like a wave than a particle. this is called the “wave-particle duality” of light.
there are three types of photons: shadow photons, global photons, and caustic photons.
gilbert lewis coined the term photon in 1926. .

There are more stars in the universe then grains of sand in all of earths beaches, think about that for a second 🤭, have a nice week guys! 🚀

"when i was a boy, some people regarded the statement "the sky is the limit" as a positive affirmation, implying anything is possible. the truth is the sky is not the limit...i know the sky is not the limit, because there are footprints on the moon- and i made some of them!" - buzz aldrin (from no dream is too high)

this painting of the moon is the most magical place i've gotten to work on so far. i cannot get away from the beauty of creation, its enormity, its intensity. i am in awe. this week at the library i picked up eight books about the moon, nasa and the apollo missions to indulge this fascination...they are all amazing. the quote above is from one of the books, and makes me dream bigger. i want to live my whole live in marvel even if my feet always stay on the ground, i can spend hours on the moon with just a paintbrush and some watercolors.

This is how it would look from our point of view if those stars replaced our beloved sun ☀️
