Photon–photon collision is theorized to be a fundamental means by which matter is generated in the universe, and it arises from Einstein's well-known equation E=mc 2. In fact, researchers have ...

"We can think of a photon being a fundamental excitation of ... imaginary components allows many of the difficult terms in the equation to cancel each other out. Provided all imaginary numbers ...

And now, thanks to a study published June 14 in Nature, we know that this organic chemical reaction is sensitive to the smallest quantity of light possible -- a single photon. The discovery ...

For photosynthesis, one photon is all it takes. Only a single particle of light is required to spark the first steps of the biological process that converts light into chemical energy, scientists ...

For the first time, researchers have observed the beginnings of photosynthesis, starting with a single photon. When light hits a plant's chloroplast — the sugar factory of the organelle world ...
