This is true not only for sand but also for wet paper or fabrics. It all has to do with the phenomenon of scattering, that is, the number of collisions that the light beam undergoes before surfacing again.

The answer was found by Scottish distilleries in 1761. Wood was expensive, and to cut fuel costs, they turned to chemist Joseph Black.

The main difference is that white ones are less dazzling and offer better diffusion , of course, at the cost of greater light absorption...

In this way Einstein justified the reader of "Autobiographical Notes" - which, with black humor, he said were his obituary - that he was confronted with a little biographical book full of mathematical formulas and complicated concepts. Here, as in many other things, Albert Einstein was a peculiar man: "But I am like that, and I cannot be otherwise." For this reason, in his "Notes" he recounted the fascination he felt the day his father showed him a compass, but he did not say that his name was Hermann.

The most remote point or distance to which the human eye is able to focus is at infinity, where in theory our sight would...

"Quantum mechanics would allow you to make your income tax return in a second" This 35-year-old researcher born in Manresa is one of the great experts in quantum mechanics. Professor of Theoretical Physics at the Austrian University of Innsbruck, he is currently working on the creation of a quantum computer and on the Theory of Entanglement.

This question obeys a simple law of physics. White bread reflects more radiation than black bread, precisely because it has a less dark appearance....
