Neutrinos, the smallest and lightest among the 12 elementary particles that make up the material world, are electrically neutral and travel at a speed close to that of light. Since the Big Bang, they have permeated the entire universe, generated in various phenomena, such as nuclear reactions i...
PM stands for particulate (微粒的)matter: the term for a mixture of solid particles (粒子)and liquid droplets in the air. Some particles are large or dark enough to be seen by our eyes. Others are so small that they can only(1) ___ (discover) with a microscope. These particles...
If all particles have the same color their draw order doesn't matter, but if they're different we need to sort them by distance to get the correct result. Note that when sorting based on distance particles might suddenly swap draw order due to position of view changes, like any ...
