Is there an expected upper bound on the processing abilities of quantum computers? A computer can store some number $n$ of bits in memory, and it can perform some number $m$ of essential computational operations, such as addition or multiplication, and rewrite those bits to memory, per some unit of time, $t$. To give a rough estimate, consider a modern digital computer with ... (more) |

| Question | — |
In particle physics and string theory, what is mass? We commonly say that something has a weight, which is synonymous with a mass. Things have a weight because the force of gravity is relative to something’s mass. Subatomically, what is mass? There are massless particles, like photons. Is the concept of mass relegated to the smallest particles w... (more) |
