| | | | | Is this a record for a quantum computer A group of physicists in China have used a process called adiabatic computing to find the prime factors of the number 143, beating the previous record for a quantum computer of 21. However, there are doubts about the quantum nature of this method, and its potential ... | |

| | | It took me longer than necessary to understand how a rotation transform matrix rotates a vector through three-dimensional space. Not because it's a difficult concept but because it is often poorly explained in textbooks. Even the most explanatory book might derive the matrix for a rotation around one axis (e.g., x) but then present the other two matrices without showing their derivation. I'll explain my own understanding of their derivation in hopes that it will enlighten others that didn't catch on right away. | ||
