- What does $QAQ^{-1}$ actually mean? - Mathematics Stack Exchange
1 $\begingroup$ When one thinks of matrix products like that, it's helpful to remember that matrices, unlike vectors, have two sets of bases: one for the domain and one for the range Thinking of applying a vector on to the right, we get that the transformation "unrotates" the vector, applies the original transformation in the original basis
- 1. 0Gpbs是千兆网吗？为什么下载速度只有10MB s? - 知乎
1 Gbps=1000 Mb s=1000 8 MB s=125 MB s，这是和您的测试设备相连的1 Gbps物理带宽下的极速。 关键点是1 B（byte）=8 b（bit）。 实际下载速度还取决于下载源的限制、出口的物理链路和运营商的限制。 例如，休想只交百兆宽带的钱还享受千兆宽带的待遇。

- abstract algebra - Prove that 1+1=2 - Mathematics Stack Exchange
The main reason that it takes so long to get to $1+1=2$ is that Principia Mathematica starts from almost nothing, and works its way up in very tiny, incremental steps The work of G Peano shows that it's not hard to produce a useful set of axioms that can prove 1+1=2 much more easily than Whitehead and Russell do
