Son cigalong. Physicists prefer to use hermitian operators, while mathematicians are not biased towards hermitian operators. So for instance, while for mathematicians, the Lie algebra $\mathfrak {so} (n)$ consists of skew-adjoint matrices (with respect to the Euclidean inner product on $\mathbb {R}^n$), physicists prefer to multiply them Question: What is the fundamental group of the special orthogonal group $SO (n)$, $n>2$? Clarification: The answer usually given is: $\mathbb {Z}_2$. Apr 24, 2017 · Welcome to the language barrier between physicists and mathematicians. Six year from now, the old man's age will be only three times that his first born son. What's reputation and how do I get it? Instead, you can save this post to reference later.

How can this fact be used to show that the dimension of $SO(n)$ is $\\frac{n(n-1 Oct 19, 2019 · You'll need to complete a few actions and gain 15 reputation points before being able to upvote. I've found lots of different proofs that SO(n) is path connected, but I'm trying to understand one I found on Stillwell's book "Naive Lie Theory". Apr 24, 2017 · Welcome to the language barrier between physicists and mathematicians. In case this is the correct solution: Why does the probability change when the father specifies the birthday of a son? (does it actually change? A lot of answers/posts stated that the statement does matter) What I mean is: It is clear that (in case he has a son) his son is born on some day of the week.
