You are on your computer on June 23rd, 2021 at 10:24:58 am, when it suddenly becomes bricked. Your electronic devices all fail, except for your newest technology. Why? This didn't happen to me, this is just a scenario I made up myself. It could've possibly happened in real life.

We have a quantity $a$ expressed in terms of two quantities $b $ and $c$ as $a = b/c$. It seems to me that there are two ways of estimating the error on $a$, the "physics" prescription and a "maths" one based on differentiation: According to "physics": $∆a/a = ∆b/b + ∆c/c$ Accordin...

I'm not talking about a water fountain, nor a power source. In Spanish, both of these things, which you can cook meat, pizza, etc. with, are called ‘fuente’ or ‘asadera’.

My friends sent me these pictures of a pool that has been abandoned for a long time, and we are curious about the reason behind the peculiar growth of algae in this pattern.

Specifically, what I was thinking is, can you use Mage Hand to tickle an enemy caster to try to make them lose concentration, or would that be considered attacking them?

For context, I heard that the Atiyah-Segal formalism of quantum field theory is equivalent to the traditional Wightman approach (at least within the scope of certain theories). However, I could not find a precise proof of this, only physical arguments.

$$\sum_{n=1}^{\infty} \frac{12}{(-5)^n}$$ If I rewrite this as $\sum_{n=1}^{\infty} 12(-\frac{1}{5})^n$ and then use the infinite geometric series formula, $\frac{a}{1-r}$ where $a = 12$ and $r = (-\frac{1}{5})$? I get 10 but since it starts at 0, I subtracted one from my total equation to get 9,...
