## Is it more than a simple technical device that we have at infinite axioms in ZFC?

Take the axiom of Comprehension that was introduced by Zermelo. This, as usually stated has one instance for every single formula. Presumably this is to contain the axiom within first-order logic.

## How to calculate extent of Sequence similarity

I had a problem that I was wondering if it could be solved by one of the techniques/algorithms used in bioinformatics to give the extent of similarity. I have a Problem Statement: we have a senso...

## How do TLR1/TLR2 activate the MyD88 dependent pathway

Recently, I've been reading about the MyD88 dependent signalling pathway, with particular reference to its activation in Macrophages and other cells of the immune system on recognition of a pathog

## Is that a correct usage of present perfect?

What do you think about this sentence? Do you have bought the lesson book? Is that a correct usage of "Do you have bought"? Or should I say "Did you buy"?

## industry problems or industrial problems

Should we say industry problems or industrial problems? Which is incorrect? or maybe each of them has specific meaning, then what is that meaning? I myself think the "industry problems" m

## Electric field near a conducting surface vs. sheet of charge

I know perfectly well how to derive the magnitude of the electric field near a conductor, $$E = \frac{\sigma}{\varepsilon_0}$$ and near a sheet of charge, $$E = \frac{\sigma}{2\varepsilon_0} .$$ ...

## Power due to dipole radiation and time reversal symmetry in classical E&M

The dipole formula for the power loss emitted by a time varying electric dipole is (in natural units) $P = \frac{\dot d_i^2}{6 \pi}$. This is clearly even under time reversal symmetry $T$, but a p...

## Conducting surface inside conducting surface

Let's say there's a closed conducting surface. Then by Gauss's Law the E field bound by the surface must equal the charge inside. There's no charge inside, so the E field cancels. This
