Dale's latest activity

It is not generally true that the E field in a conductor is 0. It is only true in the electrostatic limit where the current density is zero.

There has been an influx of math and physics people into a number of biological sub-fields. Areas like genetics (like Watson and Crick...

I guess I took the diagram too literally then. In this case I agree with @Dale that the mechanism proposed by @jbriggs444 is quite...

I'm really glad you posted this and shared the quote from @jbriggs444. I did read his post, but maybe, since I was reading a lot of...

This sounds like the most likely hypothesis. It could be tested by comparing a bag with trapped air and a bag with all air removed. It...

Here is some of a special issue of Genetics of articles using math: Many of the articles are open access. They can be seen here...

Investigating the history of math or the philosophy of math is not exactly the same as using math. A more convincing reference would...

The idea is that with water on all sides, the clay is effectively sealed. Any air in the lump of clay cannot escape without forming a...

Here are some slides from Vokos' talk at https://www.aapt.org/doorway/TGRU/...

I'm not sure what the best tools are to treat the relativity of simultaneity. I find space-time diagrams (Minkowskii diagrams)...

If you have a sous vide you could test temperature dependence. Room temperature and residential water temperature can fluctuate. I don’t...

Here is the arxiv version Student understanding of time in special relativity: simultaneity and reference frames Rachel E. Scherr, Peter...

Could it be a temperature difference? 18” of water is about 0.05 atmospheres, so it is some pressure but not a lot.

In my experience this definitely takes a great deal of time and effort. Reading something like Spacetime Physics by Taylor and Wheeler...

You seem to be stuck on the idea that "time slows down". One can ask "Slows down relative to what? To me, your words suggest you...
