renormalize's latest activity

This is indeed a bit strange. It is an Austrian address, and the pdf says about the author University of Applied Arts Vienna, more...

Is this material available anywhere else? Regarding your link, my security software states: "Your connection to this web page is not...

There is. If you practice Einstein's summation convention a little, where repeated indices imply summation:$$A_iB_i:=\sum_{i=x,y,z} A_i...

Indeed

A tragedy indeed. And I must say I did a double-take at the birth- and death-dates. I hadn't before encountered Buddhist Era (BE) dates...

No, the two expressions ##\nabla\cdot\vec{E}## and ##\vec{E}\cdot\nabla## are very different. The first is simply the scalar quantity...

A while ago @bhobba pointed to an interesting paper by T Padmanabhan: "Obtaining the Non-relativistic Quantum Mechanics from Quantum...

Your toilet definitely appears to be siphonic: (from...

This is a very interesting discussion. Do either of you know of references that compare and contrast standard (non-relativistic) QM with...

I think the first alternative is better, but it depends on how you define ΔE and Δt. For ## \Delta t ## it is customary to use the...

At what value of ##x## does the Dirac delta function ##\delta\left(x\right)## equal to ##1\,##?

@mathman100000, this is a personal opinion. While there is a non-zero percentage that this is the case, it is far more likely that...

Having not read this paper I offer no opinion on its physics content. But with regard to its "seriosity" I will just point out that...

The PCB cavity looks like a through at DC so when driven by coax it transmits 100% of the DC signal. But a hollow cavity coupled with...

Let's look at a real-world example consisting of a resonant printed circuit board (PCB) structure driven by coax connectors...
