renormalize's latest activity

That's also the reason that hot and cold spots on the order of that size exist inside the cavity of your microwave oven, which operates...

Bluetooth operates at about 2.4 GHz, with a wavelength of 125mm, or 5". You can expect multipath reflections which can give some peaks...

But are there any unbound states of the harmonic oscillator, or more generally of any potential of the form ##V(r)=k\,r^n## where...

Here's a nice review paper from 2023: Proton decay. You can probably find more up-to-date info by using Google Scholar to search for...

Your diagram needs a better looking wench.:wink:

That's not true in general. The attractive force of a harmonic oscillator has positive energy. Attractive central-potentials of the form...

How naive are you? I have personally reported to the forum mentors dozens of spam posts here selling scientific instrumentation...

But the 1972 picture is doubtless a film photo while the one from 2026 was most likely captured by a digital sensor. Can you cite...

Noooo. The 1972 pic was taken of the sunward side of the Earth - almost full sun. The 2026 pic was taken of the Earth's night side -...

Must be a Rorschach test! I see Africa, the Middle East and Madagascar in 1972 and Australia(?) in 2026.

I boosted the brightness and contrast a bit on your Artemis photo and voilà! Earth in 2026 actually looks as good or even better than it...

Your step:$$\lim_{x\to0}\frac{\frac{\tan(\tan x)}{tan(x)}\cdot\frac{1}{sin(x)}-\frac{\sin(\sin...

Can you cite a credible textbook reference that supports those claims?

So you assert that the metals mercury at room temperature and aluminum at 660°C are not soft materials?

Further posts in this thread should be pointers to other level-appropriate sources of accurate information.
