Alrighty, in this epic tome I introduced the Fourier series. I reviewed the Gibbs phenomena, when we have discontinuities the partial sums appear to sort of “overshoot” the function near the…

I’m no scientist so forgive me if my questions sound ridiculous.
If a micro black hole was actually created, would it have enough mass for it’s gravitational field to pull apart atoms and/or…

Here’s my favorite home-made self-resetting, bucket mouse trap. I think this is evil in its simplicity and elegance and laughed when I first saw it. Not being a human must be rough.

Hello Tommaso,
Thanks for nice postings. I have a naive question about the LHC beam. Looks like there is only one beam circulating right now, why do the detectors still see something? I thought the…
