A nice video on the technical details of machine learning starting with neural networks in 2012. The breakthrough came in 2015 with Residual Networks, developed by four Chinese men who were working for Microsoft in Beijing. I fail to see how this is a "hack," but never mind that. Neural...

Progress. The geometric algebra people got it down to one. But I thought that was silly because in order to do anything useful you have to unpack it.

Maxwell originally had about 20 equations using quaternions. That went out of style.

Isn't She Lovely

So they are accelerating in a vacuum. Superman does it so why not. Mark is presumably accelerating as much as he is able. When entangled with Conquest there is more mass so acceleration is less. We'll assume there is a time limit on this : Mark can only control Conquest's struggles to free...

The pair of Mark with struggling Conquest would be less aerodynamic than Mark flying all by himself, producing all sorts of drag. This reduces Mark's maximum velocity and Mark has to expend energy to overcome the drag. However it is true that the increased mass would increase momentum and...

So what if a neutron star undergoes the anti matter transformation. The core of a neutron star contains a few percent of protons and electrons. This makes for the highest density of protons and electrons in the Universe. The electron-proton distance is ten thousand times less than in the case...

Does Mark smash Conquest into the ground by flying like Superman? Or does Mark lift Conquest whilst standing on the ground then slam him? In case one the mass of Conquest decreases Mark's velocity while leaving the amount of kinetic energy the same. While both would be affected by the...

This is the theme song for a TV show. Does any other nation have stuff like this? It was about a band of high school girls who form a rock band. This inspired real girls to do the same while thinking this level of difficulty was normal. They grew up and today Japanese women dominate the...

I crudely calculated the energy released if a hydrogen atom were instantly converted to antimatter. 4 * 10^-26 joules. If this were to occur in the same instant to all atoms on the planet Jupiter there would be no measurable effect. So it appears this radical transformation would be...

Mr. Bolden was known for playing the trumpet extremely loudly, an advantage in the days before electronic amplification but at sacrifice of musical tone. Playing in the fairgrounds he could be heard miles away in New Orleans. He was possibly the first jazz artist. He developed schizophrenia...

There would be an instant change to repellant force followed very shortly by a reversion to attractive force. Would the positron fly off into space? I would expect it wouldn't have enough time to do that. Would a photon be emitted? Two? If so then you have energy coming out of nowhere. If...

It's called science fiction. If you aren't interested then you aren't interested, yes?
