cynar , to Men's Liberation in Men Need a New Narrative. The Future of U.S. Democracy Depends on It

The left is far less monolithic than the right. It was a sub-subset of the left, a percentage of feminists were/are anti male. Unfortunately, they were not called out for this, and so got very loud about it. This coloured the message from general left leaning sources.

Growing up, there was a lot of "men are bad/evil" and that we needed to make it up to women. A lot of this pressure came from left leaning sources.

Thankfully, I managed to avoid getting drawn into the right leaning backlash to this.

Can you point out which privilege he is losing (that everyone shouldn't have)?

That’s why I said space-time, not just space. Generally worked with in the form of [X,Y,Z,iT] to make them all behave space like. Basically 2 4D positions become the same position. The fact that the 2 positions are displaced in time is almost incidental. The rules for the transformation however still have to collapse down to the same underlying measurements, so it’s a lot more complex than 2 arbitrarily points.

A minor nit pick. It’s worth noting that increasing mass is an inaccurate view. It works in the simple examples, but can cause confusion down the line.

Instead, an additional term is introduced. This term, while it could be combined with the mass, is actually a vector, not a scalar. It has both value and direction, not just value. This turns your relativistic mass into a vector. Your mass changes, depending on the direction of the force acting on it! Keeping it as a separate vector can improve both calculations and comprehension, since comparable terms appear elsewhere (namely with time dilation and length contraction).

It’s also worth noting that it also experiences zero distance. If you’re willing to tie your brain in knots, a photon doesn’t exist. Instead, space-time flexes so that 1 point touches another, momentarily. Energy is transferred, and space-time recoils back. That flex would be mathematically identical to a photon traversing the intervening space-time.

There’s a reason we use photons however. Such twisted space is effectively impossible for our brains to usefully comprehend.

The combination of the infinite improbability drive leaking, and the SEP (somebody else’s problem) field is amazing. It provides an in-universe explanation for the various weird and unlikely things that happen.

If you want to get pedantic, as far as photons are concerned, photons don’t exist. At C time dilation hits infinity, while length contraction approaches zero. Therefore photons travel zero distance and experience zero time. Therefore, from a photon’s perspective, they don’t exist!

I’m fairly sure microwaves float in space. I don’t think there are completely different laws of physics, just for microwaves. A microwave in a bistro however…

cynar , to xkcd in xkcd #217: e to the pi Minus pi (31 Jan 2007)

I did a physics degree. The start is the sort of random stuff that would come up down the pub (in the evenings). I could easily see a conversation like this happening (at least the start).

cynar , to Home Improvement in How to build fire protective battery charger enclosure?

A fairly common solution is military ammo boxes. They are designed to contain ammo cooking off, as well as protecting their content from fire. They therefore deal with battery fires fine. Just make sure there isn’t anything too flammable close to them, or above them. Any fire that happens will be directed upwards. Just line them with something not electrically conductive.

FYI, never put water on a battery fire. The water can react and make the fire worse. Instead use sand. It reduces flames and acts as a heat dump for the generated heat.

A good setup would be an ammo can for each large battery on a none flammable shelf (metal racking?), with nothing above it that can burn. A fire bucket of sand to hand, to control anything, and a smoke alarm will alert you to any issues as well. It’s overkill, most of the time, but good for peace of mind.

Part of the issue is compression. Most modern compression algorithms bias towards light areas of the picture. On high bandwidth streams, this is no issue. If the stream is highly compressed, the backs can become blocky and details are lost.

On top of this are suboptimal viewing conditions. Non HDR, background light, or poorly configured (or limited capability) screens. All of these punish the black parts of the image more than the bright.

I’ve got a degree in the subject, and I still often feel the same way. Quantum mechanics works outside what our savannah running monkey brains can handle. The best we can do is trust the maths and approximate as best we can. We’ll regularly break those approximations however, and get thoughly flummoxed.
