Yep. I can't remember the last time I chose to use Internet Explorer. I tried Project Spartan and it was all right, but on windows 10 I'm using Chrome. Works fine. Mozilla has blown for many, many years. And Chrome is starting to make the same mistakes.

And the OS I use those most? Android.

And so can a kid. It's been a long time ago (33 years) but when I was 11-12 I had a VERY good concept of programming and how to tinker. The internet wasn't really a thing in most households yet but I still knew computers, and most kids these days do too - even moreso.

And even though internet porn wasn't around back then - guess what - we still had porn as kids. Typically it was in the form of a magazine that some kid smuggled out of his dad's collection, so it certainly wasn't in the same volume, but every kid in the neighborhood seen it and almost all grew up to be perfectly normal adults.

This is all focused on nothing - by the time someone is aware enough about sex to try and access a website, they're GOING to be able to get that content.

You can use high powered lasers in short pulses to compress and heat a fuel pellet to achieve fusion. A particular approach called fast ignition requires a petawatt pulse. Given that the laser is named LFEX for "Laser for Fast Ignition Experiments", it is a good bet this is what it is for.

(My expertise in this is limited to having had an inkling which Wikipedia article to look in for the answer. Further input from real experts is welcome.)

Yes, I've been to those places because THC suppressed epileptic seizures I used to have (but only for several hours while it was in effect- it's an extremely expensive anticonvulsant and insurance doesn't cover it). Legal pot is particularly expensive. On what basis is pot cheaper that liquor or alcohol? Per "dose" (whatever that is for any of those three)? Cigarettes and liquor never tempted me to cut up my ATM card.
Plus, you can't survive on a 100% Taco Bell diet... just eating the pot would be more nutritious.

Not just a projected image, but anything it illuminates (so long as there is little other illumination to mess up the effect.)

If you've ever played with a normal monochrome laser in a dark room, you'll have seen how laser illumination makes things look speckly. Illuminating with this "white" laser will make superimposed speckly in three colours, with the locations of the speckles not coinciding, so it would be iridescent speckly.

Ohm's law: V=IR => I = V/R
Power dissipated in a resister: P=VI
Substituting for I from Ohm's law: P=V^2/R
So for a fixed voltage, you dissipate more energy with a low resistance. This would be what you're remembering from electronics. For example if you attempt to short high tension power lines with a dry kite string, the effect will be unimpressive. On the other hand if you short them with a solid copper bar, expect to be rained with molten copper.

However it is not the case that you're going to take a circuit and replace a Si device with a GaN device and leave everything else (including the voltage) unchanged. You design your circuit to provide voltages appropriate to the components it contains. If you need a certain current to make a device work, and can adjust the voltage to provide that current, then instead you get P=I^2R, and lowering R lowers the power dissipation.

What really keeps police busy is high school chemistry lessons. You know the one where you dissolve crystals in water, put in some electrodes and run a current through? That will get you charged with assault and battery.
