The problem with a two-stage system is the dew point and the distinction between absolute and relative humidity. There are nice cool springs in northern Florida that pump out water at a brisk 72 degrees F. Jump in them and you will cool off rapidly. But they cannot cool anything below 72 F, and at 100% relative humidity that isn't pleasant. In a dry climate, you can use two-stage coolers to do all the work. In a wetter climate, you can use them to reduce the energy demand of regular air conditioners, but you still can't use them to do all the work of making pleasant indoor air. You have to cut the relative humidity somehow, and that requires lower temperatures.

This is somewhat beside the point you are making, but the ubiquity of smartphones has greatly diminished this particular problem. Show the driver your destination on Google Maps on your phone and they will immediately intuit that you're watching.

I'm perfectly fine with them flying first class, but commercial it should be. Of course, that's what most of the 1% do - private jets are more like the 0.01%.

Also, following its advice will make you lose weight while you gorge yourself on delicious meat and sauces. Steak with Bearnaise vs rice cakes? It's literally sickening just how screwed up our nutrition advice is.

It's the frequency of an alternating current supply that causes fibrillation, not the current or the voltage. Cardioversion ("shocking the heart") is a blast of DC that works by making all the cells of the heart contract at once, so that the standard recovery period after a contraction is long enough to prevent the aberrant conduction from being propagated.

Let's just say it's one of the more entertaining fringe benefits of having "M.D." after your name.

Tires are almost silent on paved roads. Have someone put their car in neutral and turn the engine off as they roll down a hill toward you.

I'm a doctor, not a coder, but I did take C++-based CS101/102 in the late nineties, and I've played a little bit with the teach-yourself-Python courses. I'm fairly certain that I, having written next to zero code over the past 18 years, could write a piece of software in Python that cleanly accomplished everything the CS102 capstone project did, and in less than a week. Possibly in a day. Someone who knew their stuff could probably write it in thirty minutes.

Granted, that's partially missing the point - our project was meant to teach concepts like using doubly linked lists, how to export them into a file and read them back in, choice of algorithm, hashing functions, etc., not just banging out code. But in terms of something that would be useful to the average person who might want to write a snippet of code here and there to simplify their life, as opposed to someone who plans to make it their life's work, Python is amazing. Python lets students build useful programs right away because it can do the heavy lifting until they're ready to learn how the sausage is made. Maybe you'll spark curiosity in someone who would never have given it a shot. Maybe all you get is a person who has some appreciation for what writing software actually entails. Either way, aren't we all better off? The serious students are going to learn serious languages soon enough.

It's the Game of Thrones version of the Garden of Eden. Neckbeards like George R. R. Martin hate it because not enough people die horribly.

Stop what you're doing and watch Airplane! now.

I'm a fan of negative income tax. I'm marginally in favor of limited free tuition, although it's the sort of thing that encourages colleges to take the money and run, and it does little to alleviate the lack of income associated with being a full-time student. Single-payer universal health care (aka Medicare) is a fine concept, but the American people aren't willing to pay the taxes or cut the available services to make it work.

Risk and reward. Poor kids are much better off pursuing low-risk, moderate-reward strategies rather than high-risk, high-reward strategies, because in the event of failure, they don't have anything to fall back on. The children of the upper middle class can aim for the stars, knowing that they won't end up in the mud if they miss. Climbing the ladder takes generations.

Plenty of CRT's left in hospitals. Lots of patient monitors are old but still work exactly as intended, so there's no particular reason to replace them. They're not used in radiology, though.

Similar math problem: imagine the Earth is a perfect sphere, and you have a band of steel running around the equator. You need to roll an orange under this steel band. How much steel do you need to add? Less than a meter.

Creative potential? It would be intellectually trivial to build a 6502 or Z80 in Minecraft - a simple matter of translating logic to redstone. Doing so would be an enormous amount of work akin to creating such a processor out of discrete transistors, but the creativity involved would be minimal and mostly involved with problems like how to allow circuits to cross paths.
