    Chess is not segregated by gender. There are women’s tournaments and there are open tournaments. There are no men’s tournaments. Men are way overrepresented at all the open tournaments, but women do compete in all of them.

    Women’s representation is increasing at the top levels but it’s a gradual process. Judit Polgar and Hou Yifan (侯逸凡) are so far the only women to reach the top 100 players in the world and regularly compete with success at the top open tournaments.

    “For regulation” is a pretty weird take, but it is self regulating (in the absence of pollution from humans). When the ozone layer is thin, more UV gets through from the sun. UV from the sun ionizes O2 and splits it apart, creating oxygen free radicals which recombine and create ozone. Thus, less ozone leads to more ozone, hence self-regulation.







  • Inflation is a decrease in the value of money itself. If there’s a lot more money around today than there was yesterday, then money is less scarce than it was before. Scarcity is a major contributor to value by the theory of marginal utility:

    Suppose you have no first aid kit. Gaining a first aid kit gives you a tremendous amount of value! Now suppose you get a second first aid kit. Still valuable, but not as much as the first.

    Now you suppose you have a thousand first aid kits. What are you going to do with all of them? You can’t possibly use them all yourself! So you might as well give them away or try to sell them.

    First aid kits have declining marginal utility. Having way more than one gives you very little value relative to the value you gained from the first one. On the other hand, those first aid kits will have much more value for other people who don’t have one yet. Thus it’s better to distribute first aid kits than to hoard them.

    Most things work this way. One of the main exceptions is money itself. The more money you have, the more you can do with it! Of course, at large enough levels of wealth, what you can do for yourself personally (buy food, clothes, shelter, entertainment) shows the same diminishing marginal utility: being able to afford a steak dinner every day is one thing, but nobody is going to eat 10,000 steak dinners every day!

    On the other hand, the other use of money is to hold power over others, and there’s no limit to that, unfortunately. The biggest problem is the existence of people who actually want that!





  • If the hot water drops in temperature

    There’s not much reason for that to happen unless the building’s water heater has failed or is undersized. I have had that happen once in the decades I’ve lived at this house and it was a simple matter of turning the handle up a bit hotter.

    Otherwise, the effect thing you described (the mixer lowering the pressure to maintain a constant output temperature, assuming the hot water supply is constant temperature) works just fine. I have never had the water suddenly become unexpectedly hot or cold after the initial warmup phase.
