I am certainly no expert on the subject but I would suggest the following points as answers to your question.
1) Most (that I have heard of) plans for Land Value Tax do still include a smaller portion of property taxes. This does not completely solve the problem you pose but does ameliorate it a little.
2) Some of those infrastructure things are paid for via utility payments on utilities used. The 100 families in the apartment building will use much more water than a single family home. Some part of that money should be budgeted and used for improving the utilities available. That doesn't account for things like parks, fire department, etc. but does take up some of the slack.
3) lastly and most importantly those homes will be paying more than their fair share on purpose! If they live in a neighborhood where it is economical to build 100 unit apartment buildings then a lot with just a single-family home is being wildly underutilized. The higher tax costs will encourage owners to redevelop those properties into apartments or other higher value uses to make efficient use of that land. This is the entire point of Land Value Tax! It makes it in the interest of land owners to upgrade and improve their property (whereas traditional property taxes have a negative incentive because building a new building will increase your taxes).
This article claims that higher threadcounts (as high as 680) improves the filtering of 2-layer 100% cotton masks. However, it seems that threadcounts this high are primarily a marketing gimmick by sheet makers that don't really make practical sense. Furthermore, because it's marketing gimmick, you can't really go out and buy so-called "680 threadcount cotton fabric" you can get sheets labeled that way but not a bolt of fabric from a craft store. I wan't to know what fabric they actually used to make this theoretical mask, without that this seems pretty specious.
Why do you think high threadcounts are a marketing gimmick in this context? Threadcount is just a measure of the number of threads in a square inch of fabric. The higher the threadcount, the denser (and heavier) the fabric is. Higher threadcounts also mean that a fabric is less breathable as less air can pass through.
Generally, craft stores sell only a handful of different threadcounts of a given type of fabric, usually very low threadcount, but in dozens of different patterns, because customers are buying based on patterns, not fabric density. Also, higher threadcount fabrics are more expensive and thus less in demand, so generally need to be purchased special order. Alternatively, you can buy directly from a clothing/fabric wholesaler (though the wholesaler may ask for a reseller's license first).
Yes, it is. Yarn can be twisted in multiple sizes. High thread count fabrics use yarns that are smaller, so that they have fewer individual stands. That is why they feel smoother.
The Schwarzschild radius for the mass of the observable universe is about 13.7 Billion Light Years while the observable universe is about 93 Billion Light Years across (radius ~46 Billion Light Years). So the universe is not itself a black hole (until you take expansion rates into account)
I think you have that backwards--you have to take expansion into account for the "observable" universe to be that large, since the age of the universe is only 13.7 billion years.
Theoretically Apple could probably outbid Nvidia, but realistically regulators would never let Apple make that purchase so it's irrelevant that they have the cash to do so.
I'm not particularly familiar with US antitrust law specifics...
One big point that came up in the congressional hearing the other day was how Google, when buying DoubleClick, said (under oath to congress) that not only would they not merge data but that they legally couldn't if they wanted to - and then years later did just that.
Is there any way to acquire in such a way that Apple would own ARM but there'd be a complete firewall between them, with ARM having a separate board, CEO, etc. and nothing between them except the technical ownership (and any contracts between the two companies)?
I hope not, as I'm in favour of breaking up huge companies myself... but if legal firms can have a system in place for firewall of information between clients I don't see why a similar legal situation could be feasible for allowing Apple to buy on the condition that they can't have any say over operations, with selling ARM being their only way of influencing them in any way?
Of course, owning a company where you have no control at all isn't great, but in this case it might be worth it if Apple trusts ARM to keep doing well without Apple's help, and if it would prevent someone like NVIDIA from shutting Apple out.
And would there be any antitrust issues if Apple bought a 500 year license to freely (or at a pre-set calculation of pricing) use any and all current and future ARM designs?
