What if I don’t accept the law of the excluded middlesetto?

It’s not exactly ½. It’s a little above. The explanation is highly counterintuitive (at least it was to me).

The hypothesis is, unfortunately, false. The easiest counterexample is to remove a2 and b1. This very obviously cannot be tiled (a1 is isolated).

If I remove a8 (upper right) and say… e1 (fifth right in bottom row), I can tile that. In fact, if I remove two squares from anywhere (even the interior) completely at random, the odds I can tile the leftover is pretty much ½. Proving that is quite a bit more difficult.

That’s not entirely true: for example, say you remove the upper left and upper right corners. There are still two odd rows (columns). But you can tile that one. By way of learning, try and figure out what’s different between those two cases.

If someone sat on me in my chair I’d do that head-twisting neck-break thing from the movies.

He doesn’t. I just meant “voters’ solution”. That is, if they have a problem with it, they should consider the alternative. It’s a zero sum game.

The solution to an 80 year old progressive is not a 77 year old fascist.

The people of America did decide he couldn’t run… when they ratified the 14th Amendment.

The red states are extremely anti-protective measures and would rather you die of the consequences than do anything about it

I wish it were bamboo rather than onions so “shoot” was a pun

He’s been going through some things. This was him a few years ago

He looks like that relative the Munsters don’t invite over for holidays.
