I find it interesting that it hurts films and books. I wonder what the difference is there?

I suspect part of it is a large number of people read a book once, or watch a film once and rarely doso again. They want access to the product until they've finished it then they're done.

Whereas games you can replay, you can do in a different way, you can come back to. Getting a copy of a game lets you try it, and sometimes you like it enough to buy it to play online, etc.

Me, I reread books a lot, and have ended up buying books I'd borrowed from the library, etc. Same with films. But apparently most people don't do this, so for them a copy is a lost sale, for me a copy is a potential advert.

Wow. I had not imagined electric planes would be possible!

What's Moore's Law for battery storage?

> the Korean term for 1/3, sam bun ui il, translates as “of three parts, one” – compared to the English “one third”.

I remember as a kid doing fractions, maybe aged only about 8 or 9 or something, and always saying to myself as I read them or wrote them down, '1 of the 3 thirds'.

I did alright with fractions. Maybe that trick helped more than I realized.

I feel like, if there's even a whisper of children (or please not, teachers) not knowing that 7/8 is "nearly 1", they need those little rods, one colour for "one", and other colours for other common values and fractions, so you can SEE what 1/3, 1/4, 3/4 etc are, and that 3/4+1/3 is "a bit more than one", and then when someone explains how to do the calculation, you get "ooooh! i see" not "ok, I will confirm and learn these meaningless manipulations by rote".

Fascinating to see about electric planes. I hope it works soon!

For some reason I always like it when the tags make a perfectly plausible title for the article.

Also when using spreadsheets, doing tax computations or just using a calculator, it really helps to have an idea of the sort of number that you are expecting to end up with. Not to mention doing the weekly shop.
