Wikipedia articles of interest

I think I’ll drop the word random from the post titles of these posts in the future. It’s only the subjects that are somewhat random, not the articles – I go through a non-trivial amount of effort to pick out some of the most interesting of the articles I read. Anyway…

1) Orbital mechanics.

2) Pelagic fish.

…wait, reading an article about fish? Is that guy serious? How boring! …think again:

(more here. Also, here’s an article providing some more context).

3) Roman–Persian Wars. A featured article. There were a lot of wars going on but I doubt this region is all that special in that regard – the difference is that in this region of the world there were often someone around who’d write down something after people had stopped killing each other. If you’re somewhat unfamiliar with this argument, go here and extrapolate. Here’s btw. a nice illustration from the article, click to enlarge:

Case in point: The ‘West African Peoples’ didn’t write much, if anything, down. That’s why they’re called ‘West African Peoples’.

4) Brown rat. It’s a pretty successful species:

‘The only brown rat-free zones in the world are the Arctic, the Antarctic, some especially isolated islands, the province of Alberta in Canada,[45] and certain conservation areas in New Zealand[46][47]’

5) Lake Baikal. Never heard of it? You should have. It is ‘the most voluminous freshwater lake in the world with an average depth of 744.4 m (2,442 ft) and contains a total of roughly 20% of the world’s surface fresh water.’ It’s more than 25 million years old.

Here’s one image of (part of) the lake:

And here’s another:

6) Candela. The SI base unit of luminous intensity. Lots of related links in the article.
