That would be easy enough to do yourself with wikipedia and 10 minutes! But this is more interesting I think:
http://www.bbc.co.uk/news/magazine-18976333 Two models for predicting how a country should do, one based just on population size and wealth (US > China > Japan > everyone else) and the other which includes hosting bias and "winningness" (historical performance, probably largely due to investment in olympic sports) (US > Russia > China > everyone else). Nice to see that we do punch above our weight in GB.
I've taken a really long time to get into the olympics, because there has been so so much wrong with how they've been organised, and as a (former) Londoner I think it's a travesty. However, I'm slowly coming round to actually getting into the sport and cheering on the athletes (I saw a tweet today "it's like supporting the troops but hating the war", which sums up my feelings pretty well). We got a bunch of medals yesterday and we're hopefully inspiring a new generation of athletes.
I was also really excited this morning to watch the women's 100m preliminaries, for two women who are blazing a trail in their countries. Noor Hussain Al-Malki, from Qatar, and Tahmina Kohistani, the only female Afghanistani athlete at the olympics (who has had to endure men coming to her training sessions and booing her) appeared in the heats today but sadly didn't qualify. But still, a great moment for them and for every girl growing up in those countries.
On another pro-women note, special mention has to go to
Nur Suryani Mohd Taibi, the first female Malaysian rifle shooter to ever compete at the olympics, who is
eight months pregnant. Impressive.
