How do empires work?

...sustained an increasing gap between European and non-European naval powers, a difference captured by Figure 2, which show the Nemesis in action. European naval powers, meanwhile, were finely balanced among themselves until the Napoleonic Wars of 1795–1815, from which Britain emerged master of the seas.

Studying mammals: Return to the water

...sustain life, so aquatic mammals must come to the surface at intervals to breathe; and all of them - pinnipeds, sirenians and cetaceans - drown if they are prevented from doing so for prolonged periods. Lungs form 7% of the body mass of a human being, but no more than 3% of the body mass of most cetaceans - so lung size alone cannot account for their diving abilities....

However, these evolved modes...

A central tenet of academic art theory, which Reynolds did much to promote, was that artists should demonstrate a capacity for ‘invention’ and ‘design’ by depicting elevated subjects derived from biblical, historical and mythological sources – capacities that were...

10 years of The Bottom Line

...sustainably without extra, without sorting out the debts, and we plainly can’t sort out the debts if there’s no income for people to earn to pay down, to save and pay off their debts. So rather than seeing it as a choice of theories or a choice of risks, I see it as a catch 22. It’s a very uncomfortable place to be that we need both these things to operate. Both...
