Sikorsky flew its prototype counterrotating helicopter yesterday (press release). Typical helicopters, however expensive, are limited to about 165 knots of cruise speed. When the helicopter is moving faster than that, the “retreating blade” is not getting enough airflow, i.e., the blade is going backward about as fast as the helicopter is going forward. This results in a loss of lift on half of the disk. With two rotor systems rotating in opposite directions you still ...

David Campbell is bringing Florida’s mandate to teach evolution to many students raised to take the biblical creation story as fact.

Roosh said:
Fascinating.America's obsession with mislabelling evolution as a disputable scientific theory (all science is theories supported by evidence, and anything can be disputed in the fact of contrary evidence, this is *basic* *science*) and then demonizing it by claiming its 'just a theory'. This is the interesting / fascinating part.Getting rid of evolution and teaching biblical stories instead is the really scary part.The part I really like is the bit about how the teacher - Mr. Campbell - makes an effort to explain that science and faith are not at odds with each other. If something can neither be proven or disproven, science doesn't care.

slacy said:
This is the exact analog of what happens on a single machine with dual CPUs and no shared cache. When CPU A writes to RAM, CPU B is snooping on the address bus and comparing the addresses of its cached items. If there's a match, then it invalidates its local cache. Most single-die, dual-core CPUs these days have a single shared instructio/data cache to avoid having to do this, but when you have multiple dies, there's no way to avoid this that I know of.

Galbraith sets himself the task, not only of exposing the discredited economic orthodoxies of our generation, but also documenting the economy as it really exists, and setting an agenda for the future. It is a book that desperately need to be listened to. And, even better than all that, it's a fun read. Go out ...

The US is not a free market. Of GDP, 17% is health care (where experts, not consumers decide how to spend), 16% is housing (subsidized by quasi-public mortgage firms and tax deductions), 15% is federal welfare, 14% is local welfare, 4.5% is military spending, 3% is higher education (paid for mostly by government or conspicuous philanthropy1 and consumed for status and not value). Together, 70% of US GDP is planned; it's just that our facade of a free market makes us less efficient at planning than other countries (especially in health care).
