"The scientists realised that the cryptochromes could well be involved in the perception of the magnetic field, as they have all the physical and chemical properties needed, notably the absorption of blue and green light and the formation of 'radical pairs' - molecules which respond to magnetic fields."
So blue light must have the right energy level (see quantum physics) to interact with the molecule's electrons and cause the change.
I personally think that the these days (apart from a few extreme cases), the "glass ceiling" is self inflicted by most women.
There seems to be alot more politics/personal emotion involved with female employees. Most of the guys I've met can have problems with a few colleagues and still get their job done without fuss. Getting the job done gets you the promotions.
This is a kinetic effect rather than variation, using a different tool. The bump key knocks the lower section of the pins all at the same time. The top pins all fly off like a newtons cradle, leaving a gap where the barrel can be turned.
As long as you have the right key profile, this works for a huge range of pin/ball locks, even expensive ones.
As far as I am aware, the faster a gate is able to switch, the less heat it should produce. One of the main sources of heat comes from the transition between conducting/non conducting, so speeding up the transition would help.
Due to the design of semiconductor transistors, they have on (conducting - high amps, low volts) and off (non conducting - low amps, high volts) states. These discrete states have very low losses (power = volts x amps).
Unfortunately, during the transistion there are nanoseconds where it is in the partially conducting state. Both the current and voltage are at intermediate values, and the power dissipation rises. The more often they switch, the more often these losses occur, which is why CPU heat is dependant on the operating frequency.
Spintronics may use a fundamentally differnt signalling mechanism which doesnt involve these transition losses.
No matter how good the sensor technology is, you still have humans driving the system.
A funny example is an industrial town I fly to on a regular basis. Most of the people work in the mines, where explosives can be a common part of many poeples jobs. When explosives traces are regularly detected at the airport explosives scan, their first question is "Have you been on a mine site recently?" Obviously 99% of people say yes, and are let through without question.
What is the point? We're running around banning knitting needles and letter openers and it makes no fucking difference.
By having a rigidly mounted flywheel, you might place too much stress on the magnetic bearing and it could make contact with the bearing surface (and thus destroy itself).
I saw one solution was a flwexible battery compartment where the batteries could pivot from an overhead hanger.
Alternately, this can be expressed as: People who die before they get their children raised to self sufficiency represent a bad trait that natural selection theoretically should put some pressure against.
Quite a valid point, but from an evolutionary basis, surviving till you're 25-30 (two quick generations) is far easier than surviving till you're 40-50, which is where obesity and heart disease really get nasty.
Im using one of those at the moment, and whilst it gave temporary relief, the pain just shifted to a differnt part of my forearm.
Overall I found much greater benefit from 1) stretching - particularly my neck where the nerves in the wrist originate. 2) learning to mouse with my left hand, and now I switch back and forth during the day.
I'd been coping quite well until recently where I became slack and forgot to stretch. The same pain is back again in my writs and Im having to ease it back out again.
I've talked to another person who found yoga and swimming worked wonders. I've been trying a few laps but I'm far from dedicated.
Top advice and I agree. I was having RSI like issues (nerve mobility) and the physio provided great support/treatment/advice. Between stretching, massage and swaping hands it's now manageable.
I agree. Im 29 and consider myself to be pretty bright, yet I only discovered that misconception a year ago. Both the education system and mass media repeat "popular" junk science, and it was only by accident that I drilled into a deeper explanation on lift and was suprised with the real science.
This site has a pretty good explanation. My favourite sentence is this:
Students of physics and aerodynamics are taught that airplanes fly as a result of Bernoulli's principle, which says that if air speeds up the pressure is lowered. Thus a wing generates lift because the air goes faster over the top creating a region of low pressure, and thus lift. This explanation usually satisfies the curious and few challenge the conclusions. Some may wonder why the air goes faster over the top of the wing and this is where the popular explanation of lift falls apart.
I also recall somewhere that the atmosphere was thicker at that point, thus was capable of providing greater lift - for the same volume of displaced air, the mass was greater hence a larger reaction force.
In order for condensing vapour to lower the vapour pressure in a manageable way, the unit would need to be sealed. If it's sealed then why cant the initially vapourised lubricant be re-deposited and recycled?
PS - I know you can have local vapour pressure changes without a sealed environmant, but if the drive was ventilated as per normal then you'd get a nasty lubricant loss every time the drive heated and cooled (started and stopped) - the vapour would be pumped out of the vent hole.

Umm, we've known for many, many years that matter can be created and destroyed. e = mc^2 and all that.
The black holes emit energy, thus losing mass. Eventually all the mass is gone and there will be no singularity.

Are a bunch of geeks really that dense? They'll be using a heat exchanger or separate boiler for the steam, not direct from the garbage plamsa.
I'll probably lose karma for this....

You're lucky you didnt die of liver failure.

All this security is going to stop a stinger missile exactly how?
Dont you remember the defensive "bubble" shield? The "bubble" will save us!!!
Or more importantly, do you math in a system where the level of precision (number of significant digits) is far greater than the answers you require.
That depends if the interference is random.
I can think of lots of non-random interference sources - Mains 50Hz, CPU Clock, USB Clock, other data signal on the USB cable, etc.

Massive clotting would be a pretty good sign of "unnatural causes"
Just like a jet fighter.
That's why you build the control algorithm into a $10 10MHz microcontroller - it can compensate faster than humans.
No matter how good the sensor technology is, you still have humans driving the system.

Same here. For me it's normally preceeded by a feeling of butterflies in the stomach/nausea.
Similar here - I remember having a dream and then seeing it come to life.
Most of the time I cant remember fore than a few seconds about what will happen, but occasionally I think I can remember further.
Truly weird, and Im sure it's just a bain malfunction and doesnt require a tinfoil hat explanation.

Umm, I hope you're joking. Search engines and relational storage go hand in hand - where do you think your store and lookup tags, keywords etc?
