The core of a single-mode fiber is between 1-10um, add a cladding to that and you have a very macroscopic entity. I'm not sure if a material made of carbon-nanotubes can be precisely grown over a large dimension to accommodate this? Fibers are sensitive to bending and having them swing around in...
Why not? There is a huge body of work demonstrating this. I believe you are referring to the "no-cloning" law, which says that a quantum state cannot be cloned. It can be mapped/copied but not cloned.
The fine structure constant is not merely a combination of various fundamental constants in a certain way. It has fundamental significance and has been experimentally measured many many times.

I don't know anything about string theory, but AFAIK there is not a single shred of definitive experimental evidence that confirms it.
Regarding the original topic, we accept that the speed of light is a constant (experimentally proven) in vacuum and build our theories around it.
PS# One...
Nobody knows.
Nobody knows why the fine structure constant turns out to be approximately 1/137. It just is. No known theory seems to explain it without running into circular arguments.
A coherent source has nothing to do with how well collimated it is. Also, the source being single frequency etc etc does not guarantee coherence. The correct way to determine if a source is coherent or not is by photon counting statistics. If the statistics/counting reflect a Poissonian...
You will be in trouble if it was a used unit. However, you may be able to get away with using it if you fan mod it (for 2 x better air-flow).

I'd ditch that Smartpower in a hurry. Low rpm fan+Fuhjjyu crapacitors = Boom! In that wattage range, I'd look at the Corsair VX450 or maybe the Eathwatts (if you prefer Antec).
Same here mate (happy P5K owner). I'd be pretty upset about this situation as well. After this article, Gigabyte would have to take some concrete measures or their reputation would be seriously damaged. Things like this spread like wildfire through the internets.
The older Antec TP's were also over specced by a good 100W. I recapped one and upon obtaining the ATE results was shocked because the damn thing fell apart. Huge pulsations > 400mV on the 12V and VReg was all over the place. Clearly, the SP400 was not a 400W unit, it was more like a 300W unit...
Having one voltage makes sense, but remember that the trend with CPU's is that VCore is decreasing while the current per phase is increasing. Computer SMPS designs have to follow this trend as if the voltage is high, then the MB has to do a lot more work in the step down phase of the CPU VRM...
Yeah..software is not too accurate. However, most boards show some droop when overclocked. The magnitude depends on how the Droop control is implemented in the Buck Regulator-PWM feedback loop. There should be a pin labelled "Droop" on your Buck-regulator datasheet. You might have to alter the...
Hi folks,
If you have taken out/replaced/removed your stock cooling apparatus on the motherboard, please take a moment to note down any information you can regarding the PWM-IC's and Voltage regulators near the CPU, being used. It would be great if you can find a data sheet as well.
You...
Guys, it is not so simple. Kill-A-Watt readings are not always accurate, especially if line distortion and phase displacement factors are not taken into account. It is a lot more complicated than you think. A $30 device won't provide the necessary compensatory services. If you don't know what...
Same PSU. Note that these are based on older Etasis designs that are not very efficient. I have not seen any tests of the 850W unit, but given Etasis' track record and the superb voltage regulation of the 750W unit, it is not a stretch to say that the 850W unit would be just as good.
I'd avoid the TP series (completely different from the Quattro series). The 630 W you mention is afflicted by the Fujhhyu syndrome (bad caps). Depending on your budget, there are several good 500W+ PSU out there that will meet your needs.
My analysis: <Apologies for the shameless self-promotion> :(

The article says CWT, but it is NOT a CWT build. I made a mistake by reading off from the WRONG PCB. I had an antec TP sitting right by it and read the marking off of that one instead.
More...
If the TR2 is built by CWT (likely), it is going to be full of the dreaded Fujjhuyu crapacitors.
If it is built by HEC, you are going to have an almost empty secondary side...lol
Either way, it is a lose-lose..
