Undoubtedly the late stages of pregnancy and the early stages of Motherhood are challenging, but we are talking about a few months.
The issue here extends beyond the physical difficulties of working while pregnant. Many research fields involve exposure to environments and substances that are potentially dangerous to a fetus. Physics (radiation specifically), chemistry (almost any lab-based activity), and some biology research (with pathogens) all have the potential to cause harm to an unborn child. Restrictions on pregnant women in research labs are commonplace and prudent.
MOD PARENT UP. I wish I had points. I used to be a rabid fan of DD-WRT, and I still believe it is the best firmware out there for the WRT series routers. However, the project leader (Brainslayer) has recently started to close source certain parts of the project, and it seems he is working to make it unusable in open-source form (i.e. requires proprietary code to function at all). Basically, he's pulling a Sveasoft move here and screwing a great number of the people who donated time and money to make the system work in the first place.
The first thing to do is get rid of money. Money is an abstraction of power. ... You want food, join a co-operative, and contribute labour.
Then you control your power.
I have a better idea: Collect a bunch of money. You can only contribute labor in the amount that you are actually able to perform yourself. That's not much "power". You can contribute money to whatever extent you can collect it from others. If you're good at collecting it, that may be a whole lot. Then you wield real power. This is starting to sound a lot like capitalism.
Maybe the real route to maximizing one's self interest is not through a commune? Maybe it's through business? Maybe it's hard to achieve this because so many other people already recognize this fact and are also struggling to reach the top? Maybe this is why money as a medium for power exchange develops spontaneously in all organized societies? You can't get rid of money any more than you can get rid of power itself.
Have you paid attention to every news story buried in the middle of the paper? Have you looked up your neighborhood on the online crime maps? You will likely be surprised. These incidents don't get too much press unless the victims are unarmed and multiple murders result. A more typical result is a justified shooting of the intruder, or a single murder of the home occupant -- neither of which make great news in this town anymore. Even if you live in one of the best parts of Phoenix, chances are at least one violent crime has been committed within 1/4 mile of your house in the last year. Check the maps. Carry.

With a vocabulary like that you should consider an English major. Not if he "gleams" his knowledge instead of gleaning it. Your average English major not only knows that one, they can explain the etymology of it.
There once was a man named Fisk
whose thrust of the sword was so brisk
that with the speed of the action
the Lorentz-Fitzgerald Contraction
reduced his rapier to a disk!
Also, we're talking about electrical fuses here. An electrical fuse is a bit of wire or something similar that gets hot and melts when you put too much current through it.
Wrong definition of "fuse". These are the kind commonly spelled "fuze" - an initiating device for an explosive. In the case of a nuclear weapon, the fuze assembly is actually a very complex electronic timing and initiation module that has to synchronize the detonation of dozens or hundreds of individual explosive lenses to within nanoseconds. It's one of the major challenges of building a nuclear bomb - and having one to examine would be very helpful in copying the design.
It appears that the size comparisons for this device do not include the dimensions of the high voltage power supply needed to operate it. It's possible that the efficiency numbers don't include the power supply conversion efficiency either. Since small, efficient high voltage power supplies tend to be highly nontrivial and somewhat expensive to build, that is a significant hurdle to adoption. Consider the size and power draw of the inverter needed to power the backlight in a laptop, and now consider that the voltage required by this fan is about 10 times higher. Efficiency of power supplies drops with increasing voltage ratios, too. I would say this is a significant problem for commercialization of this idea.
I don't quite follow -- v is relative, but dv/dt isn't? That is correct. Steady state velocity is not an attribute that can be measured or even detects within an isolated reference frame. In fact, the concept of velocity is inherently relative and has no meaning within an isolated frame. Acceleration, on the other hand, can be measured within an isolated frame and has meaning even in the absence of any outside reference. Think about it.
I'm not sure I understand.
A DC motor works through the simple mechanism of two electromagnets attracting and repelling a magnet. This causes the magnet to spin. After a half-turn the flow of electricity inverts causing it to go back the other way. Momentum causes it to go up the other side.
However, it's the MAGNET that moves. If one supplies an outside magnet the internal magnet should try to align with it, slowing it down when it's moving away but speeding it up when it's coming towards.
So unless he's alternating the filed some how (which wasn't in the article) this doesn't make sense. You just described a brushless motor (which is really an AC device), not a DC motor. DC motors have fixed magnets (permanent or electromagnetic), and the rotating part consists of coils. The rotating action is responsible for switching the polarity of the DC power applied to the rotating coils, so it happens automatically (through the commutator). In the system you described, there has to be an external device that senses the shaft position and switches polarity to the fixed coils at the correct times, and that is a brushless motor controller. Effectively, the waveform applied to a brushless motor is a customized AC signal that always matches the frequency of the spinning armature.
First and foremost, the claims of this patent are not innovative or novel. They are merely obvious incremental advances in product complexity. The reason these people were able to list them all in a patent application years before the technology hit the market is simply because there were significant technical barriers preventing manufacturers from making a device with these features at the time. Without the basic technology to actually build the device, it's not possible to adequately describe the implementation for patent purposes. That brings us to the second major issue: Failure to reduce the idea to practice. The claims are stated, but at the time the patent application was filed there were significant technical limitations that prevented such a device from actually being built by anyone - and the application did not provide solutions to those problems. Moreover, the company did not undertake any ongoing research to find a solution to those problems (they just waited 10 years for others to do so). Consequently the application fails to provide enough information for one "skilled in the art" to reproduce the invention. In other words, it's a "flying car patent" - an idea is described that is not technically feasible and no practical implementation is detailed. I doubt the legal eagles will have too much of a problem shooting this one down. I think the interesting part is that it was ever granted in the first place. This is a fairly clear indication that the USPTO is relying on subsequent litigation as part of the review process.
The inverse square law only applies to an isotropic source - a light that's being emitted in every direction (like a candle). This is why lasers stay bright at a distance.
This is not correct. The inverse square law applies to all sources of photons (from radio waves all the way up to X-rays, coherent or incoherent). Lasers included. The inverse-square relationship is only measurable, of course, for measurement windows that lie completely inside the field of radiation. In other words, to measure the inverse square relation in a laser beam, you must sample an area smaller than the entire beam. This just makes sense. Stated another way (which is more fundamentally correct), the INTENSITY (watts per unit square area) of incident photons at a given distance from a source varies with the inverse of the square of the distance from the source. This relation eliminates the (potentially confusing) measurement of incident power within a given sample window in favor of intensity measurement.
Aren't most (all?) air conditioning systems ducted to the outside world?
Interestingly not. All modern HVAC systems have some outside air flow, which is required by building codes to keep the indoor air "fresh", but only a small fraction of the air is actually exchanged. For the most part, these systems are mostly closed. In some special applications like data centers, operating rooms, and cleanrooms, the system may actually be completely closed during normal operation.
Keep in mind that this legal wrangling does not apply to organizations that are actually using the spectrum right now. Those entities have the choice of either keeping it or selling it. The problem is that many entities had licenses they didn't use (and didn't renew). Those entities now want to reinstate their old licenses ASAP so they can hold the spectrum hostage from Sprint. Sprint wants these reinstatements blocked so they can have an equal shot at the spectrum.
Most of them. If not plutonium, then a different radioisotope like 90Sr. Radioisotope Thermal Generators (RTG's) are a very common method of providing power for electronics in satellites.
The Magnusson-Moss Warranty Act is a US federal consumer protection law setting requirements for consumer product warranties. One key provision of the act is that a warranty cannot be voided by the use of "unapproved" or "aftermarket" parts, or by modification, unless it can be proven that the damage or failure was caused by that action. The legal burden of proof is on the manufacturer to demonstrate that the customer's actions caused the problem. The intent of this law was to prevent manufacturers from locking customers into using only their own consumables and replacement parts -- a practice that was popular at the time, with products ranging from vacuum cleaners (generic-brand bags void warranty) to cars (OEM replacements parts only, or the whole warranty is void). Many companies will still try to dishonor a warranty if a product has been modified, but this is clearly illegal and case law has upheld the consumer's right to modify products and use "unapproved" accessories and replacements time after time. Long story short -- in the US, you shove the laptop where the sun don't shine and threaten to sue (the American Way). In the UK? I don't know.
Perhaps rather than hoping the community can outpace their support division, Intel should strive to improve their support division so they can always provide timely assistance to their customers?

Quite true - present battery technology is pitiful for bulk energy storage. Compared to any combustion fuel, batteries are at least an order of magnitude worse in terms of watts per kilo or watts per unit volume. The Tesla used a giant array of lithium polymer batteries, which is the best we can do right now. Consider this: An electric car like the Tesla has a battery pack several times larger and heavier than a normal car's full gas tank. The drive system and the vehicle as a whole are much more thermodynamically efficient (miles per watt of input). Yet, the vehicle's range is at most a third of a normal car's. Until electrical energy storage makes at least an order of magnitude improvement in density, electric vehicles will remain highly inconvenient compared to combustion engines.
