Or you could have high expectations, and do your best to help the students meet them. Those who don't would receive a lower grade, with average students receiving an intermediate grade. These grades could then help future colleges and employers judge the students' ability and drive.

Agreed. The vast majority of economics is ideology and/or theory-induced blindness. Of the fairly small number of people who predicted the GFC (I'm not including the large number of finance people who knew mortgage's were doomed, because they didn't understand the larger consequences), only one that I'm aware of was actually an economist: Steve Keen. Not coincidentally, he is also recognized as being one of the major proponents of economic education and policy reform.

That hasn't been true for a long time.

I think they meant "limits to Moore's law". Remember that Moore's law is not a law at all, it's just an observation. Furthermore, the observed doubling time has been steadily increasing for a number of years. Note that Intel missed their last targeted doubling.

The driving factor behind Moore's law has always been economics. Once scaling becomes too expensive, it won't happen (at least not at an exponential rate). We're getting close to that point. 3D transistors have delayed the end of Moore's law for NAND flash, but it's not clear if the same can be done for logic. Unlike NAND flash, the performance of logic circuits is usually limited by heat dissipation. If you go 3D, you might be able to pack in more transistors per unit area, but you can't operate all of those transistors at the same time or they will burn up.

The channel lengths were 60 nm. This is massive compared to the latest generation of CMOS (~14 nm).

The confusion seems to come down to the fact that the SWCNT diameter is ~1 nm. However, 14 nm CMOS already uses FinFET's with channel widths of ~8 nm which is ~60 atoms.

Regardless, the science article is actually about improved contact resistance, which is one of the major challenges associated with continued scaling of CMOS. However, they have only been able to show this improvement for p-channel devices, and they state clearly that n-channel devices present a much larger problem. If you want to replace CMOS, you need both n-channel and p-channel devices (not to mention fabrication yield needs to be as close to perfect as Si CMOS is). Thus my subject line (see above).

Newton was an avid Alchemist and spent more time searching for the elixir of life than developing calculus and his theories of motion and optics.

You could print out the secret keys as Q codes and then secure delete the files from your HDD. At that point it's essentially as safe as cash (ignoring exchange volatility). Unlike cash, you can even make backup copies.

The SI unit for pressure is the Pascal, which is equal to one Newton per square meter, i.e. force per unit area. A paper weight does not apply pressure on a table without some acceleration applied, e.g. gravity. Please check your facts before correcting others.

To be fair, government employees don't really fall under Capitalism (the concept). Nonetheless, when it comes to invading our privacy, private corporations are at least as effective as the government. The difference is that the former are pursuing profit, while the latter are pursuing power and control.

This is certainly the case in Austin. I don't know the numbers, but way way way more people use Uber and Lyft than ever used taxis. And the streets are safer for it (less drunk driving).

Unless you have a causal mechanism and argument, generated through the scientific method...

"...over a protracted period of good times, capitalist economies tend to move from a financial structure dominated by hedge finance units to a structure in which there is large weight to units engaged in speculative and Ponzi finance. Furthermore, if an economy with a sizeable body of speculative financial units is in an inflationary state, and the authorities attempt to exorcise inflation by monetary constraint, then speculative units will become Ponzi units and the net worth of previously Ponzi units will quickly evaporate. Consequently, units with cash flow shortfalls will be forced to try to make position by selling out position. This is likely to lead to a collapse of asset values.â

The waves probably did travel faster than light. This is a well known property of waveguides below cutoff. Even the group velocity can travel faster than light if the attenuation is large enough. However, energy transfer is limited to the speed of light.

The whole "nothing can travel faster than light" claim is an over generalization. A lot of things travel faster than light, just not matter, energy, or information.

The patent points to PCM. Maybe they're applying the same X-Point structure to a different material system, though. I'm guessing, however, that they're just saying it's not PCM in an attempt to dodge other patents.
