Just a heads up to those who haven't published in peer review journals: hyping the potential commercial applications of your research, no matter how mundane the discovery, is required. Worse yet, the published work concerns simulations. Simulations are cool, and have great value, but they don't constitute discovery. Confirmation of a theoretical prediction by experimentalists constitutes a discovery. Even if the effe…

> I long for the day when people can do good science just for the sake of good science, and not have to spin every single paper as being the start of some new revolution that never seems to come. I absolutely agree - but I think that's only going to happen when people's livlihoods are not dependent on the immediate value of their research.

J. J. Thompson (who discovered the electron) said this about 100 years ago:

If you pay a man a salary for doing research, he and you will want to have something to point to at the end of the year to show that the money has not been wasted.

In promising work of the highest class, however, results do no come in this regular fashion, in fact years may pass without any tangible result being obtained, and the position of the paid worker would be very embarrassing and he would naturally take to work on a lower, or at any rate a different plane where he could be sure of getting year by year tangible results which would justify his salary.

The position is this: You want one kind of research, but, if you pay a man to do it, it will drive him to research of a different kind. The only thing to do is to pay him for doing something else and give him enough leisure to do research for the love of it.

Does electricity at this level -- electrons moving in a corkscrew motion down a wire -- generate an electromagnetic field? If so, how does this field differ from electron motion in a normal conductor?

It is creating an electric field for every observer not in a reference frame at rest with respect to the electron.

I thought this was a remarkably bizarre sentence: > "Unlike the wires we know from everyday life, where electric current runs directly through the wire, the current runs in a circular fashion as it proceeds through these molecules. This behaviour is due to a quantum mechanical effect known as electrohelicity, which in this case causes electrons in molecules to move in a helical fashion, spiralling around the molecule…

It can be useful to introduce a canonical term for a phenomenon, even if there is limited immediate explanatory value.

In this case it was just poorly done; they explained that it was caused by X, then redundantly restated that X caused it but in a format that looks like X was being defined
