The /. title of this article is wrong, stupid and misleading.

The title of TFA is "Dynamical mass generation via space compactification in graphene", which is mostly incomprehensible.

The abstract sez "Fermions in a graphene sheet behave like massless particles. We show that by folding the sheet into a tube they acquire non-zero effective mass as they move along the tube axis. That is, changing the space topology of graphene from 2D to 1D (space compactification) changes the 2D massless problem into an effective massive 1D problem."

A plain english annotated translation is "Electrons in a graphene sheet behave like massless particles. We show that by folding the sheet into a tube they behave like massive particles as they move along the tube axis. That is, changing the shape of graphene from 2D to 1D changes the 2D massless problem into an effective 1D massive problem, which may be easier to solve or model or understand in certain respects.

Note electrons have the same real mass in both cases. Mass is not being created or destroyed.

This sounds like the first step in human batteries, ala The Matrix.

...means the net will lose speed every time it captures some junk. The author needs to take high school physics again.

Tacking on a sailboat works because the wind is blowing on the sail, adding energy to the whole craft.

Scooping stuff in a net is just an inelastic collision. The momentum gain of the junk will equal the momentum loss of the net. The net's orbit will decay as it captures more and more junk.

The Insert key is essential for restoring insert mode after you have accidentally hit Insert by mistake.

It has no other use.

The steam engine was built without understanding thermodynamics. In fact, thermodynamics arose out of a desire to understand the steam engine.

Weird Al was great with "Eat it!"

Actually, it's the Earth and the Sun. It's on the Earth-Sun line, behind the earth (from the sun's point of view), and orbits the sun once a year. They put it here because it's easier to shield the satellite from both the Sun and Earth.

The L2 point for the Earth-Moon system is on the Earth-Moon line, behind the moon, and orbits the earth once evry 29.5 days.

I recognize those two clusters, but there is a another big cluster in my own social network: People who only check their e-mail once a day (or less).

I myself cannot comprehend such behavior.

This mistake proves the premise of the article.

Could it be worse than melting a 40-ton magnet, which actually happened?
