Tom Hartsfield is a PhD physicist. He lives in Los Alamos, New Mexico.
The Hyperloop is physically possible, but engineering challenges will make its construction very difficult. Also, accidents would be catastrophic.
Searching for truth in unorthodox ways can be a valuable exercise. But Anatoly Fomenko's alternate world history is just plain weird.
The apes taught sign language didn't understand what they were doing. They were merely "aping" their caretakers.
Nanofabricators could quickly synthesize whatever we need, molecule by molecule.
The European Space Agency’s Solar Orbiter recently captured images that could help scientists better under the mysterious physics of our Sun.
To study the origin of the Universe, we could build a constellation of six expensive spacecraft — or we could just use the Moon.
A famous explorer's doomed ship is finally found 107 years after it was lost to the Antarctic deep.
The rhetorical fallout is greater than the radioactive fallout.
Da Vinci dreamed up a helicopter 400 years before they actually existed. Now, engineers have brought his design to life, but with a twist.
A century ago, electric cars were common. The fact that they were almost entirely replaced due to the internal combustion engine is a testament to the glacial pace of battery breakthroughs.
Are hardened wood knives and nails coming to a store near you?
Asymmetric organocatalysis is an environmentally friendly way of accelerating chemical reactions and creating specific types of molecules.
The cause of the recent uptick in radiation is unknown, but speculation about another catastrophe at Chernobyl is hyperbolic.
Engineers borrowed the maple tree's "helicopter" to design tiny, flying microchips, which perform various tasks while in whirling free fall.
In the name of fighting horrific crimes, Apple threatens to open Pandora's box.
The power tower has superior physics but inferior economics.
Let's celebrate the progress, but put the cork back in the champagne bottle.
As important as his Nobel Prize-winning technical accomplishments was his ability to communicate to the public.
Be skeptical of any theory that produces the possibility of time travel, particularly if it relies on wormholes. That’s not a theory based on physical reality, but rather fodder for science fiction writers and television shows.
In our material, measurable world, infinity is never a real, physical quantity; it is only an abstraction.
There is a reserve of extra performance that the body can be tricked into accessing in competition.
Do you believe in free will? Some physicists and neuroscientists believe in the opposite proposition: determinism. The mathematics of quantum mechanics have a say in this argument: Determinism is impossible […]
There is simply no way that a comprehensive human brain simulation will be feasible in the near future.
