How efficiently could quantum engines operate?
Fermilab’s TeVatron just released the best mass measurement of the W-boson, ever. Here’s what doesn’t add up.
The relationship between these two ways of thinking about the world deserves deeper exploration.
The James Webb Space Telescope could help scientists learn about the cosmic dark ages and how they ended.
Astronomers used supercomputers and an international network of antennas to create the stunning map.
We cannot deduce laws about a higher level of complexity by starting with a lower level of complexity. Here, reductionism meets a brick wall.
The rhetorical fallout is greater than the radioactive fallout.
More than any other of Einstein’s equations, E = mc² is the most recognizable to people. But what does it all mean?
“When molecules misbehave, it can lead to great insight.”
Life is possible because of asymmetries, such as an imbalance between matter and antimatter and the “handedness” (chirality) of molecules.
If the electromagnetic and weak forces unify to make the electroweak force, maybe, at even higher energies, something even greater happens?
The ten greatest ideas in science form the bedrock of modern biology, chemistry, and physics. Everyone should be familiar with them.
The Universe has asymmetries, but that’s a good thing. Imperfections are essential for the existence of stars and even life itself.
Why power generated through nuclear fusion will be the future, but not the present, solution to humanity’s energy needs.
The laws of physics obey certain symmetries and defy others. It’s theoretically tempting to add new ones, but reality doesn’t agree.
Some U.S. intelligence operatives have suggested foreign adversaries may be using “directed-energy” weapons against Americans.
At a fundamental level, nobody knows whether gravity is truly quantum in nature. A novel experiment strongly hints that it is.
New technology is helping physicists move forward in the search for the Theory of Everything.
In movies and TV shows, aliens look like pointy-eared humans. Is this realistic? If evolution is predictable, then it very well might be.
Particle physics needs a new collider to supersede the Large Hadron Collider. Muons, not electrons or protons, might hold the key.
Even without the greatest individual scientist of all, every one of his great scientific advances would still have occurred. Eventually.
No matter how hard we try, we will never reach a final theory that unifies scientific knowledge. The very nature of science doesn’t allow it.
From high school through the professional ranks, physicists never tire of Newton’s second law.
No matter how controversial or politicized our world becomes, science remains humanity’s best tool for figuring out how things work.
Quantum mechanics + consciousness: There is nothing better than mixing two great mysteries to produce an even bigger one.
Many still cling to the idea that we live in a deterministic Universe, despite the nature of quantum physics. Now, the “least spooky” interpretation no longer works.
There are over 100 known elements in the periodic table. These 8 ways of making them account for every one.
Quantum physics isn’t quite magic, but it requires an entirely novel set of rules to make sense of the quantum universe.
Einstein hated “spooky action at a distance,” but much to his chagrin, quantum mechanics remains as spooky as ever.
Chemical energy, where electrons transition in atoms, powers the reactions we see. But two other types hold more promise than all the rest.
