In Hilbert Space, All Things Are Quantumly Possible
To explore quantum phenomena, we must leave the familiar world and enter the abstract realm of Hilbert space.
Building a Quantum Computer, One Fragile Qubit at a Time
No one yet knows which technology will power the quantum computers of the future, but the race to create them has already produced some of science’s most intricate machinery.
Theory of Fluids Enters the 21st Century
From the 1800s to the early 2000s, physicists used the same theory to understand the behavior of fluids. Now, using a modern insight, they have redefined fluids from the bottom up.
Neutrinos From Deep Inside Earth Provide a New Picture of the Mantle
A global constellation of neutrino detectors is creating a never-before-seen view of the radioactive elements that power Earth’s tectonic heat engine.
Physicists Solve a Big Quantum Mystery. Now, Old Results Don’t Add Up.
New calculations seem to have put a 25-year-old particle physics puzzle to rest. But they’ve also created a clash with other experimental results.
How Fast Is the Universe Really Expanding?
One of the most contested issues in astrophysics is our understanding of the Universe’s expansion. Adam Riess discusses why there is disagreement and what might resolve it.
Thermodynamic Computers Go With the (Energy) Flow
Today’s computers need safeguards against random energy fluctuations. Thermodynamic computers would put those fluctuations to use.
We Know Simple Fluids Can Flow. Turns Out, Some Can Fracture.
Researchers thought that what enabled complex fluids to break apart was their elasticity. But a crack in a nonelastic simple fluid has them questioning that idea.
Astrophysicists Puzzle Over Webb’s New Universe
Faced with observations of early black holes and galaxies that weren’t expected to exist, scientists have come up with a wealth of new theories to explain them. Now they just need to figure out which ones are true.
