The creation of modern quantum mechanics was a messy business in which many of the participants did not grasp the significance of their own discoveries. The wave nature of electrons is revealed in ...

Jungsang Kim is a professor of Electrical and Computer Engineering, Physics, and Computer Science at Duke University in North Carolina. He leads the Multifunctional Integrated Systems Technology group ...

Interest in developing batteries based on sodium has recently spiked because of concerns over the sustainability of lithium, which is found in most laptop and electric vehicle batteries. In the 1870 ...

New experiments suggest that superconductivity in twisted bilayer graphene depends on an unconventional electron-pairing mechanism. Figure 1: Two twisted bilayer graphene (TBG) layers stacked one on ...

Collider experiments have set new direct limits on the existence of hypothetical heavy neutrinos, helping to constrain how ordinary neutrinos get their mass. Figure 1: In the seesaw mechanism, a ...

Which direction would an S-shaped lawn sprinkler rotate if it were submerged and the flow were reversed? Experiments now provide a definitive answer. A fluorescent dye traces out the flow pattern as ...

Figure 1: Laser cooling of atoms progressed from elements with one valence electron (top left) to two valence electrons (bottom left). Now with molecules, researchers are going from molecules with one ...

Figure 1: The shattering of glass is an archetypal fragmentation process. × When a solid object shatters or a liquid drop disintegrates, predicting the outcome seems at first hopelessly difficult. In ...

For a wide range of complex fluids, the transition from solid-like at rest to liquid-like when pushed can be predicted from properties of the at-rest state. Slow flow. Slow flow. Yield stress fluids ...

Figure 1: (Left) Cross section of the spherical capsule used at NIF. The capsule is encased in a cavity (hohlraum) and ablated by x rays during a laser pulse. Its core consists of a gas of deuterium ...

Macroscopic quantum properties of helium-4, one of the simplest and oldest elements in the universe, continue to puzzle and amaze scientists. Supertransport in solid helium-4 is the most elusive and ...

Measurements of the decay of the Higgs boson into muon–antimuon pairs provide evidence for the mechanism by which quarks and leptons acquire their mass. Figure 1: Display of a proton–proton collision ...
