On this day in 1870, Alfred Ely Beach unveiled his pneumatic powered subway line to the public. It was an immediate novelty attraction and was popular for the first year or so, until a stock market crash crushed Beach's dreams for good.

In the 1920s, the prevailing quantum theory modeled the atom as having electrons in fixed quantized orbits around a nucleus, and, though this model worked well for hydrogen, there were problems with larger atoms and molecules. Werner Heisenberg objected to this model and he started work on trying to come up with a quantum mechanics formulation that relied on properties that could be observed....

In work that could help scientists better understand the formation of freezing rain, researchers explained in detail why supercooled drops of water that are triggered to rapidly freeze will then spontaneously shatter.

On this day in 1987, Ian Shelton was taking a routine telescopic photo of a small galaxy 167,000 light-years from Earth called the Large Magellanic Cloud. Upon developing the photographic plate, he realized an aging massive star that had blown apart in a supernova explosion.

Normally the spins of electrons point in random directions, but future electronic devices may depend on aligning many electron spins (creating "spin polarization") in a material. Researchers have now developed a technique to probe the spin polarization below the surface of members of an important family of materials that have spin polarized electrons in the absence of an external magnetic...

During Amadeo Avogadro's lifetime, there was much uncertainty in not only the government, but physics as well. A hot topic of debate was figuring out if oxygen was an atom or a diatomic molecule. Avogadro resolved this question and his discovery of the fundamental numerical property of gases underlies our understanding of the molecular world.

A type Ia supernova occurs when a white dwarf star's companion transfers enough material to produce a runaway nuclear fusion reaction. But astrophysicists have multiple models for the details of that process. New computer simulations suggest that the burst of neutrinos from one of these supernovae in our neighborhood will allow researchers to distinguish among the models.

Physicists have been long fascinated by materials such as glasses and pastes that are very slow to readjust to new conditions. Often their slow reactions depend on some event in the past, so they are said to have a memory. These materials have been analyzed at the molecular scale, but now researchers have shown that Mylar—candy wrapper material—has a days-long memory in its macroscopic...

James Chadwick was one of the many scientists who witnessed the Trinity test on July 16, 1945. Even though many scientists were able to contribute to this achievement, it was his discovery of the neutron in 1932 that made it possible in the first place.

Physicists at ESPCI Paris learned about this beautiful effect from a colleague who had been showing it to children at science festivals. After performing a series of experiments, the physicists say the phenomenon results from the combined effects of evaporation, surface tension, and fluid flow. One key element of the theory is the so-called Marangoni effect, where fluid flows from a region of...

Why would theorists propose more new fundamental particles? This new theory, if correct, would solve five of the major problems in all of physics, including the sources of dark matter and cosmic inflation and the cause of the imbalance of matter and anti-matter in the Universe—huge breakthroughs if the theory pans out. The authors say the theory can be tested with future observations of the...
