Both molarity and molality are measures of a chemical solution’s concentration. The primary difference between the two comes down to mass versus volume. Molarity (M) is the amount of a substance in a ...

On weekday mornings in late winter, they start to arrive before dawn. They drive in from Arizona or California, catch a shuttle from Yuma, or park their car in a lot in the Sonoran Desert and cross ...

A pioneering team at the University of Maryland has captured the first-ever images of atomic thermal vibrations, unlocking an unseen world of motion within two-dimensional materials. Their innovative ...

Extremely cold atoms have been connected into a state of quantum “hyperentanglement” for the first time. This demonstrates a new level of control over their quantum properties, which could prove ...

Until now, atoms have never been imaged interacting freely in space, but a new technique known as non-resolved microscopy has changed that. MIT physicists were able to successfully capture images of ...

James is a published author with multiple pop-history and science books to his name. He specializes in history, space, strange science, and anything out of the ordinary.View full profile James is a ...

Scientists have demonstrated that atoms can exhibit wave-like behavior, challenging long-held assumptions that experiments of this nature were impossible and opening new doors in quantum physics. The ...

From nearly indestructible metals, like tungsten, to delicate clouds in the sky, atoms make up everything around us. But do these atoms ever touch each other? As with most topics in atomic physics, ...

I love thinking about things I can’t see with just my eyes. Like the atoms that make up everything. I asked my friend Fred Gittes how to figure out the number of atoms in a leaf. He’s a physicist at ...

Physicists directly observed ultracold atoms in an 'edge state,' flowing along a boundary without resistance. The research could help physicists manipulate electrons to flow without friction in ...

Molar mass is the mass of one mole of a given substance, typically expressed in grams per mole (g/mol). It is a fundamental concept in chemistry that helps relate the mass of a substance to the amount ...

What is Atom and Molecule? Atoms and molecules are an important part of science and the building blocks of matter. Understanding them is the foundation for understanding all branches of science.
