The US Department of Energy's Thomas Jefferson National Accelerator Facility, the Massachusetts Institute of Technology, and Sputnik Animation present a new animation of the particles and forces ...

The nucleus is very small compared to the atom as a whole: as electrons are even smaller, most of an atom is empty space the diameter of a nucleus can be 100,000 times less than the diameter of an ...

Studying the structure of the atom on smaller scales and being able to produce particles with higher masses is what drove the development of accelerators with ever-higher energies. In a ...

The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and one electron in the region outside the nucleus. The electron and proton are attracted to each other.

IN a letter to NATURE of November 25 last Dr. Norman Campbell discusses the problem of the possible consistency of the assumptions about the motion and arrangement of electrons in the atom ...

Everyday things that we take for granted, things like cause-and-effect and elementary classical laws do not work in the world inside the atom ... “Quantum Tunnelling animation” by Yuvalr ...

In fact, each gene in cellular DNA contains the code for a unique protein structure. Not only are these ... that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

Everyone at that time imagined the atom as a "plum pudding." That is, it was roughly the same consistency throughout, with negatively-charged electrons scattered about in it like raisins in a pudding.

Glucose is made from carbon, hydrogen, and oxygen atoms. The structure of wood is made of many cellulose molecules stacked together. Plastic and wood can have similar densities because they are made ...
