The scattering of high-energy electrons from nuclear and nucleon targets provides a microscope for examining the structure of these tiny objects. The best evidence we have on what nuclei and nucleons ...

In 1959 Richard Feynman called for researchers to improve the resolution of the electron microscope, and they have — but resolution is only part of the story. You have full access to this ...

A decade after the discovery of the “amplituhedron,” physicists have excavated more of the timeless geometry underlying the ...

On a similar note, many dark-matter candidates are predicted to produce more cosmic-ray antiprotons than are observed if the annihilation rate is normalized to the electron and positron signals ...

The later chapters tackle interesting applications ranging from one-electron and many-electron ... of QM are marked including the hydrogen atom, Feynman path integrals, light-matter interaction and ...

The varying degrees of electron scattering or absorption by different components of the specimen result in variations in contrast in the image, allowing for the observation of structures down to the ...

and we give the equation of motion of a relativistic electron in a classical electromagnetic field. Finally, we explore some topics in quantum field theory, such as the Lagrangian formalism, ...

Stem and leaf diagrams make it easier to read lists of number Stem and leaf diagrams are formed by splitting the number into two parts, the ‘stem’ and the ‘leaf. For example: In the number ...

Richard Feynman (1918-88) was one of the most remarkable and gifted theoretical physicists of any generation. He was also known as the 'Great Explainer' because of his passion for helping non ...

The elements of a Feynman diagram. Back in the late 1940s ... craft that would use deuterium/helium-3 fuel pellets, with an electron beam using the concept of inertial confinement fusion to ...

We may earn commission if you buy from a link. Why Trust Us? Scientists have set up and observed a single electron bond between two carbon molecules. A traditional “single bond” is actually ...
