Particle accelerators are a massive invention of the twentieth century. within the final 8 many years, they've got developed drastically and feature essentially replaced the way in which we are living, imagine and paintings. Accelerators are the main robust microscopes for viewing the tiniest internal constitution of cells, genes, molecules, atoms and their components resembling protons, neutrons, electrons, neutrinos and quarks.

Example text

It is only within the past few decades that astronomers have been able to study emission and/or absorption lines in the infrared, ultraviolet (at which wavelengths the Lyman lines are to be found), and X-ray regions. Stars generally show a composite spectrum that is derived from a combination of a blackbody curve The New Quantum Mechanics 21 (recall Fig. 11) and wavelength specific absorption lines. The blackbody curve is produced by the high-density, high-temperature interior gas, while the absorption lines are produced through the presence of atoms located within the outer, cooler, less-dense stellar envelope.

Theoretical physics was in crisis, and a revised fundamental theory of atomic structure had to be found. Not only did the new theory have to explain what the structural components of the proton and neutron were, it also had to explain and classify the panoply of other particles that were being detected. Many physicists were working on the problem, but the first person (although to be fair one should say with the help of many collaborators) to hit upon what is now accepted as the right explanation was Murray Gell-Mann (the California Institute of Technology) in 1956 (Fig.

The first two Lyman absorption lines emanating from the ground state (n = 1 to n = 2 and n = 1 to n = 3) are shown and so, too, is the first Balmer absorption line emanating from the second allowed electron orbit (the n = 2 to n = 3 transition). The n = 3 to n = 1 Lyman emission line is also illustrated 1 The Story of Matter Photon carries away excess energy of electron 1st Balmer line 1st & 2nd Lyman lines Proton Ground state 1st excited state 2nd excited state n=1 n=2 n=3 or down to the n = 2 (second allowed) orbital.
