Atomic science material history

Occultists, then, increasingly focused on alchemy as a material science validated by the new atomic chemistry and physics, even if it was a science with spiritual implications. Many occult phenomena now began to be explained in terms of radiation and material particles as occultists turned to scientists to validate their belief.6 Never had modem occultism been so much concerned with the nature of matter—that is, the nature of material change. To understand this development in the relationship between occultism and material science, we must first briefly rehearse the history of the broad occult movement beginning half a century earlier. 

Chemical philosophy. .. has for its aim to reveal the general principles of the science. .. [to give its history], to give an explanation of the most general of chemical phenomena, to establish the link between facts and the cause of the facts. Chemical philosophy makes abstract the special properties of bodies it is composed of the general study of the material particles chemists call atoms and the forces to which these particles are submitted. 22... 

Diamond is a material possessing unique properties. It has extraordinarily high atomic density, hardness, insulating ability, thermal conductivity, and chemical inertness (see Table 1). The history of its intensive electrophysical, physico-chemical, and optical studies covers many decades [1, 2], Its applications in materials science [3], microelectronics [4], and so on, are ever widening. 

No alchemist in history ever thought the Secret Art was solely a mental discipline. The work of transformation takes place in the real world. Yet alchemy is not chemistry. Chemistry is a superficial science that deals only with the external forms in which the elements manifest. A chemist seeks to rearrange atoms and molecules to exhibit different properties of the same dead material. An alchemist seeks to create an entirely new substance by exposing its essences, bringing them alive, and causing them to grow.

Many body potentials e.g. Sutton-Chen, Tersoff, " Brenner can be used to describe metals and other continuous solids such as silicon and carbon. The Brenner potential has been particularly successful with fullerenes, carbon nanotubes and diamond. Erhart and Albe have derived an analytical potential based on Brenner s work for carbon, silicon and silicon carbide. The Brenner and Tersolf potentials are examples of bond order potentials. These express the local binding energy between any pair of atoms/ions as the sum of a repulsive term and an attractive term that depends on the bond order between the two atoms. Because the bond order depends on the other neighbours of the two atoms, this apparently two-body potential is in fact many-body. An introduction and history of such potentials has recently been given by Finnis in an issue of Progress in Materials Science dedicated to David Pettifor. For a study of solid and liquid MgO Tangney and Scandolo derived a many body potential for ionic systems. 

The Science Museum Library in South Kensington has a long history but its loan service is of more recent date. Its collection of material on the history of science and technology is of great importance. Total holdings of periodicals number about 25,000 of which over 10,000 are current. The library is an official depository for British patent specifications and atomic energy reports. Its stock, which approaches half a million volumes, is...
