An alternative way of making an alloy is to turn the components into powders, mix them together, and then fuse them with a combination of high pressure and high temperature. This technique is called powder metallurgy. A third method of making alloys is to fire beams of ions (atoms with ...
The force that holds protons and neutrons together is, not for nothing, called the strong nuclear force. The nuclei of atoms can be regarded, in a sense, of sitting at the center of all matter, so their extreme stability makes sense in a cosmos rife in organization and capable of sustaini...

Accordingly, let us define the -entropy of the seminorm to be the least cardinality of for which such an inverse theorem holds. Seminorms with low entropy are ones for which inverse theorems can be expected to be a useful tool. This concept arose in some discussions I had with Ben Green...
freed from atomic nuclei. Researchers use electric and magnetic fields to control the resulting collection of ions and electrons because they have electrical charges. At sufficiently high temperatures, ions can overcome repulsive electrostatic forces and fuse together. This process—fusion—releases energy...
