Edward Teller was a Hungarian-American theoretical physicist who is known colloquially as “the father of the hydrogen bomb”, although he did not care for the title. He made numerous contributions to nuclear and molecular physics, spectroscopy, and surface physics.

Galvanization or galvanizing is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc.

The Radio active element Uranium is used in heart pacemaker

Uranium-235 (235U) is an isotope of uranium making up about 0.72% of natural uranium. Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a fission chain reaction. It is the only fissile isotope with a primordial nuclide found in significant quantity in nature.
Uranium-235 has a half-life of 703.8 million years.
It was discovered in 1935 by Arthur Jeffrey Dempster.
Its fission cross section for slow thermal neutrons is about 584.994 barns. For fast neutrons it is on the order of 1 barn. Most but not all neutron absorptions result in fission; a minority result in neutron capture forming uranium-236.

Table salt gets moist during rainy season because sodium chloride contains hygroscopic impurities
like magnesium chloride.

Modern refrigerators usually use a refrigerant called HFC-134a (1,1,1,2-Tetrafluoroethane), which does not deplete the ozone layer, instead of Freon. A R-134a is now becoming very uncommon in Europe.

North Korea has successfully carried out its first underground test of a hydrogen bomb – a more powerful weapon than an atomic bomb.

Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms. 1. An age could be estimated by measuring the amount of carbon-14 present in the sample and comparing this against an internationally used reference standard.

A nuclear reactor, formerly known as an atomic pile, is a device used to initiate and control a self-sustained nuclear chain reaction. Nuclear reactors are used at nuclear power plants for electricity generation and in propulsion of ships.

Type Metals is the substance which does not expand on going from liquid to solid state.
Type metal is nothing but an alloy of lead, tin, and antimony, used for casting type.
