-- Vital secrets of Britain's first atomic submarine, the Dreadnought, and, by implication, of the entire United States navy's still-building nuclear sub fleet, were stolen by a London-based soviet spy ring, secret service agents testified today.

It has a hull patterned on that of the United States navy's Nautilus, the world's first atomic submarine.

The trial will be held, probably the first week of March, in the famous Old Bailey central criminal court where Klaus Fuchs, the naturalized British German born scientist who succeeded in giving American and British atomic bomb secrets to Russia and thereby changed world history during the 1950s, was sentenced to 14 years in prison.

Atomic timekeeping services started experimentally in 1955, using the first caesium atomic clock at the National Physical Laboratory, UK ( NPL ).

Nevertheless, in spite of Rutherford's estimation that gold had a central charge of about 100 ( but was element Z = 79 on the periodic table ), a month after Rutherford's paper appeared, Antonius van den Broek first formally suggested that the central charge and number of electrons in an atom was exactly equal to its place in the periodic table ( also known as element number, atomic number, and symbolized Z ).

Giesel, on the other hand, can rightfully be credited with the first preparation of radiochemically pure actinium and with the identification of its atomic number 89.

The first Abstract Expressionists were considered madmen to give up their brushes and rely on the sheer force of energy to leave an image, but then the import of atomic bombs, all atomic energy, became realized, and art found no better way of expressing its power.

The shapes of the first five atomic orbitals: 1s, 2s, 2p < sub > x </ sub >, 2p < sub > y </ sub >, and 2p < sub > z </ sub >.

Cysteine is unusual since it has a sulfur atom at the second position in its side-chain, which has a larger atomic mass than the groups attached to the first carbon, which is attached to the α-carbon in the other standard amino acids, thus the ( R ) instead of ( S ).

" Ever since the time of my ancestor Ali, the first Imam, that is to say over a period of thirteen hundred years, it has always been the tradition of our family that each Imam chooses his successor at his absolute and unfettered discretion from amongst any of his descendants, whether they be sons or remote male issue and in these circumstances and in view of the fundamentally altered conditions in the world in very recent years due to the great changes which have taken place including the discoveries of atomic science, I am convinced that it is in the best interest of the Shia Muslim Ismailia Community that I should be succeeded by a young man who has been brought up and developed during recent years and in the midst of the new age and who brings a new outlook on life to his office as Imam.

* 1949 – Soviet atomic bomb project: The Soviet Union tests its first atomic bomb, known as First Lightning or Joe 1, at Semipalatinsk, Kazakhstan.

* 1982 – The synthetic chemical element Meitnerium, atomic number 109, is first synthesized at the Gesellschaft für Schwerionenforschung in Darmstadt, Germany.

The first Soviet atomic device was tested on August 29, 1949.

The atom probe is closely related to the method of Field Ion Microscopy, which is the first microscopic method to achieve atomic resolution, occurring in 1951.

Thus the discovery report by the Berkeley group reads: " It is suggested that element 97 be given the name berkelium ( symbol Bk ) after the city of Berkeley in a manner similar to that used in naming its chemical homologue terbium ( atomic number 65 ) whose name was derived from the town of Ytterby, Sweden, where the rare earth minerals were first found.

While protons and neutrons combined to form the first atomic nuclei only a few minutes after the Big Bang, it would take thousands of years for electrons to combine with them and create electrically neutral atoms.

The Eastern leaders retaliated against these steps by integrating the economies of their nations in Comecon, their version of the Marshall Plan ; exploding the first Soviet atomic device in 1949 ; signing an alliance with People's Republic of China in February 1950 ; and forming the Warsaw Pact, Eastern Europe's counterpart to NATO, in 1955.

Chemical elements may also be categorized by their origin on Earth, with the first 98 considered to be naturally occurring, while those with atomic numbers beyond 98 have only been produced artificially as the synthetic products of man-made nuclear reactions.

Human technology has produced various additional elements beyond these first 98, with those through atomic number 118 now known.

In the early 1950s, the first semi-empirical atomic orbital calculations were carried out.

The determination of molecular structure by geometry optimization became routine only after efficient methods for calculating the first derivatives of the energy with respect to all atomic coordinates became available.

Given is each element's name, atomic number, year of first report, name of the discoverer, and some notes related to the discovery.

It was first believed the bomb was rigged to the car's starter.

For example, the analysis of the debris at the testing site of the first U. S. hydrogen bomb, Ivy Mike, ( 1 November 1952, Enewetak Atoll ), revealed high concentrations of various actinides including americium ; due to military secrecy, this result was published only in 1956.

After moving to Sarov in 1950, Sakharov played a key role in the development of the first megaton-range Soviet hydrogen bomb using a design known as " Sakharov's Third Idea " in Russia and the Teller-Ulam design in the United States.

The first use of an air-dropped bomb was carried out by the Italians, initially by Lieutenant Giulio Gavotti, in their 1911 war for Libya.

A hydrogen bomb — which produced nuclear fusion instead of nuclear fission — was first tested by the United States in November 1952 and the Soviet Union in August 1953.

Standard monetary bonuses are awarded for winning a round, losing a round, killing an enemy, being the first to instruct a hostage to follow, rescuing a hostage or planting ( Terrorist )/ defusing ( Counter terrorist ) the bomb.

* Canopus ( nuclear test ) was the name given to the first test of the French hydrogen bomb, in 1968, with a yield of 2. 8 megatons

Einsteinium was discovered as the debris of the first hydrogen bomb explosion in 1952, and named after Albert Einstein.

The test was carried out on November 1, 1952 at Enewetak Atoll in the Pacific Ocean and was the first successful test of a hydrogen bomb.

After the detonation of the first Soviet fission bomb in August 1949, he, along with Isidor Rabi, wrote a strongly worded report for the committee which opposed the development of a hydrogen bomb on moral and technical grounds.

On 2 December 1942 he initiated the atomic age with the first self-sustaining chain reaction, after which he became known as " father of the atomic bomb ".

It was discovered in the debris of the first hydrogen bomb explosion in 1952, and named after Nobel laureate Enrico Fermi, one of the pioneers of nuclear physics.

Fermium was first discovered in the fallout from the ' Ivy Mike ' nuclear test ( 1 November 1952 ), the first successful test of a hydrogen bomb .< ref name =" lanl ">

As an active military leader, Roosevelt implemented an overall war strategy on two fronts that ended in the defeat of the Axis Powers and the development of the world's first atom bomb.

In 1954, the island was destroyed by a hydrogen bomb test, just months before Godzilla first attacked Tokyo.

While no earthquake or tsunami followed the test, the opposition grew when the U. S. announced they would detonate a bomb five times more powerful than the first one.

During the siege, on 8 February 1913, the Russian pilot N. de Sackoff, flying for the Greeks, became the first pilot ever shot down in combat, when his biplane was hit by ground fire following a bomb run on the walls of Fort Bizani.

In 1994, IKEA ran a commercial in the United States widely thought to be the first commercial featuring a homosexual couple ; it aired for several weeks before being pulled due to bomb threats directed at IKEA stores.

Things changed in 1953 with the Soviet testing of their first hydrogen bomb, but it was not until 1954 that the Atlas missile program was given the highest national priority.
