Technology is defined as the application of that scientific knowledge to create devices that solve problems and carry out tasks.

According to science, technology is the study of the world and how it works through collecting data using the scientific method.


A nuclear weapon (additionally referred to as an atom bomb, atomic bomb, nuclear bomb, or nuclear warhead, and colloquially as an A-bomb or nuke) is an explosive tool that derives its negative pressure from nuclear reactions, both fission (fission bomb) or a mixture of fission and fusion reactions (thermonuclear bomb). Both bomb sorts launch massive portions of strength from notably small quantities of matter.

Nuclear weapons have helped us develop new technologies in other areas. The destructive power of nuclear weapons is well known, but the concepts of fission and fusion have helped us develop different technologies in different industries over a year.

Nuclear weapons produce tremendous explosive strength. It derives its detrimental pressure from nuclear reactions, both fission (fission bomb) or an aggregate of fission and fusion reactions (thermonuclear bomb). Both bomb sorts launch massive portions of strength from pretty small quantities of matter. A nuclear tool no large than a traditional bomb can devastate a whole town through blast, fire, and radiation. Nuclear guns generation turned into advanced for the duration of the Nineteen Thirties and 1940s. The United States detonated the primary nuclear guns over Hiroshima and Nagasaki, Japan in August 1945 and had been bombs brought through aircraft. Later, warheads had been advanced for strategic ballistic missiles, which have grown to be through a long way the maximum critical nuclear guns. Smaller tactical nuclear guns have also been advanced, including artillery projectiles, land mines, antisubmarine intensity charges, torpedoes, and shorter-variety ballistic and cruise missiles. As of now, controlling the manufacturing of nuclear guns has been a critical problem in worldwide relations.

The fundamental forms of nuclear guns are the Atomic bombs that are primarily based totally on the precept of nuclear fission and the Hydrogen bomb which makes use of the precept of nuclear fusion. All present nuclear guns get a number of their explosive electricity from nuclear fission reactions. Weapons whose explosive output is completely from fission reactions are generally referred to as atomic bombs or atom bombs (abbreviated as A-bombs). Nuclear fission is the system with the aid of using which the nucleus of an atom is struck with the aid of using a neutron and splits into smaller atoms. This system, which releases huge quantities of electricity, became at the start determined with the aid of using the Italian physicist, Enrico Fermi withinside the 1930s. Eventually, extra studies added approximately the invention that nuclear fission creates huge quantities of electricity and that if one atom underwent nuclear fission, it’d create a sequence response of nuclear fissions to a few of the surrounding atoms. This new technology helped to create the primary form of a nuclear weapon: the atomic bomb which makes use of radioactive isotopes (fissile substances).

The radioactive isotope is pressured to permit an exponential increase of nuclear chain reactions both with the aid of using taking pictures of one piece of sub-crucial fabric into another (the “gun” method) or with the aid of using compression of a sub-crucial sphere or cylinder of fissile fabric the usage of chemically-fueled explosive lenses (the “implosion” method). The latter technique is extra cutting-edge and efficient (smaller, much less massive, and requires much less luxurious fissile fuel) than the former. The maximum generally used fissile substances for nuclear guns programs had been uranium-235 and plutonium-239. Uranium-233 is much less generally used. Neptunium-237 and a few isotopes of americium can be used for nuclear explosives as well, however, it isn’t clear that this has ever been implemented, and their feasible use in nuclear guns is an issue of dispute. The quantity of electricity launched with the aid of using fission bombs can variety from the equal of simply below a ton to upwards of 500,000 tons (500 kilotons) of TNT (4.2 to 2.1×106 GJ).

A foremost task in all nuclear weapon designs is to make certain that a substantial fraction of the gasoline is eaten up earlier than the weapon destroys itself. All fission reactions generate fission merchandise, the stays of the break up atomic nuclei. Many fission merchandise is both relatively radioactive (however short-lived) or fairly radioactive (however long-lived), and as such, they’re a critical shape of radioactive contamination. Fission merchandise is the primary radioactive factor of nuclear fallout. Another supply of radioactivity is the burst of unfastened neutrons produced via way of means of the weapon. When they collide with different nuclei withinside the surrounding material, the neutrons transmute the one’s nuclei into different isotopes, changing their balance and making them radioactive.

Nuclear fusion is the technique wherein smaller nuclei crash into every different at one of this excessive pace that they fuse collectively developing considerable quantities of power. It became located withinside the 1940s after scientists including F.W. Aston and Sir Arthur Edington said that the power created via way of means of the solar is associated with nuclear fusion. Edward Teller, frequently known as the “father of the hydrogen bomb” created the primary hydrogen bomb, which became detonated on November 1, 1952, at Enewetak Atoll primarily based totally on the discoveries of Aston and Sir Edington. The hydrogen bomb, additionally referred to as a thermonuclear bomb, works the usage of the procedures of nuclear fission and fusion.

First, an atomic explosion happens the usage of the precept of the atomic bomb, wherein a bullet of U-235 rams into a bigger mass of U-235, developing nuclear fission withinside the bomb that reasons an explosion, which generates sufficient warmth for nuclear fusion to take place.

The nuclear war approach is fixed of regulations that address stopping or combating a nuclear war. The coverage of looking to save you an assault via way of means of a nuclear weapon from every other USA via way of means of threatening nuclear retaliation is called the approach of nuclear deterrence. The purpose of deterrence is to constantly preserve a 2d strike capability (the cap potential of a rustic to reply to a nuclear assault with one in every of its own) and doubtlessly to try for first strike status (the cap potential to wreck an enemy`s nuclear forces earlier than they may retaliate). During the Cold War, coverage and army theorists have taken into consideration the types of regulations that could save you a nuclear assault, and that they advanced recreation principle fashions that would cause solid deterrence conditions.

The now decommissioned United States’ Peacekeeper missile changed into an ICBM advanced to update the Minuteman missile withinside the overdue 1980s. Each missile, just like the heavier elevated Russian SS-18 Satan, may want to incorporate up to 10 nuclear warheads (proven in red), every of which may be aimed toward a specific target. A thing withinside the improvement of MIRVs changed into to make entire missile protection tough for an enemy the USA

Isotopes of hydrogen, specially H-2 (Deuterium) and H-3 (Tritium) are fused collectively below this extreme warmth. The power from all of the isotopes of hydrogen fusing collectively produces a tremendous quantity of power, making a good extra huge explosion than the atomic bomb.

Hydrogen bombs are over a thousand instances extra explosive than atomic bombs and are the maximum detrimental guns ever known.

Only six countries—the United States, Russia, United Kingdom, China, France, and India—have performed thermonuclear weapon tests. The declaration that India has detonated a “true” multi-staged thermonuclear weapon is debatable. North Korea claims to have examined a fusion weapon as of January 2016, even though this declaration is uncertain. Thermonuclear guns are stated to be a great deal extra hard to layout and execute than primitive fission guns. Presently, nearly all nuclear guns use the thermonuclear layout due to the fact it’s far extra efficient.

Alternatively, extra fusion stages—every degree igniting a bigger quantity of fusion gasoline withinside the subsequent degree can be included. This method may be used to assemble thermonuclear guns of very huge yield. This is in evaluation to fission bombs, which can be confined of their explosive strength because of a chance of criticality (untimely nuclear chain response due to too-huge quantities of pre-assembled fissile gasoline). The biggest nuclear weapon ever detonated called the Tsar Bomba of the USSR, which launched a strength equal to over 50 megatons of TNT (210 PJ), became a three-degree weapon. Most thermonuclear guns are substantially smaller than this, because of realistic constraints from missile warhead area and weight requirements.

Fusion reactions do now no longer create fission products, and for that reason make a contribution some distance much less to the introduction of nuclear fallout than fission reactions, however, due to the fact all thermonuclear guns incorporate as a minimum one fission degree, and plenty of excessive-yield thermonuclear gadgets have a very last fission degree, thermonuclear guns can generate as a minimum as a great deal nuclear fallout as fission-most effective guns. Furthermore, excessive yield thermonuclear explosions (maximum dangerously floor bursts) have the pressure to raise radioactive particles upwards beyond the tropopause into the stratosphere, wherein the calm non-turbulent winds allow the particles to tour outstanding distances from the burst, ultimately settling and unpredictably contaminating regions some distance eliminated from the goal of the explosion.

The machine used to supply a nuclear weapon to its goal is a vital element that influences each nuclear weapon’s layout and nuclear strategy. The layout, improvement, and protection of transport structures are most of the maximum luxurious components of a nuclear guns program; they account, for example, for 57% of the monetary assets spent with the aid of using the US on nuclear guns tasks because 1940.

The best approach for turning in a nuclear weapon is a gravity bomb dropped from aircraft. This approach locations few regulations on the scale of the weapon. It does, however, restrict assault variety, reaction time to an imminent assault, and the wide variety of guns that a rustic can area on an equal time. With miniaturization, nuclear bombs may be introduced with the aid of using each strategic bomber and tactical fighter-bomber. This approach is the number one approach of nuclear guns transport; the bulk of U.S. nuclear warheads, for example, are free-fall gravity bombs, particularly the B61.

Preferable from a strategic factor of view is a nuclear weapon set up on a missile, that may use a ballistic trajectory to supply the warhead over the horizon. Although even short-variety missiles permit for a quicker and much less prone assault, the improvement of long-variety intercontinental ballistic missiles (ICBMs) and submarine-released ballistic missiles (SLBMs) has given a few international locations the cap potential to plausibly supply missiles everywhere in the globe with an excessive probability of success.

More superior structures, along with a couple of independently targetable reentry vehicles (MIRVs), can release a couple of warheads at exclusive objectives from one missile, decreasing the hazard of successful missile defense. Today, missiles are maximum not unusual place amongst structures designed for the transport of nuclear guns. Making a warhead small sufficient to in shape onto a missile, even though it, maybe hard.

Tactical guns have worried the maximum style of transport types, such as now no longer most effective gravity bombs and missiles however additionally artillery shells, land mines, and nuclear intensity costs and torpedoes for anti-submarine warfare. An atomic mortar has been examined with the aid of using the US. Small, two-guy transportable tactical guns (extremely misleadingly known as suitcase bombs), along with the Special Atomic Demolition Munition, had been developed, even though the issue of mixing enough yield with portability limits their navy utility.

Different kinds of nuclear weapons transport permit for one-of-a-kind styles of nuclear strategies. The dreams of any approach are common to make it hard for an enemy to release a pre-emptive strike in opposition to the weapon device and hard to guard in opposition to the transport of the weapon at some stage in a capacity conflict.
