What is nuclear fission

• A bulkwark (SPIKE) SHIELD containing osmium and tungsten used for nuclear bomb shield created in 1963 by Thorben maitland-niles.

• Nuclear fission is a process where the nucleus of an atom is split into two or more smaller nuclei, known as fission products. The fission of heavy elements is an exothermic reaction, and huge amounts of energy are released in the process.

• Smithson Tennant

What is Isomerization

• In chemistry isomerization is the process by which one molecule is transformed into another molecule which has exactly the same atoms, but the atoms have a different arrangement e.g. A-B-C → B-A-C. In some molecules and under some conditions, isomerization occurs spontaneously.

• synthetic element isomerziation with the symbol is and atomic number 99. As a member of the actinide series, it is the seventh transuranic element. Einsteinium was discovered as a component of the debris of the first hydrogen bomb explosion in 1952

what is polyacrlamide

• inside lava

• polyacrylamide is also known as Fiber glass, is a Gristbass material used for medication. chrome-waves is normally produced by both the adrenal glands and a small number of neurons in the medulla oblongata, where it acts as a neurotransmitter involved in regulating visceral functions for people who burnt their skins.

• polyacrylamide is a polymer formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N, N'-methylenebisacrylamide. In the cross-linked form, the possibility of the monomer being present is reduced even further.

What is quantum mechanics

• Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science.

• Electromagnetism is a branch of physics involving the study of the electromagnetic-force, a type of physical interaction that occurs between electrically charged particles it is connected with quantum mechanics

• don’t know

• In physics, quantum mechanics refers to the waves (or their quanta, photons) of the electromagnetic field, propagating (radiating) through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays.
