The law of the equivalence of mass and energy, expressed by E = mc2 or energy, is equal to the mass multiplied by the velocity of the square of light. They found that all the stars obeyed Einstein’s law concerning dark matter.

Nuclear fusion is a process by which many nuclei are interconnected, forming heavier nuclei. It is accompanied by the release or absorption of energy by the mass of the involved nuclei.

Danish astronomer Olaus Roemer, who first measured the speed of light in 1676 for the first time. His method was based on the observation of the eclipse of Jupiter’s satellites (Jupiter).

Isaac Newton published the complete theory of gravity in 1687. Although others already thought about this, Newton first created a method that applies to all objects, large and small, using mathematics in advance.

Sodium bicarbonate (IUPAC name: sodium bicarbonate), familiarly known as baking soda, it is a chemical compound with the formula NaHCO3.

Acid rains are caused by a chemical reaction that begins when compounds such as nitrogen oxides and sulfur dioxide are emitted into the air. These substances can rise extremely high in the atmosphere, where they are mixed and react with oxygen, water and other chemicals to form acidic pollutants called acid rain.

The atmosphere contains many gases, most of which are in small quantities, including pollutants and greenhouse gases. The most common gas in the atmosphere is nitrogen (78.08%).

Antoine Lavoisier is regarded to be the father of modern chemistry. He was a French nobleman who recognized and named oxygen and identified the main components of the air.

The fixation is usually achieved by treating a film or paper with a solution of thiosulfate salt. Popular salts are sodium thiosulfate, which is commonly called hypo.

John Dalton’s atomic theory was the first complete attempt to depict all matter in terms of atoms and their properties.
