Welcome to the chemistry portal. Chemistry is a branch of science. Modern chemistry focuses on the study of elements of the world and the bonds between elements. Chemistry also deals with composition, structure, and properties of substances and the transformations that they undergo.The study of chemistry can help people to make new materials. In the study of matter, chemistry also investigates its interactions with energy and itself. Because of the diversity of matter, which is mostly in the form of compounds, chemists often study how atoms of different chemical elements interact to form molecules, and how molecules interact with each other.

Here, the sparks generated by striking steel against a flint provide the activation energy to initiate combustion in a Bunsen burner. The blue flame will sustain itself after the sparks are extinguished because the continued combustion of the flame is now energetically favorable.

 Many chemists have an interest in the history of chemistry. Those with philosophical interests will be interested that the philosophy of chemistry has quite recently developed along a path somewhat different from the general philosophy of science. Other articles that might interest you are: There is a Wikipedia Project on the History of Science and a portal for the philosophy of science. Wikipedia:WikiProject Chemicals/Data is a collection of links and references that are useful for chemistry-related works. This includes free online chemical databases, publications, patents, computer programs, and various tools. Science is Fun University of Wisconsin–Madison Chemistry Professor Bassam Z. Shakhashiri, shares the fun of science. unit-conversion.info A good place to figure out what equals what.

Hermann Emil Fischer (1852-1919) was a German chemist, and recipient of the Nobel Prize for Chemistry in 1902. Many consider Fischer to be the most brilliant chemist who ever lived, because of his numerous contributions to science, especially chemistry and biochemistry. Among these is his discovery of phenylhydrazine. He also undertook vast studies on purines. This work showed that various substances such as adenine, xanthine, caffeine, uric acid, and guanine, all belonged to one homogeneous family, and could be derived from one another. He reasoned this to be due to their common origins from a parent molecule, a bicyclic nitrogenous structure into which the characteristic urea group entered. Fischer regarded this structure as hypothetical, and named it 'purine' in 1884. He synthesised it in 1898. He is also famed for his work on sugars.
