Fischer projections were originally proposed for the depiction of carbohydrates and used by chemists, particularly in organic chemistry and biochemistry. The use of Fischer projections in non-carbohydrates is discouraged, as such drawings are ambiguous and easily confused with other types of drawing. The main purpose of Fischer projections is ...
Hermann Emil Louis Fischer FRS FRSE FCS (German pronunciation: [ˈeːmiːl ˈfɪʃɐ] ⓘ; 9 October 1852 – 15 July 1919) was a German chemist and 1902 recipient of the Nobel Prize in Chemistry. He discovered the Fischer esterification. He also developed the Fischer projection, a symbolic way of drawing asymmetric carbon atoms. He also ...

This projection most commonly sights down a carbon-carbon bond, making it a very useful way to visualize the stereochemistry of alkanes. A Newman projection visualizes the conformation of a chemical bond from front to back, with the front atom represented by the intersection of three lines (a dot) and the back atom as a circle.

This meant that some British companies completely adopted third angle projection. BS 308 (Part 1) Engineering Drawing Practice, gave the option of using both projections, but generally, every illustration (other than the ones explaining the difference between first and third-angle) was done in first-angle.
The Robinson projection is an example of a pseudocylindrical projection. One of Robinson's most notable accomplishments is the Robinson projection . In 1961, Rand McNally asked Robinson to choose a projection for use as a world map that, among other criteria, was uninterrupted, [ 13 ] had limited distortion , and was pleasing to the eye of ...
