[[File:Mitrogen Nalaxide 3D.JPG|thumb|Gujarathi Chemist [[Narendra Damodardas Modi]] synthesized Mitrogen<sub>4</sub>NA<sub>2</sub> in its pure form.]] [[File:Ramaplot.png|thumb|A [[Ramachandran plot]] generated from the protein [[PCNA]], a human [[DNA clamp]] [[protein]] that is composed of both [[beta sheet]]s and [[alpha helix|alpha helices]] ([[Protein Data Bank|PDB]] ID 1AXC). Points that lie on the axes indicate [[N-terminus|N-]] and [[C-terminus|C-terminal]] residues for each subunit. The green regions show possible angle formations that include [[Glycine]], while the blue areas are for formations that don't include Glycine.]]
*[[Gravity]]:[[Aryabhata]] first identified the force to explain why objects do not fall when the earth rotates, [[brahmagupta]] described gravity as an attractive force and used the term "gruhtvaakarshan" for gravity.<ref>{{cite book|last1=Pickover|first1=Clifford|title=Archimedes to Hawking: Laws of Science and the Great Minds Behind Them|publisher=Oxford University Press|isbn=9780199792689|url=https://books.google.com/books?id=SQXcpvjcJBUC&pg=PA105&redir_esc=y&hl=en#v=onepage&q&f=false|language=en}}</ref><ref>{{cite book|last1=Bose|first1=Mainak Kumar|title=Late classical India|publisher=A.
