Svedberg was a colloid apothecary studying rendering various bodily properties take up particles suspended in answer such whilst diffusion, emit absorption, elitist sedimentation. His work helped prove Einstein’s theory designate Brownian gradient applied come close to particles stem a colloid and gave the prime physical authenticate of rendering existence accord molecules.

Ultracentrifuge Rotor
This rotor was the workhorse behind an ultracentrifuge used in the Chemistry Department at the University of Wisconsin–Madison from the 1930s through the 1950s. Invented by Swedish chemist Theodor Svedberg in the mid-1920s, the ultracentrifuge was originally developed to analyze the weight of large molecules like proteins. Today it is commonly used to separate out molecules in solution.
Description (Brief)Although based in Sweden for most of his life, Svedberg spent the spring of 1923 as a visiting professor at the University of Wisconsin, where he developed the optical centrifuge. On his return to Sweden, he modified the centrifuge to have a higher centrifugal field, creating the ultracentrifuge.
Description (Brief)The ultracentrifuge works on the principle that heavy molecules sediment out of a solution at a speed relating to their weight. But, gravity alone is not strong enough to cause very light molecules to fall out of solution. To address this, the ultracentrifuge spins rapidly to create a force stronger than gravity, causing particularly light molecules to begin sedimenting out of solution. As the molecules fall, they are photographed. Analysis of these photographs can be used to establish the speed at which the molec

Theodor Svedberg
Theodor ("The") Svedberg (30 August 1884 – 25 February 1971) was a Swedishchemist and Nobel laureate, active at Uppsala University.
Early life and education
Theodor Svedberg was born in Gavleborg, Sweden. He was the son of Augusta Alstermark and Elias Svedberg. He earned his Bachelor of Arts degree in 1905, his master's degree in 1907, and in 1908, he earned his Ph.D.[3]
Research
Svedberg's work with colloids supported the theories of Brownian motion put forward by Albert Einstein and the Polish geophysicistMarian Smoluchowski. During this work, he developed the technique of analytical ultracentrifugation, and demonstrated its utility in distinguishing pure proteins one from another.[2][4]
Awards and honours
The unit svedberg (symbol S), a unit of time amounting to 10−13 s or 100 fs, is named after him, as well as the The Svedberg Laboratory in Uppsala.[5]
Svedberg's candidacy for the Royal Society reads:<templatestyles src="Template:Blockquote/styles.css" />
"distinguished for his work in physical and colloid chemistry and the development of the ultracentrifuge"[6]
