Theodor Svedberg

Theodor Svedberg is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Theodor Svedberg rather than just read about it. In short: Theodor Svedberg (30 August 1884 – 25 February 1971) was a Swedish chemist and Nobel laureate for his research on colloids and proteins using the ultracentrifuge. Svedberg was active at Uppsala University from the mid-1900s to late 1940s.

Reference excerpt

Theodor Svedberg (30 August 1884 – 25 February 1971) was a Swedish chemist and Nobel laureate for his research on colloids and proteins using the ultracentrifuge. Svedberg was active at Uppsala University from the mid-1900s to late 1940s. While at Uppsala, Svedberg started as a docent before becoming the university's physical chemistry head in 1912. After leaving Uppsala in 1949, Svedberg was in charge of the Gustaf Werner Institute until 1967. Apart from his 1926 Nobel Prize, Svedberg was named a Foreign Member of the Royal Society in 1944 and became part of the National Academy of Sciences in 1945.

Early life and education Svedberg was born in Valbo, Sweden on 30 August 1884. He was the son of Augusta Alstermark and Elias Svedberg. Growing up, Svedberg enjoyed botany and other branches of science. While in grammar school, Svedberg conducted individual laboratorial research and performed scientific demonstrations. For his post-secondary education, Svedberg entered a chemistry program at Uppsala University in the early mid 1900s. He earned his Bachelor of Arts degree in 1905, his master's degree in 1907, and in 1908, he earned his Ph.D.

Career While at Uppsala, Svedberg started his scientific career in 1905 as an assistant chemist with the university. After becoming a chemistry docent for Uppsala in 1907, he became the university's physical chemistry head in 1912. For his academic tenure, Svedberg remained with Uppsala until 1949. During the early 1920s, he also temporarily taught for the University of Wisconsin. After leaving Uppsala, Svedberg led the Gustaf Werner Institute from 1949 to 1967.

Research Svedberg's work with colloids supported the theories of Brownian motion put forward by Albert Einstein and the Polish physicist Marian Smoluchowski. During this work, he developed the technique of analytical ultracentrifugation, and demonstrated its utility in distinguishing pure proteins one from another.

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 Svedberg Laboratory in Uppsala.

Svedberg's candidacy for the Royal Society reads:"distinguished for his work in physical and colloid chemistry and the development of the ultracentrifuge" Svedberg was elected an International Member of the American Philosophical Society in 1941. After becoming a Foreign Member of the Royal Society in 1944, Svedberg was named to the National Academy of Sciences in 1945. He was elected to the American Philosophical Society in 1948. From the 1910s to 1920s, Svedberg was awarded the Björkénska priset three times from Uppsala University for his contributions to science in Sweden. From the Franklin Institute, Svedberg was given the Franklin Medal in 1949 for his work with the ultracentrifuge.

Death and personal life On 25 February 1971, Svedberg died in Kopparberg, Sweden. He was married four times and had a total of twelve children.His widow died in 2019. He was a Lutheran

Worked examples

Example 1 — a first encounter with Theodor Svedberg

Start with the simplest possible case. Write down what Theodor Svedberg claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Theodor Svedberg before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Theodor Svedberg ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Theodor Svedberg

In research: Theodor Svedberg appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Theodor Svedberg in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Theodor Svedberg is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1884 births, 1971 deaths, Foreign members of the Royal Society, so understanding it makes those chapters shorter.
In everyday life: Look for Theodor Svedberg outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
