Page "Lars Onsager" Paragraph 3

In 1925 he arrived at a correction to the Debye-Hückel theory of electrolytic solutions, to specify Brownian movement of ions in solution, and during 1926 published it.

He traveled to Zürich, where Peter Debye was teaching, and confronted Debye, telling him his theory was wrong.

He impressed Debye so much that he was invited to become Debye's assistant at the Eidgenössische Technische Hochschule ( ETH ), where he remained until 1928.
