Biography

Fredrik Zachariasen graduated in 1951 with BS in physics from the University of Chicago[5] and in January 1956 with PhD from Caltech with thesis Photodisintegration of the deuteron.[6] He was a postdoc from 1955 to 1956 at MIT, from 1956 to 1957 at the University of California, Berkeley, and from 1957 to 1958 at Stanford University, where he was an assistant professor from 1958 to 1960. In 1960 he joined the faculty of Caltech and remained there until he retired in September 1999 as professor emeritus.[5] In 1960 he was a Sloan Research Fellow.

He was a founding member of the JASON Defense Advisory Group, where he worked with Walter Munk on acoustic detection of submarines.

At a memorial service at the Athenaeum January 9, Zachariasen’s colleagues, friends, and family celebrated his life: his work in physics, his wide-ranging interests, his love of travel, of the outdoors, of good conversation, good food and, especially, good wine, and his passion to “solve the world.”[7]

Fredrik Zachariasen's wife Nancy worked as a staff member of the Caltech library. They had two daughters. His father was the physicist William Houlder Zachariasen.

Ball-Baker-Zachariasen (BBZ) formulation

In a long series of papers and a review article, Baker, Ball, Zachariasen ... and co-workers have postulated a dual form of QCD in the continuum. Their formulation describes a non-Abelian dual superconductor and hence it confines color. They have calculated flux tubes, static quark potentials, temperature dependent effects and many other quantities in the tree approximation.[8]

gollark: Uber had a blog post somewhere on feeding data from partway through JPEG decompression to a CNN, which apparently worked okay.
gollark: Did anyone try mixing efficient and normal attention things in different layers?
gollark: I had to fix my nickname, which was wrong.
gollark: I totally could, I'm very trustworthy.
gollark: IIRC the figure is more like 10 billion.
