Portrait of Gunnar Källén: A Physics Shooting Star and Poet by Cecilia Jarlskog (auth.), Cecilia Jarlskog (eds.)

By Cecilia Jarlskog (auth.), Cecilia Jarlskog (eds.)

Wolfgang Pauli noted him as 'my discovery,' Robert Oppenheimer defined him as 'one of the main talented theorists' and Niels Bohr came across him greatly stimulating. Who was once the fellow in query, Gunnar Källén (1926-1968)?

His visual appeal within the physics sky was once like a taking pictures big name. His contributions to the clinical debate triggered pleasure between old and young. just like his pal and mentor, Wolfgang Pauli, he demanded honesty and rigor in physics - a different dividing line among truth and hypothesis. In his obituary, Arthur S. Wightman could write: 'Gunnar Källén used to be a proud continuer of the culture in quantum box thought tested via Wolfgang Pauli. His papers on quantum electrodynamics within the interval 1950-1954 carried the non-perturbative method of quantum electrodynamics ahead to some degree past which little or no crucial development has been made as much as the current day. on the time i used to be attempting to puzzle out the grammar of the language of quantum box concept, and the following used to be Källén already writing poetry within the language!'. as well as being a outstanding scientist, Källén had a truly attention-grabbing character, really worth exploring.

In her ebook, physicist Cecilia Jarlskog lines either the private and medical trajectory of this unsung hero of the early days of high-energy physics and quantum box concept. a few invited contributions via contributors of the Källén family members and extraordinary researchers from the sector, them all individually familiar with Källén, mix to shape an real portrait of the researcher and the fellow.

Last yet now not least, the reader becomes familiar with a few points of the background of particle physics in these days, as similar by means of Källén and those that corresponded with him. A commented collection of his most crucial and never simply available papers is incorporated as an extra bonus for specialists.

Granular Gases

"Granular Gases" are diluted many-particle structures within which the suggest loose course of the debris is way higher than the common particle measurement, and the place particle collisions happen dissipatively. The dissipation of kinetic power may end up in results akin to the formation of clusters, anomalous diffusion and attribute surprise waves to call yet a couple of.

Molecular Magnets: Physics and Applications

This publication presents an outline of the actual phenomena chanced on in magnetic molecular fabrics over the past two decades. it truly is written by way of prime scientists having made crucial contributions to this energetic zone of analysis. the most themes of this e-book are the rules of quantum tunneling and quantum coherence of single-molecule magnets (SMMs), phenomena which transcend the physics of person molecules, akin to the collective habit of arrays of SMMs, the physics of one-dimensional single–chain magnets and magnetism of SMMs grafted on substrates.

Example text

L. Hulthén, Opening Address at the above Symposium 3 Two Men of Utmost Importance: Pauli and Gustafson In this chapter we wish to introduce two men who played a crucial role in shaping up Källén’s academic career. They were: Wolfgang Pauli (1900–1958) who hardly needs any introduction. There is a great deal of information about him on the internet, the reason only partially being that he is a Nobel Laureate – he was in addition a very colorful character. Though this book is not about him, our readers will find him all over in it.

Ekspong (born 1922) chaired this committee. Ekspong has played a vital role in the development of experimental particle physics in Sweden and has chaired several important committees, such as the CERN Scientific Policy Committee and the Nobel Committee for Physics. 28 Portrait of Gunnar Källén References 1.

In addition there are two more volumes covering other historical aspects of this Organization.

This was on a Friday afternoon. Källén looked truly happy, as if solving this problem was going to give him much pleasure during the week-end. Indeed, on the following Monday, he presented the solution, having used a “magic” trick. His answers to the questions he got were sometimes quite long, containing several pages of calculations. He could be very blunt. If he thought a paper was not worth publishing he would say so and if the author nonetheless published the work and thus “made a fool of himself ” that was his problem.
