A Short Break-Down of Maxwell's Equations


Maxwell's equations are used describe electricity and magnetism. The first two tell us about electric and magnetic effects, but the last two are the most important because they unite electricity and magnetism; hence, “electromagnetism". Their initial state are integrals in the form of differential equations in which you NEED to actually learn about how those animals are derived into standard form because they might not make any sense to you now. However, we can peek into what these equations mean. Differential equations break down into functions. They are basically relations where big functions spit out smaller functions and yield general solutions, and with a little more work, particular solutions. These relations basically state that moving charges generate magnetic fields and changing magnetic fields create changing electric fields.

A Dynamical Theory of the Electromagnetic Field is the third of James Clerk Maxwell's papers regarding electromagnetism, published in 1865. It is the paper in which the original set of four Maxwell's equations first appeared. The concept of displacement current, which he had introduced in his 1861 paper On Physical Lines of Force, was utilized for the first time, to derive the electromagnetic wave equation. But now for the details…

A Course on AdS/CFT (2013)

This is a PhD level course, designed for second year PhD students in Theoretical High Energy Physics (HEP-TH) area and assumes a background knowledge of Quantum Field Theory at the level of Peskin-Schroder book and General Relativity. It would be great if the audience are already familiar with basics of CFT’s and black hole physics.

Link to course


                                               Topics to be discussed in the course


1. AdS/CFT, a historical view on its stringy perspective.
2. AdS/CFT, formal statement, establishing the duality.
3. AdS/CFT, a tool for strongly coupled QFTs.
4. AdS/CFT, a tool for studying quantum gravity, discussing in brief  the general picture AdS/CFT has to offer for quantum gravity, quantum spacetime and quantum aspects of black holes.

With Don Lincoln on SUSY and a career in big science

- Mar 1st, 2014 by Alma Ionescu

Don Lincoln is now a senior physicist at Fermi National Accelerator Laboratory and splits his research time studying data from the Fermilab Tevatron and from the CERN Large Hadron Collider, located outside Geneva Switzerland. 

He is co-author of over 500 scientific publications that range over subjects from microscopic black holes and extra dimensions to the elusive Higgs boson.  His two most noteworthy scientific accomplishments include being part of the teams that discovered the top quark and what is likely to be the Higgs boson.

When Dr. Lincoln isn’t exploring the energy frontier, he enjoys communicating the excitement of his cutting edge research with the public. He is a popular writer because of his ability to explain fundamental particle physics in a deeply meaningful way and because of his fine sense of humor. So far he published two books which have been translated into Polish, Russian, German and Chinese. “Understanding the Universe: From Quarks to the Cosmos” and “The Quantum Frontier: The Large Hadron Collider” explain particle physics for the public. His third book (Alien Universe: Extraterrestrials in our Minds and in the Cosmos) combines astrobiology and popular reports of alien visitation to weave together a complete tale of the possibility of life from other planets.
