# Quantum Field Theory with Dr. Rodeny A. Brooks

## Dr. Rodney A. Brooks

Rodney A. Brooks was born in Syracuse, NY, in 1932. He attended the University of Florida and Harvard University, where he received his Ph.D. in physics with Nobel laureate Norman Ramsey in 1963. At that time he was fortunate to learn Quantum Field Theory from its perfector, Nobel laureate Julian Schwinger, who had just published his five-paper series "The theory of quantized fields", in which matter fields are treated for the first time on an equal basis with force fields. After several years as a post-doc at Harvard, Brooks spent five years working on aerospace projects. Then in 1970 he changed to the field of medical research. This led to a 25-year career at the National Institutes of Health, where he published 124 refereed articles. Among his accomplishments was construction of the highest resolution PET scanner of its time, the "Neuro-PET". He also invented dual-energy computed tomography (US patent 4247774), a method which has now been incorporated into commercial scanners. As an amateur clarinetist he founded and led a klezmer band called Shir Delite. After moving to New Zealand when he retired, he became aware that the wonderful QFT that he had learned from Schwinger is largely forgotten or misunderstood, leaving the lay public to founder in the weirdness and paradoxes of Quantum Mechanics and Relativity. He then made it his retirement mission to tell the people about QFT - the only theory that makes sense.

### Particles vs. Fields - A Battle of Three Rounds

12:38

Almost a hundred years ago a physics theory emerged known as quantum mechanics. From the beginning, quantum mechanics, a theory based on particles, was plagued with weirdness and mystery. A bit later quantum field theory was developed, describing a world made of fields, not particles. After a battle of three rounds, quantum mechanics emerged as the victor, unfortunately, and today the paradoxes of quantum mechanics permeate our culture, from movies to comic strips. This video describes the "slugfest" between quantum mechanics and quantum field theory, as Prof. Edward Finn and Dr. Rodney Brooks put on the gloves and show why quantum field theory is still the best way to understand physics.

16:16

Physicists Edward Finn and Rodney Brooks take on the task of describing quantum field theory to laypersons without using any math. They describe the six basic quantum fields, and show how the field picture, and only the field picture, enables a true understanding of physics.

8:24

Dr. Rodney Brooks shows why the Higgs boson is a field, not a particle. To be more specific, the Higgs boson is a quantum of the Higgs field. In fact, the discovery of the Higgs boson is a final piece of evidence that validates quantum field theory, a theory that is often misunderstood or neglected.

50:18

Most people are baffled by "Einstein's Enigmas" - special relativity, general relativity, and quantum mechanics. Yet understanding these mysteries is within everyone's grasp, once it is recognized that the universe is made of fields, not particles. The paradoxes of Einstein's theories of relativity and quantum mechanics (of which Einstein was the "grandfather") become simple consequences of the way fields behave. http://www.quantum-field-theory.net/### What Does the Electron Look Like?

34:27

"What Does the Electron Look Like": a talk at the Czech Technical University in Prague by Rodney A. Brooks, author of "Fields of Color: The theory that escaped Einstein" http://www.quantum-field-theory.net. Dr. Brooks shows why the field picture of the electron is much more satisfactory than the particle picture.### Understand Quantum Field Theory

57:52

In a talk at Georgetown University, Dr. Rodney Brooks, author of "Fields of Color: The theory that escaped Einstein", shows why the answer is quantum field theory. He shows how quantum field theory, so often overlooked or misunderstood, resolves the weirdness of quantum mechanics and the paradoxes of relativity . Once the concepts of quantum field theory are grasped, understanding physics is within anyone's grasp.

12:07

Are you trying to understand physics? Understanding physics should not be that difficult. Dr. Brooks' book titled "Fields of Color" will help you understand physics. This video covers a 12-minute interview in which Dr. Rodney Brooks compares and contrasts quantum mechanics with quantum field theory.
