Learning Physics, Metaphors, and Quantum Fields

In my series on Quantum Field Theory I wanted to document my own learning endeavors but it has turned into a meta-contemplation on the 'explain-ability' of theoretical physics. Initially I had been motivated by a comment David Tong made in his introductory lecture: Comparing different QFT books he states that Steven Weinberg's books are hard reads because at … Continue reading Learning Physics, Metaphors, and Quantum Fields

And Now for Something Completely Different: Quantum Fields!

Do I miss assignments and exams? Definitely not, and I am now - finally, really, absolutely - determined to complete another program I had set for myself about 2-3 years ago. I had not been able to pull it off in addition to being a moonlighting student. Since about 10 years I have been recycling my physics knowledge on … Continue reading And Now for Something Completely Different: Quantum Fields!

Why Fat Particles Radiate Less

I am just reading Knocking on Heaven's Door by Lisa Randall which has a chapter on the impressive machinery of Large Hadron Collider. The LHC has been built to smash proton beams against each other: Protons, not electrons. Why protons? I stumbled upon the following statement: "But accelerated particles radiate, and the lighter they are, the more they do … Continue reading Why Fat Particles Radiate Less
