As other authors of science blogs have pointed out: Most popular search terms are submitted by students. So I guess it is not the general public who is interested in: the theory of gyroscopes, (theory of) microwaves, (theory of) heat pumps, (theory of) falling slinkies, or the Coriolis force. I believe that these search terms […]Read More “Student Friendly Quantum Field Theory”
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 […]Read More Learning Physics, Metaphors, and Quantum Fields
All of old. Nothing else ever. Ever tried. Ever failed. No matter. Try again. Fail again. Fail better. This is a quote from Worstward Ho by Samuel Beckett – a poem as impenetrable and opaque as my post on quantization. There is a version of Beckett’s poem with explanations, so I try again, too! I […]Read More Hyper-Jelly – Again. Why We Need Hyperspace – Even in Politics.
Yes, this is a serious physics post – no. 3 in my series on Quantum Field Theory. I promised to explain what Quantization is. I will also argue – again – that classical mechanics is unjustly associated with pictures like this: … although it is more like this: This shows the timelines in Back to the […]Read More On the Relation of Jurassic Park and Alien Jelly Flowing through Hyperspace
As Feynman explains so eloquently – and yet in a refreshingly down-to-earth way – understanding and learning physics works like this: There are no true axioms, you can start from anywhere. Your physics knowledge is like a messy landscape, built from different interconnected islands of insights. You will not memorize them all, but you need […]Read More May the Force Field Be with You: Primer on Quantum Mechanics and Why We Need Quantum Field Theory

Over on Elkement’s blog, Theory and Practice of Trying To Combine Just Anything, is the start of a new series about quantum field theory. Elke Stangl is trying a pretty impressive trick here in trying to describe a pretty advanced field without resorting to the piles of equations that maybe are…
This is the first post in my series about Quantum Field Theory. What a let-down: I will just discuss classical mechanics. There is a quantum mechanics, and in contrast there is good old classical, Newtonian mechanics. The latter is a limiting case of the former. So there is some correspondence between the two, and there are rules […]Read More Space Balls, Baywatch and the Geekiness of Classical Mechanics
