I am reading three online resources in parallel - on the history and the basics of computing, computer science, software engineering, and the related culture and 'philosophy'. An accidental combination I find most enjoyable. Joel on Software: Joel Spolsky's blog - a collection of classic essays. What every developer needs to know about Unicode. New terms … Continue reading Computers, Science, and History Thereof
Math blogger Joseph Nebus does another A - Z series of posts, explaining technical terms in mathematics. He asked readers for their favorite pick of things to be covered in this series, and I came up with General Covariance. Which he laid out in this post - in his signature style, using neither equations nor … Continue reading Learning General Relativity
Some years ago I was busy with projects that required a lot of travelling but I also needed to stay up-to-date with latest product features and technologies. When a new operating system was released a colleague asked how I could do that - without having time for attending trainings. Without giving that too much thought, and having my … Continue reading On Learning
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 … Continue reading “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 … Continue reading Learning Physics, Metaphors, and Quantum Fields
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 … Continue reading May the Force Field Be with You: Primer on Quantum Mechanics and Why We Need Quantum Field Theory
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 … Continue reading Space Balls, Baywatch and the Geekiness of Classical Mechanics
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!
