Let’s Discuss the Lorentz Transforms – Part the Last: The Real Derivation, or The Nail in the Casket

In this post there are a lot of references to the previous one – it is essential that you read it before getting down to this.In my previous posts (see the list below below) I tried to express my doubts whether there is a real physical substrate to the Lorentz transforms. The assumptions about the constancy of the speed of light, the homogeneity of space-time, and the principle of relativity... Read more â€ș

Let’s Discuss the Lorentz Transforms – Intermission: Rapidity, and What it Means

I thought my previous post rather funny, and was surprised seeing it initially receive so few views. I thought the entertainment flopped, but fortunately I was wrong. I therefore feel it my duty before my readers to address the subject of the Landau & Lifschitz proof of the invariance of the interval.You can find the summary of it in Wikipedia. Making their starting point the light-like interval always being equal... Read more â€ș

There is one only too obvious problem with relativity of simultaneity in the way it is normally introduced, and I have never found an answer to it – what’s more, I never read or heard anyone formulate it. I will be grateful for an enlightening discussion.The framework of the thought experiment introducing relativity of simultaneity is this. Two rays of light travel in opposite directions and reach their destination simultaneously... Read more â€ș

It's alive

I wonder why IT developer interviews are so strange most of the time. It feels as if the people are looking for computer science teachers, not engineers. All those theoretical questions that have no relation to the working reality. It is strange to be looking for eloquent teachers, who can perfectly explain any term or pattern, and then ask them to do the actual work. Maybe it is the imprint... Read more â€ș
