The twin paradox is connected to the special relativity but I wonder simply if one might construct the paradox (or something very similar) based on the Lorentz’ (and FitzGerald) work alone? Several ingredients in the paradox, time dilation and Lorentz contraction, are often mentioned with...

I am considering the magnitude of the gravitational redshift and I look at the process of a photon leaving an atom from the Sun. I am asking whether the processes in the atom, viewed as a clock, would lead us to conclude that the emitted photon, at the time of emission, would itself be...

Thanks That is really all I need. I don't think I would go into more finer details. That would require looking at the original article by Kretchmann , (Kretchmann, Das statische Einkörperproblem in der Einstein'schen Theorie. Antwort an Hrn. A. Gullstrand. Ark. för Mat., Astron, och Fys. 17...

First, regarding references. it is Aant Elzinga Einstein's Nobel Prize, A Glimpse Behind Closed Doors, Science History Publications, USA, 2006. He was granted access to the Nobel archives and I believe this is the most important study of Einstein's document in the NObel Archive.. (I was not...

I am referring to the situation 1915-1921 when the Nobel Prize physics committee was discussing relativity. St. John from Mount Wilson could not confirm the gravitational redshift. The Physics Committee report for 1918 notes that: “A most careful experimental test carried out at the Mount...

The answer is YES! that is what I wonder. Let me give you the background: The Nobel Prize physics committee was influenced by the physicists in Uppsala in the beginning of the 20th century, and the discipline was dominated by the so called Ångström dynasty of instrumentalists. Physics in...

For the observation of the gravitational redshift one needs an adaptation of the GTR of the object (related to the Sun´s gravity) and the observer (related to the Earth’s gravity). I assume that the situation is similar for the observation of the precession of Mercury, another experiment...

I take it then we should only expect one shift, i.e. any of the two, which you consider equivalent, and not two on top of each other.

My question is very simple (and I assume it has been discussed before but I cant't find the topic): An atom in the Sun emits a photon detected by an observer on Earth. Disregarding uncertainties and experimental problems relating to the movement of the atom (or assuming we could correct for...

I would certainly like for you to expand on the complexity of rational numbers (being an mathematical amateur in the first place). However, in my view you haven’t addressed my main question. I will therefore try to restate it more concisely (avoiding also constructability): The rationals...

Newer item: Springer published a free-downloadable book 2014 caled "Reflections on the Fukushima Daiichi Nuclear Accident" made as a result of a cooperation between Berkeley and Univ. of Tokyo.

I am considering the following question and I want you to agree (but perhaps you don’t):Rutherford wrote a letter to Bohr, as an answer to a previous letter from Bohr containing one of the first of Bohr’s descriptions of the atomic model, saying that he understood the atom model Bohr advocated...

Thank to all of you. I believe we may have come to the end of the road with this.

Thanks That sounds reasonable enough. Actually, I am mainly paraphrasing general explanations such a Wikipedia's (and many others): "In quantum mechanics, the uncertainty principle is any of a variety of mathematical inequalities asserting a fundamental limit to the precision with which...

Thank you for your interest. I was thinking along the following lines: i) first I considered how things, as I speculate, may have looked to Heisenberg initially, i.e. particles indeed have locations, energy etc. but it seems that for some combinations we may not be able to find a set of...
