This is a general Science discussion which will be updated from time to time.
First of all the “health warning”
I used to be a Physicist a long time ago. I keep up with my subject mainly by reading New Scientist. I make no claims to accuracy in this post and would be delighted to hear from anybody who can put me right. I will have a go at answering questions, again, with the proviso that the answers might also be wrong.
To get things going I have written three short pieces on topics about which I have been thinking about.Almost on cue 100 years after the publication of the General Theory of Gravitation by Albert Einstein the theory as been vindicated by the detection of
Clearly there are a large number of “triumphs” for modern theoretical physics .But all is not as perfect. Sometimes theory does not fit with observations and Physicists need to invent all kinds of stuff and then worry about detecting it.Here is an example of what some may regards as a bit of a “bodge”
Physicists do their physics in a large number of different ways Some of us try and get most of the way towards an answer by waving our arms about (plausibility argument) and then when we think we have it we go back and to it properly.(This what appears in the journals).Some of us when waving our arms about like to invoke something called symmetry. Here is an example of how far you can get like this.
Billiards and Why We Are Here
I found this clip after I’d written the stuff about billiards and was slightly pleased that it was saying the same thing only better and a bit more .
It says maybe there is just one electron in the universe
