NASA ISS in Real Time, exploring 25 years onboard the station
Too bad they are planning on crashing it into the ocean in the not too distant future. Seems like such a waste.- bob012345

Predictions for the Nobel Prize in Physics 2025 (results: John Clarke, Michel H. Devoret and John M. Martinis)
Ever solve a problem so well you feel like you deserve a prize? At least that’s what I got from it.- bob012345

B Need help understanding particle physics and quantum physics
To me the issue is not if there is physical reality underneath what are now labeled quantum fields. It is can quantum fields be measured as distinct physical entities and what are their properties as compared to mathematical representations in some theory which are assumed to be some fundamental...- bob012345

I Geometry problem of interest with a 3-4-5 triangle
The two solutions with square edges along the triangle sides cut the triangle into either two or three smaller 3-4-5 triangles. The case where only three points of the square touch the sides of the triangle cuts it into two triangles different from the 3-4-5 and one four sided shape.- bob012345

I Geometry problem of interest with a 3-4-5 triangle
I got the maximum and one relative maximum but missed the minimum. I had the diagonal of the square vertical which gives s=12/11 root(2).- bob012345

I Geometry problem of interest with a 3-4-5 triangle
It might be interesting to consider a square inscribed in a 3-4-5 triangle. If the square must touch all three sides, what is the largest, the smallest possible?- bob012345

I Geometry problem of interest with a 3-4-5 triangle
Apparently, this construction, the original square with semi-diagonals as @DaveC426913 drew in post #18, goes back thousands of years and has numerous properties of interest. There is a Wooden book called The Diagram all about it. This construction is also called the Helicon. Wooden books...- bob012345

Yes, I rounded it to fit the grids of the graph paper from 2.828 to 2.75 since the grids were quarter inch. Made the drawing a lot easier!- bob012345

It looks off but I computed the coordinates and checked the edge lengths which are ##2-√2##.- bob012345
