Ciro Santilli 37 Updated 2025-05-23 +Created 2024-07-12Ciro Santilli got his hands on this one. But he was unable to obtain the others. Solving them here would also pose a serious DMCA risk, so perhaps it's just not worth it.
William Coolidge explains medical imaging and X-rays (1940).
Source. Video sponsored by General Electric. A cool insight of this video is that a hot cathode is a more reliable electron source. Previous systems, and presumably including the discovery of X-rays, leftover gas in the tube was used. But this makes things more difficult to control, as we also want to remove as much gas as possible from the vacuum, otherwise electrons collide with the gas and lose energy before hitting the anode.How Does X ray Tube Works by BiomedEngg
. Source. Describes in particular the rotating cathode method. Interesting observation that this is especially important since the cathode cannot cool quickly due to the vacuum. PROMYS Europe application problem set by Ciro Santilli 37 Updated 2025-05-23 +Created 2024-07-12

Strongly against giving answer to problem sets... sad, as of 2024: promys-europe.org/students/faq (archive):and:It does not seem to be the case for the American version however after a quick look: promys.org/programs/promys/for-students/faq/. Sad to see.
When do I get the solutions to the problems on the problem sets?When you discover them for yourself: on your own or collaborating with other students. Returning students and counsellors and faculty will support and encourage you, but not by giving you the answers (hint: they don't even give hints). What PROMYS Europe does is offer you the tools and structure to enable you to be a creative mathematician.
What rules are there at PROMYS Europe?
Also participants are strongly forbidden from sharing the problem sheets with anyone from outside the program. Ciro Santilli asked a participant face to face if he could take a look, but was told that they are not allowed to share it. So it is a very clear and strict order. Truly sad.
There are unlisted articles, also show them or only show them.
