The discussion seeks sources for 1950s video lectures, specifically beyond fluid mechanics. A user mentions a link to MIT's site but clarifies they are looking for lectures on different subjects. The conversation indicates that some users have already found relevant videos elsewhere. The focus remains on locating diverse educational content from that era. Overall, the thread emphasizes the challenge of finding specific historical video lectures.

Does anyone know where I can find video lectures similar to
in that they are from the 1950's?
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
I am attempting to use a Raman TruScan with a 785 nm laser to read a material for identification purposes. The material causes too much fluorescence and doesn’t not produce a good signal. However another lab is able to produce a good signal consistently using the same Raman model and sample material. What would be the reason for the different results between instruments?
