    Other I would like to get recommendations for graduate level physics books

    Most self-study efforts are aborted, no matter how confident the self-student is at the start. You even say in your post that you might not make it through your curriculum. I wouldn’t waste time on planning the graduate curriculum until you are nearing the end of your extensive undergrad review...

    How to measure the diameter of a shaft without a caliper?

    Harbor Freight has plastic composite digital calipers for $9.99. (They even have plastic manual-reading ones for $1.99!) Plenty accurate for your needs. Calipers link

    Other I would like to get recommendations for graduate level physics books

    Go through your seven review books first. You will then be in a much better position to evaluate what level of graduate text, and what style of exposition, works best for you going forward.

    Math Math major jobs in the space industry

    Pure math probably not much but if you are applied, you might have a shot. Numerical methods, writing or improving complex simulation codes for structural, thermal or electromagnetic systems, optimizations and, of course, anything AI.

    Undergrad Magnetic Resonance physics question: RF pulse role and 'in-phase'

    Information on spin dynamics is also in these classic texts: Abraham, Nuclear Magnetism Slichter, Principles of Magnetic Resonance EDIT: Spell check miscorrected the first name. It’s Abragam, not Abraham.

    Engineering Second degree for engineers for more job opportunities?

    Most job seekers complain that they follow hundreds of leads but rarely or never get an interview. The fact that you are getting many interviews indicates to me that your experience is in demand and that you are targeting the right companies and opportunities. It's hard to know what the issue...

    Job Skills Physics Careers: Expectations vs. Reality

    You've asked for a reality check. I find it sad to see how unrealistic your physics expectations are. You want support and free license to play, on your own terms in every way (you won't even move to follow an opportunity). The world doesn't work that way. Your notions about engineering are just...

    Announcement RIP Vanadium 50

    I miss his candor. How many times have we seen a post along the lines of "I'm a physics major at a lower ranked state college with a 2.4 GPA in my major. I have problems with [mental health/laziness/bad study habits/lack of motivation/addiction to video games] but I am set on doing my PhD in...

    What Happened to Talent?

    I Googled Autotune a while back and came across some YouTube videos of famous modern singers with apparently good voices, followed by videos of them caught singing in a casual setting (away from a studio) showing that they can’t carry a tune at all. It’s pretty disgraceful.

    Why Is Fan Suction/Intake So Weak Compared to Exhaust?

    Baluncore's comment is a large part of the answer. It is possible to have powerful air currents on the suction side by simply fitting a duct to the inlet. In fact, the usable regions of some of the wind tunnels at NASA Ames are located on the suction side. This includes the 80x120 foot tunnel...

    What mathematics software should engineering students use?

    The OP is an instructor asking what SW he should require his students to use.

    What mathematics software should engineering students use?

    I work for a large aerospace company and Matlab is almost universally used. Skill in Matlab is a requirement on most engineering job postings here. For reasons of support and security, you won’t find freeware used in industry. The company has a few Mathematica licenses, but I know of only one...

    NASA Currently trying to build a rocket to launch into space

    I suggest that you use capitalization and punctuation in future posts. It’s pretty hard to parse your thoughts without them.

    Graduate Project Progress Report and possible Radio Astronomy Technique?

    There's no R in the formula for power, only for the voltage generated by a resistance. A resistor delivers a power spectral density S=kT W/Hz to a matched load.
