Thread 'Old engineer, new physics student'

Hi there! This is Vmax, an old (relatively, but the profession can definitively accelerate aging) aerospace engineer now returning to physics in my 50s. I can definitively use some help in refreshing long forgotten topics and guidance in tackling new challenging subjects in modern physics. I'm looking forward to engaging in interesting, informative and stimulating conversations with you all. Have a great day!
