    If a black object warms faster during the day, does it cool faster at night?

    Thanks!

    If a black object warms faster during the day, does it cool faster at night?

    lol so this is related to black-body radiation? Does this actually translate to real-world examples, say I have a car with black upholstery that gets hot fast during the day, will it cool down faster at night than a car with white upholstery? Or is it more complicated than that?

    Graduate What is a probability amplitude?

    Ah I think I have my terminology wrong. I'm watching the Douglas Robb Memorial Lectures and as I understand it calculation of quantum probabilities uses vector addition and multiplication where calculating classical probabilities would use real addition and multiplication. This seemed very...

    Graduate What is a probability amplitude?

    Thank you! Yes, I read the wikipedia article but could not understand it. What is an amplitude then? Why does squaring it yield a probability? Why is it added or multiplied like a probability in calculating the actual probability of combined events? In particular, I do not understand this...

    Graduate What is a probability amplitude?

    I have no idea what it means for a probability to be an amplitude. Can someone give me some kind of intuitive explanation of this concept?
