Modern Physics Series Volume 7, a detailed explanatory book on the physics of light emission. - Title: Physics of Light Emission - Series: Modern Physics for Modern People 7 - Author: Hiroshi Kobayashi - Publisher: Asakura Publishing I purchased this used one year ago. I haven't used it much, and it's in good condition with no writing. Since I bought it used, I've marked it as having some minor scratches, but there are no major stains, and I think it's in good condition for normal use. If you have any questions about the details, please feel free to ask, and I will do my best to answer them.
