spectrograph
Your overall goal is to create a spectrum that is as bright and spread-out as possible so that the locations of hydrogen's spectral lines can be measured The basic idea is shown in the diagram at the bottom of this page. Light shines out from the hydrogen gas tube in all directions. Some of this light is "caught" by a lens called the collimator, which, if placed correctly, collimates light. Collimated light means light rays that are all parallel....

PHILOSOPHY: 1. What is the mind-body problem? a.) Why does my body not do what my mind tells it to? b.) How does the mind relate to the body? c.) How can there be thoughts and no souls? d.) How can it be 'mind over matter' in certain contexts? The mind-body problem is a very, very, old puzzle in philosophy. It is trying to explain how our 'what-it's-likenesses' relate to our bodily states. It's trying to explain how our thoughts,...
