Document Summary

The central issue here is the nature of persons. Materialism: the only things that exist are material (physical) entities and their properties. Dualistic interaction ism: humans consist of material and immaterial (mental, spiritual) components, and these components interact with one another. That"s all. ideas? is interpreted broadly to include sensations, perceptions, thoughts, etc. Parallelism ? there is a mental realm and a physical realm but they don"t interact with each other. Ordinarily, we distinguish between mental and physical events or states of affairs. A mental event (like an auditory sensation) is an awareness, a state of consciousness. Physical things, events, processes, etc. , are located in space. Physical objects, events and processes are publicly observable; but mental ones are not. Mental entities and states of affairs are private. I make inferences form your appearance, behavior, etc. When you look at the same grass you say that you see green. I always agree with everyone else when we discuss colors.

Neutrinos very rarely interact with anything and thus are very hardto detect. About 10^14 neutrinos from the sun pass through yourbody every second, even at midnight (the neutrinos easily gothrough the earth), but this is of no concern since only one a dayinteracts with any quark or lepton in your body. In fact, aneutrino would have to pass through several thousand light years ofsolid lead before it would have a 50-50 chance of being absorbed.Given the information in C1.5, see if you can explain why neutrinosso rarely interact with normal matter.\

C1.5 describes interactions (Gravitational, Electromagnetic, Weaknuclear, and strong nuclear), and also includes a table aboutLeptons and Quarks.

I was thinking the answer was that Neutrinos don't react withmatter very frequently because they have little to no mass, and nocharge - thus they can only participate in weak nuclearinteractions or gravitational interactions which are extremelyweak.

Is this the correct line of thinking?

Calculate the wavelengths of the fine structure components of theLyman-alpha line in singly ionised helium according toSchrodinger/Dirac theory and spin-orbit interaction.
Make a rough estimate of the Doppler broadening of these lines.What conclusions do you draw from this result?
