Okay, it seems that I do not have enough background information to attend such a calcium isotope reading group. Within the

first few minutes, I got lost in the discussion, and could only cling on to a few general concepts. I feel that if I had

a stronger background in isotope geochemistry, I would have been able to contribute more to the discussion. Oh also,

these discussions were pretty informal. They usually had around 3-5 graduate students along with Jon, the professor/PI.

All I could do was listen. I don't think I'll come to these sessions anymore, despite the fact that they always have

a lot of new information. It's just too much for me to handle.
