At this morning's seminar Craig gave an excellent power point presentation on the physics of photosynthesis and fluoresence. Craig was mostly concerned with the emitted light after PS1 have absorbed light. He studied this process with a smear camera which allows the amplitude and wavelength of a light pulse to be studied over a short period of time. Craig had found that here were four different light emissions with different time constants.

Next we talked with Petra about some possible inorganic crystal growing projects we could do next week which might be suitable for our classrooms. Also , next week, we will work on isolating the GFP protein.
