Will it include the physics of beer drinking? ...coz that part was missing from your Powerpoint presentation.
That's another class. The physics of bubble formation in beer is really quite interesting. Have you noticed some (like Guinness) have little gizmos in the bottles to promote proper bubble formation?

Sounds interesting. I would love to come but the damn banks won't increase my overdraft and my credit card companies won't do give me a reasonable limit either. So being a poor student with no money to fly over to the US, would you be able to record(audio or video) the lecture and stick it on a website for me to download?

You can also use the example of the bubbles to discuss velocity saturation of carriers in semiconductors.

Beer I can relate to skydiving. Semiconductor physics is a bit of a stretch.

Most beer contains only dissolved carbon dioxide. Guinness adds nitrogen as well.

That's because it needs to stay gaseous to assist in bubble nucleation. If they added CO2 in their gizmo, it would dissolve. N2 is (effectively) insoluble.

Grrr...I thought I was going to be able to make it, but I have some work to do. I'd have to leave here by 2:30, and I just don't see that happening. Booo! It sounds interesting!
