Abstract
We talk about mass and take its meaning for granted.  But what is it actually?  Thinking about Einstein's famous relation E=mc², the mass is a form of energy.  Where does it come from?  We start the discussion with atoms and nuclei, and see how the understanding of mass improves as we go deeper into the heart of the matter.  Much of the mass come from the feverish motion of quarks inside the protons and neutrons; but that is not all.  Quarks and electrons also have mass, that arise when they bump on the "Dark Field" that permeates the universe.  Yet, puzzles remain:  why are the masses so different from one type of particle to another?  What is the dominant mass in the universe we call "Dark Matter"?

The San Francisco Bay Area Mass Spectrometry discussion group was formed in 1980 to provide a regular gathering for people interested in mass spectrometry and allied topics. BAMS currently has a membership of about 280 individual and 20 corporate members, and meets 8-10 times per year for a midweek dinner and lecture.  Meetings attract between 30 and 90 people, and are held at a restaurant or hotel in the bay area convenient for our speaker.  We usually convene at 6:00 pm for cocktails, dinner at 7:00 pm, and lecture at 8:15 pm.

If you have suggestions for a meeting topic, or know of a prominent mass spectrometrist who will be visiting the bay area, please contact our program chair.
