i would like to understand the scientific reasoning
i think that the dimples are widgets. i think it has something to do with surface area of bottom of the glass.

They don’t!
Only a glass with a widget in the bottom does this.

The yeast in the lager interacts with the widget at the bottom of the glass, causing the yeast to interact with air, thus making a chemical reaction similar to carbonation. The widget simply allow more air to interact with the lager and yeast to ferment it and make the carbonated effect, so it looks like more bubbles, but is a natural chemical reaction.

CO2 bubbles are created in carbonated beverages at “nucleation points”. Sometimes nucleation points are just hard water deposits on the inside of the beer glass. If a beer glass is dimpled, then there is a larger probability that there will be nucleation points there.

As an experiment, you can shake some granulated salt in to your beer and watch it explode with bubbles since you supplied all those new nucleation points (salt granules).
