On the Impossibility of Aggregating Individual Cloud Accretion Rates

The rate of accretion onto the Milky Way (MW) by an individual cloud (or satellite) can be written as dM/dt = M v / R, where M is the cloud mass, v the cloud velocity toward the MW, and R is the distance from the cloud to the MW. Over the time t = R / v a mass M will accrete. This rate can be ev...

String notation for capturing the entire experimental processes of chemistry

A string notation which is inspired by [SMILES](http://pubs.acs.org/doi/abs/10.1021/ci00057a005) notation in chemistry can be devised for capturing entire chemistry experimental and methodological sequences and processes. Laboratory experimental procedures are often described as flowcharts, whic...
