• A whimsical arXiv paper (1807.10553) was shared that rigorously models the physical consequences of the Earth being instantaneously replaced by an equal volume of uncompressed blueberries, treating the scenario as a useful analogue for a small ocean-world exoplanet.

• Discussion highlighted the real-world existence of preparative mass selectors—mini-school-bus-sized mass spectrometers used in semiconductor ion-implantation that deposit selected isotopes onto a target instead of scanning them for detection.

• Historical context was provided by linking these modern devices to the Manhattan Project’s Calutrons, which similarly separated isotopes at preparative scale.

• Participants debated the fate of NASA’s mechanical counter-pressure space-suit program, speculating that continued development may have been abandoned after the design failed to win the agency’s suit competition.

• One participant declared an intention to leave academia after graduation (end of 2022), stating that neither a master’s nor a PhD path feels suitable for their goals.
