Episode notes
Mascot-Color Baby Name Game
- Listeners submitted playful 'mascot color' name combos and the hosts read many creative examples on air.
- John and Hank repeatedly laughed at favorites like 'Cock Blarnet' and 'Crimson Ann White'.
Pick Self-Pollinators For Simplicity
- Choose self-pollinating plants if you want simple reproduction without needing other plants or pollinators.
- John prefers being a pea plant because it can self-pollinate and avoid involving bees or other helpers.
Percentages Can Mislead Absolute Amounts
- Mars has ~95% CO2 by composition but far less total CO2 than Earth's atmosphere because Mars' atmosphere is much thinner.
- Plants alone couldn't breathe life into Mars without massively increasing atmospheric density and engineering plant tolerance.
