I heard once π²=10 is fairly accurate approx and thus g=π²=10 in astrophysics where people thinks in order of magnitude, not value.

But my engineering ass is telling assumptions with larger than 50% difference from actual value may cause issues on order of magnitude if the value is used multiple times and isnt it better be like 5=1/2×10?

gut microbiome’s link to gut-brain axis and depreasion so partial points earned? laxatives usually have adverse effect on gut microbiome tho
