Literalist: The volume of the container is ~50% water.
Engineer: The glass is twice as big as it needs to be.
Bad Engineer: The glass is twice as big as it needs to be.
Good Engineer: The glass is 66% full with a 25% safety margin.
This glass has a safety factor of 2
Re: good engineer: this is the thing that frustrates me amount marketing/labeling for travel mugs or cookware; the listed capacity is the absolute brim capacity not the practical capacity. Want to put 16 oz in a 16 oz mug you’re gonna have to sip 3 ounces out first in order to put the lid on. Want to serve 2 qt soup? Gotta use the 3 qt pot.
I thought the half full, half empty thing. Was about the flow of water. If you’re emptying the glass, at some point the glass will be half empty. If you fill the glass, at one point the glass will be half full.
My lab is pretty easy to guess, it’s either 18 MΩ water, 100% EtOH, or 16M HNO3. 66% chance it’s not acutely dangerous, not bad for a lab!
People who call themselves realist tend to be pessimists.
