By the numbers, it was just sl > 40 gallons....that's a big tank, not sure they even offer that anymore. (Their website says the upgrade to 30 gallons is $2255!).
Yeah calculus and quantum mechanics aren't particularly useful in my day-to-day living, but...our most recently adopted cat has been named Schrödinger after the famous Austrian physicist's cat "thought" experiment. I do remember hearing about him and the Heisenberg uncertainty principle, tho' I was never certain i really understood. Gotta "B" in that class and was ecstatic. In case you just can't stand it and are bored...
