H2O (water) has 2 hydrogen atoms and 1 oxygen atom.
so one liter is about 2. something gallons so at 12.8 km/l you would get about 30 mpg which is insane but yeah
Umm...Well...
Heisenberg's Uncertainty Principle says that we can never know both the position and rate of change of a particle at any time. We can only know one or the other. This leads to rather silly jokes that deal with uncertainty, probability, and superposition. So, saying that "Heisenberg may have slept here" is essentially saying that it is uncertain if Heisenberg slept there or not, making for a rather silly, but slightly unfunny physics joke.
