President Bush set an agressive space exploration agenda for the country. Included is a lunar settlement initiative.
Research on lunar settlements is not new -. Civil, Mechanical, Chemical, and Environmental research intensified in the 90's.

In the face of this, a human question. Is it wrong to deny the human pleasure of drinking, in a setting already devoid of most familiar experiences, and faces, and pleasures?

Can the gravitational pull of the sun be measured on Earth's surface? i.e. Could a person jump higher (theoretically) in the day, because some of Earth's gravitational pull is offset by the gravitational pull of the sun? Also, if the earth's gravitational pull against the moon is enough to create a bulge in the earth (tides) then why doesn't it have more effect on people on Earth's surface?

Two large tanks, each holding 100 L of brine. The tanks are interconnected by pipes
that allows fluid to flow between the tanks. The liquid flows from tank A to tank B
at a rate of 3 L/min, and from tank B to tank A at a rate of 1 L/min. A brine
solution flows into tank A at a rate of 6 L/min with concentration of 0.3 kg/L.
Solution leaves tank A at a rate of 4 L/min and from tank B at 2 L/min. If there was
initially 10 kg of salt in tank A and 20 kg of salt in tank B, find an equation for the
amount of salt in both tanks at time t.
