2. The Drake Equation: (a) What, exactly, does the Drake Equation estimate? (b) If you are like Frank Drake or Carl Sagan, you are an optimist who believes that the development of life, intelligence, and technological civilizations are not "vanishingly small", but are typical. That is, that what happened on earth is not rare. Explain them why Drake and Sagan would say that "N=L" is a good approximation to the Drake Equation.

SHOW ALL WORK AND IF THERE ARE ANY VARIABLES USED, EXPLAIN HOW YOU GOT THEM. When the air temperature is below 0 Celsius, the water of a lake freezes to form an ice sheet. The time required to freeze the ice sheet is proportional to the thickness squared if the heat of fusion of the water freezing on the underside of the sheet is conducted through the sheet. Assuming the upper surface of the sheet is at -10 Celsius and...
