February 2010 Puzzle Solution
There's some multiplication going on here, and the ordinal numbers imply a series. The prime numbers are the "building blocks" of the natural numbers when it comes to multiplication. Take the 22nd prime number, then the 11th, then the 1st times the 1st times the 9th, etc., to get:

79 31 92 6 29 20 47 92 89

Now we need to look at these through the lens of another science. All of these numbers fall within the range of atomic numbers in the periodic table, which is another set of "building blocks". Convert the numbers to elemental symbols:

Au Ga U C Cu Ca Ag U Ac

These symbols all consist of the same four letters: A, C, G, and U. These are the abbreviations for the four RNA bases used in the genetic code, so nucleotides are are final building blocks and biology is our final science. Read these letters in groups of three:

AUG AUC CUC AAG UAC

and take the one-letter symbols for the amino acids they code for to get the answer, MILKY. We stop just short of venturing into another science, astronomy!
