Each letter has an associated numerical value attached to it, and the total of all the letters equals the physicist‘s total value. For example, if the letters G, L, A, S, E, and R had the values 12, 7, 9, 14, 21, and 5, respectively, American physicist Glaser would have a numerical value of 68.
Your objective is to figure out what the last physicist--Feynman--should be valued.

A sequence of cubes is presented, each containing a color pattern. Below each cube are two codes. The first is a Pattern Code indicating the arrangement of the pattern elements. The second is the Transition Code, that somehow relates to the changes in the patterns between adjacent items. Your task is to do the following:
1. Determine the logic behind the Pattern Codes.
2. Determine the logic behind the Transition Codes.
3. Determine the unique pattern that completes the sequence AND matches the given Transition Code.
Your answer should be a Pattern Code for the final item in the sequence.
Next item Transition Code: 001100-0
Next item Pattern Code: ? (Submit your answer below.)

A box contains two coins. One coin is heads on both sides and the other is heads on one side and tails on the other. One coin is selected from the box at random and the face of one side is observed. If the face is heads what is the probability that the other side is heads?

Consider two breeding strategies of the fictional Furble. Dominator Furbles can fight for a breeding territory, and if they win, will be able to rear 10 offspring. An alternative is to share territory with another Furble which will allow each to rear 5 offspring. Sharers who attempt to share with dominators will be forced out of the territory, although they will be able to find a new territory. Assume sharers become extra cautious after encountering a dominator and so will always find another territory to share the next time around, but due to lost time will only be able to produce 3 offspring. Dominators are always able to force sharers out of the territory and rear 10 young. Dominators who meet dominators will win 50% of the time. When they lose, they are not able to reproduce that season due to sustained injuries. Individual Furbles cannot switch strategies.
With a total population of 2000 dominator and sharer Furbles, how many would you expect to be dominators?
