100 prisoners are imprisoned in solitary cells. Each cell is windowless and soundproof. There's a central living room with one light bulb; the bulb is initially off. No prisoner can see the light bulb from his or her own cell. Each day, the warden picks a prisoner equally at random, and that prisoner visits the central living room; at the end of the day the prisoner is returned to his cell. The central living room is unable to change in anyway other than the state of the light. Also, the light is not viewable to any of the other cells. The cell doors are light proof, as well as being windowless and soundproof. While in the living room, the prisoner can toggle the bulb if he or she wishes. Also, the prisoner has the option of asserting the claim that all 100 prisoners have been to the living room. If this assertion is false (that is, some prisoners still haven't been to the living room), all 100 prisoners will be shot for their stupidity. However, if it is indeed true, all prisoners are set free and inducted into MENSA, since the world can always use more smart people. Thus, the assertion should only be made if the prisoner is 100% certain of its validity.

Don't Google these... That'd be cheating and you'd just be ruining the joy of figuring them out yourself.

1) You are a prisoner in a foreign land. your fate will be determined by a little game. there are two jars, one with 50 white marbles, and one with 50 black marbles. at this point, you are allowed to redistribute the marbles however you wish (e.g. swap a black marble with a white marble, etc.): the only requirement is that after you are done with the redistribution, every marble must be in one of the two jars. afterwards, both jars will be shaken up, and you will be blindfolded and presented with one of the jars at random. then you pick one marble out of the jar given to you. if the marble you pull out is white, you live; if black, you die. how should you redistribute the marbles to maximize the probability that you live; what is this maximum probability (roughly)?

This site has some very interesting and beautiful graphs concerning relationships in the Bible. Check it out.

Here's a pretty cool site that I came across that lets you spell words with images taken from flikr.

This highschool student's video is making a huge impact. Could one of your class projects affect so many people if you took it seriously?

Apple just announced the iPhone . Looks amazing, but it's very expensive too. Not ready until June. Looks like that picture will have to be my iPhone for a while.

Here's the Christmas Gift game

Here's a very interesting video about the differences between a "Christian" and a Christ-follower. Watch the videos at home and think about using technology to communicate important truths about our faith.
