Fun, Puzzles, Travel

Holographic display anyone?

The following are a number of puzzles presented for your entertainment. Feel free to submit any puzzles that you think are interesting, my email address can be found here. If appropriate I will include them here. The main requirement for any puzzles listed here is they should not require any advanced mathematical skills. If you find yourself writing equations for any of the puzzles you are probably approaching it the wrong way. (There are only a couple of exceptions below) The puzzles below are approximately in order of increased difficulty although it is only my own personal impression. To answer your next question, no, answers are not provided to most of the problems. The whole point of a good puzzle is for it to prey on your mind until you solve it. If you are REALLY desperate I will reveal answers if you beg or for a small inducement (eg: beer, chocolates, postcard).

For more information on the counterfeit coin problem see this contribution by Juan Domínguez Montes.

A good way to threaten somebody is to light a stick of dynamite. Then you call the guy and hold the burning fuse up to the phone. "Hear that?" you say. "That's dynamite, baby."

Maybe in order to understand mankind, we have to look at the word itself: "Mankind". Basically, it's made up of two separate words - "mank" and "ind". What do these words mean ? It's a mystery, and that's why so is mankind.

Contrary to what most people say, the most dangerous animal in the world is not the lion or the tiger or even the elephant. It's a shark riding on an elephant's back, just trampling and eating everything they see.
