An explorer goes on an expedition in the jungle. He sets up a camp in the middle of the jungle. The next morning he sees something with a head and a tail, but he is not afraid. What did he see?
Can you name the athletes by the picture?
There is a straight highway. Four different villages lie on that highway. The distance between them is different. The third village is 60km away from the first village; the fourth is 40 km away from the second; the third is 10 km near to the fourth that it is to the second. Can you calculate the distance between the fourth and the first village?

Dewar shows objects cooled with liquid air

In 1895, James Dewar demonstrated the intimate connection between phosphorescence and photographic action of the electric light on bodies cooled to the temperature of boiling liquid air. Presented at the Royal Institution, these experiments were reported as “very remarkable.”

Math Teacher

The night before one exam, two students tied one on, (well, actually, tied two on, one each), and managed to sleep through the final. They realized they were in serious trouble, so they agreed to tell the professor that they had a flat tire on the way to the exam.
``No problem." said the Professor, ``Come by my office at 5 P.M. and I'll give you the exam then."
Feeling pretty clever, the students spent the intervening time getting information on the exam from students who had already taken it, and making sure they knew how to do the problems. Coming to the professor's office that evening, they were told, ``Leave your books in my office, and I'll put you in two separate rooms for the exam." They were both ecstatic to see that the Professor had given them the exact same exam taken by the class that morning. However, there was an additional page tacked on the end, upon which was written, "For 50% of the grade, which tire was flat?"
