A map of the sexual networks at a midwestern high school, with each dot representing a student (pink for female, blue for male), illustrates how a student in a relationship with one classmate may unknowingly be linked to hundreds of others. Numbers by a figure indicate how many times that pattern was observed. For example, [...]

Although it would be impossible to do this on earth, you actually could do this on the moon. The moon has a cold core and it also doesn’t have any oceans or groundwater to mess things up. In addition, the moon has no atmosphere, so the tunnel would have a nice vacuum in it that [...]

The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around.

This tiny, near-microscopic water flea has more genes than you. In fact, this freshwater zooplankton is the first crustacean to have its genome sequenced, and its 31,000 genes crowns it the animal with the most genes so far. For those keeping count at home, the average human has about 20,000 to 25,000 genes.

Almost 100 years ago, Frank Morley proved a curious theorem from elementary geometry that unbelievably remained unknown until 1899. With time, the theorem became known in mathematical folklore as Morley’s Miracle (Morley’s Trisector Theorem is a more mundane term.) The theorem states that The three points of intersection of the adjacent trisectors of the angles [...]

Linear programming is often a favorite topic for both professors and students. The ability to introduce LP using a graphical approach, the relative ease of the solution method, the widespread availability of LP software packages, and the wide range of applications make LP accessible even to students with relatively weak mathematical backgrounds. Additionally, LP provides [...]

In a group of at least 23 randomly chosen people, there is more than 50% probability that some pair of them will have the same birthday. Such a result is counter-intuitive to many. In probability theory, thi is known as the birthday problem, or birthday paradox. Here is how we calculate this. Solving the Birthday [...]
