Leonardo Da Vinci Exhibit

There is an exhibit on Leonardo da Vinci at the Metreon. There are numerous reproductions of da Vinci’s work from his drawings. Some are interactive pieces. There are also some unimpressive reproductions of his artwork too. If you’re unfamiliar with his artwork or inventions, it’s a nice introduction to the extensive collection of contributions this genius made to society. I liked the digital representation of Vitruvian Man, that’s the picture with the man embeded in a circle.

The exhibit goes through December 31, 2007.  The cost is $15.50 for students and $19.50 for adults. If you go, let post a comment and let us know what you learned and what liked about the exhibit.

Scatterplots

If you want to know a lot more about the different types of scatterplot correlations, this website has it. It explains that if the points are in a linear relationship, it’s called a perfect positive (or negative) correlation. It also shows some examples of the difference between a strong and weak correlation. The data is assigned a value from 0 (no correlation) to 1 (a perfect correlation).
