Space Birthday Facebook App

We’ve just launched our first facebook app, Space Birthday. This app will tell you how many years have passed on other planets since you and your friends were born – that is, how many time Mercury, Venus, Mars, Jupiter and so on have circled the sun.

An Integrator at GraphPower

We’ve just started a new website, GraphPower.com. Our goal is to use that website to provide great calculus software. First up is an online integrator for definite integrals. Just by itself, it should be a great help for calculus students who want to check their work, but we’ll be rolling out a whole bunch of other integrators really soon.
