He's dedicated to tearing apart the simple lies-to-children that most of us picked up in grade school, junior high, and high school — oversimplifications of things like tongue rolling, dimples, and eye color that make it easier for kids to understand genetics, but end up leaving adults with a skewed understanding of how genetics actually work.

Wireless headphones aren’t a mind-bending thing anymore now that Apple made them the standard thing-to-be-outraged-over-in-the-new-iPhone fare, thereby killing the cool factor. But let’s be reasonable here. Wires really are a pain when you’re running, trying to get off the bus, or even just standing up from your desk. Wireless headphones make sense, they just don’t […]
Python is such a commonly used general-purpose programming language and features such (comparatively) simple syntax, that most veteran programmers consider it an excellent foundation for aspiring programmers. The Python 3 Bootcamp Bundle packs over 30 hours of training into nine courses to build that foundation for you.If you’ve never had any introduction to code at […]
