Why We Need STEM

Ignite Chicago is an evening of 5-minute talks presented by speakers who want to inspire others. Each speaker is allowed twenty slides, and the slides advance automatically every fifteen seconds. The Ignite organizers asked me to present Why We Need STEM at 1871. I’ll post the video when it becomes available. For now, check out the slides…

Thank you Ignite Chicago organizers (Pete Aiello and Claire Lew) for the invitation and for hosting a great event.

Petascale Tools Workshop 2013

The Petascale Tools Workshop is for computer scientists who create tools that enable apps to run efficiently on the world’s fastest supercomputers. Supercomputer performance is measured in petaflops: 10¹⁵ floating point operations per second. That’s blazing speed, thousands of times faster than the fastest MacBook Pro.

Pat Metheny: Be the Worst

Pat Metheny encourages musicians to “be the worst” in whatever band they choose to join. Of course, he does not mean to play poorly.

Rather, he encourages us to surround ourselves with the best musicians we can find so that we can learn from them. The concept is explored further in the book Apprenticeship Patterns by Dave Hoover and Ade Oshineye.

Successful Companies Are Built Around Communities

Seth Godin is on a mission. Technology enables us to form communities that stretch beyond traditional boundaries like age and social status. Godin is convinced that revolutions within and between communities will yield huge opportunities for those who have the courage to take action. Don’t waste the revolution!

I had the opportunity to hear Godin speak at a Chicago area event some time ago. This post was inspired by the presentation.
