About Me

My Photo

I previously worked on Virtual Reality and other hardware at Valve.  I currently work at Google[x].

Prior to starting at Valve, I built computer peripherals such as keyboards, mice, and joysticks that were designed to be used inside MRI machines.  My company, Mag Design and Engineering, sold these devices directly to researchers at academic institutions who used them to publish scientific papers in peer-reviewed journals.

After work, I spend time on many different types of projects that usually involve circuit design, machining, material selection, and general fabrication/hacking.  My favorite place to be is my home workshop.

Mathematical integration without calculus

I show how to convert an area measurement problem into a mass measurement problem that is easier to solve.  In general, this idea of converting measurement problems into different spaces is very powerful, and may prove useful in the future.


  1. That was pretty cool,I've never been much of a math guy but that seemed quite straight forward.Thanks for the quick lesson.

  2. Might something like a hole punch produce more consistent sized pieces for figuring out the variation of paper mass per area? (using your new scale)

  3. This is assuming very even density of the paper though.

  4. This is how chromatography integration was done 50 years ago. I can send you papers if you are interested
