I had the privilege of hearing Neri Oxman speak. I mean this in the best way...I've never felt so inspired AND incredibly inadequate/confused in my life. The work she is doing at MIT is beautiful art, biology, material engineering and cutting edge tech. Seriously, it's mind blowing.
Sometimes the math content is one piece that I find hard to meaningfully incorporate into STEM. Neri's project using silk worms to create a geodesic dome - where the rate and length of silk made had deep meaning - is one of the most brilliant and STEAMy projects I've ever seen. The linked video is a must watch for STEMspiration.
