Scale, proportion, and quantity belong to one of the cross cutting concepts in the next generation science standards (NGSS). According to Volume 2 of the NGSS, "in engineering, no structure could be conceived much less constructed without the engineer's precise sense of scale." The authors go on to note that scale and proportion are best understood using the scientific practice of working with models.
When scientists and engineers work with these concepts at a molecular scale, new kinds of technologies can be created to advance our understanding of the natural world. One example is DNA ... Read more
I'm currently at the Hi-Tec conference in Scottsdale, Arizona. (If you follow me on Twitter - www.twitter.com/@digitalbio - you may have seen me complaining about the temperature). It's an interesting conference, so I'm going to share some of the things that I'm learning.
Dr. Travis Benanti and Dr. Steve Fonash from Penn State University are presenting an interesting session this morning on nanotechnology.
Luckily, you don't have to know anything about nanotechnology to find ... Read more
