Back in the saddle after missing a week of Else (sorry about that). The best stories from the past two weeks are below, and you’ll note a bit of TED, which ran last week, as well as a fair amount of Google, which is hard to avoid given the focus of this newsletter: If you’re going to cover “becoming data” it’s best you get used to hearing about Google.Read More
(image) If you took first-year physics in school, you’re familiar with the concepts of potential and kinetic energy. If you skipped Physics, here’s a brief review: Kinetic energy is energy possessed by bodies in motion. Potential energy is energy stored inside a body that has the potential to create motion. It’s sort of kinetic energy’s twin – the two work in concert, defining how pretty much everything moves around in physical space.
I like to think of potential energy as a force that’s waiting to become kinetic. For example, if you climb up a slide, you have expressed kinetic energy to overcome the force of gravity and bring your “mass” (your body) to the top. Once you sit at the top of that slide, you are full of the potential energy created by your climb – which you may once again express as kinetic energy on your way back down. Gravity provides what is known as the field, or system, which drives all this energy transfer.Read More
