Visual Recall Devices for Electrodynamics formulas

Ingenious use of hand shapes to recall the structure of formulas in Electrodynamics. The kernal of this wisdom is that the hand is one of the few “devices” that must be allowed in any testing situation for students. Yes, I know there is an iPhone app for each formula that plots in 3D, etc. But what if you had solve these equations after a ship wreck?

Astronomy Needs “Forecast Transparency” for Observatories

There is an interesting visualization of forecast transparency and using atmospheric data here. Science is usually my inspiration for both calculating metrics and visualizing them for business. Sometimes though, the business data needs to be more summarized, and less accurate, more simplified, and have some of the statistics removed….

There is an interesting contrast when comparing this to the concept of Business forecast transparency. In business parlance, Forecast is future revenue and future earnings; not future weather. Transparency means that external people (usually analysts) can see how the metric (in this case Forecast) was derived. The formula and source data (or leading indicators). In the case of Astronomy, the transparency refers to the visibility through the atmosphere.
