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?

Green Marketing Case Study: Is it really good for you?

Earth Shoes.  “They are good for your posture and good for the earth”.  How convenient is that? Finally some inventor did the right thing, designed a prosaic object such that both entities that came in contact with it benefited enormously [environmentalism]. And at that time there were no forums, no social media, no websites, no internet to “rise up and reveal the lie”.

On April 1, 1970, a new shoe shop opened its doors for business on East 17th Street in Manhattan.  The owners, Raymond and Eleanor Jacobs, soon began to see throngs of hippies flocking by on their way to Union Square to celebrate the first ever Earth Day. In a flash of brilliance, the Jacobses wrote a sign advertising “Earth Shoes” and stuck it in the storefront window.  What used to be plain footwear suddenly became a generational phenomenon; for the better part of the next decade, so-called Earth Shoes were a staple of the American environmentalist’s wardrobe.

The Earth Shoe phenomenon was not just a right-place, right-time aligning of the stars.  It was the first—and perhaps the most successful—case of green-stamping.  Now a well-established practiced, green-stamping involves marketing a product for its environmental benefits.  Seems simple, yes?  The problem lies in the discernment between true sustainability and fakery.  The case study of the Earth Shoe can help shine a light on our own susceptibility to false green-stamping, and let us see clearly the consequences of being duped.

The manufacturing of Earth Shoes, as you can gather, had no connection whatsoever to the environmental ideals promoted by Earth Day.  However, the podiatric craze was filtered through the underlying fabric of a broader social movement, and so it was accepted without much fuss.  It survived for so long because of its unquestioned linguistic connection to early environmentalism (perpetuation by cultural contact high, if you will).

Big Data Conversion Chart & Functional Relevance

A Petabyte is a lot of data, not a generic bite from your pets























My favorite quotes from this post are:

“Data has no inherent value. To be useful, data must flow to agents who will ultimately process, analyze, and synthesize it to produce information that drives decisions. The recent conversation in DoD has focused on what is referred to as the “big data problem,” that is, since we don’t know what’s important in the data being collected, everything must be saved. But this is much harder than it sounds.”

“Data is not important. It’s the information that can be gleaned from the data that matters. The old data paradigm emphasizes precision: save only what you consider to be relevant at the time the data is collected. This approach works only so long as you are dealing with a more or less static context where “relevance” can be readily established.”

Relevance is not an attribute. It’s a relationship, or a complex mapping that has sources, targets, and attribute values on the link. Consider this abstract function:

Relevance = F(source, content, context; me, my role, my situation, my company; the environment and set of competitors and space of potential actions).

Because of these considerations, you can see why relevance is elusive and non-comparable across markets, uses, and situations. THerefore aggregate sums and statistics on relevance are even more problematic.


Crowdsourcing and co-creation

This is nice graphic that explains some relationship across co-creation and crowdsourcing. Interestingly, the social media notion of UGC (user generated content) could be labeled “crowd generated content” and find its way into this umbrella. Co-creation is a great way to develop mutually beneficial relationships between brands and consumers. Engaging in consumer co-creation establishes an ecosystem that encourages interaction. Through these interactions, businesses are able to gain valuable insights, of which can be applied to various aspects of the business- be it for product development, marketing or communication strategies (Source:

How to organize books by size and color for aesthetic effects

Interestingly, by duality you can prove that the better and more “organized” your books look to the eye; the more impossible they will be to find. At least for other people. The fact that people remember their own books by color of exterior may actually help you find a color coded bookshelf arrangement.
