A recent report addresses what appears to be a long-observed phenomenon in some circles: That bubbles in stout often sink, rather than rise. No, this is not an effect enhanced by increased consumption of the imbibable under discussion; rather, it is a very real phenomenon, seen even by those who are not inclined to see what is not there. It …
Perceived Powerlessness?
The news in several places that the recently released movie, The Avengers broke the $1 billion mark for ticket sales (see here, for example) left me wondering, Why? What is it about this movie that has knocked earlier blockbusters (such as the Harry Potter canon) off their pedestals? I mean, I love a good movie, and may even set things …
An Intolerable Situation
Yesterday the House of Representatives voted overwhelmingly (248-168) to pass the Cyber Intelligence Sharing and Protection Act of 2011 (H.R. 3523), known as CISPA. I don’t usually express opinions per se here, but this time I will: I find this intolerable I acknowledge that things are getting very dicey in the cyber world, and that there is increasing need for …
Protective Coloration
A recent report from the California Academy of Sciences caught my eye, as it seemed to have implications for organizational dynamics. Summarized here, with a video of the interaction here, the report describes how a fish has developed the capability of imitating the look of an octopus that imitates the look of potentially dangerous fish, thereby allowing the octopus and …
What Would You Do If You Could Not Fail?
I came across this question recently via two different communications channels (Wired magazine and a YouTube video), both referring to the same person. That person is Regina Dugan, who—until March 2012—was director of the Defense Advanced Projects Research Agency, or DARPA. She left DARPA to move to Google, and faced lots of criticism for the way she allocated work to …
Interaction Modes
Flatter me, and I may not believe you. Criticize me, and I may not like you. Ignore me, and I may not forgive you. Encourage me, and I will not forget you. -William Arthur Ward, college administrator, writer (1921-1994) Questions: How do you interact with others? What do you do to get others to change their behavior? What makes you …
Functional Fixedness
What do a flock of starlings (known as a murmuration) and ferromagnetism have to do with each other? On the surface, probably nothing. Nothing, that is, unless you are a team of scientists with a perspective and approach that goes outside what their nominal area of study seems to call for. A team headed by William Bialek at Princeton University …
It Must Be Magic
A little item has crossed my desk twice in the past week. As is often the case, it came from two different correspondents, a continent apart. How and why such things spread is worthy of another post, but for now, allow me to point you to this: A little thought and some research that confirmed my hypothesis was very satisfying, …
Hydrodynamics and Crowds
I took some time today to try to catch up on readings that have eluded me owing to other, perhaps more pressing matters. An article in the December 2011 issue of Communications of the ACM 54(12) caught my eye, with the engaging title of “Visual Crowd Surveillance through a Hydrodynamics Lens”, by Moore, Ali, Mehran, and Shah (included just for …
A Thought for Today
The world looks with some awe upon a man who appears unconcernedly indifferent to home, money, comfort, rank, or even power and fame. The world feels not without a certain apprehension, that here is someone outside its jurisdiction; someone before whom its allurements may be spread in vain; someone strangely enfranchised, untamed, untrammelled by convention, moving independent of the ordinary …
