A Whale of a Tale

I know I will never understand the physics behind holograms.  They were patiently, but futilely, explained to me, one-on-one, by Dr. Albert Baez from MIT, who was one of the inventors of the x-ray microscope and the hologram.  In his spare time he fathered folksinger Joan Baez.

Watch this truly incredible hologram of a whale diving in a school gym.  It’s amazing how it’s getting increasingly difficult to tell reality from fiction…

Sleuthing the location of Vermeer's "Little Street" painting

http://www.smithsonianmag.com/smart-news/expert-has-figured-out-real-life-location-vermeers-little-street-painting-180957696/?no-ist
Grijzenhout pinpointed the little street to the stretch in front of present-day No. 40 and 42 Vlamingstraat, Delft.

Grijzenhout consulted a historical document, De legged van het deepen der watered binned de star Delft (The ledger of the dredging of the canals in the town of Delft), which was published in 1667, just a decade after the painting was created. The ledger includes a calculation of how much tax each house owner needed to pay, and records the width of each building and nearby passageways.

Two houses, about 20.6-feet wide with adjacent passageways that measured just under four-feet wide, proved to be a match for the houses and paths in the painting. Those buildings have since been replaced — though the passageways remain —they were there when Vermeer would have painted them. “There was no other place in Delft during that time where this constellation was found.”

Bayes' Theorem shows why bulk surveillance by NSA won't work

http://policestatedaily.com/the-mathematical-paradox-that-destroys-the-argument-for-nsa-surveillance/

For the sake of argument, let us say one out of every million people is a terrorist (an overestimate). Let us also imagine there exists a machine that can determine whether someone is a terrorist with 99.9 percent accuracy.

What are the odds an individual tested is a terrorist? 0.1 percent chance right?

So the 99.9 percent accurate test will give you the wrong answer 99.9 percent of the time. This is what is known as the false positive paradox, and it completely dismantles any possible justification for the NSA’s dragnet surveillance of our phone calls and emails.
