Oh Lord, please don’t let me be misunderstood…

Consider the case of Gregor Mendel:

You probably know Mendel as the guy who pioneered the science of genetics… Anybody with a high school diploma has filled out those dominant/recessive trait Punnett squares … … though astute readers are probably wondering why that technique is called a Punnett square if it predicts patterns Mendel discovered.

What you probably didn’t know was that before making his revolutionary discovery, Gregor Mendel flunked out of school and resigned himself to a quiet life as the abbot of a monastery. It had an extensive experimental garden and there Mendel patiently spent the next seven years of his life breeding and cross-breeding peas.

He carefully documented his work and developed what would eventually be known as Mendel’s Laws of Inheritance. Then he wrote it up and got it published in an lesser-known journal, the Journal of the Brno Natural History Society in 1866.

His genius was rewarded by … A quiet life of complete anonymity. Mendel’s work was read by about zero people, even after he took it upon himself to contact the highest minds of his time by personally sending them copies of his theory… Why did they ignore him? Because the greatest minds of his time couldn’t understand him. It wasn’t until 16 years after his death that three independent botanists rediscover Mendel’s work and started the genetics ball rolling.

Read a more colorfully-worded version of Mendel’s story, and the tales of four other scientific pioneers, in “5 Famous Scientists Dismissed as Morons in Their Time.”

As we reconsider the advice we got from the wild-eyed gentleman standing in the DMV line this morning, we might recall that it was on this date in 1900 that Nature reported the development of the first fully-electric musical instrument, the Musical Arc (or Singing Arc) developed by English physicist and engineer William Dudell.

Before Edison “invented” the electric light bulb in the United States, electric street lighting was in wide use throughout Europe; the carbon arc lamp generated light by creating a spark between two carbon nodes. But this method of lighting produced an annoying constant humming noise from the electric arc.  Duddell, who was appointed to solve the problem in London in 1899,  found that by varying the voltage supplied to the lamps he could create controllable audible frequencies from a resonant circuit caused by the rate of pulsation of exposed electrical arcs.  He attached a keyboard to the arc lamps– and created the first electronic instrument that was audible without using the yet-to-be-invented amplifier or loudspeaker.

Duddell– who also invented the moving-coil oscillograph (an early oscillator-type device for the photographic monitoring of audio frequency waveforms), the thermo-ammeter, thermo-galvanometer (an instrument for measuring minute currents and potential differences later used for measuring antenna currents and still used in modified form today), and a magnetic standard (used for the calibration of ballistic galvanometers)–  never patented his discovery.

Two bulletins…

First, from New Scientist:

An electromagnetic “black hole” that sucks in surrounding light has been built for the first time.  The device, which works at microwave frequencies, may soon be extended to trap visible light, leading to an entirely new way of harvesting solar energy to generate electricity.

A theoretical design for a table-top black hole to trap light was proposed in a paper published earlier this year by Evgenii Narimanov and Alexander Kildishev of Purdue University in West Lafayette, Indiana. Their idea was to mimic the properties of a cosmological black hole, whose intense gravity bends the surrounding space-time, causing any nearby matter or radiation to follow the warped space-time and spiral inwards.

Narimanov and Kildishev reasoned that it should be possible to build a device that makes light curve inwards towards its centre in a similar way…  Now Tie Jun Cui and Qiang Cheng at the Southeast University in Nanjing, China, have turned Narimanov and Kildishev’s theory into practice, and built a “black hole” for microwave frequencies…

Then, from Network World:

A 12 million digit prime number, the largest such number ever discovered, has landed a voluntary math research group a $100,000 prize from the Electronic Frontier Foundation (EFF).

The number, known as a Mersenne prime, is the 45th known Mersenne prime, written shorthand as 2 to the power of 43,112,609, minus 1 . A Mersenne number is a positive integer that is one less than a power of two, the group stated.

The computing project called the Great Internet Mersenne Prime Search (GIMPS) made the discovery on a computer at the University of California, Los Angeles (UCLA) Mathematics Department.  Computing manager Edson Smith installed and maintained the GIMPS software at UCLA, and thousands of other volunteers also participated in the computation…

More at Network World.

(Readers may recall that (R)D reported last March on GIMP and the effort to find the next Mersenne Prime– at which point the estimation was that it might stretch to a mere 10 million digits.  Clearly, GIMP’s over-achievement affirms its worthiness of the EFF award.)

As we channel Mr. Wizard, we might run a celebratory riff for Charles Edward Anderson “Chuck” Berry, born on this date in 1926–  Hail, Hail, Rock and Roll!
