Roger Swanson
Most Minnesotans have never heard of Roger Swanson. But among voyagers around the globe, he's known as the man who circled the world not once -- but three times -- on a 57-foot sailboat whose home port is listed as "Dunnell, MN."
His travels carried him from the tip of South Africa to the Arctic, winning international honors along the way. He also happened to launch a half-dozen manufacturing businesses in rural Minnesota, overseeing production of everything from snowblowers to farm equipment.
Swanson is being remembered this week as an extraordinary adventurer who lived an otherwise ordinary life in southwestern Minnesota.
"Roger Swanson was one of the greatest long-distance voyagers of this era or any other era," said Herb McCormick, senior editor of Cruising World magazine. "Few sailors have gone from the Arctic to the Antarctic and everywhere in between. He was one of a kind." He died December 25th 2012. R.I.P. Roger Swanson.

Is God A Mathematician?
Albert Einstein once wondered: "How is it possible that mathematics, a product of human thought that is independent of experience, fits so excellently the objects of physical reality?" Indeed, Newton formulated a mathematical law of gravity which he himself could verify (given the observational results of his day) to an accuracy of no better than four percent. Yet, the law proved to be precise to better than one part in a million! How is that possible? Or take the example of knot theory – the mathematical theory of knots. It evolved as an obscure branch of pure mathematics. Amazingly, this abstract endeavor suddenly found extensive modern applications in topics ranging from the structure of the DNA to "string theory" – the candidate for an ultimate theory of the subatomic world.
And this is not all. The famous logician Bertrand Russell argued that logic and mathematics are really the same thing. "They differ as boy and man", he said, "logic is the youth of mathematics and mathematics is the manhood of logic." So how can we explain these incredible powers of mathematics? How come that stock option pricing and the agitated motion of pollen suspended in water can be described by the same mathematical equation?
At an even more fundamental level, are we merely discovering mathematics, just as astronomers discover previously unknown galaxies? Or, is mathematics simply a human invention? These (and many more) are the questions that Mario Livio is attempting to answer in "Is God A Mathematician?" The book reviews the ideas of great thinkers from Plato and Archimedes to Galileo and Descartes, and on to Russell and Gödel. It offers a lively and original discussion of topics ranging from cosmology to the cognitive sciences, and from mathematics to religion. The focus on the scientific and practical applications of the fascinating insights of great minds will appeal to a wide audience. (read more)

The Watchers
Sarcophagus lid of Pakal the Great
Genesis Chapter 6, verses 1-4
In the Biblical Old Testament, the Book of Ezekiel tells of a flying object seen as a fiery whirlwind which when descended to the ground gave the appearance of being made of metal. It is described among other things as a wheel within a wheel containing four occupants, living creatures, whose likeness was that of man. The passage goes on to say that wherever the wheels went the creatures went, and when the living creatures were lifted up the wheels were lifted up. (read more) (see more)

Google Earth
For the second time this month, Google is causing an immense amount of speculation.
Google has this time surprised its users with this crop circles logo.
Today’s logo shows a flying saucer above a series of crop circles that spell Google. Well, almost — the L has been abducted. That's similar to the last Google flying saucer logo from ten days ago, where an O was taken.
If you look at today’s logo’s file name, it’s “goog_e.gif” The URL of the logo is “http://www.google.com/logos/goog_e.gif” (there is a missing L). The last logo was go_gle.gif – reflecting the missing O. So that’s O and now L. What next?

Ice Blink
Dave and Jaja spent seven years sailing around the world (1988-1995) aboard their 25-foot Cal 25 DIRECTION. Dave purchased the boat in 1985, gutted her to a bare hull, and then went to work beefing up the structure. He glassed in stringers, added keel floors and extra bulkheads, and then re-designed and re-built the interior. "I built a new rudder, re-stayed the mast, built a smaller cockpit, and then christened her with a bottle of warm Bud in an effort to get the mood right for the intended circumnavigation" is the way Dave puts it.
Dave was 22 when he started this project, and 24 when he finished. He met Jaja shortly after starting his cruise in St. John, USVI, and they finally got together in the UK (after a solo Transatlantic) in the fall of 1988. They were both 25 when they left England on their circumnavigation.
From England they headed West to the Caribbean, via the Cape Verde Islands. They were married in Barbados, then transited the Panama Canal, visited the Galapagos; and did the usual trip through the South Pacific, spending several seasons in Australia, New Zealand, and the nearby cruising paradise to the north. A trip through the Torres Straits, Indonesia, and then across the Indian Ocean had them rounding South Africa before arriving back in the Caribbean and then the States in 1995. Along the way they had two children (Chris and Holly). A third (Teiga) was born aboard DIRECTION at the end of the voyage.
The Martin family set sail again in 1997 on their 33-footer DRIVER, and have spent time in the Bahamas, Bermuda, Iceland, the Faroes, Northern Scotland, Norway, Greenland, and Newfoundland. They are currently settling down for the winter in Maine.
Percy Lavon Julian
Percy Lavon Julian (April 11, 1899 – April 19, 1975) was an African American research chemist and a pioneer in the chemical synthesis of medicinal drugs from plants.
He was the first to synthesize the natural product physostigmine; and was a pioneer in the industrial large-scale chemical synthesis of human hormones, steroids, progesterone, and testosterone, from plant sterols such as stigmasterol and sitosterol.
His work would lay the foundation for the steroid drug industry's production of cortisone, other corticosteroids, and birth control pills. He later started his own company to synthesize steroid intermediates from the Mexican wild yam.
During his lifetime he received more than 130 chemical patents. Julian was one of the first African Americans to receive a doctorate in chemistry. He was the first African-American chemist inducted into the National Academy of Sciences, and the second African-American scientist inducted from any field.

The Mad Scientist
After his demonstration of wireless communication (radio) in 1894 and after being the victor in the "War of Currents", he was widely respected as one of the greatest electrical engineers who worked in America. Much of his early work pioneered modern electrical engineering and many of his discoveries were of groundbreaking importance. During this period, in the United States, Tesla's fame rivaled that of any other inventor or scientist in history or popular culture, but due to his eccentric personality and his seemingly unbelievable and sometimes bizarre claims about possible scientific and technological developments, Tesla was ultimately ostracized and regarded as a mad scientist. Never having put much focus on his finances, Tesla died impoverished at the age of 86.
The SI unit measuring magnetic flux density or magnetic induction (commonly known as the magnetic field "B"), the tesla, was named in his honor (at the Conférence Générale des Poids et Mesures, Paris, 1960), as well as the Tesla effect of wireless energy transfer to wirelessly power electronic devices which Tesla demonstrated on a low scale (lightbulbs) as early as 1893 and aspired to use for the intercontinental transmission of industrial energy levels in his unfinished Wardenclyffe Tower project.
Aside from his work on electromagnetism and electromechanical engineering, Tesla has contributed in varying degrees to the establishment of robotics, remote control, radar and computer science, and to the expansion of ballistics, nuclear physics, and theoretical physics. In 1943, the Supreme Court of the United States credited him as being the inventor of the radio.
