Variable Co Ordinance Structures

Vegas, of course, is the Mecca of sunk-costs and chasing your losses. All those shiny lights, showgirls, and Cirque Du Soleil’s (I'm pretty sure I saw them open what seems like the 38th Cirque inside a Starbucks though I must admit the new Beatles Cirque show had me at hello) that keep you captive weren't funded by your wins.
As Scott Adams has said, "Probability is omnipotent and omnipresent. It influences every coin at any time in any place, instantly. It cannot be shielded or altered. And probability is not limited to coins and dice and slot machines. Probability is the guiding force of everything in the universe, living or nonliving, near or far, big or small, now or anytime."
CEO Zander peddled onto the stage on a bright yellow bicycle {Las Vegas for the 2007 CES (Consumer Electronics Show). Bill Gates kicked it off Sunday evening, followed Monday morning by Motorola CEO Ed Zander (full disclosure: my firm Lux Capital manages capital for Motorola through our venture capital fund). }. Gimmick aside, he's onto something. Who else rides bikes? Chinese citizens: nearly 500 million of them. What's that got to do with Motorola? A small device connected to the back wheel powers a new Motofone, which has a low-power E-Ink display that can be recharged just by kinetic energy from peddling the bike. Too early to tell if it takes off but it's an example of thinking about the so-called "Fortune at the Bottom of the Pyramid." (That is: the four billion people who are a highly dispersed and fragmented market with low purchasing power parity who in aggregate actually have more purchasing power than France, UK, Italy, Japan and Germany combined).
Now here’s a Vegas riddle. There's a casino in Vegas with 50 slot machines. Each one is standard and has the same payout ratio. In other words, each will payout a certain percentage of the coins put into it and what triggers the payout is the same in all the machines. They all function at the same speed, the same volume and have the same amount of flashing lights. Here’s the rub: one of the machines, no matter where the casino positions it, ends up collecting about 25% more winnings for the casino at the end of every day than any of their other slot machines. Why is this? What's causing this?
The answer is that this slot machine has more "near-misses". It has more sequences that go: bar-bar-banana, bar-bar-lemon, giving the player the illusion that they were oh-so-close and results in heavier play.
Working in the middle 70's last century with variable co ordinances recognize here a lot of ideas "on debate " at that time.

Properties Depend On Cluster Size
Numbers of edge atoms dictate physical and chemical properties of nanoparticles
Mitch Jacoby
What a difference a few atoms can make.
Tiny variations in the numbers of atoms along the edges of molybdenum disulfide nanoparticles can profoundly influence the crystal's atomic-scale structure and coordination, electronic properties, and other characteristics, researchers in Denmark have shown. The findings may lead to improvements in MoS2-based desulfurization catalysts for fuel cleanup and to advanced lubricants and other applications.
With legislation in the U.S., Europe, Japan, and elsewhere calling for ever lower levels of sulfur in transportation fuels, scientists are redoubling their efforts to sort out the reaction mechanism that drives hydrodesulfurization, a process in which sulfur is stripped from hydrocarbons and converted to volatile hydrogen sulfide in the presence of MoS2-based catalysts.
Previous studies indicate that the edges of thin, supported MoS2 nanoclusters, which are often equilateral-triangular in shape, contain highly active catalytic sites, which are especially active when the clusters are very small. The high activity is often attributed to the unique coordination of edge atoms and the presence of reactive edge defect sites. But those features have not been explored in atomic-resolution detail until now.
On the basis of scanning tunneling microscopy (STM) measurements, Aarhus University physics professors Jeppe V. Lauritsen and Flemming Besenbacher and their coworkers at Aarhus and at catalyst manufacturer Haldor Topsøe have shown that nanoclusters with six or more molybdenum atoms along an edge coordinate sulfur differently than do nanoclusters containing fewer than six edge molybdenum atoms. Specifically, the team finds that along the edges of the larger crystallites, each Mo atom bonds with two outermost S atoms (S "dimers"), which tend to line up with neighboring atoms to form pairs of S "dimers." In contrast, the edges of smaller clusters exhibit Mo-S=Mo bridge structures (Nat. Nanotechnol. 2007, 2, 21). The team also reports that the smaller clusters are less stable (more reactive) and more prone to vacancy defects than the larger clusters. And they note size-dependent differences in the clusters' STM signatures, which indicate the clusters' differing electronic structures.
In an accompanying commentary, Gotthard Seifert, of the Technical University of Dresden, and Sibylle Gemming, of the Rosendorf Research Center, both in Germany, note that the difference between the large and small nanoclusters "turns out to be the key to understanding the structural, electronic, and catalytic properties of these particles."

The last key principle is this: evolution. Organisms, technologies, business models, social structures all evolve. And this is one of the most important pieces of the puzzle. There are a few key aspects in the process of evolutions whether in life, inventions or ventures.
First is "variation". In life: it’s via random mutation. In technology: it’s via accidental discovery, intentional invention, trial and error and combination of already existing technologies.
The second aspect: once there are a variety of things, it’s clear that some are better than others.
The third feature is that there’s some process or algorithm of "selection". And of course the fore mentioned 'better' depends on what environment or landscape the thing is performing or competing in. The fancy name for this is "fitness landscape". Think of climbing a mountain: you try to scale a local peak. When you get to the top, you might see a new peak which could even require you to descend, move to the new base and then climb again. Tiger Woods did this years ago to perfect his swing so did IBM. And so it is with technology adoption, startup companies and even incumbent companies that can adapt and reinvent themselves.
The last key feature is amplification. Good biological designs or good technologies or businesses benefit from positive feedback effects and get dialed up. They get amplified, attract capital, get more adopted and spread through the proverbial (or literal) gene pool. Conversely, bad ones get dialed down. They get negative feedback, lose prominence, suffer from decreased population size or even extinction.
There’s one key part of this framework that I’ve found frustrating. Feynman famously said that for a successful technology, reality must take precedence over public relations, for nature cannot be fooled. But I’ve realized to the unfortunate happenstance of investors: that people can be fooled namely by other people.
APPLICATIONS: TRANSISTORS
Researchers at the University of Wisconsin, Madison, have made ultrathin silicon transistors that operate more than 50 times faster than previous flexible-silicon devices. The advance could help make possible flexible high-end electronics that would be useful in a variety of applications, from computers to communication. Jack Ma, professor of electrical and computer engineering and lead researcher on the project, is interested in using flexible electronics to redesign large-scale antennas that could be molded in the shape of, say, an airplane. For instance, radar antennas could be made to cover a large area on an airplane, he says, increasing sensitivity and area of coverage.

The End of Alchemy

or The End of Damascus Sword.



THE INTERNAL ALCHEMY OF THE TAO






This chart was never copied for several hundred years. There was only the
original. It was never passed down to the rest of the world because it is so
profound and mysterious that an ordinary person would have no way to understand
it. It was rediscovered in the library at High Pine Tree Mountain in China
suspended from the wall. It was carefully drawn and the printing was clear, so
it was eventually reprinted at that time. When I first discovered this, I
decided to reprint it with a complete explanation using the Universal Tao
practices. By practicing the Universal Tao formulas you can start to comprehend
the detailed illustrations of this mural connecting with our body and the
universe. The Tao adept saw the human body as a microcosm of the natural world.
Its anatomy was a landscape with mountains, rivers, streams, lakes, pools,
forests, fires, stars etc. a natural harmonious landscape. It show a torso and
head with few easily identifiable structures. - Mantak Chia

The Arabs appeared in history in the seventh century. Alchemy had by then gone through a long path. The first contacts took place in Egypt, in Alexandria, where the traditions went back several centuries before Christianity. Muslim alchemy was derived from the Greek. The frequency with which Greek authors are quoted, the numerous theories that are common to both Greek and Arabic alchemy, and the large number of Arab technical terms clearly taken over from Hellenic treatises (e.g. hayuli, atisyus, athalia, iksir, qambar,S) prove beyond doubt the affiliation of Muslim and Greek alchemy. The transmission was made partly through direct contact in Egypt, partly through the medium of Syrian Christian translators, and partly by way of Persia. There are unmistakable traces of Persian influence, manifested distinctly by linguistic affinities in technical names and usage and in names of minerals. These traces are sufficiently well marked to render it probable that Persia was, indeed, one of the main channels through which alchemy came to Islam; and it is not without interest to note that many of the principal Muslim alchemists were Persians.It has already been observed that Chinese alchemy has so much in common with Greek and Arabic alchemy as to afford support to the hypothesis that all three had a common origin; and there is some reason to believe that the Chinese practiced a kind of alchemy long before the days of Islam. The remote origins of Arabic alchemy are therefore still to some extent uncertain, but there is very little to recommend the suggestion that the Arabs received any direct introduction to alchemy from the Chinese. Whatever may be the cause of the similarity between Chinese, Greek and Muslim alchemical ideas.

Paracelsus, Philippus Theophrastus Bombastus von Hohenheim
(1493-1541)
Paracelsus was a physician and Alchimist, who

introduced the treatment of diseases with chemical means to the Renaissance. The
progress of the practical medicine at the beginning 16. Century is to be owed to
a large extent to it, like also the beginning to the modern medicine and
chemistry.
Time life did not omit it an opportunity, in order to make
academic authorities ridiculous. When it accepted a teaching profession in
Basel, it provoked the authorities, by burning the works of the well-known Greek
physician Galen publicly. It worsened its situation further still by the fact
that it opened its lectures for everyone and held it into German, instead of in
latin.
Like Hippokrates Paracelsus believes in a treatment, those of the
body as a whole one goes out and in the welfare strength of the body. It means,
it developed an effective means against the plague - a pill from paste with
traces of eliminations of the patient. He regarded magic or "mental forces" as
important for the healing process.
While he scoffed the Astrologie, he
looked in the Alchimie for fundamental truths: "magic is a large hidden wisdom
-, he explained understanding a large open foolishness". Its interest to the
Alchimie finally led it to some fundamental realizations in the area of the
chemotherapy.
And so the Damascus Sword reciept was lost. But new words like
swords appear: chemy, chemoterapy.How? " Paracelsus was first, which assumed
lung diseases were caused by mountain workers by inhalation of metallic "steams"
and not by bad spirit."
Alchemy was splited on two: chemistry and
chemotherapy. On the blade remain astrology!And spiritual problems passed to
religion.
