Absolute Hot temperature


Absolute hot is a concept of temperature that postulates the existence of a highest attainable temperature of matter. The concept has been popularized by the television series Nova.  In this presentation, absolute hot is assumed to be the high end of a temperature scale starting at absolute zero, which is the temperature at which entropy is minimal and classical thermal energy is zero.

Contemporary models of physical cosmology postulate that the highest possible temperature is the Planck temperature, which has the value 7032141678500000000♠1.416785(71)×1032  kelvin.  Above ~1032 K, particle energies become so large that gravitational forces between them would become as strong as other fundamental forces according to current theories. There is no existing scientific theory for the behavior of matter at these energies. A quantum theory of gravity would be required.  The models of the origin of the universe based on the Big Bang theory assume that the universe has passed through this temperature about 10−42 seconds after the Big Bang as a result of enormous entropy expansion.

Another theory of absolute hot is based on the Hagedorn temperature, where the thermal energies of the particles exceed the mass-energy of a hadron particle-antiparticle pair. Instead of temperature rising, at the Hagedorn temperature more and heavier particles are produced by pair production, thus preventing effective further heating, given that only hadrons are produced. However, further heating is possible (with pressure) if the matter undergoes a phase change into a quark-gluon plasma.  For hadrons, the Hagedorn temperature is 2 × 1012 K, which has been reached and exceeded in LHC and RHIC experiments. However, in string theory, a separate Hagedorn temperature can be defined, where strings similarly provide the extra degrees of freedom. However, it is so high (1030 K) that no current or foreseeable experiment can reach it.

Quantum physics formally assumes infinitely positive or negative temperatures in descriptions of spin system undergoing population inversion from the ground state to a higher energy state by excitation with electromagnetic radiation. The temperature function in these systems exhibits a singularity, meaning the temperature tends to positive infinity, before discontinuously switching to negative infinity.  However, this applies only to specific degrees of freedom in the system, while others would have normal temperature dependency. If equipartitioning were possible, such formalisms ignore the fact that the spin system would be destroyed by the decomposition of ordinary matter before infinite temperature could be reached uniformly in the sample.[

The Evolution of Snakes

by Jim Shelton, Yale News, May 19, 2015

The ancestral snakes in the grass actually lived in the forest, according to the most detailed look yet at the iconic reptiles.

A comprehensive analysis by Yale University paleontologists reveals new insights into the origin and early history of snakes. For one thing, they kept late hours; for another, they also kept their hind legs.

“We generated the first comprehensive reconstruction of what the ancestral snake was like,” said Allison Hsiang, lead author the study published online May 19 in the journal BMC Evolutionary Biology. Hsiang is a postdoctoral researcher in Yale’s Department of Geology and Geophysics.

“We infer that the most recent common ancestor of all snakes was a nocturnal, stealth-hunting predator targeting relatively large prey, and most likely would have lived in forested ecosystems in the Southern Hemisphere,” Hsiang said.

Snakes have always captured the imagination of humans. Their long and sinuous body, fearsome reputation, and great diversity — with more than 3,400 living species — make them one of the most recognizable groups of living vertebrate animals. Yet little has been known about how, where, and when modern snakes emerged.

The Yale team analyzed snake genomes, modern snake anatomy, and new information from the fossil record to find answers. In doing so, the researchers generated a family tree for both living and extinct snakes, illuminating major evolutionary patterns that have played out across snake evolutionary history.

“Our analyses suggest that the most recent common ancestor of all living snakes would have already lost its forelimbs, but would still have had tiny hind limbs, with complete ankles and toes. It would have first evolved on land, instead of in the sea,” said co-author Daniel Field, a Yale Ph.D. candidate. “Both of those insights resolve longstanding debates on the origin of snakes.”

The researchers said ancestral snakes were non-constricting, wide-ranging foragers that seized their prey with needle-like hooked teeth and swallowed them whole. They originated about 128.5 million years ago, during the middle Early Cretaceous period.

“Primate brains, including those of humans, are hard-wired to attend to serpents, and with good reason,” said Jacques Gauthier, senior author of the study, a Yale professor of geology and geophysics, and curator of fossil vertebrates at the Yale Peabody Museum of Natural History. “Our natural and adaptive attention to snakes makes the question of their evolutionary origin especially intriguing.”

Support for the research came from the Yale Peabody Museum of Natural History, the Smithsonian Institution, and the Canadian Natural Sciences and Engineering Research Council.

Additional authors of the study are Timothy Webster, Adam Behlke, Matthew Davis, and Rachel Racicot, all of Yale.

Ugliest Statue in Washington, D.C.

The Temperance Fountain is a fountain and statue located in Washington D.C., donated to the city in 1882 by Henry D. Cogswell, a dentist from San Francisco, California, who was a crusader in the temperance movement.  This fountain was one of a series of temperance fountains he designed and commissioned in a belief that easy access to cool drinking water would keep people from consuming alcoholic beverages.

                                            The hideous Temperance Fountain and Statue

Design

 The fountain has four stone columns supporting a canopy on whose sides the words "Faith," "Hope," "Charity," and "Temperance" are chiseled. Atop this canopy is a life-sized heron, and the centerpiece is a pair of entwined heraldic scaly dolphins. Originally, visitors were supposed to freely drink ice water flowing from the dolphins' snouts with a brass cup attached to the fountain and the overflow was collected by a trough for horses, but the city tired of having to replenish the ice in a reservoir underneath the base and disconnected the supply pipes. 

The inscription reads:
(Base of fish:)
PRESENTED BY
DR. HENRY D. COGSWELL
OF SAN FRANCISCO CAL
(Top of temple:)
TEMPERANCE
FAITH
HOPE
CHARITY

Location

In 1987, it was relocated about 100 feet north [backing it away from Seventh and Pennsylvania Avenue to approximately Seventh and Indiana Avenue] during the renewal by the Pennsylvania Avenue Development Corporation, since the statue was regarded as undesirable from the start.  The PADC created Indiana Plaza, and the Temperance Fountain swapped locations with the monument to the Grand Army of the Republic, which was considered historically more significant.

Today the fountain sits at the corner of Seventh Street and Indiana Avenue, NW, across from [701 Pennsylvania Avenue, a METRO subway entrance and] the National Archives and Navy Memorial, where thousands of tourists and workers walk past daily without noticing it.  The Temperance Fountain has been called "the city's ugliest statue" [in writing by the Washington Post in 2003]. The late NBC correspondent Bryson Rash, writing in Footnote Washington, a 1981 book of capital lore, reported that "these unusual and awkward structures spurred the movement across the country for city fine arts commissions to screen such gifts" prior to funding.  In April 1945, Sen. Sheridan Downey of California introduced a Senate resolution to remove the fountain, but, preoccupied with World War II, Congress ignored the resolution and it died in committee.[

Catallactics versus Economics

Catallactics is a theory of the way the free market system reaches exchange ratios and prices. It aims to analyse all actions based on monetary calculation and trace the formation of prices back to the point where an agent makes his or her choices. It explains prices as they are, rather than as they "should" be. The laws of catallactics are not valyue judtgments, but aim to be exact, objective and of universal validity. It was first used extensively by the Austrian School economist Ludwig von Mises.

Cattallactics is a praxeological theory, the term catallaxy being used by Friedrich Hayek to describe "the order brought about by the mutual adjustment of many individual economies in a market."  Hayek was dissatisfied with the usage of the word "economy" because its Greek root, which translates as "household management", implies that economic agents in a market economy possess shared goals. He derived the word "Catallaxy" (Hayek's suggested Greek construction would be rendered καταλλαξία) from the Greek verb katallasso (καταλλάσσω) which meant not only "to exchange" but also "to admit in the community" and "to change from enemy into friend."

According to Mises (Human Action, page 3) and Hayek it was Richard Whately who coined the term "catallactics". Whately's Introductory Lectures on Political Economy (1831) reads:

“It is with a view to put you on your guard against prejudices thus created, (and you will meet probably with many instances of persons influenced by them,) that I have stated my objections to the name of Political-Economy. It is now, I conceive, too late to think of changing it. A. Smith, indeed, has designated his work a treatise on the "Wealth of Nations;" but this supplies a name only for the subject-matter, not for the science itself. The name I should have preferred as the most descriptive, and on the whole least objectionable, is that of CATALLACTICS, or the "Science of Exchanges."

Also, in a footnote to these sentences, he continues:

“It is perhaps hardly necessary to observe, that I do not pretend to have classical authority for this use of the word Catallactics; nor do I deem it necessary to make any apology for using it without such authority. It would be thought, I conceive, an absurd pedantry to find fault with such words as "thermometer," "telescope," "pneumatics," "hydraulics," "geology," &c. on the ground that classical Greek writers have not employed them, or have taken them in a different sense. In the present instance, however, I am not sure that, if Aristotle had had occasion to express my meaning, he would not have used the very same word. In fact I may say he has used another part of the same verb in the sense of "exchanging;" (for the Verbals in are, to all practical purposes, to be regarded as parts of the verbs they are formed from) in the third book of the Nicom. Ethics he speaks of men who hold their lives so cheap, that they risked them in exchange for the most trifling gain []. The employment of this and kindred words in the sense of "reconcilement," is evidently secondary, reconciliation being commonly effected by a compensation; something accepted as an equivalent for loss or injury.”

It has also been cited that Whately first coined the term in commentary during his Oxford lectures.

Psychiatrist Mark Goulston

Mark Goulston (born February 21, 1948) is a prominent psychiatrist and consultant to major organizations. His book, Just Listen, ranked #1 in six Amazon/Kindle categories, has been translated into 14 languages, reached #1 in Munich and Shanghai, and became the basis of a 2010 PBS special. The Consumers Research Council three times named him one of America's Top Psychiatrists, including in 2011. For over 20 years, he has been Clinical Assistant Professor of Medicine at UCLA's Neuropsychiatric Institute. Goulston has appeared on Oprah, The Today Show, The Phil Donohue Show, CNN, and hosted a PBS pledge drive special. His column Solve Anything with Dr. Mark is nationally syndicated by Tribune Media Services.  He blogs for the Huffington Post, Psychology Today, Fast Company, and Business Insider, and he contributes to the Harvard Business Review.  He frequently gives keynote speeches at women's conferences.  Dr. Goulston lives in Los Angeles with his wife and three children.

Career

Goulston started a private practice. It specialized in suicide, death, and dying, including making house calls, and working with families and couples. After doing psychiatric house calls to dying patients and their family members, he was sought out to work with the surviving family and their businesses.

That expanded to his being a consultant, speaker, trainer and coach to such organizations as IBM, Goldman Sachs, Merrill Lynch, Xerox, Deutsche Bank, Hyatt, Accenture, Astra Zeneca, British Airways, Sodexo, ESPN, Kodak, Federal Express, YPO, YPOWPO India, Association for Corporate Growth, FBI, Los Angeles District Attorney, White & Case, Seyfarth Shaw, UCLA Anderson School of Management, USC, and Pepperdine University.

He has been interviewed, appeared in and/or and written for hundreds of major media, including: the New York Times, Wall Street Journal, Forbes, Fortune, Los Angeles Times, CNN, MSNBC, and HLN.  He also co-hosts the Zo Williams Morning Radio Show.

In addition to the aforementioned Just Listen, Goulston's five books include Get Out of Your Own Way: Overcoming Self-Defeating Behavior, Get Out of Your Own Way at Work…and Help Others Do the Same, The 6 Secrets of a Lasting Relationship, and Post-Traumatic Stress Disorder for Dummies.  His sixth book, Real Influence: Persuade Without Pushing and Gain Without Giving In, co-authored with Dr. John Ullment to be published in 2013 [available now in 2015], has been selected as the lead book for the American Management Association and has also been selected as one of the 30 Best Business Books for 2013 by Soundview Executive Summaries.

Goulston sits on the Board of Advisors at Health Corps (Dr. Mehmet Oz’s foundation) and American Women Veterans, and he is a Fellow of the American Psychiatric Association.  He is also the Co-Founder, Co-Curator and Co-Guardian of Heartfelt Leadership, an effort to bring more humanity and ultimately more profit to the workplace.

Dr. Goulston is also Co-Developer of The Exam Performance Program (R), an eLearning course which teaches students how to be calm, confident and focused so they can perform better and score better on academic exams and standardized tests. The course has been developed to (I) improve student cognitive performance and test scores on academic exams and standardized tests, (II) improve student mindset, self-confidence, self-efficacy, motivation, engagement, retention and academic trajectory, (III) eliminate/prevent test-anxiety and "stereotype-threat", and (IV) motivate STEM achievement, especially in low-income/minority/female/foster-care student groups. The Exam Performance company website and information about the Development Team is at

The Carnival of Venice (song)

The Carnival of Venice is a folk tune popularly associated with the words "My hat, it has three corners" (or in German, Mein Hut, der hat drei Ecken).  A series of theme and variations has been written for solo trumpet, as "show off" pieces that contain virtuoso displays of double and triple tonguing, and fast tempos.

Many variations on the theme have been written, most notably those by Jean-Baptiste Arban, Del Staigers, Herbert L. Clarke for the cornet, trumpet, and euphonium, Francisco Tarrege and Johann Kaspar Mertz for classical guitar, Ignace Gibsone for piano, and –Giovanni Bottesini for double bass.  Chopin’s "Souvenir de Paganini", dedicated to the composer and violin virtuoso Niccolo Paganini, is another variation on this theme. The popular novelty song, “(How Much Is) That Doggie in the Window?”, written and recorded in 1952, is based on the tune. A more recent piece making use of the theme, by Allen Vizzutti, called "The Carnival of Venus," is regarded as one of the most difficult trumpet pieces ever written due to range and technical demands.

The piece has also been arranged for tuba, notably played by John Fletcher and available on the CD The Best of Fletch. Also Roger Bobo on Tuba Libera (cd). Another tubist whose performance of the piece is noteworthy is Oystein Baadsvik, a Norwegian tubist.
