Shrinking and Other Acts of Sabotage
An illustrated lecture with Petra Lange-Berndt, University College London
Date: Thursday, July 28th
Time: 8:00 PM
Admission: $5
Presented by Morbid Anatomy

Taxidermy is quite literally the incarnation of trophy culture; It is no coincidence that the 19th Century craze for taxidermy coincided with the emergence of the biological sciences, which were, themselves, strongly tied to colonial interests of exploration, exploitation, classification, and reorganization of the world.

Today, this violent story -- as well as the bulk of 19th Century decorative taxidermy, such as heads on shields, armchairs made out of whole bears, elephant footstools or lamp bases adorned with birds of paradise -- are largely absent from public collections and their institutionalized narratives. Also problematic for the serious student of the medium is that, like art conservators or the editors of texts, taxidermists are only successful if there is no visible trace of their work left in the final product.

Tonight's presentation by Petra Lange-Berndt, author of Animal Art: Specimens in Modern and Contemporary Art Practices, 1850-2000, will chase the stories that are woven into the textures of taxidermy by focusing on the fabrication of the nature/cultures in question, and by asking such questions as what kind of politics are attached to these stilled lifes? And how have the power relations encountered in public natural history collections been challenged by modern and contemporary artists?

Petra Lange-Berndt is a lecturer at the Department of History of Art, University College of London. She has published a book in German on Animal Art: Specimens in Modern and Contemporary Art Practices, 1850-2000 (Silke Schreiber, 2009) and just organised a conference on "Taxidermy and Colonial Practice" at the Natural History Museum, London. She likes all kinds of unpopular arts and B-cultures and was co-curator of an exhibition in three parts on "Sigmar Polke: We Petty Bourgeois! The 1970s" at the Kunsthalle in Hamburg (2009-10); her new research is concerned with artists' colonies and communes.

Living Dolls: The Guinness Collection of Mechanical Musical Instruments and Automata at the Morris Museum
A live automata demonstration and illustrated lecture by Jere Ryder, Conservator of the Guinness Collection of Mechanical Musical Instruments and Automata at the Morris Museum
Date: Friday, July 29th
Time: 8:00 PM
Admission: $10
Presented by Morbid Anatomy

The Guinness Collection of Mechanical Musical Instruments and Automata at the Morris Museum in Morristown, New Jersey is one of the finest collections of automata--or moving mechanical toys popular in the 18th Century and 19th Centuries--in the world. Compiled over 50 years by heir to the Guinness beer fortune Murtogh D. Guinness (1913-2002), the collection features scores of immaculately preserved historic automata--many of them produced in 19th Century France--with subjects ranging from snake charmers to magicians, singing birds to anthropomorphic monkeys, Cleopatra in her death throes to a waltz-playing Mephistopheles; it also includes a number of mechanical musical instruments and a variety of programmed media ranging from player piano rolls to pinned cylinders.

Earlier this year, Observatory brought a group to visit this collection in person; for those of you who were unable to join us--or who are hungry more!--we are bringing the automata closer to home. Tonight, we invite you to join Jere Ryder, Conservator of the Guinness Collection of Mechanical Musical Instruments and Automata at the Morris Museum, for a live demonstration of antique automata drawn from both the Guinness Collection and his own personal collection. Mr. Ryder will detail the history of these bewitching toys with an illustrated lecture on their history, show an introductory video, and demonstrate and describe the mechanics that bring them to life.

Bio: As Conservator of the Murtogh D. Guinness Collection of Mechanical Musical Instruments and Automata, Jere Ryder brings a lifetime of involvement within this specialized field. A keen interest developed after being introduced to them by collector parents, whom Mr. Guinness had encountered in the 1950s. He became a family friend, and served as mentor and inspiration for later study within the field. With no specialized teaching institutions dedicated to this particular realm, it was Jere's father, Hughes M. Ryder, who introduced he and his brother to major European families, collections and related museums, assisting his ability to enter into studies/apprenticeships to surviving, established field masters, modern manufacturers and successors of original firms dating to as early as 1800. Throughout junior high and high school he received objects for repair from regional dealers and distributors. He and his brother Stephen created a business partnership in 1973 and since have repaired, restored, appraised and advised for some of the finest collections, acquiring objects on behalf of state and privately-owned museums worldwide, and are internationally renowned for research projects and the ability to source rare instruments offering new paths of study.

Amsterdam-Based Museum Vrolik Closed for Redesign; July 29th Last Day to Visit Before it Closes!



This just in from my friend Laurens De Rooy, curator of the fantastic Amsterdam-based Museum Vrolik, specimens of which are pictured above:

Museum Vrolik to close for ten months
Following in the footsteps of other top museums in Amsterdam, the Vrolik Museum will close for refurbishment and redesign from August 2011 to May 2012. The ten-month overhaul of the anatomy museum of the Academic Medical Centre aims to make the unique collection more appealing to a broader public. The 29th of July will be the last opportunity to visit the museum before it closes.

Museum Vrolik has been one of the AMC’s main attractions since 1984. Its collection includes items that are hundreds of years old, with more than ten thousand anatomical specimens in preservative, human and animal skeletons and skulls, and anatomical models and reconstructions. One of the museum’s treasures is the so-called Hovius display case, an 18th-century case full of bones and skulls ravaged by disease collected by physician Jacob Hovius. Of great scientific importance is the collection of congenital defects, including Siamese twins, cyclops and sirens.

An inspiring environment for all with an interest in disease, health, and the human body
With students of medicine and specialists the museum’s original target group, visitors without a medical background would often find the museum’s layout dated or even a little haphazard. Following its refurbishment, the museum should attract a much broader public, and serve as an easily accessible and inspiring learning environment for all with an interest in disease, health and the human body.
The main exhibition will feature the human body with all of its normalities and abnormalities, but the museum will also look into the history of its many different collections, honouring its original founders. The museum was named after Amsterdam professors Gerardus Vrolik (1775-1859) and his son Willem Vrolik (1801-1863), both anatomists and collectors. After their deaths, the Vrolik collection was expanded by other Amsterdam professors of anatomy.

The best exhibits now on show at the Special Collections UvA
During the closure of the museum a number of the museum’s top exhibits will be temporarily on display at the Special Collections of the University of Amsterdam (located at Oude Turfmarkt) which will host the exhibition ‘the discovery of man’ from 27 September 2011 to 15 January 2012. Together with Museum Vrolik, the Special Collections will exhibit anatomy atlases and specimens and explore how the dissection of the human body has changed man's view of himself.

Pro-Defense, Pro-Israel GOP libertarian for Congress – TX CD-25

From Eric Dondero:

Meet Itamar Gelbman. He is a very unique Republican candidate running for Congress in Texas CD - 15 (north and west of Austin). Gelbman is a native of New York City, but grew up in Israel. He served in varying capacities, with the Tel Aviv police deparment and worked with the Israeli Defense Forces.

He is a libertarian, and member of the Facebook Libertarians in Support of Israel group.

From his website:

I am committed sustaining our strong relationship with Israel.

I will support Israel in its fight for survival and defend their good and right name in the U.N. assemblies.

And on America fighting Terrorism:

We will stand tall in defending our citizens. We will not raise a white flag because a crazy man in Yemen wants to hurt our women and children or another wants to build a nuclear bomb in Iran.

We will ensure co-operation between the different agencies inside the U.S.A and agencies of our allies across the globe such as Australia, Brittan and Israel.

We will ban any person who is affiliated with known terrorist groups such as the Hamas, Hezbollah, Al Qaeda, etc, from entering in the U.S.A.

He is a supporter of the flat tax, extending corporate tax credits, and what he calls a "Heros Tax Credit" for military personell. He is also a diehard defender of the 2nd Amendment.

Conservative Rocker challenges liberal media stereotypes of rightwingers

We can be "kick-ass, fun lovin'" Roller Derby fans; not "grey-suited, pocket protector," Bible thumping Geeks

From BigGovernment.com, "Conservatives, let's change perceptions Now!" by Deanna Murray:

Conservatives are doctors, lawyers, TV directors, actors, journalists, singers, seamstresses, Wall Street tycoons and a ton of other things. Some are church goers, some aren’t. Some believe in God, some don’t. But for some reason, all that is forgotten when we actually tell people where we stand. We just become ‘that conservative over there …’ or …‘that right-wing fanatic.’ All of our coolness disappears and we’re nothing but a label, defined by other people … people we don’t agree with.

But it really does need to be our mission to change perception. Every single person knows perception is reality … and the perception the media puts out there... is tainted, disrespectful and flat out wrong. We need to defiantly say we’re not going to take it any more and we are going to show this country who we are.

Does being a conservative mean we’re not a group of kick-ass fun-loving people? Damn, I don’t think I got that memo … at least I hadn’t when I was out at the roller derby last weekend hollering it up with a bunch of my girlfriends...

If we want to take back our country we have got to show the brainwashed who we really are. That we have a vision and a reason for believing what we do – and we still know how to live. This may seem superficial, but we’ve been painted into a grey-suited box, complete with pocket protector and fire and brimstone Bible …

Libertarian Party of Nebraska to host debate between Republican candidates for US Senate

A "libertarian-conservative Tea Party" festival for central NE

From Eric Dondero:

It's called the Heartland Liberty Fest. The Libertarian Party of Nebraska will be hosting a day-long event in Papillion to celebrate Liberty. The LPN recently regained ballot status, after collecting more than 8,000 signatures. The event is co-hosted by Americans For Propserity, the Republican Liberty Caucus, as well as other libertarian-leaning groups.

The keynote speaker will be Republican Congressman Terry Lee (photo). But a forum featuring the four declared candidates for US Senate will also take place.

From the AP (via The Examiner):

The daylong festival will include musical entertainment and a number of speakers, including KFAB radio talk show host Tom Becka and Libertarian state party chairman Gene Siadek. Republican candidates for U.S. Senate in 2012 will also speak.

The event takes place Aug. 6, and will take place from 11 a.m. through 10:30 p.m. at the Sumtur Amphitheater, Papillion (near Lincoln).

FLORIDA: St. Johns Cty. establishment Republicans fight back against Tea Party insurgents

Upstart Rick Scott reformers vs. the holdover Charlie Crist supporters

From Eric Dondero:

There is an ongoing dispute in St. Johns County (St. Augustine) between local establishment Republicans and elected officials and the St. Johns chapter of the Republican Liberty Caucus together with the Tea Party. The elected Republicans are disgusted with the Tea Party/RLC's continuing references to the Constitution, their anti-government attitudes and theatrics.

From St.Augustine.com, "Local GOP, Tea Party 'at war'
n Tea Party: We're all Republicans n GOP: Fight over control of party":

Many local Republicans dislike the Tea Party's attitude and pressure on officials and staff to attain their agenda. Some say they sometimes ask impertinent and misleading questions, saying, "You work for us," and, "It's our money."

Their protests include signs with scrawled anti-tax slogans and quotes from Founding Fathers. Several silent protests were held by members wearing Sons of Liberty clothing and holding the yellow Gadsden Flag with the words, "Don't Tread on Me."

The two opposing camps stem from internal GOP battles for party positions. The two blocks include supporters of former moderate Republican Governor Charlie Crist and former AG Bill McCollum on one side, and the more Tea Party-oriented supporters of current Governor Rick Scott.

Commissioner tells county employees - "Don't be ashamed" of public service

Continuing:

Long-time GOP veterans say confrontational and theatrical actions turn them off.

Several mainstream Republicans said they don't believe Tea Party rhetoric and added, "There's been a war going on" for control of the party since 2008, when the libertarian-leaning Republican Liberty Caucus tried to take over.

Bob Veit, at the time Executive Committee chairman, said the Caucus was trying to put supporters into vacant precinct captain positions and with increased numbers gain control of the Executive Committee.

One county commissioner recently blew off steam at a local event at what he described as a "verbal assault," by a Tea Partyer.

Later, without mentioning the Tea Party or the incident directly, [Ken] Bryan addressed it at a commission meeting, saying, "There is a trend of anti-government sentiment sweeping this country. I've talked to our employees, and they, too, are feeling it. Some are afraid.

"That is disheartening. I want to tell our employees, 'Don't be ashamed of being a public servant.'"

A world full of children | Gene Expression

The figure to the left is from a new paper in Science, When the World’s Population Took Off: The Springboard of the Neolithic Demographic Transition. It reports the findings from 133 cemeteries in the northern hemisphere in regards to the proportion of 5-19 year old individuals. When calibrated to period when agriculture was introduced into a specific region there seems to be a clear alignment in terms of a demographic transition toward a “youth bulge.” Why? A standard model of land surplus explains part of it surely. When farmers settle “virgin land” there is often a rapid “catch up” phase toward the Malthusian limit, the carrying capacity. Another possibility though is that sedentary populations did not need to space their offspring nearly as much as mobile hunter-gatherers. Whatever the details, the facts remain that the data do point to a shift in the age pyramid during this period. The author wonders as to the possible cultural implications of this. There is an a priori assumption that a young vs. old age profile in a society constrains its choices and channels its energies (e.g., think the “baby boom” generation in ...

Galileons | Cosmic Variance

Over the last year or so I’ve been devoting quite a bit of my time to exploring the origins and implications of a relatively new class of models known as Galileons. These may turn out to be nothing but mathematical curiosities, but while they’re still interesting I thought I’d try to explain what these theories are. This will be a little more technical than typical posts, but I’m hoping to get across the main reasons people are interested in these ideas even if the technicalities become a little much for some readers.

The resurgence of interest in extra dimensional models of particle physics and gravity during the last thirteen years has led to a number of novel approaches to cosmology, one of which is the fascinating idea of Dvali, Gabadadze and Porrati (DGP). In this picture, one begins by thinking of our four-dimensional world as residing on a brane floating in one extra dimension. The difference between this and other extra-dimensional models is that one imagines gravity as being described by a sum of the action for general relativity in 5d, and a 4d version just defined on the brane. This is rather technical, I know, but the main point is that gravity is described by an unusual but deceptively simple action. We, of course measure our world to be four-dimensional, and so the relevant question to ask of theories like this one is how the extra-dimensional physics manifests itself in the four-dimensional world.

As you might expect, this is a complicated issue. There is of course, the way in which the dynamics of four-dimensional gravity differ from that one would expect from pure General Relativity (GR). Furthermore, there are parts of the five dimensional gravity theory that manifest themselves as fields other than the graviton in four dimensions. One of these is a scalar field that can be interpreted as describing the bending of the brane in the extra dimension, and whose dynamics are bound up with those of the graviton in a complex way.

Now, surprisingly, one can learn quite a lot about this theory of modified gravity by doing away with the gravitational interactions all together! This so-called decoupling limit happens by taking the masses describing the strength of the gravitational interactions to infinity, while keeping a special combination of them – the one describing the strength of the self-interactions of the scalar field – constant. This limit is interesting because it isolates the dynamics of the scalar field, and nothing else. Given that what remains is a scalar field theory in four dimensions, one might guess that a host of possible terms would be allowed, and that their behavior would be well-understood; after all, scalar field theories have been studied for a long time and in great detail. However, it turns out that the symmetries of the DGP model, from which this theory originates, lead to an extremely restrictive form of the action – a scalar field theory with a single complicated derivative interaction, obeying the galilean symmetry under which the action is invariant when derivatives of the field are shifted by a constant vector.

I could go on to discuss only this theory, as a way to learn more about the DGP model. However, the realization that there existed a previously unconsidered symmetry of scalar field theories led Nicolis, Rattazzi and Trincherini to consider abstracting the symmetry, and asking what other terms may be allowed for scalar fields. And, remarkably, there turn out to only be five! In this abstracted scalar field theory we refer to these terms as the galileon terms, and to the scalar field itself as the Galileon. In a very nice paper, de Rham and Tolley later showed how these extra terms can also arise from their own actions for a brane living in a flat five-dimensional space. But for now, let’s just focus on the Galileons as interesting new four-dimensional scalar field theories.

I’m not going to write down the mathematical form of these terms here, but there are a number of properties they have that should illustrate why a number of people in the community have found them sufficiently interesting to warrant further study.

  1. The Galileon terms involve higher derivatives, but there equations of motion are only second order in time, and hence they avoid some well-known proofs of instability that plague a lot of higher derivative systems.
  2. There exists a range of energy scales over which the Galileon terms are important, and hence higher derivatives are important, yet quantum mechanical effects are irrelevant, and classical physics holds.
  3. The Galileon terms are unrenormalized! Their coefficients pick up no modifications from quantum corrections arising from other Galileon terms!

This last feature hints at a number of possible applications in cosmology. For example, cosmic acceleration, either in the early or the late universe, typically requires scalar fields with dynamics that are finely tuned, and hence are easily perturbed by quantum corrections. There is therefore the possibility that Galileons may lead to a natural way to achieve such behavior.

A number of authors have begun exploring these possibilities, and my collaborators and I have our eyes on them also. Before that, however, we’ve been spending a significant amount of time trying to understand how the Galileon idea might fit into more general frameworks. We’ve explored multi-Galileon theories, that may arise from the types of gravity action I described earlier, but with more than a single extra dimension. And more recently we’ve expanded on the idea the such theories arise from branes floating in a flat five-dimensional spacetime to show how entirely new Galileon-like theories arise whenever we have the same types of actions for a brane floating in a more general bulk with a number of special symmetries.

Back in April, we held a mini-workshop at the Center for Particle Cosmology at Penn, attended by the majority (but not all, unfortunately) of people in the world working on these ideas. We left that meeting with a bunch of new ideas, working on which has occupied much of my summer. When they get worked out, I’ll tell you more about them.

It is much to early to know if the Galileon idea will help with any of the cosmological and particle physics problems it may be suited to. They’ve been turning up in a variety of surprising and fascinating ways even since our workshop, but that doesn’t necessarily mean anything. But whatever the answer is, we’re learning things, and the process is wonderful fun.


Thermistor Question

I have a dead switch mode psu from a network switch. Closer examination shows that one of the components I need to replace is a Thermistor.

Knowing very little about Thermistors I read up some and have concluded that the item in question is NTC but I have yet to find a list/chart that would enable
