Negentropy – Wikipedia

The negentropy has different meanings in information theory and theoretical biology. In a biological context, the negentropy (also negative entropy, syntropy, extropy, ectropy or entaxy[1]) of a living system is the entropy that it exports to keep its own entropy low; it lies at the intersection of entropy and life. In other words, negentropy is reverse entropy. It means things becoming more in order. By ‘order’ is meant organisation, structure and function: the opposite of randomness or chaos. The concept and phrase “negative entropy” was introduced by Erwin Schrdinger in his 1944 popular-science book What is Life?[2] Later, Lon Brillouin shortened the phrase to negentropy,[3][4] to express it in a more “positive” way: a living system imports negentropy and stores it.[5] In 1974, Albert Szent-Gyrgyi proposed replacing the term negentropy with syntropy. That term may have originated in the 1940s with the Italian mathematician Luigi Fantappi, who tried to construct a unified theory of biology and physics. Buckminster Fuller tried to popularize this usage, but negentropy remains common.

In a note to What is Life? Schrdinger explained his use of this phrase.

Indeed, negentropy has been used by biologists as the basis for purpose or direction in life, namely cooperative or moral instincts.[6]

In 2009, Mahulikar & Herwig redefined negentropy of a dynamically ordered sub-system as the specific entropy deficit of the ordered sub-system relative to its surrounding chaos.[7] Thus, negentropy has SI units of (J kg1 K1) when defined based on specific entropy per unit mass, and (K1) when defined based on specific entropy per unit energy. This definition enabled: i) scale-invariant thermodynamic representation of dynamic order existence, ii) formulation of physical principles exclusively for dynamic order existence and evolution, and iii) mathematical interpretation of Schrdinger’s negentropy debt.

In information theory and statistics, negentropy is used as a measure of distance to normality.[8][9][10] Out of all distributions with a given mean and variance, the normal or Gaussian distribution is the one with the highest entropy. Negentropy measures the difference in entropy between a given distribution and the Gaussian distribution with the same mean and variance. Thus, negentropy is always nonnegative, is invariant by any linear invertible change of coordinates, and vanishes if and only if the signal is Gaussian.

Negentropy is defined as

where S ( x ) {displaystyle S(phi _{x})} is the differential entropy of the Gaussian density with the same mean and variance as p x {displaystyle p_{x}} and S ( p x ) {displaystyle S(p_{x})} is the differential entropy of p x {displaystyle p_{x}} :

Negentropy is used in statistics and signal processing. It is related to network entropy, which is used in Independent Component Analysis.[11][12]

There is a physical quantity closely linked to free energy (free enthalpy), with a unit of entropy and isomorphic to negentropy known in statistics and information theory. In 1873, Willard Gibbs created a diagram illustrating the concept of free energy corresponding to free enthalpy. On the diagram one can see the quantity called capacity for entropy. This quantity is the amount of entropy that may be increased without changing an internal energy or increasing its volume.[13] In other words, it is a difference between maximum possible, under assumed conditions, entropy and its actual entropy. It corresponds exactly to the definition of negentropy adopted in statistics and information theory. A similar physical quantity was introduced in 1869 by Massieu for the isothermal process[14][15][16] (both quantities differs just with a figure sign) and then Planck for the isothermal-isobaric process.[17] More recently, the Massieu-Planck thermodynamic potential, known also as free entropy, has been shown to play a great role in the so-called entropic formulation of statistical mechanics,[18] applied among the others in molecular biology[19] and thermodynamic non-equilibrium processes.[20]

In risk management, negentropy is the force that seeks to achieve effective organizational behavior and lead to a steady predictable state.[21]

In 1953, Lon Brillouin derived a general equation[22] stating that the changing of an information bit value requires at least kT ln(2) energy. This is the same energy as the work Le Szilrd’s engine produces in the idealistic case. In his book,[23] he further explored this problem concluding that any cause of this bit value change (measurement, decision about a yes/no question, erasure, display, etc.) will require the same amount of energy.

TMG 2010 rewriting original host headers when … – Extropy

I found a strange behavior with TMG 2010 when publishing a website. It appears to rewrite URLs sent outbound to clients when the “send original host header is sent” under certain conditions. Here are those conditions:

Here is precisely what I encountered:

So by process of elimination I found that this appears to be TMG not affecting any host header inbound, nor affecting the alternate URLs outbound.This appears to affect only the main URL outbound, as TMG appears to be rewriting the protocol part of the header when the submitted form returns a redirect from http to https (changing https back to http).

Fixes: Uncheck the “send original host header…” flag and all functionality works correctly. I don’t think this is as “clean”, because it means that TMG touches every request and changes the host header to the internal host header, however on the IIS bright-side this means the web server will see the same host header no matter what clients request (normalization). The only caveat is that if you wanted to use an internal URL (instead of IP address) for the site that was the same as the external URL it would either not work, or would require a DNS trick on TMG to force it. Or, you could just change the internal URL to something else (not used).

TMG proxy background:

This isn’t so much of a bug in TMG as a “feature”. TMG is designed to allow external access to internal resources. I’ve found that it makes a powerful and flexible reverse proxy server, you just have to contend with a few “features”. TMG’s basic design-premise is based on rewriting URLs that are normally only internally visible, to URLs that are externally visible. This means that TMG errs towards the side of rewriting in exception cases, which this appears to be. This methodology appears to assume that the web servers are dumb, and don’t know about external URLs. This premise is fine, except when it is necessary for the web server to perform some type of functionality that requires a complex redirect based on a user action (such as switching to https when a user logs in). TMG assumes that the redirect is internal in nature and blocks the redirect in favor of maintaining the original URL and same-protocol bridging (or more accurately not bridging). This appears to only be an issue when TMG is confused by using the external URL as the internal URL (same as listener and client requests). This shouldn’t be an issue when you specify that TMG uses an IP address for the internal site, however it appears that MS has designed TMG to be “smarter” and “more helpful” by performing host header translation outbound, even when you request it no to do so…

Knights of Unicron (SG) – Transformers Wiki – TFWiki.net

The Knights of Unicron are a heroic Autobot subgroup from the Shattered Glass continuity family.

The Knights of Unicron were once evil Autobots, but the benevolent god of extropy Unicron reformatted them into his agents of peace. Now, they serve truth and justice across known space. Their members are:

Following their defeat at Decepticon City on Earth, Optimus Prime’s forces retreated aboard Sky Lynx for Cybertron. Memory’s Splinter Midway through, however, Sky Lynx announced that they would have to lighten the load. Rodimus took the opportunity to dump Optimus, Brawn, Prowl, Inferno, and Ratchet out the airlock. The five badly injured Autobots then found themselves in the presence of Unicron. Familiar Reflections Now dominated by good due to the Shroud, the god of extropy offered Optimus and his troopers truth and enlightenment. After Unicron showed Optimus a vision of his greatest victory, Prime accepted, and Unicron healed and reformatted them. The newly-formed Knights were then sent to Cybertron to stop Rodimus’s chaos. Arriving in Rodimus’s throne room, the Autotroopers took on the evil Autobots while Nova went head to head with Rodimus. Nova succeeded, sending Rodimus tumbling down into the depths of Cybertron. Restoration The Knights soon had the Autobots arrested, but Unicron contacted Nova to warn him that a greater threat awaited. Cybertron then seemingly began to fall apart. While the Knights barely maintained their footing, Rodimus reappeared and ordered his Autobots to evacuate. Cybertron then completed its transformation into the physical form of the Cybertronians’ creator-god, Primus. Awakened by Rodimus and dominated by evil due to the Shroud, the dark Primus observed the nearby dimensionally-displaced Earth and tried to destroy it. However, Earth revealed itself as another Transformer god, Primus’s sister Gaea. As the titans clashed, the Knights came to Gaea’s aid, taking out Primus’s eyes. Gaea then destroyed Primus and transformed herself into a new Cybertron as a home to both heroic Autobot and heroic Decepticon. The Knights became the guardians of the new joint society as a new age of peace dawned. The Future Buried…

extropy – Wiktionary

English[edit] Etymology[edit]

First coined to serve as an antonym of entropy, substituting its en- element (representing the prepositional prefix (en), en, in in its Ancient Greek etymon (entropa), entropia, a turning towards) with ex- (representing the Ancient Greek (ex), ex, out of, from); because (ex) takes the form (ek) when prefixed to an element beginning with (t), the analogical spelling is ectropy (or, alternatively, ektropy), as if after the Ancient Greek * (ektropa, a turning out of).

Extropy – definition of extropy by The Free Dictionary

Extropy SHIFT>

Extropy is the idea that human intelligence and technology will enable life to expand in an orderly way throughout the entire universe. Extropy expresses a metaphor, rather than serving as a technical term, and so is not simply the opposite of entropy. Extropy presents the idea that advances in science and technology will some day let people live indefinitely and that humans alive today have a good chance of seeing that day. It also describes a pragmatic consilience of transhumanist thought guided by a proactionary approach to human evolution and progress.

Extropian thinking places strong emphasis on rational thinking and practical optimism. These principles do not specify particular beliefs, technologies, or policies. Extropians share an optimistic view of the future, expecting considerable advances in computational power, life extension, nanotechnology and the like.

Many extropians foresee the eventual realization of unlimited maximum life spans, and the recovery, thanks to future advances in biomedical technology, of those whose bodies/brains have been preserved by means of cryonics or some similar method. Extropy emphasizes finding solutions to problems of the human condition, as well proactively considering potential unwanted side-effects of new technologies.

It should be understood that since the term extropy is a metaphor, a name for a moderately integrated group of values and attitudes, and it is not a force or a thing or a single value or principle; it cannot be measured.

Principles of Extropy

Perpetual Progress

Extropy means seeking more intelligence, wisdom, and effectiveness, an open-ended lifespan, and the removal of political, cultural, biological, and psychological limits to continuing development. Perpetually overcoming constraints on our progress and possibilities as individuals, as organizations, and as a species. Growing in healthy directions without bound.

Self-Transformation

Extropy means affirming continual ethical, intellectual, and physical self-improvement, through critical and creative thinking, perpetual learning, personal responsibility, proactivity, and experimentation. Using technology in the widest sense to seek physiological and neurological augmentation along with emotional and psychological refinement.

Practical Optimism

Extropy means fueling action with positive expectations individuals and organizations being tirelessly proactive. Adopting a rational, action-based optimism or proaction, in place of both blind faith and stagnant pessimism.

Intelligent Technology

Extropy means designing and managing technologies not as ends in themselves but as effective means for improving life. Applying science and technology creatively and courageously to transcend natural but harmful, confining qualities derived from our biological heritage, culture, and environment.

Open Society information and democracy

Extropy means supporting social orders that foster freedom of communication, freedom of action, experimentation, innovation, questioning, and learning. Opposing authoritarian social control and unnecessary hierarchy and favoring the rule of law and decentralization of power and responsibility. Preferring bargaining over battling, exchange over extortion, and communication over compulsion. Openness to improvement rather than a static utopia. Extropia (ever-receding stretch goals for society) over utopia (no place).

Self-Direction

Extropy means valuing independent thinking, individual freedom, personal responsibility, self-direction, self-respect, and a parallel respect for others.

Rational Thinking

Extropy means favoring reason over blind faith and questioning over dogma. It means understanding, experimenting, learning, challenging, and innovating rather than clinging to beliefs.

Extropy – Evernote User Forum

Probably the most useful feature for me in Evernote is dumping emails into it that require me to do something (think, respond, follow-up, etc.). I use Mail Butler and sometimes Alfred for this, and I get a nice “message:…” link in the note that lets me get back to that email in my mail application to reply, read more context in the thread, etc. The most useful missing feature is the ability to add links to other emails into notes. When you create a link in the note text (^k or menus), the URL police turn the “OK” button grey for links that they don’t agree with, stopping me from pasting a “message:…” link as the hypertext. I get these links from a simple Applescript I wrote that copies the link for the message selected in mail. Thus, it is impossible for me to make a note like this: Mars Mission Select launcher Falcon Heavy specifications (this would contain an evernote://.. link to that note) Select crew 4 candidates have emailed so far: Elon Musk, Bill Gates, Vladimir Putin, Buzz Aldrin Those underlined links would link to the email messages in Mail. I want to do this rather than bring those messages into Evernote because they are evolving threads, and I want to be able to quickly jump to that thread in Mail rather than store a snapshot of it. I understand that Evernote doesn’t want to include links that might not work everywhere, but these links (“message:…”) do work everywhere I need them to. All my Macs (3), both iPads and my iPhone. So, Specific request: please allow “message:…” links in text links General request: please allow me to put anything I want in the text links. I’ll take responsibility if they don’t work somewhere.

Greydon Square Extropy Lyrics | Genius Lyrics

[Verse 1: Greydon] Waves. A behavior in space-time. Vibration. Sound. Oscillation Light. A fancy way of saying electromagnetic radiation Sight. Visual perception. The ability to discern direction Might. What I bring to the mic. When these emcees gonna learn they lesson? …Line throwin’ mind blowing rhyme poet, that flows While you condone your time stolen Astro. Greek. Meaning star. Flaming plasma ball Equations embedded in space-time while adinkran images mask it all Some of us were passed down martial science from the ancients A one inch punch? I could pull a strike off from the planck length ….Among humans, the differences are marginal Free to move at light anywhere, like any massless particle Chart and go, spark and blow dro, then explain a parallax And how a nearer object moves faster than when its there in the back We deal in octaves Physics, math, chemistry, logic Enemy? stop it. Youre better off described as an entropy novice

[Chorus] Wake up They want to know how far into the future youre gonna take them Then want to know just.. how stark the view is through an ape lense Cause theyll only respond to perpetual progress if its flagrant Complacent with life, yet are fearful of death

[Verse 2: Greydon] Let me see, while you still stuck on the collection fee Im wreckin’ beats, when you check for me Mark the box that says, Extra heat! Technically. Peep it, its like trying to keep a secret the DMT trip When youve already had ego death and your heart is ready to release it This oceanll make you seasick But at least you under the night sky Not only in the right place, but even born in the right time To make music, dj, and write rhymes Everyone has a crew, but no ones doing it like mine Verbal graffiti we spray and hurl in your city The ruckus we create interrupts the early committees …Theyll scramble in panic thinking that its a takeover But in the context of #GU, were just a placeholder The most powerful of us havent even been born yet Formed yet Why do you think they call us the Hornet’s Nest? But, we wont stop until we see, civilization level Z And the only language wed have is Peace, knowledge, and extropy

[Chorus] (x2) Wake up They want to know how far into the future youre gonna take them Then want to know just.. how stark the view is through an ape lense Cause theyll only respond to perpetual progress if its flagrant Complacent with life, yet are fearful of death
