Quantum mechanics does not predict the disappearance of information? The theory of relativity does not predict radiation?

Assume the black hole is a perfect inviscid steady relativistic fluid and that there are no pressure gradients inside the black hole. I don't know if these assumptions makes any sense. I am not an expert on black holes and not an particle physicist; see however "A closer look at the perfect fluid - http://newscenter.lbl.gov/2014/10/02/a-closer-look-at-the-perfect-fluid/ ".  
A shear flow can exist under this assumption. These are however not the only solutions. There are also solutions  which closely resemble electromagnetic waves - this at least says the analysis in this paper http://discontinuous-flow.blogspot.com/2014/11/an-letter-to-royal-society.html

"....In fact, the need to avoid nasty calculations (for lack of a computer) 
has often driven discovery, leading mathematicians 
to find elegant symbolic techniques like calculus...”

I don´t agree please read why.

If someone writes a great app or produces an interesting you tube video, then she or he can make a small fortune. If someone publishes an important mathematical theory which later changes the way we approach economical problems, then no one takes notice for years and this is not at all helpful financially. I think there is no way to get a patent for a mathematical theory. Computer programs are patentable, but there are mathematical theories which cannot be coded - this applies even to such simple application as an non-linear mathematical pendulum with viscosity. No computer program can precisely predict when the pendulum stops - this can be shown.

Wenn die "Kontrolle" des BND durch das Kanzleramt erfolgt und die Kontrolle durch andere Organe praktisch nicht stattfindet, könnte dann ein hypothetischer, zukünftiger Kanzler, den BND dazu benutzen die Opposition in Deutschland zu unterdrücken?

Aus der Wikipedia ( http://de.m.wikipedia.org/wiki/Peter_Altmaier ) über Peter Altmaier:

"Im Oktober 2014 geriet Altmaier parteiübergreifend in die Kritik, nachdem er u.a. an die Mitglieder des NSA-Untersuchungsausschusses ein Schreiben gerichtet hatte, worin er sich eine Strafanzeige gegen Unbekannt für den Fall vorbehielt, dass in Zukunft als geheim eingestufte BND-Unterlagen an die Öffentlichkeit geraten sollten. Dies war in den vorherigen Wochen der Fall gewesen. So wurde etwa über das Geheimdienst-Programm Eikonal berichtet, wonach der BND jahrelang Daten von Deutschen Staatsbürgern an die NSA weitergegeben haben soll. Die Ausschuss-Mitglieder Hans-Christian Ströbele (Grüne) und Martina Renner (Linke) sprachen von einem „Einschüchterungsversuch gegenüber den Ausschussmitgliedern“. Der Ausschussvorsitzende Patrick Sensburg (CDU) stellte sich vor die Abgeordneten. In den Medien wurde das Schreiben als offene Drohung gegenüber dem Ausschuss gewertet."

"And, anyway, there seems to be little that anyone can do about it." does it say in the article. Well - actually  I could add to the climate discussion through an assessment of the mathematical methods used in climate models. At least my education allows this. 

 I think it is very important to understand the limits of the mathematical methods, models and computer programs on which climate reports are based. To understand what can be predicted and what is climate story telling. I think it is also important to understand why it is nearly impossible to get an consensus about the climate change based on climate software and piles of wordy climate reports.

Well -  it is probably impossible to get the necessary information from the climate institutes,  consuming each year several hundred million dollars to produce climate reports, and secondly there is no funding available for such a kind of assessment. The interested is in story's of environmental campaigner and writer and not in the analysis of mathematical models. 


"The scientists and ecologists have done brilliant work over the years, but the essentials are now settled. The climate story has moved into the realms of politics, finance and economics. That is how you would have to write the story to make an impact."


Settled on what? Agreed that we need to reduce carbon dioxide? The earth environment is not a linear system. This means reducing carbon dioxide may have not the same effect as increasing it. Does it really help to reduce carbon dioxide if we destroy each year gigantic areas of forests and increase the ocean pollution, while humans at the same time exploit the maritime system. There is no carbon dioxide problem on a dead planet like Mars. 


From the article: "There is, of course, uncertainty around these numbers. And as we burn fossil fuels ever faster they present a moving target. But what is very clear is that the third figure is much higher than the second — three to five times higher, in fact. Therefore the majority of the oil, gas and coal reserves can never be allowed to be dug up. And fossil-fuel companies should not waste investor capital prospecting for more such reserves."


We need a valid mathematical model which contains the relevant factors and fits on a page! If such an model exists, then  Alan Rusbridger should print these equations it in the guardian. These equation might be more important for our future, than Albert Einstein's famous equation, which was printed in the guardian.

"But not everyone agrees on how to respond. Some protest that divesting from fossil fuels will simply lead to 'bad' money replacing 'good'. Or that they have a duty to maximize returns. Or that keeping money in these companies enables 'good' people to 'engage' and have some influence."


How can we agree on how to respond, based on software programs and wordy reports, which are adapted each year in responds to new experimental findings.

Der Personalchef Horst Neumann (  studierte Wirtschafts- und Sozialwissenschaften, ist Nachfolger von Peter Harz, ehemaliger Lebensgefährte von Andrea Nahles, Professor h.c. der Tongji-Universität Shanghai ) von VW äußert sich über die digital Revolution.

Der Fortschritt hat wohl immer zwei Seiten, eine die dem Menschen mehr Wohlstand und Freiheiten bringt, die andere Seite ist die Versklavung des Menschen und die Entwicklung neuer Waffen wie z.B. Drohnen. Das Beispiel im Beitrag zeigt sehr schön wie zukünftig Menschen zu digital gesteuerten Robotern werden. Man könnte sich natürlich Fragen warum der Arbeiter in den gezeigten Beispiel nicht gleich vollständig durch einen Roboter ersetzt wird. Dies ist jedoch weniger effizient. Durch die Datenbrille werden nicht nur die Fehler des Arbeiters erkannt, sondern es kann auch gleichzeitig ein Leistungsprofil für die Personalabteilung erstellt werden. Fallen die Leistungen des Arbeiters ab, z.B. weil sein Kind erkrankt ist oder seine Frau einen Job in einer anderen Stadt annehmen musste, dann wird einfach der Zeitvertrag nicht mehr verlängert und der Arbeiter ersetzt. Dabei entstehen keine Entsorgungskosten wie bei einem Roboter. Auch entfallen die teuren technische Reparaturen für die digitalen Maschinen.

Noch einen großen Vorteil hat die Industrialisierung 4.0. Dadurch das alles vernetzt ist, lassen sich VW Prozesse besser kopieren. Monatliche Meldungen über die Anfälligkeit digital vernetzter Infrastrukturen werden bei VW entweder ignoriert oder nicht verstanden - ein prinzipielles Problem der digitalen Welt.* Nun - wenn die ersten VW  Kopien in Asien oder Russland gebaut werden, dann ist der Personalchef wohl schon in Rente. Die Frage ist doch wohl eher ob VW in hundert Jahren in Europa noch Autos baut.

* Bitkom: 51 Prozent der deutschen Unternehmen waren bereits von Datendiebstahl, Sabotage oder Spionage betroffen. Besonders interessant für Angreifer ist der Automobilbau. Dies hat eine Umfrage des IT-Branchenverbands Bitkom ergeben; siehe Heiseartikel ( http://www.heise.de/newsticker/meldung/Bitkom-51-Milliarden-Euro-Schaden-jaehrlich-durch-digitale-Wirtschaftsspionage-2609577.html )

Die Digitalisierung zieht in die Industrieproduktion ein und beginnt, die Arbeitswelt umzukrempeln. Im Mittelpunkt der "Industrie 4.0" steht die Vernetzung von Mensch und Maschine.

A unknown reviewer wrote in an review to a proposal:

"Moreover, the questions treated in the proposal are of a level of difficulty only accessible to the world leading analysts. There is no evidence that a applicant belongs to this group today, or plane to cooperate with.
How do you access the scientific originality and feasibility of the project? The question addressed by Einfeldt are fundamental: how can we compute flows which are physically (and analytically) not fully understood? How can we distinguish physical from numerical instabilities? "


I can meanwhile explain some essential differences between numerical and physical instabilities for the example of a viscous, nonlinear mathematical pendulum. A new relation of the inviscid, mathematical pendulum to the harmonic and anharmonic  quantum-mechanical oscillator is  the basis for the analysis.  
The results could also be interesting in relation to the quantum mechanical interpretation of reality. An "uncertainty" results in this example through numerical computability limits. 
The results can now in parts be presented. The complete description requires still an research project to focus my efforts and discuss the results in the scientific community.  

Reading again the referee comments, I am still stunned about the lack of mathematical imagination and his arrogance.

A predictable (linear) climate is important for planing, for the stability of our  society. If the climate enters an unstable phase,  then the human societies will face extreme stress. Linear  political strategies, which governs our society today, will not work anymore.
An unstable  climate could be a mayor problem for the next generation. What are we doing today to help our children to cope with such a possible climate crisis? Using up the available natural resources? Building a green energy infrastructure which might not work during an unstable climate phase? Increasing the financial debt, to be paid of by the next generation? Polluting the environment to be cleanup by our children? Turing an agriculture which worked for millenniums into an industry based on linear short term profits? Building an surveillance infrastructure to control climate riots?

The campaign   http://www.theguardian.com/environment/ng-interactive/2015/mar/16/keep-it-in-the-ground-guardian-climate-change-campaign of the editor in chief Alan Rusbridger from the guardian for "Letting the fossil fuels in the ground" could preserve to some extent fossile energy resources for our children and grand children; see also   http://www.theguardian.com/environment/2015/apr/22/earth-day-scientists-warning-fossil-fuels-     It could make the difference during a climate crisis for them. I think we should at least not create careless pollutions http://www.theguardian.com/environment/2014/aug/04/shell-nigeria-oil-pollution-clean-up-amnesty or using valuable fossil energy resources for luxury, like indoor ski resources in a desert. But this generation will likely even use the last fossil energy resources in the arctic http://www.theguardian.com/environment/2015/may/11/shell-arctic-drilling-alaska-oil-gas

Environmentalists accuse the government of ‘looking the other way’ after US gives green light for Shell to restart drilling for oil and gas

"Die jüngsten Enthüllungen legten nahe, dass das Kanzleramt bei der Aufsicht des BND kläglich versagt habe."

....... das der Einsatz des Bundestrojaners   (http://www.zeit.de/digital/datenschutz/2015-04/bka-bundestrojaner-Überwachung ) durch den BND vom Staat kontrolliert werden kann, dies kann wohl ernsthaft nur die Wahlmehrheit der Bevölkerung glauben, die noch ohne Internet aufgewachsen ist - haben wir früher ja auch nicht gebraucht. Ja früher, da sind Frauen nach der Geburt oft im Wochenbett gestorben, bis ein unbekannter  Wiener Arzt Ignaz Semmelweis die Ursache in den Infektionen erkannt  hat und für bessere Hygiene in den Krankenhäusern kämpfte.   Ein Musterbeispiel für eine methodisch korrekte Überprüfung wissenschaftlicher Hypothesen [2] Zu seinen Lebzeiten wurden seine Erkenntnisse nicht anerkannt und von Kollegen als „spekulativer Unfug“ abgelehnt. Bald werden wir wohl digitale Desinfektionsmittel brauchen, um uns vor den digitalen Krankheiten des BND zu stützen. Aber wahrscheinlich wir vom Staat das digitale Händewaschen verboten, sodass wir uns nicht vor dem illegales Einsatz des Bundestrojaners schützen können und jede Kritik an digitalen Bundesviren  als staatsgefährdender Unsinn abgetan. Die Hypothese des Sicherheitsgewinns durch den Bundestrojaner und der digitalen Überwachung sollte endlich einmal wissenschaftlich überprüft werden.

From the abstract of a paper I looked at this weekend: "We show that such variable time lags are typical for complex nonlinear systems such as the climate, prohibiting straightforward use of correlation lags to infer causation"

Professor Tim Lenton from Geography at the University of Exeter said: “Our new results confirm the prediction of positive feedback from the climate models, the big difference is that now we have independent data based evidence for it.”

An international team of researchers led by Egbert van Nes from Wageningen University (Netherlands) used a novel mathematical insight developed to have a fresh look at the data. The analysis reveals that the glacial cycles experienced by the planet over the past 400,000 years are governed by strong internal feedbacks in the Earth system. Slight variations in the Earth orbit known as Milankovitch cycles, functioned merely as a subtle pacemaker for the process.

“It can be highly misleading to use simple correlation to infer causality in complex systems,” says George Sugihara from Scripps Institution of Oceanography (USA). “Correlations can come and go as mirages, and cause and effect can go both ways as in a kind of chicken and egg problem, and this requires a fundamentally different way to look at the data.”

Why are there almost no comments on this paper? I think it is important. It indicates that the use of statistical methods for non-stable problems can be misleading; an remark by Erwin Schrödinger:

Study based on ice core analysis finds direct evidence of positive feedback operating in climate change whereby global warming amplifies the rise in greenhouse gases resulting in additional warming. University of Exeter scientist Timothy Lenton (pictured) said: “Our new results confirm the prediction of positive feedback from the climate models, the big difference is that now we have independent data based evidence for it".

A video http://youtu.be/BhMSzC1crr0  from the space X CRS-6 first stage landing. During the final phase of the landing, turbulent winds are created through the interaction of the rocket engine thrust with the landing site. The interaction with the stage must be controlled by the automatic landing system. The rocket engines will kick up a lot of dust and little stones, especially on extraterrestrial landing sites. Could this damage the rocket stage; see also http://discontinuous-flow.blogspot.com/2012/04/space-shuttle-lift-off-model.html ?

The Digital World is Merely an Approximation to Reality.
Introduction
I am from a lower middle class family in Hamburg, Germany. Grown up in a quite suburb, with some green spaces, where kids could meet to play soccer, build a treehouse or test there self-made toy kites and bows. Studied mathematics in Hamburg, Germany and received a doctorate in natural science from the  RWTH Aachen, Germany with summa cum laude. Published a few papers which are still quoted after twenty years in scholarly journals. Spend an postdoctoral year in England. Left the scientific field and worked for almost two decades as a big-storage consultant. However, I am probably more an intellectual than a sales person and stopped working as an IT consultant, when this was financially possible.
