Evolution computes via the via negativa. Try everything and the failures eliminate themselves, selecting themselves out because they never had a chance. We want to know why the amplitude world is more effective than the classical world.
Via negativa and logical confinement. Reason is not confined by walls or pressure vessels but by the fact that unreason is self contradictory and collapses because of that, just as unsound structures fall down [and we all die] selected out by inconsistency and reality.

So today we are thinking of the quantum mechanics of fundamental particles as the interactions of players in an orchestra with instruments which provide relatively simple superpositions of vectors. We add vocalists to get the highly complex time ordered sequences ft time evolutions which give us atoms.

Toward utopia? Reality based salvation.
As Aquinas puts it, once we have got the vision of god, all our desires are filled, and so, presumably, we desire no more. I am feeling a bit like this. My book is in hand, just requiring work to finish, and I am in effect sitting back and admiring it as I have my newborn children.

Edelman, Shimon, The Happiness of Pursuit: What Neuroscience Can Teach Us About the Good Life, Basic books 2012 Jacket: ' "The ancient injunction to 'Know thyself' gets a lively update in Shimon Edelman's eclectic examination of 'knowing' and 'self' through the lens of twenty-first century cognitive science. Its human to wander thoughtfully through real and imaginary landscapes, learning as we go—this is happiness, embodied in Edelman's witty odyssey, which provokes the very pleasures it describes.'

Its assimilation requires the reconstruction of prior theory and the re-evaluation of prior fact, an intrinsically revolutionary process that is seldom completed by a single man, and never overnight.'

Stewart, Michael, Keynes and After, Penguin 1999 'Amazing how such a small book could give so much information about an economic theory that changed the world. In "Keynes and After," Michael Stewart does not waste any words in telling the reader how revolutions in thought occur when the prevailing theory can no longer be reconciled with the observable facts. That expression (in the "conclusion" in the book) could itself be an excellent thought for the current global politicians who seem to be clueless and not seeing the observable facts as to how to save the global economy. . . .

Collins, Scott L, "Biodiversity Under Global Change", Science, 326, 5958, 4 December 2009, page 1353-1354. 'Many common plant species, such as prairie grasses, have evolved traits for the efficient capture and use of two key resources that limit terrestrial productivity: nitrogen (N) and carbon dioxide (CO2). Over the past 60 years, human activity has vastly increased the availability of these resources. Atmospheric CO2 concentration has increased by 40%, and N availability has more than doubled. These changes are likely to have important consequences for species interactions, community structure, and ecosystem functioning. On page 1399 of this issue, Reich investigates one important consequence, biodiversity loss, based on a long-term elevated CO2 and nitrogen fertilization experiment '. back |
Sussman, Michael R, George N Phillips Jr, "How Plant Cells go to Sleep for a Long, Long Time", Science, 326, 5958, 4 December 2009, page 1356-1357. 'Seeds are plant spores—desiccated, dormant cells in which metabolism and growth have been drastically slowed, so that the organism can wait out adverse conditions. This is especially important for plants, which cannot run away from environmental threats. Instead of motility, they use dormancy to outlast adversarial conditions caused by pathogens or severe weather. Indeed, some seeds remain viable for hundreds of years. On page 1373 of this issue, Nishimura et al. (1) and four other groups (2–5) report the initial biochemical mechanisms that allow the complex cellular machinery of this multicellular eukaryote to live for so long in a dormant state.'. back |

Composition of the human body - Wikipedia, Composition of the human body - Wikipedia, the free encyclopedia, 'The composition of the human body can be looked at from the point of view of either mass composition, or atomic composition. To illustrate both views, the human body is ~70% water, and water is ~11% hydrogen by mass but ~67% hydrogen by atomic percent. Thus, most of the mass of the human body is oxygen, but most of the atoms in the human body are hydrogen atoms.' back |

The paper, by David Hope of the London School of Economics and Julian Limberg of King’s College London, found that such measures over the last 50 years only really benefited the individuals who were directly affected, and did little to promote jobs or growth.
“Policy makers shouldn’t worry that raising taxes on the rich to fund the financial costs of the pandemic will harm their economies,” Hope said in an interview.' back |
Fiber bundle - Wikipedia, Fiber bundle - Wikipedia, the free encyclopedia, 'In mathematics, and particularly topology, a fiber bundle (or, in British English, fibre bundle) is a space that is locally a product space, but globally may have a different topological structure. Specifically, the similarity between a space E and a product space B × F is defined using a continuous surjective map
π: E → B
that in small regions of E behaves just like a projection from corresponding regions of B × F to B. The map π, called the projection or submersion of the bundle, is regarded as part of the structure of the bundle. The space E is known as the total space of the fiber bundle, B as the base space, and F the fiber.' back |

Nous - Wikipedia, Nous - Wikipedia, the free encyclopedia, 'Nous . . . , sometimes equated to intellect or intelligence, is a philosophical term for the faculty of the human mind which is described in classical philosophy as necessary for understanding what is true or real. The three commonly used philosophical terms are from Greek, νοῦς or νόος, and Latin intellectus and intelligentia respectively. To describe the activity of this faculty, apart from verbs based on "understanding", the word "intellection" is sometimes used in philosophical contexts, and the Greek words noēsis and noein are sometimes also used. This activity is understood in a similar way, at least in some contexts, to the modern concept intuition.' back |

The unit specializes in working with chemical weapons, Bellingcat said.
“I know who wanted to kill me,” Navalny said in a video message about Bellingcat’s joint investigation with Russia’s Insider website, Germany’s Der Spiegel news magazine and CNN. “I know where they live.

'They're casting their problem on society. And, you know, there is no such thing as society. There are individual men and women, and there are families. And no government can do anything except through people, and people must look to themselves first. It's our duty to look after ourselves and then, also to look after our neighbour.

Marty McCarthy, Invasive Species Council highlights conflict of interest in Queensland biosecurity system, calls for more indpendence, 'Currently, the state's Department of Agriculture manages pest and disease incursions and is responsible for the control and eradication of them.
However, in a submission to the Biosecurity Capabilities Review, the Council said more money was spent controlling agricultural pests that posed a commercial risk at the expense of environmental ones.
The Council's Andrew Cox said future pest and disease decisions needed to be made independently of the Department of Agriculture to remove any conflict of interest or favouritism.' back |

NNSA is responsible for managing the nation's nuclear weapons, and while it gets the least attention, it takes up the vast majority of DOE's budget. Similarly, the Sandia and Los Alamos National Labs conduct atomic research related to both civil nuclear power and nuclear weapons. The Office of Secure Transportation is tasked with moving enriched uranium and other materials critical for maintaining the nuclear stockpile. ' back |
Nicene Creed - Wikipedia, Nicene Creed - Wikipedia, the free encyclopedia, 'The Nicene Creed (Greek: Σύμβολον τῆς Νίκαιας, Latin: Symbolum Nicaenum) is the profession of faith or creed that is most widely used in Christian liturgy. It forms the mainstream definition of Christianity for most Christians.
It is called Nicene because, in its original form, it was adopted in the city of Nicaea (present day Iznik in Turkey) by the first ecumenical council, which met there in the year 325.
The Nicene Creed has been normative for the Catholic Church, the Eastern Orthodox Church, the Church of the East, the Oriental Orthodox churches, the Anglican Communion, and the great majority of Protestant denominations.' back |
Nicholas Kristof, Take my quiz on religion, 'Donald Trump's proposal to bar Muslims from the United States may be a gift to Islamic State recruitment and a grotesque echo of the sentiment behind the Chinese Exclusion Act and the internment of Japanese-Americans. But, like those earlier spasms of exclusion, the Trump proposal has plenty of supporters.
In one recent poll, more than three-quarters of Republicans said Islam was incompatible with life in the US, where there is a widespread perception that Islam is rooted in misogyny and violence, incorrigible because it is rooted in a holy text that is fundamentally different from others.' back |
NYT Editors, Normalizing Carnage: Democracy vs the National Rifle Association, '. . . studies have shown that, here in America, states and municipalities with more gun restrictions have fewer gun-related deaths. . . . studies have also shown that people who live in households with guns are less safe overall than those who live in households without them. In short, the politics of gun control may be complicated, but the epidemiology is surprisingly simple: all other things being equal, more guns mean more bloodshed.. back |
Phase space - Wikipedia, Phase space - Wikipedia, the free encyclopedia, 'In mathematics and physics, a phase space, introduced by Willard Gibbs in 1901, is a space in which all possible states of a system are represented, with each possible state of the system corresponding to one unique point in the phase space. For mechanical systems, the phase space usually consists of all possible values of position and momentum variables. . . .' back |
Sarah Lipton, The Words That Killed Medieval Jews, 'Ferocious anti-Jewish rhetoric began to permeate sermons, plays and polemical texts. Jews were labeled demonic and greedy. In one diatribe, the head of the most influential monastery in Christendom thundered at the Jews: “Why are you not called brute animals? Why not beasts?” Images began to portray Jews as hooknosed caricatures of evil.
The first records of large-scale anti-Jewish violence coincide with this rhetorical shift. Although the pope who preached the First Crusade had called only for an “armed pilgrimage” to retake Jerusalem from Muslims, the first victims of the Crusade were not the Turkish rulers of Jerusalem but Jewish residents of the German Rhineland.' back |
Socrates - Wikipedia, Socrates - Wikipedia, the free encyclopedia, Socrates (. . . 470/469 – 399 BC) was a classical Greek (Athenian) philosopher credited as one of the founders of Western philosophy. He is an enigmatic figure known chiefly through the accounts of classical writers, especially the writings of his students Plato and Xenophon and the plays of his contemporary Aristophanes. . . .
Through his portrayal in Plato's dialogues, Socrates has become renowned for his contribution to the field of ethics, and it is this Platonic Socrates who lends his name to the concepts of Socratic irony and the Socratic method, or elenchus. . . . Plato's Socrates also made important and lasting contributions to the field of epistemology, and his ideologies and approach have proven a strong foundation for much Western philosophy that has followed.' back |

Turing machine - Wikipedia, Turing machine - Wikipedia, the free encyclopedia, A Turing machine is a hypothetical device that manipulates symbols on a strip of tape according to a table of rules. Despite its simplicity, a Turing machine can be adapted to simulate the logic of any computer algorithm, and is particularly useful in explaining the functions of a CPU inside a computer.
The "machine" was invented in 1936 by Alan Turingwho called it an "a-machine" (automatic machine). The Turing machine is not intended as practical computing technology, but rather as a hypothetical device representing a computing machine. Turing machines help computer scientists understand the limits of mechanical computation.' back |
Vatican Museums, Propaganda Fide, 'Propaganda Fide
It is the Department (Congregation) of the Holy See founded in 1622 by Pope Gregory XV with the double aim of spreading Christianity in the areas where the Christian message had still not arrived and of defending the patrimony of faith in those places where heresy had caused the genuineness of the faith to be questioned. Propaganda Fide was therefore, basically, the Congregation whose task it was to organize all the missionary activity of the Church. Through a provision of John Paul II (in order to better define its tasks), since 1988 the original Propaganda Fide has been called the "Congregation for the Evangelization of Peoples".
