O video com a melhor explicacao sobre atomos e mecanica quantica basica. E os comentarios na discussao abaixo do video sao interessantes , principalmente do fisico que explica ninguem nunca viu atomos e particulas nos instrumentos da Fisica, apenas campos eletricos.

The most explanatory video about atoms and basic quantum mechanics

This is an email I received recently from the site “Ask a Mathematician, Ask a Physicist”::::::
What are “actual pictures” of atoms actually pictures of?.
Actual pictures of atoms aren’t actually pictures at all. There are a few good rules of thumb in physics. Among the best is: light acts like you’d expect on scales well above its wavelength and acts weird on scales below. In order to take a picture of a thing you need light to bounce … The only thing physicists have actually seen is basically a computer image, not the real image, and second, they observe electric fields, not the particle itself. They do not observe particles themselves; they are able to observe only the field. However this alone does not prove anything, but that the electric energy field exists and that’s about it—no atoms, no photons, no electrons, no quarks. no nothing. So no, particles do not exist. Particles exist only inside mathematical abstractions and nothing more and nothing else. We don’t know what actually exists in the real world, except that there are energy fields—electric, magnetic and all other forms and all other kinds of energy fields. I forgot to add what exactly is visualized with all these microscopes including STM–the scanning tunneling microscope. What is visualized is the charge density of the electric field. Basically you observe vibrations—electric vibrations. You haven’t seen an atom either. You’ve seen an image you assume to be an atom, but it is simply an instrument’s representation of the atom. It is not the atom itself. These techniques aren’t actually “visual” like microscopes we work with in biology classes. Microscopes use lenses and light to help zoom and focus on small objects. Electron microscopes, on the other hand, use quantum scattering theory to construct the shape of small objects, then the data is transferred to a computer to create a model. The wavelengths of visible light ranges on the order of ~370nm to 750nm. These are all MUCH larger than many particles of interest (and way too large to view atoms, which are on the order of Angstroms–0.1nm). Scientists need to be creative to be able to “see” atoms. So, no, scanning tunneling microscopes and atomic force microscopes did not prove the existence of atoms.

Oure Energy:
Also evidence of constant creation are these words: ‘magically bursting forth are quarks spinning billions of times a second as 3 points of light, forming what are called protons and neutrons’. I found these words in the book “The Quantum World” written by the physicist Kenneth Ford. Imagine that. Turns out we are imagination itself since nothing is solid. We are brilliant, concentrated energy images or holograms. In the book “Hands of Light” written by the physicist/healer Barbara Brennan are many pictures of what we look like as holograms/eternal energy beings. Brennan trained herself to see people as holograms.

“Behave,” by Robert Sapolsky. “It’s all in our brains,” or, “It’s just our hormones” are among the many misleading short-hands we use to explain why we do what we do. Sapolsky, a Stanford biologist, shows how astonishing complex the link is between our molecular nature and our lived existence.

“A Crack in Creation,” by Jennifer Doudna and Samuel Sternberg. It’s a chronicle of Doudna’s experience discovering CRISPR, a powerful new gene-editing tool.

“A Different Kind of Animal,” by Robert Boyd. Boyd, a leading anthropologist, offers a wonderfully succinct account of culture as a feature of our species, and how it creates a new set of rules beyond biological evolution for how we can change.

“A Brief History of Everyone Who Ever Lived,” by Adam Rutherford. One of my big obsessions as a reporter is our expanding understanding of our genetic history, thanks to incredible advances like sequencing Neanderthal genomes. Rutherford, a British geneticist and journalist, presents a great survey of this fast-moving field.

“How to Tame A Fox,” by Lee Dugatkin and Lyudmila Trut. Dugatkin and Trut recount a profound experiment that took place in the Soviet Union: researchers bred foxes over a few decades into puppy-like creatures. The transformation may tell us something important about our own genetic changes that made us human.

“Big Chicken,” by Maryn McKenna. Among the things we share with nature are diseases–pathogens that shuttle between animals and humans. McKenna chronicles how our modern meat industry has fostered the evolution of dangerous bacteria that resist our best antibiotics.

End of Science [Paperback]
John Horgan
John Horgan (Author)

› Visit Amazon’s John Horgan Page

Book Description
Publication Date: March 5, 1998
As a writer for SCIENTIFIC AMERICAN, John Horgan has an unsurpassed window on contemporary science, routinely interviewing the scientific geniuses of our times, scientists such as Richard Dawkins, Murray Gell-Mann, Stephen Hawking, Karl Popper and Noam Chomsky. In THE END OF SCIENCE, Horgan displays his genius for getting these larger-than-life figures to be human, whilst also encouraging them to confront the very limits of knowledge. Have the big questions all been answered? Has all the knowledge worth pursuing become known? Will there be a final ‘theory of everything’ that signals the end? Horgan extracts surprisingly candid answers to these and other delicate questions as he discusses God, Star Trek, superstrings, quarks, consciousness and numerous other topics. In a time where scientific rationality is under fire from every quarter, THE END OF SCIENCE is a witty, thoughtful, profound and entertaining narrative which serves as both a critique of and a homage to modern science.

Editorial Reviews Review

John Horgan makes the powerful case that the best and most exciting scientific discoveries are behind us. He states that many scientists today, particularly those he interviewed for the book, are “gripped by a profound unease,” due partially to dwindling financial resources and vicious competition, but increasingly due to the sense that “the great era of scientific discovery is over.” In other words, he argues, the big problems that can be solved have been, and the big ones that haven’t been solved can’t be. Among the celebrated thinkers quoted in this ambitious book are Stephen Jay Gould, Roger Penrose, and John Archibald Wheeler. A concise history of the last 20 years of scientific study introduces his thesis and covers such topics as superstring theory, mathematical topology, and how to distinguish chaos from complexity. –This text refers to an out of print or unavailable edition of this title.

From Publishers Weekly

Scientific American columnist Horgan here interviews an impressive array of scientists and philosophers, who seem sharply divided over the prospects and possibilities of science. Among the pessimists, molecular biologist Gunther Stent suggests that science is reaching a point of incremental, diminishing returns as it comes up against the limits of knowledge; philosopher Thomas Kuhn sees science as a nonrational process that does not converge with truth; Vienna-born thinker Paul Feyerabend objects to science’s pretensions to certainty and its potential to stamp out the diversity of human thought and culture. More optimistic are particle physicist Edward Witten, pioneer of superstring theory (which posits a universe of 10 dimensions); robotics engineer Hans Moravec, who envisions superintelligent creative robots; and physicist Roger Penrose, who theorizes that quantum effects percolating through the brain underlie consciousness. Other interviewees are Francis Crick, Noam Chomsky, David Bohm, Karl Popper, Murray Gell-Mann, Sheldon Glashow, Ilya Prigogine and Clifford Geertz. Despite the dominant doomsaying tone, this colloquium leaves much room for optimism.


Flow: The Psychology of Optimal Experience [Paperback]

Mihaly Csikszentmihalyi’s


Book Description
Series: P.S. | Publication Date: July 1, 2008
Psychologist Mihaly Csikszentmihalyi’s famous investigations of “optimal experience” have revealed that what makes an experience genuinely satisfying is a state of consciousness called flow. During flow, people typically experience deep enjoyment, creativity, and a total involvement with life. In this new edition of his groundbreaking classic work, Csikszentmihalyi demonstrates the ways this positive state can be controlled, not just left to chance. Flow: The Psychology of Optimal Experience teaches how, by ordering the information that enters our consciousness, we can discover true happiness and greatly improve the quality of our lives.


A Teoria Nebular e a Astronomia nos Textos dos Livros Escolares

quinta-feira, março 26th, 2009

Este artigo visa estudar e debater as visoes de mundo transmitidas ou inculcadas nas cabecas das criancas e jovens atraves dos bancos escolares. Existem pessoas que creem no mundo feito por Deus, existem pessoas que creem no mundo sem Deus e existem pessoas que creem no mundo gerado por ancestrais naturais atraves de softwares geneticos. Nao precisa saber muito para concluir como estas visoes de mundo conectam diferentemente os neuronios nos cerebros e produzem pessoas que se comportam diferentes entre si.  Portanto este tema nao e’ metafisico e sim tem enorme influencia no nosso dia-a-dia e determinara’ a nossa sorte no nosso destino.

Vejamos este trecho da revista “The Economist”, May 31st 2003, pag 78:

” Os discos achados em volta de um tipo de jovens estrelas conhecidas como T-Tauri, sao exemplos nos textos dos livros escolares de como se supoe sao formados os sistemas solares. Uma rotatoria nuvem de gaz e poeira inicia a se contrair sob sua propria gravidade. Ela se esquenta no meio enquanto as regioes esxternas se achatam. Enquanto a temperatura no centro aumenta ao ponto de iniciar a fusao nuclear, a poeira na parte achatada se amalgama e adere. Eventualmente, os monmticulos formados pelo amalgama juntos formam os planetas, e o gaz adere como suas atmosferas.

O que os textos destes livros gastam poucas paginas e’ explicando que, na maioria das estrelas tipo T-Tauri, seria tomado muito tempo para conseguir de pequenas particulas de poeira objetos tao grnades acomo aterra, para nao falar de Jupiter. Por volta dos dez milhoes de anos e’ o tempo calculado gasto na formacao de planetas.

Por enquanto, apesar de tao diferentes, os modelos da Matriz e os modelos da Nebular nao se negam mutuamente, ao contrario, as duas podem sobreviver em tal cenario. Bastaria `a Teoria Nebular ver, no meio dos discos de gaz e poeira a presenca de buracos negros e pulsares tais como descritos pela Matriz. Mas existe um outro problema que torna esdte tema complicado e que teremos de refletir muito antes de finalizar o artigo. A Teoria da Matriz apresenta um modelo de um proto-sistema astronomico que na realidade nao existe num dado momento e que e’ formado pelo ciclo vital e constituido pelas diferentes formas de um unico astro e seus acessorios sob este ciclo vital. Portanto nao se trata de um modelo de sistema astronomico, nem solar nem galactico. Para nossos modelos, sistemas solares pouca importancia tem, da mesma forma que, no estudo do corpo humano, os atomos que constituem-no pouca importancia tem. Porem, em relacao ao prototipo, denominado LUCA, ainda nao estou certo se os sistemas solares seriam seus atomos ou suas celulas. Ainda assim, no estudo geral da anatomia humana, pouco se refere as celulas.

Mas vamos voltar e continuar este tema…
