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
Amazon.com 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

Amazon

http://www.amazon.com/Flow-Psychology-Experience-Mihaly-Csikszentmihalyi/dp/0061339202

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…
