All truth passes through three stages. First, it is ridiculed. Second, it is violently opposed. Third, it is accepted as being self-evident: Arthur Schopenhauer -- In questions of science the authority of a thousand is not worth the humble reasoning of a single individual: Galileo Galilei -- Science is a wonderful thing if one does not have to earn one's living at it: Albert Einstein -- When you have eliminated the impossible, what ever remains, however improbable must be the truth: Sir Arthur Conan Doyle -- We all agree that your theory is crazy, but is it crazy enough? Niels Bohr -- Whenever a true theory appears, it will be its own evidence. Its test is that it will explain all phenomena: Ralph Waldo Emerson -- Since the mathematicians invaded Relativity, I do not understand it myself anymore: Albert Einstein -- I would say that the aether is a medium invented by man for the purpose of propagating his misconceptions from one place to another: W.F.G. Swann: -- Most of the fundamental ideas of science are essentially simple, and may, as a rule, be expressed in a language comprehensible to everyone: Albert Einstein -- Physics is mathematical not because we know so much about the physical world, but because we know so little: Bertrand Russell -- If I could explain it to the average person, I would not have been worth the Nobel Prize: R. P. Feynman -- I do not feel obliged to believe that the same God who has endowed us with sense, reason, and intellect has intended us to forgo their use: Galileo Galilei -- How dare we speak of the laws of chance? Is not chance the antithesis of all law?: Bertrand Russell -- Only two things are infinite, the universe and human stupidity, and I´m not sure about the former: Albert Einstein -- The glory of mathematics is that you don't have to say what you are talking about: Richard Feynman -- Anything is possible if you don´t know what you are talking about: Author Unknown -- In life, everything is relative - except Einstein´s theory: Leonid S. Sukhorukov -- Don´\'t worry about people stealing your ideas. If your ideas are any good, you´ll have to ram them down people´s throats: Howard Aiken --A day will come undoubtedly when the ether will be discarded as useless: H. Poincaré -- First they tell you you´re wrong and they can prove it; then they tell you you´re right but it isn´t important; then they tell you it´s important but they knew it all along: Charles Kettering -- It is not once nor twice but times without number that the same ideas make their appearance in the world: Aristotle -- The opposite of a true statement is a false statement. The opposite of a profound truth may well be another profound truth: Niels Bohr -- A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it: Max Planck -- Euclid taught me that without assumptions there is no proof. Therefore, in any argument, examine the assumptions: Eric Temple Bell -- Half this game is ninety percent mental: Yogi Berra

Abstract:

The researches of the groups lead by Dimas G. de Oteyza published their work - Direct Imaging of Covalent Bond Structure in Single-Molecule Chemical Reactions – in the Science 21 June 2013: 1434-1437. The same work was published online on 30th May 2013 in the edition of Science Express DOI:10.1126/science.1238187] The authors are the teams of Felix Fischer (Department of Chemistry at Berkeley), Michael Crommie (Department of Physics at the same university) and Ángel Rubio (Professor at the UPV/EHU and researcher at the CSIC-UPV/EHU Centre for Physics of Materials and at the Donostia International Physics Center). The leading author of the article is Mr. Dimas Oteyza. They have taken, for the first time, images of individual molecules (oligo–enediyne molecule C26H14 T > 90 °C) as they transform from one condition to another after a complex organic reaction. The images were made by a noncontact Atomic Force Microscope (nc-AFM). Without this detailed images of the structural transformation of the oligo–enediyne molecule C26H14 T > 90 °C it is very hard to predict the unexpected products they got from the reactant. So in their work they propose a transformation pathway from reactant to products. But if we look carefully to the images from the proposed transformation pathway from the reactant to the products, we will find several difficulties. ...
