Why? Because the "orbitals" are actually solutions of the Schroedinger Wave Equation. They are images or a probability distribution in abstract space. Electrons are not clouds or points, they are things we don't really understand but describe by means of quantum mechanics. So I am deeply suspicious of the picture, because there is no physical object of that shape to image.
I completely agree. Besides, from what I remember from high-school physics, how we "see" *anything* is when light falls on an atom/molecule, these electronics get excited into higher than natural states. When they go back to their natural states, they emit a photon that is characteristic of the material (color etc.). Given this, I don't see (pun intended) how it's possible for such a photograph to be taken.
It's not the essence, but the method of science. The essence of science is that the universe *is* governed by laws; a statement that most scientists would not accept as falsifiable. As scientists, we are happy to accept that a particular theory is falsifiable, but the conclusion from that is always that "we have to look for another theory", not "maybe there is nothing that explains this phenomena".Scientists are always looking for ways to falsify their theories. That is the very essence of science.
"It has been fascinating to watch this phenomenon grow from a little message I tossed off in ten minutes to something that has spread all around the world," said Fahlman [the creator of the smiley].
More than once, Alexis Feldman, the director of the Feldman Realty Group, a commercial real estate company in Manhattan, has been moving forward on a major deal when, she said, "at the 23rd hour, I get an e-mail from the broker saying, 'Sorry, my client is not interested in the space, too bad we couldn't make the big bucks' — then there's a frown face!"
