‘here’ and ‘there’      Molecular animation draws on publicly available resources like Protein Data Bank, a database containing three-dimensional coordinates for all of the atoms in a protein; many of over 63 thousand proteins in the database can be easily rendered and animated. While molecular animation, a rapidly growing field that brings the power of cinema to biology, certainly will play a significant part in education and science popularization, the ability to animate molecules really gives biologists a chance to think about them in a whole new way.

This ‘eyes on’ approach (in spite of the fact that events depicted are below the wavelength of light) is in contrast to physicists who are, for a too long time now, entrenched into the view of Nature from human dimensions. Not necessarily a problem in itself, it has been twisted into an unfounded cog- nitive approach to Nature by the army of physicist who believe that they do ‘pure physics’ only. They are unaware of their stray from the basic philosophical assumptions of the physical laws they use.

Take, for instance, the Heisenberg’s principle of uncertainty. All it says is that, because our act of measurement in the microworld introduces disturbance comparable with the happenings in those dimensions, we are unable to measure precisely certain pairs of physical quantities at the same time, e.g. position and amount of motion (momentum). That is, the uncertainty applies to our knowledge about micro particles not to those particles themselves.

However, so many physicists nowadays consider that elementary particles could be ‘here’ and ‘there’ at the same time. Really. Some of them even explain the birth of our universe this way: one poor particle from ‘there’ (other universe) happened to be ‘here’ (our universe). Really?

Oh, how many times did I tell to my fellow physicists that the laws of physics (all natural sciences, for that matter) are not laws of Nature but the laws of our thinking about Nature.
