In China, drinking alcohol is often still a vital part of doing business. Science is important in China, which has become the scientific leader in several ways, but science is business of course. At times, alcohol belongs to science here.

The vacuum is emptyRichard Feynman

According to Dick himself, this was his catchiest motto, but eventually he abandoned it for being as wrong as it sounds right.


As discussed in Part 1, analyzing “precognition” discredits everything but the in the eyes of pseudo-skeptic scientism worst: The influence of belief on the quantum probability of finding oneself inside a future world. Pseudo-skeptics warn that the mere mentioning of such lends support to all kinds of nonsense like prayer healing. Well, if you want to ensure that nobody can misquote you in support of nonsense, have fun never saying anything anymore ever. I hold that we should not leave some issues entirely to the kooks.


2) Belief and Experimenter Effect

TED talks declined from ‘must-see-every-single-one’ to less interesting than, even from a science and technology perspective - seen a chicken plugger? Superfast slot cars? Bubble Vortices anybody? So it is worthwhile to point out interesting TED talks whenever one happens to still come along.
Solitons, also called solitary waves, are an intriguing topic. They are waves which behave much like particles, yet not in the sense of the quantum physical particle-wave-duality, but in a purely classical sense: They travel much like particles, meaning they do not change their shape for example, and they even bump against each other and can annihilate with their anti-solitons. On the oceans, solitons can appear as rogue waves (not bore, which is a different phenomenon), and many an ocean faring vessel has succumbed to them. They do not just lift the ship like usual waves. They smash it – again, much like one would expect from a solid particle.


The universe expands. The galaxies, as they depart ever further from one another, are classically and even in Einstein’s special theory of relativity, described as dust particles: The universe as a cloud of dust expanding through space. However, in Einstein’s general theory of relativity, this same expansion is described as the universe itself expanding. There is no locally observable difference between these descriptions whatsoever – at least as far as we know. Classical expansion through space and Einstein’s general relativity describing expansion of space both fit together seamlessly.
