Nanotechnology is my own field of research for 12 years now. It is one of the, if not the most important of the emerging technologies, and it is widely believed to be the vital ingredient to many by transhumanists desired transformations, be it slowing down aging, computer to brain network-neuron interfaces, or the development of ever faster (quantum) computers. Nano is still the big buzz word and I am afraid to have become the uninvited party-pooper.

Remember the neat little experiment whose result may be counter intuitive to some of those who embrace the “all bodies fall the same way inside earth’s gravity” ‘doctrine’ without quite understanding it? Here it is again - if the video should not come up fast enough, here it is on the MIT website.

I am acutely aware of my advantages as a tall, white, semi-able-bodied Westerner with middle class background in a northern European culture. I had and still have it much easier than most people especially here in China. Believe me, I am 100% fully aware of how unfair life is, of how much I should not take for granted, and especially of how easy I could have had it, if I had played the usual game with the cards I was dealt. Without my unfair edge, I would not even have been able to dare play my own game.

The following is a neat little experiment whose result may be counterintuitive to some of those who embrace the “all bodies fall the same way inside earth’s gravity” ‘doctrine’ without quite understanding it.

Legal highs: the dark side of medicinal chemistry”, by David Nichols of Purdue University’s pharmacology department, has hardly been published in the prestigious science journal Nature [469, 7 (2011)] and it is already fully exploited for the usual drug war scare tactics bringing anything to do with psychoactive compounds into relation with pure evil - ‘reefer madness’ over and over again [I found some on Yahoo ‘science news’ but I am not going to link to such crap].

How does an electrical torch or flashlight work? According to the usual description, the lamp inside produces light, this light is shone on the objects we desire to see, partially reflected from their surfaces, and finally some of that light is captured by our eyes. This is not wrong, but it somewhat distorts the fundamentals of visual perception, which is not about perceiving light but about perceiving differences.

Actually, all the objects around us send out light all the time, even if the room appears completely dark to us. This light happens to be mostly infrared light. Nevertheless, if seeing was just about detecting light from objects, evolution would have formed us to be able to receive that infrared light.
