From a scientist's perspective, to understand everything that you need to know about human beings, you only have to tinker with all the mechanical parts of genes and the brain until there are no more secrets left.
Here I am, a not over-good business man, a second-rate engineer. I can make poor mechanical drawings. I play the piano after a fashion. In fact, I am one of those proverbial Jack-of-all-trades who are usually failures. Why I am not, I can't tell you.
Tinguely wasn't the first artist to work with machines. But others were more interested in precision, in what machines are meant to do. What made him different was the random element. He introduced the mechanical accident. He was always interested in the immaterial, in sound, smoke, speed, light, shadows.
Customers often value a good more when its price goes up. One reason may be its signaling value. An expensive handcrafted mechanical watch may tell time no more accurately than a cheap quartz model; but, because few people can afford one, buying it signals that the owner is rich.
Maths should be more practical and more conceptual, but less mechanical.
Well, guys are better at mechanical stuff and women are better at emotional stuff.
The physiologist who succeeds in penetrating deeper and deeper into the digestive canal becomes convinced that it consists of a number of chemical laboratories equipped with various mechanical devices.
I loved problems on paper, and I was good at math, but I was a mechanical engineer, and I never understood - or cared to - how a car worked.
The mechanical food system externalizes a lot of costs like obesity or Type 2 diabetes.
It frequently happens that two persons, reasoning right on a mechanical subject, think alike and invent the same thing without any communication with each other.
It turns out that if you optimize the performance of a car and of an airplane, they are very far away in terms of mechanical features. So you can make a flying car. But they are not very good planes, and they are not very good cars.
Trying to understand the way nature works involves a most terrible test of human reasoning ability. It involves subtle trickery, beautiful tightropes of logic on which one has to walk in order not to make a mistake in predicting what will happen. The quantum mechanical and the relativity ideas are examples of this.
