No we do not. And you can be assured that behind the above method there are some very big brained people solving the everyday details of manufacturing. We do have mathematical models that try and get close to reality. But behind all the models are creative, problemsolving, intuitive, risk-taking, curious, analyzing dreaming, humans.lucaspa said:Don't you use genetic algorithms in your part of the aerospace industry?
Things are not so simple that all we need to do is apply Darwinin selection and then no problem is too tough. I have a >20GHz (K band) RF chain that needs to fit in a 1" X 1" X 4", box. I need 5dBm output power over -20C to 70C. And I have very tight (< 50dBc) spur specs. The power can only vary 1dB over all conditions over the entire 10+ year lifespan in a very harsh high radiation environment. We will thermal cycle this thing for weeks, we will shake it and bake it, We will freeze it under a vacuum, spray it with RF. There is a list of specifications that goes on for several pages. And we want to make a buck. This is not a profit free zone.lucaspa said:Right, which is why human engineers use Darwinian selection when the design problem is too tough for them.
Armies of engineers and business weenies are looking for a better way. If you really had a better way than you would not be here talking to us. Your time would be priceless as you solve all the worlds engineering problems.
Some starting point! Two big brained scientists with a purpose and the highest data density structure in the known universe. Nature has no purpose, it does not know where it is going, and can't select for unknown future goals. All the examples you cite require humans with a specific purpose.lucaspa said:Here's some more examples:
1. Nature doesn't make DNA sequences that are also enzymes. So we have no idea even where to start in designing a DNA enzyme. But Joyce and co-workers simply started out with random DNA sequences, tested them for any enzymatic activity, kept those that did, and then introduced random changes in the sequence each generation. Each generation the sequences were tested against the environment of enzymatic activity. Now there is a whole family of DNA enzymes, some of which will be used on patients.
And I am proud to be incredibly ignorant.lucaspa said:So, all in all your argument comes down to:
1. Personal incredulity.
2. Ignorance of what is happening in your field of engineering.
Peace.
