I always get leery when mentioning this, but the things that can be done with a $4.00 microcontroller these days are frightening. I was cringing during the Iraq war that we would start to see autonomous M-50 machine guns on rooftops that could target the whup-whup of helicopters. Something like...
Requirements:
Between .5cm and 1cm large.
It must negotiate 3-D space in an air atmosphere.
It must be capable of autonomous existence.
It must be capable of high-g acceleration to rapidly start and stop.
It must be able to remain stationary on a surface at any spatial orientation.
It...
It's not that, I understand things are pressured in certain directions.
I'm saying that things like migration paths are more than just learned by following, they are in the genes. If these complex behaviors are selected for, then so be it; but I wonder if there might not be additional help...
There should be fines for publishing drivel like that article.
The first clue that it was B.S. was the fact that they never really said what they succeeded in doing. What does 'successfully search a database' mean?
Ultimately, I'm certain it means nothing, because if they had truly...
DNA computing is just a curiosity. It suffers from a fundamental problem, and that is of gain. Conventional transistors have gain, which allows the signal to be lifted out of the noise.
No such luck with DNA. They are probably using a roomfull of equipment to read the DNA.
I always bind my controls to a class member. If I declared a CButton member object in my dialog named m_MyRadio, then:
m_MyRadio.GetCheck ();
will do the trick.
Chance is a totally valid strategy.
There are caves where the entire population of species shows signs of once having eyes.
How could they all lose their eyes?
It's actually a remarkable demonstration of the wringing out efficiency by selection. Since eyes are useless in a cave, they...
Even if a salmon does employ some kind of marker or sense, it still requires a very sophisticated set of behaviors.
Wiki says that salmon spend as much as 5 years in the open ocean, but it does not say how far they range there, only that they may travel hundreds of miles to get back to their...
Logic says that instincts must be selected for over time, but some instincts are so complex that it's hard to stomach as a purely random manifestation.
I also have never heard of a frog that tried to fly south for the winter, and you would thing that as a random process... I don't know...
I get no satisfaction from this answer. That is worded clumsy, but I hope you know what I mean.
I can accept the learning explanation, but instinct by definition is not learned. Many are not even consciously engaged.
I can even buy the bird-folllowing-bird scenario to some degree, but even...
If you walk into a bar and see a que ball at rest on a pool table, what indications do you have on how it arrived at that state?
