A player? What? A CD player? Yes, I have both a hard drive and a CD player. What's your point?

What does that have to do with science?

Let's move back to our original topic. Can you show me that science, as defined by the definition I provided above, has not changed, ever?
For example, the Theory of Gravity. Do you believe that 900 years ago, people understood that two bodies with mass will exert a force on each other?

What the hell? You asked me a question, dingbat. I answered it. Why did you ask me the question?

Carl Sims' Virtual Creatures Paper, Siggraph '94 is an earlier computer validation of the theory of evolution.
Programming a robot (or simulation of a robot) to walk in a real physical environment is hard problem. It's difficult enough to compute the set of parameters used to program the joints of a flexible creature with the right pressures and angles to get a creature to stand up and balance itself, let alone figure out the complex interactions required to define it's gait used run, jump, fly, swim, climb, etc.
Using genetic algorithms, however, Carl Sims was able to completely avoid all that complicated design work, and achieve results far better and faster than if he had set out to directly design the motor characteristics of the creatures himself.
Evolution is not simply random changes as creationists tend to think. It also requires a mechanism for selecting good random mutations over bad ones (the environment), and a memory to store a history of good changes (DNA).
Watch the videos on this website. All of the creatures in the paper not only "evolved" from a "single celled" organism, but they also "learned" to walk on their own, using a computer program that puts models of physical creatures' motor characteristics based on a simplified DNA in a real world physical environment.

You said "yes", but the body of your response indicates that "no" would be appropriate.
Historical fiction are literary works weaving tales of fiction in and around the facts of a historical era to promote the author's desires.
The Bible is one particular example of historical fiction.

Thanks for the silly patents. My husband collects silly patents, I need to make sure he has those.
The one I asked about earlier he says is for a perpetual motion machine, but it's being reviewed.
He says food patents are really hard to do because there are no engineering specialties that are related. A close friend of his did food for years -- she hated it -- as a reward they made her an Administrative Law Judge.
A lot of it has to do with making food different colors. Design patents aren't as hard to get as utility patents.

We're all making bets on how long it takes you to realize that your dialogue with a certain unnamed person is a worthless effort. (I'm betting it won't go on much longer.)

Nah, I enjoy doing this. I realized it was sa fruitless effort from the start, but I needed to kill some time anyway. :)

So the Theory of Gravity has never changed?
What did asking me about my hard drive have to do with anything?
Has the Bible never changed over time, between different translations?

haha, and I thought it was just me. Btw, was it you who posted the link to that old computer program thing that just answers questions with stiled questions back, in regards to our "friend?" (see my post 777 and his post 779) to get what I'm talking about.
thanks.

>> one billion dollars (( every 12 years ))!<<
I don't know how much money the patent office makes but I do know that it is one of the few government offices that makes more money than it spends. When Clinton shut down the government except for non-essential services, my husband still had to go to work every day.

stiled = stilted

Very dumb question to prove my pt ...
did gravity pre exist unknown --- secretly ?
Is gravity even in a relative sense really changing ?
