My dad used to love to 'tinker' with things. He was an 'engineer' by occupation, and was always coming up with new inventions. He had patented a number of new gizmos or gadgets for the company where he worked, and he just generally loved to fiddle around with stuff. He even entertained the possibility that he could come up with a perpetual motion machine, and, he actually did try one idea he had, but it didn't work. However, the question remains...is it possible to build a perpetual motion machine?

In Science we can not say it as totally impossible, because many impossibilities have been resolved in many branches of Science. Thanks.

Well...I'm not sure about this one. I know what you're saying, but science has been working on this one for centuries, and can't come up with anything yet. However, I wouldn't say it's never going to happen either, really. It just might not happen anytime soon. Thanks for the post.

Aha! I'm glad for you on that one! Of course, it needs constant "energy" from food, etc. in order to KEEP doing that, so it doesn't quite fit the definition of "perpetual motion", which WikipediA defines as "a condition in which an object continues to move indefinitely without being driven by an external source of energy". May your heart 'perpetually' beat strong! Thanks for your post.
