I personality think that we never gonna achieve state of perfection in science since we, the observer, are the part of nature itself...

however, nature seems to walk in its own accord and creating its own rules....as if it had been programmed from the very beginning...if it does, can science and religion can be one thing??

i don't know if my statement could support creationism, since i, myself, am actually evolutionist but how could the other evolutionists explain the fact about this?

I am looking for a good book that covers many aspects of cardiology; not just the physiology. A level of difficulty of about undergraduate level would be appreciated. I'd rather not have a book that is too "textbook-like"; that is, without the colourful drawings that explain nothing.
Thanks.
