Science Quotes by David Keith Chalmers MacDonald (1 quote)
It does appear that on the whole a physicist tries to reduce his theory at all times to as few parameters as possible and is inclined to feel that a theory is a respectable one, though by no means necessarily correct, if in principle it does offer reasonably specific means for its possible refutation. Moreover the physicist will generally arouse the irritation amongst fellow physicists if he is not prepared to abandon his theory when it clashes with subsequent experiments. On the other hand it would appear that the chemist regards theoriesor perhaps better his theories (!) as far less sacrosanct, and perhaps in extreme cases is prepared to modify them continually as each bit of new experimental evidence comes in.
