I think a crude way to paraphrase it would be "knowing the Schrodinger eqn doesn't help you understand turbulence". I understand that you know this (and guess you agree), all I am saying is that I think this is all he's saying (but with biology instead of turbulence...).<br /><br />But perhaps I am misinterpreting the article and it's really claiming that QM breaks down in biological systems.AcLahttps://www.blogger.com/profile/17218667647094961766noreply@blogger.comtag:blogger.com,1999:blog-34480619.post-85535160421134392212010-12-29T19:32:54.271-06:002010-12-29T19:32:54.271-06:00Unfortunately, that doesn't make it any cleare...Unfortunately, that doesn't make it any clearer. If he's referring to emergent phenonmena (which I've covered already in several blog entries), then why would this be restricted biological systems? The whole of condensed matter physics is, in principle, dealing with emergent phenomena.<br /><br />Furthermore, just because we are dealing with a system composing huge number of particles, it still doesn't mean that QM isn't applicable. Again, as in condensed matter, we still use QM to describe such many-body system. So while microscopic laws may not be the same as macroscopic laws, QM have been shown to still applicable in both systems.<br /><br />Zz.ZapperZhttps://www.blogger.com/profile/15861398273820851809noreply@blogger.comtag:blogger.com,1999:blog-34480619.post-63558453443431265892010-12-29T09:23:09.430-06:002010-12-29T09:23:09.430-06:00He probably meant, not "quantum mechanical ef...He probably meant, not "quantum mechanical effects are irrelevant to biology" but rather "knowing the microscopic laws is not the same as knowing the macroscopic laws". <br /><br />His next paragraph seems to support this interpretation, as it starts with "Each science has its own autonomous concepts and laws".AcLahttps://www.blogger.com/profile/17218667647094961766noreply@blogger.com
