He writes: >> Participants: From the naturalists’ camp: chemist Lee Cronin (University of Glasgow, UK). From the skeptics’ camp: chemist James Tour (Rice University, USA). Okay, origin of life research. Like in any other research, there should be no magic: garbage in — garbage out. Between 25:00 and 26:00 Lee said something like this: We Read More…

L&FP40: Language is . . . (as a foundation for understanding machine code and mathematical language as just that, linguistic)
It seems we need to clarify language. For, we see in the Ortho types thread: EG, 140: >> . . . Definitions of language: Webster’s: the words, their pronunciation, and the methods of combining them used and understood by a community.

Logic & First Principles, 3: The roots of right reason and the power/limits of entailment
Why is this topic important? (Why a series, now on no 3 (see 1 and 2)?) Here at UD, the phrase “first principles of right reason” and similar ones (e.g. “reason’s rules”) have often come up. Others talk about “the laws of thought,” which in a post-Kant world hints of “the ugly gulch” between the Read More…

The origin of life, some researchers believe, must have been simpler.In an attempt to close the gap between Read More…
GP on the Origin of Body Plans [OoBP] challenge
. . . here (at 194) in his amazing engineering thread as he responds to Dionisio: >>Dionisio: Thank you for summarizing that interesting discussion. I will summarize it even more. 1) Nobody knows how morphogenesis is controlled and guided. 2) Moran is no exception to that. 3) “Experts” are no exception to that. 4) However, Read More…
UD Guest Post: Dr Eugen S on the second law of thermodynamics (plus . . . ) vs. “evolution”
Our Physicist and Computer Scientist from Russia — and each element of that balance is very relevant — is back, with more. MOAR, in fact. This time, he tackles the “terror-fitted depths” of thermodynamics and biosemiotics. (NB: Those needing a backgrounder may find an old UD post here and a more recent one here, helpful.) Read More…
