Q&A: What did Charles Darwin prove?
It is often said that Darwin’s theory of natural selection is unproven True? I don’t think that is a very useful question because Darwin’s strength comes not so much from what he proved, but from the near-inescapable conclusions that he led us to. He used every means of informing himself about questions that interested him. He is known for his massive and continuous correspondence, always askin...
متن کاملHADRONIC DECAYS OF THE Q (2980)* The MARK III Collaboration
From a studyof 2.7 million J/I/J decays with the MARK III detector at SPEAR, we determine branching ratios for decays of the Q to q?r+~-, x*KrKs, T+T-T+T-, ?r+r-K+K-, pp, the previously unobserved modes q’?r+x-, I~OK+K-, K*qfg+, K*q*O, and new upper limits on pp, ww, 6~, A2 T, ~T,J and r]KK. When combined, the different measurements of the qc mass yield (2980.2 f 1.6) MeV/c2. In the decays Q + ...

متن کاملA Critical Analysis of the Origin and Nature of Classical Mathematical Economics: Why Classical Economists Did Not Use Mathematics?
The role of mathematics in economic analysis is not yet a settled question. Smith, Ricardo, Mill and other eminent classical economists did not use mathematics in their economic theorizations. We have defined classical mathematical economics as the whole body of literature in mathematical treatment of economics originating mainly from the contributions of Cournot, Jevons and Walras. There are ...
متن کاملWhy did you not use both internal thoracic arteries?
That is the question every cardiologist should ask if the patient he or she has referred for primary surgical coronary revascularization returns from the operating room with a single internal thoracic artery graft. There is a substantial body of evidence demonstrating that the majority of coronary bypass patients benefit more when coronary artery bypass graft (CABG) surgery is performed with bo...
