It seems S.o.D has no engineering qualifications. That could be a reason that he does not understand the application of measurements, statistics, mathematics, thermodynamics and heat transfer.<br />keep well<br />Cementafriend (not sure how one puts that in Swedish- a double meaning a/ cement or zement or ciment which hardens b/ join or unite )Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1500584444083499721.post-5870348117431887302010-11-22T01:32:42.152+01:002010-11-22T01:32:42.152+01:00A little bit out of topic, but I suggest you all h...A little bit out of topic, but I suggest you all have a look at this paper:<br /><br />http://www.nonlin-processes-geophys.net/14/641/2007/npg-14-641-2007.pdfAndershttps://www.blogger.com/profile/15294862989593516422noreply@blogger.comtag:blogger.com,1999:blog-1500584444083499721.post-38064618904875102272010-11-18T13:18:34.795+01:002010-11-18T13:18:34.795+01:00The problem is not only that they rely on computer...The problem is not only that they rely on computer simulations for validation and predicting the future. The main problem is that their entire physics is wrong. <br /><br />As a matter of fact, today i'm doing experiments with optical pumping. When you read about it in the manual you realise that light is quite remarkable, it carries not only energy, but also momentum, angular momentum and so on. In optical pumping it is actually the conservation of angular momentum that is the key to the entire effect. <br /><br />It is when you contemplate over these conservation laws that you understand where it all went wrong. <br /><br />According to the greenhouse gurus CO2 absorbs IR-radiation and reeimts it isotropically...<br />I don't think so ;)<br /><br />In that case momentum is devoid of meaning....Andershttps://www.blogger.com/profile/15294862989593516422noreply@blogger.comtag:blogger.com,1999:blog-1500584444083499721.post-14510702090726329002010-11-18T00:54:54.470+01:002010-11-18T00:54:54.470+01:00I thought this post was going toward a pithy criti...I thought this post was going toward a pithy criticism of relying on computer models in climate science, rather than relying on good, fundamental physical insight. In my view, today's climate scientists think physical insight comes from exercising their rudimentary models, robotically, with the obvious result that they don't have any good physical insight anymore. They have literally thrown it away, and teach the eager children, and grasping politicans, their empty games as sacred truth. As for the war in mathematics education, I am from an older and I think finer tradition, and nothing speaks more clearly to me of the dull state of current thinking, than the popularization of "maths" for mathematics. With such easy truncation of an ancient word with ancient meaning, they are turning the children into little Eloi (see "The Time Machine", by H. G. Wells), ever so slightly more cut off from past understanding. And a child of 6 or 7 has no use for complex numbers, don't stifle his wonder with the seriousness of even "cool maths", so young. Teach him to draw well, instead -- that will stimulate his appreciation of nature, and the design inherent in it, leading to lifelong observation and insight into it. And all would-be teachers should learn Piaget's theory, and the development in the child of first concrete, and only much later formal, or adult, thinking.Harry Dale Huffmanhttps://www.blogger.com/profile/03210275295826050501noreply@blogger.comtag:blogger.com,1999:blog-1500584444083499721.post-36784274337528498022010-11-17T13:28:50.929+01:002010-11-17T13:28:50.929+01:00Long ago my maths professor said complex numbers s...Long ago my maths professor said complex numbers should be taught in primary school because young children have good imagination. My grandson (just 6) just told me a million has 6 zeros, a billion (US not English) has 9 zeros. I have taught him odd and even numbers, and doubling. Maybe next year I can introduce him to the square root of minus one and vectors and see if the professor was right. The grandson already knows that the sun is a small star and that order of the planets out to Neptune. I think he knows more than most of the so-called climate scientists.<br />keep well<br />cementafriendAnonymousnoreply@blogger.com
