The Errors of Statistical Hypotheses and Scientific Theories (Stephen P. Smith)
The process of error recognition is explored first in statistics, and then in science. The Type II error found in statistical hypothesis testing is found analogous to Karl Popper’s “logical probability” that is intended to measure the likelihood that a scientific theory can avoid its refutation. Nevertheless, Popper’s reliance on deductive thinking is found detracting from his demarcation that separates science and metaphysics. An improved critical logic for science is presented that permits error recognition more broadly: for induction by Popper’s falsification principle; but also for deduction and emotionality. The reality of induction creates a limitation for a science that has not accommodated a fuller menu of error recognition. The reality of induction places limits of what can be known from empiricism, and this has philosophical implications. http://prespacetime.com/index.php/pst/article/view/297
Kaluza-Klein Inflationary Universe in General Relativity (by Kishor S. Adhav)
Kaluza-Klein inflationary universe in general relativity has been studied. To obtain the deterministic model of the universe, it has been considered that the energy-momentum tensor of particles almost vanishes in the course of the expansion of the universe and thereby total energy-momentum tensor reduces to vacuum stress tensor. This assumption leads to (i) a ~ exp[Ht], where a is scale factor and H is Hubble constant. (ii) the effective potential V( ϕ) = constant, where ϕ is Higg’s field. It is observed that inflationary scenario is possible in Kaluza-Klein universe. http://prespacetime.com/index.php/pst/article/view/279
10 Reasons to Buy into Big Science (by Philip E. Gibbs)
When people hear the price tag for big science experiments like the Large Hadron Collider or the Hubble Space Telescope they wonder what the benefits are that justify the cost. I am not talking about projects with obvious potential benefits such as a fusion reactor. This is about pure science, why is it worth doing? In fact there are lots of reasons so here is my list of the top 10, starting with the least important.
