The article discusses the experience of VU Geology Museum in popularizing science geology, conducting informal natural education, and educating public. It is claimed that non-formal education cannot replace consistent long-term general schools order to educate members society who are sufficiently enlightened issues geological science. Informal only complements, helps interest, emphasize consoli...

in the logic section of the hikmat al-ishraq (the philosophy of illumination), suhrawardi innovatively makes the three modes (necessity, possibility and impossibility) part of the predicate, thus considering the mode of all propositions to be ‘necessary’. insofar as the modes are also discussed in other topics in logic such as contradiction, conversion and syllogism, this innovation also influe...

The Szpilrajn theorem and its strengthening by Dushnik and Miller belong to the most quoted theorems in many fields of pure and applied mathematics as, for instance, order theory, mathematical logic, computer sciences, mathematical social sciences, mathematical economics, computability theory and fuzzy mathematics. The Szpilrajn theorem states that every partial order can be refined or extended...

We have demonstrated displacementand frequency-noise-free laser interferometry (DFI) by partially implementing a recently proposed optical configuration using bi-directional Mach–Zehnder interferometers (MZIs). This partial implementation, the minimum necessary to be called DFI, has confirmed the essential feature of DFI: the combination of two MZI signals can be carried out in a way that cance...

Quantitative methods and approaches have been playing an increasingly important role in cell biology in recent years. They involve making accurate measurements to test a predefined hypothesis in order to compare experimental data with predictions generated by theoretical models, an approach that has benefited physicists for decades. Building quantitative models in experimental biology not only ...
