<p>294 pupils aged 8-9 years were given subtraction problems. Initially the pupils managed to solve the exercises using the usual algorithm (a-b=c). Simultaneously they made a representation of their solutions using 4 shapes which had been pre-agreed by the pupils and their teacher. Not only were the results unsatisfactorily worked out, but they were lower than the (also) unsatisfactory solutions given in the students’ efforts to solve the problems in the classical way. A teaching configuration was then prepared. After this an overall improvement was discerned in the majority of pupils, in subtraction problems.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0852/a.php" alt="Hit counter" /></p>

Global Monopoles

In the search of avatars of new physics, we present a new classical solution for electromagnetic monopoles induced by global gravitational monopoles in the presence of a four-dimensional Kalb-Ramond axion field. The torsion induces the magnetic charge of the monopole.

We connect the exercisability randomized American option to the penalty method by showing that the randomized American option valueuis the uniqueclassicalsolution to the Cauchy problem corresponding to thecanonicalpenalty problem for American options. We also establish a uniform bound forAu, whereAis the infinitesimal generator of a geometric Brownian motion.

Bhk Semantics

After introducing semantic anti-realism and the paradox of knowability, the paper offers a reconstruction of the anti-realist argument from the theory of understanding. The proposed reconstruction validates an unrestricted principle to the effect that truth requires the existence of a certain kind of “demonstration”. The paper shows that the principle fails to imply the problematic instances of the original unrestricted knowability principle but that the overall view still has unrestricted epistemic consequences. Appealing precisely to the paradox of knowability, the paper also argues, against BHK semantics, for the non-constructive character of the demonstrations envisaged by anti-realists, and contends that, in such a setting, one of the most natural arguments in favour of a revision of classical logic loses all its force.
