The present research has as its main goal to assess the development of positive attitudes and self-reliance toward Mathematics, in students from elementary school I, 4th and 5th grades, with the use of non-structured problems. This research has a quali-quantitative status which owns a northern axis facing data collection, comprehension of behavior,...

The confirmation of excess in $R_{D^*}$ at the LHCb is an indication of lepton flavor non-universality. Various different new physics operators and their coupling strengths, which provide a good fit to $R_D$, $R_{D^*}$ and $q^2$ spectra, were identfied previously. In this work, we try to find angular observables in $\bar{B} \to D^* \tau \bar{\nu}$ ...
The recent measurement of $R_{K^*}$ is yet another hint of new physics (NP), and supports the idea that it is present in $b\to s\mu^+\mu^-$ decays. We perform a combined model-independent and model-dependent analysis in order to deduce properties of this NP. Like others, we find that the NP must obey one of two scenarios: (I) $C_9^{\mu\mu}({\rm NP}...
At present, there are several measurements of $B$ decays that exhibit discrepancies with the predictions of the SM, and suggest the presence of new physics (NP) in $b \to s \mu^+ \mu^-$ transitions. Many NP models have been proposed as explanations. These involve the tree-level exchange of a leptoquark (LQ) or a flavor-changing $Z'$ boson. In this ...

Solving numeric, logic and language puzzles and paradoxes is common within a wide community of high school and university students, fact witnessed by the increasing number of books published by mathematicians such as Martin Gardner (popular books as old as Gardner in Aha! insight. W. H. Freeman & Co., London, 1978, Wheels, life and other mathematic...
This article brings out traces of an important discussion in the context of the philosophy of Nicholas of Cusa, i.e. the discussion about the concept of transsumptio and the use of puzzles as a way out for a discourse on the first principle, that is, God. The objective is to show how this enigmatic or symbolic perspective appears in the Cusan philo...
Knowledge about Plane Geometry and Puzzles / A square is cut into four pieces that can be rearranged to form an equilateral triangle. Henry Dudeney published this puzzle in 1902 / Componente Curricular::Ensino Fundamental::Séries Finais::Matemática
Knowledge about optical illusions, plane geometry and puzzles / Consider the eight orange triangles, four brown pieces, and four squares assembled into the large square shown. By using the slider you can reassemble them into the same large square, but with the middle square missing. Where has it gone? / Componente Curricular::Ensino Fundamental::Sé...
Parametric Equations and Analytic Geometry / Most conventional heart shapes can be constructed, as here, from three circular arcs reflected about the vertical. With this simple parameterization, you can explore a wide variety of hearts, including some unexpected surprises, such as hearts within hearts / Componente Curricular::Educação Superior::Ciê...
