For the first video on the subject of symmetry, a grasshopper definition meant to explain rotational symmetry with the pentagonal dodecahedron. symmetry
My doctoral thesis “Aplicações Didácticas sobre Poliedros para o Ensino da Geometria” (Didactic Applications on Polyhedra for the Teaching of Geometry) is available online in this link. Some of its didactic applications will be included in this website (the ones available are found in this webpage , this one and also this). I will publish […]
The webpage concerning the convex semiregular polyhedra includes tutorials meant to show how to model: the truncated tetrahedron from the regular tetrahedron; the truncated cube from the cube; the truncated octahedron from the regular octahedron; the truncated octahedron from the cube. (more coming soon)
The webpage with tutorials on how to model the cuboctahedron and the icosidodecahedron is finished and may be found in the upper menu or here. Comments and suggestions are always welcomed.
The Conference of the International Society for the Interdisciplinary Study of Symmetry, focusing on “Symmetry, Structure, and Information” is scheduled as a Contributing Event to the IS4SI 2021, the annual Summit of the International Society for the Study of Information (IS4SI). This Summit will be held online between the 12th and the 19th of September, […]
(updated in 09.02.2021) Including all the subjects conceived for this site is an ongoing project that will take quite some time to accomplish, so I will detail below those which I consider to be complete (although any of them may be prone to changing): modelling: the convex semiregular polyhedra (1 tutorial) the convex quasiregular polyhedra […]
há várias páginas e conteúdos do meu site em português que não estão, actualmente, acessíveis. O url veraviana.net direcciona-vos para o site que estou a construir mas, gradualmente, as páginas escritas em português voltarão a estar disponíveis. Consultem por favor esta página para saberem quais. os links para os livros geogebra com as contruções passo-a-passo […]
this website is an ongoing project that will be updated, in the following months (and years), with contents and tutorials mostly concerning polyhedral geometry, a subject of a great personal interest to me, so much that I’ve been devoting myself to its study since 2007. if you have any comments or suggestions to send me, […]
