Na sua juventude não foi um aluno brilhante, nem sequer manifestava grande interesse pelos estudos, mas os seus pais conseguiram convencê-lo a ingressar na Escola de Belas Artes de Haarlem para estudar arquitetura. Foi lá que conheceu o seu mestre, um professor de Artes Gráficas judeu de origem portuguesa, chamado Jesserum de Mesquita. Com o professor Mesquita, Escher aprendeu muito, conheceu as técnicas de desenho e deixou-se fascinar pela arte da gravura. Este fascínio foi tão forte que levou Mauritus a abandonar a Arquitectura e a seguir as Artes Gráficas. Quando terminou os seus estudos, Escher decide viajar, conhecer o mundo! Passou por Espanha, Itália e fixou-se em Roma, onde se dedicou ao trabalho gráfico. Mais tarde, por razões políticas muda-se para a Suíça, posteriormente para a Bélgica e em 1941 regressa ao seu país natal.<br />Estas passagens por diferentes sítios, por diferentes culturas, inspiraram a mente de Escher, nomeadamente a passagem por Alhambra, em Granada, onde conheceu os azulejos mouros. Este contato com a arte árabe está na base do interesse e da paixão de Escher pela divisão regular do plano em figuras geométricas que se transfiguram, se repetem e refletem, pelas pavimentações. Porém, no preenchimento de superfícies, Escher substituía as figuras abstrato-geométricas, usadas pelos árabes, por figuras concretas, perceptíveis e existentes na natureza, como pássaros, peixes, pessoas, répteis, etc. </div><div align="center"><a href="http://1.bp.blogspot.com/-2ls8cWN3PJU/TyBTmmq0R9I/AAAAAAAADrA/bcfrKR68KbU/s1600/rotacional%2Be%2Bde%2Breflex%25C3%25A3o.jpg"><img style="TEXT-ALIGN: center; MARGIN: 0px auto 10px; WIDTH: 235px; DISPLAY: block; HEIGHT: 320px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5701649050931316690" border="0" alt="" src="http://1.bp.blogspot.com/-2ls8cWN3PJU/TyBTmmq0R9I/AAAAAAAADrA/bcfrKR68KbU/s320/rotacional%2Be%2Bde%2Breflex%25C3%25A3o.jpg" /></a> Simetria de reflexão e simetria de rotação<br /><a href="http://3.bp.blogspot.com/-olqaSV5X7ao/TyBTVwmpV8I/AAAAAAAADq0/Y96J3jVF8ws/s1600/simetriarotacional.jpg"><img style="TEXT-ALIGN: center; MARGIN: 0px auto 10px; WIDTH: 320px; DISPLAY: block; HEIGHT: 311px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5701648761540401090" border="0" alt="" src="http://3.bp.blogspot.com/-olqaSV5X7ao/TyBTVwmpV8I/AAAAAAAADq0/Y96J3jVF8ws/s320/simetriarotacional.jpg" /></a> Simetria rotacional<br /><a href="http://docentes.educacion.navarra.es/~msadaall/geogebra/escher.htm">clica</a> <a href="http://docentes.educacion.navarra.es/~msadaall/geogebra/escher.htm">aqui</a> e explora a simetria noutros trabalhos de Escher.</div><br /><div align="center"></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7139085001567695265-2753682244779959752?l=blogmatematic.blogspot.com' alt='' /></div>Helena Borralhonoreply@blogger.com0tag:blogger.com,1999:blog-7139085001567695265.post-90268066775711464752012-01-25T19:02:00.000Z2012-01-25T19:03:27.705Z<iframe width="460" height="264" src="http://www.youtube.com/embed/6aRFy73cZxY" frameborder="0" allowfullscreen></iframe><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7139085001567695265-9026806677571146475?l=blogmatematic.blogspot.com' alt='' /></div>Helena Borralhonoreply@blogger.com0tag:blogger.com,1999:blog-7139085001567695265.post-40222723006696977092012-01-25T17:36:00.009Z2012-01-25T20:32:56.233Z<div align="justify">Uma figura tem <span style="color:#990000;"><strong>simetria de rotação</strong></span> de centro O e medida de amplitude x se o transformado da figura pela rotação é a própria figura.<img style="TEXT-ALIGN: center; MARGIN: 0px auto 10px; WIDTH: 318px; DISPLAY: block; HEIGHT: 238px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5701626150644707010" border="0" alt="" src="http://2.bp.blogspot.com/-4eUDLoEyCA0/TyA-xodBbsI/AAAAAAAADps/q9I2jYhDapc/s320/quasicristais.png" />Uma <span style="color:#990000;"><strong>rosácea</strong></span> é uma figura com um número finito de simetrias de rotação.

Geralmente parte-se de um pedaço de papel quadrado, cujas faces podem ser de cores ou estampas diferentes, prosseguindo-se sem cortar o papel. Ao contrário da crença popular, o origami tradicional japonês, que é praticado desde o Período Edo (1603-1897), frequentemente foi menos rígido com essas convenções, permitindo até mesmo o corte do papel durante a criação do desenho, ou o uso de outras formas de papel que não a quadrada (rectangular, circular, etc.).<br /><span style="font-size:78%;">(fonte Wikipédia) </span><br /><iframe height="264" src="http://www.youtube.com/embed/qdxbIRkITBk" frameborder="0" width="460"></iframe></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7139085001567695265-2349431866262910264?l=blogmatematic.blogspot.com' alt='' /></div>Helena Borralhonoreply@blogger.com0tag:blogger.com,1999:blog-7139085001567695265.post-19503931863764253822011-10-05T18:54:00.001+01:002011-10-05T18:54:44.822+01:00<iframe width="350" height="267" src="http://www.youtube.com/embed/W4bt6-c2NQk" frameborder="0" allowfullscreen></iframe><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7139085001567695265-1950393186376425382?l=blogmatematic.blogspot.com' alt='' /></div>Helena Borralhonoreply@blogger.com0tag:blogger.com,1999:blog-7139085001567695265.post-25143727701258341172011-10-05T17:45:00.001+01:002011-10-05T17:45:50.522+01:00<div><h3 style="padding: 0px;

Um Kolam é uma espécie de oração pintada - um desenho de linhas composto por curvas, desenhadas sobre uma rede de pontos. Geralmente é simétrico.Em ocasiões especiais, pode também ser feito com pó de calcário e de tijolo para dar contraste aos desenhos. Normalmente é usada farinha de arroz seco mas, para dar maior longevidade ao desenho, por vezes é usada pasta de arroz diluído ou até mesmo tinta. Algumas interpretações modernas já integraram o giz, mas a última "tecnologia" usada para criar kolams é mesmo o autocolante decalcável (que contraria por completo a intenção original).Todas as manhãs, no sul da Índia, milhões de mulheres desenham kolams no chão। Durante o dia, os desenhos são pisados, desfeitos pela chuva ou disseminados pelo vento; no dia seguinte, nasce um novo kolam.<br />Antes do nascer do sol, o chão é limpo com água e bem varrido para que fique nivelado। Os desenhos são geralmente feitos com a superfície ainda húmida, para que o pó agarre melhor. Ocasionalmente, também pode ser <a href="http://1.bp.blogspot.com/-f06NyjG_4fg/Tea3Fdh3lxI/AAAAAAAADbI/hoLNrUizIYQ/s1600/2418214_f496.jpg"><img style="MARGIN: 0px 10px 10px 0px; WIDTH: 252px; FLOAT: left; HEIGHT: 240px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5613375290017814290" border="0" alt="" src="http://1.bp.blogspot.com/-f06NyjG_4fg/Tea3Fdh3lxI/AAAAAAAADbI/hoLNrUizIYQ/s320/2418214_f496.jpg" /></a>usado excremento de vaca para cobrir o chão - a protecção que oferece à casa é literal, dadas as suas propriedades anti-sépticas. Também ajuda a emprestar contraste ao pó branco dos desenhos. Mas o efeito decorativo não era o único objectivo original dos kolams. No passado, eram feitos com farinha de arroz crua, para que as formigas não se tivessem de esforçar tanto por uma boa refeição. O pó de arroz parece atrair aves e outros animais de pequeno porte, trazendo assim outros seres às casas e ao quotidiano dos humanos. <strong><span style="color:#990000;">Os padrões vão do geométrico e matemático criado sobre uma matriz de pontos até às criações artísticas mais livres e às formas fechadas</span></strong>. Conseguir <strong><span style="color:#990000;">desenhar padrões complicados</span></strong> e extensos sem levantar a mão do chão (ou sem nunca desdobrar as costas para ficar de pé) já foi em tempos uma questão de orgulho. O mês de "Margazhi" era esperado com ansiedade pelas raparigas, que mostravam então as suas habilidades cobrindo a largura de uma estrada com um único kolam gigante! Esta era de facto uma prova de mestria, uma vez que o mesmo kolam não pode ser repetido durante 30 dias.Em cerimónias especiais, como casamentos, os padrões rituais do kolam criado para a ocasião podem alongar-se por toda a rua. Os padrões geralmente são passados degeração em geração, de mãe para filha.<br /><iframe height="300" src="http://www.youtube.com/embed/HGwt306KUB8" frameborder="0" width="350"></iframe></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7139085001567695265-6255342710231503951?l=blogmatematic.blogspot.com' alt='' /></div>Helena Borralhonoreply@blogger.com0tag:blogger.com,1999:blog-7139085001567695265.post-14477284117736477672011-06-01T22:23:00.003+01:002011-06-01T22:28:36.387+01:00<div align="center"><a href="http://dmentrard.free.fr/GEOGEBRA/Maths/Algebre/ver324/AtelierGeom.html"><img style="TEXT-ALIGN: center;

Durante o ano de 2009 foi levada a cabo em Madrid com sucesso, a campanha “Mexe-te e Respeita”, que fomentava a mobilidade responsável na cidade. Nesta edição, o Cidadão R regressa para consciencializar a sociedade da importância de valores como o respeito pelo meio ambiente e a utilização responsável da energia. O Cidadão R convida-nos a atuar, adquirindo hábitos e pondo em prática pequenos gestos que ajudam a cuidar do ambiente em que vivemos. </div><br /><div align="justify"><br /><div align="center"><a href="https://2924218575205740723-a-1802744773732722657-s-sites.googlegroups.com/site/lenaprofessoraciencias/Cidad%C3%A3oR-Guiapedag%C3%B3gico.PDF?attachauth=ANoY7criKRDMi8NnMJM8ETTY7Rl4YDj8DQ_fVhN8EfC7ZcPJgDUxuRWMA19y8NfZohPBBHn3-uiZnJVNd6dqOaY7nX7MNU0wWYm-stlpBT3d6k5RCeXXH97WB9NMSDPiKALXxMeas-quUQ8Oxicyjqx7VntWWxA25p8XMXE1ZUEi1m9SVJcHJmP7zqX5DrjW917uQDndOUQwNJo8QY3PCFb6koSUpeF0-7cgFDmntJDnL6aqKviA5Uw%3D&amp;attredirects=0"><img style="TEXT-ALIGN: center; MARGIN: 0px auto 10px; WIDTH: 225px; DISPLAY: block; HEIGHT: 200px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5589899646833109170" border="0" alt="" src="http://3.bp.blogspot.com/-GM9WPyRqf5w/TZNQHLuRqLI/AAAAAAAADYU/ErKoj8JE-fg/s320/CR.JPG" /> Clica na imagem (ou neste link) </a>(lê e realiza as actividades propostas)</div></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7139085001567695265-7234972368549661589?l=blogmatematic.blogspot.com' alt='' /></div>Helena Borralhonoreply@blogger.com0tag:blogger.com,1999:blog-7139085001567695265.post-70939683079173877312011-03-23T12:24:00.002Z2011-03-23T12:28:09.060Z<div align="center"><a href="http://funschool.kaboose.com/fun-blaster/back-to-school/games/game_action_fraction.html"><img style="TEXT-ALIGN: center; MARGIN: 0px auto 10px; WIDTH: 320px; DISPLAY: block; HEIGHT: 202px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5587251026827565794" border="0" alt="" src="http://2.bp.blogspot.com/-_p3BBiXt1SY/TYnnNNT-WuI/AAAAAAAADYM/AEeEHHE_sY0/s320/fra3.jpg" /> clica na imagem<br /></a><br /></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7139085001567695265-7093968307917387731?l=blogmatematic.blogspot.com' alt='' /></div>Helena Borralhonoreply@blogger.com0tag:blogger.com,1999:blog-7139085001567695265.post-76395588356342073542011-03-23T12:08:00.001Z2011-03-23T12:09:27.888Z<div align="center"><a href="http://www.somatematica.com.br/matkids/arqmat.html"><img style="TEXT-ALIGN: center; MARGIN: 0px auto 10px; WIDTH: 320px; DISPLAY: block; HEIGHT: 201px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5587246065444322802" border="0" alt="" src="http://2.bp.blogspot.com/-UgI6elK3oDA/TYnisauB_fI/AAAAAAAADX0/nQSCy3UxHmU/s320/fra2.jpg" /> clica na imagem<br /></a><br /></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7139085001567695265-7639558835634207354?l=blogmatematic.blogspot.com' alt='' /></div>Helena Borralhonoreply@blogger.com0tag:blogger.com,1999:blog-7139085001567695265.post-8589498811511750582011-03-23T12:03:00.003Z2011-03-23T12:11:10.739Z<div align="center"><a href="http://www.harcourtschool.com/activity/fraction_race_a/"><img style="TEXT-ALIGN: center; MARGIN: 0px auto 10px; WIDTH: 320px; DISPLAY: block; HEIGHT: 230px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5587246529577241170" border="0" alt="" src="http://1.bp.blogspot.com/-XuUtPwYjfW0/TYnjHbv8SlI/AAAAAAAADX8/3XkG-H7879o/s320/fra1.jpg" /> Clica na imagem<br /></a><br /></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7139085001567695265-858949881151175058?l=blogmatematic.blogspot.com' alt='' /></div>Helena Borralhonoreply@blogger.com0tag:blogger.com,1999:blog-7139085001567695265.post-28960568546269978122011-03-22T18:20:00.001Z2011-03-22T18:23:47.424Z<div align="center"><a href="http://www.kongregate.com/games/GameScience/refraction"><img style="TEXT-ALIGN: center; MARGIN: 0px auto 10px; WIDTH: 320px; DISPLAY: block; HEIGHT: 212px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5586971127220933666" border="0" alt="" src="http://4.bp.blogspot.com/-0ldOwaaidhI/TYjoo6BeFCI/AAAAAAAADXk/1hH90wCNPwk/s320/re1.JPG" /> clica na imagem<br /></a><div align="justify"><a href="http://3d0ts.files.wordpress.com/2011/02/screenshot001.png"></a><strong>Refraction</strong> é um puzzle que se usa fracções.
