Kern-me

No tempo em eu que roubava folhas de letras de decalcar decadry do meu pai para identificar os meus cadernos, percebi que não era fácil encontrar o espaçamento adequado entre duas letras. Mesmo usando uma régua não conseguia produzir o mesmo resultado da minha percepção da distância certa: o “i” tinha de ficar mais afastado de um “l” do que de um “o”. Só mais tarde, quando comecei a usar o LaTeX para compor documentos, percebi que a isto se chamava kerning e que o que importa manter constante é a área do espaço entre as letras. No caso anterior o “i” e o “l” limitam uma área rectangular mas no caso do “o” é necessário considerar também o espaço por cima e por baixo da parte curva da letra. Não sendo agora comum o uso das letras de decalcar, este jogo de kerning ajuda a perceber a importância da boa composição tipográfica, avaliando a capacidade do jogador em distribuir o espaçamento entre as letras de uma palavra.

A recent Schumpeter column in “The Economist” referred the report “Opportunities for Efficiency and Innovation: A Primer on How to Cut College Costs,” by Vance Fried of Oklahoma State University. Is it possible to provide a first-class undergraduate education for $6,700 a year rather than the $25,900 charged by public research universities or the $51,500 charged by their private peers?

At IST we receive around €3,800 ($5,320) from the government for each student per year and we charge €1,000 ($1,600) for tuition. I believe we provide first-class undergraduate education and research.

Com o ensino superior é diferente?

 Todos os meus filhos foram e irão para a Universidade portuguesa. O ensino superior português é de elevadíssima qualidade. As nossas escolas de engenharia são das melhores do mundo. O Instituto Superior Técnico é uma das melhores escolas de engenharia do mundo. E eu sei, porque temos na Hovione engenheiros vindos das melhores escolas do mundo.

The virus was first detected on June 27, 2010 and the story includes the assassination of Majid Shahriari, a quantum physicist who worked with the Iranian Atomic Energy Commission, on November 29, 2010, when motorcycle riders attached a bomb to his car.
