    I Ching 3D

    No full text
    Knowledge about number bases and random processesThe Book of Changes, also known as I Ching (Yijing), is a traditional oracle from China. It might be the earliest example of simple systems based on binary distinctions. It generates 12 bits that can be interpreted as two pairs of 3D coordinatesComponente Curricular::Educação Superior::Ciências Exatas e da Terra::Matemátic

    Knowledge about Integers, Nested Patterns, Number Bases, Representations of Numbers and Substitution SystemsThe pattern formed by the binary or other digits of successive integers is always ultimately nestedComponente Curricular::Ensino Médio::Matemátic

    Distribution of the last digit of the primes

    No full text
    Knowledge about number theory and prime numbersThis Demonstration shows the distribution of the last significant digit of the prime numbers expressed in any base. You will notice that bases that are themselves prime tend to produce much more even distributions than those that are not. The axis shows the density, that is, the fraction of prime numbers that end in that digitComponente Curricular::Ensino Médio::Matemátic

    Componente Curricular::Ensino Médio::GeografiaAnimação que mostra os processos da criação do Canal do Panamá, desde o motivo (diminuir as distância entre os oceanos Atlântico e Pacífico) ao seu contexto histórico. Esse contexto histórico é complementado com o item "linha do tempo" (canto inferior direito da animação), nesse item o aluno poderá observar o processo histórico pelo qual passou a construção do canal, desde o início de sua construção em 1881 por uma empresa francesa a retomada pelo Panamá em 199

    Gabriel's horn

    Curve y=1/x, infinit, surface of revolution, volume, piGabriel's Horn is obtained by rotating the curve y=(1/x) around the x axis for 1<=x<infinit. Remarkably, the resulting surface of revolution has a finite volume and an infinite surface area. It is interesting to note that as the horn extends to infinit, the volume of the horn approaches piComponente Curricular::Educação Superior::Ciências Exatas e da Terra::Matemátic
