Física Experimental: Eletromagnetismo (IST)

Física Experimental: Eletromagnetismo (IST)

Curso assente na obtenção e análise de dados experimentais tendo por base duas experiências de eletromagnetismo realizadas com materiais correntes e com recurso ao e-lab (laboratório remoto). O presente curso consiste numa introdução à Física Experimental onde os participantes poderão explorar a análise de dados e tratamento dos erros experimentais associados a experiências de eletromagnetismo realizadas com materiais correntes e com recurso ao e-lab (laboratório acessível remotamente), bem como técnicas numéricas de ajuste de funções aos modelos teóricos que as descrevem.

Os participantes desenvolverão competências na análise de dados experimentais e na definição de critérios para a aceitação de um modelo teórico proposto na interpretação de uma experiência de eletromagnetismo, face aos dados experimentais obtidos.

No final do curso os(as) participantes estarão aptos(as) a:

  • Utilizar algoritmos numéricos em folhas de cálculo;
  • Analisar e propagar as incertezas das medidas;
  • Controlar experiências remotas;
  • Construir uma experiência simples de óptica;
  • Compreender a relação entre corrente eléctrica e o campo magnético.

No curso serão abordados os seguintes aspetos:

  • Introdução à física experimental e seus conceitos básicos;
  • Ajustes numéricos a dados experimentais;
  • Incertezas nas grandezas derivadas;
  • A relação entre corrente elétrica e campo magnético;
  • Indução magnética;
  • Realização de uma experiência prática: Determinação do índice de refração pelo método de Pfund;
  • Realização de uma experiência remota: Variação do valor do campo magnético criado por uma bobine retangular (módulo e orientação).

The Science of Gastronomy (Coursera)

This course introduces a number of basic scientific principles underpinning the methodology of cooking, food preparation and the enjoyment of food. All topics covered have a strong basis in biology, chemistry, and physics application. Among others, they include the consumption of cooked food, the physiological and evolutionary implication of the senses, geographic and cultural influences on food, and the rationale behind food preparation. We will also discuss issues such as coupling of senses to improve sense stimulation; altering flavor by chemical means; and modification of the coloration to improve the appearance of dishes. Following the video demonstrations of the scientific principles of cooking, you will learn to recognize the key ingredients and their combinations for preparing good healthy food.

The Sun and the Total Eclipse of August 2017 (Coursera)

A total eclipse is one of the most spectacular sights you can ever see! It looks like the end of the world may be at hand. There is a black hole in the sky where the sun should be. Pink flames of solar prominences and long silver streamers of the sun's corona stretch across the sky. It gets cold, and animals do strange things. People scream and shout and cheer, and remember the experience their whole life. But total eclipses are important scientifically as well.

Mechanics: Motion, Forces, Energy and Gravity, from Particles to Planets (Coursera)

Most of the phenomena in the world around you are, at the fundamental level, based on physics, and much of physics is based on mechanics. Mechanics begins by quantifying motion, and then explaining it in terms of forces, energy and momentum. This allows us to analyse the operation of many familiar phenomena around us, but also the mechanics of planets, stars and galaxies.
