La flamme suspendue
La flamme d'un bec de gaz ne traverse pas la grille métallique placée au-dessus ; mais si on allume le gaz au-dessus de la grille, la flamme semble flotter au-dessus de celle-ci, sans contact avec le bec ! Ce phénomène est une conséquence de la bonne conductivité thermique des métaux.
Actionner un moulin grâce à de la chaleur
Un petit moulin réalisé dans une feuille de carton ou de métal très léger se met à tourner dès qu'on allume les bougies placées sous ses pales. On montre ainsi que l'air chaud est plus léger que l'air froid, et s'élève grâce à la poussée d'Archimède créée par la différence des deux densités.
La caléfaction
Si on verse quelques gouttes d'eau au-dessus d'une plaque chauffante, l'eau va-t-elle se vaporiser et disparaître ? Pas sûr…
Température de Curie du fer
Cette expérience un peu délicate à réaliser montre que les propriétés ferromagnétiques du fer (le ferromagnétisme est la propriété pour un métal d'être attiré par le champ magnétique d'un aimant) disparaissent au-delà d'une certaine température appelée "température de Curie".

RES.6-007 Adaptive Antennas and Phased Arrays (MIT)
The 16 lectures in this course cover the topics of adaptive antennas and phased arrays. Both theory and experiments are covered in the lectures. Part one (lectures 1 to 7) covers adaptive antennas. Part two (lectures 8 to 16) covers phased arrays. Parts one and two can be studied independently (in either order). The intended audience for this course is primarily practicing engineers and students in electrical engineering. This course is presented by Dr. Alan J. Fenn, senior staff member at MIT L
RES.18-001 Calculus Online Textbook (MIT)
Published in 1991 by Wellesley-Cambridge Press, the book is a useful resource for educators and self-learners alike. It is well organized, covers single variable and multivariable calculus in depth, and is rich with applications. In addition to the Textbook, there is also an online Instructor's Manual and a student Study Guide. Prof. Strang has also developed a related series of videos, Highlights of Calculus, on the basic ideas of calculus.The 2010 second edition of the Calculus textbook
RES.6-004 Principles of Computer System Design: An Introduction (MIT)
Principles of Computer System Design: An Introduction is published in two parts. Part I, containing chapters 1-6, is a traditional printed textbook published by Morgan Kaufman, an imprint of Elsevier. Part II, containing chapters 7-11, is available here as an open educational resource. This textbook, an introduction to the principles and abstractions used in the design of computer systems, is an outgrowth of notes written for 6.033 Computer System Engineering over a period of 40-plus years.

Des soins dentaires pour tous
Environ 30 % de la population ne bénéficie pas de couverture de soins dentaires. La Faculté de médecine dentaire de l’Université McGill travaille de près avec des organismes communautaires afin de rejoindre ces gens avec sa clinique dentaire mobile.
Organise materials
This topic looks at organising materials for a building project from preparing the materials list (by calculating the required material) through to getting the materials delivered to the site. It also looks at organising plant and equipment.
Fonts for the Web
This project requires the learner to research fonts on the web and font embedding. The learner will have to take into account costs, ligalities, and browser and platform support. The learner is situated in a fictitious company (Arachnoid Web Services) having commenced work as a Junior Web Designer.
Business Requirements for a website
Conduct a business requirements analysis for the Bazaar Ceramics website. This will provide an understanding of what the client expects from the website and what information should be included in the website. Your task is to review the client information provided, interview the client, analyse this information and document your research in a Business Requirements report.
