Competition or displacement reactions are used to introduce patterns in reactivity. Demonstrations commonly include the thermite demonstration, and a range of metals with copper(II) oxide. While the thermite reaction provides an unforgettable spectacle, the smoldering beauty of the reaction between zinc metal and copper(II) oxide provides a number of learning opportunities and links with further demonstrations associated with acid-base chemistry, properties of metals, metal extraction and purification. The various stages provide evidence of chemical changes through the strongly exothermic reaction, the release of light energy, the observed colour changes, the change in conductivity of the copper sample, and the production of gas in both the reaction with acid and the electrolysis.

The subject of this course is the historical process by which the meaning of "technology" has been constructed. Although the word itself is traceable to the ancient Greek root teckhne (meaning art), it did not enter the English language until the 17th century, and did not acquire its current meaning until after World War I. The aim of the course, then, is to explore various sectors of industrializing 19th and 20th century Western society and culture with a view to explaining and assessing the emergence of technology as a pivotal word (and concept) in contemporary (especially Anglo-American) thought and expression.

Introduction to microelectromechanical devices (MEMS). Material properties, microfabrication technologies, structural behavior, piezoresistive and capacitive sensing, electrostatic actuation, fluid damping, noise, amplifiers, and feedback systems. Student teams design microsystems (sensors, electronics, and feedback) to meet a set of specifications (sensitivity, frequency response, linearity) using a realistic microfabrication process. Emphasis on modeling and simulation in the design process.

Students investigate circuits and their components by building a basic thermostat. They learn why key parts are necessary for the circuit to function, and alter the circuit to optimize the thermostat temperature range. They also gain an awareness of how electrical engineers design circuits for the countless electronic products in our world.

Chip Kidd doesn’t judge books by their cover, he creates covers that embody the book — and he does it with a wicked sense of humor. In one of the funniest talks from TED2012, he shows the art and deep thought of his cover designs. This talk is from The Design Studio session at TED2012, guest-curated by Chee Pearlman and David Rockwell.

This book was written by two artist educators who teach digital art and design studio foundation classes. While teaching classes that take place in software laboratories, we noticed that many of our students expected to learn to use software, but gave little consideration to aesthetics or art and design history. A typical first day question is, "Are we going to learn Photoshop in this class?" This book is a mash-up of the Bauhaus Basic Course and open source software such as Inkscape, Gimp, Firefox, and Processing. We have taken some of the visual principles and exercises from the Bauhaus Basic Course and adapted them into exercises for these applications.

This course was developed in 1987 by the MIT Center for Advanced Engineering Studies. It was designed as a distance-education course for engineers and scientists in the workplace. Advances in integrated circuit technology have had a major impact on the technical areas to which digital signal processing techniques and hardware are being applied. A thorough understanding of digital signal processing fundamentals and techniques is essential for anyone whose work is concerned with signal processing applications. Digital Signal Processing begins with a discussion of the analysis and representation of discrete-time signal systems, including discrete-time convolution, difference equations, the z-transform, and the discrete-time Fourier transform. Emphasis is placed on the similarities and distinctions between discrete-time. The course proceeds to cover digital network and nonrecursive (finite impulse response) digital filters. Digital Signal Processing concludes with digital filter design and a discussion of the fast Fourier transform algorithm for computation of the discrete Fourier transform.

Aspirations are rising as never before across the world, thanks in large part to smartphones and the internet — will they be met with opportunity or frustration? As President of the World Bank Group, Jim Yong Kim wants to end extreme poverty and boost shared prosperity. He shares how the institution is working to improve the health and financial futures of people in the poorest countries by boosting investment and de-risking development.

Students' understanding of how robotic ultrasonic sensors work is reinforced in a design challenge involving LEGO MINDSTORMS(TM) NXT robots and ultrasonic sensors. Student groups program their robots to move freely without bumping into obstacles (toy LEGO people). They practice and learn programming skills and logic design in parallel. They see how robots take input from ultrasonic sensors and use it to make decisions to move, resulting in behavior similar to the human sense of sight but through the use of sound sensors, more like echolocation. Students design-test-redesign-retest to achieve successful programs. A PowerPoint® presentation and pre/post quizzes are provided.
