This course offers analysis and practice of various forms of scientific and technical writing, from memos to journal articles, in addition to strategies for conveying technical information to specialist and non-specialist audiences. Comparable to 21W.780 Communicating in Technical Organizations, but methods in this course are designed to deal with special problems of advanced ELS or bilingual students. The goal of the workshop is to develop effective writing skills for academic and professional contexts. Models, materials, topics and assignments vary from term to term.

This is the first of a two-semester subject sequence that provides the foundations for contemporary research in selected areas of atomic and optical physics. Topics covered include the interaction of radiation with atoms: resonance; absorption, stimulated and spontaneous emission; methods of resonance, dressed atom formalism, masers and lasers, cavity quantum electrodynamics; structure of simple atoms, behavior in very strong fields; fundamental tests: time reversal, parity violations, Bell’s inequalities; and experimental methods.

How to teach IELTS: SpeakingThis lesson plan introduces the speaking test and its format. It covers the following exam criteria: pronunciation, lexical resource, grammatical range and accuracy, fluency, and coherence. During this lesson, you will also have the chance to practice speaking exercises with your students. Like the listening test, the speaking test is the same for both academic and general tests.If you want additional lesson plans and support, including teachers’ notes, be sure to register for a free Off2Class account.

6.161 offers an introduction to laboratory optics, optical principles, and optical devices and systems. This course covers a wide range of topics, including: polarization properties of light, reflection and refraction, coherence and interference, Fraunhofer and Fresnel diffraction, holography, imaging and transforming properties of lenses, spatial filtering, two-lens coherent optical processor, optical properties of materials, lasers, electro-optic, acousto-optic and liquid-crystal light modulators, optical detectors, optical waveguides and fiber-optic communication systems. Students engage in extensive oral and written communication exercises. There are 12 engineering design points associated with this subject.

This resource contains demonstrations used to illustrate the theory and applications of lasers and optics. A detailed listing of the topics can be found below.
Lasers today are being used in an ever-increasing number of applications. In fact, there is hardly a field that has not been touched by the laser. Lasers are playing key roles in the home, office, hospital, factory, outdoors, and theater, as well as in the laboratory.
To learn about lasers and related optics, one usually takes a course or two, or acquires the necessary information from books and journal articles. To make this learning more vivid and more exciting, and, one hopes, more understandable, one needs to see some of the basic phenomena involved. To fill this need, Professor Ezekiel has videotaped 48 demonstrations that illustrate most of the fundamental phenomena relating to lasers and physical optics.
By using split-screen inserts and a wide range of video-recording capabilities, it is possible to show real-time effects in lasers and optics with the simultaneous manipulation of the components that cause these effects. In this way, one can see effects in close up that would be difficult, if not impossible, to display in front of an audience or in the classroom.
These video demonstrations are designed for:

The individual student of lasers and optics who wants to observe the various phenomena covered in theoretical treatments in courses, books, and technical papers.
The Instructor in lasers and optics in a company, university, college, or high school who wants to illustrate, in class, many of the fundamental phenomena in optics and lasers.

These videos were produced by the MIT Center for Advanced Engineering Study.

This lecture will discuss common grammar errors and stylistic weaknesses in college students' writing--including problems like run-ons, misplaced and dangling modifiers, and illogical tense shifts--and will suggest ways to revise confusing sentences and paragraphs.  The lecture is offered here in three different formats: video without captions, video with captions, and a full transcript.
