Anisotropic dielectric permittivity: tetragonal-cubic phase transition in barium titanate
A thin section of barium titanate is viewed between crossed-polars, Initially, the sample is below the transition temperature, and since the domains of the anisotropic tetragonal phase exhibit birefringence, it is brightly coloured when viewed between crossed-polars. When the sample reaches the transition temperature, the isotropic cubic phase forms, which appears black.

SP.269 Passing: Flexibility in Race and Gender (MIT)
This course is primarily a literature seminar. We will use American literature as a lens through which to examine different passing tropes. It will provide an introduction to queer, gender, and critical race theories for science and math majors. We will read such works as Running A Thousand Miles for Freedom, Incognegro, and Focault's A History of Sexuality, to name just a few.

9.14 Brain Structure and its Origins (MIT)
This course covers major CNS structures with emphasis on systems being used as models for experimental studies of development and plasticity. Topics include basic patterns of connections in CNS, embryogenesis, PNS anatomy and development, process outgrowth and synaptogenesis, growth factors and cell survival, spinal and hindbrain anatomy, and development of regional specificity with an introduction to comparative anatomy and CNS evolution. A review of lab techniques (anatomy, tissue culture) is
Kinematics of fluids
This free course examines the basic kinematics of two-dimensional fluid flows. Section 1 introduces the differential equations for pathlines and streamlines. Section 2 introduces a scalar field, called the stream function, which for an incompressible fluid provides an alternative method of modelling the flow and finding the streamlines. Sections 2 and 3 derive the stream functions for several simple two-dimensional flow types (the uniform flow, source, doublet and vortex), and suitable co
9.01 Introduction to Neuroscience (MIT)
This course is an introduction to the mammalian nervous system, with emphasis on the structure and function of the human brain. Topics include the function of nerve cells, sensory systems, control of movement, learning and memory, and diseases of the brain.
12.425 Extrasolar Planets: Physics and Detection Techniques (MIT)
This course covers the basic principles of planet atmospheres and interiors applied to the study of extrasolar planets (exoplanets). We focus on fundamental physical processes related to observable exoplanet properties. We also provide a quantitative overview of detection techniques and an introduction to the feasibility of the search for Earth-like planets, biosignatures and habitable conditions on exoplanets.
Demo of Inertia
See a simple example of inertia in this brief, 31-second video. The video is a demonstration being done by a teacher at the front of the class.
6.071J Introduction to Electronics, Signals, and Measurement (MIT)
The course is designed to provide a practical - hands on - introduction to electronics with a focus on measurement and signals. The prerequisites are courses in differential equations, as well as electricity and magnetism. No prior experience with electronics is necessary. The course will integrate demonstrations and laboratory examples with lectures on the foundations. Throughout the course we will use modern "virtual instruments" as test-beds for understanding electronics. The aim of the cours
Capitalist Vistas: Walt Whitman and Spontaneous Order Democratic Vistas is widely and rightly regarded as the greatest of Walt Whitman's prose works, and in it we fi
2.3 Inverse proportion In Section 2.2 you saw that direct proportion described relationships between two quantities, where as one increased, so did the other. Sometimes as one quantity increases the other decreases instead of increasing. This is called indirect proportion. Team tasks are often an example of this. The tim
2.5 Why intentions? Most of the rest of Grice's paper is dedicated to spelling out a way of identifying the meaning of an individual utterance ‘on an occasion’ with the content of the utterer's intentions (Step One). The hard task he faces is to say what type of intention creates meaning. If someone shouts ‘I saw a film last night’ extremely loudly at their brother with the intention of making this brother fall off his bike, this ‘utterance’ (if that is the right word) does not thereby mean fall o
3.1 Protein diversity Of course, our bodies can't just be made up of squidgy bubbles of phospholipid, or we would collapse in a heap on the floor! Stiffer frameworks, both inside and outside the cells, also exist and help to define shape and add strength. These frameworks are formed largely from structural proteins, a class of polymeric materials that form fibres and filaments to provide mechanical support for cells and tissues. Structural proteins are made inside cells but are often then moved into the spa
Business cultures Why are we studying ‘business cultures’? Culture is a metaphor which can be used to explore the identity of a business. It is about how others see the business, but also how the individuals who work there understand it. Culture offers us a powerful insight into the business and what it is like to work within it.
7.2 Asides An aside is a shorter speech, maybe only a few words, spoken sotto voce to the audience. It is presumed that the other characters on stage cannot hear what is being said, unless the aside is between two characters. Unlike the soliloquy, which largely died out with the decline of poetic drama, the aside is a convention that was widely used until the rise of naturalistic drama early in the twentieth century. Nevertheless, it is still employed in those conventional dramatic genres, pantom
4.001J CityScope: New Orleans (MIT)
Do you want to think about ways to help solve New Orleans' problems? CityScope is a project-based introduction to the contemporary city. "Problem solving in complex (urban) environments" is different than "solving complex problems." As a member of a team, you will learn to assess scenarios for the purpose of formulating social, economic and design strategies to provide humane and sustainable solutions. A visit to New Orleans is planned for spring break 2007.

21W.747-1 Rhetoric (MIT)
This course is an introduction to the theory, the practice, and the implications (both social and ethical) of rhetoric, the art and craft of persuasion. This semester, many of your skills will have the opportunity to be deepened by practice, including your analytical and critical thinking skills, your persuasive writing skills, and your oral presentation skills. In this course you will act as both a rhetor (a person who uses rhetoric) and as a rhetorical critic (one who studies the art of rhetor

Vascular Surgery Patient Success Story: Carl Adams
Last November 2010 Carl Adams was flown to the University of Maryland Medical Center after being diagnosed with an aortic dissection, a potentially life-threatening condition in which a tear causes bleeding in the inner wall of the aorta. After arriving at the Medical Center, Carl went into renal failure. Dr. Robert Crawford performed a thoracic stent graft and renal stents and six months later, Carl was given a clean bill of health. In this video, Carl and his fiance Suzanne Good talk about the
