9.69 Foundations of Cognition (MIT)
Advances in cognitive science have resolved, clarified, and sometimes complicated some of the great questions of Western philosophy: what is the structure of the world and how do we come to know it; does everyone represent the world the same way; what is the best way for us to act in the world. Specific topics include color, objects, number, categories, similarity, inductive inference, space, time, causality, reasoning, decision-making, morality and consciousness. Readings and discussion include

15.822 Strategic Marketing Measurement (MIT)
Marketing research may be divided into methods that emphasize understanding "the customer" and methods that emphasize understanding "the market." This course (15.822) deals with the market. The companion course (15.821) deals with the customer. The course will teach you how to write, conduct and analyze a marketing research survey. The emphasis will be on discovering market structure and segmentation, but you can pursue other project applications. A major objective of the course is to give you s
Handwriting Lesson: Letter Size and Placement
Children have fun learning size and placement of tall, small, and descending letters with the letter sizes and places activity.
2.1 Understanding the polymer state It was the pioneering scientific work of Hermann Staudinger in the early part of the twentieth century which led to an understanding of the polymer state at an atomic and molecular level. Until then, plastics and rubbers had been developed from naturally occurring substances or discovered during routine synthesis. His research laid the basis for all subsequent discoveries and their commercial development. In essence, he realised that polymers were large molecules built up by the repetition of

Freedom of Expression and Hate Speech: What International Human Rights Law Says [Audio]
Speaker(s): Navi Pillay | In recent years, the world has witnessed a number of incidents involving hate speech at times with wide-ranging and global repercussions. Many governments have put in place measures which not always are in consonance with international human rights law. This lecture recalls the relevant provisions of the International Covenant on Civil and Political Rights and the International Convention on the Elimination of Racial Discrimination and showcases the jurisprudence of the

Multiplying rational expressions is basically two simplifying problems put together. This video clip explains how to multiply rationals by factoring both numerators and denominators and identifying equivalents of one to cancel. Dividing rational expressions is the same as multiplying with one additional step—we take the reciprocal of the second fraction and change the division to multiplication. (1:41)
This video explains how a central angle is an angle where the vertex is on the center of the circle and the endpoints are on the circle. The endpoints on the circle are also the endpoints for the angle's intercepted arc. The angle measure of the central angle is congruent to the measure of the intercepted arc which is an important fact when finding missing arcs or central angles. (2:12)
This video describes how inscribed angles are angles whose vertices are on a circle and that intersect an arc on the circle. The measure of an inscribed angle is half of the measure of the intercepted arc and half the measure of the central angle intersecting the same arc. Inscribed angles that intercept the same arc are congruent. (1:44)
Angles in Semicircles
If an angle is inscribed in a semicircle, it will be half the measure of a semicircle (180 degrees), therefore measuring 90 degrees. This video describes how angles in a semicircle can be used to find missing missing angles and lengths. Pythagorean's theorem can be used to find missing lengths (remember that the diameter is the hypotenuse). Also, the measure of an angle formed by a chord to a tangent is half the intercepted arc.
