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.

Lose Yourself in the Digits - Song
This music video is to the tune of Eminem's "Lose Yourself" and teaches about the concept of Pi. Lyrics are not included on the screen but can be found at www.teachpi.org. The lyrics in the chorus are, "You better lose yourself in the digits of pi. It's a high but you got a thousand more to go. The numbers do not stop or drop into pattern, no. To memorize it would take most of a lifetime." (04:26)

Redefining the Wall: Architecture, Materials and Macroelectronics
As a principle element of architecture, technology has allowed for the wall to become an increasingly dynamic component of the built environment. The traditional connotations and objectives related to the wall are being redefined: static becomes fluid, opaque becomes transparent, barrier becomes filter and boundary becomes borderless. Combining smart materials, intelligent systems, engineering, and art can create a component that does not just support and define but significantly enhances the ar
7.06 Cell Biology (MIT)
This course deals with the biology of cells of higher organisms: The structure, function, and biosynthesis of cellular membranes and organelles; cell growth and oncogenic transformation; transport, receptors, and cell signaling; the cytoskeleton, the extracellular matrix, and cell movements; chromatin structure and RNA synthesis.
Exploraci?n de relaciones entre analog?as y bocetos durante la generaci?n de ideas en dise?o industr
An exploration on the analogy-based idea generation process in industrial design is reported. In particular we try to identify relationships between the sketching process and the analogy building in order to elicit requirements for a supporting software. We use concurrent think aloud protocols to obtain experimental data and an extension of a proved content oriented schema to analyze them. Statistical analysis on segments containing .analogical chains. found relations between analogical and desi

Inequality in America.
While many Americans are working harder for less money and paying more for everyday items like gas and food, the rich are getting richer. Bill Moyers Journal analyzes the growing inequality gap on the ground in los Angeles where recently union workers marched to bring attention to how they are getting squeezed out of the shrinking middle class. Bill Moyers also interviews Steve Fraser, historian and author of Wall Street: America's Dream Palace, about the modern parallels and differences to th
Martin Luther Sparks a Revolution
This three minute video explains the German monk's questioning of Catholic dogma that leads to the Protestant Reformation though his questioning of the values of the Catholic Church and its sale of indulgent behavior. A good biography.
Reformation Series #1- Martin Luther
This video looks at the life of Martin Luther. Video shows pictures and words are written on the screen.
Angles of Parallel Lines - Khan Academy Angles of a transverse line when you intersect parallel lines are discussed in this video. Video discusses parallel lines and what a transverse line is. Video then goes into labeling the angles, such as corresponding angles, opposite angles, alternate interior angles, alternate exterior angles, and supplementary angles. The video shows how to find the measurement of each of the angles using what you know about

h-BN inclusion in a β-Si3N4 grain
The micrograph shows h-BN inclusion (precipitate) in a β-Si3N4 grain (within a silicon nitride particulate-reinforced silicon carbide composite). The occurrence of BN inclusions results from the introduction of colloidal BN into the hot isostatic pressing process. They are formed from B2O3 present as a thin surface film on the BN particles in the barrier layer. B2O3 will be molten during the pressing process and will diffuse rapidly into the powder compact and react with Si3N4 to form BN. Such

Hello! My name is Roxana and I'd like to welcome you to One Minute Romanian from the Radio Lingua Network. In this podcast I'm going to be teaching you the basics of Romanian. The great thing about this language course is that you'll be learning all you need to know in just 60 seconds - or thereabouts! Each one minute language lesson will equip you with just enough Romanian to help you get by in lots of situations, either on holiday, or on a business trip to Romania, or just to impress your Roma
Desert bighorn sheep use a lot of energy to regulate their internal temperature in the desert. During the summer the sheep eat plants and drink water every few days. In the winter, desert plants contain enough water for sheep survival.
Ultrasonic tissue characterization aims at improving the ability of ultrasound to classify benign and malignant masses. The akagami distribution was recently proposed to model the statistics of the envelope of the backscattered echo from tissue. Its parameters demonstrated an ability to discriminate benign and malignant masses in breast tissue. However, there is a need to improve the performance of the parameters to reach clinically acceptable standards and also to eliminate any influence of var
Like transistors in a computer, synapses perform complex computations and connect the brain's non-linear processing elements (neurons) into a functional circuit. Understanding the role of synapses in neuronal computation is essential to understanding how the brain works. In this course students will be introduced to cutting-edge research in the field of synaptic neurophysiology. The course will cover such topics as synapse formation, synaptic function, synaptic plasticity, the roles of synapses
