Inscribed Angles
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.

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

Winter in a temperate region poses a number of environmental problems for organisms. Most obviously, average temperatures are lower than at other times of year and there are frequent frosts. Frost is highly significant for living organisms because water forms such a large proportion of their body tissues; for the great majority of organisms, freezing of their tissues leads to death. Secondly, because, as shown in Table 1.1, many adult organisms die, go into hiding or migrate in winter, many o

Searching for Syphilis
At the end of the 15th century a terrifying new epidemic spread across Europe, but was this disease, known as the Great Pox, really Syphilis? Did Christopher Columbus actually bring the disease back from the New World? Join us as we look at whether the discovery of a 600 year old skeleton can shed new light on the origins of one of mankind's most enduring diseases, which still affects 12 million people every year. This material forms part of The Open University course S320 Infectious disease.

Several TSEs of non-human animals were also known before the recognition of BSE and others have come to light subsequently. The most significant of the former is scrapie, a disease of sheep that has been known for over 200 years. Its symptoms include irritability, excitability, restlessness, scratching, biting, rubbing of the skin (hence its name), loss of wool, weight loss, weakness of the hindquarters and sometimes impaired vision. Some breeds are relatively resistant to the disease (e.g. S
