Concepts covered: Addition of Improper and Proper Fractions and also Mixed Numbers.
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

The desert biome is characterized by low precipitation, a high rate of evaporation (seven to fifty times as much as precipitation), and a wide daily range in temperature. The dramatic temperature fluctuations are the result of low humidity, which allows up to 90 percent of solar radiation to penetrate the atmosphere and heat the ground during the day, then for this accumulated heat to be released back into the atmosphere at night. Precipitation in deserts, unlike other biomes, is highly irregula
18.969 Topics in Geometry: Mirror Symmetry (MIT)
This course will focus on various aspects of mirror symmetry. It is aimed at students who already have some basic knowledge in symplectic and complex geometry (18.966, or equivalent). The geometric concepts needed to formulate various mathematical versions of mirror symmetry will be introduced along the way, in variable levels of detail and rigor.
2.3.4 Klein bottle There are two other surfaces that can be obtained by identifying both pairs of opposite edges of a rectangle. In one of these, shown in Figure 31, we first identify the edges AB and A'B', labelled a, in the direction shown by the arrowheads. This gives us a cylinder, as before. We then try to ident

Of Mice and Children: Unraveling the Effects of a Technologized Infancy
Dimitri's passion is developing actionable strategies to optimize the cognitive, emotional, and social development of preschool children. The pursuit of that passion has taken him from the exam room, to the community and most recently to cages of newborn mice. Christakis' laboratory focuses on the effects of early environmental influences on child health and development. He speaks frequently to international audiences of pediatricians, parents, and educators about the impact of early learning

Three essays on bank efficiency
Since commercial banks play important roles in the financial markets, it is important to evaluate whether banks operate efficiently. Moreover, given increased competition from non-bank financial institutions, commercial banks should operate more efficiently than they did previously. Commercial banks might operate more efficiently if they have superior information. If this is true, bank size should not matter to the operation of the bank. Thus, as long as the bank has superior information, it wil
This video gives a brief description of a Stem-and-leaf plot, how to make them and use them to find the median and range.
Relative Frequency Histogram
In this video, an unfinished histogram is pictured. The instructor explains how to complete the histogram and does each step necessary to do so.
Drawing a Histogram
This lesson takes provided data about mass to create a histogram about the data. While the lesson relates to a previous experiment, it still provides good step by step instruction on how to draw a histogram. Graph paper will be needed to follow along and complete the lesson along with the instructor. It is hard at times to see what the instructor is writing because the writing is very small.
In this video (06:08), Mr. Khan explains how to visualize data using a histogram. Mr. Khan uses the computer software (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education.
4.2 Subdivisions In this subsection we formalise the idea of a net by introducing a useful concept called a subdivision of a surface. This is a standard kind of net drawn on a surface, and is defined in terms of vertices, edges and faces. It leads to the idea of the Euler characteristic of the surface. All surfaces obtained from polygons by identifying edges arise from a net (of sorts) consisting of a single polygonal face, together with the edges and vertices that remain aft
