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

Desert Biome
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

1.2 Doctor Faustus

Critics who have studied Marlowe's work have for the most part been inclined to take on trust the picture of him provided by Kyd, Baines, Beard and others, and to read the plays as statements of the author's own radical beliefs. But there is an obvious problem with this approach to Marlowe's work: we simply don't know whether these hostile accounts of his opinions are accurate or, as seems likely, deeply compromised by their writers' own motives and circumstances.

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

8.2 Wet etches: acids and bases

The simplest etches use a liquid solvent that converts the material into a soluble compound or a gas. Unfortunately, most materials used in micro-devices have few soluble compounds, so some very aggressive chemicals are needed to attack them. Here is a list of some of the most commonly used ones:

  • Hydrofluoric acid (chemical formula HF) is used to convert silicon dioxide into water-soluble H2SiF6 (plus some hydrogen and water). It

1.4 Summary of Unit A2

In this unit, you have learned about boxplots and about ways of dealing with data given in tabular form.

A boxplot is a way of presenting certain summary statistics and other characteristics of a data set in graphical form. It gives a quick graphical impression of the location, dispersion and the general pattern of skewness in data set, as well as drawing attention to unusually large or small values. In comparing two or more data sets, it is often useful to draw comparative boxplots (th

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

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.

1.5 Significant figures

Sometimes it doesn’t make sense to round to a specific number of decimal places. If, say, you were calculating the cost of fencing at £10.65 per metre, for a garden boundary, the length of which had been given to you as 185 feet, then you would want to multiply 10.65 × 185 × 0.3048.
