Numbers are often approximated to make them easier to handle, but sometimes it doesnâ€™t help very much to round to the nearest 10 or the nearest 100 if the number is very large. For example, suppose the monthly balance of payments deficit was actually Â£24Â 695Â 481. Rounded to the nearest 10, it's Â£24Â 695Â 480; and to the nearest 100, it's Â£24Â 695Â 500. But Â£24Â 695Â 500 is still a complicated number to deal with in your head. That's why it was rounded to Â£25 000 000 in the newspaper

1. A coordinate system provides a systematic means of specifying the position of a particle. A system in one dimension involves choosing an origin and a positive direction in which values of the position coordinate increase. Values of the position coordinate are positive or negative numbers multiplied by an appropriate unit of length, usually the SI unit of length, the metre (m).

2. The movement of a particle along a line can be described graphically by plotting values of the particle's

How have academics and managers attempted to diagnose these largely hidden aspects of business? One well-known example is provided by Trice and Beyer (1984), who concentrated on the idea of there being symbols within a business. They divided these into, first, high-level symbols, which are the more obvious ones such as company buildings and logos, and, second, low-level symbols. They suggested four categories of low-level symbols: practices, communications, physical forms and a common languag

Virtual Sketching: Instructional Low Resolution Virtual Reality Simulations
This research paper describes the implementation of virtual reality immersive simulation studios in academia, facilitated by the use of the ?Virtual Sketching Method? (VSM). The VSM allows the basic expression of architectural forms and the perceptual experience of interior and exterior spaces. It fosters simulations based on render-less (low resolution) visualization in contrast to other simulation workflows based on render-more (high resolution) visualization techniques. It bridges between

In conclusion, what is Babylonian mathematics about? Although it is not easy to answer this question precisely, because of the difficulties of interpretation such as you saw with Plimpton 322, the overwhelming impression is of the study and use of numbers, and various techniques for solving problems involving numbers. Where the numbers arise fromâ€”whether land measurement, economic questions, idealised geometrical objects (cubes, triangles and so on), or just fairly abstractlyâ€”seems

There is a huge proliferation of neurons in early life. Even whilst that proliferation continues, some cells, e.g. neuroblasts, stop being able to divide. At some later stage the proliferation itself virtually ceases. It follows that cells switch from being able to divide, to being unable to divide, and that they switch at the appropriate time: the process of cell proliferation is controlled. The details of the control of proliferation are not yet understood and are not considered here. But o

This section reveals that â€˜usersâ€™ can include a wide variety of people â€“ not just the final purchasers or consumers of a product. The section also makes the case for strong user representation in the design process.

Of course, it is not only me who uses the various products in my home; other people use them as well, both members of the family and visitors. Sometimes the range of users of a product, and their different needs, can be diverse. And in addition to the obvious or intend

Re:Thinking BIM in the Design Studio - Beyond Tools? Approaching Ways of Thinking
The application of digital design methods and technologies related to BIM and Integrated Practice Delivery are altering the how and what of architectural design. The way contemporary architecture is conceived and made is being transformed through the digital methods, processes and applications used in BIM. How architectural education and the design studio model evolve to reflect, interpret, translate, or challenge the multiplicitous and simultaneously variable modes of contemporary practice pres

While information about frequency and intensity is essential for interpreting sounds in our environment, sound localisation can be of critical importance for survival. For example, if you carelessly cross the street, your localisation of a car's horn may be all that saves you. Our current understanding of the mechanisms underlying sound localisation suggests that we use different techniques for locating sources in the horizontal plane and vertical plane.

Artificial photosynthesis
How can government, industry and business better work together to invest in long-term research to harness solar energy and transform carbon dioxide into energy fuel? In this lecture, Global Chair at the University, Professor Geoffrey Ozin talks about using carbon dioxide as a source of fuel rather than treating it as a waste product and pioneering advances in nano-chemistry.
