Introduction to polymers

...law (Equation (27)), HIPS yields and necks before failing. By contrast, rubbers exhibit long-range elasticity and fail only at many hundred per cent strain. [Figure 44] Figure 44 Tensile stress-strain curves for some rubbers and plastics So some plastics like HIPS yield, but others fracture in a brittle manner like polystyrene. Rubbers do not yield, but at high strains...

Project management: the start of the project journey

...law. For example, in a computer system there will be frequent but minor failures in disk accesses: these failures are normally overcome simply by retrying the access. Far more rarely, a disk’s read head will touch the delicate magnetic surface, and then the disk is effectively destroyed and access is impossible under any circumstances. The former occurs frequently but...

...law. This would include fraud for personal gain; such as the Ponzi scheme run by Bernard Madoff that cheated investers out of billions of dollars by lying about investment returns, or fraud to cover up mistakes - rather than for personal gain - as with the case of Nick Leeson, whose actions brought down Barings Bank in 1995. A similar, and more recent, example came in...

Describing language

...law; not all bits of language necessarily obey them. Some grammar rules are more like observations or generalisations that are true in very many cases but not all. It's like saying birds are warm-blooded creatures that have two wings and can fly. There are obvious exceptions: ostriches, penguins, and emus for a start. There are, in fact, quite a lot of flightless birds,...

...laws, so that while the satellite’s spin continues at a uniform rate, its speed round an elliptical orbit will vary. Well, let’s begin by dividing a single orbit into four. Each position is reached after a quarter of the orbital period. The satellite travels fastest when closest to the planet, in accordance with Kepler’s second law. Now, the satellite must be...
