2.6.2 (b) Using spheres

Chemists have their own convention for representing molecules and their constituent atoms. As in Figure 6, they often use circles (or spheres if they make a three-dimensional model) to represent atoms - and they often use short, straight lines between the circles to represent the bonds that join one atom to anot

Changes in microstructure of a shape memory alloy (CuAlNi single crystal)
Changes in microstructure of a shape memory alloy being heat treated and also mechanically deformed. A CuAlNi single crystal (2H orthorhombic phase ) is compressed (vertical axis) at room temperature, causing activation of two sequential twinning deformations. As austenite, the crystal is cube-shaped, whereas in the martensite form it is sheared. Six different sheared martensite crystals, having well - defined prism shapes (three of which appear in this video), can be created by pressing on 3 di

3.2 Poverty as natural/inevitable

There is a construction of poverty that identifies it as a necessary feature of social life: some people will be better endowed, try harder or be more successful than others, and inequality will be an inevitable result (see, for example, Herrnstein and Murray, 1994, who argue that low levels of intelligence are the main determinants of poverty in the USA). Interfering with this natural order of things is dangerous, particularly because it prevents poverty acting as a spur to try harder. This
