However, it is often far more instructive to examine the spectrum of light from an object such as a star or galaxy, namely the distribution of light intensity as a function of wavelength.

The spectrum of a light source may be revealed in several ways, all of which involve making light of different wavelengths travel in different dire]]> Telescopes may simply be used to collect the light from an astronomical object in order to measure its position, brightness or spatial distribution.

]]> <![CDATA[5.2 Passive properties]]>Freezing is nearly always harmful to living cells because the tertiary structure of hydrophilic molecules such as proteins is disrupted and the permeability of membranes is drastically altered. The concentration of solutes in the blood of teleost fish is only about half that of seawater so, while seawater freezes at −1.9° C, fish blood would be expected to freeze at −1 to −0.6° C. One way in which fish living in very cold seawater avoid what seems like inevitable disaster is by s]]> Freezing is nearly always harmful to living cells because the tertiary structure of hydrophilic molecules such as proteins is disrupted and the permeability of membranes is drastically altered.

These proteins bind to vesicles and organelles and use energy from ATP to move them along the microtubule or microfilament network. Two families of motor proteins, the kinesins and dyneins, move vesicles along microtubules, and members of the myosin family move them along microfilaments (see Box 1). The myosin family is also important in cell movement.

<![CDATA[1.5 The physics and chemistry of coal formation]]>Coal is a type of sediment made up mainly of lithified plant remains. But how does spongy, rotting plant debris become a hard seam of coal? As discussed earlier, plant material growing in mires dies, and then rots under anoxic conditions to form peat (by the process of humification). With time, the mire becomes covered with layers of sediment, the weight of which squeezes water and gas out of the pore spaces and compacts the vegetation. As subsidence allows deposition of further mireâ€]]> Coal is a type of sediment made up mainly of lithified plant remains. But how does spongy, rotting plant debris become a hard seam of coal?

In mines where this is not so, profit levels will depend on the ability of the mine geologist to predict changes in the seam before they are encountered at the face.

Geological problems fall into two categories — gradual changes and sudden changes. Where a change is gradual, such as a seam thinning or splitting, data from boreholes in advance of the workings, supplemente]]> The most profitable coal mines are those that possess unbroken, horizontal seams of constant thickness and quality.

The advantages of harnessing wind energy are obvious; it is free, clean and widely available (but see later). Although a favoured source of ‘green’ energy, the increasing deployment of wind turbines where they are most efficient, on hilltops and coasts,]]> Wind energy was the fastest growing power source at the start of the 21st century, yet wind-driven mills and pumps, and nautical sails for transport were, along with waterwheels, the first mechanical devices to power industrial production.
