Childrens will research all approximately innovations: their inventors, the way in which they replaced background, and their evolution over centuries, throughout the actions and anecdotes supplied during this interactive sequence. From historical civilization's earliest calendars and shadow clocks to the atomic clocks of this day, the background of time size emerges during this interactive consultant.

Example text
Polyurethane foam will find increased use as the insulation layer in cold-weather apparel and for giving ‘body’ to clothing, whilst other plastics will be widely used for stiffening of light fabrics. The above paragraphs indicate some of the major uses of plastics materials, but these materials also find applications in a variety of other areas. In addition, closely related materials such as rubbers, fibres, surface coatings and adhesives are of considerable importance. 8 THE FUTURE FOR PLASTICS This section was written for the fourth edition published in 1982 at a time when there had just been a further sharp increase in the price of petroleum.
These materials are known as inhibitors and include quinone, hydroquinone and tertiary butylcatechol. These materials are of particular value in preventing the premature polymerisation of monomer whilst in storage, or even during manufacture. It may be noted here that it is frequently possible to polymerise two monomers together so that residues from both monomers occur together in the same polymer chain. In addition polymerisation this normally occurs in a somewhat random fashion and the product is known as a binary copolymer".
These and other materials are widely used where such features as toughness, abrasion resistance, corrosion resistance, non-stick properties, electrical insulation capability and transparency are of importance. In the general area of medicine uses range from spare-part surgery, such as hip joints and heart valves, through catheters, injection syringes and other sterilisable equipment, to more mundane but nevertheless desirable uses such as quietrunning curtain rails. In agriculture and horticulture plastics are most widely known in film form but they also find use for water piping containers, automatic watering equipment and potato chitting trays to name but a few uses.
