Much rhapsodical nonsense has been written about the “Mona Lisa” and her enigmatic smile, and there have been endless speculations as to her character and the meaning of her expression. It is all beside the mark. The truth is that “Mona Lisa’ is a study of modeling. Leonardo da Vinci had discovered that the expression of smiling is much more a matter modeling of the check and of the forms below the eye than of the change in the line of the lips. It interested him to produce a smile wholly by these delicate changes of surface; hence the mysterious expression.

People project their mental process into their handwriting. They subconsciously shape and organize their letters, words and lines in ways that directly reflect their personalities. This explains why no two handwriting are –or even can be- alike; the medium is just too personal. Everyday observation confirms the link between handwriting and personality, at least in an elementary way. Precise people construct their words with care, slowly and exactly; dynamic people dash them off. Flamboyant people boldly cover half a page with a few words and a signature, whose size fittingly reflects their expansive sense of self. Most of us have made such Observations. But it takes a practiced eye to discern the scores of variations and interpret the subtle interplay of forces at work in any given handwriting. In fact in Europe, handwriting analysis known as graphology, now enjoys scientific acceptance and common use.

    (a) neat and slow

The simplest method of welding two pieces of metal together is known as pressure welding. The ends of metal are heated to a white head – for iron, the welding temperature should be about 1300oC- in a flame. At this temperature the metal becomes plastic. The ends are then pressed or hammered together, and the joint is smoothed off. Care must be taken to ensure that the surfaces are thoroughly clean first, for dirt will weaken the weld. Moreover, the heating of iron or steel to a high temperature cause oxidation, and a film of oxide is formed on the heated surfaces. For this reason, a flux is applied to the heated metal. At welding heat, the flux melts, and oxide particles are dissolved in it together with any other impurities which may be present. The metal surfaces are pressed together, and the flux is squeezed out from the centre of the weld. A number of different types of weld may be used, but for fairly thick bars of metals, a vee-shaped weld should normally be employed. It is rather stronger than the ordinary butt weld.

  1. The simplest way of welding two pieces of metal together is
    (a) heating the metal
    (b) holding it in a flame
    (c) coating the metal with plastic
    (d) hammering heated pieces
  2. Unless the surfaces are cleaned first
    (a) the metal will not take white heat
    (b) the resulting weld will be weak
    (c) the joint will be rough
    (d) the metal will be less plastic
  3. When iron is heated to about 1300 degree centigrade
    (a) flames turn from white to blue
    (b) chemical reaction starts
    (c) oxide film is found on its surfaces
    (d) it turns into steel
  4. The flux is used to
    (a) make the metal plastic
    (b) cool the heated metal
    (c) cover up any dirt
    (d) dissolve oxide and other inpurities
  5. For fairly thick bars of metals
    (a) a vee shaped weld should be used
    (b) ordinary butt weld should be used
    (c) a number of different types of weld may be used
    (d) a pressure weld may be used
