2 Where does the need arise?

There is a rather obvious question that has to be raised at some point, so we may as well get it over with now: Why do we present ourselves with all these problems? After all, life would be easier without them and we could all go off and do jobs that don't involve them. Do we really need to know everything about the universe? Or to send people into space, at significant cost and human risk? Do we really need to send sound and pictures through space? Do we really need to communicate with peopl

10 How to protect yourself against adware and spyware

Steps you can take to protect yourself against this intrusive software.

  • If a window appears suddenly, close it using the 'X' at the top right of the window.

  • Never use the 'close window' option which is sometimes offered in a pop-up window – you never know what is written in the code 'behind' the button or text.

  • Even clicking on the 'No' option to install can have hidden ramifications so the 'X' is the safest option.

5.3 Neighbourhoods

We know that a polygon X is a surface and so each point x in X has a disc-like or half-disc-like neighbourhood. We shall show that a map f that identifies edges of a polygon to create an object Y automatically creates corresponding disc-like or half-disc-like neighbourhoods of each point y = f(x) of Y.

If x is in the interior of X, there is no difficulty: the point x has a disc-like neighbourhood U

3 Needs and problems

The last section has established that engineering is about satisfying needs. In fact, with so many needs, it's a wonder that not everyone is an engineer! So, now that we have talked about both needs and problems, the logical progression is to examine the relationship between them.

Take the water example as being a fundamental need. We can state it thus:

This village needs a supply of clean water. <

4.3 Indirect use of solar energy

The above examples illustrate the direct harnessing of the sun's radiant energy to produce heat and electricity. But the sun's energy can also be harnessed via other forms of energy that are indirect manifestations of its power. Principally, these are bioenergy and hydropower, already discussed in Section 3 above, together with wind energy and wave power.

Al-90 wt% Cu (bronze)
This is a copper-aluminium bronze containing 10 wt% aluminium. A small amount of iron is often added to act as a grain refiner to improve the mechanical properties. Alloys with more than 8 wt% aluminium solidify as the β phase. Below about 930°C, Widmanstätten α phase precipitates. At the eutectoid temperature (565°C) the remaining β decomposes to a lamellar eutectoid of α and β. Rapid cooling from the high temperature β phase can form martensite instead of Widmanstätten α.
