1.6.3 Don’t jump to conclusions

Time-series graphs are popular with newspapers for suggesting and comparing trends. But showing how a single quantity varies with time is not the same as showing how two quantities vary, and then suggesting a link between them.

4.4 Parabola (e = 1)

A parabola is defined to be the set of points P in the plane whose distances from a fixed point F are equal to their distances from a fixed line d. We obtain a parabola in standard form if

  1. the focus F lies on the x-axis, and has coordinates (a, 0), where a > 0;

  2. the directrix d is the line with equation x = −a.

Thus the origin lies on t

Applying object-oriented analysis to the integration of design and construction
This paper implements an Object Oriented Analysis technique to model information related to design and construction. In a previous study, an approach to integrate design and construction processes based upon information analysis and modelling has been proposed. By breaking down the project's vast information into groups of related information, construction related problems have been identified and then traced back too their relevant design processes. This paper models this process using a relati

3.5 Several calculations and using brackets

Sometimes you may want to make several calculations in succession, and the order in which the calculations are performed may or may not be significant. For example, if you want to add 12 + 7 + 13, it makes no difference which of these two processes you adopt:

add the 12 and 7 first, to give 19, and then the 13, to give 32;

or

add the 7 and 13 first, to give 20, and then add this to 12 to give 32 again.

Why create the EU?

All the member states of the EU have declared a belief in certain fundamental values and aims. Those fundamental values include the securing of lasting peace, unity, equality, freedom, security, solidarity, democracy and the rule of law (Article 6 [1] TEU). Remember that the creation and growth of the EU, like the European Convention on Human Rights, was achieved through the efforts of individuals and states that experienced the horrors and economic aftermath of the Second World War.
