Arithmetic, Population, and Energy Part 3 of 8 Most people do not understand exponential growth, yet the concept is of fundamental importance. Lecture by Dr. Albert A. Bartlett, professor emeritus of Physics at the University of Colorado-Boulder
NASA: Piecing Together the Temperature Puzzle The earth is running a fever and scientists predict it is going to get much worse. Data from NASA satellites can be used to monitor climate change and study the possible causes.

1.5.4 Functions and the function notation In Figure 25, the position x of the car depends on the time t. The graph associates a particular value of x with each value of t over the plotted range. In other circumstances we might know an equation that associates a value of x with each value of t, as in the case of the equation x = At + B that we discussed in Section 3. You can invent countless other ways in which x depends on t: for instance x =
1.7 Demonstration of research skills The ‘key ingredients’ are reflected in demonstrations of various sorts of skills: transferable, generic, project based, discipline based.
2.1 The heart of spectroscopy: dispersing light Telescopes may simply be used to collect the light from an astronomical object in order to measure its position, brightness or spatial distribution. 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

1 Unit overview In this unit we'll be concerned with what type of science forms the basis of science education, and for what purpose. You'll explore these issues by reading the text that follows and by tackling the activities that are included; there are also a number of readings. In the latter part of this unit (Sections 10–14) we'll consider some of the practical problems involved in delivering an effective curriculum in science and look at key questions relevant to all three educational tiers –
7.1 Towards a constitution The European treaties establishing the European Union: create an institutional structure for decision making, and set out the freedoms of the individuals and the limits of the decision-making powers over the citizens. The treaty establishing a constitution for Europe was signed by the member states in October 2004. However, at the time of writing (2005), the process of ratification is in abeyance following the rejecti

Learning outcomes After studying this unit you should be able to: understand the arithmetical properties of the rational and real numbers; understand the definition of a complex number; perform arithmetical operations with complex numbers; represent complex numbers as points in the complex plane; determine the polar form of a complex number; use de Moivre's Theorem to find the nth roots o
Introduction In this unit we look at some different systems of numbers, and the rules for combining numbers in these systems. For each system we consider the question of which elements have additive and/or multiplicative inverses in the system. We look at solving certain equations in the system, such as linear, quadratic and other polynomial equations. In Section 1 we start by revising the notation used for the rational numbers and the real numbers, and we list their arithmetical prop

5.3.3 Torus with 1 hole In our last example, we consider a pentagon with two pairs of edges identified. As we saw in Section 2.3, identification of the edges produces a torus with a hole. In this case there are five vertex-neighbourhoods to fit together, as shown in Author(s):
5.3.2 Klein bottle If x lies on an edge, then each of the two points in [x] has a half-disc-like neighbourhood (see Figure 107). When we identify edges, these neighbourhoods fit together to form disc-like neighbourhoods in the Klein bottle.
