Amid the Quiet of Colorado's Great Sand Dunes
The sand dunes at Great Sand Dunes National Park in south-central Colorado are famous for being the tallest in North America - and among the quietest places in the entire country. Conor Knighton takes a listening tour. (03:45)

A young person's life inside and outside school needs to include opportunities that enhance their personal development and the chance to explore activities that extend their interests. You need to be aware of these wider opportunities and to encourage students to participate.

Above all, the information, advice and guidance you offer must be impartial and independent. Your prime purpose is to help the student to progress further along his/her own pathway of lifelong learning.

There are many possible strategies for making more use of visualisation within the mathematics classroom. There are several visualisation activities for you to experiment with in Activity 3. One teacher's approach to incorporating visualisation is given in the following case study and three-part video clip.

An important consequence of the persistent currents that flow in materials with zero resistance is that the magnetic flux that passes through a continuous loop of such a material remains constant. To see how this comes about, consider a ring of metal, enclosing a fixed area A, as shown in Figure 6a. An initial magnetic field Bï»¿0 is applied perpendicular to the plane of the ring when the temperature is above the critical temperature of the material from which the rin

Functional analysis
As taught in 2006-2007 and 2007-2008. Functional analysis begins with a marriage of linear algebra and metric topology. These work together in a highly effective way to elucidate problems arising from differential equations. Solutions are sought in an infinite dimensional space of functions. This module paves the way by establishing the principal theorems (all due in part to the great Polish mathematician Stefan Banach) and exploring their diverse consequences. Topics to be covered will inclu

It's that special day in the week again. People begin to gather, set apart by their passionate convictions and the symbols that bind them together. Some stand by and scoff but the like-minded take strength from each other and stride proudly on, indifferent to those who do not share their commitment. For those caught up since birth (the less sympathetic might say â€˜indoctrinatedâ€™) by their elders' commitment and enthusiasm, this is the climax of their week.

Hitler and the Third Reich
This is a module framework. It can be viewed online or downloaded as a zip file. As taught in Spring Semester 2010. The Third Reich is one of the most notorious, discussed and horrific periods of our age and although it is also very well researched, still raises many questions: How could a man like Hitler gain so much power? How could a whole nation â€˜fallâ€™ for the Nazi ideology? Why the Jews ..? In this module we will aim to deal with these and other questions about the time between 1933

The modulus function provides us with a measure of distance that turns the set of complex numbers into a metric space in much the same way as does the modulus function defined on R. From the point of view of analysis the importance of this is that we can talk of the closeness of two complex numbers. We can then define the limit of a sequence of complex numbers in a way which is almost identical to the definition of the limit of a real sequence. Another analogue of real analysis arises

Let's now consider the dust. Photoexcitation (by absorption of photons) and collisional excitation (by atoms/molecules) occur in the atoms and molecules that constitute the surface of a dust grain. Much of this energy is shared throughout the grain, raising its temperature until thermal radiation from the grain balances the energy absorbed. An alternative fate for an incident photon is to be scattered (Figure 15), a process that is very efficient at certain wavelengths. Figure 20 illustrates

In addition to an increase in firing rate of neurons with differing dynamic ranges, the inclusion of discharges from many fibres whose CFs are different from those of the stimulus may also help to account for the wide dynamic range of the ear. You know from Section 3.3 that in response to a pure tone stimulus the basilar membrane vibrates maximally at a g

1. There is a need for a certain level of daily energy intake to allow the body to maintain its BMR, and to carry out work.

2. Adenosine triphosphate (ATP) is the chemical currency of energy used by the body and is produced from the metabolism of food.

3. The body mass index or BMI indicates whether an adult is a healthy weight for their height.

4. Inadequate nutrition is a huge problem globally. Anorexia nervosa is one examp

Books are a good source of information. The publishing process (where a book is checked by an editor before publishing, and often reviewed by another author) means that books are reliable sources of information, although they may need to be evaluated for bias. A growing number of books can be found online.
