5.1 Standing waves

You learned earlier that when a musician plays a note on an instrument, they supply it with energy that causes the primary vibrator to oscillate at certain specific frequencies. In Section 5 we are going to look at what determines these specific frequencies for some of the primary vibrators found in different instruments.

In Unit TA212_1 Sound for music technology: an introduction, we talk about travelling waves: that is, waves that propagate outwards away from their sourc

7.342 G-Protein Coupled Receptors: Vision and Disease (MIT)
How do we communicate with the outside world? How are our senses of vision, smell, taste and pain controlled at the cellular and molecular levels? What causes medical conditions like allergies, hypertension, depression, obesity and various central nervous system disorders? G-protein coupled receptors (GPCRs) provide a major part of the answer to all of these questions. GPCRs constitute the largest family of cell-surface receptors and in humans are encoded by more than 1,000 genes. GPCRs convert

Learning how to learn
Learning how to learn: a process we all engage in throughout our lives, but no single method of learning guarantees success. This free course, Learning how to learn, aims to make the process of learning much more explicit by inviting you to apply various ideas and activities to your own study as a way of increasing your awareness of your own learning. Most learning has to be an active process and this is particularly true of learning how to learn.Author(s): Creator not set

11.5.5 Chance

Another important source of inventions and scientific discoveries is chance, which is strongly associated with acts of insight. As well as the sort of painstaking work that either precedes an invention or goes into the steady improvement in performance, in the development of most inventions there's a moment when chance plays a part. Often people are looking for one thing but find another – perhaps working on one technology when they stumble on the principles behind another. The skill of the

Winter Lecture Series - 2009: Diet detective: What's on the menu for our coastal marine animals?
Dr McLeod – the 2008 McDiarmid Young Scientist of the year – has a fascination with the slimy and disgusting that has seen her study hagfish in Fiordland and metre-long worms in Antarctica. She looks at the importance of rain forest and sea ice for the diets of these creatures. What if more forests are cut down, or if the sea ice disappears? Armed with these answers, it is becoming possible to predict the challenges ahead for these coastal creatures, and for coastal ecosystems in general. 20

2.8 Polar form

You have seen that the complex number x + iy corresponds to the point (x, y) in the complex plane. This correspondence enables us to give an alternative description of complex numbers, using so-called polar form. This form is particularly useful when we discuss properties related to multiplication and division of complex numbers.

7.2 What people do with the money?

Diane and John didn't get any money.

Enid saved her ‘lads’ money for them, and bought them clothes and other things from what she saved. She spent her ICA on herself, though it didn't sound as if she treated herself to many luxuries.

Sarah's payments went towards the allowances for her volunteer helpers at university. They helped her with making meals, mobility around the campus and getting into town. Sometimes she needed help with personal care, such as washing her hair.

1.4.3 R is for Relevance

Relevance is an important factor to consider when you are evaluating information. It isn’t so much a property of the information itself but of the relationship it has with your question or your ‘information need’. For example,if you are writing an essay about the geography of Chile, a book or website about Chilean political history would not be relevant. So there are a number of ways in which a piece of information may not be relevant to your query:
