Crossing the boundary - analogue universe, digital worlds

How does the computer's peculiar binary world of digital entities differ from our analogue world of colour, sound, taste and touch? This free course, Crossing the boundary analogue universe, digital worlds, explores the way in which information, in the form of text, still and moving images, and sound can cross the boundary from the analogue universe into a digital world.

Introduction to differentiation free course icon Level

Science, Maths & Technology 

Introduction to differentiation

This free course is an introduction to differentiation. Section 1 looks at gradients of graphs and introduces differentiation from first principles. Section 2 looks at finding derivatives of simple functions. Section 3 introduces rates of change by looking at real life situations. Section 4 looks at using the derivative of a function to deduce useful facts for sketching its graph. Section 5 covers the second derivative test, used to determine the nature of stationary points and ends by looking at rates of change, including the real-life situation, using differentiation to find acceleration.

BSE and vCJD: Their biology and management

The furore surrounding the so-called 'mad cow' diseases is an important and controversial episode of recent years. Although it peaked several years ago, the topic is still of great medical significance, influencing the way the public thinks about and experiences science and scientists. All of which is touched upon in in this free course, BSE and vCJD: their biology and management.

Bayesian statistics free course icon Level

Science, Maths & Technology 

Bayesian statistics

This free course is an introduction to Bayesian statistics. Section 1 discusses several ways of estimating probabilities. Section 2 reviews ideas of conditional probabilities and introduces Bayes’ theorem and its use in updating beliefs about a proposition, when data are observed, or information becomes available. Section 3 introduces the main ideas of the Bayesian inference process. The prior distribution summarises beliefs about the value of a parameter before data are observed. The likelihood function summarises information about a parameter contained in observed data and the posterior distribution represents what is known about a parameter after the data have been observed.

Assessing risk in engineering, work and life free course icon Level

Science, Maths & Technology 

Assessing risk in engineering, work and life

Risk is something that must be taken into account at all times when practising as an engineer. We accept risk as part of everyday life so there is a need to balance the risks of an activity against the benefits that it brings. This free course, Assessing risk in engineering, work and life, investigates how we can manage risks at work, in the home and in the wider community. Risk is tied in with accidents so it is vital to understand how accidents -----, how likely they are to occur and how they can be prevented. These subjects are all covered in this course.
