Science, Maths & Technology
Basic science: understanding experiments
This free course, Basic science: understanding experiments, introduces you to science-based skills through simple and exciting physics, chemistry and biology experiments.

Science, Maths & Technology
Introduction to linear equations and matrices
In this free course, matrices are used as a concise way of representing systems of linear equations which occur frequently in mathematics. Section 1 looks at simultaneous linear equations in two and three unknowns and then generalises the ideas to systems of linear equations. Section 2 develops a strategy for solving systems of linear equations....

Protocols in multi-service networks
The internet, like the telephone system which preceded it, depends for its existence on communications networks. This free course, Protocols in multi-service networks, examines these networks as the means of interconnecting devices so that two-way communication is possible. Examining protocols like HTTP, TCP/IP and ATM as well as the OSI ...

Univariate continuous distribution theory
This free course looks at a number of the basic properties of statistical models. Section 1 is concerned with the distributions of continuous random variables which are described by their probability density functions (pdfs) and cumulative distribution functions (cdfs). Section 2 is concerned with moments and covers, the concept of expectation ...

Science, Maths & Technology
The making of individual differences
How do we become individuals? This free course, The making of individual differences, looks at how genes and the environment interact making each of us unique. Looking at the period between conception and birth you will examine the issues of nature or nurture to see which has the greatest impact.

Everyday maths 2 (Wales)
This free course, Everyday maths 2 (Wales), will build on your existing maths skills and help you to feel more confident tackling the maths you come across in everyday situations.

Science, Maths & Technology
Astronomy with an online telescope
This free course shows you how to navigate the night sky, and introduces the wide variety of objects it contains. You will develop a hands-on understanding of telescopic observations using the Open University’s own robotic telescope facility COAST sited on the island of Tenerife. Supported by your own measurements we illustrate how stars...

Science, Maths & Technology
Modelling events in time
This free course develops ideas about probability and random processes. Sections 1 and 2 introduce the fundamental ideas of random processes through a series of examples. Section 3 describes a model that is appropriate for events occurring ‘at random’ in such a way that their rate of occurrence remains constant. Section 4 derives the main ...

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 ...

Science, Maths & Technology
The science of alcohol
Alcohol plays a considerable part in the daily lives of humanity and has done for thousands of years. This free course, The science of alcohol, looks at the science behind the processes of brewing, distilling and vinification, and how many of our beverages are made. A historical aspect is also covered showing how the modern production techniques...

Managing complexity: A systems approach – introduction
Do you need to change the way you think when faced with a complex situation? This free course, Managing complexity: A systems approach introduction, examines how systemic thinking and practice enables you to cope with the connections between things, events and ideas. By taking a broader perspective complexity becomes manageable and it is easier...

Science, Maths & Technology
Distributed paradigms
This free course, Distributed paradigms, looks at some of the architectural and programming paradigms used in distributed system development. You will learn about synchronous and asynchronous message passing, distributed objects technology and event-based bus architecture, before finally moving on to tuple architecture.
