...free course, The formation of exoplanets, you will learn about the challenges connected with efforts to reconcile the observed exoplanet population with current theories on how planets form. The two main theories for this, namely the core-accretion scenario and the disc-instability scenario, will be explored mathematically...Over the last few decades astronomers have...

...free course, Working with charts, graphs and tables, will help you to develop the skills you need to do this. For further study, there's another course titled 'More working with charts, graphs and tables' which looks into more ways to present statistical information and shows you how to use charts, graphs and tables to present your own information...When you come across...

...free course, Interpreting data: Boxplots and tables, is concerned with two main topics. In Section 1, you will learn about another kind of graphical display, the boxplot. A boxplot is a fairly simple graphic, which displays certain summary statistics of a set of data. Boxplots are particularly useful for assessing quickly the location, dispersion, and symmetry or skewness...

...free course explores how information is gathered, stored and shared through technology. Learn about the evolution of IT in news reporting, compare different media sources, and develop a critical eye for trust and authenticity in the information you consume...BBC News 24, Sky News, CNN. We live in an era where news has become almost instantaneous. This free course, IT:...

...free course is concerned with second-order differential equations. Section 1 introduces some basic principles and terminology. Sections 2 and 3 give methods for finding the general solutions to one broad class of differential equations, that is, linear constant-coefficient second-order differential equations. Section 2 covers homogeneous equations and Section 3 covers...

...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. Section 3 looks at the algebra of...
