Many scientists spend much of their time writing, debugging, and maintaining software. But while techniques for doing this efficiently have been developed, only few scientists actually use them. As a result, they spend far too much time writing deficient code and reinventing the wheel instead of doing research. In this course we present a selection of advanced programming techniques with theoretical lectures and practical (more…)

What is Python? Python plays a key role in our production pipeline. Without it a project the size of Star Wars: Episode II would have been very difficult to pull off. From crowd rendering to batch processing to compositing, Python binds all things together. Tommy Burnette, Senior Technical Director, Industrial Light &Magic. Conditionals If-statements: ifx<0: print”negative” elifx==0: print”zero” else print”positive” Logic-ops: (more…)

The University of Oxford’s Physics department is one of the largest Physics departments in the United Kingdom. Each October it admits around two-hundred students to study for either the 3-Year BA or the 4-Year MPhys. Both groups of students follow the same course until late in the third year. The students are perhaps amongst the most able produced by British and international schools. Typical entrance requirements are three ‘A’ grades at A Level, which must include Mathematics (more…)
