Philosophy in a nutshell pt 3: Derrida and the text
29 min
In 1967, French philosopher Jacques Derrida wrote "There is nothing outside the text". Or did he? It's a bad translation that's launched a thousand bad interpretations - but it's gone on to become a key element of Derrida's work.

Vaccines – the Covid confusion
While developing new treatments drug companies usually release little useful information on how the clinical trials are progressing. However with the world’s attention on potential vaccines against Covid -19, the usually dull data on the progression of each trial step is subject to huge scrutiny. It doesn’t help to clarify things says epidemiologist Nicole Basta when that data raises questions about the rigour of the trial itself. This seems to be what happened with the latest Astra Zeneca, and Oxford University trial – where the best results were reportedly due to a mistake. The link between locust plagues and extreme weather was demonstrated once again when cyclone Gati hit Somalia – dumping 2 years worth of rain in just a few days. This creates a perfect environment for locusts to breed to plague proportions. And this will be the third time in as many years that cyclones will trigger such an effect says Keith Cressman from the UNFAO. However thanks to the previous recent locust plagues in East Africa the countries most in line for this returning locust storm are better prepared this time. A study of tree rings from Greater Mongolia suggests the region is now drying out rapidly, the past 20 years have been drier than the past thousand says climate scientist Hans Liderholm. This points to potential desertification in coming years. And the death of a scientific icon. The Arecibo observatory, featured in the films ‘Goldeneye’ and ‘Contact’, and responsible for the Nobel Prize winning detection of gravitational waves is facing demolition. Sitting in a crater in the jungles of Puerto Rico this 57 year old radio telescope dish has suffered severe storm damage and is in danger of collapse. Astronomer Anne Virkki, who works at the telescope and science writer Shannon Stirone explain its significance. (Image: Credit: Getty Images) Presenter: Roland Pease Producer: Julian Siddle
