There is a lot now being talked and written about the success of Apollo 11, and the Apollo space programme, half a century ago. The BBC podcast 13 minutes to the moon is fantastic. It tells well the story leading up to and during the 13 minutes that Neil Armstrong and Buzz Aldrin descended to … Read More

[avatar user=”duncansteel” size=”thumbnail” align=”right” /] The name of Michael Faraday is well-known in science, for his pioneering work in both chemistry and physics (in particular electricity and magnetism; hence the name of the SI unit of capacitance, the farad). As a postgraduate student at the University of Canterbury I spent many hours working on experimental radio receivers sat … Read More

[avatar user=”duncansteel” size=”thumbnail” align=”right” /] The Islamic fast of Ramadan has come to an end, marking the beginning of the tenth month of the religion’s twelve-lunation year and therefore Eid al-Fidr, the ‘Festival of Breaking the Fast’.

Ian Crawford, UCL The search for life elsewhere in the universe is one of the most compelling aspects of modern science. Given its scientific importance, significant resources are devoted to this young science of astrobiology, ranging from rovers on Mars to telescopic observations of planets orbiting other stars. The holy grail of all this activity would be … Read More
