Bernard Lovell Livres
31 août 1913 – 6 août 2012
Bernard Lovell fut un physicien et radioastronome pionnier dont le travail sur la technologie radar pendant la Seconde Guerre mondiale a jeté les bases de ses recherches spatiales ultérieures et cruciales. Après la guerre, il a fondé l'Observatoire de Jodrell Bank, utilisant des radiotélescopes innovants pour étudier les météores et les rayons cosmiques. Sa fascination pour les grandes questions de l'univers a été mise en évidence dans une série de conférences radiophoniques, abordant des interrogations philosophiques sur la place de l'humanité dans le cosmos. Malgré ses efforts scientifiques, Lovell a conservé une profonde appréciation pour la musique et la nature, reflétant une quête tout au long de sa vie d'harmonie dans la science comme dans la vie personnelle.
August 1939 marked a period of significant change, driven by the looming threat of war and the aggressive actions of Nazi Germany. Young researchers found themselves pivoting to urgent wartime projects, with Bernard Lovell playing a crucial role in the development of radar technology. This account offers a passionate, first-hand perspective on the creation of the Home Sweet Home (H2S) radar systems during World War II, highlighting the scientific culture of wartime Britain. It reveals the personal sacrifices, setbacks, and triumphs of those involved in this vital research. Lovell's journey began in Taffy Bowen's airborne radar group, where he contributed to the groundbreaking application of the 10-centimeter cavity magnetron in airborne radar. The failure of Bomber Command to locate targets in overcast skies led to the establishment of a new group under Lovell's leadership to develop a blind bombing system. The H2S radar system, capable of identifying towns and targets at night or in heavy cloud cover, was first operationally used by the Pathfinder Squadrons during the attack on Hamburg in January 1943. Modified units later had a significant impact on the air war against U-boats. This chronicle vividly captures the atmosphere and challenges of the wartime years as Lovell recounts the H2S radar project.
