Bernard Lovell Knihy
31. august 1913 – 6. august 2012
Bernard Lovell bol priekopnícky fyzik a rádioastronóm, ktorého práca v oblasti radarových technológií počas druhej svetovej vojny položila základy pre jeho neskorší kľúčový výskum vesmíru. Po vojne založil observatórium Jodrell Bank, kde s využitím inovatívnych rádioteleskopov skúmal meteoroidy a kozmické žiarenie. Jeho záujem o univerzálne otázky vesmíru sa prejavil v sérii rozhlasových prednášok, ktoré zasahovali do filozofických úvah o našom mieste vo vesmíre. Napriek svojej vedeckej kariére si Lovell uchoval lásku k hudbe a prírode, čo odráža jeho celoživotný záujem o harmóniu vo vede aj v osobnom živote.
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.
