    Science Quotes by Sir Hermann Bondi (21 quotes)


    [Science doesn’t deal with facts; indeed] fact is an emotion-loaded word for which there is little place in scientific debate.

    — Sir Hermann Bondi

    Talk on BBC Radio 3, shortened and printed in 'Science As An Education', Nature (27 Jan ), , Bondi, (then Chief Scientific Adviser to the Ministry of Defence), argues for a view of science as an education of the mind, rather than as professional training, saying “My thesis is that science should be taught like the classics”.

    A theory is scientific only if it can be disproved. But the moment you try to cover absolutely everything the chances are that you cover nothing.

    Bondi–Metzner–Sachs group

    Asymptotic symmetry group of General Relativity

    In gravitational theory, the Bondi–Metzner–Sachs (BMS) group, or the Bondi–Van der Burg–Metzner–Sachs group, is an asymptotic symmetry group of asymptotically flat, Lorentzian spacetimes at null (i.e., light-like) infinity. It was originally formulated in by Hermann Bondi, M. G. Van der Burg, A. W. Metzner[1] and Rainer K. Sachs[2] in order to investigate the flow of energy at infinity due to propagating gravitational waves. Instead of the expected ordinary four spacetime translations of special relativity associated with the well-known conservation of momentum and energy, they found, much to their puzzling surprise, a novel infinite superset of direction-dependent time translations, which were named supertranslations. Half a century later, this work of Bondi, Van der Burg, Metzner, and Sachs is considered pioneering and seminal.[3] In his autobiography, Bondi considered the work as his "best scientific work".[4]:&#;79&#; The group of supertranslations is key to understanding the connections to quantum fields and gravitational wave memories.
