THE Nobel Prize in physics this year has been shared by Roger Penrose, the mathematical physicist, for his work on the theoretical basis of black holes, and Reinhard Genzel, and Andrea Ghez, two astronomers, who led independent teams, for verifying the existence of such a black hole at the centre of our Milky Way galaxy.  Penrose showed that the consequence of Einstein’s general theory of relativity is the formation of black holes, not simply of collapsing stars, but also in certain dense regions of space.  Such black holes capture everything: nothing can come out, not even light.

AS the pandemic marches through the world, a number of countries seemed to have given up the fight against Covid-19, and are now waiting for a vaccine to stop the pandemic.

ON September 7, 2020, the Defence Research & Development OrganiSzation (DRDO) successfully conducted a test of its wholly indigenous Hypersonic Technology Demonstrator Vehicle (HSTDV) which has been under development for well over a decade.HSTDV was launched aboard an Agni missile booster rocket from the APJ Abdul Kalam testing range on Wheeler Island off Balasore, Odisha, at 11:03 am.

TWO news items about India have figured prominently, one a nearly 24 per cent drop in India’s GDP  the previous quarter and the other that India has taken over as the new epicentre of the global pandemic with its figures for new cases crossing even the US numbers. The 24 per cent drop in GDP for the second quarter is the biggest drop of any major economy in the world for a quarter. The comparable US figures are 9.5 per cent and Japan’s 7.6 per cent drop in the same quarter.
