  Civil defence volunteers: Context: The Delhi Police recently issued a statement, pointing out that  civil defence personnel,  also known as  Delhi Civil Defence (DCD) volunteers,  have no power to stop people using police barricades and prosecute them for violation of Covid-19 appropriate behaviour such as not wearing masks. What’s the issue? From being lauded for their work during the pandemic to facing allegations of high-handedness, the role of the civil defence volunteers in the national capital has come under intense scrutiny in the recent past. One such incident recently turned into a full blown fist-fight between a group of civil defence personnel and general public near IIT-Delhi. So, who are these civil defence volunteers? In Delhi, these are men and women who  work under the command of the district magistrates. The  overall command lies with the divisional commissioner,  to which the DMs report. These volunteers are  governed by t...

  Muon g–2: New physics governing the laws of nature Part of : GS Prelims and GS – III – Sci & tech  In news Newly published results of an international experiment hint at the possibility of new physics governing the laws of nature. The experiment, called Muon g–2 (g minus two), was conducted at the US Department of Energy’s Fermi National Accelerator Laboratory (Fermilab). Key takeaways  The experiment studied a subatomic particle called the muon.  Its results do not match the predictions of the Standard Model, on which all particle physics is based.  The results instead reconfirm a discrepancy that had been detected in an experiment 20 years ago. Concluded in 2001, the Brookhaven experiment came up with results that did not identically match predictions by the Standard Model. The Muon g–2 experiment measured this quantity with greater accuracy. What is the Standard Model? The Standard Model is a rigorous theory that predicts the behaviour of the building b...
