Woohoo!!! Thx, Tilt! I feel special now. And momma always told me I was special... :lmao:

'Sup? You in lockdown, too?

Yup. Here for the last 50 days the lockdown was draconian in nature with cops beating people up who venture outside their front doors, confiscating cars and scooters and any other vehicle that violated the lockdown, all shops closed, forced stay-inside-your-house orders etc. No public transport of any kind etc. No alcohol shops - many people died or commited suicide because of withdrawal syndrome.



Now over the last week things have opened up except for barber-shops and women's salons (because touching is involved), malls, movie theatres etc. And hallelujah, alcohol shops are open again (caused massive crowds and disorderliness when they opened because people were starved of alcohol).


State borders are still restricted to only those whose travel is absolutely essential, and that too only with passes issued by each state government that one needs to pass through, limited trains and buses started only to transport people stranded in other states due to the sudden declaration of lockdown (we were given four hours notice at 8 p.m.). But even then, once you arrive at the destination state you're forced into a 14-day quarantine the moment you cross the state border - not at home, but at designated facilities - at your cost.


The economy is utterly and completely screwed, millions and millions have lost their jobs, livelihoods, and lives because of this. Millions of the poor died of starvation, millions of stranded labourers were left with no money to feed themselves, and no place to stay because they usually were provided accomodation at their work-sites; and when they closed down due to the lockdown these people were left with nowhere to go or be.


So, millions started to walk hundreds of miles to try and reach their hometowns where they had left their wives and children behind, many died on the way due to starvation, many were beaten up and punished by cops who just took pleasure and vented their frustrations by beating up anyone who came within view etc.


Things are slowly opening up now, restrictions are not so draconian any more, cops decided to stay home now because of all the "work" they did during lockdown, and so there's nobody to enforce any laws. People just do as they please with no one to question them.


With all that, there are also millions of people who are helpful, nice, generous to a fault, honest, etc. So, it is not all bad.


Hospitals and medical facilities are opening up again for non-Covid related issues. Until now they were prohibited from doing anyting but Covid, so, heart-attacks, dialysis, chemo, emergency services, essential surgeries etc. were all shut down and people died because of lack of access to medical help.


But hey, India has faced worse and has come out successfully, so, this too shall pass and everythiong will be back to normal with people bitching about traffic and Left-wingers, hindu-muslim problems and lynching people who speak against the government etc.


Cheers

Room-temperature superconductivity has been achieved for the first time

Room-temperature superconductors—materials that conduct electricity with zero resistance without needing special cooling—are the sort of technological miracle that would upend daily life. They could revolutionize the electric grid and enable levitating trains, among many other potential applications. But until now, superconductors have had to be cooled to extremely low temperatures, which has restricted them to use as a niche technology (albeit an important one). For decades it seemed that room-temperature superconductivity might be forever out of reach, but in the last five years a few research groups around the world have been engaged in a race to attain it in the lab.

One of them just won.

In a paper published today in Nature, researchers report achieving room-temperature superconductivity in a compound containing hydrogen, sulfur, and carbon at temperatures as high as 58 °F (13.3 °C, or 287.7 K). (...) the new record was attained under extremely high pressures—roughly two and a half million times greater than that of the air we breathe.

(...)

In the work reported in today’s paper, researchers from the University of Rochester and colleagues first mixed carbon and sulfur in a one-to-one ratio, milled the mixture down to tiny balls, and then squeezed those balls between two diamonds while injecting hydrogen gas. A laser was shined at the compound for several hours to break down bonds between the sulfur atoms, thus changing the chemistry of the system and the behavior of electrons in the sample. The resulting crystal is not stable at low pressures—but it is superconducting. It is also very small—under the high pressures at which it superconducts, it is about 30 millionths of a meter in diameter.

The exact details of why this compound works are not fully understood—the researchers aren’t even sure exactly what compound they made. But they are developing new tools to figure out what it is and are optimistic that once they are able to do so, they will be able to tweak the composition so that the compound might remain superconducting even at lower pressures.

Getting down to 100 gigapascal—about half of the pressures used in today’s Nature paper—would make it possible to begin industrializing “super tiny sensors with very high resolution,”
