@KyleMau Wating time for a TRC card is now insane. Even for a renewal you to provide biometric again with 18 months waiting time just for this.

📢Can we get rid of the order dependence of the Euler rotations involved in the PMNS mixing matrix?
📢Can we have `democratic' values for the neutrino mixing angles instead of nearly maximal mixing?
📣To answer we propose a SO(3) parameterization of the neutrino mixing matrix

In 2001, the University Grants Commission of India decided to introduce astrology as a science course in India. Back then, Indian scientists still used to protest this sort of thing and JV
Narlikar was one of most vocal.

Perhaps this event motivated JVN and his friends to run a double blind study on astrology some years later. Their methodology was simple. They considered two groups of children—one group was children with severe intellectual disabilities, the other was a typically developing group. Could astrologers tell which is which from their horoscopes?

Many prominent astrologers backed off from taking the study but 27 took it up. It didn’t take a horoscope to predict the result of this study—not a single one beat the null hypothesis (link to the paper 👇). Astrology busted (again).

Narlikar, Dabholkar and the likes were old school scholars who dedicated their time to championing rationalism and scientific temper in the country, even in the face of hostility, instead of chasing personal wealth and status. They don’t make them like that anymore.

@AirbnbHelp I've repeatedly requested an invoice from my host in Warsaw with no response. Airbnb support couldn't assist. As per Polish law, I have the right to an invoice. If the host can't provide it, I request a full refund. Please intervene. #ConsumerRights #AirbnbPoland

@nblqbl Thank you for this initiative. Looking forward to it!

A generalisation of the discrete dark matter (DDM) and scoto-seesaw frameworks to a scenario where light neutrinos are Dirac fermions. DM is stabilised by a remnant discrete symmetry emerging after spontaneous breaking of a non-Abelian discrete flavour symmetry: DDM; (1/2)
