NARAIN, Gaurav

@42_gravity Thanks 😊

@gnarain_ Congratulations!!

Our latest work on comparing the IR behavior of no-boundary and dS wave function at one loop. After a heavy computation the leading behavior is seen to be same. Work is however technically involved. arxiv.org/abs/2604.21736

🛰️New paper out on arXiv! We explore how dissipation and noise during inflation leave observable imprints in the CMB, using the Open EFT of Inflation (Open EFToI) 🧵👇 #cosmology #physics @Cambridge_Uni arxiv.org/pdf/2603.13473

Vow 👏🎉

Please apply for PhD positions under the National Quantum Mission (NQM) in our group. We have multiple opportunities for students to work on cold atom quantum memory and quantum network. We are also interested to host students to work with us on portable atomic clock development.

Chinese President Jiang Zemin Taught Limits Using Zhuangzi’s One-Foot Rod. In November 2001, then Chinese President Jiang Zemin visited Beijing University of Technology. During an impromptu stop in a calculus class discussing derivatives, he picked up chalk and wrote on the blackboard: Zhuangzi said: "A one-foot hammer (or rod), take half of it each day, and it will never be exhausted through eternity." (一尺之棰，日取其半，万世不竭。) He then wrote a mathematical formula to precisely capture its meaning, explaining: "This is our ancestors' extremely important idea of limits." This ancient paradox from Zhuangzi's "Tianxia" chapter beautifully illustrates the concept of infinite division and the limit approaching zero — a profound insight predating modern calculus by over two millennia.

Happy Chinese new year. May the year of Horse brings prosperity and happiness to all.

Video recorded in the mountains near Vancouver, Canada. It shows several crows playing in the snow. It's heartwarming to watch them roll down the hillside.

2nd talk of Season 3 in the GG series has been uploaded on the CHEP YouTube channel. youtube.com/watch?v=qDCjGl… We are really very thankful to Prof. Olga Papadoulaki (CPHT, Ecole Polytechnique) for giving an amazing talk in GG-seminar series.

@meowdib @FaustOrpheu Sure. Dm me your email

@gnarain_ @FaustOrpheu Could you add me as well?

@FaustOrpheu you can dm me your email, I will add it. Thanks

@gnarain_ Thanks, I'll subscribed later. Could you post subscribing link for convenience?

@FaustOrpheu We share link in mailing list after few days.

@gnarain_ Is there any link?

A single adult child taking care of elderly infirm parents is stressful. A single adult child having married another single child, and now having to take of 4 elderly infirm parents is stress times double. The adult couple tries to manage their jobs, their own kids well-being, household chores, the innumerable hospital visits of their elderly parents....their own mental and physical health goes for a toss. Similar is the case when one sibling goes abroad and the other sibling is left to take care of the elderly parents. The abroad child usually helps financially. But the physical stress and strain falls on the adult child staying back in India. Not discussing which is correct and which is wrong....all these are complex family dynamics and each family is different. Majority of adults in India still genuinely care for their elderly parents and in-laws. Perhaps, all that the adult child just needs is a kind word, a compassionate acknowledgement of all the hardwork that he/she is voluntarily and willfully undertaking. My pranaams to all such adult children. 🙏🏼 #ElderlyCare
