(Closing a chapter)


       (The end of an era)
Traveled to Bengaluru. Moved to Whitefield, Bengaluru. Joined GE Global Research (John F. Welch Technology Centre), Whitefield, Bangalore as Independent Consulting Scientist.



February 2018
Settled down in my new house, a cute 2 BHK in a nice housing society's 9th floor. 
 
Employed service/supply people. Started the kitchen. Got a new refrigerator and washing machine. Replaced the battery of my car Neelam (Maruti Alto 800). 
Started getting used to city life and corporate life.
Met up with pen-friend Ankita Choudhury after 15 years.
Manuscript accepted for publication in Polish Journal Engineering Transactions (1952), titled : 
Y.Verma and N.Datta, "EigenVector-based modeshape analysis and natural frequency classification of Mindlin’s plates using dynamic Timoshenko trial functions : non-classical edge conditions and aspect ratio study".

March 2018
Felt that the world is not a school but a market. Knowledge is important, but skill is more important. We have to grab opportunities. One has to understand what sells and align oneself to that, given one has the talent and interest in that. Academic is idealistic where principles matter. The world is realistic, where perceptions matter. 
Caught up with Chaddi buddy Amrita Mitra after 22 years; first at her home, and then at my home. We were in school together during 1987-1997, and in the same class during 1990-92 (Class 2-3). 
Fertility check at Morpheus Fertility Clinic, Indiranagar, with Dr. Haritha Rao. I got her contact from my BIL, since he and her husband were batch-mates in AFMC. My AFC and AMH numbers are doing good. Planned egg-freezing by the end of the calendar year.

April 2018
Manuscript submitted to Springer Journal of Marine Systems and Ocean Technology, N.Datta and Mohd. Atif Siddiqui, "Impact-induced flexural response of axially loaded uniform Timoshenko beams with non-classical ends".

Started doing causal water color painting after 6 years for de-stressing. Since my drawing is bad, the line-drawings were downloaded from the net, and I only did the painting.
Restarted swimming, after 8 years. Re-fell in love with the water. The reflexes came back within a few days.
Gave up morning tea after 7.5 years. Drastically reduced caffeine consumption. Started having more fruits (orange, banana, mango), peanuts, milk; and vegetables (carrot, radish, beet, bean, barbati, cauliflower, cabbage, capsicum, corn). Reduced starch consumption.

June 2018
This is the difference between Feb 02, 2018 and June 04, 2018. I lost ~5 kgs in four months. This is the change that happens when you start living the way you want (apne marzi se jeena). When stress reduces, it reduces the cortisol hormone in the bloodstream, which in turn increases leptin sensitivity (which give satiety signal upon eating adequately), regulates sleep patterns, revs up metabolism. 
Wonderful vacation with my partner in and around Bangalore. Visited Bannerghatta National park, Cubbon park, Tipu Sultan Summer palace, Bangalore Fort. Dined at the Dilleto (Bannerghatta National park), BBQ Nation (ITPL), Rice Bowl and CCD Sqaure (MG Road).

July 2018
Writing my first research grant proposal at GE GRC.
Meeting high school friend Kamalika Nandy after 20 years. We studied in the same class from 1993-1998.
Got back in touch with University of Michigan batch-mate Shaujo Biswas.
First foray into product development from scratch.
Submitted revised manuscript to Springer Journal titled Marine Systems and Ocean Technology, N.Datta and Mohd. Atif Siddiqui, "Impact-induced flexural response of axially loaded uniform Timoshenko beams with non-classical ends". 
Home makeover : bought new bed linen, pillows with protectors, bedside table, ironing table, suitcase, wallet, belt, earrings (10 pairs), dresses, shoes, plates, saucers, sauce-pan, cutlery, kitchen ware, gas-burner-stove, gym gloves. Dumped away all old stuff at Re-store, Whitefield. One suitcase of old clothes and one cartoon of old bed linen were given away to the NGO.

Learning ANSYS 18.0 (Workbench) : Useful tutorials in Simcafe served as the guideline. After 13 years, I learnt a computational too again :D .

Worked in FLUENT (now ANSYS-FLUENT) after 13 years. I had done my M.Tech project in propeller hydrodynamic performance analysis in FLUENT during 2005-06.

This month was a time of crises : both personal and professional. Life's dreams were crashing, plans were flopping, projects were failing. Mother had a biopsy for a breast lump, my paternal aunt's husband passed away, Father was keeping unwell. Stopped working out :(
I was exhausted and fatigued : needed medical help.
Got a new tenant for my parents' house in Kolkata.
Changed life's plan : going back to academia. Now I have a new target : writing sponsored project proposals. I my research expertise and experience must be used in solving real industry problems. From a professor, I am moving into becoming a consultant.

Packing up from Bangalore. It was a wonderful 11-months sojourn in this bustling city. Another unpaired journey : Back to IIT Kharagpur, refreshed and recharged to start a new chapter.

Finally, after ten years, I stopped holding my brain at ransom on academic publications/papers. The 10-year-era of paper-writing (2008-2018) finally came to an end. Now I am taking a quantum leap and starting a new struggle : sponsored research  projects. Looking forward to a great 2019.
