"SOTEIGAI" - Outside our imagination

     We where known that Japan's Fukushima Daiichi Nuclear Power Plant accident was due to the damage in coolent supply line and caused core melt down.
     That was first rated as INES-5 accident (International nuclear event scale), then it was rated level 7 on 11 April 2011 by the Japanese government's nuclear safety agency.

International nuclear event scale (INES)
Emergency cooling system at Unit-1

      An independent report says Japan's response to the nuclear crisis that followed the March 11th earthquake and tsunami was woefully unprepared. The report issued Monday lists problems ranging from an erroneous assumption that an emergency cooling system was working, to a delay in disclosing dangerous radiation leaks.

     The interim report was compiled by an independent panel after interviewing over 400 people, including utility workers and government officials.

    The report criticized the Tokyo Electric Power and government regulators for failing to think beyond the risks for which the Fukushima nuclear plant was designed.

The report criticized the use of the term “soteigai,” meaning “outside our imagination,”

“This accident has taught us an important lesson on how we must be ready for soteigai,” it said.

The report, set to be finished by mid-2012, found workers at Tokyo Electric Power Co., the utility that ran Fukushima Dai-ichi, were untrained to handle emergencies like the power shutdown that struck when the tsunami destroyed backup generators setting off the world's worst nuclear disaster since Chernobyl.
There was no clear manual to follow, and the workers failed to communicate, not only with the government but also among themselves, it said.
Finding alternative ways to bring sorely needed water to the reactors was delayed for hours because of the mishandling of an emergency cooling system, the report said. Workers assumed the system was working, despite several warning signs it had failed and was sending the nuclear core into meltdown.
The report acknowledged that even if the system had kicked in properly, the tsunami damage may have been so great that meltdowns would have happened anyway.
But a better response might have reduced the core damage, radiation leaks and the hydrogen explosions that followed at two reactors and sent plumes of radiation into the air, according to the report. 
 The SOTEIGAI is not only for the workers of nuclear powerplant, we also have to learn "Never forget to think outside the box"...

One trillion shoots per second ... More than ultra slow motion camera...

     We are well known about ultra slow motion cameras which is using in cricket replies, that having the capacity of 1000 frames per second.


    MIT Media Lab researchers have created a new imaging system that can acquire visual data at a rate of one trillion frames per second. That's fast enough to produce a slow-motion video of light traveling through objects.


   The project director is an Indian Ramesh Rashkar, Associate professor, MIT Media lab.
Media Lab postdoc Andreas Velten, left, and Associate Professor Ramesh Raskar with the experimental setup they used to produce slow-motion video of light scattering through a plastic bottle.


   Media Lab postdoc Andreas Velten, one of the system’s developers, calls it the “ultimate” in slow motion: “There’s nothing in the universe that looks fast to this camera,” he says.

The man who knew infinity ...........

      Kumbakonam remembers the mathematical genius Srinivasa Ramanujan who brought glory to this humble town in Tamil Nadu.

"The Ramanujan@125 celebrations are being inaugurated in Chennai on Monday, December 26 by Prime Minister Manmohan Singh, who will declare 2012 to be the National Mathematics Year."



Srinivasa Ramanujan Iyengar Tamil: ஸ்ரீனிவாச ராமானுஜன் (December 22, 1887 – April 26, 1920) was an Indian mathematician. He is considered to be one of the most talented mathematicians in recent history. He had no formal training in mathematics. However, he still made large contributions to number theory, infinite series and continued fractions.
In 1913, a twenty-five-year-old Indian clerk with no formal education wrote a letter to G.H. Hardy, then widely acknowledged as the premier English mathematician of his time. Srinivasa Ramanujan begged Hardy's opinion regarding several ideas he had about numbers. Hardy realized that the letter was a work of genius.


Thus began one of the most productive and unusual scientific collaborations in history, that of an English don and an impoverished Hindu genius whose like has never been seen again. Hardy arranged for Ramanujan to sail for England, leaving behind his wife and other in Madras. Ramanujan's isolation from his family and the intensity of his work eventually took their toll, and within seven years of leaving India he was dead. For Hardy the collaboration with Ramanujan was "the one truly romantic incident of my life."




     The house in Kumbakonam, Tamil Nadu where Ramanujan grew up is now the Srinivasa Ramanujan Centre, established by SASTRA University and maintained as a monument from 2000.

           Roger Spottiswoode, best known for his James Bond film Tomorrow Never Dies, is working on a movie on mathematical genius Srinivasa Ramanujan, titled "The First Class Man", the film's scripting has been completed and shooting is being planned from next year.

“An American writer found Ramanujan and wrote a play about him for 10 years. He showed me the draft and I became interested. He wrote a script on it, which later won a prize at Tribeca for best script about science. We have nurtured it,” he says.

Talking about the title, Spottiswoode recalled a famous anecdote.

“When Ramanujan arrived in England, Hardy introduced him to Cambridge with a nice speech and called him ‘The First Class Man' and Ramanujan later thanked Hardy, saying ‘You are a first class man.' My film is more like King's Speech,” he says.
