Some context: Rajinikanth was born on 12 December 1950, in a Maratha family in Bangalore, Mysore State (present day Karnataka). His mother was a housewife, and his father Ramoji Rao Gaekwad, a police constable, He was named Shivaji Rao Gaekwad after Chhatrapati Shivaji, a Maratha warrior King, and was brought up speaking Marathi at home and Kannada outside. Rajinikanth's ancestors hailed from Mavadi Kadepathar, Maharashtra and Nachikuppam, Tamil Nadu. He is the youngest of four siblings in a family consisting of two elder brothers (Satyanarayana Rao and Nageshwara Rao) and a sister (Aswath Balubhai).
In January 2011, Rajinikanth was slated to appear in Rana, a period film to be produced by Soundarya Rajinikanth and directed by K. S. Ravikumar, who would work with the actor for a third time. During the principal photography of the film on 29 April 2011, he suffered a mild foodborne illness on the sets, which led to vomiting, dehydration, and exhaustion. He was treated at St. Isabel's Hospital for a day before being discharged. Five days later, he was rushed to the same hospital again after suffering from breathlessness and fever. He was diagnosed with bronchitis and was kept at the hospital for a week, while also spending a few days in an intensive care unit. Several conflicting reports of discharge dates arose, as well as claims of Rajinikanth's health deteriorating. Two days after his last discharge, Rajinikanth was admitted to the Sri Ramachandra Medical College and Research Institute on 16 May 2011 for recurring respiratory and gastrointestinal problems. The hospital maintained that Rajinikanth was in stable condition and showed positive response to treatment. It was widely reported that he required a kidney transplantation, which was later denied by Dhanush. On 21 May 2011, Aishwarya Rajinikanth released a photo of her and Rajinikanth in his hospital ward, both posing with a thumbs signal, responding to fans' negative reaction to news reports. The hospital restricted unauthorised visitors. Rajinikanth's brother, Sathyanarayana Rao Gaekwad, reported that the cause of the sudden illness was due to stress from rapid weight-loss and changes in diet, as well as withdrawal of alcohol consumption and smoking cessation. After addressing fans in a 4-minute digitally recorded voice message to the media, Rajinikanth, under the advice of Amitabh Bachchan, travelled from Chennai to Singapore with his family on 21 May 2011, where he was to undergo further treatment for nephropathy at Mount Elizabeth Hospital. After spending over two weeks at the hospital, he was finally discharged on 15 June 2011 and continued to recuperate in Singapore, before returning to Chennai on 13 July 2011. Despite several failed attempts to restart Rana upon his return, Rajinikanth reprised his Enthiran character, Chitti, in the Bollywood science-fiction film Ra.One (2011) in a guest appearance alongside Shah Rukh Khan and Kareena Kapoor. In November 2011, it was decided that Rana would be shelved in favour of a new project with Rajinikanth, titled Kochadaiiyaan. The motion capture film, which is the first of its kind in India, was released in 2014 to positive reviews. Kochadaiiyaan, and the 3D release of Sivaji in 2012, made Rajinikanth the first Indian actor to have appeared in four different forms of world cinema: black-and-white, colour, 3D and motion capture. Following the completion of Kochadaiiyaan, Rajinikanth began work in Ravikumar's next directorial venture, titled Lingaa alongside Anushka Shetty and Sonakshi Sinha. The film was released on 12 December 2014, coinciding with his birthday, and received mixed reviews from critics. Rajinikanth's next film was director Pa. Ranjith's crime drama Kabali, produced by S. Thanu. The film was released in July 2016. Rajinikanth is filming for 2.0, a spiritual successor to Enthiran, that is scheduled for release in 2017. In August 2016, it was announced that he would work with Ranjith again for a new film produced by Dhanush.
What about in the present, what is he doing now
A: Rajinikanth is filming for 2.0, a spiritual successor to Enthiran, that is scheduled for release in 2017.
Some context: Sir George Gabriel Stokes, 1st Baronet, (; 13 August 1819 - 1 February 1903), was an Irish physicist and mathematician. Born in Ireland, Stokes spent all of his career at the University of Cambridge, where he served as Lucasian Professor of Mathematics from 1849 until his death in 1903. In physics, Stokes made seminal contributions to fluid dynamics (including the Navier-Stokes equations) and to physical optics. In mathematics he formulated the first version of what is now known as Stokes's theorem and contributed to the theory of asymptotic expansions.
Many of Stokes' discoveries were not published, or were only touched upon in the course of his oral lectures. One such example is his work in the theory of spectroscopy. In his presidential address to the British Association in 1871, Lord Kelvin stated his belief that the application of the prismatic analysis of light to solar and stellar chemistry had never been suggested directly or indirectly by anyone else when Stokes taught it to him at Cambridge University some time prior to the summer of 1852, and he set forth the conclusions, theoretical and practical, which he learnt from Stokes at that time, and which he afterwards gave regularly in his public lectures at Glasgow. These statements, containing as they do the physical basis on which spectroscopy rests, and the way in which it is applicable to the identification of substances existing in the sun and stars, make it appear that Stokes anticipated Kirchhoff by at least seven or eight years. Stokes, however, in a letter published some years after the delivery of this address, stated that he had failed to take one essential step in the argument--not perceiving that emission of light of definite wavelength not merely permitted, but necessitated, absorption of light of the same wavelength. He modestly disclaimed "any part of Kirchhoff's admirable discovery," adding that he felt some of his friends had been over-zealous in his cause. It must be said, however, that English men of science have not accepted this disclaimer in all its fullness, and still attribute to Stokes the credit of having first enunciated the fundamental principles of spectroscopy. In another way, too, Stokes did much for the progress of mathematical physics. Soon after he was elected to the Lucasian chair he announced that he regarded it as part of his professional duties to help any member of the university in difficulties he might encounter in his mathematical studies, and the assistance rendered was so real that pupils were glad to consult him, even after they had become colleagues, on mathematical and physical problems in which they found themselves at a loss. Then during the thirty years he acted as secretary of the Royal Society he exercised an enormous if inconspicuous influence on the advancement of mathematical and physical science, not only directly by his own investigations, but indirectly by suggesting problems for inquiry and inciting men to attack them, and by his readiness to give encouragement and help.
