Answer the question at the end by quoting:

William Thomson, 1st Baron Kelvin,  (26 June 1824 - 17 December 1907) was a Scots-Irish mathematical physicist and engineer who was born in Belfast in 1824. At the University of Glasgow he did important work in the mathematical analysis of electricity and formulation of the first and second laws of thermodynamics, and did much to unify the emerging discipline of physics in its modern form. He worked closely with mathematics professor Hugh Blackburn in his work.
Though now eminent in the academic field, Thomson was obscure to the general public. In September 1852, he married childhood sweetheart Margaret Crum, daughter of Walter Crum; but her health broke down on their honeymoon and, over the next seventeen years, Thomson was distracted by her suffering. On 16 October 1854, George Gabriel Stokes wrote to Thomson to try to re-interest him in work by asking his opinion on some experiments of Michael Faraday on the proposed transatlantic telegraph cable.  Faraday had demonstrated how the construction of a cable would limit the rate at which messages could be sent - in modern terms, the bandwidth. Thomson jumped at the problem and published his response that month. He expressed his results in terms of the data rate that could be achieved and the economic consequences in terms of the potential revenue of the transatlantic undertaking. In a further 1855 analysis, Thomson stressed the impact that the design of the cable would have on its profitability.  Thomson contended that the signalling speed through a given cable was inversely proportional to the square of the length of the cable. Thomson's results were disputed at a meeting of the British Association in 1856 by Wildman Whitehouse, the electrician of the Atlantic Telegraph Company. Whitehouse had possibly misinterpreted the results of his own experiments but was doubtless feeling financial pressure as plans for the cable were already well under way. He believed that Thomson's calculations implied that the cable must be "abandoned as being practically and commercially impossible."  Thomson attacked Whitehouse's contention in a letter to the popular Athenaeum magazine, pitching himself into the public eye. Thomson recommended a larger conductor with a larger cross section of insulation. However, he thought Whitehouse no fool and suspected that he might have the practical skill to make the existing design work. Thomson's work had, however, caught the eye of the project's undertakers and in December 1856, he was elected to the board of directors of the Atlantic Telegraph Company.

What are other interesting aspects of his calculation methods?

Thomson recommended a larger conductor with a larger cross section of insulation.

IN: Scarlett Ingrid Johansson was born in the Manhattan borough of New York City, New York. Her father, Karsten Olaf Johansson, is an architect originally from Copenhagen, Denmark, and her paternal grandfather, Ejner Johansson, was an art historian, screenwriter and film director, whose own father was Swedish. Johansson's mother, Melanie Sloan, a producer, comes from an Ashkenazi Jewish family of Polish and Belarusian descent. She has an older sister, Vanessa, also an actress; an older brother, Adrian; and a twin brother, Hunter.

Johansson has been called "ScarJo" by the media and fans, but dislikes the nickname, finding it lazy, flippant and insulting. She is described as a sex symbol by the media, which considers her lips, green eyes, and voice among her trademarks. The Sydney Morning Herald describes Johansson as "the embodiment of male fantasy". During the filming of Match Point, director Woody Allen commented on her attractiveness. In 2014, New Yorker film critic Anthony Lane wrote that "she is evidently, and profitably, aware of her sultriness, and of how much, down to the last inch, it contributes to the contours of her reputation." Johansson said that she disliked being sexualized, and that a preoccupation with a person's attractiveness does not last. She lost the lead role in The Girl with the Dragon Tattoo (2011) as its director David Fincher thought she was "too sexy" for the part.  Johansson ranks highly in several beauty listings. Maxim included her in their Hot 100 from 2006 to 2014. She has been named "Sexiest Woman Alive" twice by Esquire (2006 and 2013), and has been included in similar listings by Playboy (2007), Men's Health (2011), and FHM (since 2005). She was named GQ's Babe of the Year in 2010. Madame Tussauds New York museum installed a wax sculpture of her in 2015.  Johansson was invited to join the Academy of Motion Picture Arts and Sciences in June 2004. In 2006, Johansson appeared on Forbes' Celebrity 100, and again in 2014 and 2015. Johansson received a star on the Hollywood Walk of Fame in May 2012. In 2014, 2015, and 2016, she was one of the highest-paid actresses, with annual earnings of $17 million, $35.5  million, and $25 million, respectively. She was the highest-grossing actor of 2016, with a total of $1.2 billion. As a result, IndieWire praised her for taking on risky roles. As of May 2017, Johansson is the highest-grossing actress of all time in North America, with her films making over $3.6 billion.  Johansson has appeared in advertising campaigns for Calvin Klein, Dolce & Gabbana, L'Oreal, and Louis Vuitton, and has represented the Spanish brand Mango since 2009. Johansson was the first Hollywood celebrity to represent a champagne producer, appearing in advertisements for Moet & Chandon. In January 2014, the Israeli company SodaStream, which makes home-carbonation products, hired Johansson as its first global brand ambassador, a relationship that commenced with a television commercial during Super Bowl XLVIII on February 2, 2014. This proved controversial, as SodaStream is based in Israeli-occupied territory in the West Bank.

What has Johansson done that considers her a sex symbol by the media?
