The history of the space race and the conquest of the Moon is studded with numerous milestones achieved thanks to thousands of researchers, technicians, engineers, mathematicians and programmers. Many of the people involved worked in the shadows, including a group of mathematicians and programmers known as "human computers". Katherine Johnson (born Coleman; August 26, 1918 - February 24, 2020) led a mathematical team whose work ushered NASA's pioneering feats since the early 1950s, culminating in the landing by Neil Armstrong and Buzz Aldrin on the Moon in 1969. She was also the first woman to sign NASA science papers, a prerogative reserved exclusively for men until then. Her work in the west wing of the Langley Research Center at the helm of the so-called "colored computers", a group of brilliant African-American mathematicians and programmers, was celebrated in the famous 2016 film "Hidden Figures". In this volume we want to explain to the public the scientific content of six scientific articles written by Johnson, accompanying the comments with the scientist's original articles, rewritten and improved. The landing on the Moon, the rescue of the Apollo 13 crew, the successful orbital launch of John Glenn, are just some of the great achievements of Katherine Johnson and the many women who worked behind the scenes of the space race.

This study investigates the topic of Eco- sustainability in the Jeanswear sector. The objectives are (1) to focus on Sustainable Development and Green Marketing in the Denim industry, (2) substantiate all of the theory through the tangible case of Levi's(r) Eco Jeans and (3) rank the factors that consumers value while making jeans purchase decisions. The survey instruments consist of both a questionnaire and of a qualitative research. The data stemming from the questionnaire are analyzed using factor analysis and the most important criterion for jeans assessment turns out to be related to Practicality. A structural model is developed in order to test whether the Eco- sustainability factor is influenced by some sociographical variables: the findings are thoroughly illustrated. Based on the evidence of the model, on the results obtained through the qualitative and quantitative research and on the observation of the market and of society, recommendations on "green" strategies for the companies active in the Denim industry, and in particular for Levi Strauss & CO., are provided. Finally, hypotheses for future research are also presente
