Question: Prandtl numbers are named after a pioneer in what applied science?
Context: Robert Sidey Shaw (July 24, 1871 – February 7, 1953) was president of the Michigan State College of Agriculture and Applied Science (now Michigan State University) from 1928 to 1941.  Dormitory Shaw Hall in the center of campus south of the Red Cedar River is named in his honor.  His daughter, Sarah May Shaw, married John A. Hannah, who would succeed Shaw as president of the Michigan State College of Agriculture and Applied Science. The BYU College of Life Sciences was originally named the College of Biology and Agriculture.  It was formed in 1954 from the division of the College of Applied Science into this college and the College of Family Living, which was a partial predecessor of the College of Family, Home and Social Sciences.  While the Agronomy; Horticulture; Animal Husbandry; Industrial Arts and Drawing; and Bacteriology programs all came from the College of Applied Science the Botany; and Zoology and Entomology programs came from the College of Arts and Sciences.  Thomas L. Martin was the first dean of the College of Biology and Agriculture.  In 1954 the Agricultural Economics Department was moved from the College of Commerce to the College of Biology and Agriculture. The Prandtl number (Pr) or Prandtl group is a dimensionless number, named after the German physicist Ludwig Prandtl, defined as the ratio of momentum diffusivity to thermal diffusivity.  That is, the Prandtl number is given as: Dean Ho is a Professor in the Division of Oral Biology and Medicine and Division of Advanced Prosthodontics, Biomaterials, and Hospital Dentistry, as well as Co-Director of the Jane and Jerry Weintraub Center for Reconstructive Biotechnology at the UCLA School of Dentistry.  He is also a Professor of Bioengineering at the UCLA School of Engineering and Applied Science, where he directs Project NDX, a global effort to bring nanodiamond-modified therapies and personalized medicine technology platforms to the clinic.  He is also a member of the Jonsson Comprehensive Cancer Center and California NanoSystems Institute.  He was previously an Associate Professor in the Departments of Biomedical Engineering and Mechanical Engineering in the Robert R. McCormick School of Engineering and Applied Science, and Full Member of the Robert H. Lurie Comprehensive Cancer Center at the Feinberg School of Medicine of Northwestern University, Illinois, United States. Applied Science Technologist is a Canadian professional title awarded on the basis of academic qualification and work experience.  Abbreviated as A.Sc.T., some, but not all, Canadian provincial engineering and applied science technology associations offer this certification. Jean-Antoine Chaptal, comte de Chanteloup (5 June 1756 – 30 July 1832) was a distinguished French chemist, physician, agronomist, industrialist, statesman, educator and philanthropist.  His multifaceted career unfolded during one of the most brilliant periods in French science.  In chemistry it was the time of Antoine Lavoisier, Claude-Louis Berthollet, Louis Guyton de Morveau, Antoine-François Fourcroy and Joseph Gay-Lussac.  Chaptal made his way into this elite company in Paris beginning in the 1780s, and established his credentials as a serious scientist most definitely with the publication of his first major scientific treatise, the "Ėléments de chimie" (3 vols, Montpellier, 1790).  His treatise brought the term "nitrogen" into the revolutionary new chemical nomenclature developed by Lavoisier.  By 1795, at the newly established "École Polytechnique" in Paris, Chaptal shared the teaching of courses in pure and applied chemistry with Claude-Louis Berthollet, the doyen of the science.  In 1798, Chaptal was elected a member of the prestigious Chemistry Section of the "Institut de France".  He became president of the section in 1802 soon after Napoleon appointed him Minister of Interior (6 November 1800).  Chaptal was a key figure in the early industrialization in France under Napoleon and during the Bourbon Restoration.  He was a founder and first president in 1801 of the important Society for the Encouragement of National Industry and a key organizer of industrial expositions held in Paris in 1801 and subsequent years.  He compiled a valuable study, "De l'industrie française" (1819), surveying the condition and needs of French industry in the early 1800s.  Chaptal was especially strong in applied science.  Beginning in the early 1780s, he published a continuous stream of practical essays on such things as acids and salts, alum, sulfur, pottery and cheese making, sugar beets, fertilizers, bleaching, degreasing, painting and dyeing.  As a chemicals industrialist, he was a major producer of hydrochloric, nitric and sulfuric acids, and was much sought after as a technical consultant for the manufacture of gunpowder.  His reputation as a master of applied science, dedicated to using the discoveries of chemistry for the benefit of industry and agriculture, was furthered with the publication of his "L'Art de faire, de gouverner et de perfectionner les vins" (1801) and "La Chimie appliquée aux arts" (1806), works that drew on the theoretical chemistry of Lavoisier to revolutionize the art of wine-making in France.  His new procedure of adding sugar to increase the final alcohol content of wines came to be called "chaptalization."  In 1802, Chaptal purchased the Château de Chanteloup and its extensive grounds in Touraine, near Amboise.  He raised merino sheep and experimented there in his later years on a model farm for the cultivation of sugar beets.  He wrote his classic study of the application of scientific principles to the cultivation of land, the "Chimie appliquée à l'agriculture" (1823), and composed his important political memoir, "Mes souvenirs sur Napoléon"(1893).  Napoleon named Chaptal Count of the Empire (1808) and Count of Chanteloup (1810).  In 1819 he was named by Louis XVIII to the Restoration's Chamber of Peers. Ian Beausoleil-Morrison is an associate professor of mechanical and aerospace engineering at Carleton University in Ottawa, Ontario and an adjunct Associate Professor at both Dalhousie University and the University of Victoria.  He holds a Bachelor of Applied Science and a Master's of Applied Science from the University of Waterloo, and a Ph.D. from the University of Strathclyde, Scotland. Centralia College, an institution of higher learning located in Centralia, Washington, is a two-year institution and in 2012 began offering a Bachelor of Applied Science in Applied Management degree (BAS-AM) and now offers a Bachelor of Applied Science in Diesel Technology (BAS-D).  Founded in 1925, Centralia is the oldest continuously operating community college in the state of Washington.  As shown below, the college sits on 29 acre in the middle of the town of Centralia.  There is a branch education center, Centralia College East, in the town of Morton and the college offers a range of online and correspondence courses.  Overall the college serves an area of 2409 sqmi in Lewis County and southern Thurston County under the administrative classification of Community College District Twelve. Columbia Basin College (also known as CBC) is a college based in Pasco, Washington accredited by the Northwest Commission on Colleges and Universities.  The College offers English as a second language and General Educational Development (GED) prep classes, the Running Start program, plus many associate degrees (transfer, associate of applied science, associate of arts) and Bachelor of Applied Science (BAS) degrees.  The BAS programs are in Cyber Security, Project Management, and Applied Management.  The Applied Management program also offers a Healthcare Administration concentration. Ludwig Prandtl (4 February 1875 – 15 August 1953) was a German engineer.  He was a pioneer in the development of rigorous systematic mathematical analyses which he used for underlying the science of aerodynamics, which have come to form the basis of the applied science of aeronautical engineering.  In the 1920s he developed the mathematical basis for the fundamental principles of subsonic aerodynamics in particular; and in general up to and including transonic velocities.  His studies identified the boundary layer, thin-airfoils, and lifting-line theories.  The Prandtl number was named after him.
