Time Travel Tuesday #timetravel a look back at the Adafruit, maker, science, technology and engineering world
1831 – Michael Faraday discovers electromagnetic induction.
Faraday’s breakthrough came when he wrapped two insulated coils of wire around an iron ring, and found that upon passing a current through one coil a momentary current was induced in the other coil. This phenomenon is now known as mutual induction. The iron ring-coil apparatus is still on display at the Royal Institution. In subsequent experiments, he found that if he moved a magnet through a loop of wire an electric current flowed in that wire. The current also flowed if the loop was moved over a stationary magnet. His demonstrations established that a changing magnetic field produces an electric field; this relation was modelled mathematically by James Clerk Maxwell as Faraday’s law, which subsequently became one of the four Maxwell equations, and which have in turn evolved into the generalization known today as field theory. Faraday would later use the principles he had discovered to construct the electric dynamo, the ancestor of modern power generators and the electric motor.
1876 – Charles F. Kettering, American engineer and businessman, founded Delco Electronics is born.
Charles Franklin Kettering sometimes known as Charles “Boss” Kettering was an American inventor, engineer, businessman, and the holder of 186 patents. He was a founder of Delco, and was head of research at General Motors from 1920 to 1947. Among his most widely used automotive developments were the electrical starting motor and leaded gasoline. In association with the DuPont Chemical Company, he was also responsible for the invention of Freon refrigerant for refrigeration and air conditioning systems. At DuPont he also was responsible for the development of Duco lacquers and enamels, the first practical colored paints for mass-produced automobiles. While working with the Dayton-Wright Company he developed the “Bug” aerial torpedo, considered the world’s first aerial missile. He led the advancement of practical, lightweight two-stroke diesel engines, revolutionizing the locomotive and heavy equipment industries. In 1927, he founded the Kettering Foundation, a non-partisan research foundation. He was featured on the cover of Time Magazine on January 9, 1933.
1948 – Robert S. Langer, American chemical engineer, entrepreneur, and academic is born.
Robert Samuel Langer, Jr. FREng is an American chemical engineer, scientist, entrepreneur, inventor and the David H. Koch Institute Professor at the Massachusetts Institute of Technology. He was formerly the Germeshausen Professor of Chemical and Biomedical Engineering and maintains activity in the Department of Chemical Engineering and the Department of Biological Engineering at MIT. He is also a faculty member of the Harvard-MIT Division of Health Sciences and Technology and the David H. Koch Institute for Integrative Cancer Research. He is a widely recognized and cited researcher in biotechnology, especially in the fields of drug delivery systems and tissue engineering. His publications have been cited approximately 229,000 times and his h-index is 240. According to Google Scholar, Langer is one of the 10 most cited individuals in history. Langer is recognized as the most cited engineer in history. Langer’s research laboratory at MIT is the largest biomedical engineering lab in the world, maintaining over $10 million in annual grants and over 100 researchers. In 2015, Langer was awarded the Queen Elizabeth Prize for Engineering, the most influential prize in the world for engineering.
1959 – Stephen Wolfram, English-American physicist and mathematician is born.
Stephen Wolfram is a British-American computer scientist, physicist, and businessman. He is known for his work in computer science, mathematics, and in theoretical physics. He is the author of the book A New Kind of Science. In 2012 he was named an inaugural fellow of the American Mathematical Society.
As a businessman, he is the founder and CEO of the software company Wolfram Research where he worked as chief designer of Mathematica and the Wolfram Alpha answer engine. His recent work has been on knowledge-based programming, expanding and refining the programming language of Mathematica into what is now called the Wolfram Language. His book An Elementary Introduction to the Wolfram Language appeared in 2015 and Idea Makers appeared in 2016.
1982 – The synthetic chemical element Meitnerium, atomic number 109, is first synthesized at the Gesellschaft für Schwerionenforschung in Darmstadt, Germany.
Meitnerium is a chemical element with symbol Mt and atomic number 109. It is an extremely radioactive synthetic element (an element not found in nature that can be created in a laboratory). The most stable known isotope, meitnerium-278, has a half-life of 7.6 seconds, although the unconfirmed meitnerium-282 may have a longer half-life of 67 seconds. The GSI Helmholtz Centre for Heavy Ion Research near Darmstadt, Germany, first created this element in 1982. It is named for Lise Meitner, one of the discoverers of nuclear fission.
2013 – hackerspace is now a word in the Oxford dictionary
Pronunciation: /ˈhakəspeɪs/
noun
• a place in which people with an interest in computing or technology can gather to work on projects while sharing ideas, equipment, and knowledge:we’ve seen some folks at our local hackerspace try to patch into the remote control itself
