Turing Machines and Algorithmic Information
Contrast Shannon's code- and communication-based approach to information with a new, algorithmic way of thinking about the problem in terms of descriptions and computations. See how this idea relates to Alan Turing's theoretical universal computing machine, which underlies the operation of all digital computers.
The Science of Information - From Language to Black Holes
The science of information is the most influential, yet perhaps least appreciated field in science today. Never before in history have we been able to acquire, record, communicate, and use information in so many different forms. Never before have we had access to such vast quantities of data of every…
Top Secret Rosies
PBS
In 1942 a secret U.S. military program was launched to recruit women to the war effort. But unlike the efforts to recruit Rosie the Riveter to the factory, this clandestine search targeted female mathematicians who would become human 'computers' for the U.S. Army. From the bombing of Axis Europe to…
Official Secrets
Episode 2 of Yes, Prime Minister
The former Prime Minister is writing his memoirs - which have to be submitted for security clearance. It seems as though one chapter in the book will portray Jim in very bad light.
Proportion: Accurate Proportion and Measure
Episode 12 of How to Draw
Study key tools artists use to arrive at correct proportions. In particular, learn how to use an analog clock face as a way to quantify angles, how to use a standard unit of measure to measure across the picture plane, and how to use level and plumb lines. Then put…
AC/DC
Direct current (DC) is electric current that flows in one direction; alternating current (AC) flows back and forth. Learn how capacitors and inductors respond to AC by alternately storing and releasing energy. Combining a capacitor and inductor in a circuit provides the electrical analog of simple harmonic motion introduced in…
Horse Races and Stock Markets
One of Claude Shannon's colleagues at Bell Labs was the brilliant scientist and brash Texan John Kelly. Explore Kelly's insight that information is the advantage we have in betting on possible alternatives. Apply his celebrated log-optimal strategy to horse racing and stock trading.
Cryptanalysis and Unraveling the Enigma
Unravel the analysis that broke the super-secure Enigma code system used by the Germans during World War II. Led by British mathematician Alan Turing, the code breakers had to repeat their feat every day throughout the war. Also examine Claude Shannon's revolutionary views on the nature of secrecy.
The Transformability of Information
What is information? Explore the surprising answer of American mathematician Claude Shannon, who concluded that information is the ability to distinguish reliably among possible alternatives. Consider why this idea was so revolutionary, and see how it led to the concept of the bit--the basic unit of information.
Photographic Memory
Filmmaker Ross McElwee (Sherman's March, Bright Leaves) finds himself in frequent conflict with his son, a young adult who seems addicted to and distracted by the virtual worlds of the internet. To understand his fractured love for his son, McElwee travels back to St. Quay-Portrieux in Brittany for the first…
The Joy of the NumberĀ e
Episode 15 of The Joy of Mathematics
Another indispensable number to learn is e = 2.71828 ... Defined as the base of the natural logarithm, e plays a central role in calculus, and it arises naturally in many spheres of mathematics, including calculations of compound interest.
The Connection: Mind Your Body
At 24 years old, filmmaker Shannon Harvey was diagnosed with an autoimmune disease. Her immune system had become hyperactive and was attacking normal, healthy tissues. Her muscles and joints were inflamed and she was told if her disease progressed she could end up with organ failure, or wheelchair bound. In…
