Description
Begin the show with card tricks in which mathematics is clearly being used, but the secret is not easy to figure out. Learn the invariant principle: Some qualities stay the same in a deck even though the order of cards is changing. End with what Professor Benjamin calls the "tear-able" trick, being careful to use cards that you don't mind wrecking.

Description
Probe the quantum events that underlie color vision, discovering the role of the retinal molecule in detecting different frequencies of photons as they strike cone cells in the eye's retina. Also investigate the source of color blindness, most common in men, as well as its inverse, tetrachromacy, which is the ability to see an extra channel of color information, possessed by some women.

Description
While the Venusian carbon dioxide atmosphere has resulted in a runaway greenhouse effect and the hottest surface temperature in the solar system, the Earth and Venus actually contain about the same amount of carbon. Explore the forces that resulted in the extreme atmospheric differences between these two otherwise-similar planets.

Now that the versatility of negative feedback has been demonstrated, adjust the strength of negative feedback in op-amp circuits to build amplifiers with whatever gain you choose. Create an amplifier that sums two or more inputs, see a circuit that converts current to voltage, and explore the design and operation of an op-amp-based light meter.

Description
Focus on standing waves of electrons around nuclei, seeing how the periodic table of elements results from what electrons do naturally: fall into the lowest energy state given the total electric charge, existing electron population, and other features of an atom. Learn the Pauli exclusion principle and a handy mnemonic for remembering the terminology for atomic orbitals, such as 1s, 2p, and 3d.

Description
By combining logic gates and positive feedback, obtain circuits with two stable states. These "flip-flop" circuits "remember" their current states until they are forced into the opposite state. Learn the inner workings of several types of flip-flops as they lay the foundations for memory circuits.

Explore peak detectors that "remember" the maximum voltage reached, as well as Schmitt triggers whose output retain their value until the input changes sufficiently to "trigger" a change in the output. Use these concepts to design a practical circuit: an alarm to warn if your freezer's temperature has been above freezing.

Observe how circuit designers have formulated a wide array of schemes for converting analog signals to digitally encoded information. See how flash converters, integrating converters, and feedback converters use very different methods to accomplish the same goal, and weigh the situational costs and benefits of each.

Description
Analyze how metals conduct electricity, discovering that, in a sense, electrons "surf" from one metal atom to the next on a quantum mechanical wave. Probe the causes of electrical resistance and why metals can never be perfect conductors. Finally, use the Pauli exclusion principle to understand the optimum distribution of electrons in the different quantum states of metal atoms.

Review the major theories proposed by physicists trying to make sense of the paradoxes of the quantum world. Look at the Copenhagen interpretation, Einstein's realist view, the many worlds interpretation, quantum Bayesianism, non-local hidden variables, and other creative attempts to explain what is going on in a realm that seems to be governed by probability alone.

Professor Benjamin shows how to play cards like someone who would be thrown out of a casino. Learn the Jonah principle for always winning at poker. Get a "feel" for counting cards and develop the knack for telepathically communicating a hidden card to an assistant. Finally, who could claim to be a card shark without a trick that turns up four aces every time?

Description
Watch what happens when electrons are put into wave forms that differ from standing waves. Your goal is to understand why some of these superposition states are unstable. Professor Carlson notes that the sloshing of an electron back and forth in an unstable state causes it to act like an antenna, radiating away energy until it falls to a lower energy level.

What accounts for the dramatic difference between diamond and graphene (a sheet of graphite one atom thick), both of which are composed of pure carbon? Study the role of electrons in molecular bonds, applying your knowledge of electron standing waves. In carbon, such waves make possible several types of bonds, which in diamond and graphene result in remarkably different physical properties.

Study the most celebrated challenge to the Copenhagen interpretation of quantum mechanics: the paradox proposed by Albert Einstein and his collaborators Boris Podolsky and Nathan Rosen (and later updated by David Bohm). Is quantum mechanics an incomplete theory due to hidden variables that guide the outcome of quantum interactions? Examine this idea and the experiments designed to test it.

Return to the Heisenberg uncertainty principle to see how quantum uncertainty also extends to energy and time. This has a startling implication for energy conservation, suggesting that short-lived "virtual" particles can pop into existence out of nothing (as long as they don't stay around for long). Consider evidence for this phenomenon in the Lamb shift and Casimir effect.

You don't have to be a genius to look like one. Drawing on young volunteers, Professor Benjamin shows easy strategies for mentally multiplying numbers by 11, dividing numbers by 91, multiplying any numbers near 100, squaring numbers ending in 5, and other seemingly fearless feats of arithmetic, without use of a calculator.
