Professor Blight finishes his lecture series with a discussion of the legacies of the Civil War. Since the nineteenth century, Blight suggests, there have been three predominant strains of Civil War memory, which Blight defines as reconciliationist, white supremacist, and emancipationist. The war has retained a political currency throughout the years, and the ability to control the memory of the Civil War has been, and continues to be, hot...more

In this last session on the Republic, the emphasis is on the idea of self-control, as put forward by Adeimantus in his speech. Socrates asserts that the most powerful passion one needs to learn how to tame is what he calls thumos. Used to denote "spiritedness" and "desire," it is associated with ambitions for public life that both virtuous statesmen as well as great tyrants may pursue. The lecture ends with the platonic idea of justice as ...more

Karl Deisseroth is pioneering bold new treatments for depression and other psychiatric diseases. By sending pulses of light into the brain, Deisseroth can control neural activity with remarkable precision. In this short talk, Deisseroth gives an thoughtful and awe-inspiring overview of his Stanford University lab's groundbreaking research in "optogenetics".

Sex allocation is an organism's decision on how much of its reproductive investment should be distributed to male and female functions and/or offspring. Under most conditions, the optimal ratio is 50:50, but that can change under certain circumstances. Sex allocation determines what sexes sequential hermaphrodites should be at each part of their life as well as how simultaneous hermaphrodites should behave. Some species have more control o...more

Professor Freeman discusses colonial attempts to unite before the 1760s and the ways in which regional distrust and localism complicated matters. American colonists joined together in union three times before the 1760s. Two of these attempts were inspired by the necessity of self-defense; the third attempt was instigated by the British as a means of asserting British control over the colonies.

Krishna Shenoy is creating "brain-computer interfaces" that will enable paralyzed patients to control prosthetic arms and computer cursors. In this short talk, Shenoy describes how his team of Stanford researchers has built a system that achieves typing at 15 words-per-minute, just by "thinking about it".

Launching the product with T-Mobile helped get the product out on the market and got others interested in the technology, making it easier for Danger to acquire other partners. Still, it was important for Danger not to be seen as a outsource development shop of T-Mobile and so they took steps to maintain control.

Abortion is very common both worldwide and in the US. There is one abortion for every 3.2 live births. In places where contraception is not used, abortion is used as birth control. Neither legal nor religious proscriptions have a strong effect on abortion rates. In countries where abortion is illegal, maternal death rates are extraordinarily high. Legal, medically done abortions are safer than getting pregnant. Psychological responses depe...more

Komisar describes a great entrepreneur as someone that works hard and knows how to take advantage of new opportunities. These opportunities need not be created by the entrepreneur, he says, but by others and the market around them. It is also important to note that even great entrepreneurs fail for reasons beyond their control.

Just how near are we to using our brains routinely to control machines for work or leisure purposes? Will we be able to improve the performance of our existing brains? Have advances in neuroscience, neural network modelling and the physical sciences led us to the point where it could soon be possible to create artificial, nanoscale brains and where might such technology lead us?
