Professor Courtenay Raia lectures on science and religion as historical phenomena that have evolved over time. She examines the earlier mind-set before 1700 when into science fitted elements that came eventually to be seen as magical. The course also question how Western cosmologies became "disenchanted." Magical tradition transformed into modern mysticisms is also examined as well as the political implications of these movements. Includes...more
In addition to cultural controls acting to maximize fertility, there are important, and often competing, interests of individual families to limit fertility. Unwanted births are dealt with by infanticide in many cultures. Additionally, fertility is regularly controlled by limiting marriage within a culture. Another very important factor in population growth, especially in the tropics, is food availability. Heavy rains in the tropics wash n...more
Banks, which were first created in primitive form by goldsmiths hundreds of years ago, have evolved into central economic institutions that manage the allocation of resources, channel information about productive activities, and offer the public convenient investment vehicles. Although there are several types of banking institutions, including credit unions and Saving and Loan Associations, commercial banks are the largest and most importa...more
This lecture explores how the mismatch between evolution and the current food environment has changed people's relationship to food. Ancient societies had a vastly different food environment compared to modern day societies, which was characterized by unpredictable food supply, the threat of starvation, and a high priority to bank energy. The human brain evolved for this ancient food environment, which creates challenges in the modern food...more
Of all the diseases studied in this course, malaria has been responsible for the most human suffering. It has evolved alongside humans, and impacted human biology as well as civilization. In the former case, this impact is evident in genetic diseases like sickle-cell anemia which, while increasing vulnerability to a host of other illnesses, has the advantage of conferring substantial resistance to malaria. In social terms, malaria's debili...more
Wirt explains that the invention of the electric motor revolutionized the way factories operate. With steam power, there was one central boiler which dictated how the factory had to be organized. As electric motors evolved, it became possible to make small motors that could be distributed around the plant to provide power to individual machines allowing for greater flexibility. Now, electric motors are everywhere, he says....more

According to Wirt, PDAs have evolved over the last decade from just an address book and calendar to devices that can play movies and MP3s and carry much more information. In the next decade, he sees an increased ability to carry around many types of information.
Danger was able to break into the US market by convincing wireless carriers to adopt a fixed rate pricing scheme for the device, which is almost essential in the minds of Americans for using services like AIM and web surfing. The Asian and European markets are further ahead and calls are cheaper, making it more difficult for the Hiptop to be profitable.
While there are many differences between modern science and philosophy, there are still a number of lessons in modes of thought that scientists can take from philosophy. Scientists' ideas about the nature of science have evolved over time, leading to new ideas about falsifiability, creativity, revolutions, and the boundaries and limits of what can be accomplished by different types of science.
Dr. Paul Ewald speaks about how several pathogenic viruses have evolved over time to break down the cell's barriers to several types of cancer. He suggests that further research will aid in the discovery of additional viruses linked to the causation of cancer. The lecture is concluded with a panel discussion with Gary Schoolnik and Stanley Falkow.
(May 10, 2010) Robert Sapolsky completes his talk on sexual behavior in humans as well as other species, focusing on characteristics that create attractiveness. He then switches subject and talks about human aggression and how this has evolved and developed in different cultures.
