    The Science of Decisions

    Psychologist Joe Kable explores the neurological and psychological workings of choice.

    You may not realize it, but you just made a decision: namely, to read (or at least start to read) this article. Why? What process just occurred in your brain to cause you to be reading this sentence right now? How and why did you make that decision at that moment?

    Before Baby Talk

    Senior Rachel Romeo uses eye movements to study the impact of hearing impairments on infant language learning.

    In taking American Sign Language to fulfill her foreign language requirement, Rachel Romeo, C'11, often interacted with the Philadelphia Deaf community. She came across several people who said they'd suffered ear infections or diseases like meningitis in early childhood, and as a result, had developed hearing impairments that had gone undetected.

    Conversations on Neuroscience and Society

    SAS faculty share their insights on the human brain.

    Everything from education to warfare comes down to the workings of the human mind, and now the mind itself is being understood in terms of the brain. Across numerous disciplines, Penn Arts and Sciences faculty are studying this amazing three-pound organ and the insights it is offering on diverse human problems.

    Math Mystery

    Mathematicians Phillip Gressman and Robert Strain solve a 140-year old equation describing the motion of gas molecules.

    During the late 1860s and 1870s, when steam-powered technology was at its height, scientists were eager to understand the mechanisms underlying their empirical observations of how the temperature, volume and pressure of gaseous material interacted. In 1872, physicists Ludwig Boltzmann and James Clerk Maxwell developed a foundational equation predicting the motion of gas molecules.
