String Theory for Undergraduates




A torus is built from a cylinder of circumference 2π and length T by gluing the edges with a twist angle θ. The set of inequivalent tori is represented by the points in the orange region. In all these tori the shortest geodesic has length greater than or equal to 2π.

Instructors:

Prof. Barton Zwiebach

Prof. Alan Guth

MIT Course Number:

8.251

Level:

Undergraduate


    Course Features

    Course Description

    This course introduces string theory to undergraduate and is based upon Prof. Zwiebach's textbook entitled A First Course in String Theory. Since string theory is quantum mechanics of a relativistic string, the foundations of the subject can be explained to students exposed to both special relativity and basic quantum mechanics. This course develops the aspects of string theory and makes it accessible to students familiar with basic electromagnetism and statistical mechanics.

    Instructors:
    Prof. Sebastian Seung
    Level:
    Undergraduate


    Course Features

    Course Description

    This course gives a mathematical introduction to neural coding and dynamics. Topics include convolution, correlation, linear systems, game theory, signal detection theory, probability theory, information theory, and reinforcement learning. Applications to neural coding, focusing on the visual system are covered, as well as Hodgkin-Huxley and other related models of neural excitability, stochastic models of ion channels, cable theory, and models of synaptic transmission.

    Introduction to Astronomy

    Astronomers selected an uncluttered area of the sky in the constellation Ursa Major (the Big Bear) and pointed the Hubble Space Telescope at a single spot for 10 days. The many, separate exposures combined made the Deep Field image above. (Image courtesy of R. Williams, as presented on NASA's Astronomy Picture of the Day site.)


    Instructors:
    Prof. Saul Rappaport

    Level:
    Undergraduate


    Course Features

    Course Description

    Introduction to Astronomy provides a quantitative introduction to the physics of the solar system, stars, the interstellar medium, the galaxy, and the universe, as determined from a variety of astronomical observations and models.

    Instructors:

    Prof. Peter Schechter

    MIT Course Number:

    8.284

    Level:

    Undergraduate

    Course Description

    This course explores the applications of physics (Newtonian, statistical, and quantum mechanics) to fundamental processes that occur in celestial objects. The list of topics includes Main-sequence Stars, Collapsed Stars (White Dwarfs, Neutron Stars, and Black Holes), Pulsars, Supernovae, the Interstellar Medium, Galaxies, and as time permits, Active Galaxies, Quasars, and Cosmology. Observational data is also discussed.

    Instructors:
    Prof. Alan Guth

    Level:
    Undergraduate


    Course Features

    Course Description

    The Early Universe provides an introduction to modern cosmology. The first half deals with the development of the big-bang theory from 1915 to 1980, and latter half with recent impact of particle theory.
