Are the magentic poles reversing?
Study of the question Are the magnetic poles reversing?" Ian McCrea, Rutherford Appleton Laboratory. Using magnetic models, scientist study the million plus year cycle of the pole reversal. RUn time 03:31.
Why study the magnetosphere at the poles?
David Murr of Dartmouth College explains why study the magnetosphere at the Poles: the closer to the pole, the closer you are to the outer boundaries of the Earth. In doing this, he also sees the connection between the people and the land. Run time 02:47.
Why Study the Magnetosphere at the Poles? - Continued
The discussion Why study the magnetosphere at the poles? is continued by Shin-ichiro Oyama – STEL, Nagoya who notes that there are more dramatic changes at the poles, e.g., the aurora. He is intrigued by the many things still to be explored and the beauty of the Northern climate. Run time 01:23.
6.541J Speech Communication (MIT)
6.541J surveys the structural properties of natural languages, with special emphasis on the sound pattern. Topics covered include: representation of the lexicon; physiology of speech production; articulatory phonetics; acoustical theory of speech production; acoustical and articulatory descriptions of phonetic features and of prosodic aspects of speech; perception of speech; models of lexical access and of speech production and planning; and applications to recognition and generation of speech b
Kepler - A Search for Habitable Planets
Kepler is a critical component in NASA's broader efforts to ultimately find and study planets where Earth-like conditions may be present. Kepler looks for the Habitable Zone... which is where scientists believe that water may be. Professional video. Run time 07:27.
12.802 Wave Motions in the Ocean and Atmosphere (MIT)
This course is an introduction to basic ideas of geophysical wave motion in rotating, stratified, and rotating-stratified fluids. Subject begins with general wave concepts of phase and group velocity. It also covers the dynamics and kinematics of gravity waves with a focus on dispersion, energy flux, initial value problems, etc. Also addressed are subject foundation used to study internal and inertial waves, Kelvin, Poincare, and Rossby waves in homogeneous and stratified fluids.

14.451 Dynamic Optimization Methods with Applications (MIT)
This course focuses on dynamic optimization methods, both in discrete and in continuous time. We approach these problems from a dynamic programming and optimal control perspective. We also study the dynamic systems that come from the solutions to these problems. The course will illustrate how these techniques are useful in various applications, drawing on many economic examples. However, the focus will remain on gaining a general command of the tools so that they can be applied later in other cl
