Choosing a Career in Health
There are two lessons in this group. The first lesson is a lab activity that illustrates the importance of hand washing as a way to prevent the spread disease. The second lesson includes discussion of various careers in the health field and allows students to explore careers utilizing various resources.
Topological Features of a Compressible Plasma Vortex Sheet: 6 Cases
The Voyager and Pioneer Spacecraft have detected large-scale quasi-periodic plasma fluctuations in the outer heliosphere beyond 20 AU. A plasma vortex sheet model can explain these fluctuations and the observed correlations between various physical variables. The large scale outer heliosphere is modeled by solving the 3-D compressible magneto-hydrodynamic equations involving three interacting shear layers. Computations were done on a Cray computer at the NASA Center for Computational Sciences. S
Bastille Day Flare Animation
Fly-in of TRACE full sun image to the flare location. Fade to a model of the field lines with a magnetogram of the solar surface. Pull back out to display a movie of flare images. This version uses lens flares to illustrate matter motion along the field lines.
Bastille Day Flare without Matter Motion
Fly-in of TRACE full sun image to the flare location. Fade to a model of the field lines with a magnetogram of the solar surface. Pull back out to display a movie of flare images. This version does not show the matter motion along the field lines.
When a large bundle of magnetic field lines breaks through the Suns surface, a sunspot can form. Sometimes, a smaller spot will emerge nearby, creating a magnetically complex region where particles are energized and then violently expelled. Supercomputer models show that rearranging magnetic field lines ...
Mapping Magnetic Influence
This lesson allows students to explore magnets and the region of influence around a magnet called a magnetic field. They will learn that magnets exert a force on a magnetically sensitive object without coming into direct contact. Students will create a map of the magnetic influence around the magnet.
Magnetic Globe Lithograph
This activity demonstrates what a dipole magnetic field looks like in 3D. It was developed because the commonly used classroom demo (iron filings on a sheet of paper on top of a bar magnet) leads to student misconception that magnetic fields are two-dimensional. The reverse side of the litho features ...
Scaling of CMOS devices into the nanometer regime leads to increased processing cost. In this regard, the field of Computational Electronics is becoming more and more important because device simulation offers unique possibility to test hypothetical devices which have not been fabricated yet and it ...
Nanoscale Antenna Apertures
This presentation will discuss light concentration and enhancement in nanometer-scale ridge aperture antennas. Resent research, including numerical simulations and near field optical measurements has demonstrated that nanoscale ridge antenna apertures can concentrate light into nanometer domain. More ...
Nanoelectronics and the Meaning of Resistance
The purpose of this series of lectures is to introduce the "bottom-up" approach to nanoelectronics using concrete examples. No prior knowledge of quantum mechanics or statistical mechanics is assumed; however, familiarity with matrix algebra will be helpful for some topics.
Quantum Dots are man-made artificial atoms that confine electrons to a small space. As such they have atomic-like behavior and enable the study of quantum mechanical effects on a length scale that is around 100 times larger than the pure atomic scale. Quantum dots offer application opportunities in ...
Why is Nanotechnology Multidisciplinary? A perspective of one EE
The field of nano-science and nano-technology covers a broad area of expertise. Classical fields of Physics, Chemistry, Material Science, Electrical/Mechanical/Chemical Engineering all are involved in the "new" field f nano. Research and development in that area is by its very nature multi-disciplinary, ...
Introduction to Nanometer Scale Science and Technology
This seminar will provide an introductory overview for non-experts of the emerging field of nanometer scale science and technology. The following topics will be emphasized: (1) Historical background and motivation for the study of nanometer scale phenomena; (2) Strategies for controlling the structure ...
Nanotubes and Nanowires: One-dimensional Materials
What is a nanowire? What is a nanotube? Why are they interesting and what are their potential applications? How are they made? This presentation is intended to begin to answer these questions while introducing some fundamental concepts such as wave-particle duality, quantum confinement, the electronic ...
Precipitation Data and Information Services Center
This site contains several sets of precipitation data from NASA Goddard Space Flight Center. Data sources include the Tropical Rainfall Measuring Mission, global precipitation data, and hydrology field experiments. Data sets include real time, monthly or daily global precipitation analyses, precipitation ...
Teaching Biocomplexity in the Geosciences
The emerging field of biocomplexity provides a multidisciplinary approach to looking at complex, interrelated systems. Biological, geological, chemical, physical and human elements are all part of biocomplexity. This site contains a variety of resources for faculty members who teach undergraduate courses ...
General Classification of Igneous Rocks
These lecture notes are part of a series of lectures available on the geology department website at Tulane University. Topics covered include criteria for the classification of igneous rocks, field identification of minerals present in hand sample, thin section examination and chemical analysis. The ...
Metamorphic Reactions, Isograds, and Reaction Mechanisms
These lecture notes cover types of metamorphic reactions. Topics discussed include univariant and divariant reactions, mineral compatibility diagrams (AFM ternary), metamorphic reaction mechanisms, and metamorphic field gradients. The notes contain many ternary diagrams and graphs illustrating the relationship ...
"Relativistic Quantum Field Theory I, Spring 2008"
" 8.323, Relativistic Quantum Field Theory I, is a one-term self-contained subject in quantum field theory. Concepts and basic techniques are developed through applications in elementary particle physics, and condensed matter physics. "
"Doctoral Seminar in Engineering Systems, Fall 2009"
" In establishing the Engineering Systems Division, MIT has embarked on a bold experiment – bringing together diverse areas of expertise into what is designed to be a new field of study. In many respects, the full scale and scope of Engineering Systems as a field is still emerging. This seminar is simultaneously designed to codify what we presently know and to give direction for future development."
