QM Eigenstate Superposition Demo Model
The EJS QM Eigenstate Superposition Demo model displays the time dependence of a variety of superpositions of energy eigenfunctions for the infinite square well and harmonic oscillator potentials. One of the eleven pre-set superpositions can be selected via a drop-down menu with the resulting wave function shown in phase-as-color representation. A table of the expansion coefficients is shown and can be edited. The width of the infinite square well potential can be changed via a slider.

Forces and Graphing
This activity can be used to explore forces acting on an object, to practice graphing experimental data, and/or to introduce the algebra concepts of slope and intercept of a line. A wooden 2x4 beam is set on top of two scales. Students learn how to conduct an experiment by applying loads at different locations along the beam, recording the exact position of the applied load and the reaction forces measured by the scales at each end of the beam. In addition, students will analyze the experiment d
Multiple Sclerosis - Station and Gait Exam - Station Sub-exam - Patient 18
Ed is a 57-year-old Caucasian male with a 15-year history of neurological disability that was diagnosed after his initial attack as multiple sclerosis. Lumbar puncture demonstrated the presence of numerous oligoclonal bands and MRI later showed multiple white matter plaques. He suffers from a significant dysarthria, as well as tremor and ataxia.
Myotonic Muscular Dystrophy - Cranial Nerves Exam - Spinal Accessory (CN XI) Nerve Sub-exam - Patien
Patient is a 52-year-old African-American male with a known diagnosis of myotonic muscular dystrophy. His neuromuscular symptoms began in the early 1990s with poor dexterity in the hands, dropping objects, and clumsiness with fine motor weakness. He is very slow buttoning clothes, putting on his shoes, brushing his teeth, shaving, and other similar activities. He has trouble in ambulation and falls frequently. He has trouble getting up from a chair or sofa and climbing stairs. He also reports co
1.9 Summary and conclusion: ‘take-away messages’
Are you about to undertake a PhD in science, technology or mathematics? If so, this unit will help you to examine your work processes. You will consider and develop the nature of postgraduate work and look at the planning of work needed at doctoral level.
In this unit you will see first how to convert vectors from geometric form, in terms of a magnitude and direction, to component form, and then how conversion in the opposite sense is accomplished. The ability to convert between these different forms of a vector is useful in certain problems involving displacement and velocity, as shown in Section 2, in which you will also work with bearings.
Measuring Community Structure
A plant community can be sampled using a "wandering quarter" survey, a plotless survey method that requires no set-up and minimal equipment. Participants zig-zag from tree to tree, always heading in the same general compass direction. Data collected can be used to calculate several common measures of plant community structure, including species richness, species diversity, relative basal area, stems per hectare, relative dominance, and importance value. Hypotheses about the effect of various abi
"In the Shadow of Society": Migrant Workers and Unionists Urge Congress to Enact Effective Federal F
In the early 20th century, large-scale commercial agriculture displaced family farms, tenant farmers, and sharecroppers. Hand labor, however, remained more cost effective for harvesting certain fruits and vegetables. Farmworkers under this new system were hired only for seasonal work and had to travel frequently. The migratory experience left these workers--primarily Mexicans, Mexican Americans, African Americans, Puerto Ricans, and Filipinos÷permanent outsiders and vulnerable to exploitation,

"Dynamic Optimization Methods with Applications, Fall 2009"
"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 c
ISKME's Sun Curve Design Challenge Project Wiki Page
This wiki page documents the Sun Curve Design Challenge, inspired by the "Sun Curve" aquaponic garden sculpture to challenge teachers and students to produce new OER materials and incorporate green design thinking into the classroom.

Different plants produce different leaves
Plants produce leaves to gather sunlight and exchange gases in the environment around them. Plants produce leaves unique to that particular plant species. Leaves can have many different shapes, sizes, and colors.
