A Workshop Summary to the Chemical Sciences Roundtable. A group of chemists, chemical engineers, and others from academia, government, and industry participated in a workshop sponsored by the Chemical Sciences Roundtable to explore how bioinspired chemistry can help solve some of the important energy issues the world faces today. The workshop featured presentations and discussions on the current energy challenges and how to address them, with emphasis on both the fundamental aspects and the robu more...

MIT Open Courseware (OCW) is a web-based publication of virtually all MIT course content. OCW is open and available to the world and is a permanent MIT activity.

This Open Educational Resource is hosted by Archive.org OER section. This is an 18-lecture series on Image Processing that the author, Alan Peters, has created over the past 9 years (1999-2007) for his course, EECE/CS 253, at Vanderbilt University. The files are all in Adobe Acrobat (.pdf) format and MS Powerpoint (.ppt) format. The files are quite large because of the images in them. The topics covered include: Image Enhancement by Point Operations, Color Correction, The 2-D Fourier Transform a more...

This online full course published by MIT under Creative Commons License concentrates on special relativity and is normally taken by physics majors in their sophomore year. Topics include Einstein's postulates, the Lorentz transformation, relativistic effects and paradoxes, and applications involving electromagnetism and particle physics. This course also provides a brief introduction to some concepts of general relativity, including the principle of equivalence, the Schwartzschild metric and bl more...

The "Adventure of Physics" is a free book introducing modern physics. All chapters are available for download. It is written to be simple, vivid, and challenging on each of its 1300 pages. It covers mechanics, thermodynamics, special and general relativity, electrodynamics, optics, quantum physics, nuclear physics, elementary particle physics, and unification.

This full online course published by the University of Colorado is being part of a series related to Physics Education Technology (PhET). Abstract: A realistic mass and spring laboratory. Hang masses from springs and adjust the spring stiffness and damping. You can even slow time. Transport the lab to different planets. A chart shows the kinetic, potential, and thermal energy for each spring. This interactive course is available in Flash format (swf).

This course available under Creative Commons licence is provided by connexions.org and contributed by Rice University. It is a full online course divided into sections composed of small modules. It is an introduction to "solid state device inclusing field effect and bipolar transistors. Properties of transmission lines and propagating E&M waves."

Like for other courses proposed by connexions.org, modules are also available at their own or as elements of other courses. The sections are div more...

This Course is published under the Creative Commons Licence on the cnx.org Web site. Summary: For middle school to adult, an explanation of the relationships between frequency, wavelength, and pitch.

Any sound that you hear as a tone is made of regular, evenly spaced waves of air molecules. The most noticeable difference between various tonal sounds is that some sound higher or lower than others. These differences in the pitch of the sound are caused by different spacing in the waves; the clo more...

A site that uses the principles involved in the design of a roller coaster to teach physics concepts. In addition to the information, some sections use the Roller Coaster Simulator, RCS, to increase the understanding and the application of the principles discussed. Also states what background knowledge is necessary to understand the upcoming information. An introductory section explains the difference between the principles of velocity and acceleration, and other parts of the site include labs, more...
