Top 10 Universities With Free Courses Online #1 UC Berkeley Ranked as the #1 public school in the United States, Berkeley offers podcasts and webcasts of amazing professors lecturing. Each course has an RSS feed so you can track each new lecture. For printable assignments and notes you can check the professors homepage, which is usually given in the first lecture or google his name. Even though the notes, homework and tests are not directly printed in the berkeley website, as they are in MIT and other courseware sites, it's not a problem to find them.

chemistry - dawnwelch7 Introductory Activity Rubric Matter and Its Changes - StumbleUpon Spring 1995 A number of descriptive and prescriptive design methodologies have been developed for general engineering design problems, i.e., product design [Pahl 1984, Pugh 1990, Ullman 1992, Ulrich 1994, Asimow 1962]. While these methodologies are applicable to different types of design (adaptive, variant, etc.), they tend to emphasize design problems that seek "original solutions." This emphasis provides a sound foundation for teaching engineering design; it also provides a foundation for establishing corporate design processes in industry. However, for the class of problems known as redesign (adaptive, variant, etc.), an emphasis on original design may be too general as a problem solving approach. Sferro, Bolling, and Crawford argue the legitimacy of this claim, based on an analysis of the current variant design processes in the automobile industry [Sferro 1993].

20 Places to Find Free Books Online The following is a guest post by Bailey Harris. There are many different sites offer free books online. Within minutes, you could find enough reading material in the form of e-books and audio books to keep you and your family entertained for months, if not years. The following sites provide free books that can be enjoyed online, downloaded to your computer, or transferred to an e-reader or MP3 player. Chemistry Review Activities I re-organized the course during the 2014 - 2015 school year. Some review activities were moved to new units. This has resulted in a change to some of the file names, so direct links to the individual activities may need to be changed. These are not graded assignments. They are intended only as practice of concepts and vocabulary that are essential to your success in this course.

Adaptive Frequency Oscillators Adaptive frequency oscillators Our first attempt toward adaptive dynamical systems was to develop the concept of adaptive frequency oscillators, which are oscillators that can adapt their parameters to learn the frequency of any periodic input signal. It means that they change their parameters in order to have an intrinsic frequency that corresponds to the frequency of the input.

Database of Periodic Tables There are hundreds of periodic tables in web space, but there is only one comprehensive database of periodic tables & periodic system formulations. If you know of an interesting periodic table that is missing, please contact the database curator: Dr Mark R Leach. Harrington Periodic Tables So we start this effort tabula rasa (without preconceived ideas). Chem_Sim Chemical reactions are often modeled as continuous differential equations with reaction rates related to chemical concentrations (law of mass action). As many have pointed out (e.g., Gillespie, Lok, Salwinski and Eisenberg, or Keane, reactions actually occur as discrete events involving molecules. The reaction has some probability of occuring, but either occurs, or does not. Thus we replace concentrations with counting individual molecules and differential equations with rolling the dice to see if a reaction occurs. For a bimolecular reaction involving two molecules A and B, with concentrations [A] and [B] and a rate constant K, the probability of the reaction occuring (from mass action) will be K[A][B] .

The Online Learning Blog from Study2U Supposedly browsing the internet requires more brain power than watching television. Although judging from some of the websites we’ve come across that assumption is cast into doubt. Here’s some of the sites we like that might get your brain to sit up and listen. Ted A conference that started in 1984 bringing together experts in technology, entertainment and design quickly grew into so much more.

Application of the Scientific Method Backyard Brains » Working RoboRoach Prototype Unveiled to Students of Grand Valley State University We’ve been busy in the trenches of our R&D department designing a working prototype of the “RoboRoach,” a remote control system to enable left and right turning in running cockroaches. This began as a University of Michigan Senior Engineering Project we sponsored in Winter 2010, and over the past year we’ve incrementally been working to improve it, especially after getting great feedback from our colleagues at the latest Society for Neuroscience conference (thanks Cindy). By taking the small, lightweight control circuitry out of the toy “HEXBug Inchworm” and modifying it with low-power 555 timer chips to create biphasic pulses, we can deliver 55 Hz stimulation to the antennae nerves of large discoid and fuscia cockroaches. We gave a seminar recently on Feb. 25th to the undergraduate students at Grand Valley State University (thanks for the invite John and Merritt!), and we publicly unveiled a working prototype!

Teach yourself to program We are entering the summer, the perfect time to improve yourself, you could go running or swimming, you could learn a new foreign language or perhaps you could learn to program. Self-learning is not as hard as it sounds, and it’s much easier than self-learning Spanish or French. There are really wonderful sources to start learning these new languages, understanding the concept behind programming and giving it a try with some interesting problems. Basic Programming
