5000 free math, physics, and engineering video tutorials and lectures
Here are the collections of sites with math, physics, engineering, and other sciences video tutorials. Some sites also contains non-science videos as well. If you find a site with more than 50 videos, please inform me so I could include it on the list. Khan Academy – more than 2100 2600 not only for math but also includes other subjects such as economics, chemistry, physics and other fields.

Free online Multimedia Training Videos from the University of Westminster Math Apps for the iPhone, iPod Touch, and iPad Yesterday, while browsing through the app store on iTunes, I came across a banner-style ad at the top of the page for apps that help you to learn math. I found this feature very helpful and decided to browse through some of the apps. The topics were broken down into sections including Numbers & Operation, Geometry, Algebra, Calculus, Probability & Statistics, Applying Math, and Math Games. The important factors that you should consider when buying an app to use is price, quality, interactive ability, and be sure that it is engaging and easy to use. iLiveMathSpeed iLiveMathSpeed is one of a series of iLiveMath apps provided by iHomeEducator. If they want to learn more about a topic, they are able to choose to go through to a kid-friendly browser that links to the terms based on the transportation and math covered the program. The newest version of this app has larger buttons to pick the various options and answers in the activity to help special needs students. 115-in-1 Math Solver

Storyboarding: Pre-Writing Activity  The more we podcast and have our students create video clips or other digital storytelling projects, the more we need to teach storyboarding as part of the process. Being able to pre-visualize how your story will unfold is becoming a vital skill to have for storytellers. Storyboards are defined as: Graphic organizers such as a series of illustrations or images displayed in sequence for the purpose of pre-visualizing a motion picture, animation, motion graphic or interactive media sequence, including website interactivity. In the book by Roger Essley “Visual Tools for Differentiating Reading & Writing Instruction: Strategies to Help Students Make Abstract Ideas Concrete and Accessible”, he says Storyboarding, or picture writing, is the origin of all written languages, used by ancient cultures before text evolved and as a natural bridge to text. Pre-Writing is defined as Pre-writing is the first stage of the writing process, typically followed by drafting, revision, editing and publishing.

Professional blog | 21st Century Educator Here are some tools which I've either used (or explored) for mathematics education. They aren't all open source, but they are all extremely useful, and they are all free to use (free as in free beer, some of them are also free as in free speech). Geogebra This program lets you explore algebra and geometry, much like it's proprietary cousin, Geometer's Sketchpad. Mathematics Visualization Toolkit The Mathematics Visualization Toolkit is exactly that, a program which lets you visualize mathematics. Scratch Scratch is an excellent program for learning programming but also mathematics like variables, sequences, Cartesian coordinates, and other useful mathematical concepts. Netlogo Netlogo is "a multi-agent programming modelling environment" (According to the Netlogo website). Audacity Audacity is an open source audio editor and recorder. Calculize Calculize is a free (currently) web app which lets students perform mathematical computations using a reasonably simple programming language. Desmos Logo

High-resolution 3D Models of Cities Created from Aerial Photographs If you thought Google Earth was cool, check out the work being done by Swedish corp C3 Technologies. Using only photos shot from planes, they can automatically create high-resolution 3D models of entire cities that can then be explored. The above video shows a beautiful fly-by of New York City. All of the C3 products are based on high-resolution photography captured with carefully calibrated cameras. They can also apply the technology to turn panoramic photographs captured at street-level into 3D models of the scene that the user can navigate through freely. (via Photoxels)

How to Create Stop Motion Videos - free stop motion software, dragon stop motion alternative, stop motion pro,stop motion maker Stop motion or Stop action is an animation technique used to make a physical picture (images) to move on its own (videos). So there by converting all fixed pictures and bundle them to create an action videos. You can easily create stop motion videos for free with the stop motion software named Jellycam. You might have watched many stop motion youtube videos on clay animation. There is a famous stop motion software ‘Dragon stop motion’ animation software tool for Mac OS X and Windows. But there is only free trail available. JellyCam is a stop motion maker that can make stop-motion films with a web-cam or a bunch of photos. Wondering how would it be ? Once you’ve installed the JellyCam (remember, its an adobe air app, so get yourself air app installed before you install jellycam), open the jellycam and it automatically startsup the webcam which is installed in your computer.

The How-To Geek Guide to Audio Editing: Cutting, Trimming & Arranging Audacity novices often start with lofty project ideas, but sometimes they lack the basics. Knowing how to cut and trim tracks is basic audio editing and is a fundamental starting point for making more elaborate arrangements. For this exercise, I’ll be making a ringtone from a Castlevania: Symphony of the Night track. I have the original CD and used that so I started with better quality audio than an MP3. You can follow along with any file you like, just so you get a feel for cutting, trimming, and arranging sound clips for yourself. I know which parts I want to edit in the track, but a quick play-through will help me look for those areas visually. The scrubber in the above screenshot is pointing to a lull in the music, where the audio drops low or fades out. First, let’s make sure the Selection tool is active. Next, let’s make a selection in an area of the track where we want to make an edit. I know that the song changes somewhere in here. That’s much better, isn’t it?
