Google Body - Google Labs. Detexify LaTeX handwritten symbol recognition. Want a Mac app?
Lucky you. The Mac app is finally stable enough. See how it works on Vimeo. Download the latest version here. Restriction: In addition to the LaTeX command the unlicensed version will copy a reminder to purchase a license to the clipboard when you select a symbol. You can purchase a license here: Buy Detexify for Mac If you need help contact mail@danielkirs.ch. What is this? Anyone who works with LaTeX knows how time-consuming it can be to find a symbol in symbols-a4.pdf that you just can't memorize. How do I use it? Just draw the symbol you are looking for into the square area above and look what happens! My symbol isn't found! The symbol may not be trained enough or it is not yet in the list of supported symbols. I like this. You could spare some time training Detexify. The backend server is running on Digital Ocean (referral link) so you can also reduce my hosting costs by using that referral link.
Why should I donate? Hosting of detexify costs some money. Flying Pig. Free Children’s Videos and Activity Idea Videos for You by Cullen’s Abc’s. Science Tube. Physics Flashlets. Michael Fowler See also our Applets!
This is a collection of Flash animations to make learning physics easier! They were created by myself and my students Jacquie Hui Wan Ching and Heather Welch, and Michael Timmins and , in the summer of 2003. Some of these flashlets are not quite perfect yet, but we’re working on it. They do of course require you to have a Flash player on your machine. Pythagoras: prove Pythagoras’ Theorem fast by moving triangles around with your mouse. Eclipse of the Moon: a short movie of the Moon moving through the Earth’s shadow, and how it appears from Earth. Ptolemy's Epicycles for Inner Planet Motion: actually a simplified version, with just the basic epicycle idea illustrated.
Ptolemy's Epicycles for the Outer Planets: again, just the basic epicycle idea. Earth-Mars Line of Sight in Two Models. Kepler’s Laws: construct your own planetary orbits and check Kepler’s Laws! UVA Virtual Lab: Homepage. Physics - Applets and Animations. Physics Flash Animations. We have been increasingly using Flash animations for illustrating Physics content.
This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing. Also included is the minimum version of the Flash player that is required; the player is available free from The categories are: In addition, I have prepared a small tutorial in using Flash to do Physics animations. LInks to versions of these animations in other languages, other links, and license information appear towards the bottom of this page.
The Animations There are 99 animations listed below. Other Languages and Links These animations have been translated into Catalan, Spanish and Basque: En aquest enllaç podeu trobar la versió al català de les animacions Flash de Física. Many animations have been translated into Greek by Vangelis Koltsakis. Algodoo. Physics and Flash. Flash is well-known for producing spiffy animations.
Not as well-known is how to use it for demonstrations in the sciences using proper mathematical equations to control the motions. Using proper Physics equations for animations is also useful for realistic games. This small document is a tutorial in exploiting the capability of using equations to control animations. I assume that you already know at least a little about using Flash, and have at least a rudimentary knowledge of ActionScript. We will create 5 different animations below. When this document was written, the current Flash program was MX 2004. The Undamped Harmonic Oscillator We will use a harmonic oscillator, such as a mass oscillating on a spring, as our example.
A is the maximum amplitude of the oscillation. (pronounced omega naught) is the "natural" angular frequency of oscillation, and depends on the mass and the particular spring. t is the time. In this document we will be clever and choose the phase angle to be zero. Chemicalize.org. Stellarium.
