Basic melting temperature The Basic melting temperature widget allows to calculate the melting temperature of a nucleic acid sequence. Gravit Gravit is a gravity simulator. It uses simple Newtonian physics using the Barnes-Hut N-body algorithm. Although the main goal of Gravit is to be as accurate as possible, it also creates beautiful looking gravity patterns. It records the history of each particle so that it can animate and display a path of its travels. At any stage you can rotate your view in 3D and zoom in and out. Gravit uses OpenGL with SDL, SDL_ttf, and SDL_image. Image SXM Image SXM is a version of the public domain image analysis software NIH Image that has been extended to handle the loading, display and analysis of scanning microscope images. Image SXM supports SAM, SCM, SEM, SFM, SLM, SNOM, SPM and STM images. Ohmaid Ohmaid calculates the resistance of a 4 or 5 band resistor based on the color code. A color code chart is included for reference. OpticsCalc OpticsCalc is a handy optical calculator program for everyone from students to engineers who know optical theory, but need a quick and efficient way to perform the calculations. OpticsCalc OpticsCalc is a handy optical calculator program for everyone from students to engineers who know optical theory, but need a quick and efficient way to perform the calculations. Physics 101 SE (commercial) a physics calculation tool, allowing you to focus on physics and not mathematical busywork. Solves for almost any variable in over 80 of the most commonly used physics formulas ProjectileX (commercial) an easy-to-use projectile motion simulator available to students and teachers today. Specifically designed to provide the information that you need to know about a projectile in flight, whether it is an ideal motion projectile or one affected by linear air drag, ProjectileX quickly calculates every detail of its trajectory at the click of a mouse and graphs the projectile's flight path Radiation from a slot in a shield Radiation from a slot in a shield is an EMC tool for worst case estimation of the radiation from an aperture in a shield. ThreeBody ThreeBody illustrates some solutions of the 3 bodies problem in celestial mechanics. WaveMaster WaveMaster is a program that simulates the interference of sinus waves on the water surface. Xphile Xphile is a radiology teaching library allowing browsing by system, pathology, and region. It requires Mac OS X 10.4 or later.
