Solar Coaster vs Engineering & Tech Animations

Solar Coaster provides accurate position, time, motion and eclipse information for Earth's nearest star, Sol, our Sun, and nearest celestial body, Luna, our Moon. Information includes 3D movement graphs, upcoming eclipses and their circumstances, rise and set times, positions, distances and velocities, moon phase, illumination and crescent rotation. Solar Coaster automatically updates its state every minute, or you can examine minutes randomly. The simulation uses a local horizontal coordinate system when displaying information, which essentially means that your current position is the center of the Universe and all calculated values are relative to you. Sun and Moon positions are also available in equatorial coordinates. Solar Coaster stores enough onboard astronomical data to keep it running through the year 2100 AD, which means that all calculations can be performed locally without the need of a network connection — useful while in the wild chasing an eclipse. Algorithms are accurate at all longitudes, and latitudes between -61° south and +60° north (roughly speaking, locations outside the Polar regions). Of course, you must have Location Services enabled and allow Solar Coaster to access your position for accurate simulation results, and to properly detect eclipses visible at your location. You can also allow Notification Center to keep you informed when those eclipses will occur. Solar Coaster comes in various flavors: for iOS a native App; and for macOS a native App, Screen Saver and Web App.

Science Animations: Engineering and Technology animations is for learners in technical high schools as well as first year engineering students. This app will help them to get a better understanding of basic concepts in engineering. The concepts are explained in a visual, dynamic and interactive way. This app does not replace the teacher/lecturer or handbook but is a valuable additional source for teachers/lecturers. It is also important that learners should play on their own with this app. Topics covered by the app include the following: Force, Frameworks and Acceleration; Stress, Pressure and Bending Moment; Vibrations; Alternating Current; Thermodynamics; Bernoulli's Principle; Cubic Crystal Structures; Phase Diagrams; Orthographic Projections; Gears; and Engines.
