NewtonDV vs vDiffraction

Just imagine you want to find out which forces have an impact on a bungee jumper. Or whether the amount of fun you have on a roller coaster differs depending on sitting in the first or the last car. Maybe you want to get to the bottom of the moon landing in 1969. Did it really take place or are the videos just fakes produced in a film studio somewhere on our planet as alleged by several obscure sources? These and other questions about kinematics can be answered easily with NewtonDV. The app analyses the movement of persons or objects in a video using mere physics. All you need is a given film sequence — or record your own video with NewtonDV. Range of functions: - Recording HD and slow-motion videos using the built-in iPad camera (up to 240 fps) - Importing videos from the photo library, Files app, iCloud Drive, or via AirDrop - Rotatable coordinate system for inclined planes or rotated recordings - Displaying measurement data in tables and diagrams - Drawing trend curves - Creating time strips and stroboscopic images - Displaying velocity and acceleration vectors with numerical values - Exporting tables and diagrams as png files - Exporting measurement data as csv files for further analysis in a spreadsheet program - Sharing tables and diagrams via email - Printing tables and diagrams - Light and dark mode

This game is a fun way to discover the world of crystals and their symmetries through diffraction. Crystals are all around us: in our environment (rocks and minerals, etc), in our bodies (sugar, bones, gallstones, etc.) and in technology (metals and alloys, silicon and quartz used for microelectronics, etc.). By successively discovering the diffraction of X-rays, neutrons and electrons, scientists in the twentieth century threw the door to the microscopic world wide open by demonstrating that crystals are made ​​up of atoms and molecules and explaining their structure. Crystals are characterised by the fact that their constituents are arranged in a highly ordered structure. This internal order and its symmetry is clearly visible in the diffraction patterns produced by any crystal. It is this symmetry which is also gives crystals their often amazing shapes, making them highly prized by rockhounds. Whether you are a senior scientist, a student, or just curious about science, vDiffraction is a serious game that will let you try your hand at crystal diffraction so that you can begin to understand how scientists identify the symmetry characteristics of a crystal. This is the first, crucial step towards understanding the atomic and molecular structure of a crystalline material, in other words what type of atoms and molecules make up the crystal and how they are organised.
