From elementary school through college, VEXcode is a coding environment that meets students at their level. The intuitive layout of VEXcode allows students to get started quickly and easily. VEXcode is consistent across Blocks and Text, across VEX IQ and VEX V5. As students progress from elementary, middle, and high school, they never have to learn a different blocks, code, or toolbar interface. As a result, students can focus on creating with technology, not trying to navigate a new layout. Drive Forward is the new Hello World We all know that robots attract kids to learn. VEX Robotics and VEXcode are providing opportunities for students of all ages to participate in learning the code that makes these robots work. VEX makes computer science come to life through collaborations, hands-on projects, and engaging experiences. From classrooms to competitions, VEXcode helps to create the next generation of innovators. Drag. Drop. Drive. VEXcode Blocks is the perfect platform for those new to coding. Students use the simple drag and drop interface to create functioning programs. Each block's purpose can easily be identified using the visual cues like its shape, color, and label. We've designed VEXcode Blocks to allow those who are new to robotics to get their robot up and running faster. Now, students can focus on being creative and learning computer science concepts, not stuck trying to figure out the interface. More accessible than ever VEXcode even helps across language barriers, allowing student to read blocks and comment programs in their native language. Drag & Drop. Powered by Scratch Blocks. Students and Teachers will feel instantly at home with this familiar environment. Video Tutorials. Grasp concepts faster. Built-in tutorials cover every aspect needed to get up to speed fast. And more tutorials are coming. Help is always there. Getting information on blocks is fast and easy. These resources were written by educators, in a form both teachers and students will grasp quickly. Drivetrain Blocks. A breakthrough in simplicity. From driving forward, making precise turns, setting speed, and stopping precisely, VEXcode makes it easier than ever to control a robot. Setup your VEX robot. Fast. VEXcode's device manager is simple, flexible, and powerful. In no time at all you can setup your robot's drivetrain, controller features, motors, and sensors. 40+ Example projects to choose from. Jumpstart your learning by starting with an existing project, covering every aspect of coding, controlling robots, and learning to use sensors.

About

Relativity Simulator

Features
Read full description

Relativity Simulator is an interactive relativity toolkit built strictly on the axiomatic foundations of modern physics. There is no "hard sci-fi" here — every result traces back to the Lorentz transformation of special relativity or the Einstein field equations of general relativity, and is verified against numerical truth fixtures. 【Real physics, not imagination】 · 20 interactive modules covering core effects from special relativity to black holes, gravitational waves, and curved spacetime; · Each module ships with precise charts, adjustable parameters, and a "Theory Card" with a fully visible derivation chain; · All demo numbers are recomputed locally on your device from real CODATA constants — nothing is fabricated. 【Phenomena you can verify yourself】 · Gravitational time dilation: why clocks run faster up high — ~80 ns/day faster atop Everest, ~38 µs/day faster on GPS satellites; · Twin paradox: fly to 4.22 light-years at 0.8c and the Earth twin ages 10.5 years while the traveler ages only 6.3; · Tidal disruption: why you get stretched into "spaghetti" falling into a black hole — small holes tear you outside the horizon, supermassive ones only after you cross it; · Plus light bending, gravitational lensing, the Schwarzschild horizon, frame dragging, and mass–energy equivalence E=mc². 【Built for learning and teaching】 · Volume-based progression: kinematics → gravitational field → black holes → cosmology → applications; · Bilingual (zh/en) system notes ship with every effect: derivation, physical quantities, and references; · Chinese / English UI follows your system language. 【Privacy first】 The app collects, stores, and transmits no personal data, embeds no third-party SDKs, and runs every computation locally on your device. Whether you are studying, teaching, or simply curious, Relativity Simulator lets you actually run the "invisible spacetime" and watch it.

Verdict

The call

VEXcode V5 and Relativity Simulator are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
