Charged Physics Lab vs Fly Brain

Charged Physics Lab turns the Physics I and Physics II formula sheet into an interactive problem-solving workspace. Start with the language in a homework problem, a quantity you need, or a formula you recognize. Search across 200 equations or browse the Formula Map by physics section. Open a formula to see its variables, fixed units, physical meaning, and a diagram that responds to the values in the equation. The equation itself is the calculator. Tap a variable tile to enter a value. Hold a tile to isolate that variable automatically, or use a short hold and swipe to make one inverse algebra move yourself. When every required value is known, the result appears immediately. For multi-step problems, carry a solved quantity into a related formula and keep the calculation on the same working blackboard. Formula search surfaces useful next equations when a result can feed another step. Teacher-style worked examples combine the physical story, a labeled visual, symbolic rearrangement, substitution, units, and interpretation. Narration and the visual presentation move together so you can follow the reasoning instead of only seeing a final answer. Included: • 200 Physics I and Physics II equations • Plain-English, symbol, quantity, and topic search • Interactive variable tiles with fixed units • Automatic isolation and step-by-step algebra gestures • Live diagrams and variable explanations • Narrated worked examples • Multi-formula problem chains • A built-in How to Use guide • On-device progress and settings • Core learning content available without an internet connection Charged Physics Lab is a learning and calculation aid. Always use the assumptions and sign conventions appropriate to your course and problem.

A fruit fly, with its brain on show. Watch its nervous system light up in real time as it sees through your camera, listens through your microphone and responds to touch and motion. What it senses • Wave a hand or finger in front of the camera and its optic lobes light up, each eye from its own side. • Talk, clap or play music and the hearing centre in its brain flares up. • Turn your phone and its balance organs light up. • Tap one of its legs and a signal runs up that leg's own nerve. Tap its body and it shudders. How it behaves • Talk to it, or make a loud noise, and its wings buzz. • Show it a strong colour, like a piece of fruit, and it sets off walking. • Move something suddenly in front of the camera and it freezes with caution. • Bring something quickly towards the camera and it gets frightened and tries to escape. • Leave it alone for a while and it stops to clean itself. Inside its head The brain is built from real measurements: 34 regions in their measured shapes, drawn in over 3,000 points of light, and more than 500 real neurons traced from electron microscope images, each along its own path. Open the brain view to see 12 regions named, then pinch right in until the lobula plate splits into its four layers. The shapes and the neurons are real. The activity is illustrated, not recorded. On your table Tap AR to put the fly in your room. Pinch it from 5 cm to 20 m long and walk all the way around it. Make it yours Pick from eight skins, or go see-through and watch the brain light up inside the head. Private The camera and microphone are optional, and nothing they pick up is recorded, stored or sent anywhere. No ads, no accounts. Brain region shapes and neurons are based on public data from Janelia's FlyEM project and the Male CNS team (HHMI Janelia, the University of Cambridge, the MRC Laboratory of Molecular Biology and Google Research), used under CC BY 4.0.
