Atom Worldbox vs Visual Neuroscience Anatomy

The entire periodic table is yours to play with. Drop atoms onto the screen, watch them bond into real molecules, and trigger genuine chemical reactions all driven by real science, not scripted animations. Atom Worldbox is an open-ended chemistry and physics sandbox. There are no levels, no goals, and no rules just a living world of atoms governed by the same forces that shape the real universe. Bring two elements together and see whether they bond. Build a known molecule and the app recognizes it instantly. Push reactive elements together and watch reactions ignite, transform, and settle on their own. WHAT YOU CAN DO • Experiment with every element on the periodic table • Watch atoms form covalent, ionic, and metallic bonds based on real chemistry • Build molecules and see them automatically identified • Trigger authentic chemical reactions and watch them unfold naturally • Turn on Thermal Mode: heat and cool your world — condense gases into droplets, boil them, or fuse hydrogen at star-core temperatures • Explore radioactivity, isotopes, and natural decay • Set off chain reactions and watch them cascade across your world • Zoom, pan, and arrange everything with simple, intuitive touch controls REAL SCIENCE, NOT SPECIAL EFFECTS Every bond and reaction is calculated from real chemical and physical principles. Atoms attract and repel, electrons transfer, and molecules come together exactly the way they would in nature. It's a living simulation you can build, break, and rebuild as many times as you like. GREAT FOR • Curious minds who love to experiment and explore • Students discovering chemistry and physics • Teachers looking for an interactive way to show bonding and reactions • Anyone who loves satisfying, science-driven simulations Works fully offline. No account required, no clutter—just open it and start building. Atom Worldbox is free to explore. Upgrade to Pro to unlock the complete sandbox experience.

Visual Neuroscience is an interactive 3D atlas of the human brain, built for anyone learning neuroanatomy without a lab or a licence. Turn a real MNI152 brain, tap through its regions, search Brodmann areas by what they do, follow the white-matter tracts, go down to the cell and the molecule, and see published studies drawn on the scan itself. Everything ships inside the app and renders on your device, so it works on a train, at the back of a lecture theatre, or in aeroplane mode. WHAT IS INSIDE • 3D Region Atlas: the MNI152 template with the AAL-116 parcellation. Pick any region, highlight it in three planes and in 3D, and read what it does. • Brodmann Area Atlas: the classic cortical map, both faces of the hemisphere on one screen beside the brain in 3D. Tap any area to read what it does. • Tractography: the HCP1065 whole-brain tractogram. Rotate it, slice it, follow the bundles. • Receptor density: where the major neurotransmitter receptors sit, from published PET and autoradiography, with a source behind every number. • Network Atlas: the brain's large-scale networks in six states, from flow to meditation. • Microanatomy: a neuron drawn part by part with a quiz to learn it, the neurotransmitters as chemists draw them, and a hundred and fifty receptors, channels and transporters with the drugs that act on them. • Molecular: the dopamine and serotonin receptors in 3D, from experimental structures. Watch the neurotransmitter dock, see where antipsychotics, triptans, LSD and psilocin sit in the same pocket, and compare the subtypes. • Visualising Studies: published papers drawn onto the scan, beginning with a study of auditory hallucinations in schizophrenia. • Digital Textbook: OpenStax's Introduction to Behavioral Neuroscience in full, nineteen chapters, with every figure and reference. • Practice: adaptive questions that score as you go, lean toward what you keep getting wrong, and explain every answer. The first bank follows the KCL MSc Neuroscience syllabus. AI CONNECTOR Use the MCP server with your AI of choice. Any assistant that supports the Model Context Protocol can ask the atlas what a region does, where a receptor is densest or how the brain changes in a state; each answer links to the view it describes, and the About tab shows how to connect. MADE FOR TOUCH, AND FOR A DESK Pinch to zoom on every scan and diagram, two fingers to pan, one to rotate; on a Mac the same works with a trackpad. Save a view as a picture, or the brain as a 3D model to open in your room. AN ACCOUNT, ONLY IF YOU WANT ONE Sign in with Apple, Google or email to keep your practice progress and saved models across iPhone, iPad, Mac and the web. Nothing requires an account, nothing is sold, and there is no advertising and no tracking. Delete the account from inside the app at any time. BUILT ON OPEN DATA The MNI152 template, the AAL parcellation, the MRIcron Brodmann atlas and the HCP1065 tractogram, rendered with NiiVue; receptor structures from the Protein Data Bank. Each page says where its data came from and where the evidence stops. Brodmann Areas diagram adapted with permission from IFEN – Institute for EEG-Neurofeedback / Neurofeedback Academy. WHO IT IS FOR Students revising between lectures. Lecturers who want a live brain on the screen instead of a slide. And anyone who wanted to study this and was priced out. Built by one developer, with a post-grad in Applied Neuroscience from King's College London Online and experience in software development, so that the next generation of neuroscientists and psychologists has a map of the brain that is easy to use and understand. The website and the app share the same code and the same author. If something is missing for your course, write, and it usually ships within the week. Not a medical device and not a diagnostic tool. An educational reference that summarises published work and draws published atlases, with its sources on every page. Also on the web at visualneuroscience.ai
