Loughborough Wave Lab vs Henceforth

Loughborough Wave Lab is an educational learning app designed to aid students in their understanding of electromagnetic wave concepts in an engaging and entertaining way! Features include: • Virtual pond • Persistent Sinusoidal Pulses • Virtual Ripple Tank • Waveguide Simulator • Young's Double Slit Experiment • Custom Simulation Mode Loughborough Wave Lab is intended to accompany teaching on Electromagnetic phenomena and to provide students with an interactive way of seeing these principles in action! Educators can now author their own custom simulation files, upload them to a web server and then have Loughborough Wave Lab execute the simulations using a WiFi or cellular data connection to download the configurations and display them to the user. This uses the new, open-source configuration standard CEML which has been introduced by the developer (available at www.github.com/danielrbrowne/CEML)

Bitcoin you can script. Henceforth is a Bitcoin SV wallet wrapped around a complete FORTH terminal. Send, receive, and broadcast real Bitcoin transactions from a programmable command line. Define your own words, build raw transactions byte by byte, and visualise data with code you write yourself. There's nothing else like it on the App Store. YOUR KEYS, YOUR COINS Private keys live in the iOS Keychain — never on a server. Every send is gated by Face ID or Touch ID. Transactions are permanent on the BSV blockchain, and fees are typically a fraction of a cent. For extra safety, Cold Mode signs transactions on a second offline iPhone over AirDrop — a real air-gap setup without dedicated hardware. A TERMINAL THAT DOES MORE THAN PRINT HELLO WORLD Full Forth-2012 CORE compliance (133 standard words) inside a vocabulary of 384 words, 173 of them Bitcoin Script and Bitcoin SV protocol words, 120 of those opcodes. Print a string: ." Hello, World" Define a word and run it: : square dup * ; 5 square . Pay someone from the command line: 1000 s" 1Q88RPbg..." send The terminal isn't a toy shell — it's the same Forth interpreter that builds the transactions you broadcast. WRITE, SAVE, AND RUN YOUR OWN PROGRAMS Save reusable code as .fs files. The built-in editor and file manager lets you write, version, and rerun scripts. The classic FORTH way: small composable words growing into your own personal vocabulary. CHARTS FROM THE STACK Bar, line, and pie charts from any values on the stack. Visualise sequences, payment histories, or whatever data you compute — directly from FORTH code. WHAT'S INSIDE • BSV wallet with multi-recipient sends and raw transaction builder • Privacy-aware UTXO selection — fresh change addresses every send • 1Sat Ordinal awareness — protects your inscriptions from accidental spending • SPV transaction verification — trust math, not servers • Universal app — iPhone, iPad, and Mac • Local-first — works offline; on-chain when you broadcast • Forever yours — one-time purchase, no subscriptions, no ads Powered by FORTH, the stack-based language Chuck Moore created in 1970.
