Six laboratory experiments. All of them have been rewritten from scratch in JavaScript: they work in any browser and on a phone, and nothing needs to be installed.
Under each one the original has been kept — the very Flash in which the experiments were made at the end of the 2000s. It is played by Ruffle, a Flash emulator built in WebAssembly; it weighs fourteen megabytes and loads only when you press the button. This is emulation and not Flash: the old experiments may not start completely, may run slowly, or may show something other than what they showed fifteen years ago. The originals are kept for comparison, not for use.
