Before you can design for screens, you need to understand how screens work. This course starts with the web stack — HTML structure, CSS styling, JavaScript behavior — then builds up to design principles grounded in human perception. Every rule exists because of how humans see, think, and feel. You'll learn the code that makes it happen alongside the psychology that makes it work.
Every plugin is just the same principles, reorganized. Once you understand what frequency, amplitude, and harmonics are — how filters, envelopes, and modulation work — opening any new synth or effect becomes just finding where they put the controls. The principles are universal. The interfaces change.
Statistics makes sense when you can drag the data points and watch the numbers change. This isn't a textbook — it's 19 interactive modules where you manipulate distributions, slide confidence intervals, and feel what variance means. Every concept has a visualization you can touch.
Languages aren't just different vocabularies — they're different ways of organizing reality. Some have 5 grammatical cases, others have 15. Some mark evidentiality (how you know something), others don't. This visualizer places languages on continuous spectrums, revealing patterns invisible in textbooks.
Most language apps teach you to translate. This one teaches you to think in Vietnamese. Built for heritage learners, second-generation speakers, and curious beginners — 130+ lessons organized in 5 layers, from tones and syllables to full conversations. No romanization crutches. Real Vietnamese from day one.
Pali is not just an ancient language — it's the direct gateway to the Buddha's words as preserved in the Theravada tradition. This course takes you from alphabet to suttas, with the same layered approach: see the grammar, understand the patterns, read the original texts.
