Nous: Strange History & Ideas

Flirpz

About this app

History is stranger than the textbooks let on. Nous is a learning app for the odd, overlooked and genuinely surprising side of history, religion, science and philosophy, written from mainstream scholarship.

Find out what "cargo cults" really were, and where the label came from. How an island that does not exist stayed on digital maps until 2012. Which Christianities lost out before there was an agreed Bible. Why the world kept not ending, and what believers did next.

WHAT'S INSIDE
• 16 subjects and 248 topics, from Sacred Forgeries and Strange Saints to Number Stations, Undeciphered Scripts and Forgotten Empires
• Over 1,500 short lessons and nearly 10,000 quiz questions, with explanations
• The big questions: what the universe is made of, how life began, what a mind is
• The core subjects too: physics, biology, chemistry, mathematics, economics, literature and more

HOW IT WORKS
• Lessons take a few minutes. Guess first, then learn why.
• Every answer is explained, and a review queue brings back what you missed
• Hands-on simulators: particle sandbox, molecule builder, evolution simulator, deep time scroller, era map
• A knowledge graph shows how every topic connects
• A daily pick, a daily challenge and a fortune cookie from the subject you're studying
• Streaks, XP and ranks, if you like that sort of thing

STRANGE, NOT MADE UP
Legends are labeled as legends, debates are shown as debates, and the evidence comes first.
