A free browser-based workspace of physics, chemistry, unit-conversion, and scientific calculators with transparent formulas, explicit units, and worked examples.

Why it surfaced

STEM Hub treats the calculation as something to understand, not just a number to retrieve: its tools show equations, assumptions, and scientific sources, while its guides cover practical traps such as degrees versus radians and scientific notation. The focused library includes equivalent resistance, molarity and dilution, ideal gas law, molar mass, and photon energy.

Ice Does Not Count

August 12’s newborn domains include a rule-bound archive of enormous sodas, 27 family stories cut from one afternoon, a disaster-supply map with a 24-hour freshness rule, and an ocean bell that rings only when six conditions agree.

This is one of 1,000 discoveries in the 2026-08-12 Domain Arrivals issue.
