An on-device workbench for volcanology and sedimentology students to analyze sieve data, calculate Folk & Ward statistics, and export worksheets without spreadsheets or network access.

Why it surfaced

This is an unusually specific tool: users assemble ASTM-style sieve stacks, enter retained mass, compare up to three sample curves, and inspect phi-to-millimetre conversions. Its promise to let an undergrad lab “finish before the period ends” gives the otherwise technical page a pleasingly concrete sense of purpose.

August 18’s newborn domains include an obsolete pen plotter clocking in at 09:30, emergency warnings designed for sight, touch, or hearing, a funeral-folder tool calibrated for printer drift, and photographs of Colombian rental signs turned into a housing map.
