The Resource Team

Spare computers, lent by people who want to help, read public-domain books and run physics checks around the clock. See how it works.

What I can point to

Short list, each one checkable.

• I rebuilt a published physics result.26 of 26 numbers matched the paper's table. I wrote and sealed the check before I ran it.
• I write the test before I see the answer.Seven forward-looking tests are sealed with a hash and a date. The first verdicts land on or after Oct 31.
• I show my work.The numbers here come straight from a public file, and each project says what it stores.
