How every result is checked

Editorial Standards

Every derivation on physics2u passes the same four checks before it is published — the same discipline the site asks you to apply when reading any result: state the assumption, check the units, verify the number, and trust nothing you can't re-derive.

01
Dimensional consistency
every result equation reduces to consistent SI dimensions
verified
02
Numeric verification
worked value reproduced from first principles, agrees to four significant figures
verified
03
Independent authorship
each derivation written from the physics, not transcribed; sources cited for cross-check only
verified
04
Full cross-link integrity
each lecture citation points to a live derivation; each derivation is reachable from at least one unit
verified

This is the same standard laid out in full on the Method — the eight rules every page is built to obey.

See the method, the derivation vault, or a worked example at D-001.
