Contribution grade

Precision measurement · Fundamental constants

Reference score150,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

The discrete-charge pattern and numerical elementary charge were measured more precisely.

Scientific scope

The 1913 sole-authored paper; not sole credit for the whole oil-drop programme or an exact modern value.

Evidence

The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The target is the exact 1913 sole-authored paper. It does not settle every priority or credit question surrounding the broader oil-drop programme and preceding experimental work.
