Description

Jean-Claude Bradley presents at the American Chemical Society on August 16, 2009. The talk starts with highlighting how Open Notebook Science has been used to shed light on the recent report of using sodium hydride (NaH) as an oxidant. Next the Open Notebook Science Challenge is described, where ONS coupled to crowdsourcing is used to measure and share non-aqueous solubility data. Recent developments in using bots to contribute to the scientific process and applications to the Ugi reaction are mentioned.

The NaH oxidation controversy

Information spreads quickly through the blogosphere

15% NMR yield

Motivation: Faster Science, Better Science

Open Notebook Science Logos (Andy Lang, Shirley Wu) Sharing: how much and when

There are NO FACTS, only measurements embedded within assumptions Open Notebook Science maintains the integrity of data provenance by making assumptions explicit

TRUST PROOF
