The Pithy Quote
Date: Sun, 10 Jul 2005 15:44:41 -0400 PS: Alas, in these modern times, these young folks just don't know their descriptive chemistry like us old guys do. I predict disaster and catastrophe - as we old guys die off, the world will be left with chemists who don't know descriptive chemistry. Alas and Alak! (or whatever)
- Jay Young My version of this statement is that 21st Century Chemistry Education focuses on discovery processes, using specific chemical techniques and information management. This does not necessarily translate into transferable bench-top skills; of particular concern is safety skills.

TheCon(nuingEvolu(onofScience
Lab science in the 21st Century is an emerging complex system which highly values converging knowledge.
Changing Science Learning Styles

LookingforStructureintheElectronicData
• How large is the PubChem chem safety information universe?
• How high quality is it (including consistency & provenance information)?
• How large is the Wikipedia chem safety information universe?
• How high quality is it?
How much overlap is there between the two?
Key safety information fields: - GHS class designation(s) and
signal word - NFPA diamond information
10,000 Chemboxes
Millions of chemicals; 3500 with GHS info
