1. East meets West: Collaboration goes National WARM CONGRATULATIONS to IRMACS Welcome to D-DRIVE whose mandate is to study and develop resources specific to distributed research in the sciences with first client groups being the following communities High Performance Computing Mathematical and Computational Science Research Math and Science Educational Research 08.04.05

2. We look forward to a partnership role with IRMACS in  Research  Research training  Outreach educational industrial Pan Canadian Collaboration The May AMS cover features math in the NewMIC cave

3. Experimental Mathematics of Hyperbolic Knots (@) We have certain knowledge but no proof of this---the simplest of 998 hyperbolic volumes

4. Experimental Mathematics and Zeta Functions Bailey, Bradley and I have recently discovered and proved in Maple three equivalent identities this hypergeometric identity is easily computer provable after using PSLQ up to 50,000 digits (250 terms)

5. ACEnet completes the Pan Canadian Consortia ACENET and HPC@DAL Dalhousie’s role will be in collaboration, visualization, and large data-set storage
