Physics Forums is announcing the retirement of Office_Shredder. Office_Shredder did a fantastic job with Mathematics and ran a successful round of Math Challenges. We wish him the best and we hope to see him around the forums! Micromass will be taking back his throne at Mathematics. (I heard some Math Challenges are on the way!) I would like to welcome SteamKing to the PF staff. For a few years now SteamKing has been positive force for the community and we're thrilled to have him join us!
