Real life has claimed yet another fine mentor here at PF. This time it is the 6 year veteran vanesch. vanesch has helped anchor the Physics forums over that span. No doubt we will miss his expertise and humble nature! Thanks you vanesch! Hope you pop in and say hi often!!! Furthermore, in a response to our busy expectations for the homework help sections this coming school season we are delighted to announce the promotion of Mark44. Surely this is little surprise, as Mark44 has been a leader in homework help forums for the past few years! Congrats!!!
