DVD Spectacular
$24.98
This is a DVD made for professionals that understand what they are doing. It comes with a 10 page booklet, and I mean a tiny tiny tiny booklet that gives very minimal details except for perhaps what tracks are on the disk. This booklet is so bad that even sound engineers would be bummed out since it does not even provide the most minimal tech info as to vu levels to set, responses etc etc I mean even using a sound level meter I had no clue as to what I was looking for. Another thing that bothered me, once I started any tracks or test I had to push EVERY button on my remote to get the thing to stop ....The dvd also contains video tests and if little is said about the audio portion even less is said about the video. pretty colours and dots & squares though... The ONLY thing this dvd does, and why at least it has 1 star, is allows you to check frequency responce from sub woofer to the highest tweeter and all the speaker channels for a 9 speaker setup .... Dont waste you money unless you KNOW what you are doing

Knowledge Contributors (Synthese Library)
$32.00
In the late 1950's and early 1960's seminal works on the logic of knowledge and belief were published by notably von Wright and Hintikka. Epistemic and doxastic logics have since then grown into mature disciplines enjoying many important applications in philosophy, computer science, game theory, economics and linguistics to mention but a few fields. The aim of this thematically unified anthology is to track the history of epistemic logic, to consider some important applications of these logics of knowledge and belief in a variety of fields, and finally to discuss future directions of research with particular emphasis on 'active agenthood' and multi-modal systems. Knowledge Contributors include H. van Ditmarsch, R. Fagin, J. Halpern, J. Hintikka, W. van der Hoek, B. Kooi, W. Lenzen, Y. Moses, H. Rott, J. Sowa, M. Vardi and R. Wojcicki. Knowledge Contributors is accessible to researchers as well as graduate students in philosophy, computer science, game theory, economics and related disciplines utilizing the means and methods of epistemic logic.
