This blog is here first and foremost to parametrize the authors ignorance. Any comments which make this ignorance sharper defined welcome.
The subject of posts will (should) be issues related to amplitude calculations in string and field theory. This has been a very fruitful adventure over the last years initiated by Witten's twistor string proposal. Since the author is working in this particular field as well, don't expect not to read any gratuitous self-promotion :)
