Slashdot used to be a cool place where to discuss this kind of stuff, not it's almost impossible to have a scientific dialogue about those things (I know I know since it's not reproducible it's not scientific but you've got the idea). The discussion is polarized in : 1) those are aliens 2) mylar balloons or UAV. This to me raise a few questions that are - really the military with billions of dollars cannot identify a balloon or UAV? - if it's enemy intelligence, secret (also to military) activities of some kind of "agency", why releasing to the public this kind of stuff? - in a zone closed to military training we have no radar, satellites, any kind of other data to mix with the cam footage? Did anyone checked this stuff before releasing it? I don't believe either in manipulation of the masses, other conspiracy theories, but really don't understand why this stuff comes out

I work in the corrosion field and its plausible that the corrosion rate would lower using a surface treatment. But what does stronger for you mean ??? Pls have a look at http://en.wikipedia.org/wiki/M... stronger is too generic..

100% agree

I own a kindle and a collection of 4000 real books. Generally after reading an interesting book with my kindle, if I really like it, I just add to wish list in amazon.com and then buy it when the price is low. I use "real" books as a bookmark for knowledge and as a safe copy of the book. Also having a real collection of book, help you visually to remember what have you read and have an invaluable "social" value, when you want to borrow books to your friend.. and hey they can also be used for interior design. About music I dont' know.. while I still have my vinils, I just put all my cds in a box after converting them to mp3 in my itunes library
