Geni's points were that A-bombs are not H-bombs (which I did not address, and is correct), that A-bomb explosive lenses are somewhat problematical (which I disagree with), and that H-bomb design contains significant elements of speculation (which I disagree with generally - specifically to large and mid-sized H-bombs, which are not that complicated - but I do not disagree so much about very compact H-bomb design, as the specific geometry of the use of Foglight in the last generation of designs is still somewhat opaque in public knowledge). I don't need to reread the article; I've written large parts of it, and could write a book sized version with all the ugly math and specific examples. -- -george william herbert george.herb...@gmail.com _______________________________________________ WikiEN-l mailing list WikiEN-l@lists.wikimedia.org To unsubscribe from this mailing list, visit: https://lists.wikimedia.org/mailman/listinfo/wikien-l
