even in 1985 richard henderson had written a paper showing that audit be possible for atomic structures from electrons. a few people at the time actually believed although they cannot find any fault with its paper. people had to figure out how to get signal in the line and particles and get structures from them. he was one of the leaders. until about 2012 or so the technology had not reached a stage where you could get structures. and now you can. but i have to tell you it's not all panacea. the problem is, the particles are not constrained in any way. that is both good and bad. you see the range of dynamic constellation so they can have. it means and you can't get a high resolution picture of the three or four parts of the martyr under molecule. often many molecules will fall apart when you make the grade. were reaching another black box area which is the preparation and the goo.people don't reallyd solution for that. >> one of the things telling a story always brings up is ending. and in one sense it feels like there were two indians to a story and one the moment when you publish on t
