I asked this in ASB because of why I'm thinking it, but the technology stuff might be better here. If people just want to post links even that would help, becasue I know there have been various threads on "early radio," "early photograph," and so on, just very spread out.
Obviously a starting point would be needed, but if a country like France, with an absolute monarch, devoted lots of money to get scientists to come and research and experiment to deveop techniology, *and8 (the ASB part) some basic info on how some thigns were done was present, how fast would it be till some of the following were developed:
Telegraphs; telephones; radio; photography; film/movies; color of the last two; electricity; artificial light; heavier and lighter than air flight; and any other things you want to mention.
You could also just sum it all up by saying "Robert Boyle's list of thigns he'd like to see ivnented someday."
Thanks.
