no, any technological innovation comes from the experiance of the dwarves, who can now handle making more difficult products.
Yep. The way I see it, dwarves are great manufacturers and engineers, but they really don't seem to record any scientific progress, which would kinda be required for advanced physics and things like electricity and steam engines.
Are you saying that it shouldn't be in because it's not in?
Evolving tech levels shouldn't be in cause well, their science doesn't really advance as the things aren't written up(Well, I haven't never seen E=MC^2 in the engravings, neither I've seen any paper being produced). Dwarves are kinda like Romans in that way, good engineering, some innovations, but not much scientific progress. I think it could be blamed on the alcohol also!
Ever heard of the aquaduct, many medical and surgical tools, the cesarean section, fast drying cement, reinforced concrete, the military camp/military construction procedures (such as Ceasar's bridge across the Rhine), the grid system of city planning, the professional army (not sure on this one, but they certainly developed it (particularly Marius)), much of many modern legal systems, satire, &, etc., NB, PS, Curriculum Vitae, Senator, Republic, Plebeian, Prefect, President, Legal, Penal, Judge, Judicial etc., the Julian Calendar, the seven day week, Christmas, Christianity, door locks, pedestrianised areas, the pavement, the census, central heating, the apartment block, the public newspaper, the sock, a variety of trumpets, the umbrella, the public toilet, various cosmetics, candles (edible ones), the mangle, scissors, the magnifying glass, different left and right shoes, the bikini, the shower, the public spa, pool, gym, library etc., the postal system or street lighting? They were all Roman inventions. Do you think that those who developed the wheel or other such developments wrote it down? It is quite possible for science such as metalworking to advance without writing.
