When you consume a Great Scientist on research how many beakers does it produce? Is there a cap to how many technology you can unlock by bulbing Great Scientists?

I'm pretty sure it's based on the science output of your civ, like it gives you "x" amount of turns worth of science. I could be wrong though, and I don't know the exact amount. – Mr Smooth Jul 13 '12 at 6:40

A great scientist when expended gives you the total of your last 8 turns of science output.

This includes science from city-states, bonuses, etc.

Do any beakers every get wasted? or does it rollover into other technologies? – grom Jul 24 '12 at 0:58
It rolls over to the next technology you're researching – Graham Wager Jul 24 '12 at 15:42
Does it include the big bonus from expired research agreements? If so, it would really pay off to start a bunch together and bulb at the end. – David Harkness Aug 1 '12 at 14:51
If the science boost is based on the total output of the empire, then would it make sense to re-assign all the specialists and workers in all the cities to get some extra science and then use the Great Scientist and then change everything back? – Mats Volberg Sep 12 '13 at 15:15
Science specialists are usually assigned in major cities anyway so it doesn't have much of an impact anyway. Not to say it is never useful but its a lot of work to go through for a relatively tiny improvement (minor improvement in science at the cost of whatever else – Lawton Sep 12 '13 at 15:27
