Back to the list of units
A Great Person, specialized in science research.
- Construct an Academy (Great tile improvement)
- Discover Technology (Grants a free technology in vanilla. Produces Science in and .)
The unit is expended after performing either of these actions.
In vanilla Civilization V, the Great Scientist can use "Discover Technology" to grant you a free technology. In Gods & Kings and Brave New World, this ability is replaced by the "Boost Science" ability, which lets you immediately gain a large number of science points based on the science output of your civilization. It is usually enough to finish researching the current technology, and even boost another one! Use this if you need an immediate result.
Note that you can use Boost science from anywhere; you don't need to move the Scientist anywhere specifically.
Alternatively, the Great Scientist can construct an Academy for a long-term Science boost in a city. In the early game, constructing Academies is recommended, as the long-term science gains will surpass the instant gain of Boost Science. In the later game, Boost Science may be worth many tens of turns' worth of Academy science. Since you can see how much science Boost Science is worth by mousing over the button, you can judge its worth based on how many turns you expect are left in the game (or until you get enough tech to go for your desired victory). Since the Academy affects the science output of an individual city, its gains are augmented by all science buildings with a percentage bonus, like the Research Lab.
The number of beakers granted by Boost Science is calculated as follows:
Quick: Total of last 5.36 turns of Science output Standard: Total of last 8 turns of Science output Epic: Total of last 12 turns of Science output Marathon: Total of last 24 turns of Science output
In the XML files this value is actually defined as
(Science income) * <BaseBeakersTurnsToCount> * <ResearchPercent> / 100
where BaseBeakersTurnsToCount is defined under <Units><Type>UNIT_SCIENTIST</Type></Units> and ResearchPercent is defined under <GameSpeeds><Type>GAMESPEED_MARATHON</Type></GameSpeeds>, <GameSpeeds><Type>GAMESPEED_EPIC</Type></GameSpeeds>, <GameSpeeds><Type>GAMESPEED_STANDARD</Type></GameSpeeds> and <GameSpeeds><Type>GAMESPEED_QUICK</Type></GameSpeeds>.
The default value of BaseBeakersTurnsToCount is 8, while the default value of ResearchPercent is 67 for Quick, 100 for Standard, 150 for Epic and 300 for Marathon.
It should be noted that the output of Boost Science varies wildly in the first 8 turns. During this time the game sets BaseBeakersTurnsToCount = 3 on Turn 0, then BaseBeakersTurnsToCount = 4 on Turn 1, then BaseBeakersTurnsToCount = 5 on Turn 2, and so on until the turn number is equal to the value of BaseBeakersTurnsToCount set in the XML files. At this point, it will begin using the correct BaseBeakersTurnsToCount value. This appears to be a testing mechanic that was not removed from the game on release, due to the fact that it is impossible to acquire a Great Scientist prior to turn 8 in an unmodded game. If you are modding the game or creating a scenario, make sure that you do not give players access to a Great Scientist in the first 8 turns of the game.
Also, if you make a mod that significantly increases the ResearchPercent value but not the rest of the gamespeed values, you should decrease the BaseBeakersTurnsToCount value to avoid Boost Science becoming overpowered.
Setting BaseBeakersTurnsToCount = 0 will remove the Boost Science ability entirely from the unit.
"Great Scientists" figure out how the world works. They discover that the earth orbits the sun. They sequence DNA and invent quantum mechanics. They cure polio and predict eclipses. They make a civilization smarter. They invent the future.
