Nevermind that, he told me he is doing the following:
Raising money with Zero % science and putting entertainers to scientists, so he researches for a while just one step a turn. Then putting science up to 90 or 100% and researches until the accumulated money is empty. He will gain from this the "free" research from scientists. It this true?
If I understand you correctly, then I don't think this is true. You have to either invest 40 turns of nominal research (50 in C3C) in your tech or provide the full amount of necessary beakers.
You will get a reduced price for techs, once someone you know has learned that tech. I never bothered to figure it out exactly as CAII will tell you. It amounts to about 10% for the second nation and it goes down for each additional nation.
2880 to 2057 seems too large for second nation. Here is the formula:
***The formula presented below is accurate for PTW. It is probably also good for C3C, once the additional difficulty levels (e.g. Sid) have been added.

This is the formula for research cost for v1.29f.
Research Cost = [MM * [10*COST * (1 - N/[CL*1.75])]/(CF * 10)] - Research done so far
Research Cost and research done so far are in gold.
Square brackets indicate truncation /rounddown
MM = map modifier(tech rate on world sizes tab in the editor)
Tiny 160
Small 200
Standard 240
Large 320
Huge 400
CF = AI cost factor(as on the difficulty tab in the editor)
For the purposes of the research cost formula, CF has a maximum value of 10.
Chieftain 20
Warlord 12
Regent 10
Monarch 9
Emperor 8
Demi God 7
Deity 6
Sid 4
COST = technology cost as on the civilization advances tab in the editor.
N = number of civs on the diplomacy screen that have discovered the tech.
CL = number of civs left in the game
There is only one part of the formula that varies during the game: (1 - N/[CL*1.75]). There are two ways in which you can increase it to lower tech cost:
1. Increase N by exploring and buying comms to add civs to your diplomacy screen.
2. Decrease CL by killing civs.
NB. This formula is relevant for research cost of the AI civs, not just the human player. If you are interested in the research cost of a specific technology for a specific AI civ, N refers to the number of civs on that specific AI civ's diplomacy screen that have discovered that specific tech. In general, there are two ways in which you can increase AI tech cost:
3. Keep N low by not selling comms to AI civs.
4. Keep CL high by not killing civs.
And technically...
5. Keep N low by not getting techs yourself.
Obviously points 2. and 4. are contradictory so choose whichever fits your playing style. Personally I choose point

Steam is 2880 on a std map at regent. This means if you knew 3 nations that knew it, you would pay 2057.
