comment Explanation for the next steps of chaplygin dipole
Thank you very much for your explanation!! I believed I will understand it if someone would explain me in other words, but I didn't believe how much I would understand! thank you!!

comment Explanation for the next steps of chaplygin dipole
@ChristophB. I can understand the steps if the explanation will be more clear.. can you tell me please what is the passing from (2.5) to (2.6) and from (2.6) to (2.7)? which actions of algebra did he use to reach the solution? (I guess that so he got b=3.8317). thank you a lot! if you want, you can write me the answer in "answer the question" and I will accept it. anyway, you can to the same thing in my other question: physics.stackexchange.com/questions/61460/… thank you!!

comment What does Euler equation mean?
thank you both.. sorry for my english.. I give an example: Pythagorean theorem (a^2+b^2=c^2) means that in a right triangle, a^2+b^2=c^2 where: c represents the length of the hypotenuse, and a and b represent the lengths of the other two sides. thank you both!
