[b:d5f38f5fff]Good morning, I read that one of einstein's three papers published in 1905 is about browno\ian motion , it states that the perpendicular distance moved by a brownian particle is directly propotional as the square root of the time , for example in four seconds it moves 2 cm, in nine seconds it moves 3 cm and so on , so the body is slowing down , it is deccelarating , what is the reason for this deccelaration and what is the effect causing it , is it related to the soultion ?? Thanks :) [/b:d5f38f5fff]
