comment Variance of a special random walk
@Did: You asked for the bigger context of this problem and I posted another question here: math.stackexchange.com/questions/1309230/… - This time I really tried hard to give all the necessary information, let's see if this is sufficient for your critical eye ;-)

comment Connections between the solution of simple ordinary equation, normal distribution and heat equation
Do you see a connection between the heat equation and the above ode? Both have the normal distribution as a solution, is this a coincidence?

comment Connections between the solution of simple ordinary equation, normal distribution and heat equation
Thank you. Ok, I understand that but doesn't it show that the normal distribution is the simplest and in a way most natural unimodal distribution?
