Which came first, the chicken or the egg?
I think that the question implicitly refers to mature, egg-laying chicken. In this case, DNA of a chicken is not a chicken. So the chicken egg came first.

What would happen to space if passage of time was accelerating? Equality principle. Similarity of empty space. A Shrinking matter theory that might actually work.
I understand that galaxies are not expanding. I'm curious, what does space expands within a galaxy mean?

Theory of Computation
Yes, its role is trivial. It doesn't play a non-trivial role.

Theory of Computation
I'm saying that the concept of information doesn't play a role in the theory taught in this course. BTW, it is not an online course. It is a recording from the MIT class, just like all other MIT OCW courses.

It is not about information.

Theory of Computation
You are not mistaken. It didn't touch Shannon entropy yet, and I don't expect it to do so.

MIT OCW has recently uploaded a new complete set of video lectures from this class: Theory of Computation | Mathematics | MIT OpenCourseWare I am 25% through and enjoying it.

Is social media distorting reality ?
Et tu, Brute? The very last time we watched TV was the first Obama inauguration.

Is social media distorting reality ?
In this case, what is a proper label for that kind of social media, the one with the algorithms?

I don't understand gyroscopes
The vertical force he exert is equal to the weight. However, the weight itself, i.e. the heavy wheel doesn't stay above his head. If we look only at the vertical displacement of the wheel, it goes up and then down.

I don't understand gyroscopes
I'm quite positive that the OP is talking about this video: No, it doesn't suggest that the weight changes. It is a pretty good demonstration and is followed by explanation.

Why are two answers different using the two equivalent formulas in combinatorics ?
There is a summation in the formula (2) for A(), but in your calculation there is no summation. So, you have calculated only one components of A(3,2), rather than the value A(3,2). In fact, A(3,2) = 6. For example, if your objects are a, b, and c, then there are these 6 ways to distribute them in 2 distinguishable cells with no empty cells: a | bc b | ac c | ab bc | a ac | b ab | c

No.

A(4-k, 2) depends on k. So, it is not 7. It is different for different values of k.

Why are two answers different using the two equivalent formulas in combinatorics ?
The general form is OK, but the variables are not. First, do it the way in which the eq (1) is given. I.e. use A(..., n) as given and derive A(r, n+1). It Should look like A(r, n+1) = .... A(r-k, n). Second, provide explanation for each component, i.e. what is the coefficient in front of A(r-k, n) and what values of k are you summing for.

You need to do it algebraically, not numerically. Did you see my suggestion about how to do it? Did you try it?

1. You need to derive the equations for generic variables r and n. Working with specific values, such as r=4 and n=2, will not give you a general derivation. 2. The upper limit of summation is still wrong. 3. I don't know where the second part of these two simple sums came from. From nowhere? 4. You still did not derive equation (1). I've given you a fat hint for that. If you derive it, you will see where your summation limit is wrong.
