3:30 You got the column and row formation backwards. Rows go from left to right. Columns go up and down. So if the rows are supposed to represent the vertices, it should be 5 across. It would be 9 up and down representing the edges.

At the beginning of this video, she explains that the mean is the balance point. This is inaccurate. The balance point is the point that half are greater than, and half are less than - this is the median, not the mean. Draw a graph for the sugar shop sales for a week. They sell no sugar on Sundays because they are closed. They sell 10lbs on Monday, 15lbs on Tuesday, 25lbs each on both Wednesday and Thursday, 40lbs on Friday, and 30lbs on Saturday. This creates a curve that is skewed to the left. Now, picture the weight of all the sugar on a balance. There is 145lbs of sugar. Start adding the sugar up by days and draw a line 3/4 between Wednesday and Thursday. This is the median - the balance point. Where half of the sugar is on one side, and half is on the other side. If you actually drew this graph, the mode is on Friday, and the mean is half way between Tuesday and Wednesday. Hope this helps someone!

The median is not the balance point! Think of a really small data set: 1, 4, 4. The average is 3 and the median is 4. However, if you put these on a number line, you don't expect the balance to be at 4. The 1 would weigh this down. Instead, you would need to put it at 3 so that it balances the 1 on the left, and the 8 (2 fours) on the right.

Since all sets have the ∅ element, does that mean all set operations include ∅?

to answer the question at the end of the video: generator "a" is not necessarily unique, because any value of "a" which is prime with respect to the mod # (in this case prime with respect to 6) could be the generator, in this case, that would be 1 & 5 which are both the generator here.

There is 1 matrix of constants and 2 the functions of time . LI depends on which one of them ? Also how are the functions if time picked ? In a homogeous case are the solutions uniqe ? how is valye of one of the variables picked ?

around 1:00, adding a 7th line contradicts A1, and there was no contradiction to A2 originally (unless I'm missing something). However, Fano's Geometry does not not satisfy the original axioms given at the start, so the original axioms are not equivalent to the fano axioms, I would recommend sticking to the traditional ones, although they are a bit messier.
