I didn't understand why they had to move the bottom row of numbers infront of the top row of numbers. Like when he shifted the numbers when he applied the S2]]> 2016-09-26 20:12:41 UTC https://padlet.com/bruceito/n4qblq4p17tw/wish/126507931 https://padlet.com/bruceito/n4qblq4p17tw/wish/126508153 I do not agree with this statement (1+2+3+4+5+...=-1/12) because in the video, many liberties were taken that jeopardize the truth of the  whole equation. For example, in the first sum (S1), the video says that 1-1+1-1+1-1+1-1…=½. They figure this out by averaging 1 and 0. I do not think that this fair because the sum is never equal to 0.5-- just because it is infinite does not mean that you can average it; therefore, I think this equation must be classified as undefined and the main sum is naturally different. Also, when calculating the second sum (S2), the people in the video conveniently moved the bottom number over a digit into a “nice” place. By doing this they clearly change the outcome and do not compensate for this movement later on. Obviously, these two examples are bits of “mathematical hocus-pocus” that clearly change the outcome of the sum. The only effective point that I think is made in the video is the point that in physics, there are no infinite answers, and that -1/12 comes up quite a lot in different theorems. However, how could a positive plus a positive plus a positive and etc. equal a negative number?

I thought that it was amazing that equations that involve sequences of number that go on until infinity could be solved with an answer being a rational number. I think I will need a lot more practice at solving equations before I could do anything like that. The man in the video talked about how these equations can apply to physics problems. I am looking forward to learning about how this helps solve real life physics problems. ]]> 2016-09-26 20:13:52 UTC https://padlet.com/bruceito/n4qblq4p17tw/wish/126508169 https://padlet.com/bruceito/n4qblq4p17tw/wish/126508176 When I looked at it without breaking it down, I thought, 
how could all those positive numbers (1+2+3+4…..) Make -1/12? But when he broke it down it made more sense.]]> 2016-09-26 20:13:54 UTC https://padlet.com/bruceito/n4qblq4p17tw/wish/126508176 https://padlet.com/bruceito/n4qblq4p17tw/wish/126508189  I felt that the theory might of been possible, but the answer seemed to be placed together a bit randomly. In the video, the man explains (for example) to move it to the side a bit. That seems a bit peculiar, which leads me to believe that they were purposefully trying to get to the answer of 1/12. I feel that doing the math in a certain way could affect the answer. The infinite topic is already quite complicated, but while watching the video, I thought to myself, “Why would they need to shift it?” It seems to me that they were trying very hard to get an answer that would “blow” the reader/audience’s mind.

If one day I give you $1, and the next day I give you $2 and so on, unless you spend the money, I don’t understand how you could end up with $-1/12.]]> 2016-09-26 20:14:01 UTC https://padlet.com/bruceito/n4qblq4p17tw/wish/126508198 https://padlet.com/bruceito/n4qblq4p17tw/wish/126508211
I didn't really understand why they had to shift and everything.]]> 2016-09-26 20:14:07 UTC https://padlet.com/bruceito/n4qblq4p17tw/wish/126508211 https://padlet.com/bruceito/n4qblq4p17tw/wish/126508243 I found the equations very confusing when they were moving the numbers to the next row. For example I did not under stand why the shifted all the digits when S2 was added.

I didn't really understand how he got -1/12. Why did he have to shift the digits when he added S1+S2 and so on? Why couldn't he have left the digits the same? ]]> 2016-09-26 20:14:29 UTC https://padlet.com/bruceito/n4qblq4p17tw/wish/126508314 https://padlet.com/bruceito/n4qblq4p17tw/wish/126508341 I found this interesting. I didn't know that you needed S, S1, and S2 formulas to solve this equation. I also noticed at the end of the video the man used algebra that we could do to solve the equation. In addition, the comment made by the filmer was "what if I stopped the formulas at google?". The interesting thing was that doing that would cause you to have a bigger number. But going on forever would give you a negative number. Again, I'm not sure how the man came up with S, S1, and S2 or why he decided to add or subtract them.]]> 2016-09-26 20:14:35 UTC https://padlet.com/bruceito/n4qblq4p17tw/wish/126508341 https://padlet.com/bruceito/n4qblq4p17tw/wish/126508346 At first when he said 1+2+3+4+.... Was equal to 1/12 I was confused but when he broke it down I kinda of got it. But I still feel confused.

After watching the video more than once it’s still hard to believe all positive numbers together equal -1/12.]]> 2016-09-26 20:14:38 UTC https://padlet.com/bruceito/n4qblq4p17tw/wish/126508355 https://padlet.com/bruceito/n4qblq4p17tw/wish/126508399 I, personally, an still a little confused as to how they came up with moving the patterns over and what not. I sort of get how they got the equations (like from the physics book). The guy who figured out the answer to the equation said that these types of these equations a lot in physics. I don't really get why we need to know the answer to this equation but good job to them for figuring out the answer.

Why do you use the 4 out of the other numbers?]]> 2016-09-26 20:15:15 UTC https://padlet.com/bruceito/n4qblq4p17tw/wish/126508481 https://padlet.com/bruceito/n4qblq4p17tw/wish/126508506 I personally found the S1 and S2 formulas weird because they gave no explanation and didn't know where it came from. Also it doesn't seem right because if you don't have the S1 and S2 formula, how do all the possible natural numbers equal a negative fraction. Personally it didn't seem logical.]]> 2016-09-26 20:15:20 UTC https://padlet.com/bruceito/n4qblq4p17tw/wish/126508506 https://padlet.com/bruceito/n4qblq4p17tw/wish/126508563 I didn't understand how they came up with all the different equations and sums. And 
I didn't understand what the first sum had to do with the end result? Along with that like many other people I'd like to know why they shifted the digits when they added S2 ]]> 2016-09-26 20:15:43 UTC https://padlet.com/bruceito/n4qblq4p17tw/wish/126508563 https://padlet.com/bruceito/n4qblq4p17tw/wish/126508727 I don't think it's possible for 1+2+3+4... will result in -1/12 because at the first S1, they used an average of 1 and 0 because they didn't know whether or not infinity stops at an odd or even place. Because the average was a fraction, 1/2, the final answer became -1/12 because fractions divided by whole numbers will become smaller fractions. The average is not completely accurate. If the actual answer of S1 was 0 or 1, the answer would be completely different. Furthermore, both S2 and S kept going back to S1, which is not correct for sure (since it is either 1 or 0 and not 1/2), the wrong answer affected all of the equations. But despite starting off wrong, this equation often appears in physics, where they did not get infinite numbers as the answer of 1+2+3...]]> 2016-09-26 20:16:36 UTC https://padlet.com/bruceito/n4qblq4p17tw/wish/126508727 https://padlet.com/bruceito/n4qblq4p17tw/wish/126508826 Youtube Comment #1 

Cool, this makes sense.

Youtube Comment #2

Why is it that you added a minus in front of the bracket at 5.01?]]> 2016-09-26 20:17:05 UTC https://padlet.com/bruceito/n4qblq4p17tw/wish/126508826 https://padlet.com/bruceito/n4qblq4p17tw/wish/126509065 While watching this video, it’s mind-blowing to see how these answers are formed. Honestly, if I had to find a theory for this question, I would have quit. The theory S2 equals -1/12 is about thinking out of the box which isn’t necessarily one of my strengths. After watching this video, it makes me want to do more things like this to help me get out of the box. ]]> 2016-09-26 20:17:39 UTC https://padlet.com/bruceito/n4qblq4p17tw/wish/126509065 https://padlet.com/bruceito/n4qblq4p17tw/wish/126509299 Why did he have to shift all the digits when he added S + S?]]> 2016-09-26 20:18:54 UTC https://padlet.com/bruceito/n4qblq4p17tw/wish/126509299 https://padlet.com/bruceito/n4qblq4p17tw/wish/126509323 I don't really understand, how the numbers can add up -1/12, since if I bought 1 apple, then 2, then 3 and so on.
