I still don't understand how all of this works. It doesn't make any sense! How is there an interference pattern for the double slit with the electrons? How can it go through both, then one, then none? It's impossible.
Also when there was a device to see which slit it went through, the electrons went back to behaving like marbles. It went back to producing two bands. How is this so? How could this be just because there was something watching which slit it went through? The electron acted differently just because it was being watched? How did it know that something was watching it? There were two different results, one that was being watched and one that wasn't.
From this...
How can we know that anything we have observed in the past, especially about electrons, is right?
Because no one knows really for sure whats up with quantum mechanics, I don't think that chemistry honors students should be learning about this. After "learning" and watching about quantum mechanics, many of my classmates were confused about what we just watched or "learned" about. When someone has solved the many questions of quantum mechanics, and the idea finally makes sense, then we should be taught what its about.
At least for now, probably my classmates and definitely I am very puzzled with the concept of quantum mechanics.

Did you know?
To start off, I don't understand how this has anything to do with chemistry and why this was assigned as homework for this class. I felt as if watching this YouTube video was pointless and just a waste of my time.
As I was watching it, I wondered to myself, "Why do I need to care about all the facts that were on this video?" Even as I'm writing this, I still can't think of an answer. So in all, I didn't really care about these facts. Sure, some of the ideas they talked about like how there are students studying for problems not even here yet was somewhat educational, but most of the facts presented on the video was useless. For example, telling us that if "my space" was a country, it would be the fifth largest, was a complete waste of my time. Personally, I don't care if this is true. That's great for "my space."
Also, I don't think that this video is fairly accurate. They had so many predictions and sure, they may have had some information that lead them to the conclusions, but they are not psychics. These predictions have only a small percentage of being correct. For instance, what if earth gets blown up in a year? The facts they predicted fifteen years from now will not happen because no one will be alive. In addition, as I said before, I did not care about all of the facts that said that this or that was going to happen in some amount of years. For example, "China will soon become the number one English speaking country in the world." I DON'T CARE. What does the person that put this up want the watchers to do? This too is not that accurate. It says, "soon." How close is soon?
Another fact that got me angry was about the IQ's for India. "The 25% of India's population with the greatest IQ's is greater than the total population of the United States." That is great that they are smart. Personally again, I DON'T CARE. Also, why did they only talk about the smart people. Why didn't they talk about the stupid people in India compared to the United States?
Moving on...
Some parts in the video did not make sense at all. "Using technologies that haven't been invented...". Would someone care to explain how this makes sense at all? How can they be using something that hasn't even been invented yet?
In all, everything about the number of people on "my space", amount of google searches, amount of texts, market audience, amount of words there are, what happened while I was watching this video, and basically everything else was insignificant. This video did not help me gain any knowledge whatsoever. I will never have to know any of this useless information in my life unless there is a game show I'm participating in that has all of these random, useless facts.
This is how I honestly felt about it, and I'm sorry if my constructive criticism is too harsh. On the bright side, I liked the music...sort of.
