quantum mechanics

Quantum mechanics in general just baffles me especially the double slit experiment. It is beyond bazar how when something was observing the electrons they acted differently I just don't understand how that is possible and how it happens. Some questions that pop into mind when i think about it is how does electron know that it is being watched. I know thus far we can't answer this question I just think it could be the most bazar thing I have ever heard of. And the fact that the electron acts differently when it's being watched leads us to think well then is anything we see really correct, could it also change while it is being observed? Which then leads to many other questions in my mind. I think the subject though is very intriguing yet confusing at the same time. I wonder when the questions of QM will be solved

Video

Well first off I really enjoyed watched the video, it really made me think and realize things that have never even popped into my mind. For example it is so hard to grasp the concept that there are jobs we are training for that have not yet been created, I cant even wrap my head around that is possible. Then I began to think about what other jobs at this point are still waiting to be created? What else do we citizens really need? I honestly can't think of any other jobs we need in our world yet more jobs are to be created. 

Also the clip put into prospective how attached and involved people are with modern day technology. It stated that one in eight marriages have now started from online in comparison to less modern times when all marriages where either face to face meeting or arranged marriage. The next aspect of technology that really surprised me was the text messaging statistic, i would have never guessed that that many texts are sent a day.

overall that was a really great clip it had so much information in a short amount of time.
