My reflections on uncertainty:

I like the example of uncertainty pertaining to light. I think this example makes sense. Light can be seen as a particle or wave depending on how it is being measured but not both at the same time. This can be hard for people to comprehend. Not till then end of class and looking over the articles again did I start to understand the uncertainty principle. To me the principle is saying the light can be a wave or a particle it just depends on what we are measuring at the time. I am interested if it can be both at the same time but I think that would be impossible to measure. If it was possible I bet it would have already been measured. I like Schrodinger's Cat example. This example makes the physical versus the subatomic clearer to me. We cannot have this same uncertainty at the physical level as we can at the subatomic level. I liked the uncertainty discussion. It really got me thinking hard and wanting to understand. It is a different way of thinking than I am used to. Uncertainty does not make sense but at the same time it does. 

My comments on causality:

The thought of us causing a result by observing and measuring is an odd thought. I had always thought before that the same result would happen if we were observing or not observing. But I had only thought of this at the physical level not the subatomic level. From what I have read it seems like with particles and momentum or light being a particle or wave we can only measure one thing at a time. So in measuring that specific thing we get that specific result. With the light measurement examples given it seems to me that we are causing by measuring. Therefore I like the theory of causality at the subatomic level with particles and momentum.

Is the Universe weird?:

I would not say that the Universe is weird, I would say that it is mysterious. It is amazing to me how detailed we have become with science and physics. The Universe is such a complex place and there is so much to discover. I do not think we will ever unravel everything. There will always be different theories and new discoveries. What I always do wonder about is how this Universe came to be and all its creatures, nature, elements, etc. I am also very curious about afterlife and what happens when we leave the universe. This to me is where the mystery lies. This is a mystery that will never be fully explained.
