I have learnt the knowledge of science and engineering for a long time, sometimes I feel confused about the structure of the whole science system. There is lots of hypothesis in the system and most of the formulas of engineering are based on the experiment, the result of which will be affected by the times of trial.  In other words, we just get the input and the output of our world, but we cannot positively say that the logic between them is the true and sole answer. 

Additionally, I love reading Cthulhu Mythos in my leisure time. The story of Mi-Go attracts me a lot. It will collect human’s brains and put them into the big jar, then install some sensor and facilities. I think our life is as ignorant as the jar but we can improve the technology as well as our imagination.
