Schrödinger's Cat.

 There is a living cat in a steel chamber, along with a device containing a flask of hydrocyanic acid. Inside the chamber, there is also very small amount of a radioactive substance that decays over time. The odd of occurring radioactive decay is 50%. If the decay occurs, a relay mechanism will hammer and break the flask, which will kill the cat. The observer cannot know whether the cat was killed or alive until checking the inside of the chamber. Until then, the cat is, theoretically, both dead and alive. This is a 'thought experiment' that was designed by an Austrian physicist, Erwin Schrödinger. He noted that the observation or measurement itself affects the outcome. In other word, the cat will be inside of the chamber, either dead or alive, but it depends on the observer to determine the status.
 Recently, I heard some concerned comments from my parents, which reminded me of the Schrödinger's cat. I am currently in grade 12 and aware of the importance of this year more than anyone. Much effort  has been put on the school works, but my parents are concerned about my academic excellency and the amount of time put for going out with friends or going out for photography. Alas. I do appreciate their concerns, but it's also bit disappointing to realize the distrust. According to the Schrödinger's thought experiment, there are various ways to observe and interpret the status of the cat. Although only the cat knows well enough it's own status of being.
