Many times in class, teacher questions students: "What else do you think should be included in the experiment?" Many times, the correct answer is: "Controls, positive ones and negative ones." Yes, we need controls in experiment. I have positive controls and negative controls….but they are just controls, never take over the place of experimental ones. How if I never get a good experimental one? Then nothing works out in the end.
Sometimes I think I know what or why. Sometimes I doubt. But, all the time I believe I don’t really need to know….
That’s life, at least my life, which I have to face and have little power (or even little desire) to change, no matter I like or not. So, take care, to all of us.
While writing this, music from the lab sounds so soft, sad and beautiful, just like a sigh, echoing in the deep lonely night.
