This post is about the students who people; in general, think they have suicidal tendencies, due to their unexplained choice of the path of life. Yes, I’m talking about those who study any natural science. Those who have chosen, with their free will, to continue the ‘ecstasy’ provided by ‘the most desired’ subjects known to man, a.k.a. math, physics, chemistry, chemistry, computer science.
Even though you are up to your neck with materials that you need to sponge it up your brain, I was thoughtful and found hundreds more that you can dip in them with great joy.
Sorry for the poor jokes. Actually it is about other science related materials, but not for causing confusion, on the contrary, for more thorough understating of certain scientific topics.
