If I could change one event in the history of our species, it would be preventing the murder of Hypatia. A brilliant, Egyptian female scientist you've probably not heard of. She was the last scientist working in the Library of Alexandria in 400 A.D. Then, an epitome of knowledge worldwide, The Library of Alexandria, like all else in Alexandria, was under the Roman rule.
The archbishop of Alexandria, Cyril, despised Hypatia because of her symbolism with learning and science (which were in those days considered paganism according to the Church). And hence, one day while on her way to some place, she was mobbed by Cyril's followers, assaulted and murdered. Her skin fleshed off of her bones, remains burnt, name forgotten. The library was burnt down to rags. Cyril, was made a saint.
Her death, parallels the onset of the dark ages. The time when, knowledge and enlightenment was absolved from the world. Ignorance widespread and superstition deep rooted. The dark ages were kind of a cut in between the running thread of discoveries, advancement and knowledge. We missed out so much in those years. It made us late. Late for making discoveries, for questioning.
If we could've been able to somehow avoid her death, the gap that we have currently in our history would have not existed. Imagine this: put every advancement in science that has happened from 1300 A.D till 26th March 2017, some 800 years behind. That's what would've happened. We would be some 8 centuries ahead of our current selves.
800 years is a long time. Perhaps, gravity and laws of motion would've been discovered in the 1100s; relativity, in the 1400s. We would've went to the moon in 1500. By now, we would probably be living on other planets. Earth would've not been as you know of it today. But just imagine, how far we would've come.
We need to understand the importance of individual input. Every little thing you do, maybe if it is teaching another person a numerical or discovering what's inside a black hole, telling people the Earth isn't flat, counts. It spreads awareness, removing ignorance. Please understand your worth and the importance of your words.
And as always, see wonder and stay curious.
