Because yes

 Hello! Me again!  There's one person that I admire and it's Dr. Raphael Mechoulam. He is a chemistry scientist that, one day, started to study cannabis plant because nobody had done before, and having a small laboratory, was not feasible to provide competition to big laboratories with other more studied topics, and unintentionally discovered and isolated the THC and, several years later, the endocannabinoid system.  This discovered was very important to science, specially for medical botany and, even nowadays, inspires many studies with latest technology that can help people. Dr. Mechoulam was born in Bulgaria in 1930, but in the times of Nazi Germany and after the capture of his father, they had to migrate to Israel, where he enlisted in the army and finished his chemistry major. In the 1950s, after his post-doctorate, he entered the Weizmann Institute of Science, where he discovered THC in his laboratory. I admire dr Mechoulam because he did all of that in a small lab ...

 Hello, there! It's me, again :) Today I'd like to talk about my major and its relationship with the world.  Chemistry is wonderful and had provided many things to humanity troughout the centuries. Thanks to it and other sciences we have everything we know today. So, do you thing chemistry will bring us better thing on the future? I think that's absolutely yes. It is very important to us nowadays. Thanks to it togheter with other majors we have, for example, covid vaccine today and, of course, more thing will come in the future.  As a future chemistry scientist, I would like to contribute with new discoveries. Maybe not a big one like a new element, but something that can help the people or animals. Even if only to provide evidence of something that is already known.  What is absolutely certain is that chemistry will never stagnant. There will always be new things to discover and, of course, people who will benefit from it.
