I've been interested in astronomy since I was first taught about it, being about the nine planets in our solar system, in the course of social science in my elementary school, when Pluto was still considered as a planet. Since then I started to read astronomical books, news and sometimes go to observatory. I've also been interested in physcis since I was first taught about it in high school. I majored in physics in univsersity, wherein I found topics regarding gravitation in classical mechanics, like tide, celestial objects' motion loci, cosmology, appeal to me the most. During my graduate studies, I joined the research group of general relativity and was thence introduced to a radically new, intriguing, approach to gravity—envisaging gravity as spacetime geometry—which brings me a new perspective on gravity and has since fascinated me.
