I'm applying to a Ph.D. program (in the field of robotics) and I have a hard time to fill the personal interests. I initially was going to avoid that section but then I got convinced that it's not a bad idea to have it. But I digress...
One of my hobbies is reading* about science, mostly in mathematics, [astro]physics and science in general. The problem is, I don't know how to write this in a clear, honest and concise fashion. I don't want to simply write "reading" because I don't want to be that generic applicant! Also I want it to be clear that this reading is not related to my professional field. And last but not least, I don't want it to sound fake!
*also watching or listening. Sometimes I also code for fun, generally speaking I fool around the science.
