Erik Elfwing is 23 years old and lives in Tyresö outside Stockholm. He is studying for a bachelor's degree in physics, year 3, specialising in physics. ‘Considering that I didn't study science in secondary school and also had great difficulty with mathematics, sometimes even to the point of failing, I want to show that you don't have to be a natural genius to study physics. All it takes is interest, curiosity and hard work.’ Starting next week, Erik will be writing about his studies on Fysikum's Facebook and Instagram pages.
