Buy a Coffee for Dr Jozef Kozár


I am independent researcher and author focused on universe. I write books, education materials and free materials for students and public. I am trying to pay everything from my pocket. I believe that education of people can make this planet nice and that people need to know also what is around us in space. You can help support my work and endeavor for the price of a virtual coffee. Thank you!
