Basics of gravitational-wave emission from binary systems

I recently wrote two introductory articles (one in English, one in Polish) about the basics of gravitational wave emission from inspiraling binary systems:

• Distance measurements from the gravitational-wave observations,
• Rzędy wielkości, skalowanie oraz ,,Newtonowskie intuicje’’ dla układu podwójnego emitującego fale grawitacyjne.
