Often seen as punk's poppier younger siblings, new wave artists often shared radio airplay and record-store shelves with the more aggressive music. As you will see in the below list of the Top ...

Space communication finally enters a new era For most of space exploration’s history, missions have relied on radio waves to send data back to Earth. Although reliable, radio waves have ...

The shock polar analysis using modified shock relations for a stiffened gas is used to elucidate the refraction patterns. A regular refraction pattern with a reflected shock wave and a bound precursor ...
