Sound Spirals are part of an ongoing project attempting to interpret sound in a physical medium: sculpturally, mathematically, and irreversibly. They demonstrate different processes for creating data visualisations of recorded audio in the form of 3D printed sculptural art using open source programming tools and audio software (Processing and Audacity) and contemporary 3D printers including the...

One of the post-Keplerian (PK) parameters determined in timing analyses several binary pulsars is fractional periastron advance per orbit kPK. Along with other PK parameters, it used testing general relativity once translated into precession ??PK. It was recently remarked that ? PSR J0737–3039A/B may be to measure/constrain moment inertia A through extraction relativistic Lense–Thirring ??LT,A?...
