"Kita harus meningkatkan kuantitas dan kualitas kebaikan. Kuantitas bisa dilihat dari frekuensi dan besarnya apa yang Kita berikan kepada orang lain. Sementara kualitas manfaat ditingkatkan dengan cara meningkatkan kualitas diri, yaitu dengan meningkatkan keterampilan dan kemampuan, sehingga apa yang Kita berikan semakin bermanfaat."

Frontiers and Controversies in Astrophysics

 

Lecture 14 - Pulsars 

 

 

 

Overview:

 

Professor Bailyn begins with a summary of the four post-Newtonian effects of general relativity that were introduced and explained last time: precession of the perihelion, the deflection of light, the gravitational redshift, and gravitational waves. The concept of gravitational lensing is discussed as predicted by Einstein's general relativity theory. The formation of a gravitational lens can be observed when light from a bright distant source bends around a massive object between the source (such as a quasar) and the observer. Professor Bailyn then offers a slideshow of gravitational lenses. The issue of finding suitable astronomical objects that lend the opportunity to observe post-Newtonian relativistic effects is addressed. The lecture ends with Jocelyn Bell and the discovery of pulsars.
