8) Gravitation - From Newton to Einstein
9) Maximum mass of neutron stars
10) Evolution of neutron stars in close binaries
11) Recycled pulsars
12) Tests General Relativity using Double Neutron Stars
13) Gravitational radiation from neutron star mergers
14) Black Holes of General Relativity
15) Super massive Black Holes
16) Universe versus Multiverse

[@ankitvaghasiya3789]

what a great and wonderful explanation by Prof. Srinivasan.

[@meetghelani5222]

Thanks a lot ICTS, I love the professor's lectures. He's a true gem.

[@lengooi6125]

Simply wonderful lectures. The historical tidbits offers insights into out of box thinking that moves science forward. Thank You for posting these gems.!

[@alendominic8320]

This lecture is pure gold!!!! (eventhough i don't understand many of the equations and don't know QM or PDE or anything.....it makes perfect sense how he infers conclusions from each of the equations.)..Really loved it.

[@lutpulla7183]

Excellent presentation! Thank you for sharing it with us.

[@ArbitraryConstant]

excellent talk

[@rexremedy1733]

Very well presented at an above average information density over t.

[@brindhasrinivasan2837]

Brilliant lectures Sir!

[@ianian8022]

Brindha's right Sir!

[@zxwmabcdef5439]

Would it be possible to simulate degenerate carbon and oxygen by using a fission bomb? They could focus the x-rays onto a slug of solid CO2 use the x-rays to crush it.
