I love this , thank you !!!!!

You’re welcome

[@manasbhanwar7294]

Very nice explanation.. but can you make videos on the topics of the book "Astrophysics is Easy".. because your topics are somewhat similar to it? 🙂

you are the best !

High praise 🤓. Thanks

Wonderful. You're very articulate professor. I need to know how we are able to fix 0 right ascension? A complete technically detailed video is requested.

This is so much better than my teachers. Also the fact that his accent sounds like he's from Australia, which I also am used to hearing (as I am also Australian), so that makes the explanation even easier to understand.

How to calculate brightness due to visible light only?

[@PhysicsHigh]

In essence it is the area under the black body curve for the range of visible wavelengths
