How to become pro in  Astrophysics?

In this course you will master the two basics and advance concepts ofAstrophysics. This course is less theoretical and more mathematical. So, you must have at least high school math skills to understand this course astrophysics. This course astrophysics have its own significance in applied and theoretical physics. Many students around the globe are searching this course  astrophysics to understand the math behind astronomy and cosmology.

The length of this course is 5 hours and there are 4 sections. You will starts with very basics and end with the mastery of astronomy and cosmology. Each videos is not shorter and has at least 1 hour duration. However I have given some suggestion to take this course in the introduction video. So, must follow the suggestions that I have given in the very first video.

Moreover, the course is not easy and might be some students will feel the difficulties while taking this course. They shouldn’t worry because there is question answer sections in each video. You can ask me as many questions as you can ask, I promise you that I will give you the prompt response on each of your questions. You shouldn’t not feel that I am far from you. Honestly, it is just like I am sitting just like in the classroom and you are asking me the questions and I am giving you the answer.

The course is fully structured and have varieties of contents. The course has prepared by sequence and series wise. Many contents, famous contents which are being used in astronomy and cosmology has  been presented by me (Instructor).

The course fulfill all the basics and advance concepts. You can apply this course in the research areas of cosmology and astronomy. I feel that this course will attract the researchers and they can apply the mathematics in astronomy and cosmology.

Some of the contents are purely the astronomical where you will learn the documentaries information about solar systems and others planets, galaxies, meteors and asteroids. But some of the concepts are purely the cosmological where you will starts from the line elements of spherical polar coordinates and you will end it with the Hubble’s law of universe.

No doubt, the course is totally mathematical but I have also explained the theory behind the mathematical equations that what they describes and what is their physical significance as well.

Astronomy and cosmology is actually the applied physics of starts, planets and evolution of universe from big bang to today or in the future predictions. This is much interesting if we formulate the theories behind the subjects. And you will get astonished when you will find the theory behind these mathematical equations and I hope that you will enjoy this course. Have a nice day
