thank you so mutch this questions is very importante to the brin for can understand the truth of the BIG BANG so MR i have some ansewrs about the questions whish we made it in the cours the first like we know the Universe is coming from the BIG BANG it was so small like the ball and it become like a bombe be cause ?

so i think it burst because inside it we have a new stars which was born with another planets so this new compositions doing a presure insid it because of this ball exploded to give us the universe so this is my theory about the big bang MR i have another about how the planets formed and the stars to so thank you so mutch about your cours Mr i'm a student in hieght school of Morocco and my name is KHawla

Very interesting and very well presented. I learnt a lot and am grateful to The Professor, University of Tokyo and Coursera.

The only (dark!) matter preventing a five star review is that

the Quizzes could have been more finely tuned. They were either too easy or too difficult, the latter often because numerous responses were being demanded within one question. The html is failing in some of the quizzes making them illegible, so one was compelled to guess.

This course is very nice, just needs more details in the lectures to explain some difficult points in a simple way. And the homeworks could be much comprehensive to help students understand the rational of each theory. Although this could require adding more weeks but up to 8 weeks is worth doing as this course is essentially taken by students with research goals (like me). I hope we can see some improvements in this course year.

I really enjoyed this course a lot. However i am not familiar with Math, i could pass this course with 92.8% and for me this high grade.

Thanks a lot for Tokyo University and Prof.Maruyama who exerted a great effort in this course , and Also i wanna thank Coursera Team too, because made this course available to students who live in arid countries.

This course is interesting and well presented. The lecturer injects humour as well as a sense of curiosity into the topics. However, I would have liked to see more mathematics and derivation of justifications of theories. Much of the material was presented as mere facts or observations with little attempt to show reasoning which leads to the conclusions.

Clever questions and interesting material. Course lacks real teachings and real material in step by step lecutres. It is more broadly made lectures to inspire interest to the given area and institution not a teaching of fundamental underlying knowledge, more like a recap on the current state of astronomy.

Not a bad course information is always new and not too repetitive in most cases. I give this 4 stars out of 5 course because this course is easy to understand and not frustrating. The only thing is that the videos are sometimes too much or too long but other then that a pretty great course.

Great overview of some of the fundamental materials of the universe. However, some of the equations discussed could have been explained more clearly. Nevertheless, a great introduction course that I would recommend to anyone with an interest in physics or astronomy.

A very good course to begin with astronomy. The amount of information is really good, but being in 2020 the information has become old and there are a lot of new changes and progress in the field of astronomy. But even then it helps a lot with a lot of knowledge.

A great review of current advancements in physics presented in a manner comprehensible to people with basic physics knowledge. Only issue was with some slides which had text in colours which was difficult/impossible to read for my type of color blindness.

A bit too much math in the questions, although it seemed (in the videos) that we could skip it. I'm very visually oriented (and also a MENSA member), and I would have explained more with graphics. Or at least not have to much 'equations' in the questions.

For beginners i do not recommend doing the optional questions. However, the general idea of the topics are well explained, though if you wish to learn more on the topics such as anti-matter/higgs boson/cerenkov radiation, you got to read up by yourself.

The Lectures give a good introduction to the subject to someone with very little exposure to the subject. Can be taken by anyone with inquisitiveness to learn something new. Professor explains everything very clearly and in an easy to follow fashion.
