@TH1GUY1324 thats all i listened to

[Geo877]

Very well explained :)

Thank you so much ! This video helped me clarify things easily, and the thing is im only in grade 9 physics and already doing stuff like this. But i know it will pay off. You are a really good profesor, but how do you graph stars ? Because i really dont understand graphing stars since my teacher doesnt teach very well.

@Aljon1000 at any given point in a star's life it occupies a point on the diagram according to it's temperature and luminosity. the graphs are made of a large sample of stars in a cluster.

You are really amazing doctor.

[twigothique]

Aha thank youu.......THIS makes sense XD

[TheKeyb0ard94]

this was helpful but how do you apply it? is it a computer program or can you use it on paper? and do you need a telescope or can you use it with the naked eye?

[Keiaola]

wow.....thankyou soo much....way better than my professor!!

Thank you so much, this video was very helpful !

[SuperhumanChichi]

I like the way your explain things, you are a lot more clear and concise than my astronomy professor. Thank you :)

I think the reason why the scale for temperature is in different way because it follow the scale of colour (OBAFGKM), so its from hottest to coolest.

@prettyboybn

Yes, exactly!

x-axis is not just a funny way of representing temperature and colour. It's just the normal visible E-M spectrum sequence. Short to long frequency.

Nicely explained for laymen.

thanks for the video, very helpful :]
