This is the sixth lecture series of my complete online introductory undergraduate college course. This video series was used at William Paterson University and CUNY Hunter in online classes as well as to supplement in-person course material. Notes and links are present in the videos at the start of each lecture. To begin with, I chat about the bulk properties of the Sun, and some other interesting factoids. Mass, Volume, Density, Temperature, and other things that relate to the Sun as a whole. Next, I’ll teach you all about what the Sun looks like! Prominences, Flares, Sunspots, Ejections! It's a much more active place than you think. It's also mesmerizing, like looking at a fire while camping. After looking at the outside, we go inside, discussing the core of the Sun and its conditions. The core of the Sun is where all of the action begins. It contains the conditions we find in all stars on the Main Sequence. Next, we look at how energy moves around in the Sun, and take a peek at the basic equations of stellar structure. This section lets us know that one day, the Sun will stop shining. That begs the question of exactly how the Sun shines, and how long it will shine, as well as some of the great questions of 19th century Physics. We'll also see what your smile looks like when you get a Nobel Prize. Finally, I discuss how the Standard Model of Physics was tested, and how the existence of fusion in the core of the Sun was actually determined. This led to two Nobel Prizes, and a lot of dry-cleaning fluid down a deep, deep hole.

And now to zone out and sleep while learning a thing or two from someone who teaches what they're talking about. Thank you, professor

[@MitchKarajohn]

I love your enthusiasm and the way you communicate the subject

[@edd.]

Love your teaching videos!! Great job on the remakes!

[@JasonKendallAstronomer]

Thanks so much!

Every now and then I fall asleep to watching youtube videos--typically 'pop' videos about math or physics/cosmology. More and more often I'm waking up to these series of videos. They don't have the 'asmr' of the finely-produced "NOVA" docs, but damn they're good! Perhaps the most packed AND accessible videos on the subject. . .where even someone who isn't doing advanced studies can pick up ADVANCED information. Thanks so much for these!

[@JasonKendallAstronomer]

Why thank you for the compliment!

excellent.. I only discovered these recently and then all the remakes come out.. I'm overloaded with space.. amazing

3:17:24 That was Paula Abdul :) Another appropriate song for your channel would be neutron dance by the pointer sisters (I was reminded when you mentioned fusion dance).

Another Audio Triumph, Mr. Kendall

It's so fun... after studying your videos I can watch other KZbinrs so much better... you should call out people like ParalaxNick and other people you want to migrate us towards

so good

Hello! You keep mentioning gases in the suns atmosphere. Are they gases or is it all plasma? Thanks!

[@grproteus]

What was that at 8:30? Didn't catch that.

[@iiz67]

It's variable you know.

I find it very interesting that the _only_ people who seem to have a gripe with the whole Pluto thing are Americans . . . get over it . . . you're not special.
