The Origin of the Elements

But this presentation is the best I have ever seen, as it is constructed so well that even non technical people can get a fair understanding of the whole process. Very well done.

Being an expert in your subject matter is one thing, condensing and conveying all that information in an interesting and engaging way takes a true master. Thank you Dr Murphy.

I'm 77 and I picked up all this information in bits and pieces over the course of my life and managed to put it all together, but it's a pleasure to see it presented here in such a clear and comprehensive manner. Dr. Murphy brings it all together and explains it with such beautiful simplicity that his lecture is a total joy to watch.

I'm an non-degree person. But what I think is that it is presentations like this that raise the level of knowledge of regular, everyday people like me to a whole new level. I've personally studied astronomy for years, to the extent of my own understanding, but this presentation just gave me a whole new Kick-Start! Thank you! :)

[@DimljenaRiba]

People usually study for two reasons: 1.to get a "good" job or 2. Because they are interested in the subject. In most cases people try to steer their interest toward a subject that pays off. Graduating from university usually just means that you acquire a certificate that you possess a certain amount of theoretical knowledge. Of course every degree is structured in a way that it forms a certain unity of knowledge but my point is something else. If you are interested in a certain topic a degree means nothing. In most cases you will learn on a deeper level and with more joy if it's self-tought because you don't need to undergo the stress of an exam. You won't get to be scientist without a degree but let go of the term "expert". Just go for it if it's fun! There is so much to discover. I couldn't let a day pass without new knowledge - except for times of meditation which is my next goal.

@@karenmann4825 : I’m old enough to remember a time when we had to store our knowledge on crushed trees, moulded into slivers of wafer thin pages, upon which we imprinted that knowledge, using dark, carbonised substances to stain those pages, which we commonly called, “ink.” We had to bind them together and protect them with special covers, which we etched descriptive pictures onto. They were burdensome to carry, stained and torn frequently and usually outmoded, often on the same day that they were printed. However, they remain unhackable, fixed and smell uniquely comforting to those who love the old ways. So, they have their merits too 😉✌️

He was phenomenally clear with his diction, and brilliantly offered just the right emphasis at times that brought a level of gentile excitement completely captivating my full attention. Truly this is wonderfully refreshing, and quite amazing to me especially because I already have a passionate and thorough knowledge of the entirety of this presentation. Even though I majored in Biology with a minor in Chemistry, I have always had a major thirst for Physics, Astrophysics, Cosmology, and Quantum Mechanics... Furthermore, even though I finished college in 2003 I have continued to learn (those topics of physics) almost daily ever since. Especially since the invaluable gift of KZbin.

I learned more from this one-hour lecture than I did from a year of High School chemistry! And I did it without falling asleep in class.

[@stacybroadnax3049]

I said the same thing!

[@jeffreykatsman291]

This is amazing. Sometimes I get bored after some time just watching vids with a prof speaking but when you make it this interesting and add those images in between it makes it truly enjoyable to keep watching. Good for you. Please keep making more of these in this style. I look forward to it.

Amazing lecturer. No script.

Mind blowing! One of the best lectures I watched on KZbin so far. This lecturer is true genius. I wish he will continue and make another lecture - there's a lot of the interesting stuff in today's cosmology.

[@nadmey9099]

Fantastically explained. Simple and easy to comprehend.

I thought it was a neutron cascade event from the collision of neutron stars and black holes that created most of the higher elements. I know supernovae did this, but I thought that that was not the prime creator of these elements. Regardless, a truly excellent lecture.

@@kurtbjorn That's knowledge that wasn't known until years after the talk was given.

How about the fact that earth's magnetosphere that protect us from Sun's UV(luminosity) & oxygen to escape into space?

[@JeffersonLab]

@@edthoreum7625 Nothing that you said is a fact. The earth's magnetosphere does NOT protect us from the sun's UV since you can't use a magnetic field to block light. Hold a strong neodymium magnet in front of a light source and you see that it does absolutely nothing. The earth's magnetosphere helps protect us from the solar wind (charged particles which are 'blown' out from the sun) and the ozone layer protects us from the sun's UV (the ozone molecule absorbs UV light).

This was a fascinating lecture! I am humbled to learn that I do not "own" my atoms! Astronomy has opened my eyes and my mind.

[@stanjarmolowicz]

yeah , you just borrow them if you extremely honest person ..however you can still them when nobody see and credit companies won't even notice ..they are so busy printing money out of thin air than i'm afraid that some day things get out of control and they accidently will create antimatter ...then wee are in trouble ..we won't end up in nebula ..DARN !

Best astronomy lecture I have watched; a lot has changed since 4th grade; I'm working 0n 82yr. Thank You, Dr. Edward Murphy : = }}

[@subramaniamarumugam2433]

Thank you Dr. Murphy. Very interesting and informative I will recommend it to my family and friends.

[@johntoler2235]

I should also like to give accolades to the lecturer. Many interesting aspects of life and the universe were succinctly described and put into perspective.

[@mariafinnerty7184]

The best explanation of Life, the universe and everything.......to date ,Thanks

What a great teacher. I learned a lot and enjoyed the time I spent doing it. And that combination has heavy Element raritivity. A fact that I now know, largely in due, to watching this video. Thank you.

[@peterandersong]

Wascally wabbit!

[@jefflyon2020]

no matter how incredibly intelligent and gifted for science a person is, the spoken delivery of a lecture ( tempo, volume, pace, and clarity) is VERY important and few people are also inclined to be good at both. This man is pretty good, Jason kendall, who does a series of lectures online is excellent, and the the two professors, or scientists who strike me as the smoothest are Michio Kaku (hope i spelled his name correctly) and cool worlds lab and DDTV narrator David Kippling ( sorry if i flubbed names here), who deliver and set a calming, yet exciting pace and tone which enables folks to learn, YES! learn! Amazing effort here and there and everywhere to those who aid us mortals in education.THank you.

[@znbr1]

Such an important issue, and bright explanations, that I was stunned. Dr. Ed Murphy is a best scholar and an important lecturer!

[@async03]

I´d love to hear this same class by the same man in this year, after all the new discoveries made after 2012, it has changed.
