Same! Chemistry is my weak spot and this guy still explained everything perfectly

Respect

Why should I fear death when I'm made of atoms 13 billion years old?! 😊

For real this my second time watching..He explained it so clearly 😅

I'm 74 and a chemical engineer. I sent this to some relatives and friends and titled it "Putting it All Together" so I totally agree with you!

I'm your age and continue to be amazed at everything that is known now that wasn't known when I entered college initially. The helicopter on Mars is my immediate favorite; waiting for what we learn from the Webb telescope.

My coment above.

73, standing by. Roger, wilco.

Agreed!

Prof, I'm sorry I couldn't memorize the table.

That's cause it's taught in physics classes. Gotta love the arbitrary dividing lines we have between disciplines

In 1977, a complete understanding of the periodic table was required to pass as well as the knowledge of the various bonds

You didn't get bored by the first 57 minutes?

@@rizdalegend One can appreciate and enjoy someone else's presentation, even if one has complete familiarity with the information being presented.

Just imagine your atoms will be mostly in the rigs around the nebula. I guess you can save on cremation? And all of this applies to me too, of course.

Age is no barrier to learning. Look at the people in their 90s going back and getting university degrees :) Even as we age, our neural network is still capable of being trained - i.e. learning new things :)

i also started elementary in 64 this teacher or professor just explain everything that a 3rd grade could understand actually we learnt it in 7th grade he explaining here wish teachers were everywhere so intelligent like this man..

80 here.

You are not an old woman, you are young like all of us. We have many star cycles ahead of us...

Well said Henry , I agree , it was great 👍

@@danielwilson6529 Yes, it was excellent.

@@danielwilson6529 my j

Majored in phys and chem minored in maths as Americans say. But these fields are huge. So I come accross topics like this vaguely and know about them but never looked into them. The amount of interesting stuff on UKposts that is explained means I never get to watch propper TV. I have friends who left school early who would understand this it is explained so well. I know the physics could go deeper but the chemistry is beautiful

Just realized: a matter has its own dance, we came uninvited.

Wow!

I never liked learning when I was in school. Now that I'm out of school. I can't seem to learn enough.

Well said!

@@aaaricmondroofing1703 Well done! You've broken through! Hey, isn't it great to chow down on the internet for all the mental food you can eat, and enhance your life with it every day you live?

learning: Yes usurping power at all cost: no one should be allowed

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.

a non degree person :)

You will one day make a great physicist, Sheldon!

Even if you do it online or by correspondence, start on your degree now! You will live a happier and fuller life and benefit those around you.

@@DimljenaRiba don't you feel badly for people who have no intellectual curiosity?

Not exactly pure gold, a few other elements were also discussed.

I wonder if the pun was intended haha

How funny. I am 53 years old and think the EXACT thing. Today’s youth are so lucky. Sadly, they use this technology to play games and socialize. When I was in school the only resources were outdated encyclopedias. 😀

@@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 😉✌️

@@karenmann4825 The harder you have to work for something, the more you tend to value it. Kids today have a WORLD of knowledge at their fingertips, yet don't seem to care about it at all. Awful.

Pat yourself on the back. You are here now, and you are learning. I have been learning about science since I was a child. I loved science in grade school, high school and college. After graduating I never stopped learning. I knew most of the stuff in this lecture already, but it’s still fun to hear a differently explained perspective. I am 75 and have the same attitude about science I always did. You have the bug now, so keep learning.

@@karenmann4825 You "Think the EXACT thing"? Exactly!

Do you really see him on the bus every day? Or did you?

Thank Hans Bethe and Fred Hoyle. They figured most of it out.

Learning

And now for the fun part: Much of this is wrong! In this short 8 years, we've discovered neutron stars and "hypernovea" resulting from neutron star mergers -- which turns out to produce more heavy elements than supernovea. en.wikipedia.org/wiki/Neutron_star#Neutron_star_binary_mergers_and_nucleosynthesis en.wikipedia.org/wiki/Nucleosynthesis#Neutron_star_collision

@@firstnamelastname9918 Was trying to figure out the same thing just from a reasoning perspective , most everything seems to be figured out , accounted for or presented in that light when in reality quite the opposite may be true . If a scientists lies or makes a mistake no one goes to jail ,the only thing one has to care is peer pressure ,if no one has a better theory the last one can stand not because is viable but for the lack of better knowledge. At the end of the day we may listen to likable stories that have traces of truth in them in total disagreement with present scientific community .

beautiful knowledge... I like how you put that !

Yes.

@@paulwalsh2344 yes.

Yes.

This. Superfluid, superwell articulated. Rarely you see someone talking practically without stumbles or 'uhms'.

This has been the most informative, lucid and enjoyable presentation of cosmos I’ve ever heard. Thank you, Dr. Murphy!

It's difficult to retain all that you learned all that time ago (:

Absolutely correct

great lecture!

Agreed to all of the above. And then there's the fact that he didn't use notes, a laptop or a prompter.

I'm so glad to hear you say (type) that, good for you. I'm 52 and I've spent all my life studying all forms of matter, science, philosophy etc and I now have even more questions that need solving. Seek knowledge my friend and you will never be bored.

Yes lots of Q Question need to be answered

Ask away and I'll try to answer what I can. I'm no professional, but I'll try to provide enough detail that you can follow up with your own more thorough research. Hearing the same idea explained by different sources was a big part of my attempts to understand science. Still is, I suppose.

What is your favourite element?

Well, we have to leave some things for you kids to discover.

Agreed

THUMBS UP!

I am equal condition. Very good. Edilberto Pedraza

I''m your age and had the same experience of using school's PCs and didn't own my own until several years after graduate school. Yet, I learned everything discussed in this lecture in Introduction to Astronomy in my sophomore year of college over forty years ago. Didn't you?

Don't believe everything you hear just because they(it) sound(s) right.

Jose: I am 85 yo , barrio raised "young man" who has always loved science of all kinds and was a nerd but we'll accepted by my peers. I owe becoming a degreed social behavioral scientist and clinician slowly because I worked to raise a family while taking advantage of educational opportunities available to me in practical and economic terms. I earned a BS , then MS, and finally a DSW all while working and on scholarships and grants of different kinds. I am grateful to all the free libraries in my life, the second hand book stores, and many helpful kin, neighbors, friens, and professors in my life. Most of all I owe great thanks to my wife and kids who always had a dad studying something. BTW: We were married at age 19 just out of HS and are still happily married with grand and great grand children. Long story short is I feel we have things in common. I am retired from clinical work in corrections mental health and still do ad hoc research on violence mostly from video data uploaded to thecWEB by people worlwide. Well, I got to go and close by saying "Only in America." P.S. (Please excuse the typos and gram errors as I keyboard my posts)

Well, Jose, I only have one STEM degree, B.Sc. Chem, and I'm 65... one of the issues I have with this Universe I'm in is that I won't live nearly long enough to learn everything that I want to learn. If only there was a way that I could extract one minute from the lives of the millions upon millions around the world who fritter away their priceless, irreplaceable time watching mind-numbing drivel like "Top 10 Russian Car Crashes 2018", "Wallymart vs. L'Oreo Pesowhore Red Lip Gloss Showdown!", and/or the Denali-sized midden heap of degenerate autotuned nursery-rhyme-level "lyrics" w/synth called "music"... alas...

Same...
