The world around us is made of atoms. Did you ever wonder where these atoms came from? How was the gold in our jewelry, the carbon in our bodies, and the iron in our cars made? In this lecture, we will trace the origin of a gold atom from the Big Bang to the present day, and beyond. You will learn how the elements were forged in the nuclear furnaces inside stars, and how, when they die, these massive stars spread the elements into space. You will learn about the origin of the building blocks of matter in the Big Bang, and we will speculate on the future of the atoms around us today.

Speaker: Dr. Edward Murphy, University of Virginia
Date: November 13, 2012

    I learned more chemistry from this video than I did in my entire life so far.
  • @QU1RKONE
    I stumble across this video every few years, I never tire of watching it.
  • @zs2839
    This video is a perfect example of the power of a great communicator. This man took an unbelievably large amount of information and presented in a manner so clear and logical that even I was not able to understand it. And he did it in under an hour.

    I heard this lecture about 20 times , and probably will hear another 20. Mr Murphy is awesome

    I passed my engineering now I don't have to do anything with origin of elements But for the first time video made me feel that I learned something valuable in my life. I never watch nearly hour long video without skipping at least 10 second but this is first time. Great work sir..
  • @vike2168
    I've heard so many speakers throughout my life so far and you Sir, are one of the best. Well spoken, clear, no mistakes, loud, not too slow, but not too fast, just a joy to learn from. Thank you.
  • His presentation skills really are exceptional. No pauses and great flow. You can feel his passion. Thank you.
  • @johnpless2954
    This guy could read a restaurant menu, and I would sit here and listen to the whole thing. There's just something about the way he presents things and his enthusiasm.

    When I was in school in Perth, Australia in the 1970s I was lucky enough to have a science teacher with the same sort of passion and enthusiasm as this man. I envy his students who not only get his passion for his subject, but the technological advances that give so much more information than we had back then.
  • @Katiesarabians
    What a super teacher. If all could be like him, people would learn even if they thought they weren't interested.
  • This was an exciting journey and I'm glad to have been a part of it. The way he went full circle on gold was something to marvel at. If only my science teacher taught me like this 😭
  • 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.
  • @craneforever
    an age-specific version of this should be the first lesson of every chemistry class
  • @JikiTheShaman
    This was honestly one of the most interesting lectures i've ever heard, so , thank you for uploading and i wish my teachers back in the day were like that.
  • @berndheiden7630
    I am 74 y/o, have a doctorate degree, it is 04:30 at night and I am thrilled to have learned so much in just one hour that I have not been told in all of my life! Learning is the greatest thing in life and giving children this understanding is the real challenge for educators. They can find out every factual knowledge in minutes nowadays, but to start that drive to want to know something new every day is the real take home message that school owes to the children!
  • @plantplants3036
    Dr. Murphy is a WONDERFUL teacher..I was actually falling asleep in bed when this interesting video appeared and woke me back up held my attention all the way through.
  • An excellent communicator! The speaker is impressive! Although I already knew most of this, I still learned many details that I found fascinating. It was a well-presented lecture that lets the gestalt of atom/element formation be readily understood.
  • @1960markN
    I have always lamented the fact that I know so little about chemistry. This is an amazing lecture--very clear, easy enough for an absolute novice like me to follow, but full of information. Thank you very much, Dr. Murphy!!
  • @JazzLowrider
    I've never fully understood the the periodic table of elements and astronomy, but this great teacher makes it a lot easier on my mind, a presentation like this is very important to open new minds to science and discoveries, Thank you Dr Edward Murphy you're a gift to students i wish i had a teacher like you.
  • @Gobio2
    I know the subject since long but listened with enormous pleasure, this is one of the best lecturers I have ever heard in my 65 y life
