Beautifully explained. You do make these subjects like Spectroscopy, which are not particularly exciting the in classroom, come alive. Spectrosocopy was never my strong point, but I am now going to do some searching. I will need to go through it again slowly. But I always watch your videos again after a few days to make sure I have missed nothing. Another fascinating story of real humans and not the faceless boffins they so often seem in the classroom. This story is heartwarming. How wonderful that the two men became friends and acknowledged each other's contributions. Would this happen today? Thank you for another wonderful video.

Poor Child! Hurt my back too doing yard work. Sitting and sleeping mostly okay, but even rolling over in bed is
painful. Heaven help you when you have to make a mad dash to the restroom! Yikes! Love your exuberance and info
you have in your videos! Although time wise they are long (no that I'm complaining, cause the information is worth
it, it doesn't seems like they are long because of the entertaining manner, information, references and photos you
use to blend it all together. Back to the BACK! I hate standing up after sitting for more than 5 minutes! The Pain!

That was outstanding presentation. You held my attention. This was fascinating. Interesting I have worked with biomedical engineering and instruments that do quantitative blood serum chemistry ie total protein glucose LDH. Two types of chemistry is done end point or time lapse the reactions are available n a cuvet alight source is pass thru then a filter wheel with filters from 340 to 610 nm then by how much of the wavelength passes and detected by photomultiplier and using Beers Law the amount of that blood chemistry now is known.
Science is fun

I can empathize and sympathize with your back pains. As I also have experienced the agony of sevre back pains, and spinal surgery to alleviate and eventually eliminate the pains; at the cost of being approximately 3/4 of an inch (1. 91 cm) shorter. In conjunction with my ageing body, as I was in my mid 40s at the time in 1996, I'm no longer two metres tall. For Adonai's blessing of time can also be an onerous taskmaster. I'm relieved to see your improvement, as much as for your own wellbeing as for the insight you give us.

Most commonly hurt backs don't last forever. I was glad to hear that. I have a massage chair, common in the country where I live, and this has always accelerated recovery. You might think about it. On another note, I found out, as a physics teacher (a long time ago, that the students perked-up a lot when I threw in some history or anecdotes about scientists and they knuckled-under much more readily after. Thank you for your research and accomplished presentations.

I can't tell you how much I love, Love, LOVE this video. It was your video on spectroscopy that first drew me to this series, and now I get an even greater expansion on that. I have such a feeling of wonder and discovery, like I get to experience the eureka moment right along with these scientists. The sodium in front of the lamp just blew my mind, I was like Whoa! Your passion for this stuff is so contagious. Thank you so much for what you do!

Glad you're doing better - I've been there. Your videos are great and this one was one of the best. Like most chemists, I often have no idea about the history behind important results in physics and chemistry that I use almost every day. The history is not only interesting, but helps tie the various parts of science into a logical framework that aids in understanding and retention. Hope that makes sense - I'm definitely not a writer.

I have been binge watching your videos for about a week now. I am finding Science much more interesting and easier to understand when explained through a historical perspective! My dad has a PHD in organic chemistry and taught it at the college level. I did not inherit the ability to think abstractly and it is exciting to have a better understanding of some of the things that seemed to be intuitive to him.

I always wondered what the role of the Sun was in the discovery of Helium by spectroscopy. But now I understand that heavier elements fall back to the proper Sun, whereas above the chromosphere only hydrogen and the at the moment unidentified Helium remain and are observable.
So the Sun attracts the heavy elements by gravity, leaving the light elements.
Thanks!

Thank you for an interesting video, glad you are feeling better. Here's an idea. the spectrum is linear in science and the color wheel is round in art. So, is the color magenta seen by the eye only when it detects both blue and red light, or is there a photon that caries a magenta color and that the eye can see?

Of COURSE the Scientific Journal, Nature, is famous. It was the 1953 Nature article, DNA: The Double Helix, published by the British Scientist Watson
and Crick, that birthed a brand new science; Molecular Biology! Molecular Biology and Biochemistry are at the very heart of today's Bio-Tech Science Labs!

Fraunhoffer lines only support a hypothesis that in this case, the sun is made of helium. Scientists still need to confirm that hypothesis! The Fraunhofer lines could be a result of light passsing through the atmosphere. So the sun could not be made of helium at all but helium is present in the atmosphere.

great to hear about this big people, there are not that much videos about them even they very important, Their work is mention in books, but take time to search and study, so thank you for fast introduction: -) and I hope you feel better now

I love this mixing of physics histtory and physics accuracy. Good job, very well done. I did know how helium was discovered, and the very particuliar story of Norman Lockyer, who had also been the creator of the Nature magazine.

Just watched your video (you produced it over a year ago) but may I offer my belated condolences on your back injury. I have endured lower back pain for many years. Wouldnt wish it on y worst enemy. You are the greatest.

when you're not making videos, are you a teacher at any academic level? you have SUCH a knack for it! would love to have a professor with the clarity and enthusiasm you possess when i go to college in the fall.

Great video, thanks. I'm a chemist doing spectroscopy, and its great learning this piece of science history. I'm also recovering from nasty back pain. thanks again!

Hurting your back stinks. that's why jumping toddler just head budded me in the head. I'm barely awake and this kid keeps jumping like nothing happened.

The only thing that could have made this better would have been to use helium to make the squeaky helium voice for every mention of the word helium.
