- How did Joseph Fraunhofer, a poor glassmaker, get saved from poverty by a prince and then discover spectroscopy (Fraunhofer lines), single slit diffraction AND the diffraction grating? I use primary sources to discover the background and the physics of this epoch making discovery.

Yeeeeah we love you Kathy!
Thanks! ❤️
God bless Kathy for these amazing videos.
These are amazing history lessons done in a very enjoyable format, by a great communicator.
I hope Kathy's work can inspire more young girls to pursue careers in STEM fields...
She's amazing.
Your students (and I count myself as one) are very lucky. Thank you!
I’m honored to have such great students.
@@Kathy_Loves_Physics I love your videos.
Im impressed how well you can explain these topics. I am fascinated not only by physics, but the history of physics. You know.. "how it was discovered?", "how did anyone got this idea?". It amazes me.
Now, I have the luck to be living in Munich and last weekend I went to the Fraunhofer-Glashütte, near the Benediktbeuern monastery where Fraunhofer used to make glass. It is incredibly well preserved! After that I looked on the Internet about more information about Fraunhofer's life, but did not find much. Until I saw you video. So, thank you very much for that!
You are welcome- and I am quite jealous of you for being able to visit his old factory. Sounds fascinating
Wonderfully presented and amazingly informative ..
I just wanted you to know this entire story is basically the first chapter of my thesis. This really helped me conceptualize it alot.
That makes me so happy! My email is Kathylovesphysics@gmail.com. Feel free to email me if you have any questions or if there’s any way I can help you.
@@Kathy_Loves_Physics Thank you for the offer. I was pretty stuck on a logical way to start talking about photochemistry and spectroscopy and this was a great way to start! For now all I need is encouragement. I love the channel it's really great to have someone explain the history of a scientific topic.
Kathy is so enthusiastic and tells a great story. Really enjoy all of her videos.
I love your enthusiasm Kathy. It makes your website a goto for someone who loves what you do. Thank you for being dynamic Missy, Mrs, or human questing being, whatever, thanks.
I will happily be “human questioning person”.
This is a great story, I had no idea! Amazing that his own intellect took him from being an illiterate, indentured 14 year old to making great scientific discoveries, no universities involved.
Loving the movement around the room, it gives better perspective for the painting. Wonderful ‘kneeling maiden’.
I am always in awe of the minds of these scientists.
Awesome timing! I just made a LinkedIn comment regarding the first famous X-Ray picture, an old colleague who does some advance FTIR analysis that's amazing, where is amazing how the whole range of molecular energies situational awareness has developed from two dimensional to imaging that elucidates additional dimensions of information from each pixel. Reminds me with the snow falling today, that I left off on the interferometry and dispersive webcam spectrometer projects using some old CD/DVD/BluRay and HD parts since wanting to control the angle of the disc grating (or maybe later a purchased grating) with the HD actuator and the slit width using the sleds. Thinking with the interferometer design... I still need to determine what I'm going to use as an optical workbench for starters since the COVID isn't helping getting out to the Fab Lab and using the Torchmate to cut some tables. Plus those lenses are so small... though I'm thinking workable for a range of interferometer designs. Thanks for sharing!
I'll comment also since may inspire others to homebrew some upgraded spectroscopy experiments to share for detecting the World mass and energy... though eagerly awaiting finding an old laserdisc player or two since I think those have little He-Ne lasers. Then again... saving up for the HP HeNe or cheaper version kits on eBay will be the expensive and thinking better way. Bummer the university stores are closed too. Oh, well... thanks for sharing Kathy Loves Physics!
We have certainly come a long way from that first photo of Anna Bertha Röntgen's hand.
@@shawnmulberry774 Oh man! Amazingly like each molecular energy has devices that really do more than image. They have the capabilities to make 3D images that depending how you interpret dimensions... contain a lot of information I'm guessing in some circles close to near real time. Sad in some ways the good ole high resolution analog methods turned to digital technologies where the watchmaker or glassmaker mechanical skills seem to be lost... though... gaps are bridged with the disciplines and neat devices like MEMS and other devices are still developed. Yeah, wow... like to have RADARS in space not on satellites that somewhat can do like X-Ray performances through buildings and being declassified. That's just using the marine RADAR range of devices to see radar cross sections of insects. I mean insanely detailed malicious if we let those bad actor bafoons trick, coerce, seduce and manipulate us and worse in unlawful, illegal and criminal ways and means. Glad science and engineering is getting out more online more in easy to comprehend ways... mainly the physics since physics is the science of the math of the phenomena that is everything throughout all time.
Great stuff, as usual. I have used Fraunhofer diffraction to measure the size of small particles for ages, but never knew anything about the man. What a great story! Another inspiring tale of "poor boy made good" to put beside those of Newton and Faraday.
Great video, as always, you're awesome. Thank you so much for sharing your knowledge. Loved the comments at the end, though, the "hit buttons until you're sick of it" and "don't talk about princes while watching The Crown" cracked me up
Thanks. It’s hard to tell in this medium whether anything I say is actually amusing or not.
@@Kathy_Loves_Physics yeah, that's true, it's not like you have an actual audience laughing at your jokes in front of you. But you made me laugh, didn't expect it.
I enjoy very much how joyful you seem when telling these stories, I love science and history, it's so great to have found a channel that shows me both, and very entertaining too!
Thank you.
Thanks for sharing your knowledge !
Your passion and effort bring history to life! It's nice to hear about real world "super heroes" instead of fictional ones.
You really do bring live into the story about physics!
I have a few weeks off this summer. Kathy, let me organize all your videos in a manner that allows us all to "traverse the history" of what you speak of.
That sounds great, why don’t you send me an email?
Lord Kathy. You are therapy to me. Just listening to you.
Thank you big sister. 👏💯
You are welcome little brother.
I think it would have been worth mentioning the Fraunhofer Society, the probably most important German Society for applied science with dozens of institutes. en.wikipedia.org/wiki/Fraunhofer_Society I myself wrote my Master Thesis at the Fraunhofer LBF.
you are the best teacher in the world. keep up your great work.
Wow, what a great Christmas gift to everyone watching. Thank you.
Fascinating! Most notably it is a prime example of talent having relatively little to do with formal education. Maybe this should be prescribed course material for people in the HR department 😀
Hope you are recovering Kathy. God bless you
Just found your channel and watched almost every video. You are doing a great job but I have realised you haven't uploaded any video for 2 months. I hope you didn't quit
Thanks for checking in - I’m not retired, just hurt my back and couldn’t make a video for a while. Just filmed my video on helium today and should get it up within a week (crosses fingers). Hopefully, it will be worth the wait. Cheers, Kathy
@@Kathy_Loves_Physics Kathy, if you are making video on helium, you will have a hi squeaky voice. I would say get well but that was 10 months back. Stay well.
Thanks for bringing these unheralded characters to life. (I'm going to send you a copy of my book - I think it will appeal to your ways of thinking.)
She's amazing.
Great as always, thank you.
Thank you for uploading. I got the opportunity to witness a rocket launch in 2018. Memorable experience. I shared a pretty cool montage of the journey to my channel.
You’re hilarious. I won’t be waiting for Princes anytime soon, thank you
Good plan, they are unreliable
Love your videos. I prefer the crossover music on this one instead of the “Lectricity” vocal that i’m Reluctant to say i find annoying. Nevertheless keep it up.
The sound is very good! Merry Merry to you and yours Kathy.
Lol! "whose name has been lost to time and sexism". What a great line.
Thanks
I love your channel. Keep it up
Hi Madam.
I have seen your Video of live communication to India.
It was very nice video.
Very big video full of Information.
Every thing ...... every thing you taught us. All summary in one single video.
From amber to todays technology.
Jagdish Chandra bose.
Semiconductor crystal growth.
Your liking towards James Clarke Maxwell.....
All the this things in video was awesome.
You should also post that video on your TH-cam channel so that others can see it too.
.....& by the way, Nice Hair Style in this Video.
Keep going & keep growing.....!
So good! Really these videos are so good.
recently started watching your videos its nice !!
Glad you like them
I've noticed that sometimes I click "like", only to find when revisited--NOPE- it's not there Thanks YT.
Awesome video. Nice 12/24 blouse too.
I can't wait to read your books.
Me too!
Just was inspired by a TH-cam AI suggested video titled "Henry Moseley’s X-ray Spectrometer" and that got me thinking you can do some videos on X-Ray and Gamma Ray Spectroscopy and the related in detail each or not too. Muon Spin Spectroscopy would be something interesting also. Figured I'd note for inspiration since is on my mind. Wishing a bountiful, healthy, safe and Merry Christmas and Holiday season and beyond.
Looks like no NMR has been demonstrated either. Maybe something regarding the electromagnetic spectrum and magnitude of influence of molecular energies in the ranges in the EMS related to spectroscopy disciplines? Probably would be an awesome bridging of a bunch of videos too like as a future project. I guess spectroscopy and chemometrics still get's me excited... plus now with the snow on the ground I'm forced back inside to work on indoor projects. Amazingly, I found a 3/4" large steel plate with reported as (though they look smaller) M10-1.5 60mm spacing drilled and tapped holes at a great price for an optical bench candidate. An offer was made and I'm going to accept. Amazing timing!
Excelente vídeo like always.
Very interesting. Thank you!
Thank you for bringing me another great German scientist closer. Like Heinrich Hertz he also died too young.
PS The US pronunciation of Fraunhofer is perfect and better than most Germans do. They say mostly Frauen (Woman) - Hofer 😉 because thinking of a Woman.
I love These. stories about known and in this case an unknown astronomy . 🎄🎸😊
Merry Christmas Kathy
Loved it
thank you.
I kept feeling like the name Fraunhofer is familiar to me from some other topic. Found it: there is an audio coded names Fraunhofer.
Thanks
amazing
Sprb Kathy❤️❤️❤️❤️
Proving one does need much formal education to discover a new phenomenon or to have an inquiring mind.
Auckland NZ.
Happy New Year Madam
I think F is a bit of a hero in Germany. There's a Fraunhofer Institute at least...
I recall hearing Newton was the first to reportedly hold a prism up to a telescope, but didn’t pursue it…. True? Anyway, GREAT Video!
Nice video.
If Joseph Fraunhofer is the father of modern astronomy.
Is Galileo Galilei father of classic astronomy?
Is Zacharias Janssen father of biology?
READY....? LETS GO....!🙂👏
Mam i have a request to you.....mam please make a video on history of IUPAC ... there is no any proper video on TH-cam about this topic
Fraunhofer the father of MP3
your videos are cool
Please make more
Cool videos
Türkçe alt yazı ekleyenilir misiniz abone oldumda?
Thank you what is your next project
Working on history of helium and then maybe why Schrodinger hated his cat.
40k people is a small city today but in 1801, New York City did not have more than 30k people.
He gets buried alive and then his life gets better. Poor guy.
Buttons!
Alexander the Great, Charlemagne, and Genghis Khan were all princes when they did their thing.
Maybe its better to have princes throw parties and such. They get ambitious and we end up at war.
Great video but just because we don’t know his wife’s name doesn’t make it sexist I’m a window cleaner no one is gonna remember my name
Of course, the Frogs pronounce everything as it it were in Frog, so... whatever.
Just call me next time for pronunciation help...please... :-}
