Photoelectric Effect: History of Einstein's Revolutionary View of Light

Photoelectric effect equation is important because Einstein derived it from a revolutionary view of light. This is the story of how wave particle duality was first created using primary sources. Check it out!

Excellent videos Kathy. As a physics teacher with a deep interest in the history and philosophy of science, they really help to bring the subject alive for my students. It's great to see references to the original papers too, something that most other channels neglect.

No, You Did Not Mess up. You are a Fantastic Teacher. Its Hard to Imagine that how much time and effort you had given for all your research and telling us all the story.

[gckoenig]

I just discovered this series and I love it! The integration of the personal life stories, the social and economic environment of the times, and the contemporary research and papers put out by others, all add to the value of what you’re presenting.

I have always found it easier to absorb a physics theory once you know a bit about why/how/when it came about and what was the previously leading theory.
I cannot but think you are helping a lot of physics students with your storytelling.

please stop
making excuses about "messing up. ". you're the most fascinating science reporter ever and so much fun to listen to. The human connections behind all this science work is truly what life is all about . please continue "messing up " or not
And i vote not messing up !!!
As you breathe life into the scientific world .. we all appreciate you for that ❤

This entire video series is like attending a friendly delightful informative course on the history of electricity and physics. Absolutely awesome. I think kathy had an annus mirabulus when she up loaded these videos and finally this corona lockdown will make her famous. As more and more people watch and share the videos.

The man is the definition of thinking outside the box. That miraculous year when his mind was razor sharp. He looked at things, thought deeply about them, saw some logical inconsistencies, and then, saw what had to be true, no matter how odd it seemed

The high quality of your videos shows how much work goes into them. Thanks so much for creating them!

[subcdriller]

I love your presentations Kathy!!!! They are an enjoyable and informative journey into science and history.

Trust me, this is the only channel that I subscribe in my entire life. Always give me new knowledge. Can't wait for the next videos.

[jon]

You do such great work, Kathy. I always leave a little more educated.

[Roberto-REME]

Outstanding video Kathy. You made it interesting, easy to understand and your narration is superb. Well done!

[boyanfg]

A big thumbs up! This is the best explanation of the photo-electric effect that I found on YouTube. A thrilling and entertaining story especially with the historic background. Please continue this series.

[nirajabcd]

Your channel deserve much better recognition like the other popular science channels. I think will happen in due time.

[mjsnosker]

Youtube must be broken, this channel should have 100K subs.

[ChucksAstrophotography]

Wow, a lot of information here I never knew. Excellent. Subscribed!

[mokoepa]

I wish the video titles were numbers not on the thumbnails but the literal titles themselves just so one doesn't have to fish for the next videos...


I'm addicted to your content... Very outstanding, Thanks a lot.

[riodasperolas]

Hey Kathy, it’s amazing watching you talking about Physics’ history! Like a thriller

[lamequemaciel]

Under quarantine days, my professor (about structure of matter) often shared your channel. And I appreciate.

[deepakbiradar]

Its an excellent video. It's pleasure to see references of the original papers. While watching this video I was feeling like I am in that era of Albert and Plank.
