Superb encapsulation. Thanks! This maybe a forum to tackle the following: At 26'30" in the first video linked below (Pasco Scientific instructional about their speed of light apparatus), mention is made of the photoelectric effect and how it can now be explained using QM applied to the atomic structure without recourse to quantization of light; these guys sound like they should know what they're talking about so here's my question: "is the PEE still the sine qua non of light quantization?"

Can you do a video On physics of startrek deepspace nine

How does a light packet capable of causing an electron to be ejected qualify the light as a particle with no mass?

New technologies, new research tools. BIG SCIENCE doesn't want to eliminate the *BIG MUD* of noise in fundamental optical experiments. WHY? Let me suggest for schoolchildren and students on one's own to measure the Universe, dark energy, black holes, etc. To do this, I propose two practical devices. «laser tape measure *+reference distance* 1,000,000 m”» and «Michelson-Morley HYBRID Gyroscope». I am writing to you with a proposal for the joint invention of a HYBRID gyroscope from non-circular, TWO coils with a new type of optical fiber with a “hollow core photonic-substituted vacuum zone or (NANF)” where - the light travels 250000 (In a laser tape measure, the length of the optical fiber is fixed at 1000000 ) meters in each arm, while it does not exceed the parameters 84/84/84 cm, and the weight is 24 kg. Manufacturers of “Fiber Optic Gyroscopes” can produce HYBRID gyroscopes for educational and practical use in schools and higher education institutions. Einstein dreamed of measuring the speed of a train, an airplane - through the Michelson-Morley experiment of 1881/2024, and only then would the experiment be more than 70% complete. This can be done using a fiber optic HYBRID gyroscope. Based on the completion of more than 70% of Michelson's experiment, the following postulates can be proven: Light is an ordered vibration of gravitational quanta, and dominant gravitational fields adjust the speed of light in a vacuum. you can make scientific discoveries; in astronomy, astrophysics, cosmology, higher theoretical physics,... (We are not looking for ether, we will see the work of gravitational quanta) The result is a «theory of everything» in a simple teaching device and a new tape measure for measuring the universe.

Great video. I always look forward to new content on your channel!

Oh, and of course, A COMMENT! 😂

One may think everything was easier back then, discovering things was easier etc but it is simply not true, they were also struggling to find good hypotheses to test. It is never easy.

Great content

Thanks for this Amazing short Documentary about the Photoelectric Effect!!! 👍😁

How simple is brilliance ! just a hand made tube and a couple of electrodes.. no computers, calculators, .. but as simple as discovery of fire... how stupidly simple must you be to be brilliant?!

Very well presented.

After Newton And wisstein, he madw new steep

Okay my comment 🎉

Replicating the Franck-Hertz Experiment was one of the experiments on the "menu" of my Senior Lab class. (As I remember, we had to pick 4 out of 10.)

Just subscribed, buddy you are good. Fantastic job on the video.

Another interesting story is the impact of the formula from Johann Jacob Balmer on Niels Bohr's atomic model. Balmer found it 1885 but it took until 1913 that someone (Bohr) could explain it's meaning.

They should continue to question themselves, and more severely than they can. This is a magneto-dielectric universe. Relativity and Quantum physics have been falsified, however clutching to tenure under the effect of the Asch Conformity Test guarantees a slow death to the paradigm staining academia. Studies are pouring in on the electric/magnetic nature of the universe. Standard cosmology is collapsing at an accelerating rate. Have you looked into the structured atom model (SAM)? Have you listened to Eric P. Dollard discuss his work? peace out

Very well explained. It would be interesting to see if anyone tried to replicate these early experiments but using modern instrumentation.

New great name: Frankenhertz

Take a billion people and average out the number of calories they eat each day and then declare it a discrete amount without ever looking at the individual calories they would eat. Yeah okay that sounds like the fraud called science.

Quantum physics grew out of control with the construction of multi billion dollar colliders that haven't resulted in humanity's lives better for example like oil, refrigeration, air planes, and automobiles. And no, lasers are not the result of quantum physics.

The brilliance, innovation, and tenacity of these men is staggering. And the summary video is succinct and insightful. Thanks for the great explanation!

Thanks for posting. Extraordinary what physicists achieved in the early 1900’s as quantum theory was being developed and tested…

Fantastic presentation and explanation. Thanks

Thanks.

Great research and presentation. Having taken an undergraduate degree in physics many, many years ago, I sit thinking how nice it would have been to have the internet and videos like this. Nice job.

Great video! This encourages me as I am doing my PhD research in engineering via experiments

The philosophy behind science, which makes it distinct from religion, is that no experiment ever "proves" a theory. Science progresses when theories are disproved, and the theory has to be modified, the best example being Newton's laws of motion which had to be modified for relativistic effects at high speeds.

Another lovely video, you reveal the humanity behind these great achievements.

What kind of sources do you use for these videos?

It's wonderful to cover this work.

Great video

❤schoolchildren and students to measure the Universe, dark energy, black holes, etc. two devices “laser tape measure with fixed fixation at 1,000,000 meters” and “Michelson-Morley HYBRID Gyroscope” you can make scientific discoveries; in astronomy, astrophysics, cosmology, higher theoretical physics,...

A comment 😂

Nice videos, I like'em!

Scientific micromentaries without fluff and filler like into sequences are awesome, keep it up dude!

Make a video on maxwell 4 equations

why do americvans say "ex-peer-ments" it is ex-per-ee-ment please learn to english :/

these videos are great, showcasing the men of high intellect who were able to articulate the secrets of the universe!

I did the experiment in a physics lab in college. Very interesting. We spent 9 hours taking data. We measured the speed of the drops for zero electric field. positive and negative. From that you can cancel out the drag of the drop going through the air. We got an excellent result. We also did E/M. great video.

0:30 - spellcheck might have corrected “defeleted” into “deflected”

"...mass to charge ratio..." I kept hearing *Master Charge* ratio (MasterCard until 1979).

Thank you.

I had read that among Fletcher's papers which you mentioned was a letter by Fletcher in which he stated that he, not Millikan suggested the use of oil drops rather than water. This would seem to make Fletcher a major contributor to the work rather than just a technician. The letter also discussed his conversation with Millikan in which Millikan said he, Fletcher, could be the sole author on another paper while Millikan was the sole author of the oil drop experiment.

There's really no need to show stupid stock video of two guys in lab coats to accompany the mention of "scientists" in the video. This kind of stuff really detracts from an otherwise very informative video. From now on, please assume we know exactly what a scientist looks like!

You can also make a video about Robert Mulliken and his contribution to chemistry (the concept of electronegativity) because both names: R. Mulliken and R. Millikan are easily confused - yet they both won the Nobel Prize except one was in physics (1923) and the other in chemistry (1966). I remember my confusion when studying the history of chemistry, knowing only about the 'oil drop guy' 🙂

2:04 Wow! Dr. Hess had a lot of students!

Love the details of the experiments. 99.9% of videos just state determined facts without at all discussing the experiments. A notable exception is maybe the double slit experiment

Have you considered making the music/ambience slightly louder in your videos? I know it's there but I can't hear it at all :')
