At first, I was like, if photon wavelength is the issue then why not just use smaller wavelengths? Like gamma rays for instance. Then I realized that gamma rays would just pass through the sample instead of being reflected, yielding no image. Well played, universe. Well played.
I believe that fact is essentially the definition of whether a frequency is disturbed by matter, isn't it? If a photon is "too small" for a molecular structure, it's because the structure disrupts the wave? If you throw a basketball at a cheese grater, the energy of the ball will continue predictably (ignoring the classical thermodynamics of mass (which photons don't have) which would push the grater). But if you throw a grain of sand at a cheese grater, it will interact with the complex angles of the metal of the grater and bounce off at God knows what angle. In the case of light, that varied diffusion disrupts (absorbs/reflects), absorption being the disintegration into thermal energy? I guess I'm not entirely sure why molecular structures interact with light at all. What is light reflection caused by if it isn't two masses colliding?
@@Goreuncle yes, actually gamma are not an example of wavelength that would pass through, but larger, non-ionizing wavelengths would. The point of ionization essentially being both the determining factor in both relevant limits: the destruction of molecules and the demarcation of visible light.
*Can anyone explain to me Why one of the best channel on science videos get so little attention when a beauty video gets millions of views* !!! *This channel Deserves more subs and Views*
I'm stunned that this video even exists. Secondly, I wonder where I was, where I've been, when this information was discovered? Thank you for making this video. Yeah...I subscribed. That's a given.
THIS WAS ABSOLUTELY MARVELOUS. I did not know we were in such a great development pathway! I kind of live as if the past is more interesting than this future/present, but I’m wrong! Your explanation is so crystal clear too, thanks for the content!
Great video again, Jon! Just one remark to pay homage to peer-review: Animalcule means "little animal", from Latin animal + the diminutive suffix -culum.
Outstanding video production and editing of storyline. The facts presented were interesting, engaging and educational. Your narration is superb! Well done.
You stated clearly what I've been taught in school in a very short time. Thank you I'm out of school now but I still like learning about what makes the world go round that's why I search RU-vid and the net as well as PBS programs to learn more. Thanks for your video series
Wow Truley amazing the ultra 4K HD 200% vision Inspection. i Think you should mention teh famous video game among us in your next video please and thank you
Cool video. One critique, At 4:52 you mention that the photon's wavelength is bigger than a virus, but also that a photon itself is bigger than a virus. The latter is not true and I feel might cause some confusion.
This video should have a better title. I wouldn't normally have clicked on this as I know how (at least early microscopes, as well as SEM, TEMs) work, but thought it would be fun to watch. Was I ever surprised when it got into the details of the most amazing modern microscopes that now exist or are under development. Compressing photons? Amazing.
Anthonie van Leeuwenhoek was Dutch. He was a good friend of the painter Vermeer. (Girl with a Pearl Earring). I wonder why he sent those letters to England.
Thank you I know 😢 it's been three years u posted this but 😢 I would love to see same reference for an assignment in the future thank you 😊 sir great job
We really do owe to all the inventors, scientist, doctors, and patients that helped develop technology and treatments for virus and bacteria that have plagued mankind.
The part comparing the photon's wavelength to an atom shows a yellow sphere labeled "photon" which visually implies that the photon itself is larger than a virus
The determination and creativity of human minds, combined with the endless efficiency of computers and information holding devices, can and will make our species a powerhouse of the galaxy, if we're not already.
Yeah. This could have been explained in a better way. Visible light photons (200 nm max resolution) can't illuminate viruses (100nm size). If you reduce the wavelength by choosing uv ray wavelength photon or x-ray wavelength photon, the high energy of this photon will fry the organic sample. Electron microscopes have resolution up to 0.02 nanometers. (source - www.reddit.com/r/askscience/comments/ryy07/what_is_the_smallest_object_we_can_identify/c49rw44/)
Ehrm, sorry for the nitpick, but it's kinda my thing... "-cule" is derived from a Latin diminutive suffix. So "animalcule" actually means "little animal". You can see it in "calculus" = little pebble (as used on an abacus), and "molecule" = "moles" + "-cule" or "little mass". Other than that, I really like these "ocean of photons" visualizations! It's the kind of thing I know must happen, but seeing it in action really lets me grok it.
Thank you to all great minds throughout our history for inventing these microscopes. I can't imagine how they're able to come up with new things from scratch. Minus the modern technologies to boot!!
4:58 you said "photons are far larger than atoms" when thats not true if im not mistaken. I think you should change that to "The wave length of photons are far larger than atoms". Otherwise your confusing people as youve done to me. Please do correct me if im wrong.
No, he says "wavelength of a photon of visible light" immediately before and after that sentence. 4:50 Some photons are bigger some are smaller, but he is clearly talking about visible wavelengths, which are all too large.
@@onetwothree4148 Several times it's denoted that photos have size or diameter which they don't. Or course we know the connotation is the wavelength, not size.
@@onetwothree4148 The image also suggests that a photon is larger than even a virus, it makes me think that maybe he didnt do it by mistake. Which is also why id like him to provide some explanation. Either correct me or correct himself but im sure hes probably refering to the wave length not the size of the photon. Photons have less mass than even an electron and atoms have at least 1 electron.
@@jevonmcpherson8054 the explanation is way more confusing and complicated if you draw a photon as a wave instead of a particle. He mentioned multiple times that he was talking about the size of the wavelength, and he did preface the explanation as not being entirely literal. Describing a visible photon as a massless entity that interacts with matter as though it has a specific spatial size is basically true and a very useful heuristic
Jevon, when creating this video we went back and forth on how to model light. In the spirit of George Box, we finally decided the large particle model was most useful in this context. We have a note on screen explaining this when we first introduce the "photon as a particle" model. I understand your critique about bouncing back between wavelength and size but once I established with the viewer that we're going with a particle model in this context, I felt it was fine to talk about photons as having size. The times I mention its "wavelength" are really just nods to the people who I knew would be upset with the particle model. Maybe what I thought was a nod, just ended up making it worse. In the future, I'd like to do a series on light: how it has been modeled over time, what we currently think it is, and so on. This animation wasn't the place for all of that.
Great stuff, John. This will be a welcome addition to my "roster" of played videos for my Biology class next fall (hopefully). Might I suggest you expand on this idea to demonstrate how the invention of the microscope led to the discovery of the Cell Theory? That's a direct standard in my home state of Florida, and I suspect it is in other states as well. There's a couple other cell theory videos out there, but, well...you can do better. Fingers crossed! Thanks again.
Have you seen our animation on major evolutionary transitions? That one might work for you. www.statedclearly.com/videos/what-caused-lifes-major-evolutionary-transitions/
It said ' microscopes the things that let us see viruses ' bit I understand the only one that can see viruses is electron microscope and then it's only dead virus. Raymond Rife was the only one with ' light ' microscope that could zoom in on live viruses.
It was Nicolaas Hartsoeker who researched sperm first. Not antonio van leeuwenhoek. he just went with it and claimed that he was the first one. But originally it was Nicolaas hartsoeker who discovered it first.
Absolutely fascinating. Had you thought that for millions and billions of years your atoms, those that form your body today, will remain in the universe after you die? You won’t even have the ones you have today in 10 years, they will be out in the universe in such short time even if you remain alive. It’s like the Adams that make you are only going through you.
In the same way that a method of shrinking photons was found to complete a certain task, humans will find a way to direct and produce shapes and configurations of the quantum fields that do not happen normally under natural circumstances. Like a set of tools and techniques based off of the way the fields make "particles" exist.
When you say that photons are bigger than atoms or even viruses you are only refering to the wavelength of visible light right ? Great video keep up ! so much info compressed in 10min video
