- Опубликовано: 9 июн 2024
- Viruses are so small, they can't be seen with a normal optical microscope, so how do we know what they actually look like? Here we will explore the history microscopy to learn about the invention that let us see viruses, and beyond!

Correction: The word Animalcule is a combination of "animal" and the diminutive suffix -culum. The word molecule is built from the same suffix.
I just feel like I've watched 30 days of Science Lectures in 10 minutes
Doesn't it feel good?
would feel good only when you see in reality, but this is photoshop
Yes. I really enjoyed this!
3 years of me being in College not getting why Light Microscopes couldn't help us see Viruses and now...THANK YOU !
I think it’s insane how a channel this small can have this good quality! Great videos as always!
“Here we see the new guy in town”
This one killed me with laughter 🤣🤣🤣🤣
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?
Wouldn't gamma rays destroy the sample? I mean, I don't think DNA reacts well to them.
@@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.
We did discover what DNA was shaped like with x-rays didn't we? of course it was just a diffraction pattern but yeah.
*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*
This video is beauty too
That's how it goes.. trash gets to the top
And they so nicely explain things and don't talk down to us as if we were stupid for not knowing something ! I agree.
Because the average person is a moron and the social media in general is a gushing celebration of mediocrity.
Hans lipershey??
The part on chemiscopes from 7:13 on is absolutely incredible!
As a med student I'm excited to witness the future use of this technology.
You’re a great artist man!
love that soft little "woosh" transition sound...
The things that only cats notice... 😸
You really do explain complex matters clearly. Thanks!
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 RUclips and the net as well as PBS programs to learn more. Thanks for your video series
I hope this video goes *viral*
I'll see myself out
Don't hope , act , share , everywhere
This is a very fine way to inform over the RUclips. Thank you, B Koller
69 likes keep it like thattttttttttttttttttttttt
Lol!

Outstanding video production and editing of storyline. The facts presented were interesting, engaging and educational. Your narration is superb! Well done.
Such a beutiful, clear explanation about microscopes in general. So interesting and engaging!!
You are helping everybody!! I love this channel

Could you imagine being the first to discover animalcules... I would be horrified for the rest of my life
but u will be oof
Especially if you realized that everything was coated in animalcules.
You dream about cat or dog... But you already have some friends since you born :D
An absolute gem of a resource for easily digested scientific information Thank you.
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!
"A Brief History of Microscopes" would have been a more appropriate title.
Fantastic explaining a very difficult subject to the simplest. Thanks for the video.
Great video again, Jon!
Just one remark to pay homage to peer-review: Animalcule means "little animal", from Latin animal + the diminutive suffix -culum.
Thanks, I added a correction in the video description.
Your videos are such a treat! I hope this channel gets to a million subs!
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.
Excellent...as always!! Thank you.
Amazing video! Thank you and please keep doing these fantastic videos!
Well made! Thank you!
Yay another stated clearly video, there is so much good info in this wowee
Absolutely clear! Brilliant video.
you came back with the animations, i love it!!! cry
Excellent video, as always!
Thank you very much, your videos are fascinating and really help
Those folks in the back room are pretty smart! Thanks for sharing the video and best of luck!
The more I come across your videos by chance, the more I think you are one of the best science popularization channels. Period.
1:20 Imagine the fact that he had to do to actually come up with this drawing. omg
I think this was a great representation of the evolution of microscopes, and for that I thank you!
that eye diagram gave me such a clear understanding of how they work. Thank you sir!
Thanks for this information
lovely animations, man. great job
great work Jon!!
It's been a long time! Great video
SO AWESOME...THANK YOU!!!
This is such an underrated channel. I am gonna do a thing.
Finally a stated clearly video :)
Rushing off to read all about chemiscopes. :) Thanks for posting
You have an amazing way of presentation dude....
Thank you so much for such a nice video. before watching this i have not known about scanning probe microscope
Wow... amazing well explained
Wow, despite being still in a pandemic and stated clearly having 400k subscribers, this high-quality video is still highly underrated.
what an amazing watch!
3:34
I especially liked the laser sound effect with the candle.
As a Chemist, this is now my most favorite video.
Wow I love your presentation I love science you make it even more exciting thank you
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.
Cracking video mate
Thank you Stated Clearly!
big help bro gave me smtn to use to start a project of the microscope
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!!
Amazing video man :)
It is interesting to our study of different types of virus in primary 2
Brilliant video to say the least
This video is amazing
Great video continue
Hi
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
This video *flu* over my head...
hehehehe
Lol!
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.
Thank you
That is amazing
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.
I've liked quite a number of your videos so I decided I need to subscribe!
More videos, more frequent!!
Because of you and you're series how many scientist are going to be developed my generation it was mr. wizard great job fantastic job
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/
Well my mind is blown... Or maybe that sensation was my brain getting a new wrinkle? Either way, great video (and excellent channel!)
10:22 it is just wrong to say photons are larger than atoms protein or viruses
The wavelength of visible light is larger
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.

thanks ur right, photons r sub-atomic.
time stamp is 5:00 though
Best channel on RUclips▶️▶️▶️▶️
At last ! Thanks !!
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.
Nice animation and explanation.
Please make a video about quantum physics . Please Try to tell in detail
How does this not have more views?!
Please comment about chemiscope illumination wavelength selection for specific imaging requirements.
Bravo
Great as used to be
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.
Owesme Lecture . . .
7:33 My brain just turned into soup
mind blown.
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
Make more!!
i recently saw this at school and i cannot stop laughing at 1:57 , it caught me so off guard 😭
you guys are literally saving and helping me soo much. If your a science major in college, YOU NEED TO SUBSCRIBE TO THEM NOW!!!
6:08 didnt know Roger Federer was into microscopes
Perfect, I think my Biology assignment is complete
I'd never heard of a chemiscope before; that's so cool!
your videos have fullfillness
From Robert hookes 7th generation great granddaughter you're welcome 😊
This new types of microscopes are fucking awesome
Animalcules is fuckin fantastic terminology! Should have kept it!
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
Yes wavelength
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.
Ahhh you picked that nit before I could : )
Thanks, I added a correction in the video description.
great
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.
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.
