The Gadget That Changed How We See The World | Cell | BBC Earth Science 

Oh the sweet irony of a video about something to enhance our vision being uploaded in 480p in 2024 🤣

1:40 I bet a lot of people had the curiosity. But only that one guy had the money and the technology...And the curiosity.

I like at 2:29 our lens maker is not only looking at a lens, but through two other lenses at the same time

Dang, didn’t know Leeuwenhoek made the first microscope. We study him as a scientist, but he was also a master craftsman.

- I've looked down a fair a few microscopes before... - Yeah, look through the other side. Like, the lens must be between your eye and an object, like in the other microscopes you said you've used.

To talk about an astonishing, ancient microscope and only show a few seconds of footage from it is rather annoying.

Watching this video in 8K resolution is the best part. Thank you BBC for uploading it with high resolution

As a child, I was given a set of science encyclopaedias from which I learned about Leeuwenhoek and his "little beasties" from this time on, I was fascinated by optics. Now, more than 60 years later, I am still fascinated. I made a career out of it and have my own work room with high and low power microscopes and cameras adapted for high magnification. It's a very absorbing hobby in my retirement!!

"just in case I need help. what do I do?" "well it is on... the wrong side"

With his craftmanship, it's safe to say that Mr. Locke is very Hans on😅

You can achieve a similar effect just by crying. When you stop crying do not wipe your eyelashes. Let the small balls of tears hanging on. Now try to center your eye to the small drops in your eyelashes (it takes some practice). If you approach an object at the correct distance you will see your tears make an excellent microscope. Unfortunately the effect lasts only a few seconds. If you wonder why to use tears and not plain water it is because tears lasts longer. If you suffer from short live tears (a condition also called dry eyes) you may not achieve the effect.

His incredible craftsmanship and curiosity opened up new frontiers in science and medicine. 🔬

I'm sure this microscope would've been amazing for scientific field work in it's time. Such an elegant solution!

what's incredible is they got that through a camera lens

Gem cutting techniques, cabochon, encased between two plates, the correct crystalline structure. with a control screw to replicate the hand moving it to-and-fro, but with more control...

Very interesting and a genius invention, but fiendishly difficult to use? All Hans said was turn it the right way, move close to the eye and use the focus wheel. The instructions have not changed in 300 years. 😀

Thanks for presenting this. I always saw illustrations of this microscope, but they never described how to use it!

Hats off to such artisan and of course Thank U BBC. 👍

“Oh wow” - that sums up the video !!!

I can' believe you young whippersnappers think this footage is "bad quality".

(See's thumbnail).. Ah yes, the needle in the eye... That could certainly change things.

I had a biology teacher in 9th grade take us out to collect water from a pond and bring it back and view it under a microscope after I saw what was in it I never went back in that pond ever again!

And so, the man who told everyone that their curse was caused by tiny, invisible creatures, went from lunatic to genius.

in some certain way, when squinting with one eye closed to a light source not directly pointed towards you, you might be able to see granules of floating round stuff, you can see them move and even observe it more when you slightly twitch your eye

🎶 There must be something in the water 🎶

Magnifiing 500 times?! 😳 I want such a lens!

Thank you for the video

"I see green...red roses, too...."

I cant get enough of stuff like this

reminds me of the ball cap inside a ink cartridge for modern fountain pens. I used to cut the plastic cartridges and collect the ball inside each of them (kids thing, you know). This ball are very tiny and clean. One day out of curiosity I took one ball very close my eyes and saw through it, I saw transparent shapes moving and some small bunch of round transparent things, This were the micro organisms. I could say this because I had observed many things and organisms from microscope in science lap periods at my school at that time.

Why you guys upload videos at 480p😒😒😒?

"until Van Leeuwenhoek, obody had the curiosity to find out..." I'd argue there was likely plenty of people with enough curiosity, he was just the first person with both the curiosity AND the tools needed to act on it.

It's not that nobody had the curiosity to ask what was in the water before him... but they didn't have a microscope!

I find it amazing that someone one day thought I KNOW! LETS MAKE A MICROSCOPE by polishing a piece of glass and fitting it onto a brass plate HOW?

Born to explain science to the public! ❤

These aren’t long enough. Where are the full episodes?

I knew about this microscope already because the protagonist of Parallel World Pharmacy made a replica of it using his knowledge of his past life as a modern-day pharmacologist and uses it to explain how his medicine cured the Empress of her tuberculosis.

2:30 looking through a magnifying glass to make magnifying glass.

I think that microscope would work well for me, since I see very well up close.

This video was WAY too short. Thanx4sharing thanx4caring ❤

Wow that was the first time that I have seen or heard of that. Cool!

😊🙏 Marvelous insight into the discovery & making of our first microscope! Jolly excellent little presentation indeed! Thank You So Much BBC Science! 🌷🌿🌍✌💜🕊

Very clearly visible in 480p 🥸

"I've looked down a fair amount of microscopes in my time." "Oh wow, I can see things moving!"

Ohh Come on man! It's 2024. 480p really?!

The Dutch invented these first microscopes were actually invented to inspect the fine quality of cloth weave. Then they started to observe other things like human and dog spermatizoa.

Since 1985 we know how Leeuwenhoek did it: no lens-grinding. All his lenses were melted droplets, perfect spheres, but then mounted against a tiny hole drilled in brass foil, to eliminate most spherical aberration. The myth about "lens grinding" let him keep his secret safe for centuries. Poor Robert Hooke had to actually grind his tiny microscope objectives, and then never duplicated leeuuwenhoek's 2000X instrument. Also, these devices were not crude. "Modern" microscopes let you move your face away from the sample being viewed, so various illumination schemes can then be used. Leeuwonhoek's version had to be held in a sunbeam. But it was a century-long myth that "single lens" instruments were inferior to professional scopes. No, and it took centuries before professional scopes approached the quality and magnifying power of Leeuwonhoek's best devices.

I would love to get my hands on one of these! :)

Honestly awesome

bro changed the whole timeline

I made it using torch bulb lenses 40 years ago.

I remember the popular book "The Microbe Hunters" by Paul De Kruif tells the story of Leeuwenhoek in the first chapter, very exciting.

The Mullaperiyar dam in Kerala, over 120 years old, is in critical condition and threatens millions of lives. Monsoon season is upon us, when the dam reaches capacity, and this year's rains could be disastrous. We need to get it addressed! Please consider creating a special program highlighting the urgency of addressing this dam's safety concerns. Let's work together to prevent a catastrophe. #SaveMullaperiyar #KeralaDamSafety

BBC why are you posting videos at 480P resolution??? 🤦🏻‍♂

Animalcules. I love the way described these newly visible things. Critics said that the lense distorts what they see so why should they trust anything that is said to be seen? Others said that God did not intend for us to see it because He did not create an eye that could see the microbes. It was His secret world for Him to know and for us to "butt out" of. The things they said is very entertaining to read.

Interesting but much too short and only 480p...?!

Where am i looking At the wrong side 😆

Is very similar to the modern Folscope !

At 4:08-12, you can see through the lens.

My dumbass thought all of a sudden Anton Van Leeuwenhoek was 3:03 this guy for a second 😂

WOW----------it gave birth to the entire field of microbiology the study of tiny living things-WOW

Aah yes, the exquisite water from the middle of the lake. Not like the cheap stuff on the shore.

leeuwen hoek found the amoeba with a primitive microscope

Even a Cellphone camera lens can do this too

microscopes are great but what is this dude using for paddles, two square sticks???

Wow Amazing! Never knew about that!

Video still rendering.

Transcription 1:59 is wrong. The name isn't Loncar.

The term "microscope" is a little exaggerated. Leeuwenhoek and other Dutch scientists were able to fall back on a tried and tested technique that was vital for the cloth merchant nation in its daily trade with textiles: the "thread magnifying glass" was used by cloth merchants for the microscopic assessment of textile quality and fibre composition. Not all of these optical devices had a glass lens. Drops of boiled or distilled water had similar optical properties. These were the poor man's thread magnifiers. If you like, you can easily recreate something like this with today's household resources: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-cnKCbW75dIk.html

Cool and yes, incredible.

Similar words l am sure That's amazing

I THINK, WITH THIS LENS, YOU CAN SEE ALL MADA FACCA IN THE UNIVERSE

Fascinating. 😊

Imagine seeing that for the first time...

Can we trust anything BBC after October 7th!!!! 🥜

Did they have magnifying glasses at the time? Was this just taking that process and pushing it to an extreme?

Uploader: You omitted mentioning Hans Loncke in the description and his name is barely mentioned in this video. I firmly believe this is a mistake which could be remedied. I will come back in a week to check my beliefs (You'd better remedy that mistake)

BBC (any flavors) can ONLY trigger RED THUMBS

yt doesn't support 576 and downscale it to 480 destroying image quality with low bitrate please render to 720p50 at least

The Dutch have cornered lenses from leeuwenhoek to asml :-)

Omg,that is so amazing!

Much pixel, Many wow

How does the focusing wheel work?

That is so cool.

Magnificent 👌

thats the story of cell bro i studied it and next exam is science after my language known as tamil

So the company Levenhuk is named after him or was founded by him?

Great vid

Water companies put sewage in the water

I thought Lewwenhook makes hooks

What POTATO was this video recorded with?

Excellent !! This document should be mandatory in French schools... were children learn that the microscopic World was discovered by Louis Pasteur in 19th century. What is obviously false, he even did not discover the vaccines or antibiotics he is credited for... he was at first a very good lab manager and lobbyist.

The only innovators BBC is left to explore are and long gone. Now the country is a shell of its past like an old man remembering his good ol days. UK has become a quaint anachronism.

1998 called. They want their resolution back.

480p resolution - oh is it the 80's again. Come on BBC you stingy network goons

I'm not sure if I want to learn what little... creatures moved on that !

Birth of the Door hole.

You'd think he would have written his techniques and processes for manufacture of the microscopes down for his family and children, or at least trained them to carry on after he died...nope, his knowledge died with him. Shame.

Ведущий выглядит как в криминальном кино про антиквариат 😁

They reupload the video guys 🤣
