Gastrotrichs: Four Day Old Grandmothers

[@Nanamowa]

When Hank said how the cilia on the Gastrotrich's head were sensitive to the motion of the slide, I suddenly remembered that the camera was not panning over the environment, but that the environment was moving according to the slide. It really reminds you how perspective changes everything.

[@anteconfig5391]

I didn't even think about that. I actually thought they managed to make the scope itself move

[@shashwatchamoli7221]

I don't understand Can u please explain

[@anteconfig5391]

@@shashwatchamoli7221 When you use a microscope you have to put the microorganisms or cells on a thing called a 'slide' and that slide gets put on the stage of the microscope. The lens is what you look through but you don't move the lens to look all over the slide, you move the stage or the slide. Check out this crazy lady kzbin.info/www/bejne/haTNoWaNbMiaipY

[@shashwatchamoli7221]

@@anteconfig5391 Actually i know about the basic usage(lens,slide)but what is confusing me is that we actually don't love the lens and won't moving the slide create some disturbances which will affect the movement of these sensitive microbes. Thank you for replying btw....

[@anteconfig5391]

@@shashwatchamoli7221 sorry, I mean to reply yesterday but I guess I forgot. Yea, you're right moving the slide would do that but at the same time we're talking microns of motion so the liquid they're in shouldn't move very much. I guess that's why those hairy grandmas can sense this motion. I think that if they managed to move the lens instead that the microorganism wouldn't be able to feel the motion.

I just wanna take a moment to appreciate Andrew huang's music Gels soooo good with the video❤️

[@dgde6788]

If ever you guys do a behind the scenes episode or the like, I’d love to hear more about the music. It’s pretty unique amongst these kind of “nature-y” videos what with the bass heavy tones

[@avariceseven9443]

Speaking of the music, if you're into anime, the music has similar vibe or effect of those used in Mushishi. This channel actually reminds me of that anime. In Mushishi they explore the world of usually unseen "things" that affects the human world. And those things looks like these microscopic life. Its kinda similar how Greek mythologies try to explain everyday things using anthropomorphic gods but in Mushishi the things that causes maladies and stuff are these microbe-like things that are usually invisible to normal human. To anyone interested, it's a relaxing anime that covers mature and a bit of dark content.

[@IanGrams]

It's made by a really cool artist named Andrew Huang if you want to check out his channel: kzbin.info But I agree it would be cool to hear him talk about making music for JttM.

[@hrdsht]

+1 Andrew huang listen to us! And make a video about the creative process that goes on to make such compelling music

[@flowersstorms8863]

Having a ruler next to the magnification level to indicate the size of a millimeter for example would be incredibly useful for understanding the size of these animals. 400x means nothing but 0.06-2mm is understandable.
