Dude, you saved my butt with this. Thank you.

[@okscience8599]

glad i could help!

[@kkat5568]

ok science, I got an A!!! :D

[@eliciagarcia3601]

You can also call the stimulus strength the "magnitude" and the perceived strength the "just noticeable difference" or "JDN".

[@aishusworld5151]

"JND" just noticeable difference 😀

[@marssaviour3469]

Was confused for almost 24hrs on this. You just saved me. Thank u bro

[@meghand8634]

Subscribed! Holy moly, this is totally going to be the channel I refer to for the entire quarter!

[@pix3l_brat]

Your take home point- The greater the stimulus is the greater the increase in stimulus required to detect change is actually Weber's Laww

[@jacobhernandez4347]

Thanks brother I’m reading his book now, I had an idea but you just made it clear as day, I just love how we can access information so quickly

[@jff711]

Well-done! Thanks for this clear and helpful explanation.

Thanks for this video man!! It's specific, easy to understand, and the examples are very good too.

[@liviasknittingpodcast]

I haven't even finished the video yet but damn that's a cool intro!!

[@Nav2001]

Simple ,easy to understand help alot

[@PhươngĐỗ-v4p]

Thanks so much for this useful explanation ❤❤

[@tongwing9320]

Great video explains very clear concept. Appreciated and respect bro!

[@hijamsalina1873]

Thank you so much, Sir. You explained it clearly and more easily than my professor. 😁

[@isabelavelasquez8820]

What a great video to finally understand this.

[@teamammcri2224]

Lucidly explained

[@prishitarathore1486]

Well explained!! You saved my life.
Why don’t you have enough subscribers though? I subscribed right away after watching the video.

[@uugh_3446]

you shouldve had added a final example for that very last math part... i still dont understand how to get the "k" of something and how exactly do u multiply that w the stimilus strength

[@theprop448]

Awesome explanation

[@MrDashima]

awesome info, nice visuals, and a clear voice.
The volume fluctuation, however, is very painful.

[@transportation-talk]

Thanks for your comment. I thought something was wrong at my end.

[@xiuqlucky7612]

What's the difference between Weber's law and fechners law

[@zahra7755]

why do all fechner's law vids have background music

[@deepanshikacharia9398]

Great video. Thanks a lot!

[@pix3l_brat]

As someone totally stressed by my upcoming exam, the fact your voice gets super quiet randomly is filling with me absolute rage and it's not your fault but jfc lol

[@karinac7181]

amazing! helped me so much, thank you!!!

[@sonaideb807]

Wonderful explanation love it

[@teamammcri2224]

Hey can u plz explain Steven Power law ?

[@funfair-bs7wf]

Nice video, but why does the sound behave so strangely (sorry my english isn't great)

[@sunidhirao4651]

Great video!! Thanks a lot!! ❤

[@ReigninAmazin17]

For simplicity's sake, I understand why at 7:10 you show the x-axis as "# of books". In actuality, shouldn't it be something expertly confusing like "the logarithm of the weight of the books"? What do you think.

[@okscience8599]

yeah, you're absolutely right! i tried to frame it as "your perception of the weight" instead of "# of books" to make it less confusing! :-)

[@harryhocus7367]

What's up with your Mic??

[@amritachaudhary9311]

You saved me dude.

[@tommysdaman]

Plugging decibels into fechner's law seems silly. Decibels are already logarithmic. S = kD seems like it should be fine for sound strength D in decibles.

[@inspirationelham2239]

great job , thank you !!!!

[@bottolfsensen]

Love it!

[@ivonnetv2399]

thanks you very much!!

[@mariazarzuela6602]

THANK YOU!!!

[@brtmax5174]

Thanks!

[@oliverandm]

8 sugars? 9 sugars? Came for insight, not advice on attracting diabetes. But great video!

[@qqqAvi]

what's your problem, dude? Triggered about anything? What the heck are you talking about.

[@aliciajourney]

thanks!

Story of my life

[@G.Giorgio]

on little correction - fechner is not pronounced with an k :p

[@penisbreath952]

please improve your production quality! animations are sloppy and jumpy, audio volume is super inconsistent and drops at times making it hard to follow. same thing with audio cuts, theyre a bit abrupt at times. look into compressors(audio, not gasses) and make sure to cut your clips with a bit more space before the transients and maybe add some fades!

[@ChiDraconis]

So basically if I go from 5 micro gram of #5 Rat Blaster to 5 Kilograms I get the same effect? You're wrong it gets me a ticket to the morgue where the ultimate high is 20° Below freezing!

[@chriss6439]

so basically newbie gains.. why is that theory important btw

[@jazzz8172]

Wow my ancestors made this 😂

[@user-gj3fi4xs1h]

fechner is not pronunced with K and weber is not pronounced with v
