Hey guys,
While I recommend that people watch the new version of this video and not the old one, there's one good reason why you should check out the old version also:
In the new version, I calibrated the microscope for 10X and 60X objectives.
In the old version, I calibrated for the 10X and *40X* objectives.
So if you want some extra practice, I recommend you try and figure out the 40X calculations on your own and then check out the old version of the video.
Thank you all for your very kind comments,
I'm happy most of you have found this tutorial helpful.
Oh my god, thank you so much. You just dragged me out of hell.
Did I just drag you out of college? :D
Lol, we'll just wait and see man.
this changed my life
+Salima Naj Seriously?!
why can't we have educators like this in our educational system?amazing!
Because the education system is not about helping learners.
It's about getting approved for payments from the government.
They have no need for people like me.
got my a level practical tomorrow. the teacher is a shit so you just saved my life sir thank you
+xingmi I have mine tomorrow too! Good luck!
+xingmi You're very welcome.
+xingmi Good thing to know that I'm not the only one cramming lol :) good luck!
+xingmi My practical is in an hour, so glad I'm not going through this alone ahahah
+ByronClips My exam was great! thanks again :)
It was not just informing but also relaxing to watch his video. I loved how the simple the video was but at the same time teaching all of the essentials without making it seem too complicated. Also, props to the wonderful music at the beginning and end of the video.
You're welcome :)
I've spent about 2 ro 3 hours of revision trying to understand how to calibrate using an eyepiece graticule and this video is the one that made me understand, thank you
You have no idea how frustrating I was finding this topic because my textbook doesn't explain anything whatsoever. Thank you SO much. I finally get it!
super clear!! I'll show it to my students
Thank u so much sir u saved my life my lab teacher doesn’t teach us anything she just expects us to know everything and it’s bio 1 !so I always feel so stupid when she tells us to start lab but after watching ur video u gave me understanding thank you god bless u
Really uderstood each an every concept from this video......sir .. The new version of the video is great ! Just loved it ! Thank you very much for this.
i currently have a lab zoology course and i couldn't understand this specific topic. our prof even sent us a yt vid and i was still having a hard time and was totally unsure of my answers. but your video helped me so quickly right now, so thank you so much!!! i'm your new subscriber
Thank you! My biology AS practical is today - please wish me luck!! This was very helpful
a god forsaken parasite lab that took 2 hours for the instructor to explain this , you just did it in 10:53min ...thank you.
Glad it helped :)
Thank you so much. It will help me for my upcoming practical examinations
if only my teacher could explain like this then I probably didn't had to get grades like D in my lab
Thank you so much for this
Most "teachers" need to learn how to teach! Not the material they have to get into student's minds, but HOW to get it from Instructor to student's brain. Schools never seem to evaluate teaching skills only material knowledge, Such a waste of talent.
Wow finally it makes sense to me. Thanks Ron you are a star
Fantastic! Far better explanation than I have received in the past.
Thank you so much. For real you won't believe my struggle before this video came.
Thank you so much My daughter got it like! Her practical exam went very well because of you so thanks a lot!
Thank you sure soo much for the tutorial, i was searching for this all over the net. Thanks a LOT!
aaaaa thank u so much. i wasn't getting it in our class for some reason but u totally nailed what i was confused about!
Very helpful
I was confused since last year
Today my concept of micrometry is damned clear sir
☺️
Truly phenomenal sir, very articulate, clear and crisp explanation. Thank you for sharing this amazing with video.
Excellent. Easy to understand. Layman wordage rather than Tech-speak. Thanks
Brilliant explanation, followed it perfectly from start to finish. You rock!
I'm more confident in my microbiology class after this, thank you so much!!!!
Great dude...I had watched old version of this video...but this was fantastic n much much improved.In lockdown without mah teacher i can easily understand..Appreciated!!
Very helpful video- explained thoroughly and clearly, thank you!
You just saved my life; and made me wonder what was so hard about this? xD
Thanks!
I have a practical exam tomorrow ..this helped me alot
Nice presentation
Good English, content now am so good in practicals
Info was very well put. Thank you!
Thank you so much! This is the best instruction Video I've ever seen!
Excellent job and thanks for your help
you. saved. me. and. my. lab. group. THANK YOU SO MUCH
Very nice! Thanks for helping me get my head around this :).
Very clearly explained brilliant communication skills!
Thank you so much!!!
That was a really good tutorial I understood it very well!
Thank you! I wish I had watched this video before doing the lab.. I screwed up on the calculations and got a really bad grade :c
+Haru Saeng Got mine tomorrow....TH-cam is one of the greatest inventions of all time!
Great explanation! Thank you!
Amazing video, thanks Byron!
Thank you, sir. Great teaching.
Thank you for making this tutorial!
Thank you so much...your presentation was so clear.
Thank you so much, very clear n brilliantly explained
very clear explanation, thank you :)
Thank you! will help me in my assignment very much
U sir are a legend 😭😭❤️ bless ur soul
Definitely better than the other tutorial, Thanks :)
Question: once I've found the value of an ocular unit at one magnification, can't I calculate its value at other magnifications rather than recalibration? For example, if I know the value of one ocular unit at 40x magnification, couldn't I divide that by 4 to get its value at 10x?
Thank you man. Absolutely great
PERFECT!!! Thank you VERY much!!!
Very Very nicely explained
Great tutorial, just one question: what would you do if the stage micrometer had a 0.01mm scale but the ocular micrometer had a 1mm scale?
thank you, now i am ready for lab exam
Thanks! This is really helpful.
Excellent explanation, but could you turn up the volume? , i had some problems for listening. greetings from mexico
That all helped me very much! Thank you sir!
Wow...best description...thank u.
wonderful tutorial!
Like1.7+ Super clear and concise! Awesome video🙌🏾
Okay but why do we need to do this? Is it because the eye piece loses accuracy the more its used?
Also it would’ve been much more helpful if you showed the conversion math.
Thanks, that was super clear!
This was very helpful. Thanks!
Helped me a ton!!! Thank you verryyy much!!!
Thank you so much sir!
Excellent
absolutely amazing video thank you so much !!
It was helpful video for me, but there still some questions:
1. In another video about this topic, she calculated 1ou = 96micron (with 40x objective). In this video 99micron. So are eyepiece graticules not standard.
2. If 1ou is 96 micron, can I use the same measure anytime for any objects with any microscope (with 40x objective)?
Thanks. If answer this question, I will be completely informed.
Thank you!very helpful.
Plz calibrate 0.01mm stage micrometer and width of protozoan euglena
Excuse me. Can you add subtitle for this video? This video is really nice. But, English is not my fist language. Thank you.
thank you sooooooooooo much..!! for this amazing video...
Thankyou very much, helped me alot
👍👍👍👍 in easy way, clear concept
LOL I'm watching this for my lab @ York! Nice co-incidence
awesome tutorial. Thanks
why to calibrate ocular micrometer if we have a stage micrometer?
Thanks! that's really helpful!
really helpful,thanks
Thank you!
This is all great if you have a eye piece with built in calibration. I only have the slide for the stage. I am trying to figure out how to calibrate the camera to the slide. It appears that the camera from Am scope is about 20x to begin with. So, wouldn't that make the 10x actually 200x? Can't seem to get a straight answer from the sources I have tried to ask.
OMG THANK YOU DUDE!!!! My teacher literally cant explain this right.Xd
Thank you soooooooo......much
very useful thanks
What about if we dont have an ocular micrometer but only a stage micrometer? I have just got a camera with a logiciel so i guess i dont need the ocular micrometer ?
Nice dude, god bless you❤😍
i love this video thanks
Thank you,
thank you i love it
well explained 👏🏼👏🏼
can you tell me how can i do it by magnifying glass X3 and Microscope X 4
Thanks so much. A question please, what does they do not made the eyepiece size equal to 1 mm? of sure there is a reason, seems to me.
Thank you
Thanks a lot sir
Thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
you just saved my day!!!
thank you
Really helpful! Thanks a lot :)
