I'm a 1st year student of Engineering in India, this was a very clear explaination of this topic, made me get a holistic view of everything about TEM. thank you very much :D

I'm a "lowly" software developer working on an information system for TEM users... and this was a really good introduction that's helped me start to understand what my users are "going on about"... thanks. Can I just make a suggestion though... if you put your picture of your face over on the left instead of the right, it'd cover up less of the slides????
Nicely done. Given the dearth of clear, accessible introductions on the subject, I would echo other commenters below to make follow-on videos on SEM, STEM, EBSD, etc. You're a wonderful expositor. Thank you. one very minor point: the slide "Results of D&G experiments" (circa 22:09) did not have labelled axes - which hindered my understanding of the results and your discussion points.
In the presentation, you mentioned that there is a course on Advanced microscopy. May you kindly advise on which site this is offered if it is online. I am very much interested in learning more.
Great video, thanks! But I do have a pet peeve: Abbe was German Scientist, you kinda butchered his name. The E in Abbe is really short, I do realise that there is no sutch thing in english which might make saying it correctly difficult.

Thank you Tonya for this amazing lecture. 🙂
Thank you so much for your far helpful video and neat explanation
I think I'm Inlove, lol. Great Lecture.
great course and pefect explanation
Excellent lecture. Thank you so much!
Amazing lecture!
Very helpful! Thanks a lot for this
Excelent explication!
Thank you for the clear explanation 🙂
above you wrote R is inversely proportional to NA but then you said the larger the NA, higher the resolution. Isnt it contradictory?

I think It's sort of polar axis,not so hard to understand,when I watched your comment I was afraid as there were some mistakes that blocks me.
Well done ! Thank you
Why do atoms look round in TEM images even though they have different orbital shapes?
I liked the content and the didactics. Could you add EBSD?
Many Thanks!!!!!!!
how do i find the average distance between each electron in the electron beam?

Hi. Sorry, this is for a course at my university, where I work. You would have to be a student there to enroll.
#Tonya Coffey Please Give me a PPT slide for Scanning electron microscope
what is your refrence
I have many, and they are generally cited on the slide, especially for the images.
Great video, thanks!
