you are an amazing lecturer. I can easily visualize what you explain. its like you kinda drawing it in my mind. it is hard to understand this hard topic in my college via zoom. this is a lifesaver for everyone who is interested in science. Thanks a million from MSc Student in Italy
24:50 The life span of Henry Moseley sparked my interest so I went to search and read about him. A great physicist who got killed during World War I at the age of 27. Who knows what other contributions he might have added to the field if he made it through; may your soul rest in peace sir. This is very tragic, what a loss!
Sir I have a doubt. You told selection rule for FCC .But for the example crystal, it could be Simple cubic also. How can you be so sure that it is FCC. ??
Hi Arjun. If the crystal is SC, you should observe the peaks that make (h2 + k2 + l2) ratio look like 1,2,3,4...(Note all of them). However, the series is 3,4,8... . As for BCC, it is 2,4,6,8.., while for FCC it is 3,4,8,11... . Hence, the XRD pattern is more likely from a FCC crystal.
These lectures belong into the absolute gold of the content that's available on TH-cam. You are lovely, MITOCW and Prof. Jeffrey.

I can hear this guy all day !! What an amazing lecturer !
As a PhD student student studying zinc alkaline batteries this series has been amazing
Same here
Excellent lectures, lot of thanks to MIT for sharing these materials.

Very impressive teaching style. Difficult topics made easy in a very simple way.
As a materials lab tech, this helps a lot for a better understanding of my analysis
Lol, I wish the German professors at the Heidelberg Uni were so passionate about XRD. This lecture is amazing. Thanks a lot.
Yeah.... Lol
Btw this guy is pretty good at teaching. Look how he is dancing and teaching.
Great lectures. It helps me understand XRD and Braggs law
Thank you for sharing this knowledge with us.
And I hope the coughing person at the end is alright.
Now I am clear thank you. ❣️
You are a great teacher!
Excelente aula!
I'll be honest it's all a little above me right now putting it all together just means more practice.

Great lecture! thank you
Good lecture!!
why multiply by 3
Brilliant
👍👍👍👍👍
