@JohnRennie hi
sir first of all your picture looks stunning.
 
Hi :-)
I'm about to start watching an online lecture on general relativity so I won't be able to chat for an hour or so.
 
is there any link?
 
This one if you're interested
 
sir I had some question related to electromagnetism but we can chat later on thanks for the link sir.
