now i finally understand why we (undergrads) aren't allowed to use the TEM.

imagine you have to see this sort of patterns... @_@'''

and this too........

HELL LOT OF PROCEDURES, RULES and TROUBLE.

you cant touch the tip of the sample holder, sample must be thin enough, aperture must not be contaminated, vacuum must be high, etc etc etc.

even the theory part is so taxing!

ohmy.

if something else comes out for exams (other than diffraction points), I am so going to 摧心肝.

someone save me please!
