all the mistakes one life could take

today in chem:


1. "now, what is goin' on here is a very interestin' phenomenon where...

...

...well... i dunno, y'all can look it up on wikipedia.com. they've gotta...uh... good description 'bout it."

2. "so what's happenin' in this reaction, it's like hikin'. say ya start from here 'n take this path 'n yer friend starts at the same place 'n goes this way instead. now...um. well. er. *insert frustrated noise and 5 sec pause* man, ah had it all planned 'n figured out nicely before...

...well. whatever. ANYWAYS these two reactions added together equals the final 'un."


and last but far from least 3. (my favorite)

(writes on board while talking) "so deltaH of fusion is when the state function is goin' from a solid to a liquid. so. it equals [H of liq] - [H of solid].

now what 'bout deltaH of melting? that's when it's goin' from a liquid to a solid. so. it equals [H of solid] - [H of liq]."

(wave of confusion passes over previouslycomotose class)

"so-"[student interrupts]

student: isn't melting from a solid to a liquid?

"...[stares dumbly for a sec]...wai- um. could ya say that again?"

(student repeats)

"...[turns and stares at board for a few sec]...um...[seems more confused]...oh. wait. yes. [corrects board for H of melting]...

so-i'm sorry-the deltaH of fusion is for liquid ta solid [starts correcting board again]"

(second wave of confusion in audience)

student: isn't fusion and melting the same thing?

"... ... ...um. ye-es. yuh. it is. [recorrects halfway corrected writing on board. then stares at board]

...so um. the change from liquid ta solid would be...actually ah don't think there's a word fer it..."

several (v annoyed)students: wouldn't it just be FREEZING?!!

"...ah yes! yuh. so it'd be. deltaH of freezing [returns to board]."

(much suppressed laughter from class)



it's even better when you can hear his southern accent.

yups.
i wanted to cry.
