I *got* nothing better to do.

Q: What will happen to electrons, with kinetic energy of a few hundred eVs, when they are incident onto a carbon film?

The answer was *obvious*, but came with a weird phrasing. It's some MCQ by the way.

A: They see the carbon lattice like a diffraction grating and get diffracted.

OK THAT WASN'T SOME APRIL FOOL'S JOKE. Apparently, electrons now get the 5 senses animals have and are capable of making choices too. They can choose NOT to see the diffraction grating and not get diffracted. This would not be a problem had the other choices been weird too, but nope, they happen to be comparatively more normal. I didn't highlight/bold/italicized the word *comparatively* because you did see it right? RIGHT?

i) They will get *repel* back towards *its* initial direction of approach.
-This option gives you the idea that the question setter has uber grammar phail, but I can't complain because I know my grammar gets more epic by the day.

ii) They will knock out the electrons from the lowest shell and as a result, x-rays *is* being produced.
- At least you know that the same question setter bothered to finish the question. Wait, was he/she the same person who vetted the paper too? VERY unfortunately, I didn't find any logic phail with this option at first sight. Electrons are actually capable of knocking themselves out - being at two places at any one time! Maybe it's because of Heisenberg's Uncertainty Principle oO

iii) Most of them will pass straight through as there *are* alot of empty *space* in the carbon film.
Uh huh. *WO MING BAI!*

So the options didn't make sense. *Np*, since the examiner decided to be consistent all the way in explaining the correct answer.


Almost impossible to get *repel* back towards *its* initial direction.
Not enough energy to knock out electrons from the lowest shell.
*It* will pass through, but *most of them* will not *pass through straight*. They will get diffracted as the wavelength is about that of the lattice spacing.

WIN



Ok so everyone's grammar is getting lousier by the day, *heng* it's not just mine. I can go on and on about how the *net* butchered the language, or how Singlish done us in for good. I can still imagine myself saying "u imba" thirty years from now too. However, it can never get too worrying, according to many Singaporeans who rightly (yea i tink so 2) believe that Singlish is unique; we ought to be proud of it. No matter what though, don't ever let your speech degrade to this sample MSN conversation-

“hi lol”
“hey ROFLMAOGAG”
“wut up lol”
“u c dakr nite????”
“ya lol”
“rip heath ledgere”
“ya, hez dead, rite?”
“ya, se u on myspace”
“k lol”
“bye rofl”
“k, by, lols”
