A DIALOGUE WITH SARAH, AGED 3: IN WHICH IT IS SHOWN THAT IF YOUR DAD IS A CHEMISTRY PROFESSOR, ASKING “WHY” CAN BE DANGEROUS
SARAH: Daddy, were you in the shower?
DAD: Yes, I was in the shower.
SARAH: Why?
DAD: I was dirty. The shower gets me clean.
SARAH: Why?
DAD: Why does the shower get me clean?
SARAH: Yes.
DAD: Because the water washes the dirt away when I use soap.
SARAH: Why?
DAD: Why do I use soap?
SARAH: Yes.
DAD: Because the soap grabs the dirt and lets the water wash it off.
SARAH: Why?
DAD: Why does the soap grab the dirt?
SARAH: Yes.
DAD: Because soap is a surfactant.
SARAH: Why?
DAD: Why is soap a surfactant?
SARAH: Yes.
DAD: That is an EXCELLENT question. Soap is a surfactant because it forms water-soluble micelles that trap the otherwise insoluble dirt and oil particles.
SARAH: Why?
DAD: Why does soap form micelles?
SARAH: Yes.
DAD: Soap molecules are long chains with a polar, hydrophilic head and a non-polar, hydrophobic tail. Can you say ‘hydrophilic’?
SARAH: Aidrofawwic
DAD: And can you say ‘hydrophobic’?
SARAH: Aidrofawwic
DAD: Excellent! The word ‘hydrophobic’ means that it avoids water.
SARAH: Why?
DAD: Why does it mean that?
SARAH: Yes.
DAD: It’s Greek! ‘Hydro’ means water and ‘phobic’ means ‘fear of’. ‘Phobos’ is fear. So ‘hydrophobic’ means ‘afraid of water’.
SARAH: Like a monster?
DAD: You mean, like being afraid of a monster?
SARAH: Yes.
DAD: A scary monster, sure. If you were afraid of a monster, a Greek person would say you were gorgophobic.
(pause)
SARAH: (rolls her eyes) I thought we were talking about soap.
DAD: We are talking about soap.
(longish pause)
SARAH: Why?
DAD: Why do the molecules have a hydrophilic head and a hydrophobic tail?
SARAH: Yes.
DAD: Because the C-O bonds in the head are highly polar, and the C-H bonds in the tail are effectively non-polar.
SARAH: Why?
DAD: Because while carbon and hydrogen have almost the same electronegativity, oxygen is far more electronegative, thereby polarizing the C-O bonds.
SARAH: Why?
DAD: Why is oxygen more electronegative than carbon and hydrogen?
SARAH: Yes.
DAD: That’s complicated. There are different answers to that question, depending on whether you’re talking about the Pauling or Mulliken electronegativity scales. The Pauling scale is based on homo- versus heteronuclear bond strength differences, while the Mulliken scale is based on the atomic properties of electron affinity and ionization energy. But it really all comes down to effective nuclear charge. The valence electrons in an oxygen atom have a lower energy than those of a carbon atom, and electrons shared between them are held more tightly to the oxygen, because electrons in an oxygen atom experience a greater nuclear charge and therefore a stronger attraction to the atomic nucleus! Cool, huh?
(pause)
SARAH: I don’t get it.
DAD: That’s OK. Neither do most of my students.
(The Dad is Stephen McNeil, "an Assistant Professor of Chemistry at the University of British Columbia Okanagan in Kelowna, British Columbia.")

this is really just the first five that popped into my head bc my favourite bands fluctuate a lot

☹ - Biggest pet peeve?

i think i answered this before but different one this time bc my driving test is in 2 days: when people don’t indicate while driving esp on roundabouts like god damn it is hard enough when people are doing things correctly

My (Skyrim/TES) personality type is RTMS. And I’m Okay with that.

The answer is: all of the above.

caterjunes:

what the fuck even is death note. i know there’s a guy named light and one named l (who named these children) and one of them looks like a spindly frog with emo hair, and of course there’s a notebook that gives people heart attacks, but then sometimes i see art of it and there’s this terrifying clown monster just sort of floating around in the background?? why is this juggalo here what does he want from the frog.

GUYS GUYS GUYS

GUARDIANS OF THE GALAXY WAS LITERALLY WRITTEN BY A FEMALE ROCKET SCIENTIST

SHE’S THE FIRST WOMAN TO EVER WRITE A MARVEL MOVIE

WHY IS THIS NOT GETTING TALKED ABOUT

So @TheCapitolPN tweeted this

which was promptly deleted. (G-Bb-A-D are the notes to Rue’s whistle.)

But if you had clicked inspect element before it was deleted

HOW COOL IS THIS MARKETING?!?! Like the rebels are hacking into the capitol’s twitter!!!!

I’m gonna kick this kid’s ass

my auntie is headteacher at the school that this kid goes to and apparently he asked to receive some sort of medal or something in assembly for this


i hope every person he meets goes hey you’re that fucking nerd boy
