Hey #ChemTwitter gotta mystery for you. A friend painted my nails with a UV-cured gel. It was pink when it went on. Over the next 48 hours, it’s increasingly turned yellow (lighting is different in pics but I think you can see...) 1/2 ImageImageImage
... what could possibly have caused this? I haven’t handled anything (that I can of) that might cause discolouration or pigment breakdown. Friend has painted her own nails same colour since, no change yet. It’s apparently me! 🤷🏼‍♀️
2/2
Quick add: could it be hand sanitiser perhaps? IPA? Ethanol?
I found this sort-of-similar experience, but this woman never got to the bottom of it either... lohud.com/story/news/201…

For #WorldEngineeringDay and with #InternationalWomensDay coming up, here’s a thread of five female engineers #WomenInSTEM 🧵 🪡

(By the way, #TransWomenAreWomen)
Edith Clarke was the first woman to be awarded an electrical engineering degree from MIT, and the first woman to be professionally employed as an electrical engineer in the US. She worked on the hydroelectric systems that, to this day, provide hydropower at the West Hoover Dam. Black and white, early 20th century photo of Edith Clark: a
Mary Jackson was a mathematician and aerospace engineer at NACA, later to become NASA. She was NASA's first Black female engineer. She particularly worked in understanding air flow, including thrust and drag forces—important for aircraft design. Mid-20th century black and white photo of Mary Jackson: a Bl

Another thread of easily confused words, you say?

Oh all right then! 🧵

((un)fortunately there’s plenty of material, because English is a pain in the neck*)

(*when did it become bum/backside/arse? Surely a pain in the neck is worse…?)
allude: indirectly call attention to something (“she alluded to the events of last Friday”)

elude: escape from something (“they eluded their pursuer”)

Similar-sounding but with two different meanings. Remember to ALLude means to cALL attention.
which reminds me of…

peruse: examine carefully

pursue: chase/continue along

It only takes a small slip for autocorrect to bite you here. Imagine splitting the words –PER USE vs. PUR SUE – and remember someone might purSUE a legal claim where someone else was SUEd.

Right, let’s do some more easily-confused words!

Plus hints to (hopefully!) help you remember which is which…

🧵
Pour: to make liquid flow

Pore: a small opening
OR, gaze intently (she pored over the map)

Imagine the U in poUr is a cup. You wouldn’t want to spill anything on your important documents!

(There’s also “poor” but that doesn’t seem to cause so much trouble)
Discreet: careful in speech/actions, or deliberately unobtrusive

Discrete: individually separate/distinct

This one’s easy: the two Es in “discrete” have a T between them, so that’s the one that means separate…

I am a proofreader. Would you like a list of words which are very nearly, not not quite, the same?

Of course you would 😆
All right… 🧵
Forgo: opt out/abstain

Forego: go before

(Remember FOREgo means beFORE)
Complement: completes something/adds features

Compliment: a nice thing to say

(I always find myself double-checking this one. Remember compLEment means to compLEte)

I’ve been asked to make a post about my twisty-turny career for #YoungScientistNetworking, because not all PhDs end up in academia. So, here goes… 🧵
1/8 Image
I finished my chemistry PhD in 2000, at Nottingham University (home of @periodicvideos!). I briefly contemplated working for Bio-Rad, because I’d done a lot of infrared spec, but instead I joined UoN’s web design team (it was a pretty new thing, then)
2/8
After two years I decided I missed the science. So I left to complete a teacher-training course. I’d go on to teach secondary science, particularly chemistry, on and off for nearly twenty years
