@docbrownchem When you say AQA won't accept averages, what *are* they expecting? Do they expect the students to identify the individual ox states of the different S atoms, as you do on your website?

[Chris Coates @CFCoatesDXB]

@docbrownchem It's +2 and +2.5 isn't it? I tell students that 2.5 is the *average* ox state of the S atoms, they aren't all the same (actually also true of the thiosulphate, it just so happens the average is an integer, so less controversial) which serves the purpose of counting the electrons

@Top10Nathan Not really a canon album but I really love Mixed Up (the remix album)

@docbrownchem IB mentions E/Z but not assessed. No R/S.

[Chris Coates @CFCoatesDXB]

@docbrownchem No isomerism in AP Chem. No organic at all, in fact!

@RogersHistory I co-wrote a textbook. Worked so hard to explain concepts with clarity. It went through so much editing. BUT also wrote loads of end-of-chapter questions and had to cut them down by more than half because they wouldn't fit on the assigned two-page spread. Publisher priorities!

Over a bunny is insane

@VinsodOfficial @jayforeman If we only McCartney music up to Dec 1980 I think it would still hold up better though

[Chris Coates @CFCoatesDXB]

@DoctorDemetris @jayforeman Oh, I know. I really like a lot of the Double Fantasy stuff. But I can't bear his manner, somehow, post-Beatles. The pomposity that he punctured so effortlessly back in '64 just kind of became part of his persona. And the gum chewing... Ecch

@Lloyd_Cole I went to the 20th anniversary reunion gig in Manchester. Drove over from Leeds. Fantastic gig. Was in awe of Neil's guitar playing. And now that's 20 years ago itself. Gosh.

@RealPaulPutner Another appearance of the yellow kneepads. Seemed to take a while for them to agree that green was definitive

@intellegint Mother's Pride and Prejudice?

@ArmandDAngour @guywalters I don't read Latin but I enjoyed the Life of Brian reference

@rhodri This is the Madeleine that has thrown me back into lockdown

@Ian_Fraser @SeasideChris So nearly a foot wider and two feet longer. The road footprint is about 30% bigger and the weight is almost 50% greater.

You’re a medieval peasant farmer.

You’re at the bottom rung of society—bound to the land with limited social mobility…

But life isn’t all bad. Here’s what it looks like🧵

@Jo_Moore_Sci In my experience, trust yourself and what helps the kids. We chopped it up to help learning, but also made it explicit how what we taught fits to the spec, so keen kids could make sense of it when pulling it together during revision. Good luck! Happy to offer advice in future.
