I recently enrolled on an edX home study course, Quantum Mechanics for everyone. I enrolled because Quantum Mechanics boggles my mind and It fascinates me. Today I learned that the graphical representation of the atom that is still frequently used today is actually wrong. The nucleus is displayed much larger than it actually is, electrons are shown to be vastly larger and to orbit the nucleus. The nucleus is 100,000 times smaller than the atom, electrons don't really orbit the nucleus and we have yet to find any length scale at which an electron has structure. That pretty much bucks what we were taught in GCSE physics (from what I do remember) way back in the late 80's! Kind of makes me feel old.
If it makes you feel better, I was taught this structure of an atom at GCSE too and I did mine in '02. At A-level however we started discussing the idea of electrons as a cloud IIRC, which we also discussed in chemistry too. I believe this model in your pic was taught earlier because it's easier to visualise and work with.
I for one don't care as is still a great image, it is the same with dinosaurs most depictions are totally wrong with them now proved to be covered in feathers or similar. A feathery Tyrannosaurus Rex just isn't right even if it correct.

Don't forget this: "If you think you understand quantum mechanics, you don't understand quantum mechanics." Richard Feynman. Physics was my favourite subject, studying for GCEs in the late seventies but, understanding of quantum mechanics completely eludes me.
Explaining quantum physics isn't about explaining quantum physics, it's about sharing the headache around --Jim Al-Khalili
I have seen Jim Al-Khalili's programmes on BBC4, they were very interesting, helped by being aimed at intelligent people.
Pretty much bang on, I know a little but reading it is akin to trudging through syrup in a force 10 gale while dragging a small car full of cement with an anchor attached.
From what I've seen, it's for when the pan is full; clingfilm over it heavily and then you can press on it and it acts like a plunger. But in my 31 years I've never blocked a toilet, despite the odd bowel movement that would have King Kong do a double take.
We've got two toilets in the house, a modern low volume flush and an old school 1.5m of head toploader. I pick my battles.
Don't forget to remove said clingfilm before wife goes to pee..... from experience, they get really angry!!

That you need to be careful who you tea bag... https://www.eteknix.com/game-developer-faces-sack-tea-bagging-journalist/
I'm not really too familiar with eteknix, and after reading that article this situation probably won't change. Absolutely nothing whatsoever is cited to state that this dev is facing the sack: no press release, no statement, no "industry insider" or "sources close to the matter", no twitter rumours... Admittedly I'm not that familiar with the story so that stuff could be mentioned in other reporting elsewhere, but it's not referenced in that article at all. The only thing that is referenced is the twitter feed of the journo in question, and I see nothing there that calls for someone to get the sack. Based on that article, the only real story here is that someone called out teabagging as a bit of a d!ck move and something you probably shouldn't do during a press demo.
I started doing some digging on it; I can't find any solid evidence one way or the other and I can't see a single attempt at an unbiased article. Right now the whole thing sounds like a storm in a tea cup (pun most definitely intended).
