@xray_matt It seems like paramorphs are a special class of pseudomorph that are monomineralic and isochemical (the Venn intersection of pseudomorphs and polymorphs if you will).

[Mark Pearce @rockdoctormark]

@xray_matt I have never heard of paramorph but this paper seems to suggest it's one polymorph with the characteristic shape of another e.g. calcite shaped like aragonite needles.

Thank You, Tony Award-winning actress and singer Glynis Johns for wonderful performances on stage and screen. Send in the clowns has been much recorded but never bettered, and nobody dares take on Sister Suffragette.

Name a movie you've seen more than 7 times with just a gif.

@mcnamadd @manenbu @johneclogite I was thinking the other day that I worked on some of John's rocks collected the year I was born... the current class of undergrads were probably born the year some of our PhD rocks were collected #OldRocks

[Mark Pearce @rockdoctormark]

@mcnamadd @manenbu @johneclogite Well you probably collected the rocks in 2006 and we finished in 2008/9 🤔

@Transperth when can we expect a smart rider system where I can just update my autoloader details without needing to wait 24hrs then tag on and off. Or better yet, switch to EFT like most modern cities.

@lang_adin It's a shame the architects seem to have used the hospital for inspiration rather than the synagogue.

Mining can do all it wants to explain why the world needs its products for the global energy transition but if it doesn't address its shortcomings like improving its record on sexual assault and other DEI factors it will never be truely trusted @RohiteshDhawan at #WMC2023

Visibility is such an important part of overcoming homo/bi/transphobia and building understanding of our #diversity (remember the damage caused by Don't Ask Don't Tell or Section 28). It's a disgrace that such evil persists in contemporary Australia to target these lovely events.

@ProfRayWills @ToyotaMotorCorp We went to Toyota set on a hybrid RAV4 and they told us 18-24 months waiting so we said bugger that and went full electric Volvo XC40 and it arrived in 7 months. Nobody ain't got time to wait 2 years for a hybrid car.

@Shane__Mc @ProfRayWills There is no Fringe Benefit Tax payable on new EVs bought through a salary sacrifice scheme (e.g. novated lease) as long as they are not subject to luxury car tax*. https://t.co/OcZW45Oc0B *consult a tax professional to see if this scheme is right for you 😉
