@Curly_Fry15 @PhysInHistory The high temperature does not imply a lot of heat energy- the particles have very high kinetic energy so the temperature is high but they are widely separated so the total amount of energy is not great. Nowhere near enough to vaporise the craft. Next!

@Teamgrassroots_ Not enough for dissent yellow for me but could argue for a red for offensive, insulting, abusive behaviour. As the ref I might choose not to have heard it!

@Astronomer_Mark Hit it hard with a hammer a few times. Not sure whether it’s a heating effect or if it just dislodges bits of rust, but it might work!

@Curly_Fry15 @PhysInHistory Time spent travelling through the belts is very low giving minimal exposure to radiation. They can and I did!

@refsupportuk It really shouldn’t be about who makes the most/ biggest mistakes! Accept that an error was made and then move on. Applies to the officials and both teams.

@Hookean1 We pronounce it “foisty”. That might be just my family or Leeds or Yorkshire. If it’s the latter, then everyone else is clearly wrong!

@joel120193 MFA kit! Loved it back in the 80’s. Except the buzzer, that was a complete pain.

[Richard Fell @RichardFell13]

@joel120193 Looks like Magdeburg hemispheres- attach a vacuum pump and it is alleged that even a team of horses could not pull them apart.

@wladd73 @kelvmackenzie @truemagic68 Nope. It’s just “Third” nowadays!

@BenyohaiPhysics @ChatPhysics I’m surprised that Astro is the lowest of the aqa options and it’s also interesting that there’s about half a grade difference from the easiest to the hardest of the lines drawn. How big are the error bars btw?

A-Level Physics teachers. Would you would like to give your students a chance to read Physics case studies, then answer A-Level Qs on them? This resource might be useful. From the WJEC archive. Some lovely topics. I have others if needed. Pls RT! ⚡️📷 🚀https://t.co/WocxklBnb3

@DJGteaching The capacity to do work. Basically a way of accounting that underpins what happens when systems change.

[Richard Fell @RichardFell13]

@fenwhite @PhilHay_ @TheAthleticFC The force used was not negligible so it’s a red card. Stupidity from Meslier.

@staffdb66 Nucleus at a guess

[Richard Fell @RichardFell13]

@Hookean1 It is very misleading isn’t it- looks like the chain reaction involves ever lighter nuclei!

[Richard Fell @RichardFell13]

@refsupportuk The foul on Haaland involved contact and would not have been indirect so no confusion in signalling. Sometimes, people make mistakes- this is one of those I would say

[Richard Fell @RichardFell13]

@teacherhead @DJGteaching I wish I could have expressed these ideas so concisely and precisely. This thread should be compulsory reading for all leaders in education and indeed all teachers. Awesome!

@RuthPatchett1 @ChatPhysics @CLEAPSS @chatbiology @ChatChemistry It is the water model for teaching electricity.
