- Happy solstice! At 09:20 UTC today the Sun reached the southernmost point in its annual latitudinal motion. From now on the amount of daylight in the northern hemisphere will increase until the June solstice.

- Yes indeed - 20 years ago …. I don’t think we’ve changed much :-)

- I think we should go for both - sort of like the 12 days of Christmas. A 2 week-long Feast of Astronomy.

- Huge congratulations - I agree that completing a PhD is both tremendously difficult and tremendously rewarding.
- [Not loaded yet]
- It does doesn’t it! Total bollocks.

- I could not agree more. I think most people vote optimistically - for the party they believe will offer a better future. Aiming for competence is not a compelling vision, although admittedly at the last election it was sufficient given the circumstances!
- I would add that Labour’s relaunch reads as a list of policies they would like to enact if the plan works. But I don’t see a plan. In 2025 (in my view) they will have to either set the country on trajectory to rejoin SM and CU or align more closely with US. Rudderless mid-Atlantic is unsustainable.
- All of this and more. Not only does the government not 'speak human' or have a good story about what it wants to achieve, it also doesn't have a particularly convincing account of the country or the world as it is. www.theguardian.com/commentisfre...

- I don’t agree. I can’t see the big picture - what is the U.K’s place in the world? Are we to regain our place in Europe or attempt to be a lower-tax, deregulated country which is more US facing? The big strategic questions can’t be dodged much longer.

- It’s called Titanic.
- [Not loaded yet]
- Yes. I’m pretty fed up with ‘red lines’.
- [Not loaded yet]
- I still agree with myself - I think that was 2014!

- It is the same, yes. Which leads to the twins paradox. The resolution is the symmetry between the clocks is broken when one accelerates (changes direction) to return and meet the other. If you google it, note that the AI summary is wrong. You don’t need General Relativity to deal with the problem.
- Spent the day at Boulby Underground Lab near Whitby - 1.1km underground. Dark matter searches, neutrino physics, very low cosmic ray and background radiation suitable for (amongst many other things) quantum computing. It’s a pretty unique facility and the mine is remarkable - over 100km of tunnels!

- Everyone has to have the same protection going down there whether they are mining or not - so I suppose it’s to do with mining!
- [Not loaded yet]
- It’s a very impressive operation. The first time I went down was in the late ‘90s. Maybe he was as manager then?
- I finally started watching The Last of Us (I know I’m very late) and now I’m paranoid about getting athletes foot.

- Greenfield originally. I used to live in Lydgate.

- My family are from Saddleworth which really should be thought of as the West Riding of Yorkshire. Although I was born in Oldham and that is certainly Lancashire.
- [Not loaded yet]
- [Not loaded yet]
- Yes. I’m the real one!

- That’s great - say hello from me !
- [Not loaded yet]
- [Not loaded yet]
- No - just under I presume !
- And one last picture of my cat, just to round off this initial short series of physics and cat posts, this time with my radiator also in shot.
- [Not loaded yet]
- That’s Taiyō …
- [Not loaded yet]
- I thought you’d be more interested in the biology than the engineering :-)
- [Not loaded yet]
- It’s not me to be fair - it’s Einstein. And yes, he’s right.
- [Not loaded yet]
- Won’t work. AI’s are sort of Californian and I’m from Oldham. Far more difficult to replicate.
- [Not loaded yet]
- Yes!
- [Not loaded yet]
- [Not loaded yet]
- Yes indeed!
- [Not loaded yet]
- It’s the breed. I think it comes from the American Curl I initially
- [Not loaded yet]
- It’s just the rate of change of position generalised to spacetime. So velocity = dx/dt basically. Think miles per hour …

- The problem with that joke is that everything with mass or energy generates its own gravity field.
- Here’s a picture of my cat asleep with its feet on its head. I can’t do this.
- [Not loaded yet]
- I’ve got more chance of doing that than putting my feet on my head to be honest ..
- [Not loaded yet]
- Is he on here - is it the real Dara ?
- [Not loaded yet]
- [Not loaded yet]
- Thank you :-)

- [Not loaded yet]
- But both phones would end up in the phone bag they make you put your phones in. Watch would work
- [Not loaded yet]
- I would recommend it of course - if you have the time and resources which is obviously a big if !
- [Not loaded yet]
- I just don’t like the k …
- [Not loaded yet]
- Thanks - I’ll look into that …
- [Not loaded yet]
- Yes. I think it’s ultimately doing the audience a favour - although you can’t buy a beer using Apple Pay ….
- [Not loaded yet]
- Maybe the other one is him.
- [Not loaded yet]
- Nice.
- [Not loaded yet]
- Also note that E =gamma mc^2 would appear to imply that massless particles should have zero energy - BUT for massless particle travelling at c, gamma goes to infinity and so the expression is undefined. Then we have E =pc from the equation in the notes. Nice :-)

- I meant to type ‘kind of nob’ but I agree that can of nob is better
- [Not loaded yet]
- It’s worth a try though
- [Not loaded yet]
- Yep.
- [Not loaded yet]
- It’s great stuff :-)
- [Not loaded yet]
- Yo momma has such a large invariant mass that …..
- [Not loaded yet]
- I’m the real one - and I can prove it by noting that the others are nob ends.
