View of the side facade of Prado Museum in Madrid, statue of Goya in the foreground, beautiful blue sky

Sheffield to Madrid by train! Visited Complutense University in Madrid for a few days. First day Sheffield-Montpellier - TGV in France fast and efficient as always, fantastic views! Then direct from Montpellier to Madrid with even better views from the train. @seatsixtyone.bsky.social

View from Siegessäule (Victory Column) in Berlin. One can see Tiergarten in the foreground and Reichstag, Alexanderplatz TV Tower, Brandenburg Gate, Dom and various other attractions in the background. Mostly blue sky with a few small clouds

View of downtown Warsaw from the viewing platform on top of the Cultural Palace. It is an interesting mixture of modern towers and old socialist prefab-concrete construction. Sunny sky

A picture showing that I was indeed in Seat 61 (on the Warsaw-Krakow fast train). It's a window seat indicated by "Okno-Fenster-Okno-Window".

View over the famous main square in Krakow. St Mary's Basilica in the background and Cloth Hall visible in the central-right part of the picture. It's clear blue sky and a very hot day. There is a sprinkler for cooling down people with water. One can also see market stalls.

Another train travel adventure in Europe! Sheffield to Berlin, then Warsaw and Krakow (including a tour of Auschwitz). Lots of cultural and social experiences - the journey back from Krakow only took two days 😀 Even managed to be in Seat 61 once! @seatsixtyone.bsky.social

Or perhaps it's Green to Lib Dem & SNP.

View from Calton Hill towards Edinburgh city centre, with castle in the distant background. Clear blue sky!

Exciting few days in Edinburgh 🏴󠁧󠁢󠁳󠁣󠁴󠁿 - visited the University and today sightseeing and a hike up Arthur's Seat!

We didn't dream it! 😡💥
The respectful way Keir Starmer talked about foreign workers when he was running for Labour leader is the exact OPPOSITE of the Farage-cloned way he talks about them now. But to see it here in black & white is still SHOCKING!

Bank holiday hike from Hathersage up to Stanage and Higger Tor. So beautiful

A table showing the number of imes teams have won the Premier League in ascending order. The sequence goes 1, 1, 2, 3, 5, 8, 13 - the first seven terms of the Fibonacci sequence.

As Liverpool win the Premier League for the second time, they complete the opening of a quite remarkable sequence, 33 years in the making.

Schwabentor, one of the medieval gates in Freiburg. There's a painting of St George as dragon slayer and the inscription "St. Georgius patronus freiburgi", which is Latin I think

LEGO model of Notre Dame and the square in front of it during the time of the French revolution. There's actually a guillotine installation and you can see Marie Antoinette awaiting her execution, with some severed heads.

Selfie in front of Notre Dame cathedral in Paris, grey sky.

Returning to England on St George's Day, as seems appropriate. They love St George in Freiburg too! On the way back, time to see Notre Dame both in Kaiserslautern (as Lego) and finally again in Paris!

Münsterplatz in Freiburg. Cathedral on the right and Historisches Kaufhaus on the left. Some market stalls in the middle

Waldtraut vom Mühlwald, known as Germany's tallest tree. It's a Douglas fir, about 100 years old

Fantastic view over Black Forest landscapes with a partially cloudy sky

Exploring Freiburg and the Black Forest. Found Germany's tallest tree!

Black holes: Not endings, but beginnings? Theoretical study delves into 'white holes' Our understanding of black holes, time and the mysterious dark energy that dominates the universe could be revolutionized, as new University of Sheffield research helps unravel the mysteries of the cosmos.

New theoretical insights suggest black holes might not be endpoints but transitions to white holes, potentially reshaping our understanding of time and dark energy in the universe. doi.org/g8748h

Black Hole Singularity Resolution in Unimodular Gravity from Unitarity - our work in Physical Review Letters today: journals.aps.org/prl/abstract...

Kingfisher sitting on a branch of a tree above some water in Endcliffe Park

Kingfisher in Endcliffe Park in Sheffield - not a great quality picture but very exciting!

Picture of a small meeting room with about 10 chairs around a table, a not too big TV and a whiteboard.

Today I realised that this is where I'm supposed to be delivering lectures in a few weeks. Not too sure how I can make this work yet...

Selfie in front of Reichstag building in Berlin. Giant Christmas tree visible in front of Reichstag

Misty view over Berlin darkness from Neue Nationalgalerie Museum. Cranes in the foreground and hotel neon lights in the background visible through the mist.

Overground S-Bahn in Berlin, station entrance Tiergarten with an old pub that offers "Warme Speisen", graffiti and bins

Selfie in the Berlin underground (U7 Karl-Marx-Str.) at 3:15am

Berlin at the end of 2024. Believe it or not, the U-Bahn runs at 3:15 on a Tuesday morning.

View of Gtech Community Stadium from near a corner after the match has finished. Most people have left.

Road signs at Ealing Road, Brentford. Sign towards the left says "Brentford F.C." whereas one pointing to the right says "Brentford Community Stadium"

View over the Thames and London sights, London Eye on the left, Parliament and Big Ben on the right. Intense sunlight

St Paul's Cathedral at night, illuminated and with a Christmas tree in front.

No points at home this time, sadly. On the plus side, time for lots of cool London sightseeing and a long visit to the Tate Modern.

Side view of Old Trafford stadium in Manchester, with the text "Manchester United". Quite nice almost blue sky

Selfie inside Old Trafford stadium Manchester, with "Stretford End" visible in background.

Old Trafford today. Now the 14th football ground I have visited in England. Uwe's granddad bombed the Stretford End. Sadly no points (as usual away from home)

I played this on C64. Great game!

view from Flamborough Head, East Yorkshire, chalk cliffs and sea in background

view of cliffs and sea near Bempton, large number of birds (gannets) visible on the cliff

view of Ravenscar hill with coastline and sea

view of parts of Whitby abbey, grey sky and misty background

Exploring the Yorkshire coast - pretty exhausted after 4 days of hiking 👴🛌😂

Maybe you can stick around for longer next time. We actually invented football 😀

View of a main road near Brighton seafront, Brighton i360 in background. Sun close to sunset in background

View of the sea at Brighton beach on a windy day. Grey sky and a lot of waves on the sea.

Selfie in front of cliff and coastal path on Sussex coast. Weather fairly nice.

Mini break visiting Brighton and the beautiful Sussex coast. It's been so long since I've done something like this and it is so easy to organise.

A Greggs coffee and breakfast roll on table with Tyne Bridge in the background

Breakfast next to Tyne Bridge for £2.85 -- talk about value for money 😀 #newcastle

I'd support your MP if you agree with them. MP's stay for decades, leaders move on. We have seen Labour oscillate between left-wing and centre-right in just a few years and the same can happen again.

This was covered this week in "More or less" on Radio 4 I think
It says "best vote share in ANY general election"

The highest LibDems ever achieved in C Devon was 34.4% in *2010*. The highest Labour achieved was 27% in 2017.

The argument being that because of 2010, LibDems are the main challengers

"Labour is committed to the nuclear deterrent triple lock" with a picture of sir kid starver looking aggressively Sensible (or his best approximation of this at least)

Man I just want slightly nicer trains

Also, wearing a football shirt seems to have a similar effect to walking around with a cute pet/small child in that random strangers all start talking to you 👍
