Time for another slow travel thread. This time from Dublin to Bilbao by rail and sail. We're catching the 17:28 from Dublin Connolly to Rosslare Europort. The train arrives 30 minutes early so it is easy to find a seat.

Before Ron Hellings passed away, he handed his calculus-based physics textbook off to me to finish up. It's been a long road, but I went into the exhibit hall here at the @apsphysics.bsky.social Global Summit and the book is out! @mitpress.bsky.social surprised me!

CLOSING MIDNIGHT TONIGHT engage.dublincity.ie/en-IE/projects/grow-college-green 🏰 A fantastic living room for our city 🙀 End the Dame Street nightmare ride 🚌 Keep good bus connections 🌿 Biodiversity and natural drainage 💚 Better health for all 🤔 Connections at each end, Church Lane need work 🚃

✨LISA Pathfinder officially began its science operations phase 10 years ago. Data collection continued through mid-June, followed by the start of science operations for NASA’s Disturbance Reduction System. 🛰️See LISA Pathfinder's journey here: youtu.be/GM8ZGJm-S7s?... #LPF10anniversary #LISAmission

Introduced in 2018 and expanded to all roads by 2020, Bilbao was the first European city of more than 300,000 inhabitants to adopt a universal 30 km/h speed limit. Several years on, the results suggest it has delivered broad benefits on safety, public health, travel efficiency, and quality of life.🧵

How can we best observe the most compact binaries with orbital periods as short as a few minutes, close to their final merger? They are strong supernova Ia progenitor candidates crucial to cosmology and are the strongest Galactic gravitational wave sources in the @lisacommunity.bsky.social regime 🔭

We mourn the passing of Professor Mike Cruise, who has died at the age of 78. The LISA Consortium extends its sincere condolences to Professor Cruise’s family, friends, and colleagues. Our thoughts are with them at this difficult time.

I'mq giving a virtual talk Saturday afternoon (2:30pm PST / 5:30pm EST) for San Francisco Mensa, called "Wormholes, Spacewarps, and Tunnels to Otherwheres." The talk is open for anyone! Register and get the link here: space-talk.link/FEB

I'll be doing a Webinar Tuesday night (17 Feb) for NASA's Night Sky Network, talking about the MILKY WAY and how we know what we know about our home galaxy. It will stream to YouTube live at 9pm Eastern (6pm Pacific). LINK: www.youtube.com/watch?v=QlW0...

Dublin airport has already recorded twice its normal monthly rainfall for February!

What I really love about this documentary is how in just a few minutes it shows the impact of the discovery—not just on science, but how it has inspired and motivated individuals, and how technology is finding applications in so many areas of life 🔭🧪⚛️🎢 #GW10Years

Gravitational waves constantly cross our Solar System. They travel in the fabric of spacetime, and, until recently, they did so undetected. But advances in technology have made measurements possible on the ground and, with our upcoming LISA mission, from space too 👉 www.esa.int/Science_Expl... 🔭

Stormy Scotman's Bay. Not the biggest waves I captured yesterday but I always love to get birds in my shots to add to the stormy atmosphere.

It's great to see Ireland exploring geothermal. Some information about @ucddublin.bsky.social's involvement in GEMINI here: www.ucd.ie/earthscience...

On my way to Boise to do some talks about LISA and gravitational waves. Did an interview this week with Idaho Matters on Idaho Public Radio about what we are going to talk about! Give it a listen! www.boisestatepublicradio.org/show/idaho-m...

What a wildly stupid idea. Mandatory helmets and high viz is a proven remedy to reduce the number of people cycling. It effectively kills off things like Dublin Bikes. That's why no other EU country does anything like this. Pure madness.

This is cycling in Copenhagen. No hi-vis. No helmet mandates. People cycle because it’s safe — by design. This is what cycling should look like. Ireland is moving in the opposite direction. Instead of designing safe places to cycle, we're blaming the people cycling...

Two years of pavement parking ban in Edinburgh and the sky has not fallen. Drivers have changed their behaviour. This makes a big difference to parents with biggies and people who use wheelchairs. Would be great to see this in Dublin. @dccbeta.bsky.social @dubcitycouncil.bsky.social

Ourselves, @dublincommuters.bsky.social, @galwaycommuters.bsky.social, & Cork Commuter Coalition wrote to Iarnród Éireann & the NTA today, asking them to cease posting real-time service updates exclusively on X.

Every now and again this gets recommended by an elected official, it’s obviously quite silly when you dig into it Private motorists don’t need more space when traffic is light, & when there is congestion buses need the priority

New map work! Greenways of Ireland. Something I've been wanting to do for a long time. Surprising just how many there are, and even more in planning #GreenwaysIreland #ActiveTravel #Cycling See more about the map on @irishcyclingcmpn.bsky.social here: www.irishcyclingcampaign.ie/greenways/

Today, 10 years ago, we had the first laser light on LPF! 💛🛰️ Laser interferometry was used on LPF to track the position of the test masses along the sensitive axis, and will be used on LISA too for the same purpose. #LPF10anniversary #LISAMission [Image credits: University of Glasgow]

Red light cameras left idle for a decade, draft plan left unfinished for 8 months but Govt says reducing road deaths “absolute priority” -- Law for enforceable variable-speed limits for the M50 and other major roads enacted in 2023.-- Much-ignored advisory square speed sign cannot be enforced.--…

A stunning sunrise over Dublin Bay this morning. Between the Bull Wall and Dublin Port, with North Bull Lighthouse silhouetted against a beautiful sky. Early morning birds along the shoreline and a beautiful sun pillar rising through the colours made it extra special. #dublinsunrise

A fiery sky, sun pillar and crepuscular rays over Ireland's Eye from Portmarnock this morning.

Poignant letter by Dr Lisa McNamee in the Irish Times this morning.

where my mind goes whenever people complain that a bike lane is a waste of space because it’s underused

Would be great to see this come to Ireland as well.

On this day, for #LPF10anniversary: following the successful separation from the launch vehicle, the mission operations team at ESOC undertook one of the most complex Launch and Early Operations Phases (LEOP) ever undertaken or an ESA mission. Watch it here 📽️ www.youtube.com/watch?v=maKX...

Aurora Borealis over Ireland's Eye tonight from Howth.

A fantastic report from Limerick with an unequivocal conclusion: the majority of Limerick’s protected cycle lane schemes “maintained or enhanced” access for emergency vehicles. Will our planners listen though? That is the question.

From LISA Pathfinder to LISA: Celebrating 10 years of LPF launch 🛰💛 "A fantastic mission. Everybody who worked with LPF felt in love with the mission." - Stefano Vitale, LPF PI

The best way to reduce congestion is to give people good alternatives to driving. This is why it is so disappointing to see the government put the DART+ South West scheme on the long finger.
