SAM: Folk in those stories had lots of chances of turning back only they didn’t. Because they were holding on to something. FRODO: What are we holding on to, Sam? SAM: That there’s some good in this world, Mr. Frodo. And it’s worth fighting for.

I'm so sorry - our budget was never meant to affect ordinary working people like Julie and John, with 60 rental properties and a boat.
🚀 It is a submission time 🚀 As a part of CLEO2025 Committee, we work hard on assembling great lineup of plenary and invited speakers. We invite all researchers and innovators in photonics to contribute with their groundbreaking work to the conference! 🔗 cleo2025.abstractcentral.com
In 2016, I destroyed my mental health by obsessively refreshing 538 and analyzing poll data and I am so excited to announce that 8 years later I am doing exactly that
Very sad to hear of the passing on 15 Oct of Wilson Sibbett CBE from @univofstandrews, ultrafast pioneer, mentor & dear friend to many. He won numerous honours from @OpticaWorldwide @rankprize @PhysicsNews @EuroPhysSoc @royalsociety Add your memories here rememberancebook.net/book/professor…

“Do you have a plan to improve NSS scores?” Well, I have the concept of a plan…
Everyone is freaking out over this, but there are many logical explanations. Although Starliner is *most* likely haunted, it could also be aliens, space whales, sophon interference, forever lost cosmonauts banging on the hatch begging to be let in, or simply the Babadook.

A really uncomfortable watch
Never even liked tennis anyway.
In four days, we could be seeing "unprecedented historical events" every eight hours until they are coming every four minutes
All I'm saying is that if *I* was trying to pull off the biggest jailbreak in history, I'd establish myself as the world's most beloved keycutter, and then get appointed Prisons Minister.
