@MarkDHannam There is only one True Huge Book

I'm wondering what to read when I finish the huge book I'm currently on. Is there *another* huge book in my future? Uh oh. No. Please, not this one...

Volvo posted a 3 min and 46 second ad on Instagram, shot by Hoyte Van Hoytema, the cinematographer of Interstellar and Oppenheimer. It goes against every single rule you can think about as a social lead. Length. Format. Over-produced. Every comment under the ad said it immediately put Volvo in their consideration set. It's fucking fantastic.

@MarkDHannam You really flip this idea on its head here Mark!

It puts other thought leaders into perspective. Turns out you can say "he really flips this idea on its head" about anything at all! A pity the novelty wears off after about a minute...

I'm late to this, but just tried out notebookLM. I fed it my last blog post to turn into a podcast, and the results were hilarious, at least to me. Having a podcast talk about you as if you're a genius thought leader is wonderful... if only it was real! notebooklm.google.com/notebook/f07f6…

When you disagree with your reviewers and print out their reviews to tear them up.

.@LIGO @ego_virgo @KAGRA_PR 2023 @PhysRevX article "The population of merging compact binaries inferred using gravitational waves through GWTC-3" inspirehep.net/literature/196… reaches 1,000 citations. #topcites

@LIGO #ThrowbackThursday! 📷 Anyone Recognize This Location?? 🤓 Here's a photo from ~1995-97 showing hundreds of sectional pieces of what would become the Beam Tube Enclosure for @LIGOWA. The Beam Tube Enclosure houses the 4km Beam Tube for the X & Y arms. #construction

Garbage collection 🤔

New SPT-3G result! From CMB polarization alone we reconstruct the CMB lensing and an unlensed E-mode power spectrum. We find H0 = 66.8 ± 0.8 km/s/Mpc, in 5.4-sig tension w/ SH0ES, and mnu <0.075eV (95% CL), w/ weak (<3-sig) preference of excess lensing. arxiv.org/abs/2411.06000

calenderheads, peep february 2026. you don’t see em laid out like this often anymore. something to look forward to

It’s Europe for Harris with the Northwest in the lead - apart from parts of Southeast Europe.

This will actually be really useful and convenient for me (and the rest of Las Vegas)!
