How Steven Weinberg Transformed Physics and Physicists | Quanta Magazine
His first popular book — The First Three Minutes, about cosmology and the Big Bang — became an instant classic and proved profoundly influential for both the general public and professional researchers. Many physicists, including me, started learning cosmology from this book.
The First Three Minutes blew my little mind as a teenager. It has stayed with me.
Rotating Space Station Numbers
Ever wondered what would happen if you threw a ball inside an orbital habitat? Well, wonder no more!
You can adjust the parameters of the space station, or choose from some pre-prepared examples: an O’Neill cylinder, a Stanford torus, a Bernal sphere, Rama, a Culture orbital…
CERN Hack days – Chiteri’s Blog
Martin gives a personal history of his time at the two CERN hack projects …and also provides a short history of the universe.
A Briefer History of Time
You can read all of Stephen Hawking’s 2008 book online as a web book (kind of like Resilient Web Design).
The Case Against Quantum Computing - IEEE Spectrum
This is the best explanation of quantum computing I’ve read. I mean, it’s not like I can judge its veracity, but I could actually understand it.
Greetings, E.T. (Please Don’t Murder Us.) - The New York Times
Steven Johnson dives deep into the METI project, starting with the Arecibo message and covering Lincos, the Drake equation, and the Fermi paradox.
He also wrote about what he left out of the article and mentions that he’s writing a book on long-term decision making.
In a sense, the METI debate runs parallel to other existential decisions that we will be confronting in the coming decades, as our technological and scientific powers increase. Should we create superintelligent machines that exceed our own intellectual capabilities by such a wide margin that we cease to understand how their intelligence works? Should we ‘‘cure’’ death, as many technologists are proposing? Like METI, these are potentially among the most momentous decisions human beings will ever make, and yet the number of people actively participating in those decisions — or even aware such decisions are being made — is minuscule.
Is Dark Matter Hiding Aliens?
Here’s a fun cosmic hypothesis on the scale of an Olaf Stapeldon story. There are even implications for data storage:
By storing its essential data in photons, life could give itself a distributed backup system. And it could go further, manipulating new photons emitted by stars to dictate how they interact with matter. Fronts of electromagnetic radiation could be reaching across the cosmos to set in motion chains of interstellar or planetary chemistry with exquisite timing, exploiting wave interference and excitation energies in atoms and molecules.
SETI: A Networked Galaxy?
A fascinating guest post by Brian McConnell on Centauri Dreams: what if there’s a galactic equivalent to the internet, allowing civilisations to communicate with a system analogous to packet switching.
Unfortunately this kind of focussed signalling would be hard to detect. But on the other hand, it could explain the Fermi paradox.
Asteroid Day
This is an awareness project I can get behind: a Clarke-like Project Spaceguard to protect the Earth from asteroid collisions. This campaign will focus awareness of this issue on one single day…
Now if only the front page of this website actually said when that day will be.
Update: And now it does.
Staring down colliders
Craig recounts the time we visited the LHCb at CERN. It’s a lovely bit of writing. I wish it were on his own website.
Particle Fever
I can’t wait to see this documentary on the monumental work at CERN.
From Beyond the Coming Age of Networked Matter, a short story by Bruce Sterling
H.P. Lovecraft meets James Bridle in this great little story commissioned by the Institute For The Future.
Prometheus Fusion Perfection
Now this is what I call science hacking: building an open source fusion reactor.
Science!
An Ear for Science: The Particle Physics Windchime | SLAC News Center
The story of the particle windchime—it turns subatomic particle collisions into sound—created at Science Hack Day San Francisco.
Our world may be a giant hologram - space - 15 January 2009 - New Scientist
This makes my brain giddy. Dizzying stuff, clearly explained.
BallDroppings
Brendan Dawes pointed me to this wonderfully playful creation. It's Flash-free, believe it or not.
Crush the Castle | Armor Games
The game is simple, the physics are fun, the result is utterly addictive. Don't say I didn't warn you.
