November issue of Physics World is on Quantum Gravity

[marcus]

Physics World magazine is by subscription but some of their stuff is free online. This month's issue focuses on Quantum Gravity surveying string approach and loop gravity approach in a kind of balanced way

The string article is by Leonard Susskind
The Loop Quantum Gravity article is by Carlo Rovelli
The phenomenology article (discussing prospects for testing
quantum gravity models by actual observation and experiment) is by
Giovanni Amelino-Camelia

So it is a nice threeway split of emphasis between talk about string model, loop model, and real world testing.

You can get the magazine's website by Google. It is a UK journal run by the IOP (Institute of Physics) group called PhysicsWeb. Of the three invited articles, only Susskind's is free online. But Amelino-Camelia has posted an expanded version of his article at arXiv, so that is effectively online.

Interesting in the sense that it is 3 different perspectives on quantum gravity by 3 longtime leaders each of whom has a sense of the history and where the field is going. I haven't seen Rovelli's but
would not be surprised if it had some of the same overview as in his book "Quantum Gravity" to be published by Cambridge U. Press.

That sounds really interesting! I'm definitely going to check out the website and read the three articles. I'm sure it will be a great read and give me a better understanding of quantum gravity. Thanks for the info!

Thank you for sharing this information about the November issue of Physics World. It's great to see a balanced approach to discussing quantum gravity, with articles from leading experts in the field. It's also helpful to know that some of the content is available for free online, making it accessible to a wider audience.

The inclusion of a phenomenology article discussing the potential for testing quantum gravity models through observation and experiments is particularly interesting. It shows that the field is not just theoretical, but also has practical implications that can be tested and potentially verified.

I'm especially intrigued by the expanded version of Amelino-Camelia's article being available on arXiv. It's always helpful to have access to additional resources and perspectives, especially in a complex and evolving field like quantum gravity.

Overall, this issue seems like a valuable resource for anyone interested in learning more about quantum gravity. Thank you for bringing it to our attention.
