It's going to be a few days before the next "Big Question" post. In the meantime, I thought I'd let the scientific luminaries speak for themselves:
The New Scientist has asked top scientists from a variety of fields to "forecast the future." I was particularly struck by Oliver Sacks' and Antonio Damasio's predictions. And those who found the "Quantum Physics for Artists" entry intriguing will want to check out Nobel Prize winning Theoretical Physicist Gerard 't Hooft's submission. Hooft believes that physicists will construct "a theory that not only unites quantum mechanics and gravity, but also predicts every single detail of the evolution of the universe," within the next 50 years.
If that whets your appetite, you may want to spend some time browsing the "Dangerous Ideas" on display over at The Edge. They're a bit older, but no less fascinating.
