View ArticleLessons from Mayan Astronomy [Cross-Listing]
The Mayan culture collected exquisite astronomical data for over a millennium. However, it failed to come up with the breakthrough ideas of modern astronomy because the data was analyzed within a...
View ArticleFolding Gravitational-Wave Interferometers
The sensitivity of kilometer-scale terrestrial gravitational wave interferometers is limited by mirror coating thermal noise. We explore the effect of folding the arm cavities of such interferometers....
