In the deserts of Africa and the Middle East, scientists have discovered tiny tubes that appear to have been made by something alive. In a press release, researchers from Germany's Johannes Gutenberg University Mainz described their surprise upon finding these bizarre tubular tunnels in marble and limestone. "We were surprised," explained Cees Passchier, who first found the tunnels in Namibia 15 years ago, "because these tubes are clearly not the result of a geological process." In a new pape

Even the Kakeya set that overlaps the most has to take up some space, Fefferman found. That minimum volume depends on how thick the tubes are. Mathematicians quantify the relationship between the tubes’ thickness and the volume of the set using a number called the Minkowski dimension. The smaller the Minkowski dimension, the more you can reduce the set’s volume by thinning the tubes slightly. The three-dimensional Kakeya conjecture says that a set’s Minkowski dimension must be three. This const

There has been some spectacular progress in geometric measure theory: Hong Wang and Joshua Zahl have just released a preprint that resolves the three-dimensional case of the infamous Kakeya set conjecture! This conjecture asserts that a Kakeya set – a subset of that contains a unit line segment in every direction, must have Minkowski and Hausdorff dimension equal to three. (There is also a stronger “maximal function” version of this conjecture that remains open at present, although the methods o

In the mid-1960s, the Nobel Prize–winning physicist Luis Alvarez had a wild idea. He proposed using muons, highly penetrating subatomic particles created when cosmic rays strike Earth’s atmosphere, to search for hidden chambers within one of the pyramids of Giza. These muon particles are heavyweight cousins of electrons that travel close to the speed of light. They can penetrate through many meters of solid rock, including the limestone and granite blocks used to build the pyramids. But some of
