One to make Tim Harford gasp


We all mistakes, but the BBC's online report about the Nasa launch of its first rocket from an Australian commercial spaceport went through five versions and four edits - and eight hours! - before someone corrected a rather big numerical blunder.

But the data gathered in that time will help illuminate the secrets of star constellations 430 million light years away, says the chief executive of Equatorial Launch Australia, which runs the space centre.
"Without getting too deep into the science, it was effectively a large X-ray camera looking at various... phenomenon and trying to capture parts of boulders in the Milky Way and particularly the star cluster of Alpha Centauri," Michael Jones told the local network Nine.
But the data gathered by the mission's X-ray camera in that time will help illuminate the secrets of Alpha Centauri A and B, the closest double-star system to Earth that is located just 4.3 light-years away.

The earlier figure is a mere 100,000,000 times more than the correct figure.

The Oryx Handbook of Iranian Drones

Image
The goal of this list is to comprehensively catalogue Iran's past and current inventory of unmanned aerial vehicles (UAVs) and their armament. In an effort to streamline the list and avoid unnecessary confusion, this list only includes military drones associated with Iran's defence industry or military-grade UAVs with at least some chance of entering service. Notes:  - If several configurations of a drone with one designation are known, they are added as such.  - The part within the apostrophes refers to other designations or an unofficial designation. -  UAVs that did not enter service or have yet to enter service have been placed in the prototype category. - When a type is dual-capable, it is added in both respective categories. - Dubious claims are referred to as ''claimed to be capable''. - Although several types of Iranian UAVs have been sighted in Syria and Iraq, the foreign service section of this handbook only includes those confirmed to be in s

This Equation Shows You Can't Quantify Everything

Image
Yeah, I used a clickbaity headline. So sue me. Recently I went on an extensive rant about the fundamental assumptions of science. One of them, I said, was that things have to be measurable. And that's basically true, I think... but there are interesting subtleties. You might well be familiar with the weirdness of the quantum realms, as in the double-slit experiment where "particles" can apparently be in two places at once. What you might be less aware of is that much, much larger things can be just as hard to measure. You really don't need carefully controlled laboratory conditions to see how bizarre reality can get. Measuring some things is hard... In astronomy, if you're hunting for galaxies in a new data set, you have to try and estimate these things called completeness and reliability . They're quite simple concepts but they have very strict meanings - thankfully, for once, quite intuitive ones. Consider a naturalist trying to identify some meerk

Andrew Wyeth: Home Places

  THE BRANDYWINE   FEBRUARY 4–JULY 13, 2023 Andrew Wyeth, Swifts – First Version, 1991, watercolor on paper. Collection of the Wyeth Foundation for American Art B3122r © Andrew Wyeth/Artists Rights Society (ARS)  Opening at the Brandywine Museum of Art on February 4, 2023,  Andrew Wyeth: Home Places  presents nearly 50 paintings and drawings of local buildings that inspired Wyeth time and again over seven decades of his career. The artworks in this exhibition are drawn exclusively from the nearly 7,000-object Andrew and Betsy Wyeth Collection of the Wyeth Foundation for American Art, now managed by the Brandywine. Many of these pieces have never before been exhibited, offering a first glimpse at a significant treasure trove that will shed new light on the collaborative creative process of Andrew and Betsy Wyeth.
