It’s Been 30 Years Since ‘Masked Rider’ Tried to Give ‘Kamen Rider’ Its ‘Power Rangers’ Moment

When audiences were in the grip of Power Rangers mania in the early ’90s, Saban Entertainment sought more ways it could leverage its relationship with Japanese studio Toei to turn even more Tokusatsu series into U.S. hits. Thirty years ago today, Saban debuted its take on one of the medium’s most legendary entries, Kamen Rider, hoping the next Power Rangers was in its hands. Instead, audiences got Masked Rider, and Kamen Rider‘s own journey to the U.S. would take the long way round over the nex

The Value of Bringing a Telephoto Lens

They usually aren't light, and they certainly aren't small, but the unique perspective a telephoto lens brings makes it an indispensable part of your kit, even when traveling. Let's review some shots taken with a telephoto to see how we can justify its size and weight. Avoiding Distractions In some cases, distracting buildings or people may be unavoidable. However, a telephoto can help eliminate those distractions and bring your subject, in this case the clouds and mountains, front-and-center:

Wiggling into Correlation

Jeff Kaufman shared some data around contra dance attendance as a function of requirements on wearing surgical masks. He compares this data to survey data, which is a useful way to validate in both directions. I found the plot compelling for a different reason – depending on how we look at it, we can draw wildly different conclusions from it. On the one hand, if we draw boxes around consecutive pairs of dances, it’s fairly obvious that mask-optional dances are more popular. Tickmarks at the top

Fix damaged art in hours with AI

In his study, Alex Kachkine, SM ’23, presents a new method he’s developed that involves printing the restoration on a very thin polymer film that can be carefully aligned with a painting and adhered to it or easily removed. As a demonstration, he used the method to repair a highly damaged 15th-century oil painting he owned. First he used traditional techniques to clean the painting and remove any past restoration efforts. Then he scanned the painting, including the many regions where paint had f

Was Jesus Really Wrapped in the Shroud of Turin? 3D Study Says Probably Not

The Shroud of Turin is an ancient linen cloth with the subtle impression of the front and back of a crucified man. While many believe it was the burial shroud in which Jesus was wrapped when he died in the 30s CE, scientific research has dated it to between 1260 and 1390 CE, suggesting it’s a medieval artifact. An ingenious new approach using 3D scans is now adding further credence to the suggestion that Jesus’s body—or any body for that matter—never touched this famous fabric. Cicero Moraes, a

A Wild New Take on ‘Phantom of the Opera’ Is Coming, and No One Has Any Idea What It Is

For the past few months, Phans (The Phantom of the Opera fans) have been following mysterious messages and clue drops around New York City for something called Masquerade. Talk online abounded about the roses left in Times Square or the red envelope letters signed by “the Opera Ghost” for the faithful, as a viral campaign teased that something was coming in the realm of immersive theater. As a big Phan and immersive theater nerd, I’ve waited from the far wings on the West Coast with major FOMO f
