Grand Teton National Park is an American national park in northwestern Wyoming.At approximately 310,000 acres (480 sq mi; 130,000 ha; 1,300 km2), the park includes the major peaks of the 40-mile-long (64 km) the Teton Range as well as most of the northern sections of the valley known as Jackson Hole. Grand Teton National Park is only 10 miles (16 km) south of Yellowstone National Park, to which it is connected by the National Park Service-managed John D. Rockefeller, Jr. Memorial Parkway. Along with surrounding national forests, these three protected areas constitute the almost 18,000,000-acre (7,300,000 ha) Greater Yellowstone Ecosystem, one of the world’s largest intact mid-latitude temperate ecosystems.
As anyone who counts a three-year-old among their acquaintances will know, there’s a fiery purity to the will of a small child that’s difficult to oppose. Once my son has figured out that there’s ice-cream in the freezer and decided he wants some for dessert, my role is equivalent to that of the ineffectual UN diplomat attempting to persuade a major nation-state to stockpile fewer weapons: good luck with that. Yet frequently, on receiving the ice‑cream, he’ll decide to let it melt before consuming it – then forget about it completely. He wants ice cream, monomaniacally, with a force his little frame almost can’t contain. But he doesn’t like it so very much that some other absorbing activity can’t banish it from his mind.
I only clearly grasped this distinction – and realized how it applies to me, too – when I encountered the findings of a study of coffee drinkers reported on the Research Digest blog. Using various psychological tests, researchers showed that “heavy” drinkers (those consuming three or more cups per day) had a much greater desire for coffee than those who consumed less of it, or none. But they took roughly the same, far lower level of pleasure as light drinkers when it actually came to drinking it. More serious addictions – to alcohol, or hard drugs – are characterized by a similar split between wanting and liking: you want the substance more and more, but like it less and less. And it’s been demonstrated that if you deprive people of a prize they want, they’ll desire it more; yet if they do then eventually acquire it, they’ll value it less.

Salzburg is an Austrian city on the border of Germany, with views of the Eastern Alps.The city is divided by the Salzach River, with medieval and baroque buildings of the pedestrian Altstadt (Old City) on its left bank, facing the 19th-century Neustadt (New City) on its right. The Altstadt birthplace of famed composer Mozart is preserved as a museum displaying his childhood instruments.
Stephen Hawking, who died in 2018 at the age of 76, was a physicist from another time.He had more in common with the celebrity scientists of the first half of the 20th century — especially the politically-inclined scientist-intellectuals like Robert Oppenheimer, Richard Feynman, and Enrico Fermi who came out of the Manhattan Project — than he did with any of his contemporaries. This isn’t so much a question of brainpower as it is of public positioning, as getting the public to understand new scientific ideas is a very different job than coming up with them. On the whole, our most prominent science communicators (Neil deGrasse Tyson, Bill Nye, Michio Kaku, etc.) do not actively produce science. Consequently, they are removed from the everyday slog and department politics that pervade the life of a working researcher. Meanwhile, our greatest researchers (a huge list of people I don’t want to enumerate for fear of leaving someone out) don’t prioritize telling the public what their work is and why it matters. Hawking, with his precise insights about physics and beyond who also possessed the power to capture the attention of the public, was a rare link between these two groups. Though some younger physicists like, for instance, Sean Carroll, a cosmologist at Caltech, and Lisa Randall, a particle physicist at Harvard, have similarly rare combinations of theoretical sophistication and an ability to communicate this sophistication clearly, the Hawking’s wide-ranging skills will be hard to replace. After all, I can’t think of anyone else who was able to both shape the modern understanding of black holes and make the only actually funny joke ever aired on The Big Bang Theory.

Physicists who have been roaming the “landscape” of string theory—the space of zillions and zillions of mathematical solutions of the theory, where each solution provides the kinds of equations physicists need to describe reality—have stumbled upon a subset of such equations that have the same set of matter particles as exists in our universe.
But this is no small subset: there are at least a quadrillion such solutions, making it the largest such set ever found in string theory.
According to string theory, all particles and fundamental forces arise from the vibrational states of tiny strings. For mathematical consistency, these strings vibrate in 10-dimensional spacetime. And for consistency with our familiar everyday experience of the universe, with three spatial dimensions and the dimension of time, the additional six dimensions are “compactified” so as to be undetectable.
A nebula is an interstellar cloud of dust, hydrogen, helium, and other ionized gases.Originally, the term was used to describe any diffused astronomical object, including galaxies beyond the Milky Way.
The town of Yokadouma lies in remote eastern Cameroon, close to the border with the Central African Republic, at a juncture of narrow roads that—when I visited, in May 2010, near the end of the long dry season—were unpaved and parched, their laterite clay pounded to powder by logging trucks rumbling north from the Republic of the Congo. The town’s name translates as Standing Elephant, and in the central roundabout stood an elephant statue, its tusks and part of its trunk broken off, rebar protruding. I checked in to the Hotel Elephant, whose dining room had a gorilla skull hung on one wall, a python skin stretched beside it. I remember the place because it was here, on the following morning, that I met my first pangolin, which was also my last.
A young man from the kitchen staff had just brought this piteous creature back from the town market. He carried it by its tail as it dangled, groggy, and helpless. It was reddish-brown, like the roadside trees, and for the same reason—it was caked with dust. The scales covering its head, body, and tail looked like rusty metal feathers. Pangolins are amazing animals, loosely known as scaly anteaters because of their armored skin and their diet, their elongated heads and their toothless mouths, though they aren’t closely related to true anteaters. In fact, they constitute a group of their own, one of the oddest of mammalian orders, the Pholidota, which contains only eight living species (the order of bats comprises fourteen hundred species). They are similar to carnivores by descent, and to armadillos by convergent evolution. They eat termites as well as ants, but they are virtually incapable of harming any other form of a living creature, except in their own defense.

The volcanoes of Kamchatka are a large group of volcanoes situated on the Kamchatka Peninsula, in eastern Russia.The Kamchatka River and the surrounding central side valley are flanked by large volcanic belts containing around 160 volcanoes, 29 of them still active.
In the 1991 German comedy film, Go Trabi Go, a family from the former German Democratic Republic (GDR) goes on a road trip to Italy in their beloved Trabant 601—the most popular car in East Germany before the collapse of the Iron Curtain. At one point their vehicle’s head gasket blows, and the father makes an emergency phone call. When he tells a mechanic over the line that he’s driving a Trabant 601, the mechanic chuckles and says, “I hope you’ve got some sticky tape.”
Over the years, the “Trabi” (as it’s affectionately known) has been the butt of endless jokes associated with East Germany. With its bare interior, oddly-designed stick shifter, and an exterior made of Duroplast—a rust-resistant, cotton-reinforced resin plastic that’s lighter and stronger than steel (and more importantly, could be manufactured in the GDR)—the standard four-seater Trabi sedan has been referred to as one of the “worst cars ever built,” and “East Germany’s terrible car that will never die.” Add to this its two-stroke engine, the same kind used in lawnmowers and Asia’s tuk-tuks, and it’s understandable why there are quips like “Why does a Trabi have a heated rear window? To keep your hands warm while you push.”
