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.”

The Kamchatka Peninsula is a 1,250-kilometre-long peninsula in the Russian Far East, with an area of about 270,000 km².The Pacific Ocean and the Sea of Okhotsk make up the peninsula’s eastern and western coastlines, respectively.
There are a handful of things that separate the ultra-rich from everyone else: research has shown they tend to exercise regularly, maintain a healthy diet, save 10% or more of their income, read books and manage their time wisely.
But the most important — and most overlooked — a habit they share that helped them grow their wealth, in large part, is their commitment to forging valuable relationships with individuals they aspire to be: positive, success-minded folks.
