In addition to undergoing wild price swings on a regular basis, Bitcoin and other cryptocurrencies are also consuming massive amounts of energy, enabling criminal activity, and creating new financial risks. Their booming yet unfathomable popularity demands an urgent regulatory response.
The price of Bitcoin has undergone yet another wild gyration, rising from $41,030 on September 29, 2021, to $69,000 on November 10, 2021, before falling back to $35,075 on January 23. That is its second-largest decline in absolute value, though it has suffered larger declines in percentage terms, such as between December 15, 2017, and December 14, 2018, when it fell by 83.8%. More broadly, the cryptocurrency market (comprising some 12,278 coins) was estimated to be worth $3.3 trillion on November 8, 2021, before plummeting to $1.75 trillion as of January 30.
A private digital asset based on a distributed ledger technology known as “blockchain,” Bitcoin is used as a decentralized digital currency – a peer-to-peer electronic cash system. With no intrinsic value, its market valuation (in terms of US dollars) is nothing more than a bubble.

Misperceptions threaten to warp mass opinion and public policy on controversial issues in politics, science, and health. What explains the prevalence and persistence of these false and unsupported beliefs, which seem to be genuinely held by many people? Though limits on cognitive resources and attention play an important role, many of the most destructive misperceptions arise in domains where individuals have weak incentives to hold accurate beliefs and strong directional motivations to endorse beliefs that are consistent with a group identity such as partisanship. These tendencies are often exploited by elites who frequently create and amplify misperceptions to influence elections and public policy. Though evidence is lacking for claims of a “post-truth” era, changes in the speed with which false information travels and the extent to which it can find receptive audiences require new approaches to counter misinformation. Reducing the propagation and influence of false claims will require further efforts to inoculate people in advance of exposure (for example, media literacy), debunk false claims that are already salient or widespread (for example, fact-checking), reduce the prevalence of low-quality information (for example, changing social media algorithms), and discourage elites from promoting false information (for example, strengthening reputational sanctions).
In August of 2019, a special issue of the Times Magazine appeared, wearing a portentous cover—a photograph, shot by the visual artist Dannielle Bowman, of a calm sea under gray skies, the line between earth and land cleanly bisecting the frame like the stroke of a minimalist painting. On the lower half of the page was a mighty paragraph, printed in bronze letters. It began:

Some time in the tense winter of 1983, when Nato forces rehearsed a nuclear endgame to the Cold War so realistic that Soviet counter-intelligence briefly suspected it to be a cover for a real attack, a Stasi officer read out a stream-of-consciousness poem to a fellow intelligence operatives inside a heavily fortified compound in East Berlin.
De Francesco’s book is a fascinating historical examination of the charlatan figure that remains valid. Drawing on a variety of historical sources, de Francesco traces this path through early modern Europe, dwelling on alchemists, worm doctors, magnetizers, prestidigitators, and mountebanks. Individuals making an appearance include long-forgotten gold-makers like Leopold Thurneißer and Marco Bragadino, purported revenants like the Count of St. Germain, self-styled healers like Doctor Eisenbarth and James Graham, magicians like Jacob Philadelphia, and occultists like the Count Alessandro di Cagliostro. De Francesco, who sometimes comes across like a phenomenological sociologist in the tradition of Walter Benjamin or Siegfried Kracauer rather than an art historian, manages to distill the traits and behaviors of all these historical figures to an archetype.
Gary Shteyngart has quietly become one of the most talented comic writers working in English today. More or less uniquely, apart maybe from bits of Zadie Smith, he’s even funny on the subject of identity. He’s also good on both Tom Wolfe’s ‘right – BAM! – now’ and J G Ballard’s ‘next five minutes’, having trained his lens on the brutal carnival of post-Soviet Russia in Absurdistan, the impact of tech on the mating habits of youngish Americans in Super Sad True Love Story and the fallout of the financial crisis of 2008 in Lake Success. If all that were not enough, he’s an unusually acute observer of a certain strain of male sexual anguish that some of his predecessors might have treated with an indulgence bordering on mysticism, but which most of his contemporaries now seem to view as little more than an abstract social problem or a handy plot device.
For centuries, writers have mused on the heart as the core of humanity’s passion, its morals, its valour. The head, by contrast, was the seat of cold, hard rationality. In 1898, US poet John Godfrey Saxe wrote of such differences, but concluded his verses arguing that the heart and head are interdependent. “Each is best when both unite,” he wrote. “What were the heat without the light?” At that time, however, Saxe could not have known that the head and the heart share a deep biological connection.

Our species owes a lot to opposable thumbs. But if evolution had given us extra thumbs, things probably wouldn’t have improved much. One thumb per hand is enough.
Every medium of communication has its own attentional norms. Like all tacit rules that govern behavior, they get violated, but the violators typically act deliberately. For instance, the people who talk aloud in the movie theater typically aren’t ignorant of the norms; they transgress them for the lulz. Human beings are extremely skilled at recognizing and internalizing the norms of any given medium or environment.
The Royal Geographical Society encouraged the Royal Navy to support British expeditions of Antarctica in the early 1900s. Heading from New Zealand, the expedition ship Discovery anchored off the coastline of the unknown land under the leadership of Captain Robert Falcon Scott. He chose the Anglo-Irish ex-Merchant Navy Third Officer, Ernest Shackleton, to lead the first hazardous sledge journey inland over slippery surfaces at temperatures as low as minus 62 degrees Fahrenheit. They aimed to make history by breaking the furthest South record towards the bottom of planet Earth.
