New particles may yet be discovered, and even new laws. But it is almost taken for granted that everything from physics to biology, including the mind, ultimately comes down to four fundamental concepts: matter and energy interacting in an arena of space and time.

What makes “Mind and Cosmos” worth reading is that Dr. Nagel is an atheist, who rejects the creationist idea of an intelligent designer. The answers, he believes, may still be found through science, but only by expanding it further than it may be willing to go.

“Humans are addicted to the hope for a final reckoning,” he wrote, “but intellectual humility requires that we resist the temptation to assume that the tools of the kind we now have are in principle sufficient to understand the universe as a whole.”

Astronomers announced on Tuesday that they had found eight new planets orbiting their stars at distances compatible with liquid water, bringing the total number of potentially habitable planets in the just-right “Goldilocks” zone to a dozen or two

As the ranks of these planets grow, astronomers are planning the next step in the quest to end cosmic loneliness: gauging which hold the greatest promise for life and what tools will be needed to learn about them.

recalled that the first discovery of a planet orbiting another normal star, a Jupiter-like giant, was 20 years ago. Before that, she said, astronomers worried that “maybe the ‘Star Trek’ picture of the universe was not right, and there is no life anywhere else.”

Instead of self-confident and self-centered answers, the author humbly asks fundamental questions: What is economics? What is its meaning? Where does this new religion, as it is sometimes called, come from? What are its possibilities and its limitations and borders, if there are any? Why are we so dependent on permanent growing of growth and growth of growing of growth? Where did the idea of progress come from, and where is it leading us? Why are so many economic debates accompanied by obsession and fanaticism?

The majority of our political parties act with a narrow materialistic focus when, in their programs, they present the economy and finance first; only then, somewhere at the end, do we find culture as something pasted on or as a libation for a couple of madmen.

most of them—consciously or unconsciously—accept and spread the Marxist thesis of the economic base and the spiritual superstructure.

Fifty years after humans first left bootprints in the lunar dust, it’s an enticing idea. The effort and the commitment of brainpower and money, and the glorious achievement itself, shine as an international example of what people can do when they set their minds to it. The spinoff technologies ended up affecting all of our lives.So why not do it all over again — but instead of going to another astronomical body and planting a flag, why not save our own planet?

But President Kennedy did not have to convince people that the moon existed. In our current political climate, the clear evidence that humans have generated greenhouse gases that are having a powerful effect on climate, and will have a greater effect into the future, has not moved the federal government to act with vigor. And a determined faction even argues that climate change is a hoax, as President Donald Trump has falsely stated at various times.

The task of reversing that accumulation of greenhouse gases is vast, and progress is painfully slow.

By 1935, the New Dealers had set up a new agency, the Securities and Exchange Commission, and cleaned out the FTC. Yet there was still immense concern that Roosevelt had not been able to tame Wall Street. The Supreme Court didn’t really ratify the SEC as a constitutional body until 1938, and nearly struck it down in 1935 when a conservative Supreme Court made it harder for the SEC to investigate cases.

It took a few years, but New Dealers finally implemented a workable set of securities rules, with the courts agreeing on basic definitions of what was a security. By the 1950s, SEC investigators could raise an eyebrow and change market behavior, and the amount of cheating in finance had dropped dramatically.

Institutional change, in other words, takes time.

he has in mind the younger cohort, Generation Z, usually defined as those born between 1997 and 2012. “When you look at Americans born after 1995,” Mr. Haidt says, “what you find is that they have extraordinarily high rates of anxiety, depression, self-harm, suicide and fragility.” There has “never been a generation this depressed, anxious and fragile.”

He attributes this to the combination of social media and a culture that emphasizes victimhood

Social media is Mr. Haidt’s present obsession. He’s working on two books that address its harmful impact on American society: “Kids in Space: Why Teen Mental Health Is Collapsing” and “Life After Babel: Adapting to a World We Can No Longer Share.

Welcome to cosmic catastrophism

universe began its existence 13.7 billion years ago and has been expanding ever since.

xpansion wasn't always at the same rate.

Although pioneers like Jon Kabat-Zinn, now emeritus professor at the University of Massachusetts Medical Center, began teaching mindfulness meditation as a means of reducing stress as far back as the 1970s, all but a dozen or so of the nearly 100 randomized clinical trials have been published since 2005.

Michael Posner, of the University of Oregon, and Yi-Yuan Tang, of Texas Tech University, used functional M.R.I.’s before and after participants spent a combined 11 hours over two weeks practicing a form of mindfulness meditation developed by Tang. They found that it enhanced the integrity and efficiency of the brain’s white matter, the tissue that connects and protects neurons emanating from the anterior cingulate cortex, a region of particular importance for rational decision-making and effortful problem-solving.

Perhaps that is why mindfulness has proved beneficial to prospective graduate students. In May, the journal Psychological Science published the results of a randomized trial showing that undergraduates instructed to spend a mere 10 minutes a day for two weeks practicing mindfulness made significant improvement on the verbal portion of the Graduate Record Exam — a gain of 16 percentile points. They also significantly increased their working memory capacity, the ability to maintain and manipulate multiple items of attention.

With colleagues at the University of Cambridge, I worked on a web game called urbangems.org. In it, you are shown 10 pairs of urban scenes of London, and for each pair you need to choose which one you consider to be more beautiful, quiet and happy. Based on user votes, one is able to rank all urban scenes by beauty, quiet and happiness. Those scenes have been studied at Yahoo Labs, image processing tools that extract colour histograms. The amount of greenery is associated with all three peaceful qualities: green is often found in scenes considered to be beautiful, quiet and happy. We then ran more sophisticated image analysis tools that extracted patches from our urban scenes and found that red-brick houses and public gardens also make people happy.

On the other hand, cars were the visual elements most strongly associated with sadness. In rich countries, car ownership is becoming unfashionable, and car-sharing and short-term hiring is becoming more popular. Self-driving cars such as those being prototyped by Google will be more common and will be likely to be ordered via the kind of mobile apps similar to the ones we use for ordering taxis nowadays. This will result into optimised traffic flows, fewer cars, and more space for alternative modes of transportation and for people on foot.

Cities will experience transformations similar to those New York has experienced since 2007. During these few years, new pedestrian plazas and hundreds of miles of bike lanes were created in the five boroughs, creating spaces for public art installations and recreation. And it’s proved popular with local businesses too, boosting the local economy in areas where cyclists are freer to travel.
