What makes Elon Musk and Carl Sagan worlds apart

What makes Elon Musk and Carl Sagan worlds apart

Shannon Stirone writes: There’s no place like home—unless you’re Elon Musk. A prototype of SpaceX’s Starship, which may someday send humans to Mars, is, according to Musk, likely to launch soon, possibly within the coming days. But what motivates Musk? Why bother with Mars? A video clip from an interview Musk gave in 2019 seems to sum up Musk’s vision—and everything that’s wrong with it. In the video, Musk is seen reading a passage from Carl Sagan’s book Pale Blue…

The unified cosmic vision of Alexander von Humboldt

The unified cosmic vision of Alexander von Humboldt

Algis Valiunas writes: The presiding scientific genius of the Romantic age, when science had not yet been dispersed into specialties that rarely connect with one another, Alexander von Humboldt wanted to know everything, and came closer than any of his contemporaries to doing so. Except for Aristotle, no scientist before or since this German polymath can boast an intellect as universal in reach as his and as influential for the salient work of his time. His neglect today is unfortunate…

Human-made stuff now outweighs every living thing on Earth

Human-made stuff now outweighs every living thing on Earth

ScienceAlert reports: All of the Amazon’s splendid greenery. Every fish in the Pacific. Every microbe underfoot. Every elephant on the plains, every flower, fungus, and fruit-fly in the fields, no longer outweighs the sheer amount of stuff humans have made. Estimates on the total mass of human-made material suggest 2020 is the year we overtake the combined dry weight of every living thing on Earth. Go back to a time before humans first took to ploughing fields and tending livestock,…

Signs of recent volcanic eruption on Mars hint at habitats for life

Signs of recent volcanic eruption on Mars hint at habitats for life

The New York Times reports: Mars was once home to seas and oceans, and perhaps even life. But our neighboring world has long since dried up and its atmosphere has been blown away, while most activity beneath its surface has long ceased. It’s a dead planet. Or is it? Previous research has hinted at volcanic eruptions on Mars 2.5 million years ago. But a new paper suggests an eruption occurred as recently as 53,000 years ago in a region called…

Pope Francis: A crisis reveals what is in our hearts

Pope Francis: A crisis reveals what is in our hearts

Pope Francis writes: In this past year of change, my mind and heart have overflowed with people. People I think of and pray for, and sometimes cry with, people with names and faces, people who died without saying goodbye to those they loved, families in difficulty, even going hungry, because there’s no work. Sometimes, when you think globally, you can be paralyzed: There are so many places of apparently ceaseless conflict; there’s so much suffering and need. I find it…

‘Pristine’ extraterrestrial organic compounds found on meteorite may shed light on origin of life on Earth

‘Pristine’ extraterrestrial organic compounds found on meteorite may shed light on origin of life on Earth

Vice reports: On a dark winter night in 2018, hundreds of people across the Great Lakes region witnessed a radiant meteor brighten the skies. Mere days after the fireball streaked overhead on that night in January, scientists were able to track down precious pieces of the ancient space rock using weather radar reports. The scattered remnants of the object, known as the Hamburg meteorite, contain a “high diversity” of extraterrestrial organic compounds that are preserved “in a pristine condition,” according…

Migratory bird flies non-stop over 7,500 miles from Alaska to New Zealand

Migratory bird flies non-stop over 7,500 miles from Alaska to New Zealand

The Guardian reports: A bird said to have the aerodynamic build of a “jet fighter” has been tracked flying more than 12,000km (7,500 miles) from Alaska to New Zealand, setting a new world record for avian non-stop flight. The bar-tailed godwit set off from south-west Alaska on 16 September and arrived in a bay near Auckland 11 days later, having flown at speeds of up to 55mph. The male bird, known as 4BBRW in reference to the blue, blue, red…

The molecular biologist, Jacques Monod, saw chance as one of the ‘secrets of life’

The molecular biologist, Jacques Monod, saw chance as one of the ‘secrets of life’

Sean B. Carroll writes: Jacques Monod arrived in Paris to some dreadful news. On June 5, 1944, four years into the German occupation of France during World War II, he was supposed to meet with fellow leaders in the French Resistance when his assistant, Geneviève Noufflard, told him that several commanders within the greater Paris region had just been caught by the Gestapo. Monod was pretty sure that at least one of those arrested knew about the rendezvous he was…

The value of uncertainty

The value of uncertainty

Mark Miller et al write: Understanding our own relationship with uncertainty has never been more important, for we live in unusually challenging times. Climate change, COVID-19 and the new order of surveillance capitalism make it feel as if we are entering a new age of global volatility. Where once for many in the West there were just pockets of instability (deep unpredictability) in a sea of reliability – albeit sometimes in disagreeable structures and expectations – it lately seems as…

Physics and information theory give a glimpse of life’s origins

Physics and information theory give a glimpse of life’s origins

Natalie Elliot writes: How did life originate? Scientists have been studying the question for decades, and they’ve developed ingenious methods to try to find out. They’ve even enlisted biology’s most powerful theory, Darwinian evolution, in the search. But they still don’t have a complete answer. What they have hit is the world’s most theoretically fertile dead end. When scientists look for life’s origins, they usually work in one of two directions. They work backwards in time through the record of…

For Schopenhauer, happiness is a state of semi-satisfaction

For Schopenhauer, happiness is a state of semi-satisfaction

David Bather Woods writes: On 13 December 1807, in fashionable Weimar, Johanna Schopenhauer picked up her pen and wrote to her 19-year-old son Arthur: ‘It is necessary for my happiness to know that you are happy, but not to be a witness to it.’ Two years earlier, in Hamburg, Johanna’s husband Heinrich Floris had been discovered dead in the canal behind their family compound. It is possible that he slipped and fell, but Arthur suspected that his father jumped out…

The return of existentialism

The return of existentialism

Carmen Lea Dege writes: Existentialist ideas have seen a remarkable comeback during the COVID-19 pandemic, from Albert Camus’s frequently invoked novel The Plague, Friedrich Nietzsche’s turn to tragedy, and Simone de Beauvoir’s and Jean-Paul Sartre’s critique of bad faith, to Giorgio Agamben’s Carl Schmitt–inspired musings about the state of emergency and what Michel de Montaigne, Martin Heidegger, and Blaise Pascal can teach us about facing death. The thread running through all these appeals to existentialism is a sensitivity to human…

Why a Roman philosopher’s views on the fear of death matter as coronavirus spreads

Why a Roman philosopher’s views on the fear of death matter as coronavirus spreads

Lucretius Carus. Internet Archive Book Images/Flickr By Thomas Nail, University of Denver With the global spread of the new coronavirus, fears about illness and death weigh heavily on the minds of many. Such fears can often result in a disregard for the welfare of others. All over the world, for example, essential items such as toilet paper and hand sanitizer have been sold out, with many people stockpiling them. A first-century B.C. Roman poet and philosopher, Lucretius was worried that…

The consciousness of rats has ethical implications for humans

The consciousness of rats has ethical implications for humans

Kristin Andrews and Susana Monsó write: In the late 1990s, Jaak Panksepp, the father of affective neuroscience, discovered that rats laugh. This fact had remained hidden because rats laugh in ultrasonic chirps that we can’t hear. It was only when Brian Knutson, a member of Panksepp’s lab, started to monitor their vocalisations during social play that he realised there was something that appeared unexpectedly similar to human laughter. Panksepp and his team began to systematically study this phenomenon by tickling…

The demise of bees will lead to ours too unless we change the way we grow food

The demise of bees will lead to ours too unless we change the way we grow food

Alison Benjamin writes: The oldest love affair in history is between the bee and the flower. It began more than 100m years ago, when nature devised a more efficient way than winds for plants to procreate. About 80% of plant species now use animals or insects to carry pollen grains from the male part of the plant to the female part. The plants developed flowers. Their perfumed scent, colourful displays and sweet nectar are all designed to woo pollinators. Over…
