How Monet’s paintings changed the way we see London

Between 1899 and 1901, legendary French Impressionist painter Claude Monet produced over 100 paintings of London consistently shrouded in fog. Art historians claim this series left a permanent mark on how we perceive the capital city, inevitably layered in obscuring and dramatic mist. See some of the paintings and read more here.

'Wanderer Above the Sea of Fog' is an iconic romantic artwork

Caspar David Friedrich’s painting portrays man’s fascination with the natural world and emphasizes his smallness in the midst of its grandeur, epitomizing Edmund Burke's concept of "the sublime."

Vincent Van Gogh's 'The Starry Night' accurately depicts turbulent flow

Analysis of the swirling patterns in the painting found an alignment with the mathematics used to describe turbulence, despite Van Gogh's unfamiliarity with the science. The depiction may indicate he possessed an uncanny ability to capture nature's details.

The ideas of Einstein and Freud combined in 'The Persistence of Memory'

The Persistence of Memory was painted on a canvas roughly the size of a sheet of paper, depicting a desolate landscape with melting clocks, ants, and a distorted figure. The piece incorporates Freud and Einstein's ideas, resulting in a haunting composition symbolizing time's fluidity and Dalí's personal anxieties.

Peter Brueghel's 'Hunters in the Snow' depicts winter beauty and hardship

The Dutch painter and printmaker is known for centering ordinary subjects at a time when protestant iconoclasts protested religious images and reduced the Church's role as an arts patron. The famous painting is often viewed as a cozy winter scene, but reveals the difficulties of harsh winters during the Little Ice Age in Europe.

Some theorize that horror's artifice turns fear into enjoyment

The “excitation transfer theory” suggests that the unpleasant feelings a jump scare might elicit (like shortness of breath) are quickly relieved when the audience member remembers what they’re witnessing is fake.

Scientists used mass spectrometry to determine the materials in a 1690 painting

Previously used to map the distribution of molecules on biological tissue samples, researchers combined the technique with machine learning to uncover six layers of pigments, binders, and a thin gold leaf layer within *The Marriage of the Virgin*, from a collection in the Metropolitan Museum of Art. The technique may help identify and track artists' material use to learn about pieces of unknown provenance. (Some readers may experience a paywall.)

The life of Edward Lorenz, who originally used a seagull in his 'butterfly effect' metaphor

By accidentally finding that rounding one variable to its third decimal place and re-running a weather simulation produced a drastically different two-month forecast, the American mathematician established the field of chaos theory. His paper—"Predictability: Does the Flap of a Butterfly's Wings in Brazil Set off a Tornado in Texas?"—introduced the well-known metaphor for the behavior of chaotic systems. (Some readers may experience a paywall.)

The conditions needed for cloud iridescence, or rainbow clouds

The relatively rare phenomenon occurs when sunlight scatters off tiny water droplets or ice crystals in thin, newly-forming or semi-transparent clouds, such as altocumulus, cirrocumulus, lenticular, and cirrus varieties. This effect is similar to what is seen in soap bubbles and mother-of-pearl shells and produces pastel-like colors.

Scientists have tested atmospheric models by firing rockets into the aurora borealis

Functioning like components of a CT scan, the missiles transmit signals that can be used to identify charged particles and electromagnetic currents in slices. The slices are then combined to construct a computer-based model of Earth's atmospheric structure, which is used to compare the accuracy of physics-based models.

Chaos theory—informally known as the butterfly effect—is the reason why weather forecasts are presented with probabilities rather than certainties.

Why some people say the moon is made of cheese

Mental Floss digs into the history behind the fable, which dates back as far as the 1500s, when it was mentioned in "The Proverbs of John Heywood." Even NASA has gotten in on the joke, tweeting a (supposedly) doctored photograph showing the moon's expiration date.

An in-depth account of the image of 'The Falling Man' whose final seconds capture the visceral horrors of 9/11

Do you remember the photograph above? In the US, people have taken pains to banish it from the record of Sept. 11, 2001. Here's a detailed account of the story behind it, the search for the man pictured in it, and its impact on those who lived through the tragic day.

The history of germ theory, which explains that illnesses are caused by microorganisms

For centuries, the miasma theory, which held that illnesses were caused by clouds of "bad air" produced by decaying organic matter, was the accepted explanation for the spread of disease. The development of microscopes and the subsequent technology to isolate bacteria and test disease spread in mice greatly contributed to contagionists overturning miasmatists.

What types of extreme weather can be attributed to climate change?

For decades, it was impossible to say that a specific weather event was caused, or even made worse, by climate change. But advanced research methods are changing that.

Photographer William Mumler claimed to photograph ghosts

Spirit photographer William Mumler rose to prominence during the spiritualist movement in the United States. His photographs engrossed and bewildered both believers and nonbelievers. Though Mumler was tried for fraud, his methods were never discovered.

Historians theorize Vincent Van Gogh suffered from Ménière's disease or epilepsy

A century after researchers suggested he suffered from epilepsy, some researchers in the 1990s began to support an alternate diagnosis: Ménière's disease, since he had suffered from severe, repeated attacks of disabling vertigo. Still, some researchers remain skeptical of the Ménière's diagnosis. One posits that Van Gogh had temporal epilepsy complicated by his absinthe consumption.

How Bauhaus resonated in Norway

The Bauhaus style may have originated in Germany, but it had a major impact in Norway. This history unpacks the work of Marianne Brandt, Thorbjørn Lie-Jørgensen, Ola Mørk Sandvik, Hans Mollø-Christensen, and other Norwegian designers and architects

Explaining the icy mystery of the Dyatlov Pass deaths

A decades-old mystery from Soviet Russia could be explained by studying the science of snow. After nine students died on a hiking trip in the Ural Mountains, Soviet investigators found six had perished from hypothermia while three others died from blunt force trauma. The mystery confounded officials for years, and rumors of yeti attacks and similar theories abounded until researchers proposed a new potential culprit: an avalanche.

Scientists can determine Earth's past climate conditions by analyzing air trapped in microscopic bubbles within ice cores—columns of compressed snow layers that build up over hundreds of thousands of years.

Georgia O'Keeffe's flower paintings are often assumed to be sexual, though the artist claimed she was simply interested in highlighting the beauty of flowers that most people neglect

All hurricanes have a central eye where no extreme weather phenomena take place

When standing in the eye of a hurricane, you're likely to experience sunny, cloudless skies surrounded by a wall of intense winds and thunderstorms. The physics behind this formation is the same as what causes water to spiral around a hollow cone as it goes down a drain.

In 1820, a sperm whale sank a ship and inspired 'Moby-Dick'

The Essex's crew hoped to capture sperm oil, a lucrative material found in the heads of sperm whales. However, a whale charged and crashed into the ship. Survivors of the attack drifted at sea for months, and many experienced starvation, dehydration, and cannibalism. The ordeal inspired author Herman Melville.

Alfred Hitchcock influenced thriller filmmaker M. Night Shyamalan

There may be no more obvious heir to Alfred Hitchcock’s throne than M. Night Shyamalan, the director known for suspenseful films like “The Sixth Sense,” “Signs,” and “The Village.” It should come as no surprise that Shyamalan says he’s a big fan of “the Master of Suspense,” going so far as to cite Hitchcock’s “Rebecca” as a major influence, one he called “epic and haunting.”

'Ram’s Head, White Hollyhock—Hills' marked a shift in O’Keeffe’s life and work

After a severe drought in the 1930s killed many animals near her home, O’Keeffe started collecting and painting their skulls. Her new style was interpreted as surreal and even macabre by many, presenting a shocking turn from her lighthearted flower portraits.
