Crowd Vortices

The Feast of San Fermín in Pamplona, Spain draws crowds of thousands. Scientists recently published an analysis of the crowd motion in these dense gatherings. The team filmed the crowds at the festival from balconies overlooking the plaza in 2019, 2022, 2023, and 2024. Analyzing the footage, they discovered that at crowd densities above 4 people per square meter, the crowd begins to move in almost imperceptible eddies.

“You look at trees and called them ‘trees,’ and probably you do not think twice about the word. You call a star a ‘star,’ and think nothing more of it. But you must remember that these words, ‘tree,’ ‘star,’ were (in their original forms) names given to these objects by people with very different views from yours. To you, a tree is simply a vegetable organism, and a star simply a ball of inanimate matter moving along a mathematical course. But the first men to talk of ‘trees’ and ‘stars’ saw things very differently. To them, the world was alive with mythological beings. They saw the stars as living silver, bursting into flame in answer to the eternal music. They saw the sky as a jeweled tent, and the earth as the womb whence all living things have come. To them, the whole of creation was ‘myth-woven and elf patterned’.”

— J.R.R. Tolkien, from ‘Mythopoeia’

whatever this is that I am
a little wisp of soul carrying a corpse
a brief instant is all that is lost
a split second in eternity
Everthing fades so quickly, turns into legend, and soon oblivion covers it // a minute after death
Remember, nothing belongs to you but your flesh and blood - and nothing else is under your control.

Meditations by Marcus Aurelius

The Books I'm Reading At The Moment.

Meditations by Marcus Aurelius - I love this book. It puts you in the perspective of the time and space you occupy, I found a lot of my own thinking and feelings within the pages of this book. A guy born in AD 121 has very clear view on life that is still relevant today.

The Books I'm Reading At The Moment.

Great Adaptations by Kenneth Catania - A professor of biological sciences takes you on a journey with him while he studies various animals adaptive abilities. Star nosed moles, electric eels, tentacled snakes... Very interesting insight in how these creatures evolved and adapted.

The Books I'm Reading At The Moment.

What we cannot know by Marcus du Sautoy - Explains concepts from the ground up, I like the illustrations that accompany the text and practical examples. Lays foundations to the known and wonders into the future of research and the possibilities that come with it as well as limitations. Covering themes from quantum physics and cosmology to sensory perception and neuroscience.

The Books I'm Reading At The Moment.

Labyrinths of reason by William Poundstone - "Blue sky, sunshine, deja vu glazed with dread." How do you know this isn't all a dream? Is anything certain? Ontology, logic, mathematics, deduction, epistemology, memory formation, paradoxes and puzzles.

The Books I'm Reading At The Moment.

A brain for numbers by Andreas Nieder - Humans' understanding of numbers is intuitive. How are infants able to perceive numbers even before they learn the words for them? How do our brains process numbers? Can animals count? He shows how it is an adaptive ability and that plenty of animals have the number sense too. There is a variety of research and supporting evidence mentioned which I really like.
