The eruption of the Tonga volcano in January has been confirmed as the biggest explosion ever recorded in the atmosphere; being far more powerful than any atom bomb test. 🔗 Link
Dozens of iconic weedy seadragons have washed up on beaches across NSW, Australia. Some combination of bad weather, pollutants, and big surf is to blame. 🔗 Link
An ancient tooth suggests Denisovan humans lived throughout a much broader geographic range than we thought. A fossilized tooth that’s 164,000-131,000 years old has been unearthed in a cave in northern Laos that might have belonged to a young Denisovan girl. 🔗 Link

What distant and different beings in the various mansions of the universe are contemplating the same [stars] at the same moment!
Henry David Thoreau, Walden
The improvements of ages have had but little influence on the essential laws of man’s existence.
Henry David Thoreau, Walden
To be a philosopher is not merely to have subtle thoughts, nor even to found a school, but so to love wisdom as to live according to its dictates, a life of simplicity, independence, magnanimity, and trust. It is to solve some of the problems of life, not only theoretically, but practically.
Henry David Thoreau, Walden
Leading physicist Lee Smolin has estimated that from its inception, had the primary forces and physical attributes of our universe varied by more than an unimaginably precise one part in 10²⁷ —that’s one part in a thousand trillion trillion!—our complex universe of chemistry, galaxies, and biological life could not have evolved.
The exquisite harmony of these cosmic relationships includes the fundamental ratios between the electrical and nuclear forces that bind atoms and molecules and the vastly weaker force of gravity. Their precisely balanced energies and the exact yet varied nature of their interrelationships, from the moment our universe was born, have enabled the formation and interaction of chemical elements; the birth of stars, galaxies, and planets; and the evolution of biological organisms and ecologies. Without their incredible level of finely tuned precision from the very beginning of space time, the complex universe we experience could not exist.
