  Galactic Ghosts - How Dark...

  Dark matter is one of the greatest mysteries in modern science. Despite being invisible and undetectable by traditional means, it makes up approximately 27% of the universe’s total mass and energy. It does not emit, absorb, or reflect light, making it completely transparent to current observational instruments. However, scientists are certain of its existence due to its gravitational effects on visible matter, radiation, and the large-scale structure of the universe. Its discovery has led to a major shift in our understanding of the cosmos, revealing that most of the universe’s matter remains hidden from our view. 
  The term "dark matter" was first introduced in the early 20th century, but it wasn’t until the 1970s that astronomers began to recognize its significant role in the universe. In 1933, Swiss astronomer Fritz Zwicky observed the motion of galaxies within clusters and noted that the amount of visible matter in these clusters was insufficient to account for their observed gravitational effects. This led him to propose the existence of an unseen form of matter, which he referred to as "dark matter." Over the following decades, similar observations were made by astronomers studying the rotation of individual galaxies. The rotation speeds of galaxies were found to be much higher than what could be explained by the visible matter in the galaxies. This discrepancy suggested that there was additional, unseen matter providing extra gravitational pull, keeping the galaxies intact and preventing them from flying apart. 
  Dark matter does not interact with light or other forms of electromagnetic radiation, which is why it cannot be directly observed. It’s not made up of the usual atoms and particles that constitute the familiar matter we see in everyday life. Instead, it seems to consist of particles that do not interact with electromagnetic forces, which is why they are invisible.

  Gunpowder and the Printing...

  In addition to the wheelbarrow, the seismograph, the waterwheel, deep drilling, suspension bridges, and ship rudders, among countless other life-changing contraptions, the Chinese developed what were later dubbed the “Four Great Inventions of China.” Two of those were gunpowder and printing, which both spread through South Asia and the Middle East before making it to Europe.  
  For a time, gunpowder was a mere curiosity, but its destructive power and military potential would be realized quickly. The first record of a cannon in Europe comes from a manuscript written in 1326, which has an illustration showing an armored man with what looks like a slow match lighting a vase-shaped object. This crude cannon was called a pot de fer in French and vasi in Italian. While medieval engineers developed new types of cannons and explosives capable of destroying walls and castles, others were making the first handguns possible. European sources first mentioned the widespread use of handgonnes, as they were often called, in the late 14th century, precisely the time when gunpowder became cheaper.  
  	The history of printing was for ancient Asia an advancement in culture and communication, but for Europe in the 15th century, it was much more, plunging the continent into a new paradigm and aligning it for the modern world. Its importance is often overlooked, but the timeliness of the printing machine was equivalent to the invention of alphabets in antiquity and ranks up there with the digital revolution and the introduction of the internet. Put simply, it made the Renaissance possible and led to the modernization of Europe. Based on earlier Asian principles, Johannes Gutenberg’s movable type printing press propelled an industry that led to the education of the West and ultimately removed the tight grip of the Vatican from daily European life.

  What the River Knows - Essays...

  Michael Engelhard

  Edward Abbey, who never much liked Alaska, called it "our biggest, buggiest, boggiest state." To others, it has been a cure for despair. When Michael Engelhard moved to Fairbanks more than three decades ago, he was a cheechako, a subarctic tenderfoot. Gathering skills and experiences the hard way, he attained "Sourdough" status while realizing there would always be more to learn, see, and do in the land of midnight sun and auroras. 
   
   
   
  En route, Engelhard suffered frostbite, stubborn yaks, grizzly charges, trophy hunters, cold-water immersion, heartbreak, incontinent raptors, one pesky squirrel, and honeymooners from abroad. He tried to rescue a raven and explored Arctic dunes and a glacier's blue heart, and his own as he mingled with caribou on their epic journeys.
