  Mesoamerican Astronomy: The...

  For the Maya, astronomy was not a purely scientific pursuit but intimately linked to religious, mythological, and ideological elements that were of the highest importance. The celestial realm held a sacred nature, as did the many gods and goddesses that dwelt there, so for all Mesoamerican cultures, astronomy was a fundamental part of their everyday lives. Thus, astronomy was present in their calendars, religion, and even agriculture, and in close relation to astronomy, the concept of time was also an essential part of their worldview.  
  The Aztec recorded many of the astronomical events they observed in codices and hieroglyphic inscriptions, but the main evidence of their deep astronomical knowledge comes from their calendar system. This information was then used to plan the orientation of buildings and ceremonial centers, which were aligned to sunrises or sunsets corresponding to special dates, such as solstices or equinoxes. Observational calendars were also used to schedule agricultural activities, as well as rituals, festivals, and celebrations. 
  Though the Spanish physically conquered them in quick fashion, the culture and legacy of the Inca Empire has continued to endure throughout the centuries in both Europe and South America, due in no small part to the fact they were one of the most advanced and sophisticated cultures on the continent. The sun was the main element present in the Inca worldview, so Inti, the sun god, was worshipped above all others and, even though the different parts of the empire were allowed to practice their individual beliefs, they were encouraged to venerate the sun. The connection with the sun even extended to their kings since they were considered to be the sons of the sun. Naturally, this meant astronomy was a key component of the Incas’ beliefs, and in addition to the sun, the Inca observed the moon, stars, constellations, and some planets, all of which became integral parts of their cosmology.

  Ditch the devices and bring back the magic of being a kid    
   Screens are everywhere. Children spend an average of 7.5 hours on digital devices every day with profoundly negative consequences. While some tech may “amplify” real life experience (online music lessons or Zoom calls with faraway family, for example), the vast majority “amputates” by limiting physical activity, creating anxiety, or damaging self-esteem.  Childhood Unplugged  takes a bold approach to creating healthy boundaries around the use of digital media, suggesting kids should be offline for the majority of their time.   
   Drawing on her own family’s experience, plus interviews with digital minimalists, educators, and child development experts, author Katherine Martinko presents:    Meticulously researched analysis of the impacts of excessive screen time on children's physical, neurological, emotional, and social development   Specific pathways to reduced screen exposure, naturally leading to more time spent outdoors, increased confidence and empathy, more creative and active play, and other benefits   Inspiration for caregivers overwhelmed by the thought of severing ties with the digital babysitter   Age-appropriate advice for fundamental change, with specific sections for babies and toddlers, school-aged children, and adolescents.    
   Taking a calming, nonjudgmental approach,  Childhood Unplugged  is a lifeline for parents, caregivers, educators, and anyone who questions the role of digital media and yearns for the young people in their life to experience the profound beauty and magic of childhood.

  Atomic Days - The Untold Story...

  Once home to the United States's largest plutonium production site, the Hanford Nuclear Reservation in Washington State is laced with 56 million gallons of radioactive waste. The threat of an explosive accident at Hanford is all too real—an event that could be more catastrophic than Chernobyl. 
   
    
   
  The EPA designated Hanford the most toxic place in America; it is also the most expensive environmental clean-up job the world has ever seen, with a $677 billion price tag that keeps growing. Huge underground tanks, well past their life expectancy and full of boiling radioactive gunk, are leaking, infecting groundwater supplies and threatening the Columbia River. 
   
   
   
  Whistleblowers are now speaking out, hoping their pleas can help bring attention to the dire situation at Hanford. Aside from a few feisty community groups and handful of Indigenous activists, there is very little public scrutiny of the clean-up process, which is managed by the Department of Energy and carried out by contractors with shoddy track records, like Bechtel. In the context of renewed support for atomic power as a means of combating climate change, Atomic Days provides a much-needed refutation of the myths of nuclear technology—from weapons to electricity—and shines a spotlight on the ravages of Hanford and its threat to communities, workers, and the global environment.
