  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.

  The Titanic. The Britannic. The Olympic. They are some of the most famous ships in history, but for the wrong reasons. 
   
   
   
  The Olympic Class liners were conceived as the largest, grandest ships ever to set sail. Of the three ships built, the first only lost the record for being the largest because she was beaten by the second, and they were both beaten by the third. The class was meant to secure the White Star Line's reputation as the greatest shipping company on earth. Instead, with the loss of both the Titanic and the Britannic in their first year of service, it guaranteed White Star's infamy. 
   
   
   
  This unique book tells the extraordinary story of these three extraordinary ships from the bottom up, starting with their conception and construction (and later their modification) and following their very different careers. Behind the technical details of these magnificent ships lies a tragic human story—not just of the lives lost aboard the Titanic and Britannic, but of the designers pushing the limits beyond what was actually possible, engineers unable to prepare for every twist of fate, and ship owners and crew who truly believed a ship could be unsinkable.

  Life Earth and Politics - Ideas...

  Science, not speculative philosophy, is the only guide, however imperfect, to the nature of existence. Science culture uses and supports science. The social brain experiences free will and needs religious faith. Empathy is a choice based on intuition. We need a better scientific understanding of dogma and chauvinism, and this book explores these issues. It also describes the Crisis of the Anthropocene, described in under a hundred pages, is a wakeup that needs to overcome ignorance and naïve optimism, and reach our deepest emotions. Topics include climate change, biodiversity, pollutants, population, and political causes behind the collapse. This book also presents data from Internationalcomparisons.org that demonstrates that the US is neither advanced nor a democracy and has failed to deal with guns, reproductive rights, taxation, social welfare, fiscal discipline, and other issues. Even with these already significant problems Americans must face, there is even more: Trumpism and Putinism are existential threats to American freedom and democracy. This book presents a framework for others to act in the time of these issues.
