So what did Columbus do this made him well-known? Well, not all that much to be trustworthy. For starters, he was a horrible navigator. He wasn’t looking for what we now name North America or South America. He was charting a waterway path to India and failed miserably! On prime of that he introduced illness to the natives already living within the Americas. He also enslaved natives, pressured them to just accept Christianity, and killed many. Columbus did not even discover America as he is often giving credit for! That honor goes to Leif Eriksson 500 years earlier!!!

Welcome to 2017! I hope you had a fun and happy time this vacation season. For these of us who care in regards to the environmental future of this planet, the latter a part of 2016 was a troublesome capsule to swallow. The President-elect has publicly acknowledged climate change is a hoax perpetrated by the Chinese and the United States House of Representatives has openly attacked scientists studying climate change. In late 2016 the U.S. House Science and Technology committee has tweeted anti-climate change propaganda that could be a promotion of outright lies.

I admit I have not completed the trilogy yet In truth, I have not even completed the first book, however up to now I’ve actually enjoyed it. It starts with the invasion of Earth by an alien race, the Illyri. The Illyri take over, however don’t wipe out humanity nor do they enslave people. Humans continue to stay facet by facet with the Illyri. I’m about one hundred pages in and to this point it’s not so easy to determine who is correct and who’s fallacious in a few of the things that have taken place. It’s a different fashion of science fiction than I sometimes read so I’m very intrigued as to how the book will end.

So why 1 / 4 moon? Nowhere within the dialogue above does 25% come into play! A quarter moon has nothing to do with seeing 25% of the moon’s surface illuminated or the moon’s floor being 25% illuminated. The moon’s floor is ALWAYS 50% illuminated. The phrase ‘quarter moon’ has to do with the place in the lunar cycle the moon is. The begin of a lunar cycle occurs when the moon is in its new phase. Next comes waxing crescent, first quarter, waxing gibbous, full, waning gibbous, third quarter, and at last waning crescent before heading back to a new moon. A first quarter is one quarter of the best way by way of this cycle and a third quarter is three quartesr of the way in which through the cycle. This is where the quarter phases come from, not the % noticed to be illuminated or the % of precise illumination.
