Humans kill one another so often, for all reasons including none, I wonder how we'd treat a peaceful Alien who visited Earth.

Just saw The Rocky Horror Show at Studio 54, NYC. Was reminded that, in the end, we learn they’re all genderfluid Space Aliens. Until the Pentagon brings out an actual alien, we’re left imagining them. And imagine them we do.

Scientifically literate dogs have always enjoyed my books. But Butters from Los Angeles may have enjoyed "Take Me To Your Leader" a little too much. Or maybe he wanted to eat the evidence of dog aliens found inside.

Educated dogs tend to enjoy my books. Bailey from Boston got an early copy of “Take Me To Your Leader” and especially liked this sentence from Chapter 1: “What if the Alien greets you the way Earth dogs greet each other, and it simply wants to come around and sniff your butt?"

Hmmm. The current price of Platinum futures is around $2,000 per ounce. Gold, around $4,700 per ounce. This throws into question the meaning of a higher-reward Platinum vs Gold credit card.

In the “Pi-Hard” movie trailer (www.youtube.com/watch?v=CNbmoVdirxw), is that the best Alien AI could come up with? A hairy lizard-monster dropped from a vortex in the sky over my City? That scene stretched credulity. Everybody knows Reptiles have no hair.

If current cuts to the Federal Science Budget proposed by the White House are approved by Congress, that will far-and-away be the largest cut to science since the United States began funding it. Republicans & Democrats alike know there’s no surer path to Making America Not-Great.

A @SuperBowl Sunday Fact… In a North-South oriented football Stadium, the rotating Earth forces a kicked field goal to deflect to the right. Depending on the hang-time and distance, it can be as much as 1/3 of an inch.

Wanna see Jupiter in the sky tonight? It’s the bright “star” near the almost-full Moon. Both Jupiter & Earth are currently on the same side of the Sun, so we’re close to each other. Even so, due to light travel time, you see Jupiter only as it once was, 36 mins ago.

Curious fact: The New Years Eve countdown to midnight, second-by-second, is the most precise time-reckoning of a Holiday on the calendar. Meanwhile, the celebration scatters across 24 time zones, requiring a full Earth rotation to complete for everyone.

In case you ever wondered, New Years Day on the Gregorian Calendar is cosmically arbitrary, carrying no Astronomical significance at all. Just Saying. Meanwhile, the dates of Chinese New Year, Lent, Easter, Passover, Rosh Hashanah, Saturnalia, Christmas, & Ramadan, all index to Astronomical events.
