Please alert the authorities if your eclipse tonight looks like this:

Dear Everyone in the Earth’s Eastern Hemisphere: If you can see the Moon at all you're witnessing a total lunar eclipse over the next few hours. The Full Moon is passing in & out of Earth’s conical shadow in space. This event is boring & resembles the Moon going through phases.

Early Riser, might you be? Want a spectacle for free? Before sunrise you will see Two bright stars — planets they be. The brightest one is Venus. Outshining Jupiter’s light. Catch both before they’re consumed By all of morning twilight.

How I Think About Climate Change


July 4, 1776: Wondering whether the USA is the only country to celebrate its independence on the anniversary of simply declaring it, rather than on the anniversary of winning it. In our case, the British surrender at Yorktown, Virginia: October 19, 1781. If so, that’s badass.

Nothing wrong with expecting people to pick themselves up by their bootstraps, until you realize that some people have no boots.

.@corbintrent FYI (1/2)

During Q&A at a recent public talk I gave in southern Georgia, a gentlemen in VIP seating self-identified as a Nerd Redneck. Told him about “Blerds” (Black Nerds) and that he needed a name for his people. We agreed on “Nerdnecks.” Many Nerdnecks are also fans of @StarTalkRadio.

Time for Nerdnecks to rise up & spread objective truths to all irrational places of the world. Nerdnecks surely include Redneck & Hillbilly engineers: hillbillyengineering.us youtube.com/@redneckengine… Do Nerdnecks argue with crazy relatives at holiday dinners as other Nerds do?



Every machine in a Hospital that diagnoses your body without cutting you open is based on a principle of Physics, discovered by a Physicist who had no interest in Medicine. If you think the world doesn’t need Basic Science, or that somehow Science has failed you, think again.
