Conscious Choice cover

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.


“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.

Euler’s Disk

An evening pause: Something for all those new home schoolers, and their parents, to puzzle over and use to learn something worthwhile and real.

Note also how the concave mirror eventually forces the disk into the center of the mirror.

    a sample….

    MIT Physics 8.01x
    “Lecture 6 – Newton’s Laws”
    Walter Lewin

    “Watch all my 94 MIT course lectures. Start with 8.01, then 8.02, then 8.03. Do all the homework and take all my exams. Homework and exams are posted below the video thumbnails. I guarantee you, that you will then not fail the Physics portion of any exam.”

    Now I wonder if this has a thermodynamic counterpart with “anti-freezing:”

    “When vibrations increase on cooling: Anti-freezing observed”

    From Aug 4 2021 at Helmholtz Association… nickel oxide.

    The term anti-freezing made me think back to Egon Bach’s ideas of work and “anti-work” when it came to “geometeors” as Olkhovatov thought Tunguska was..
