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.

Looking at LPs, CDs, and DVDs with an electron microscope

An evening pause: This video is even more interesting than my title above, in that the guy making it used his electron microscope to make an animation showing what it looks like when a record needle is running through the tracks of a record. Most cool.

And since vinyl appears to actually be making a comeback, I think that even the younger members of my readership will know what a record is.

Hat tip Thomas Biggar.

    Yes– this is (and always has been!) very cool!

    (I still have a 3 foot stack of 78 rpm records from the early 50’s, but no longer have a working 78 rpm speed turntable.)

    Tangential– does anyone remember and/or have any quadrophonic records? It was a short lived format (late 70’s if I recall correctly), wherein they managed to encode 4 channels onto two tracks. They would play normally on any turntable, but if you had the correct equipment (and 4 speakers) you could get a decent 4 channel effect.

    “Vinyl LP sales in the USA hit record numbers during the first half of 2018. Over 7.6 million LPs were sold between 29th December 2017 through the 28th June 2018, a 19.2% increase from the same period in 2017.Vinyl sales now account for over 18% of all physical album sales in the US, a 5% increase from 2017.”

    A tangential, but very cool video:

    I worked for the old CMC stereo chain in Atlanta in the early ’80s. We had a record of the 1812 Overture where they used real cannons for the “This is the cereal that’s shot from guns” part. No electron microscope necessary. One glance and you saw the huge jagged line where the cannons went of. Cheap needles would jump out of the groove in fright.

    As to Quadraphonic, there [mainly] two (incompatible, of course) formats. One was CD-4 (four discrete channels) and the other was SQ (a matrix recording/decoding method)

    One good thing that came out of it was that Dolby Stereo was basically the SQ matrix with the channels turned 45 degrees. (Think of a square turned to the right until it was diamond shaped. What had been the left channel became the center channel and so on)

  • Coolest thing I’ve seen this week.

    eddie–
    Great stuff!
    -If I recall correctly, I have 2-3 discs that utilized the “SQ” methodology.

    Not sure if he mentioned in the video—commercially mass-produced DVD’s and CD’s are physically pressed, in contrast to the disc’s one would create on a PC which are actually “burned” by your disc-writer.

    (These are shellac discs for 78 rpm records. Same methodology was adapted for vinyl. The first “LP” was released in 1948.)

    excuse me…

    Q:
    Who is old enough to remember…when it was super-cool to go check out your friend’s new amplifier, turntable, equalizer, and/or speakers? (or making a cassette copy of a new album?)

  • Max

    Wayne, turntables not so much. But I do have a large collection of eight track tape’s.
    I wonder if there is any videos that show turntables in moving cars… That’s how Motorola got its name.

  • wayne

    Max–
    8-tracks are becoming quite popular with the Hipster-element.

  • Joe

    Wayne, yes more than old enough to remember going to a friends house and ogling their latest turn tables and amplifiers, then I got old and started listening to am radio………..
