Rap the liberalism of wonderful capitalism: From Verne to dust nanobots

Oh, poetry...
 from verse to universe,

Now it's time to leave the capsule if you dare

This is major Tom to ground control, I'm stepping through the door 

And I'm floating in a most peculiar way

And the stars look very different today

Here am I sitting in a tin can far above the world   (Space Oddity - D.B.)

from multiverse to thingiverse,

flying craft - space tin cans - weaponry spacecraft  

From Robur the Conqueror by Jules Verne (1886)

Given the popularity of space fighters in such mass media shows as Star Wars, Battlestar Galactica, and others, they obviously appeal to people.
The bare idea of combat spacecraft behaving like fighter aircraft is just as silly. In both cases a metaphor is being forced into a situation where it does not work.

In reality, when the Wright brothers invented heavier-than-air flight and Fokker Triplanes started dog-fighting Sopwith Camels, it was totally unlike anything that had occurred before: 

• Biplanes never ever tried to cross the T, 
• and a sea-going battleship had never ever performed a U-turn ( Immelmann turn.)

Top 25 Best Classic Science Fiction Books:

 #18 A case of Conscience

I’ve been a keen science fiction reader most of my life, though less so in recent years as there seems to be less SciFi about. A box of my old books turned up out of a time warp and I’ve decided to re-read them. Here a Blish's book from 1958. "Humanity as government is not shown in a good light in the book, nor is Catholicism. Today, how kindly would we accept a Jesuit priest who wanted to annihilate an alien planet because it is a tool of the devil?"
The genre has been in decline for some time, perhaps because we’ve entered an age of ignorance about science. An age it seems where peer reviewed science can be debated, as if there could be another side.             (Tony- Breadtag sagas)

       The iffy years .....

IF any learning is self-learning,perhaps... in the (near)future, any production will turn into self-production, replicant machines all over.

TASK. Listen and take notes.... (up to 06:25)

RepRap is humanity's first general-purpose self-replicating manufacturing machine.
RepRap takes the form of a free desktop 3D printer. Since many parts of RepRap are made from plastic and RepRap prints those parts, RepRap self-replicates by making a kit of itself - a kit that takes you to a thingiverse!  thump,thump Aldous Huxley's BNW-1931! It also means that - if you've got a RepRap - you can print another RepRap for a friend...

CODA:

From this and that:  nanobots,  

there are 4.184e12 joules in a kiloton and 4.184e15 joules in a megaton. So simply:

E_kt = M * 42961.6

E_mt = M * 43.0

where:

• E_kt = total annihilation energy (kilotons)
• E_mt = total annihilation energy (megatons)
• M = mass of antimatter (kilograms) Please note that M is the mass of antimatter, NOT the mass of the matter + the antimatter.

If you are interested, 42961.6 is from (9.0e16 * 2) / 4.184e12 where 9.0e16 = c², 4.184e12 = joules in a kiloton, 2 = 1 unit of matter + 1 unit of antimatter.
