But many of the seeds never took, apparently having died for lack of fertile soil. Quote Baal wrote: If only Archimedes had the zero (sigh).

I got my information from the best lecture, not Nova or Discovery. And I referenced the papers of the best discovery for those who want to explore the details for themselves. The point here is that the Antikythera Device, attributable perhaps to Archimedes or perhaps to a collaboration among Euclid, Apollonius, and Archimedes, was not a singular creation. It was obviously the result of a long development and could not have existed in isolation. Yet, where are the other evidences? We know from references about coin-operated prayer machines, and the steam engine of Heron. But we have not much else... I point also to a reference that the First Citizen ("emperor") Claudius wrote a multivolume history of the Etruscans. He may have included a grammar of the language. All of that, too, is lost, and it came from the center of power of the time. I am not one of the doomsayers here an in O-land who seem to look forward to the coming collapse of civilization.

That said, however, if you consider the Bronze Age Collapse, and the decline of Rome, it is clear that all of this is very fragile. It deserves respect and protection.

Every civilized society - and many other cultures - has "merchants" but capitalism only came from the confluence of Renaissance and the invention of statistics. The Romans of Archimedes' time had merchants. But their society valued conquest more.

The book is due here Monday.) You are aware, I assume, that what we know of the Device is based on reverse engineering. Using the most advanced scanning technology the innards of the device were made visible. The scholars studying the device could see which gears connect to which gears and how many teeth were on each will. By working out the gear ratios they were able to guess that the device did astronomical calculations. Perhaps it took a team to make the Device in the first place. It surely took a very talented team to come up with a hypothesis based reconstruction of the Device. In a way, the reconstruction of the Device invoked one of Aristotle's Four Causes. The most subtle of the cause, the Final Cause says a thing exists in order to achieve an end, purpose or goal. The scholars studying the A.K. Device concluded that it was a hand carried astronomical simulator and astronomical calendar. Its purpose was to imitate the observed positions of observable astronomical bodies and moon phases. Once the scholars knew or postulated what the device -was for- they were able to fill in gaps in their knowledge of the total device, because not all the pieces survived corrosion. So final cause was bounded back to formal cause and material cause a bounced forward for rechecking. Cool! Score one for the Philosopher and the A.K. Device team. If the Greek mathematicians had the zero, then their successors would have come up with the mathematics of motion much sooner. Think of having differential equations one thousand years sooner. Advances in physics were driven by both new facts discovered by observation and by knowing the underlying mathematical symmetries of cosmos. O.K., I was exaggerating a bit about the Star Ships but I am certain we would have had heat engines and flying machines much sooner than we actually did. It is almost certain that optics would have been advanced with better mathematics, which in term means we would have had telescopes and microscopes sooner. As it was Archimedes did come up with something very close to integral calculus (look uj Archimedes Codex). But his math did not "catch on". He did not establish a school. There is a case of the Great Man not achieving his full potential because the society around him was not ready for it. Your observations of the rise of capitalism out of mercantilism appear to be on the mark. For one Great Man to succeed a lot of little pieces and a lot of smaller men have to be ready to carry the matter through. In a sense, the times have to be right and ripe for the advance.

syrakusos 1 Report post Posted July 28, 2017 How the Martians Discovered Algebra by Roger E. Bissell arrived yesterday. It is nicely done. CreateSpace did a good job. I ordered the book on July 18, 2017, and got a programmed response to that. I received a confirmation on July 22 with a promise of July 31 arrival. The book arrived via UPS on July 26. Just reading a random page for now, it reminds me of George Boole. We are taught to think of syllogisms as reductions. Boole presented his algebra as a way to expand statements. So, too, does Bissell (as far as I have read) expansively explain that 0 + 5 is not "five added to zero," but starting with no action, you begin with the existence of five items. (More later...)

The ancient Egyptian stone cutters long before Pythagoras and his friends used a knotted rope with equally spaced knots in the pattern 3 knots, 4 knots, 5 knots to "square" off the blocks of marble and granite that they quarried. 3,4,5 is the simplest Pythagorean integer triple.

syrakusos 1 Report post Posted August 8, 2017 I woke up at 2:00 AM and have to be in the office early anyway... so, I worked the Bissell Algorithm for Pythagorean Triples and it did not come out right for me. I want to check my arithmetic, of course. In the mean time, I am disappointed that no one else here bought the book. Let me tell you a story... When I was about 8 or 10, one summer, a neighbor kid from the next block that some of the other kids knew had family over from out of town. They went to an Indians game. The out of town cousin caught a foul ball that was hit into the stands. He brought to to show us. No one believed him. Many years later, it occurred to me that the problem was the Dead End Kids. There was an implicit sense of life assumption that nothing great would happen to any of us. We all knew the Abraham Lincoln myths about America. Everyone's family was there seeking something better. But this was far deeper than that. And I have seen this elsewhere in life and it is operative here. Major Premise: I am an idiot. Minor Premise: Bissell hangs out with me. Conclusion: Therefore, Bissell is an idiot. I am not going to stomp off mad and never come back, just to come back anyway, but I can discuss this with Roger offline.

Not only is the Roman numeral system clunky for doing math, it's lame for even making a numbered list.

Finally, I saw it way at the bottom of the folder's list, underneath files whose name started with S and T and U. Yikes. Then I realized the first four were only together because the computer interpreted I, II, III, and IV as starting with the *letter* I. Double yikes.

There is a metaphysical interpretation Roger might like. But I wouldn't regard 0 degrees on a thermometer nor a pH=0 (very acidic) as "nothingness." zero is NOT nothingness. It is a definite thing with algebraic properties. 1. 0 + x = x + 0 = x for all x. 2. 0 X a = a X 0 = 0 for all a. 3. given x there exists -x such that x + (-x) = 0. 0 is too busy to be nothing. 0 also hold a column open to receive a carried digit. 0 is how we tell 220 and 22 and 202 apart. That is the trick the Babylonian "primitives" had that the Greeks did not. The closest 0 come to being "nothing" is being the cardinal number of the empty set. In a binary circuit 0 is low voltage and 1 is high voltage. In a spintronic circuit (the kind of circuit the quantum computers will have) 0 is spin-down and 1 is spin--up. These are the quantified values of angular momentum for Fermions. Only a philosopher or a jester could confuse 0 with Nothing. Share this post Link to post Share on other sites

Roger Bissell 2 Report post Posted August 16, 2017 On 8/9/2017 at 1:53 PM, BaalChatzaf said: zero is NOT nothingness. It is a definite thing with algebraic properties. This is a false alternative. Zero is not absolute nothingness. But that doesn't mean it is something. It is the absence of something. Not the absence of anything whatsoever (that would be absolute nothingness), but the absence of something in particular. The phrase "zero apples" does not mean that there is some number of apples, and that number is zero. It means that there are not any apples, that any attempt to count the apples does not produce any results, and by convention, we say that we have "counted zero apples," when in fact we have not counted any apples. All of the so-called "algebraic properties" of zero are actually just the results of attempting to perform calculations in the absence of any quantity that one would normally be able to perform such calculations. Some say this is "a difference without a difference." By the same token, quantum mechanical equations produce the same results regardless of whether one adopts the Copenhagen interpretation or a more realistic interpretation. And perhaps there are not now any reasons for preferring one interpretation of the metaphysics of quantum mechanics or the metaphysics of zero over another. But I'm confident that there are reasons for preferring a realistic interpretation over one that reifies non-existence, even the relative or particular non-existence captured in how we use the concept of "zero" in mathematics. Even now, we have recently seen some Danish students who have found a method of measuring the position and momentum of subatomic particles, and who have thus proved that Heisenberg's Uncertainty Principle is ONLY the claim of a methodological limitation on simultaneous measurement of position and momentum of particles, and not a metaphysical law that such particles do not simultaneously possess position and measurement. For decades, the anti-Identity modern philosophers were pushing the former interpretation. But Aristotle has had the last laugh.

Brant Gaede 73 Report post Posted August 16, 2017 It depends on what zero is attached to. All numbers are epistemological. Zero by itself is not a number but is still epistemological. Now 20 or 20,000 is as much something as 19 or 7. "020" is nothing at all, it doesn't even have an epistemological place. (Maybe somebody can invent a place.) The invention of zero ranks with the invention of the wheel or harnessing fire.
