thought for the day/ Blombos cave and the 21st century revolution in Archaeology

Lion man of the Hohlenstein Stadel

I grew up with the knowledge of the European(primarily French) cave paintings as the oldest human creative efforts. People often wondered if there was creative efforts like that further back in time because of how old our line of descent is(back to like 4 million years). Archaeology certainly has found much exciting things.  Today, archaeology is revolutionized.

The findings of Blombos cave, South Africa . . . of a red ocher block with abstract patterns,

Note, African's today like to paint themselves with red ochre,

The red ochre block above dates to ~ 75,000 B.C. . . . blowing away the archaeological paradigm of the twentieth century!

For much of the twentieth century, the controversy was, "did human brains magically flip some genetic switch?"  Or, "did ideas come and go?"  The last question means . . . did ideas enter human cultures for a period, then disappear in a kind of dark ages?  The twenty first century archaeology answers in the latter. During about a hundred thousand year period, cultures came and went.  They did not pass on their discoveries to the future.  Future people rediscovered ideas and fashioned them in new styles all their own. Seems that population size has something to do with sophistication of ideas.

Another problem I'd note is that for that hundred thousand years that more or less biological progress was made, there were ice-ages that would have brought cultures 'back to the stone ages' figuratively speaking! For instance in the European cave paintings, we don't see the abstract symbolism we've just found in Blombos cave of twice the age!

Twentieth century archaeology new well, that ancient people's kept hunter/gatherer skills even if farming.  They'd switch between the two depending on the weather. In the beginnings of mankinds march towards science/technology, until it was developed enough(say after the European renaissance), mankinds was still quite dependent on the course of nature. As mankind used technologies, they often found themselves in situations where they needed science/technology they were hopeless to develop in the time needed.  So, cultures would collapse back to a previous state of living.  This is what twenty first century archaeology is seeing.

- I should note the lion-man which graces the top of this post.  I liked to say that in cave painters time, the hands symbolize self-reflection.  But, creative combining of ideas(even if not logically correct), like the combining of animal with human forms we see in Egyptian art, didn't come till, well Egyptian times.  Well, this lion-man is dated to 40,000 years!

Also, with this lion-man creativity, almost certainly used as some kind of spiritual god(giving man the power of the lion; Native Americans for instance would wear big cat or bear skulls to take on the properties of these great beasts!), to take on the powers of these other animals that humans don't(possibly how the god concept evolved from such ancient times) . . . in a related biblical passage, there's a goat god mentioned in Leviticus 17-7.  Although, some translations are not literal/or hide it as 'demon'.  For instance King James Bible, which is quite imfamous for mistranslating to hide embarrassing passages(one could argue that the King James verison of the bible was written to hide all kinds of errors and embarrassing problems discovered since the Arab/Spain translations occurred/spurred learning in 1060 A.D.) does this. Here's the New International Version/translation, of Leviticus 17:7, "They must no longer offer any of their sacrifices to the goat idols[b] to whom they prostitute themselves."

- I feel like I should say something about the astonishing refusal to question things I'm seeing in today's elite intellectuals(in relation to ideas coming and going); but, for various reasons, I don't feel the need to.  They'll either run into problems, change back to critical thinking and defending rationality, or they'll go away.  So, I won't waste much more breath on scientific ethics here!

astro picture for the day

-Science news extra,

Oldest Stone Tools Unearthed in Kenya <-- link here.

- thought for the day extra - In an earlier article, probably Greek science, I pointed out that I found some Jacob Bronowski phenomenon in Homer's Iliad.  Well, I just found some in the Bible as well!

Judges 6:31 has Gideon tested as a god, "And Joash said unto all that stood against him, Will ye plead for Baal? will ye save him? he that will plead for him, let him be put to death whilst it is yet morning: if he be a god, let him plead for himself, because one hath cast down his altar." Or, more specifically, "if he be a god, let him plead for himself"

A little review of Jacob Bronowski is in order.  In his "Science and Human Values", he points out that mathematical science is analogy.  Then, he notes, that after the creative act, there must be the empirical test.  He liked to point out a shakespear example.  The above, shows a test to see if Gideon is a god.

There's some more good stuff about Gideon.  Judges 7 has Gideon amassing like twenty thousand troops.  But, God steps in and says, no, if you go in with that many, you'll crush them easily, and they won't think it's a miracle.  You're going in with three hundred soldiers! Judges 7:2, "lest Israel vaunt themselves against me, saying, Mine own hand hath saved me. "

And I can't help posting one more biblical goodie!  Judges 9:54 has a Abimelech telling his fellow soldiers to kill him, because otherwise, he will go down in history as being killed by a woman! From the King James version, "Then he called hastily unto the young man his armourbearer, and said unto him, Draw thy sword, and slay me, that men say not of me, A woman slew him. And his young man thrust him through, and he died."

astro picture for the day/ Umbral moonshine conjecture and quantum gravity?

ESA/NASA Hubble Space Telescope image

Mathematicians Chase Moonshine’s Shadow <-- link here: once again, mathematics turns out to show the way to solving the universe! I've pretty much forgotten everything about the classification of the finite groups.  This was a logical proof; one so large, it takes up four thick volumes.  But, in the process of proving it(no, I didn't know those four volumes; I just read various articles including notices at the American mathematical society), they found these monster groups.  Abstract algebraic structures that, geometrically, define symmetry. One could say quickly, aRb, bRc, and aRc, can kind of constitute a group, where R means some relation like +, or some other binary relation. Mathematicians proved a classification of all possible finite simple groups.  Simple groups can be likened to prime groups.  There's subgroups, and hence factor groups, and so you can kind of see from there an algebra of abstact objects/groups. Monster groups are abundant element groups.  Like astronomically large finite groups. They found them through a kind of taking a slice of them process. So, finding each one(26  total) was a major accomplishment in itself!

I suppose I could mention something about how mathematicians were able to classify every possible finite simple group.  Mathematicians back around late 1800s found that a single lie group can stand for an infinity of finite groups!  They tried classifying lie groups as well.  Likewise, they found a finite list of groups.  They proved most through the 20th century, but one - E8.  The classification of finite groups was, more or less, proved in the 1980s.  E8 was proven a few years ago - by computer.  It took a computer program to make up the deductive structure.  So, here, with the classification of finite groups and the solving of E8, we have mathematical proofs beyond the general comprehension of a single human. Then, there's the monster groups, which if you read the article, may hold the clue to quantum gravity, not to mention number theory!

astro picture for the day/ John Von Neumann video

ESA/NASA Hubble Space Telescope image

Jacob Bronowski was forever in awe of John Von Neumann.  Jacob seemed to suggest that John Von Neumann was the smartest man he ever knew.  John Von Neumann didn't commit himself exclusively to mathematics.  The mathematics he did, mentioned in the video, were often not definitive.  John Von Neumann's work on Hilbert's fifth problem was just a special version. A collection of mathematicians solved special versions of Hilbert's fifth problem - about lie groups.  If I state it, it would sound so trivial that it would just not sound like anything worth working on.  John Von Neumann worked on other esoteric mathematics few people today consider worth working on - Lattice theory for instance.

I can't help noting that this video contains 'the only video of John Von Neumann' in the world!  It's amazing to think that even in John Von Neumann's time, it was rare to have much video media on him!  I also can't help noting how Einstein like he seemed.  I wonder how influenced he was from the Einstein example. 

John Von Neumann's science and engineering so to speak were perhaps his biggest influence. His theory of games is used by the U.S. military for one.  Curiously, U.S. military's use of game theory doesn't seem to be have been used in this Russian/Ukraine conflict. The U.S. military and the U.S. President seems to have not seen this one coming! His mathematical foundation of quantum mechanics talked about hidden variables which led to the ideas about quantum computers. John Von Neumann's work on computers led the first electronic digital computers and even A.I.(or at least he and everyone else hoped - he wrote a book 'The Computer and the Brain'). 

Quote for the day extra,

"Moreover what I have given in the second book on the nature and properties of curved lines, and the method of examing them, is it seems to me, as far beyond the treatment in ordinary geometry, as the rhetoric of Cicero is beyond the a,b,c's of children . . ." - Descartes

Ancient geometers from The Greeks to Descartes concerned themselves with the three Delian problems, which led to Conics in the hands of Appollonius(culminated in his works actually).  Descartes actually derived his coordinate geometry from solving some of these ancient problems in a new way.

Most students today learn systems of equations later after to learning equations.  For Descartes, this was a kind of starting point for solving these ancient problems.  Descartes understanding of algebra was far deeper than what students today learn. Today, some students might hear about various proportionality rules beyond a/b=c/d such as a+b/b=c+b/c and so on. Today, they are set aside if the teacher and students have time.  Back in Euclid's time, they were essential.  In a similar way, systems of equations were essential, and today, well, they are much later and in a different way. All this is an example of how original inspirations for discovery gets forgotten, and the importance of studying history . . . as far as possible!

Astro picture for the day/ Gobekli tepe video

ESA/NASA Hubble Space Telescope image

Gobekli Tepe video,

Gobekli Tepe is one of the most exciting archaeology finds since the Nebra Sky disk!(lol) Seriously though, people have said many times that Gobekli challenges whether pre-agricultural cultures can build on a major scale. They're suggesting that this is built by cultures before agriculturalism. The transition between hunter/gatherers to agriculturalism is one of the great mysteries of Anthropology. The crossing of such a divide . . . to just stop what you're doing and start doing something else(stop from hunting/gathering and start doing agriculturalism) always seems to be an impossible chasm.

  Let's assume that is true.  Could it be that in the societal organization to build, and feed the builders, they found enough insights to make for agricultural civilization?  I don't here anyone making that suggestion.

astro picture for the day/ new most exciting archaeological disproof of Jesus Christ

Image Credit & Copyright: Rogelio Bernal Andreo (Deep Sky Colors)

B.C.(maybe early A.D.) cup with "Christ the Magician" inscription

< link above, Here we see that the use of the name Christ was in common use before the supposed life of Jesus Christ.  Or, if it's early A.D. why doesn't this mention Jesus Christ and why call him a magician instead of Son of God?

This Christ the Magician cup should make the headline news; but, of couse, it won't!

astro picture for the day

ESA/NASA Hubble Space Telescope image

Found yet another pretty good Werner Von Braun documentary.  This is one of the first PBS Nova videos.

Some of what I posted on the youtube actually,

"A couple remarkable things already . . . the narrator; I've heard that voice before; that voice narrates the real, original "Planet Earth" of the 1980s, and not the mere photography(however good the photography was actually) of the Sigourney Weaver Planet Earth(I love Sigourney Weaver's Aliens movies).

Another interesting thing about this video is getting to see the most interviews of General Dornberger I've ever seen. It's been my understanding that General Dornberger was the buffer between Hitler and Werner Von Braun; General Dornberger was the reason Werner Von Braun was able to wear civilian cloths for six years while the rocket program was Nazy funded for six years until 1938 when the Nazies finally took notice and acknowledged a little bit that this rocketry business might go somewhere(Hitler for the most part didn't believe in rocketry).

When Werner Von Braun surrendered to the U.S.(instead o the Russians) at the end of the WWII . . . well, there's a rather famous video of Werner coming out with a cast.  Werner comes out one side, and Dornberger comes out the other side in a hat.  You see Dornberger, then some American private, and then Werner Von Braun.

This video also has Dieter Huzel who wrote "From Peenemunde to Canaveral", a book I found in a community college.  It's good to see him live; also, to find out that it was he who hid the V2 information in the V2 tunnels."
