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."

astro picture for the day/ some thoughts on Human intelligence

ESA/NASA Hubble Space Telescope image

- A thought about intelligence that I've meant to post for a long time, but haven't because I've yet to reread some stuff(I still haven't reread these things) . . .

I've often thought that evolution is learning and vice versa, and that life is a dynamical system that evolves(the religious who fight against the view of life as evolving are arguing for static spirituality), so life is intelligence.  But, what about the science and technology and the ability of Humans to be able to learn something about the universe?

Well, As I've more or less started out this blog about the nature of mathematical knowledge, I argue that like the way science and technology experienced an outbreak with the agricultural revolution, intelligence that separates us from the other life sprang out long before. Some attribute it to bipedalism and the use of the thumb.  Maybe It is something this simple. But, I don't see a lot of people satisfied with that explanation. However the case may be, intelligence potential is in life before bipedal hominids, and then for some reason, the ability to figure out the universe sprang up in bipedal animals much like science and technology did with the agricultural revolution of ~ ten thousand years ago.

-  That's one older thought that I'm still not exactly satisfied with; another thought about intelligence is that of consciousness.  Seems to me that we are conscious of something when we have knowledge of it.  Not facts knowledge like bits in a computer.  Bits that a computer isn't conscious of till it decided to use it.  But, knowledge that connects and unifies facts.  Conceptual knowledge. When you solve a puzzle, figure something out, you become more conscious than you were before. So, those who do science/mathematics tend to be more conscious than those who don't!

See, everyone notes the strange feeling of free will.  In mathematical science knowledge, we define a concept in such a way that we can detach it from the source and use it elsewhere.  The wonder is always how we Humans can abstract a word and place it before or after a verb; animals can't generally do that. I hit the car; the car hit me! Mathematical definitions have  standard of reversibility. This reversibility detaches the concept and allows one to use it elsewhere.  "Collinear point are points that lie on the same line . . . points that lie on the same line are collinear points"  So, these concepts begin to live a life of their own, much as thinking human beings seem to be conscious of things and live a life of their own. 

It's a bit like a strobe light; a light that blinks on and off.  If you vary the speed of the on off light, you can make certain things like propeller blades that are spinning look like they're standing still. If you don't have the right speed ideas in your head, you cannot be conscious of things.  When you figure out something, you are able to get the speed adjusted to the patterns of nature just right to detect what you couldn't before. Like standing next to a stream; generally, the stream looks like chaos; but if you pick a point and follow it downstream, all of a sudden you see a particular pattern that stays the same for the most part as it flows downstream! You even feel much of the sensation that mathematical scientist feel when they figure something out!

thought for the day . . . French Chateaus

The 1500 Renaissance almost overshadows the great sea voyages that discovered the Americas(and the world really). The wealth that came from this discovery powered the Renaissance into the modern era where it might have stalled like most social movements.  Conversly, the wealth brought by the sea voyages paid for everything back home that was inspired by the Italian renaissance.

here's some of what's inside the "Ducal palace" of Urbino,

there's a waterworks under the castle/palace,

and perhaps the most famous part of the Ducal palace, is the formerly warlord's library,

I bring up this Ducal palace of Urbino, Italy because it's an example of a castle turned into a palace before all the French Chateaus.  And since the French Chateaus are inspired by Italian everthing, it seemed a good place to start!

Here's the Château de Chenonceau . . . I like this one because of the arches in the river.

The Château de Villandry . . . this one has very elaborate gardens including waterworks; this picture doesn't do it justice.

Here's a pretty good video of it

And here's the Clos Luce,

Doesn't look like much . . . but, it did house one rather famous historical figure in his dieing years - Leonardo Da Vinci! He brought the Mona Lisa with him(maybe why it's in a French museum today!).  Today, engineers have made working models of various Leonardo Da Vinci machines.

Here's a pretty good video of it!
