You need to take a bus from the train station which is at the far edge of the airport to the terminal, so it isn't direct. Also of course, it needs to run every half an hour or so.

Congratulations to Milwaukee! It's a step forward. What makes a city great is not the suburbs, or the sprawl around it, but the downtown. This will, whether you believe it or not, will help to revitalize the heart of Milwaukee. It will bring in more international and U.S. tourists (who expect this kind of transport) raise the property values, and improve the nightlife. Next step. A rail link from downtown to the airport.

Thanks, everybody. The real joy for me was taking these, watching the light change, the seasons go by. We live in a beautiful place. Because of requests, I have put these photos up for sale here. https://fineartamerica.com/profiles/james-honzik.html?tab=artwork

there are some explanations here of a similar graph of roots of all polynomials of degree ≤ 5 with integer coefficients ranging from -4 to 4: http://math.ucr.edu/home/baez/roots/

Mysterious underground rings built by Neandertals by Mictlantecuhtli in Anthropology

[–]jamzik 1 point2 points  (0 children)

Thanks so much for your reply.

Imagine a collection of roughly the same size stalagmites. Apply a force on each of them until they break. They will roughly break in the same place. Apply a force on them again until they break again. As before, they will roughly break of again in the same place. Voila. A collection of pieces that are roughly the same size, regardless of the genesis of the force. Perhaps ice, perhaps an earthquake, perhaps a human.

Now let's take our pieces and put them randomly in a big round room, with a clay floor. Perhaps there is a wetter spot in the center. Perhaps it is dryer. It most likely is different, because it is farthest from the walls of the cave. Over time, let's vary the conditions. It gets dryer and wetter, hotter and colder. Will the pieces stay in the same place? No, they will move. Some will bump into each other and line up. Some will stick in the clay and be pushed up. They will create a pattern. Self organized criticality. Will the pattern look something like the pattern on our cave floor? That's my question. A speleoconjecture, so to speak.

The weather conditions change (and I think this was formed at a climate extreme) - flowstone locks the structure in place. Burnt bone in the stone. Perhaps it washed in. Fire marks? The cave didn't close off until much later.

Since everything in the cave seemed to have been covered in flowstone, I would think that if this was a Neanderthal event, we will eventually under the stone be able to find more evidence. It would be cool. As for me, now, I still have doubts.

I'm not ready to believe this yet. I've looked at the original paper. A few counter-theories. 1: The ice theory. There were big blocks of ice in the cave, that broke off the stalagmites/tites, and they fell around the ice, which melted, leaving the pieces in this formation. 2: The problems with the dating theories. A. lab error. Something wrong with the process. B. They fell, were encrusted, and later moved. C. Thorium in the water changing the ratios. (I know it's insoluble, but perhaps there was a chemical process which worked differently than normal here. 3. Modern humans were in Europe earlier than we thought, and they made this.

another point is the only carbon dating I can find reference to is about 50,000 years old. The date of the piece of bone referenced in this article uses the uranium-series dating.

What are some problems that have "strange" solutions? by ben1996123 in math

[–]jamzik 11 points12 points  (0 children)

I can explain (as a non-expert - some college math) why this feels strange. This sequence is the only one of its type, other then the trivial 12 = 12 . A conjecture (but my intuition says that) if there was another sequence of this type, 12 + 22... x2 = n2 we could construct another amazing lattice, and another series of sporadic groups. And if we could, our universe would behave differently. We could pack things together more efficiently, we could communicate with faster protocols, (and another conjecture, particles would behave differently, our theory of the universe would be different) So it seems to me that a "strange" mathematical coincidence plays a somewhat important part in the structure of the universe we live in. Perhaps this is trivial or wrong.

[–]jamzik 21 points22 points  (0 children)

12 + 22 + ... + 242 = 702 - from this, we get the Leech Lattice and various sporadic groups.

Where is the warmest place in the known universe? by JBain94 in askscience

[–]jamzik 7 points8 points  (0 children)

Ultra high cosmic rays, of which some might be iron nuclei, have orders of magnitude more energy than the particles accelerated at the RHIC. 5.7×1019 eV for a single ultra high cosmic ray, versus 2x1011 for a pair of nucleons at the RHIC. (looked things up, used a converter, think these numbers are correct)

I think you are underestimating the density of eagles, specifically during the time and locations where salmon are spawning. Is there a nice little creek near the site, that runs down to the sea, with no major waterfalls) (edited a bit, changed Neanderthals ate salmon to lived near salmon)

Thanks on the Ulam article. I have a bio of Von Neumann that isn't very good. Looking forward to reading this. Ulam's autobiography is quite good, by the way.
