I used Dave Foxx's method to adapt a code 80 15 degree crossing to Atlas Trutrak a couple of years ago. I really think that the method of soldering the smaller code rail on top os a flattened joiner which is installed on the larger code rail is *MUCH* easier and quicker than trying to file a slope in the taller railhead to match the height.

I have built up the entire bench work and the main line section of the layout including the double wye. The problem I am having involves three locations where the engine I am using for testing derails.
The other problem I have is a couple of locations where I didn't notice while building that there are small gaps in one rail where they join. I abandoned the layout after I worked out the kinks (literally) and discovered that it was the classic bowl of spaghetti design. Ed the bench work looks great but I don?t understand the reason for the four power districts. One of the problems I am having is right in the middle of the left side 22" modification.
I did figure out one of the derailments I was having, although I feel sort of like an idiot for this one. Upon further inspection of the area with the problem, I noticed a small bump in the road bed.
I was going to suggest the you already own the two best tools for finding track problems - your eyeballs and your fingers. GreetingsOur club, the Baltimore Area N-Trak did a project layout for the B&O Elicott City Museum's Festival of Trains.
Two-and-a-half days after a dramatic sea rescue, the tugboat crew hauling a space shuttle fuel tank to California bid farewell to some unexpected passengers last night in San Diego. A guide to interesting stuff going on in space science, space exploration, and space advocacy.
A paper in Nature this week that uses reversible-jump MCMC, phylogenetic trees, and Bayes factors. The aim of the paper is to establish that societies with human sacrifices are more likely to have become stratified and stable than societies without such niceties. The methodological question is then how can this be tested when considering those are extinct societies about which little is known. All of this provides an excuse to show this film of the Vienna Philharmonic under the baton of Leonard Bernstein playing the gorgeous third moment (marked Ruhevoll) of Symphony No. Pairs of occulting galaxies allow for the dust in galaxies to be mapped very accurately and give insight into the attenuation law in the outskirts of galaxies. Most of us think of dust as the unfortunate substance that is forever collecting on furniture in our homes, something we try to get rid of during half-hearted attempts at spring cleaning. In todaya€™s paper, the authors describe a method to understand how much dust is in a given galaxy and how that affects the light from the object.
One initial result is thatA the authors have determined that the dust in the outskirts of galaxies extends farther out than the observed visible light would indicate. The ongoing STARSMOG program to study occulting galaxies is a Hubble Space Telescope program to continue studying the effects of dust at large radii in galaxies. The crew of the tugboat hauling the last unflown space shuttle external fuel tank to California reports they have rescued four passengers from a fishing boat that sunk off the coast of Mexico. On a whim, I bought this a€?travel booka€? in a nice bookstore at the end of Rue Mouffetard, Paris, when looking for a weekend travel guide!
One of a series of quick posts on the six sections of my book The Big Picture a€” Cosmos, Understanding, Essence, Complexity, Thinking, Caring. In this final section of the book, we take a step back to look at the journey wea€™ve taken, and ask what it implies for how we should think about our lives. There are nevertheless some things worth saying, because there are a lot of untrue beliefs to which we all tend to cling from time to time. Of course there are also incorrect beliefs on the religious or non-naturalist side of the ledger, from the existence of divinely-approved ways of being to the promise of judgment and eternal reward for good behavior.
The finitude of life doesna€™t imply that ita€™s meaningless, any more than obeying the laws of physics implies that we cana€™t find purpose and joy within the natural world. Opportunity arrived at its current location on sol 4345 to begin investigation of an outcrop on the crest of a ridge near the west end of Marathon Valley.
These are chosen so that, if our suggestively named variables really were partials, these 1-forms would vanish. Like I said above, Dennis takes this amazing theorem of Cartan and connects it to an amazing theorem of Engel, and then generalizes the whole story to nearly all simple complex Lie algebras. Many of you may know Darbouxa€™s theorem in symplectic geometry, which says that any two symplectic manifolds of the same dimension look the same locally.

I cut the sides of the roadbed off of a spare piece of trutrak and glued it in to match the cast roadbed color and profile.
Besides, that is how the 1:1 railroads did it (matching the tops of the railheads rather than grinding the railhead). Import charges previously quoted are subject to change if you increase you maximum bid amount.
There are four insulators in the rails to allow for the operation of a PSX-AR for the unbuilt yard area.
I see no problems with the tracks and don't 'feel' anything out of place, but at some speeds the engine derails. What I mean is I have four areas that are fed from the same booster through four circuit breakers (PSX-4). The hypothesis to be tested is then about the evolution towards more stratified societies rather the existence of a high level of stratification.
Grouping together moderate and high stratification societies against egalitarian societies, the authors tested independence of both traits versus dependence, with a resulting Bayes factor of 3.78 in favour of the latest.


Well, OK, they don't actually say that, but they basically indicated why this might be a never-ending loop.Still, let's think about it this way instead. That isotope has a very long lifetime, of order 10^21 years, and undergoes the lepton-number-conserving double beta decay Xe136 a†’ Ba136 2e- 2I?bar. One is that this piece (though not this performance) was one of the late Harry Krotoa€™s selections for Desert Island Discs. But what seems mundane and annoying here on Earth is one of the most important thingsA that astronomers try to characterize. Picture two occulting, or overlapping, galaxies, one of which is in the foreground and the other in the background, as shown in Figure 1.A You can imagine that the light from the galaxy in the background will shine through the galaxy in front, illuminating the dust content and structure of the foreground galaxy. An image and schematic showing how overlapping galaxies can give information about dust in the foreground galaxy.
Astronomers have proposedA many different models to describe how the dust in galaxies affects light at different wavelengths.
I was fairly intrigued about this road-trip on an antique Soviet side-car, following the route of Napoleona€™s army when retreating from a burning Moscow. I intentionally kept it short, because I dona€™t think poetic naturalism has many prescriptive advice to give along these lines.
Many (most?) naturalists have trouble letting go of the existence of objective moral truths, even if they claim to accept the idea that the natural world is all that exists.
Naturalists accept that life is going to come to an end a€” this life is not a dress rehearsal for something greater, ita€™s the only performance we get to give. The absence of a God to tell us why wea€™re here and hand down rules about what is and is not okay doesna€™t leave us adrift a€” it puts the responsibility for constructing meaningful lives back where it always was, in our own hands. You can see why someone would believe it, and work to reconcile it with what science has taught us about the nature of reality. Demanding in its own way, it may not give us everything we want, but it fits comfortably with everything science has taught us about nature.
Even better, when he writes down his PDE explicitly, the exceptional Jordan algebra makes an appearance, as we will see. To understand this, we need to see how PDE can be realized geometrically, using jet bundles. This correspondence between prolongations and holonomic sections is the key to thinking about jet bundles. In contact geometry, the analogue of Darbouxa€™s theorem holds, and goes by the name of Pfaffa€™s theorem. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. It would have been a lot easier to have planned for the below mounting switches than to try to mount them after.
I will do some measurements to verify that I have the correct diameter for the 22" radius tracks.
I removed the nail by sliding a small putty knife under the road bed removing the nail , the problem disappeared. During your grandfather's time, presumably, ALL the atoms or energy that will make you are already there, only they are all not together to form you.
What the monks hope to observe is the lepton violating neutrinoless double beta decay Xe136 a†’ Ba136+2e, which would show as a peak in the invariant mass distribution of the electron pairs near 2.5 MeV. Another is that I had occasion to sort out my CD collection recently and I realised in doing so that I had more recordings of this Symphony than any other. My favourite recording of this symphony is actually by Von Karajan with the Berlin Philharmonic on Deutsche Grammophon, but this is well worth watching to see the communication between Lenny and the band. Sure, dust may not be as explosive as a supernova or as dramatic as a black hole, but every single observation we have of light from astronomical sources at shorter wavelengths, such as UV and optical light, comes to us filtered through the gas and dust spread out through the universe, thereby attenuating the signal. Ideally, the background galaxy is an elliptical galaxy and the foreground a spiral galaxy.A The authors have amassed a sample of about 2500 occulting pairs of galaxies collected from the Sloan Digital Sky Survey (SDSS), Galaxy And Mass Assembly (GAMA), and GalaxyZoo in a project called STarlight Absorption Reduction through a Survey of Multiple Occulting Galaxies (STARSMOG). The light from the background galaxy (orange) is attenuated by dust in the foreground galaxy (blue).
One of the lingering questions is then how that dust came to be so far out in the disk of the galaxy. Using the signal from the background galaxy (red) and the signal from the region where the foreground and background galaxies overlap (green) informs how the dust is affecting the observations. In fact, I have always been fascinated by the way Napoleon got mired into the Campaign of Russia, and not only because of Charles Joseph Minarda€?s amazing graphical summary of the Campaign! Resisting the temptation to give out a list of a€?Ten Naturalist Commandments,a€? I instead offer a list of a€?Ten Considerations,a€? things we can keep in mind while we decide for ourselves how we want to live. Teach them to fish, and you feed them for a lifetime.a€? When it comes to how to lead our lives, poetic naturalism has no fish to give us. But you cana€™t derive ought from is, so an honest naturalist will admit that our ethical principles are constructed rather than derived from nature. It simply is, unguided and unsustained, manifesting the patterns of nature with scrupulous regularity.
It bequeaths to us the responsibility and opportunity to make life into what we would have it be. I do think that the basic precepts of naturalism provide a framework for thinking about the world that, given our current state of knowledge, is overwhelmingly likely to be true. And the third is that I heard a discussion on Radio 3 recently in which a record company executive noted that while sales of opera performances on DVD were very healthy, it was very difficult to sell DVDs of symphonic concerts.
And if you think Mahler is always gloomy and angst-ridden, hopefully this will make you change your mind. With this sample, they can to begin answer questions such as how far radially does the dust extend in galaxies? Using the overlapping region in the a€?Venn diagrama€? of the two galaxies (black box), the combination of the light from the two occulting galaxies allows for very accurate descriptions of the dust distribution, density, and composition. Continuing research will tell if the dust moved there in some kind of radial flow or if it was formed there originally. The reddening law for the outskirts of the foreground galaxy is therefore much easier to model. Initial pilot images were takenA by an integral field unit (IFU), which is a type of spectrograph that enables astronomers to see both images and spectra from an object.
Despite advices from scientists and diplomats, Napoleon did not want to pay any heed to the climate constraints. The splendor of the cosmos, spanning billions of years and countless stars, culminated in the appearance of human beings here on Earth a€” conscious, aware creatures, unions of soul and body, capable of appreciating and returning Goda€™s love. Over billions of years it has evolved naturally, from a state of low entropy toward increasing complexity, and it will eventually wind down to a featureless equilibrium condition.
But the hard work of understanding the details of how that world works, and how we should shape our lives within it, is something we humans as a species have really only just begun to tackle in a serious way.


Actually, given that the models are quite simplistic, I do not agree that those Bayes factors prove anything of the magnitude of such anthropological conjectures. But they are all there!But here you come along from another time, popping into existence in your grandfather's time. Namely this video posted on your tube.The conclusion is that humans are destined to explore the Local Group of galaxies, and that is it. I am not particularly surprised by that but I have to say that I love the visual as well as the auditory experience of a classical concert.
And he did not account either for the sacrificial tendencies of the Russian troops and irregulars. Ita€™s more like poetic naturalism helps us figure out that there are things called a€?fish,a€? and perhaps investigate the various possible ways to go about catching them, if that were something we were inclined to do. More than enough raw material to construct workable notions of right and wrong, no less valuable for being ultimately subjective. Our mortal lives are part of a larger span of existence, in which we will continue to participate after our deaths. Aren't you violating conservation of energy by adding MORE energy to the universe that are not accounted for?
And this video has received a bit of circulation on the inter-webs, promoted by a few sciency people.The problem, however, is that it is wrong. In particular it depends on the mass of the lightest neutrino (x-axis in the plot) which is currently unknown. A large group of talented people coming together to make music is a great thing to watch, and it also helps understand the music a bit too. The attenuation curve derived from these observations can be much more accurately modeled given the data from both galaxies than if only single galaxy observations were available.
Ita€™s up to us what strategy we want to take, and what to do with our fish once wea€™ve caught them. Not a break-the-laws-of-physics kind of miracle; a miracle in that it is wondrous and amazing how such complex, aware, creative, caring creatures could have arisen in perfect accordance with those laws. BayesTrait was also instrumental in deriving MLEs for the various transition rates, a€?in order to inform our choice of priorsa€? (!).
The basic idea is that accelerating expansion due to the presence ofA dark energyA means that the separation of objects will get faster and fast, and so it will be a little like chasing after a bus; the distance between the two of you will continue to get bigger and bigger. Ia€™d much rather go to a live concert (even a mediocre one) than listen to a CD (even a very good one), but failing that Ia€™d definitely go for a DVD. And finally, does the effect of dust change in the outer regions of a galaxy where there are fewer metals? So while we contemplate the layers of dust on our furniture, some astronomers will be working on STARSMOG to understand the dust in galaxies much more precisely than current capabilities.
The book however gets very quickly boring as the painfully slow and uncertain drive cannot equate the horror of the hundreds of thousands of deaths in Napoleona€™s army fleeing back to Paris. BayesTrait has an MCMC function used by the authors a€?to test for correlated evolution between traitsa€? and derive the above Bayes factors. This part is correct, and in the very distant universe, there will be extremely isolated bunches of galaxies whose own gravitational pull overcomes the cosmic expansion. But oscillations are not sensitive to the absolute mass scale; in particular, the lightest neutrino may well be massless for all we know. Driving by sub-zero temperatures sharing roads with indifferent Ukrainian truck-drivers and repairing every now and then the side-cars that fell apart does not appeal for long, especially whenA  It only takes the side-cars 13 days to reach Paris and there is no tension in the road trip as they could really stop any time. On top of that, the discourse about the charisma of Napoleon and the complaints about the reduction of our life scope from heroic time to pampered materialists is pretty annoying, and so is the permanent glorification of the Russian soul. And 10a?? iterations (repeated 3 times for checking consistency)a€¦ Reversible jump is apparently used to move between constrained and unconstrained models, leading to the pie charts at the inner nodes of the above picture. A This so-called normal hierarchy case is shown as the red region in the plot, and is clearly out of experimental reach at the moment. Once we are out there traveling in the "expanding universe" then the expansion works in our advantage, increasing the distance not only between us and where we want to get to, but also between us and home.
On the other hand, in the inverted hierarchy scenario (green region in the plot), it is the two heaviest neutrinos that have a significant electron component. The trees on the left and the right are completely identical, the difference being in the inference about stratification evolution (right) and sacrifice evolution (left).
While the overall hypothesis makes sense at my layman level (as a culture has to be stratified enough to impose sacrifices from its members), I am not convinced that this involved statistical analysis brings that strong a support. A Finally, there is also the degenerate scenario (funnel region in the plot) where all 3 neutrinos have very similar masses with small splittings, however this scenario is now strongly disfavored by cosmological limits on the sum of the neutrino masses (e.g. I've spoken about this paper many times (and read it, it is quite excellent) but for this post, what we need to look is at the "conformal" picture of our universe. I don't have time togo into the details here, but the key thing is that you manipulate space and time so light rays trade at 45 degrees in the picture.
The strength of this limit depends on some poorly known nuclear matrix elements (hence the width of the blue band). Here's our universe.The entire (infinite!) history of the universe is in this picture, mapped onto "conformal time". But even in the least favorable scenario future, more sensitive experiments should be able to probe that region. Thus, there is a hope A that within the next few years we may prove the Majorana nature of neutrinos, or at least disfavor the inverted hierarchy scenario. If we extend our past light cone into the future, we can see the volume of the universe acceptable to us, given the continued accelerating expansion.
We can see that encompasses objects that are currently not far from 20 billion light years away from us. This means that light rays fired out today will get this far, much, much larger than the Local Group of galaxies.But ha!
Puny humans in rockets have no chance!Again, wrong, as you need to care about relativity again. I wrote a paper about this with two smart students, Juliana Kwan (who is now at the University of Pennsylvania) A and Berian James, at Square.
I am more than happy to acknowledge Jeremy Heyl's earlier work that inspired ours.One tiny last point is the question whether our (or maybe not our) decedents will realise that there is dark energy in the universe.
Locked away in Milkomenda (how I hate that name) A the view of the dark universe in the future might lead you to conclude that there is no more to the universe than ourselves, and it would appear static and unchanging, but anything thrown "out there", such as rocket ships (as per above) or high velocity stars, would still reveal the presence of dark energy.There's plenty of universe we could potentially explore!
