How’s your knowledge of the Crusades? Probably poor like most people. I have a lot of Greece and Turkey talk going on here around the house, so I make a modest continual effort to get educated. Here’s an image that links to the interactive page.
Looking forward to more of this. Three dimensional images created by the Hubble telescope, with motion added. Someone could get familiar with navigating the universe. Be sure and look at it on full-screen using that little square in the bottom right corner of the video.
The glittering tapestry of young stars flaring to life in this new NASA/ESA Hubble Space Telescope image aptly resembles an exploding shell in a fireworks display. This vibrant image of the star cluster Westerlund 2 has been released to celebrate Hubble’s 25th year in orbit and a quarter of a century of new discoveries, stunning images and outstanding science.
On 24 April 1990 the NASA/ESA Hubble Space Telescope was sent into orbit aboard the space shuttle Discovery as the first space telescope of its kind. It offered a new view of the Universe and has, for 25 years, reached and surpassed all expectations, beaming back data and images that have changed scientists’ understanding of the Universe and the public’s perception of it.
In this image, the sparkling centrepiece of Hubble’s silver anniversary fireworks is a giant cluster of about 3000 stars called Westerlund 2. The cluster resides in a raucous stellar breeding ground known as Gum 29, located 20 000 light-years away in the constellation Carina.
The stellar nursery is difficult to observe because it is surrounded by dust, but Hubble’s Wide Field Camera 3 peered through the dusty veil in near-infrared light, giving astronomers a clear view of the cluster. Hubble’s sharp vision resolves the dense concentration of stars in the central cluster, which measures only about 10 light-years across.
The giant star cluster is only about two million years old, but contains some of the brightest, hottest and most massive stars ever discovered. Some of the heftiest stars are carving deep cavities in the surrounding material by unleashing torrents of ultraviolet light and high speed streams of charged particles, known as stellar winds. These are etching away the enveloping hydrogen gas cloud in which the stars were born and are responsible for the weird and wonderful shapes of the clouds of gas and dust in the image.
The pillars in the image are composed of dense gas and dust, and are resisting erosion from the fierce radiation and powerful winds. These gaseous monoliths are a few light-years tall and point to the central cluster. Other dense regions surround the pillars, including dark filaments of dust and gas.
Besides sculpting the gaseous terrain, the brilliant stars can also help create a succeeding generation of offspring. When the stellar winds hit dense walls of gas, they create shocks, which generate a new wave of star birth along the wall of the cavity. The red dots scattered throughout the landscape are a rich population of forming stars that are still wrapped in their gas and dust cocoons. These stellar foetuses have not yet ignited the hydrogen in their cores to light-up as stars. However, Hubble’s near-infrared vision allows astronomers to identify these fledglings. The brilliant blue stars seen throughout the image are mostly in the foreground.
The image’s central region, containing the star cluster, blends visible-light data taken by the Advanced Camera for Surveys and near-infrared exposures taken by the Wide Field Camera 3. The surrounding region is composed of visible-light observations taken by the Advanced Camera for Surveys.
This image is a testament to Hubble’s observational power and demonstrates that, even with 25 years of operations under its belt, Hubble’s story is by no means over. Hubble has set the stage for its companion the James Webb Space Telescope — scheduled for launch in 2018 — but will not be immediately replaced by this new feat of engineering, instead working alongside it. Now, 25 years after launch, is the time to celebrate Hubble’s future potential as well as its remarkable history.
This visualization provides a three-dimensional perspective on Hubble’s 25th anniversary image of the nebula Gum 29 with the star cluster Westerlund 2 at its core. The flight traverses the foreground stars and approaches the lower left rim of the nebula Gum 29. Passing through the wispy darker clouds on the near side, the journey reveals bright gas illuminated by the intense radiation of the newly formed stars of cluster Westerlund 2. Within the nebula, several pillars of dark, dense gas are being shaped by the energetic light and strong stellar winds from the brilliant cluster of thousands of stars. Note that the visualization is intended to be a scientifically reasonable interpretation and that distances within the model are significantly compressed.
Boing Boing published a cartoon titled “Washington State's medical marijuana milieu is almost too good to be true”. Funny and a description of the current market in Washington State.
Normally I post a few times a day on Twitter (@sumner), which I have set up to automatically be re-posted to Facebook. I like to post Twitter size concepts of things that I read, usually with a link. Then, if there’s any conversation about it, it usually occurs on Facebook. I don’t have much of a Twitter following for any interactive discussion. Longer ideas I put up here, but there’s no dialog here.
The topics of greatest interest to me seem to be politics, economics, science, business, greed, hubris, hypocrisy, and irrationality. There’s plenty of interesting examples, and always controversy. Controversy is created in my own mind by the very nature of a particular topic. That’s why I post something about it. Usually there’s a predominant misconception involved, a twist, sometimes I accurately perceive it, sometimes I don’t, that usually involves some combination of naturally occurring or culturally programed biases. Often times it’s a matter of framing the subject.
By the very nature of most problems, they are complex. Solutions often seem to be a choice between the rock and the hard place. Some people shy away from reviewing life’s complex puzzles, in favor of whatever is the status quo. These folks usually never participate in my Facebook discussions. They’ve got me hidden from their timeline. Other people think that by posting a controversial topic I’m evangelizing for that particular socio-economic-political religion, usually for what they consider the Religion of The Left. “Name calling” is very popular among these people. Obtuse links to justify positions are a speciality. Open idea discussion is not a speciality.
I consider my posts an offer to engage in “competitive thinking”. Admittedly it’s not a popular game. Particularly to play fair. But life is hard. Determining what’s real, what’s important, and what’s just noise created by behavioral biases is not easy. Add in the necessity of not only making money, but keeping money, exploring confidence levels via competitive thinking is a good exercise. It’s just that only certain people can keep up with the game.
I haven’t posted for a while. Been having one of life’s distractions. I’m expecting to be back now. S-

Lesson: Now that derogatorily labeled “Obamacare” has been proven a resounding success, everyone will continue calling it “Obamacare”. D’oh!
And there are some article describing studies that came out:
- Business Insider: One Map Shows Exactly What Obamacare Has Done To The Country
- Forbes – Rick Ungar: Key Study On Obamacare 2015 Premium Rates Is Out And You Won’t Believe What’s Going To Happen
- NYTs: Is the Affordable Care Act Working?
- Forbes – Rick Ungar: Warning: More Good Obamacare News Reported Here-May Not Be Suitable For All ACA Detractors
“They ought to get a job!”: A common refrain of a middle class far closer to destitution than to the award-winning 1% self-described “job creators.” It’s an attitude condemning their near like-kind rather than their destination of ultimate desire. I usually ask, “How many jobs have you created for the job seekers?” It’s not as if the availability of jobs is a natural occurrence, like raindrops or leaves off of a tree.
Of course, jobs infinitum are available, but at what price? In India, my executive friends make some modest tens of thousands of dollars in compensation, but have live-in cooks, gardeners, and drivers who make what must be some few tens of dollars per day equivalent.
Pushing people into jobs begs the question: What if the jobs being produced don’t pay compensation substantial enough to support existence in the economic society? At what point is this economic abuse? Whether abuse of the employee, other individuals seeking survivable yet competitive employment, the employers competitors, or the taxpayer who ends up subsidizing the low-wage earners, and in doing so subsides the employer.
Or should this just be interpreted as a modern day version of state supported quasi-slavery?
Here’s what we now know for sure:
- Trickle down economics is a sham.
- The world was actually a better place with Saddam in power
- The American Enterprise Institute’s successful Romneycare plan in Massachusetts was in fact scalable into a successful nationwide Obamacare plan.
- Financial recessions ARE different from demand recessions.
- Outlawing something doesn’t make it go away. It turns the market over to organized crime, and the settling of disputes occurs with violence rather than in courts.
- There is nothing structural for the foreseeable future that will slow the increasing wealth capture by a shrinking group of plutocrats.
Most world leaders, including quite a few U.S. presidents, and the top financial 0.1% are actually seven foot tall shape-shifting reptilian humanoids from a different planet who start wars and are responsible for horrific events of all kinds in order to promote fear and hatred, which gives them strength and reproductive capacity.
Maybe you already knew that.
