The math hidden in Van Gogh’s Starry Night

An evening pause: This pause is very apropos to some of Juno’s more recent Jupiter images.

Hat tip to Mike Nelson.

By the way, I am open to Evening Pause suggestions from all my readers. If you have seen something that you think might fit as an evening pause, make a comment here telling me you have a suggestion. Don’t provide the link to the suggestion. I will email you so that you can send it to me direct and I can then schedule it.

Trump budget proposal

The Trump administration today released its overall rough budget plan for 2018. This is not a detailed budget, but an summary of their plan, indicating where they wish to cut and where they wish to increase budgets. The proposal is also not complete, making no mention of the administration’s budget plans for many departments, such as the National Science Foundation.

Science research in the federal government is significantly impacted, but not as badly as most of the articles you will read in the mainstream anti-Trump, Democratic Party press. A few examples:

I must note that not all the news stories are blindly hostile to this budget proposal:

Of all the science agencies, NASA probably came off with the least change. The budget cuts only about 5% from the agency’s Earth science budget, while cutting some specific Earth science missions. The budget also supports SLS/Orion, though it finally puts the nail in the coffin of the asteroid redirect mission, an Obama proposal that has never garnered any interest from anyone else.

The Trump budget proposal in context

The key to understanding all these budget cuts is to see them in context, to compare the 2018 proposed budgets with the budgets these agencies received in the past. The table on the right gives some of this context (numbers shown are in millions) for several of the science agencies most effected by the proposal. The proposal is not detailed enough to pin down the changes for many other science agencies, but from this table it is clear that the Trump administration is not calling for the end of science, and is proposing some reasonable cost cutting, something that has been rare in government for many years.

What will be missed by most of the press about this Trump budget proposal is that it is not trying to trim the size of the federal government. While it cuts spending in many departments, those cuts are entirely aimed at providing room to raise the budget of the Defense Department by $54 billion. While I can applaud the desire of the Trump administration to be revenue neutral, the stark fact remains that by remaining revenue neutral Trump still leaves us with a gigantic annual federal deficit. They have made no effort to balance the overall budget.

Worse, this proposal would repeal the Budget Control Act of 2011, which imposed sequestration to the federal budget and has actually done the most in the past half century to bring that budget under control. Once this act is repealed, it will allow the spenders in Congress (of which the Republicans are as guilty as the Democrats) to open the floodgates once again. This will not be good.

Let me add one good aspect of the Trump budget. It proposes to eliminate a whole range of government political agencies that accomplish nothing but provide pork or to propagandize the Democratic Party’s positions:

The Budget also proposes to eliminate funding for other independent agencies, including: the African Development Foundation; the Appalachian Regional Commission; the Chemical Safety Board; the Corporation for National and Community Service; the Corporation for Public Broadcasting; the Delta Regional Authority; the Denali Commission; the Institute of Museum and Library Services; the Inter-American Foundation; the U.S. Trade and Development Agency; the Legal Services Corporation; the National Endowment for the Arts; the National Endowment for the Humanities; the Neighborhood Reinvestment Corporation; the Northern Border Regional Commission; the Overseas Private Investment Corporation; the United States Institute of Peace; the United States Interagency Council on Homelessness; and the Woodrow Wilson International Center for Scholars.

Getting these eliminated will at least be a start to cleaning up the mess in Washington.

Want to watch a nuclear bomb go off? You can!

Engineers at Lawrence Livermore National Laboratory (LLNL) have obtained declassified films of many of the nuclear tests performed by the U.S. from 1945 to 1962 and are digitally scanning them and preserving them for posterity.

Conducted by LLNL weapon physicist Greg Spriggs and a team of film experts, archivists, and software developers, the project’s goal was to track down as many as possible of the ten-thousand 2,400 frames per second reels of film. This was because the cine film, and its immense historical and scientific value, was in danger of being lost for all time. The reels were mostly of acetate stock that was not stored under anything like ideal conditions and was slowly decaying or being attacked by fungus and microbes.

“You can smell vinegar when you open the cans, which is one of the byproducts of the decomposition process of these films,” says Spriggs. “We know that these films are on the brink of decomposing to the point where they’ll become useless. The data that we’re collecting now must be preserved in a digital form because no matter how well you treat the films, no matter how well you preserve or store them, they will decompose. They’re made out of organic material, and organic material decomposes. So this is it. We got to this project just in time to save the data.”

You can view a number of the films at the second link above. I have embedded below the fold just one, from Operation Teapot in 1955. This was a series of 14 tests in Nevada. In this particular video the explosion occurs in the air, and you can sense the incredible force of the explosion when the shock wave hits the ground and bounces back, producing the mushroom cloud. Not much would have survived that impact.

SpaceX successfully launches commercial satellite

The competition heats up: SpaceX tonight successfully launched Echostar 23.

This launch is almost four weeks after their last launch, which sent a Dragon capsule to ISS. Their goal this year has been to do one launch every two weeks, a goal they have not yet reached. The next launch, which will also place a commercial communications satellite into orbit, is tentatively set for March 27, and will also be the first launch that reuses a first stage. If they make that happen it will be first time they have hit the two week launch rate this year. They will then try to follow with another Dragon resupply mission, this time reusing a Dragon capsule for the first time.

Less evidence of dark matter in early universe

The uncertainty of science: Astronomers have discovered less evidence of dark matter surrounding galaxies in early universe.

Stars in the outer regions of some far-off galaxies move more slowly than stars closer to the center, indicating a lack of dark matter, astronomer Reinhard Genzel and colleagues report online March 15 in Nature. If confirmed, the result could lead astronomers to reconsider the role dark matter played in early galaxy evolution and might also offer clues to how nearby elliptical galaxies evolved.

In contrast with these distant galaxies, stars orbiting on the outskirts of the Milky Way and other nearby galaxies move too fast for their velocities to result only from the gravity of gas and stars closer to the galactic center. If visible galactic matter is embedded in a cloud of invisible dark matter, though, gravity from the invisible matter can explain the high stellar velocities. Using stars’ orbital velocities in nearby galaxies as a reference, astronomers expected that stars in galaxies farther away would behave similarly. “Turns out that is not the case,” says study coauthor Stijn Wuyts of the University of Bath in England.

In other words, scientists at this moment really have no idea what causes the faster rotation in the outskirts of modern nearby galaxies.

Titan’s fizzy oceans?

New research suggests that the hydrocarbon lakes of Titan might periodically fizz with nitrogen bubbles.

A recent NASA-funded study has shown how the hydrocarbon lakes and seas of Saturn’s moon Titan might occasionally erupt with dramatic patches of bubbles.

For the study, researchers at NASA’s Jet Propulsion Laboratory in Pasadena, California, simulated the frigid surface conditions on Titan, finding that significant amounts of nitrogen can be dissolved in the extremely cold liquid methane that rains from the skies and collects in rivers, lakes and seas. They demonstrated that slight changes in temperature, air pressure or composition can cause the nitrogen to rapidly separate out of solution, like the fizz that results when opening a bottle of carbonated soda.

These results might help explain the mysterious islands that seem to appear and disappear and then reappear in Titan’s lakes. Rather than islands, they might be patches of nitrogen bubbles.

Minneapolis: another American city destroyed by Democrats

Link here. Democrats will see this as a partisan attack. It really isn’t. It is instead another attempt to point out the stark fact that the leftwing policies put forth by the Democratic Party in the past half century have been routinely disastrous.

But by 1988, then-mayor Donald Fraser—a member of the DFLP—had grown troubled by the stark contrast he saw between the majority of his city and who were thriving economically, and a number of African-American neighborhoods where crime, teenage pregnancy, and welfare dependency were experiencing a growth spurt. Taking a page out of the same playbook other big city Democrat mayors were using, Fraser believed that the cure was redistribution of income. He decided to revamp the way in which social-welfare expenditures were allocated and believed, specifically, that federal and local agencies needed to focus more of their resources on the economic problems confronting unwed mothers (who were disproportionately black) and their children.



Fraser’s successors as mayors of Minneapolis—Sharon Sayles Belton (1994-2001), R.T. Rybak (2002-2013), and Betsy Hodges (2014-present)—have shared this same core belief in the importance of massive public expenditures on social-welfare programs and wealth-redistribution initiatives.

The result has been disastrous. As of 2015, the poverty rate in Minneapolis was 25.3%, nearly twice the 14% statewide rate for Minnesota and the 14.3% rate for the United States as a whole. In 2010, a study of 142 metro areas in Minnesota found that only 15 bore a heavier property-tax burden than Minneapolis, and that was before the city raised its property taxes by 4.7% in 2011.

More recently, Minneapolis property taxes increased by 3.4% in 2016, and by a crippling 5.5% in 2017.

 Notwithstanding the growth in revenues generated by these taxes, the government of Minneapolis has been incapable of balancing its budget. In 2015, for example, the Minneapolis Public Housing Authority’s budget included $84 million in federal subsidies and grants. In 2017, the Metropolitan Council—which describes itself as “the regional policy-making body, planning agency, and provider of essential services for the Twin Cities metropolitan region”—received $91 million in federal funding. That same year, the Minneapolis Public Schools operated with a budget deficit of nearly $17 million.



This pattern has repeated itself throughout the United States. For the past half century almost every urban area has been dominated politically by Democrats. In that same time period, those urban areas have seen a distinct worsening of their economic situation. Even as these American cities have imposed a higher and higher tax burden on their successful citizens, they have seen higher and higher deficits. At the same time, poverty and economic failure has increased.

The important thing to note here is that the policies of the Democratic Party are a failure. Since that party seems incapable of changing those policies, it is essential that voters stop voting for it, either to force a change within that party or to remove that party from any position of power. Those are our choices, if we wish to improve the future of the United States.

House leans to less regulation of commercial space

During a hearing on March 8 of the House subcommittee on space the representatives overall pushed for less regulation of commercial space activities.

The overall problem was once again dealing with the Outer Space Treaty:

At a March 8 hearing of the subcommittee, members and witnesses grappled with the issue of how the government should oversee emerging commercial space activities in order to comply with obligations to the Outer Space Treaty, including whether such oversight is, in fact, required. Such “authorization and continuing supervision,” as specified in Article 6 of the treaty, is handled today by various agencies for commercial communications and remote sensing satellites and for launch. It’s less clear who would regulate new activities, ranging from commercial lunar landers to satellite servicing efforts, creating uncertainty in industry about who, if anyone, could provide that authorization and continuing supervision.

An April 2016 report delivered to Congress by the White House’s Office of Science and Technology Policy, required by Section 108 of the Commercial Space Launch Competitiveness Act of 2015, recommended what it called a “mission authorization” approach for providing that oversight. This approach would be modeled on the payload reviews performed by the Federal Aviation Administration during the launch licensing process, including an interagency review of proposed missions. While the mission authorization concept had won support from many in industry, as well as the FAA and some members of Congress, a change of administrations and its approach to regulation has emboldened some who want to limit industry regulation.

“Unfortunately, the Obama administration issued a report last year that called for expansive regulations over all types of private space activities,” said Rep. Lamar Smith (R-Texas), chairman of the House Science Committee, at the hearing. He cited a “crisis of overregulation” in general as a reason to oppose the previous administration’s proposal.

The House members and the witnesses apparently rejected the regulatory proposals that had been put forth by the Obama administration, and were instead searching for ways to limit the amount of regulation required under the Outer Space Treaty.

I say, dump the treaty. Nothing in it helps the development of space by private individuals or companies. Everything in it encourages bureaucracy and the limitation of private property.

SpaceX wins another Air Force launch contract

The competition heats up: SpaceX has been awarded a $96.5 million contract to launch an Air Force GPS satellite.

This price is about $14 million more than the last SpaceX Air Force launch contract. That’s probably because SpaceX was trying to undercut ULA’s price by as little as possible so that they could increase their profit. Until there are others in the business who can compete with SpaceX’s prices, the company is sitting pretty in any competitive bidding situation. Their costs are less, so they can always beat everyone else’s prices, while maximizing their profits.

Ukraine-Canadian partnership to launch from Nova Scotia

The competition heats up: A new launch company based in Canada and using a Ukrainian-made rocket called the Cyclone-4M has chosen as its launch site a location in Nova Scotia.

The rocket appears to be a variation of the Ukrainian Tsiklon-4 rocket, and would make this company competitive and in fact more capable than India’s smaller PSLV rocket that recently put 100 smallsats into orbit.

Engineer invents teabag dunking machine

Rube Goldberg lives! I don’t know why, but an engineer has invented a machine that can dunk his teabag automatically.

The teabag is hooked onto a crank and kept in position with a piston-like mechanism so that it’s moved up and down over a strategically-placed mug of hot water. The crank is mounted to copper tubing and chained to a five sprocket cassette that in turn is chained to the shaded-pole motor. Dunking starts when a switch is flicked.

Be sure to watch the video at the link.

University removes weight scale from gym because TRIGGER

The coming dark age: Carleton University in Canada has decided to remove the weight scale in their gym because someone complained it “triggered” them.

Several students were completely onboard with the decision. Per the Charlatan, one student named Samar El-Faki said it was a good call that accommodated people with eating disorders. “Scales are very triggering,” she said. “I think people are being insensitive because they simply don’t understand. They think eating disorders are a choice when they are actually a serious illness.”

But she was in the minority, as many other students criticized the college for pandering to special snowflakes. “Next it will be the mirrors,” wrote another student on Facebook.

This is essentially the heckler’s veto. One person complains that they don’t like something, and the university bows to that one person’s wishes, banning something that everyone else uses and needs. More important, the whiner had a very easy solution that would not have required removal of the scale: Don’t step on the damned scale and it won’t bother you! That they didn’t take that route illustrates that power and intimidation was their real game.

I should add that even though the university is considering bringing the scale back because of the criticism it has faced for removing it, that its officials were willing to bow so easily to this heckler’s veto suggests this is not a good university to send your kids.

But, then, what university today is a good place? They all seem infested with these fascists who have the support and aid of the administrations in power.

Microsoft inserts ads in Windows 10

Why I use Linux, part 5,234,657: Microsoft is now inserting advertisements for its software throughout its Windows 10 operating system.

Microsoft has taken the next step in pushing advertising on customers of its Windows 10 operating system, with users reporting an advertisement for Microsoft OneDrive now appearing in their File Explorer.

Windows 10 has been repeatedly reprimanded by technology journalists over the past year for the increasing amounts of advertising that are baked into the system. Advertisements in various forms have appeared in the Start menu, the lock screen, the taskbar, in the Windows Store, and various other areas. This seems to be the first time that users are noticing them in the File Explorer, the application that allows users to look through their documents and applications on their computer.

As I have been saying for years, dump Windows. It invades your privacy, provides you bad service while crashing at the worst possible moments. There are alternatives. I have been using Linux now for more than a decade, and it hasn’t held me back. Here again are the links to James Stephens’ series on Behind the Black for Getting and Installing Linux:

New York dumps literacy tests for teachers

The coming dark age: In the name of political correctness and ethnic diversity, New York has decided to eliminate literacy tests for its teachers.

It seems that about one third fewer black and hispanic applicants passed the test.

“We want high standards, without a doubt. Not every given test is going to get us there,” Pace University professor Leslie Soodak told the AP. Soodak was a member of the task force that advocated abandoning literacy tests for teachers.

“Having a white workforce really doesn’t match our student body anymore,” Soodak added. [emphasis mine]

Having an uneducated workforce that can’t read, that’s okay however.

Parachute tests for Boeing Starliner

Boeing’s Starliner spacecraft has successfully completed a parachute test at New Mexico’s Spaceport America.

Uniquely, this test wasn’t conducted via the use of a helicopter of an aircraft – as seen with other vehicles, such as the Orion spacecraft. Boeing was not able to fit the Starliner test article into the hold of a C-130 or C-17 aircraft, so they instead used a 1.3-million-cubic-foot balloon, which is able to lift the capsule to its intended altitude.

The test went well, with Starliner released from the balloon, deploying two drogue parachutes at 28,000 feet to stabilize the spacecraft, then its pilot parachutes at 12,000 feet. The main parachutes followed at 8,000 feet above the ground prior to the jettison of the spacecraft’s base heat shield at 4,500 feet. Finally, the spacecraft successfully touched down.

The article once again makes note of NASA’s fake concern over the Atlas 5 rocket. The concern isn’t that the rocket isn’t reliable. The concern is that Boeing hasn’t yet gotten NASA’s certification that it is reliable. In other words, because NASA hasn’t signed a piece of paper stating the obvious fact that the Atlas 5 is safe, Boeing’s Starliner cannot be considered safe.

Decision on new Orbital ATK rocket expected in 2018

The competition heats up? Orbital ATK says it will decide whether it will introduce a new commercial rocket sometime in early 2018.

Orbital ATK has released few details about what is known only as its “Next-Generation Launcher.” The vehicle would use solid-fuel lower stages based on space shuttle solid rocket motor segments developed by the company, as well as solid strap-on boosters. A liquid-oxygen, liquid-hydrogen upper stage would use a version of Blue Origin’s BE-3 engine that company is currently flying on its New Shepard suborbital vehicle.

The rocket’s design has at least superficial similarities to a vehicle concept called Liberty that ATK proposed prior to its merger with Orbital Sciences Corporation. Liberty, with a five-segment shuttle solid rocket booster first stage and a second stage derived from the Ariane 5 core stage provided by Astrium, was itself a commercial spinoff of the cancelled Ares 1 rocket from NASA’s Constellation program. ATK proposed Liberty for NASA’s commercial crew program but failed to win funding.

The decision itself will be based on whether the Air Force remains interested. At the present time the Air Force is investing about half the capital required to develop the rocket. If the Air Force backs out, Orbital ATK will decide against the rocket. If the Air Force support remains firm, they will go ahead with development. Essentially, this story is Orbital ATK lobbying to keep the Air Force support going.

Sessions asks all remaining attorneys appointed by Obama to resign

Better late than never: Attorney General Jeff Sessions today asked the attorneys appointed by Obama that remain in the Justice Department to resign.

The article says that this is standard operating procedure, but that is not entirely true. Until Clinton was president most Justice Department attorneys were long term prosecutors who remained in office from administration to administration. They were not partisan appointees. Clinton changed that when he fired them all. I do not know if Bush followed through and did the same thing, but I tend to doubt it. Obama however would have certainly fired any Bush appointees when he took office.

What makes this significant is that it appears to be the first time that a Republican president since Clinton is fighting back and cleaning house of Democratic appointees.

Saturn’s weird moon Pan

Pan

New images from Cassini have provided scientists their first sharp images of Saturn’s moon Pan, and what those images show is something really weird. The image on the right is only one sample, with the link providing more.

Pan orbits in a gap between two rings, and the ridge might have accumulated from material from those rings. Then again, maybe not. It will take more data to I think completely unravel how this moon got to look like it does.

Congress micromanages rocket development at ULA

Corrupt Congress: Even though ULA favors Blue Origin’s BE-4 engine for its Vulcan rocket, various elected officials in Alabama are pushing the company to use Aeroject Rocketdyne’s AR-4 engine instead.

At the end of February, two US representatives, Mike Rogers of Alabama [Republican] and Mac Thornberry of Texas [Republican], decided to push a little harder. On February 28, they sent a letter to Lisa Disbrow, the acting secretary of the US Air Force, and James MacStravic, who is performing the duties of the undersecretary of defense for acquisition, technology, and logistics. In addition to reiterating a desire that ULA continue to fly a second rocket, the Delta IV Heavy, the letter urges the Pentagon officials to be skeptical about the BE-4 engine.

“The United States Government (USG) must have a hands-on, decision-making role… in any decision made by United Launch Alliance to down-select engines on its proposed Vulcan space launch system, especially where one of the technologies is unproven at the required size and power,” the letter states. “If ULA plans on requesting hundreds of millions of dollars from the USG for development of its launch vehicle and associated infrastructure, then it is not only appropriate but required that the USG have a significant role in the decision-making concerning the vehicle.” The letter then goes on to say the Air Force should not give any additional funding to ULA, other than for current launch vehicles, until the company provides “full access, oversight of, and approval rights over decision-making” in its choice of contractors for the engines on Vulcan.

The article also mentions porkmaster Senator Richard Shelby (R-Alabama), who also favors Aerojet Rocketdyne because they say they will build it in Alabama. Note also that these elected officials are not only trying to pick the winner in the private competition between these two rocket engines, they also want to force ULA to keep using the Delta rocket, even though it is very expensive and not competitive with the newer rockets being developed by other companies. And their only reason for doing so is because they provide jobs for their districts.

This one story illustrates perfectly the corruption that permeates both parties in Congress. While it is more likely that Democrats will play this pork game, there are plenty of corrupt Republicans who play it as well. These petty dictators all think they have the right to interfere in the private efforts of Americans, whether it involves building a new rocket or buying health insurance. And all we get from this is a poorer nation and a bankrupt federal government.

Stratolaunch to fly in 2017?

The competition heats up: In an interview Paul Allen has revealed that he hopes to begin flight tests of his gigantic Stratolaunch airplane, the largest ever built, later this year.

No word on the rocket that this air-launched system would launch, however. In fact, it appears that no one seems interested in providing one. This could change once the plane is flying.
