Florida school district threatens homeschool parents with arrest

11:40 am

Fascists: A Florida school district is threatening to arrest and prosecute homeschooling parents if they do not register their children for public or private school immediately.

This threat was issued despite the fact that state law does not require such registration. The home-schoolers plan to attend the next school board meeting on November 17. That should be another interesting school board meeting.

Decline to solar minimum continues

11:26 am

It’s that time again buckos! On Monday NOAA posted its monthly update of the solar cycle, showing the Sun’s sunspot activity in October. As I have done every month since 2010, I am posting it here, with annotations to give it context.

The decline in sunspot continue steadily, matching the red prediction curve except that, as it has for this entire solar maximum, the number of sunspots continues to be less than expected. Not only did the ramp up start later and not quite reach the levels predicted, the ramp down started early. Overall, this now ending solar maximum is the weakest in a century. The big question remains: Is the Sun about to head into its first Grand Minimum since the 1600s, or is this weak maximum a one-time event to be followed by stronger activity in later cycles.

No matter what anyone tells you, no one knows.

October 2015 Solar Cycle graph

The graph above has been modified to show the predictions of the solar science community. The green curves show the community’s two original predictions from April 2007, with half the scientists predicting a very strong maximum and half predicting a weak one. The red curve is their revised May 2009 prediction.

Vizio smart televisions watch YOU

10:12 am

If you are going to buy a smart television, don’t buy one by Vizio, as they by default track your viewing and provide the information to advertisers.

The feature, “Smart Interactivity,” is already turned on as a default setting for millions of people who have purchased the device. Viewers are able to turn off the setting, that is, if they know it even exists. “Non-personal identifiable information may be shared with select partners… to permit these companies to make, for example, better-informed decisions regarding content production, programming and advertising,” Vizio said in a statement.

Vizio seems to be taking a new approach by tracking viewers by default, while competitors like San Jose-based Samsung or LG Electronics leave it to customers to turn the setting on. Vizio’s sharing with advertisers also reportedly lets them target devices like your phone, which other companies do not.

Somehow this seems to be a direct violation of privacy, which also might be quite illegal.

Student reporter files complaint against teacher

10:04 am

Pushback: The student reporter who was pushed and threatened with violence by a professor at the University of Missouri has now filed a police complaint.

The student, Mark Schierbecker, had been videotaping students and teachers as they acted to eject an ESPN photographer from a so-called “free-speech zone” on the campus. The teacher, Melissa Click, then tried to grab Schierbecker’s camera and threatened him with violence if he didn’t leave also. You can watch the video below the fold, with the confrontation in question beginning at 7:00 minutes. Click appears to be in charge of the mob in its effort to eject all reporters from the area. Near the end of the video she circles the area, yelling “Don’t let those reporters in!”

Though Click has resigned from one position at the school, she remains a professor of communications. That she does not really regret what she did is illustrated by this quote:

Schierbecker said he met with Click at her office on Tuesday, but that he found her apology “lacking.” He said that he’s made further attempts to contact Click to speak to her about his grievances with her, but she has refused to engage him. “I am just left with the feeling that she doesn’t care,” Schierbecker told USA TODAY.

More people have to file complaints like this when they are attacked by the leftist fascists on campus. Maybe then we might be able stop these bullies from running things and regain some civility in our schools.

More mob college protests, now in New York

9:40 am

The mob moves on: Fascist bigots at Ithaca State College are protesting and demanding the resignation of the school’s president because he doesn’t favor blacks.

The protest, which began around 1:30 p.m. and attracted at least 750 people, was in response to what organizers said were a series of incidents that demonstrated cultural insensitivity and exclusion of certain groups. Nigel Cyril, a junior at Ithaca College who is studying emerging media and Italian, said he’s never had a black professor. He and other called on college president Tom Rochon to resign. “I’ve never had a black professor,” said junior Nigel Cyril, who was holding a sign asking the students to vote no confidence in the president. “I do feel the racial tensions in this college. I’ve been pretty quiet so far, but it’s time for (the president) to do something.” [emphasis mine]

Other than the fact that this idiot student has never had a black teacher, the article does not provide any other examples of black oppression. However, it does provide us plenty of examples of blacks who are outright bigoted against whites, or in fact any other race except blacks.

Based on the article, I also expect this college president to cave, and possibly resign.

Bibles banned from school libraries in Tennessee

9:19 am

Fascists: Because of a complaint, a Tennessee school administrator has banned Gideon Bibles from providing free bibles to the school’s libraries.

Superintendent Jennifer Terry would not elaborate on the complaints made. In a statement to Channel 3 News, she said the school system will no longer allow any religious group or material to be distributed. “Bledsoe County Schools do not allow the distribution of religious materials from any religious groups. The distribution of religious materials in a public school is in violation of constitutional provisions and well established federal and state laws and precedence,” Jennifer Terry, Director of Schools in Bledsoe County

This is insane. The government is not establishing a state religion by accepting free bibles from private American citizens for its libraries. It is a library, where books are made available to read. If the school can get some of those books free they should take them. To suggest that a government-run library can’t contain any religious books is the height of stupidity.

The article suggests that the community plans to protest this at the next school board meeting. It will be interesting to see what happens.

Dubai to use jetpacks to fight fires

8:59 am

Buck Rogers lives! In order to better fight fires among its many high skyscrapers, Dubai officials have purchased 20 jetpacks for use by its firefighters.

Martin Jetpacks have been developed with first responder use in mind. They can be flown by a pilot or via remote control, take off and land vertically, operate in confined spaces (such as close to or between buildings or near trees) and carry commercial payloads of up to 120 kg (265 lb). This functionality means the Jetpacks can provide a variety of first response services. For example, they can be used for surveillance or observation (such as to determine the focus of a fire), transporting equipment to where it is required, rescuing individuals or deploying specialist teams.

Though it sounds cool, remotely controlled drones would make more sense for most of these tasks. The jetpacks might be useful for getting crews in and out of difficult high locations, as well as possibly rescuing trapped victims, but to make this practical will require significant training, something that I don’t see as realistic.

Failed GPS satellites to test Einstein’s theory

8:52 am

Making lemonade from lemons: Scientists are going to repurpose two GPS satellites — launched into wrong orbits and thus useless for GPS — to conduct a test of Einstein’s theory of general relativity.

The satellites, operated by the European Space Agency (ESA), were mislaunched last year by a Russian Soyuz rocket that put them into elliptical, rather than circular, orbits. This left them unfit for their intended use as part of a European global-navigation system called Galileo.

But the two crafts still have atomic clocks on board. According to general relativity, the clocks’ ‘ticking’ should slow down as the satellites move closer to Earth in their wonky orbits, because the heavy planet’s gravity bends the fabric of space-time. The clocks should then speed up as the crafts recede.

On 9 November, ESA announced that teams at Germany’s Center of Applied Space Technology and Microgravity (ZARM) in Bremen and the department of Time–Space Reference Systems at the Paris Observatory will now track this rise and fall. By comparing the speed of the clocks’ ticking with the crafts’ known altitudes — pinpointed within a few centimetres by monitoring stations on the ground, which bounce lasers off the satellites — the teams can test the accuracy of Einstein’s theory.

There actually is little uncertainty here. No one expects this experiment to disprove Einstein’s theory, but the failed spacecraft provide a great opportunity to measure things at an accuracy never previously attempted, which in turn will help improve future GPS design.

Planning the coming end of Rosetta

8:44 am

The scientists and engineers operating Rosetta have begun planning the mission’s spectacular finale, when they will spend several months orbiting within six miles of Comet 67P/C-G’s surface before very gently crashing the spacecraft on the surface.

Because of many factors, Rosetta is not expected to survive the impact, no matter how gently it lands. However, the data it will send back in its final months as it makes tighter and tighter orbits should be well worthwhile.

In related news, the science team has released an animation, posted below the fold, of their re-creation of the flight and crash landing of Philae on the comet.

Ground-breaking for the Giant Magellan Telescope in Chile

10:07 pm

Even as construction of the Thirty Meter Telescope (TMT) in Hawaii remains stalled because of protesters, ground has now been broken in Chile for the construction of the Giant Magellan Telescope (GMT).

The unique design of the telescope combines seven of the largest mirrors that can be manufactured, each 8.4 meters (27 feet) across, to create a single telescope effectively 25 meters or 85 feet in diameter. The giant mirrors are being developed at the University of Arizona’s Richard F. Caris Mirror Laboratory. Each mirror must be polished to an accuracy of 25 nanometers or one millionth of an inch.

One giant mirror has been polished to meet its exacting specifications. Three others are being processed, and production of the additional mirrors will be started at the rate of one per year. The telescope will begin early operations with these first mirrors in 2021, and the telescope is expected to reach full operational capacity within the next decade.

Assuming TMT ever gets built, it will, unlike GMT, be made up of many small segments.

Earth-sized exoplanet found only 39 light years away

10:01 pm

Worlds without end: Astronomers have discovered an exoplanet only slightly bigger then the Earth, and it’s only 39 light years away.

Berta-Thompson and the others estimate that GJ 1132b has a diameter of about 9,200 miles, slightly bigger than Earth. Its mass, however, is thought to be 60 percent greater than Earth’s. Its home star — GJ 1132 — is a red dwarf one-fifth the size of our sun. The planet circles every 1.6 days from just 1.4 million miles out, thus the heat wave. A slight dip in the starlight every 1.6 days was the giveaway for the observing team. “Our ultimate goal is to find a twin Earth,” said astronomer David Charbonneau of the Harvard-Smithsonian Center for Astrophysics, one of the authors, “but along the way we’ve found a twin Venus.”

Stars in the Milky Way so old they predate it

5:00 pm

Astronomers have discovered stars inside the Milky Way that are thought to be so old that they were formed prior to the existence of the galaxy, and that the Milky Way formed around them.

The stars, found near the centre of the Milky Way, are surprisingly pure but contain material from an even earlier star, which died in an enormous explosion called a hypernova. “These pristine stars are among the oldest surviving stars in the Universe, and certainly the oldest stars we have ever seen,” said Louise Howes, lead author of the study published in the latest issue of Nature. “These stars formed before the Milky Way, and the galaxy formed around them,” said Ms Howes, a PhD student at the ANU Research School of Astronomy and Astrophysics.

Not surprisingly, the discovery challenges theories that describe the early universe.

SpaceX successfully tests its Dragon capsule abort rocket thrusters

10:39 am

The competition heats up: SpaceX has successfully tested its abort rocket thrusters that will be used to speed a Dragon capsule away from any rocket during a failed launch.

Named SuperDracos, the engines are arranged in four pairs – SpaceX calls them ‘jetpacks’ – integrated around the outside of the Crew Dragon spacecraft. Firing all at once, the eight engines produce 120,000 pounds of thrust – enough power to accelerate a Crew Dragon from zero to 100 mph in 1.2 seconds. In the unlikely event of an emergency, that power means the ability to lift the crew a safe distance off the launch pad or far away from a booster failing on the way to orbit. That capability was demonstrated earlier this year in a pad abort test that confirmed the SuperDraco design in a flight-like condition.

A normal launch of the Crew Dragon atop a Falcon 9 rocket would not offer the SuperDracos anything to do during the mission since their only responsibility is to fire in an emergency to rescue the crew onboard. Eventually, SpaceX plans to use the SuperDracos in the place of a parachute during landing.

Congress revises law governing commercial space

10:32 am

The competition heats up? Congress this week passed a revision to the Commercial Space Act that they claimed will help encourage the growth of the new industry.

According to the Senate press release, the bill does the following:

  • Extend the liability waiver for private space launches until 2023
  • Extend ISS operations until 2024
  • Establishes a legal right for U.S. companies to mine resources in space
  • Demands a new more streamlined framework for the government’s regulation of the industry

The last item is probably mostly blather, since a close look at the bill itself [pdf] reveals that most of these demands are merely requirements that the executive branch write a report. The odious rules that will allow the federal government to regulate and restrict the industry all remain. And even though the bill makes a big deal about establishing these regulations in concert with the industry itself, that only means that today’s players can use the government to make it difficult for new players to get started.

The claim that the bill also establishes “a legal right to resources a U.S. citizen may recover in space consistent with current law and international obligations of the United States,” as noted in the Senate press release, is a very big overstatement. The bill’s wording does nothing to get the U.S. out of the UN’s Outer Space Treaty, which forbids any person or nation from claiming ownership of territory in space. All the bill does is express the desire that American citizens should have the right to own what they mine, while at the same time stating that these resources will be “obtained in accordance with applicable law, including the international obligations of the United States.’’ In other words, the Outer Space Treaty still applies, and you can’t own it.

For what it’s worth, the bill also renames the FAA’s space regulatory agency from “The Office of Space Commercialization” to “The Office of Space Commerce.”

All in all, the bill’s most important overall accomplishment is that it strongly emphasizes and encourages the development of a private space industry, and tries to focus the government’s regulatory efforts in that direction. This ain’t perfect, but it could be considered a step in the right direction.

One more thing to note: Senator Ted Cruz (R-Texas) appears to have been a major player in getting this bill written and passed.

Another new American rocket engine tested successfully

9:58 am

The competition heats up: Sierra Nevada has successfully tested a new rocket engine, dubbed Vortex, specifically designed to fulfill a wide range of uses. From the press release:

These tests demonstrate the ability to transition use of different propellant combinations in the same core rocket engine design with slight changes to accommodate a specific combination of fuel and oxidizer, including propane and kerosene fuels with nitrous oxide (laughing gas) and liquid oxygen oxidizers. This latest development offers customers a suite of engines scalable to higher thrust levels and customer-selected fuel combinations from a single core rocket engine design. ORBITEC’s patented vortex rocket engines utilize a unique swirling propellant flow to naturally cool the engine walls, allowing for the development and manufacture of simpler, low-cost, light-weight and more robust rocket engine systems.

What strikes me about this is that, until SpaceX built its Merlin engine in the mid-2000s, it had been decades since the American aerospace industry had developed a new rocket engine. After the development of the shuttle’s main engines in the late 1970s nothing new was created for the rest of the 20th century. Since Merlin, however, we have seen a string of new engines from several different companies, suggesting that the new renaissance I wrote about back in 2005 is on-going and accelerating.

Time to shut the universities down?

9:16 am

Link here. The article first provides a nice summary of the insanity occurring at the University of Missouri, where students and teachers teamed up to force the resignation of two administrators, including the school’s president. Why did they do this?

Wolfe was targeted, as one protest group put it, because he was “‘not completely’ aware of systemic racism, sexism, and patriarchy on campus.” I love the “not completely.” It reminds me of the old rule about totalitarian revolutions: first, you go after the counter-revolutionaries, then you go after the insufficiently enthusiastic. So Wolfe had to be removed for failing to show immediate and total compliance toward their political agenda.

This reaction makes sense only as a raw power play, as student agitators demonstrating that they can get rid of anybody they want to, that they run this place.

The article then summarizes the same madness occurring at Yale, where students are demanding other administrators to resign because they had the nerve to defend the concept of free speech. The author then notes:

This is higher ed’s time for choosing. If this is the new purpose of the universities—to nurture a crop of activists trained at whipping up angry mobs, and a generation of college graduates conditioned to submit to those mobs—then there is no longer any purpose served by these institutions. There is certainly no justification for the outrageous claim they are making on the economic resources of the average family, who sends their kids to schools whose tuition has been inflated by decades of government subsidies.

The universities have done this to themselves. They created the whole phenomenon of modern identity politics and Politically Correct rules to limit speech. They have fostered a totalitarian microculture in which conformity to those rules is considered natural and expected. Now that system is starting to eat them alive, from elite universities like Yale, all the way down to, er, less-than-elite ones like Mizzou.

Mob rule cannot be tolerated by any democracy. If that is all tyhe universities are only going to teach, we then have to clean house.

David Arnold – Independence Day

6:01 pm

An evening pause: Vienna’s Radio Symphony Orchestra performs an excerpt of David Arnold’s soundtrack to the 1996 film Independence Day during the 2013 Hollywood in Vienna concert.

The film was incredibly silly, but fun nonetheless. The performance here captures some of that silliness, with the lighting and the smoke and the film clips. Also, the score’s use of a drum and flute in a short section near the middle is clearly intended to refer to the American Revolution, since in the movie the human race, led by Americans, conquers the aliens on the 4th of July, Independence Day..

Hat tip Danae.

Ice volcanoes, spinning moons, and more proof of geologic activity

3:28 pm

The New Horizons science team has released more results from the spacecraft’s July 14 fly-by, revealing the existence of what look like two giant ice volcanoes on Pluto, data that suggests the smaller moons spin like tops, and a census of Pluto’s craters that show them distributed very unevenly across the planet’s surface, suggesting that large parts of Pluto’s surface have been resurfaced and thus have been geologically active.

One discovery gleaned from the crater counts also challenges the most popular theory about the formation of objects in the Kuiper Belt.

Crater counts are giving the New Horizons team insight into the structure of the Kuiper Belt itself. The dearth of smaller craters across Pluto and its large moon Charon indicate that the Kuiper Belt likely had fewer smaller objects than some models had predicted. This leads New Horizons scientists to doubt a longstanding model that all Kuiper Belt objects formed by accumulating much smaller objects of less than a mile wide. The absence of small craters on Pluto and Charon support other models theorizing that Kuiper Belt objects tens of miles across may have formed directly, at their current—or close to current—size.

In fact, the evidence that many Kuiper Belt objects could have been “born large” has scientists excited that New Horizons’ next potential target – the 30-mile-wide (40-50 kilometer wide) KBO named 2014 MU69 – which may offer the first detailed look at just such a pristine, ancient building block of the solar system.

As always, the results here are significantly uncertain. They are giving us a glimpse into the geology of rocky planets far from stars, but only a glimpse. I guarantee that any theories formed from this data will be incomplete and will likely be proven wrong.

Republican claims of media bias supported by facts

8:42 am

Republican claims of media bias against conservatives is supported by new research that finds almost all journalists are Democratic and even donate money to Democrats.

[S]elf-proclaimed Democratic journalists outnumber Republicans by 4-to-1, according to research by Lars Willnat and David Weaver, professors of journalism at Indiana University. They found 28 percent of journalists call themselves Democrats, while just 7 percent call themselves Republicans — though both numbers are down from the 1970s. Those identifying as independent have grown.

Among Washington correspondents, the ones who dominate national political coverage, it’s even more skewed, said Tim Groseclose, author of “Left Turn: How Liberal Media Bias Distorts the American Mind.” More than 90 percent of D.C. journalists vote Democratic, with an even higher number giving to Democrats or liberal-leaning political action committees, the author said.

Having been a journalist for years, I can tell you that these numbers are accurate. And the increasing numbers of journalists who claim to be independent are in large number merely hardcore liberals who wish deniability if asked where they loyaties lie.

Why cold fusion and NASA’s EM Drive are most likely frauds

7:55 am

Link here. The writer does a nice job of explaining why impossible engines that appear to defy basic laws of physics are almost certainly incapable of doing what they promise, and are likely frauds.

An extraordinary result has to come with extraordinary evidence. When someone claims they have come up with something that can do something that engineers have been unable to do for centuries — since the very beginnings of the Industrial Age — I get very very suspicious, especially when their evidence is scanty and their data is not open for study.

More Mexico City traffic

Being in Mexico on a sightseeing trip, it is of course necessary to visit some famous churches as well as some Aztec ruins. On Thursday we headed out to do both, though we first had to slowly work our way through Mexico City’s never-ending bumper-to-bumper traffic to get where we were going.

When we got there what struck me the most about the two different tourist sites we visited was how much they resembled each other, despite being separated by almost 1500 years and completely different cultures and religious beliefs.

The old Basilica

Our first stop was to see the Basilica of the Guadalupe, located in northern Mexico City. To understand the significance of this site it is important to know the background. According to the story, which is not documented in any writings by clergy at that time, in 1531 native Juan Diego Cuauhtlatoatzin had a series of visions of the Virgin Mary, speaking to him in his native Aztec tongue. In those visions she told him that a church should be built at a specific spot in her honor. Initially his vision was rejected by the clergy when he told them about it. When the Virgin Mary began to work miracles, however, including having her vision miraculously appear on the front of Diego’s cloak, they came to accept the visions and proceeded to build that church as requested. The result was the Basilica, where Diego’s cloak is still housed and is on display for all to see. Juan Diego himself was canonized as a saint in 2002, the Catholic Church’s first indigenous saint from the New World.

The significance of these events for the Catholic Church in Latin America is hard to measure.

Two Mauna Kea protesters convicted but get minor sentences

8:29 am

Two protesters who blocked a road leading to the summit of Mauna Kea to block construction vehicles for the Thirty Meter Telescope (TMT) have been convicted of misdeamenors and given very minor sentences.

The state requested six months’ probation, and that they stay off Mauna Kea Access Road for the period of probation. Prosecutors also requested 72 hours of community service in lieu of a $500 fine. Fujiyoshi [one of the protesters] asked for a jail sentence instead of community service, and was sentenced to five days. He will serve one day in jail, with credit for time served; six months’ probation; and was ordered to remain off the access road. Lindsey-Kaapuni [the other protester] argued against probation, and was sentenced to 100 hours of community service.

The state here has no easy solution. If it demands severe punishment the press will make the protesters martyrs. If it lets them off then the protesters will know they can protest as much as they want and face no consequences.

Right now I do not see TMT ever getting built on Mauna Kea. I also see the slow removal of the telescopes already there to be certain, given time. The protesters are in control, and they oppose this search for knowledge about the universe.
