Seven unjustified school suspensions

6:51 pm

Seven school suspensions that were insane and completely unjustified.

I’ve posted about most of these stories previously, but it is important to read about them again to see how completely ridiculous and oppressive they were. Each one of these actions was a good reason for everyone to pull their kids from these public schools, especially when the school officials who perpetrated these obscenities were not fired.

The first and third were especially egregious, but the third illustrates how best to combat the schools when they act this way.

Fourteen year old Jared Marcum wore a NRA “Protect Your Rights” t-shirt to school with a hunting rifle on it. Despite the fact that the shirt didn’t violate the school’s dress code, a screaming teacher demanded that he turn the shirt inside out. Marcum was then removed from class, suspended, arrested, and faced a year in jail for “obstructing an officer” because he wouldn’t stop protesting his innocence while he was being hauled away. In this case, 100 kids wore the same shirts to school as part of a protest without being challenged and the family lawyered up and got the charges dropped. [emphasis mine]

If one student is suspended for making his pop tart look like a gun, every student in the school should do the same. If one student is suspended for innocently using the word “gun” in conversation, then every student in the school should use the word repeatedly in conversation. If students and parents inundate the school with more examples of the behavior the school was trying to ban, the schools stop this insanity very quickly.

ISIS demands a Jewish genocide

12:09 pm

The religion of peace: ISIS supporters are now demanding a new Jewish holocaust.

Facts remain facts. The world of Islam is poor, ignorant, bigoted, violent, and oppressive. Where there is wealth, such as in the Middle East, it is fueled entirely by oil that was found by Western capitalist companies and pumped to the surface using Western-developed technology. Without that help, the oil would still be underground and these Islamic countries would still be poor.

The oppressive nature of Islam, however, remains obvious and widespread. If we are intellectually honest we must ask: Why is that? What is it about Islam that results in this consistent cultural and social failure? An open-minded look at the language of the Koran and the history of this religion will give you a straight-forward answer, and that answer is not a pleasant one.

That the American intellectual community and many American politicians from both parties seem unwilling to take this hard look at Islam says a great deal about their lack of intellectual honesty. It also tells us something about their own attitude towards oppression. Maybe they don’t dislike tyranny that so much.

Plastic bags do not kill birds and fill the oceans

9:49 am

Another environmental claim turns out to be vastly exaggerated: The scientist who claimed that islands of plastic bags were filling the oceans has found that his claim was bogus.

The scientist whose findings environmentalists used to shame us into bringing our own reusable bags to the grocery store now says that his estimate of one million tons of plastic floating in the ocean may have been off by a factor of perhaps 143. His latest estimate ranges from 7,000 to 35,000 tons, and even most of that has biodegraded into granules. …

Also doubtful: The environmentalist claim that 1.5 million marine animals choke to death each year on plastic bags that ran away from home for a life at sea. They’ve revised their estimates downward to 6.6 percent of that, but even the new figure has no empirical support.

But remember, Barack Obama says the science is settled, and that anyone who questions him or expresses any doubt is the equivalent of a Holocaust denier.

How beautiful we were.

How beautiful we were.

An epitaph for American on its birthday.

And on its birthday, we should all make it a point to reread this document. Key quote:

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.–That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, –That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.

Space junk damages ISS coolant radiator?

9:09 am

According to the Russian Interfax news agency, a piece of space junk has hit a coolant radiator on the U.S. portion of ISS.

The source says that no coolant has escaped from the system and that NASA engineers are analyzing images to assess the damage.

Readers should be aware that I have tried without success to find the NASA website the story claims is the source for this information. Moreover, this story is reported nowhere in the U.S. press, and it is strange for a NASA website to report something like this and it not be quickly picked up by the U.S. press.

Thus, I am not entirely convinced yet that this story is accurate.

Update: a commenter below has provided this link to a subsequent post at nasaspaceflight about the impact.

Corvette Museum preserves sinkhole

10:28 pm

Turning lemons into lemonade: The sinkhole that swallowed eight prized cars at the National Corvette Museum in Kentucky in February has become such an attraction that the museum intends to preserve it.

Attendance was up nearly 60 percent from March to the start of this week, compared to the year-ago period, museum officials said. Sign-ups for museum memberships are up sharply, as are merchandise and cafe sales at the museum. The museum sells sinkhole-related shirts, post cards and prints.

Museum board members considered three options for the sinkhole: fill it in, preserve the entire sinkhole or keep a portion of it. They opted to maintain about half the 40-foot-wide, 60-foot-deep sinkhole, Strode said. There’s a “strong probability” that one or two of the damaged cars will be put back in the hole, he said.

ISEE-3 fires its thrusters for the first time since 1987.

4:57 pm

The private team resurrecting the 1970s space probe ISEE-3 successfully fired its thrusters for the first time since 1987.

It took several attempts and days to perform the roll maneuver because ISEE-3 was not responding to test commands. But this time, controllers got in touch. They increased the roll rate from 19.16 revolutions per minute to 19.76 RPM, putting it within mission specifications for trajectory corrections.

The spacecraft is now prepped for the big burn that will change its trajectory.

Two exoplanets disappear

4:53 pm

The uncertainty of science: Two exoplanets orbiting Gliese 581, both thought to be in the habitable zone, have now been proven to not even exist.

“We’ve proven that some of the controversial signals from Gliese 581 don’t come from two proposed Goldilocks planets, but instead are coming from activity within the star itself masquerading as planets,” lead study author Paul Robertson, an astronomer at Pennsylvania State University in University Park, told Space.com.

This result should serve as a strong reminder: Though it is likely that many if not most of the so far discovered exoplanets are real, it is also likely that many will turn out to be false positives. We won’t have solid real knowledge about them until we can actually get a close look at them, which will require far better telescopes in space, and maybe even interstellar missions to them.

Telescope teamwork produces spectacular galaxy image

11:55 am

M106

Combining images from a host of space and ground-based telescopes, astronomers have created a spectacular image of the galaxy M106.

This galactic fireworks display is taking place in NGC 4258 (also known as M106), a spiral galaxy like the Milky Way. This galaxy is famous, however, for something that our Galaxy doesn’t have – two extra spiral arms that glow in X-ray, optical, and radio light. These features, or anomalous arms, are not aligned with the plane of the galaxy, but instead intersect with it.

The anomalous arms are seen in this new composite image of NGC 4258, where X-rays from NASA’s Chandra X-ray Observatory are blue, radio data from the NSF’s Karl Jansky Very Large Array are purple, optical data from NASA’s Hubble Space Telescope are yellow and blue, and infrared data from NASA’s Spitzer Space Telescope are red.

A new study of these anomalous arms made with Spitzer shows that shock waves, similar to sonic booms from supersonic planes, are heating large amounts of gas – equivalent to about 10 million Suns. What is generating these shock waves? Radio data shows that the supermassive black hole at the center of NGC 4258 is producing powerful jets of high-energy particles. Researchers thinkthat these jets strike the disk of the galaxy and generate shock waves. These shock waves, in turn, heat some of the gas – composed mainly of hydrogen molecules – to thousands of degrees.

The astronomers also used the Herschel Space Observatory to confirm the data from Spitzer.

Newly discovered dinosaur tracks

9:59 am

A cluster of dinosaur tracks discovered recently in Alaska has revealed to paleontologists a wealth of new information about their behavior.

The thousands of impressions, created on a 180-meter-long portion of near-coastal flood plain, today pepper a steep mountainside. Most of the tracks, made somewhere between 69 million and 72 million years ago, were left by hadrosaurs, commonly known as duck-billed dinosaurs (the crested creatures in this artist’s representation).

The consistent and excellent preservation of tracks suggests all the footprints were created within a short time period. Varying in width from 8 to 64 centimeters, the footprints cluster within four distinct size ranges, which researchers suggest represent specific age groups within a multigenerational herd. About 84% of the tracks were made by adult and near-adult hadrosaurs and 13% by young presumed to be less than 1 year old. A mere 3% of the tracks represent juvenile hadrosaurs, a rarity that strongly suggests the young of this species experienced a rapid growth spurt and therefore spent only a short time at this vulnerable size, the researchers report online this week in Geology.

Gigantic underground trampoline about to open

9:52 am

Want to have some fun? An amusement park in Northern Wales is about to open a gigantic underground trampoline ride to the public..

Battle Below is located deep within a 100 ft (30.5 m) deep and 60 ft (18.3 m) wide disused mine. The new site features three large trampolines stretching across the cave-like mine walls and are positioned at varying heights. The trampolines are linked together by 60 ft (18.3 m) slides and a spiraling staircase. Adding to the atmosphere, multi-colored LED lights have been installed throughout the mine, which project onto the walls of the cavern.

It took over a kilometer of nett and 4,500 man hours to complete the underground trampolines, which can accommodate 100 bouncing visitors at a time. Patrons are required to wear protective gear, including overalls and a helmet before gaining access to the site via an old mining train. They’re also encouraged to bounce as high as they dare, potentially reaching a maximum height of 80 ft (24 m).

Bounce Below opens on July 4, with tickets starting from £15 (about US$25) per person.

NASA and Boeing finalize contract to build the SLS rocket

3:37 pm

NASA and Boeing today signed a $2.8 billion contract for Boeing to build the core stage of the SLS rocket

Scheduled for its initial test flight in 2017, the SLS is designed to be flexible and evolvable to meet a variety of crew and cargo mission needs. The initial flight-test configuration will provide a 77-ton capacity, and the final evolved two-stage configuration will provide a lift capability of more than 143 tons.

It would be nice for the U.S. to have this heavy-lift rocket, but I fully expect the funds to run out immediately after it makes its inaugural flight, despite the wonderful pork it provides to so many Congressional districts. It just costs too much per launch.

Russia abandons Sea Launch

3:31 pm

Running from competition: The Russian space agency Roskosmos has decided not to spend the money necessary to buy Sea Launch and make it part of its consolidated United Rocket and Space Corporation (URSC).

Part of the reason the Russians are abandoning Sea Launch is that the rocket the ocean-going platform uses is the Ukrainian-built Zenit rocket, and Russia wants URSC to a wholly Russian operation. Rather than partner with Ukraine for profit, they will let the business die.

SpaceX’s Falcon Heavy rocket gets a customer

3:22 pm

The competition heats up: The commercial satellite company Inmarsat has booked SpaceX’s Falcon Heavy rocket for one firm launch and two additional options.

The firm contract is for the launch, scheduled perhaps aggressively for late 2016, of a satellite being built for both Inmarsat and Arabsat of Riyadh, Saudi Arabia. Arabsat will use the satellite for conventional telecommunications services for its wholly owned Hellas-Sat fleet operator of Greece. The Inmarsat payload uses S-band to provide mobile communications in Europe as part of a satellite-terrestrial broadband network, which is a new business line for Inmarsat.

Inmarsat’s launch contract is for a rocket that has not even yet been tested once, which tells us something about the faith they have in SpaceX. While I would be shocked if they didn’t have an option to pull out should there be significant delays or problems in launching Falcon Heavy, that they are willing to commit to it now is a convincing endorsement of SpaceX.

FIRE sues to end university speech codes

1:30 pm

Pushback: The Foundation for Individual Rights in Education (FIRE) today filed lawsuits against the speech codes at four universities.

Read the article. The specific examples are quite oppressive. For example:

At Citrus College in California, student Vincenzo Sinapi-Riddle is challenging three unconstitutional policies, including a free speech zone that the school already agreed to abolish after a 2003 lawsuit. Not only did Citrus College reinstitute its “Free Speech Area,” comprising a miniscule 1.37% of campus, but it also requires student organizations to undergo a two-week approval process for any expressive activity.
