UC-Davis establishes rules to allow free speech

9:35 am

This could be a victory: A working group established by the administration of the University of California in Davis (UC-Davis) has recommended rules that will punish students who disrupt speakers and prevent them from speaking.

[T]he working group recommended the implementation of an “anti-disruption disciplinary rule” that would punish student who disrupt speakers, as was the case during Yiannopoulos’ visit to campus.“Although the determination of what constitutes disruption may be fact-specific and contextual in some cases and require the exercise of official discretion, the campus should clearly delineate disruptive behavior it deems presumptively unacceptable and provide clear notice to students engaging in such behavior that their conduct warrants a disciplinary response,” the working group explains.

Additionally, the report recommends regular “freedom of expression education events” to highlight the “values served by freedom of expression on a university campus.” Among such events, the working group suggests “interactive town halls and workshops” that would include discussion on the “theory of creative political expression to provide compelling examples of other, constructive and expressive options students have to respond to controversial speakers.”

This sounds good, but we will only find out if the administration means it when a conservative speaker decides to come to UC-Davis to speak. The article includes many comments from students who participated in the working group that opposed these recommendations and were hostile to allowing any dissenting voices on campus.

Ten planetary probes track a solar eruption through the solar system

9:02 am

The path of an October 2014 solar eruption was tracked by ten different spacecraft, including Curiosity on the surface of Mars, as its blast moved outward through the solar system.

The measurements give an indication of the speed and direction of travel of the CME [Coronal Mass Ejection], which spread out over an angle of at least 116 degrees to reach Venus Express and STEREO-A on the eastern flank, and the spacecraft at Mars and Comet 67P Churyumov–Gerasimenko on the western flank.

From an initial maximum of about 1000 kilometers per second (621 miles per second) estimated at the sun, a strong drop to 647 kilometers per second (402 miles per second) was measured by Mars Express three days later, falling further to 550 kilometers per second (342 miles per second) at Rosetta after five days. This was followed by a more gradual decrease to 450–500 kilometers per second (280-311 miles per second) at the distance of Saturn a month since the event.

The CME was first detected by solar observatories Proba-2, SOHO, Solar Dynamics Observatory, and STEREO-A.It was then tracked as it moved outward by Venus Express, Mars Express, MAVEN, Mars Odyssey, Curiosity, Rosetta, Cassini, and even New Horizons and Voyager 2.

On my last appearance on Coast to Coast, I was specifically asked if the probes to Venus, Mars, and other planets have the capability to track solar events. I knew that the Voyager spacecraft had equipment to do this, but was unsure about other planetary probes. This article answers that question.

More Russian launch delays

8:50 am

Three stories out of Russia today suggest that that country’s aerospace industry has not yet fixed all of its quality control problems.

The last two stories both refer to the launch of Germany’s Spektr-RG, which was originally supposed to launch in 2014. The most recent schedule said the astronomical observatory would be launched in September 2018. That they need an extra month in order to “integration and ground development of the Spektr-RG spacecraft” does not seem out of line. At the same time, that they do not provide any reasons for the delay raises questions.

Meanwhile, that the Proton rocket for the Amazonas-5 launch has not yet been shipped seems incredible. The September 9 launch date was announced on August 9. You would expect that by now Russian companies would know exactly how long it takes to get a rocket to the launchpad. This suggests another more fundamental problem with the rocket that they are not revealing.

I know I am being a bit harsh on the Russians here. A more positive spin (which also might be true) might be that they are finally getting a handle on their quality control issues, and the result is these few additional delays as they clean things up.

Radical left calls for more violence

11:31 pm

A wide range of leftist radical groups, most of which have been involved in the variety of violent attacks in the last year against conservatives, Republicans, and Trump supporters, are now calling for even more violence against anyone who opposes them.

Many of the same groups that have organized violent demonstrations in Berkeley, California and elsewhere are now calling for an aggressive response to the violence in Charlottesville. Far-left “anti-fascist” (or antifa) figures are advising agitators to do the job that police won’t: shutting down “fascists” and preventing them from organizing.

Radical left-wingers have for months justified violence as a way to fight back against “fascism” and “racism” — terms that they have applied not just to white nationalist fringe groups but to prominent figures on the right as well. “Charlottesville is just the beginning. If the alt-right can get away with murder there, none of us will be safe. We have to stand up to white supremacists, we have to shut down and chase out these bigots every time they try to organize, or else they will kill more people,” reads one poster created by anarchist group CrimethInc, a self-described “international network of aspiring revolutionaries.”

Read the whole article. If you have any doubts these are leftist groups, note that several condemn capitalism and democracy. Moreover, if you have read any history about the organizing tactics used by the Nazis in Germany, the Fascists in Italy, and the Communists in Russia and China, you will find the language and tactics here very familiar.

3D printing and how it will change what things look like

9:29 pm

Link here. The article not only outlines some of the newer developments in 3D printing, it gives a nice look at how that technology is literally going to change what the things it builds look like.

Simple shapes are popular in human designs because they’re easy. Easy to design, especially with CAD, and easy to manufacture in a world where manufacturing means taking a big block or sheet of something, and machining a shape out of it, or pouring metals into a mold.

But manufacturing is starting to undergo a revolutionary change as 3D printing moves toward commercially competitive speeds and costs. And where traditional manufacturing incentivizes the simplest shapes, additive manufacturing is at its fastest and cheapest when you use the least possible material for the job. That’s a really difficult way for a human to design – but fairly easy, as it turns out, for a computer. And super easy for a giant network of computers.

The result: a stronger object, less weight, and less cost.

North Korea appears to back down

6:27 pm

A news report today out of North Korea suggests that its leader, Kim Jong Un, has stepped back from a plan to test fire four missiles in the direction of Guam.

This could be related to China’s decision this week, under strong pressure from the Trump administration, to finally go along with UN sanctions and ban imports of iron, lead, and coal from North Korea.

A celebration of hate and ignorance

1:34 pm

The last few days have not been good ones for American free speech and freedom. Not only have we seen violence perpetrated to silence the free expression of dissent, we have seen an effort after the fact to use that violence as a club for destroying any opposition to the liberal and leftist dogma that dominates the American political and academic community.

The following links will provide a nice overview of how our cultural elites, especially on the left, have responded to this weekend’s terrible events in Charlottesville, Virginia, where one person was killed and almost twenty injured when a car rammed into a crowd of competing racist demonstrators.

That is how our elites responded, not with conciliatory remarks aimed at bringing people together, but with anger and hate, hate of Trump, hate of the Republican Party, hate of the NRA, hate of whites, hate for anyone that dared disagree with their leftist agenda. Then, when Trump issued a statement condemning all violence in the name of bigotry, the response was equally hateful:

The gentle storms of Saturn

10:03 am

Saturn's gentle storms

Cool image time! The Cassini image above, cropped and reduced slightly, shows a close-up view of Saturn’s cloud tops, taken during Cassini’s May 18, 2017 fly-by.

Clouds on Saturn take on the appearance of strokes from a cosmic brush thanks to the wavy way that fluids interact in Saturn’s atmosphere. Neighboring bands of clouds move at different speeds and directions depending on their latitudes. This generates turbulence where bands meet and leads to the wavy structure along the interfaces.

What I see is a much less turbulent storm pattern, when compared with Jupiter. This is not to say that the weather of Saturn is quiet or peaceful, for it certainly cannot be, considering the gas giant’s size and the depth of the atmosphere. Still, this image suggests that the turbulence is less violent here, possibly because Saturn is farther from the Sun and is hit with less solar energy, and because Saturn is smaller and thus produces less of its own internal energy.

Either way, it is beautiful and mysterious, in the way are all such images of alien places.
