Maths and physics visualizations

Lucas Vieira Barbosa: “Below is a mostly comprehensive gallery of all images — illustrations, diagrams and animations — that I have created for Wikipedia over the years, some of which have been selected as featured pictures, or even picture of the day. As you’ll probably notice, they’re mostly related to physics and mathematics, which are my main areas of interest.”

See for example the sine curve drawing process, cosine, sine and the unit circle, coupled oscillators. I often use these in my lessons, but have usually drawn them on the (chalk)board. My school is getting interactive whiteboards in more classrooms now, so these animations will come in very handy.

Matt Henderson publishes his animations on his Math and Science Blog matthen. Did you know that The focus of a rolling parabola traces out a catenary, the curve of a hanging chain held by its ends?

Happenings in Cologne on New Year’s Eve (2)

Deutsche Welle:

Update:
Cologne New Year’s Eve complaints rise sharply.

“Police say more than 500 complaints have now been filed in connection with the New Year’s Eve attacks, with about 40 percent involving sexual offenses. Germany’s justice minister said the violence appeared orchestrated.”

516 so far – yikes. I wonder how high this number will rise over the next few days.

German Justice Minister: Cologne attacks planned in advance.

“Minister of Justice Heiko Maas has said he believes the sexual assaults in Cologne were ‘coordinated and prepared’ ahead of time. He also accused xenophobic groups of using the crimes to stir up hatred.”

Cologne New Year assault reports more than double in number.

“Cologne police have said the number of women coming forward with complaints that they were assaulted on New Year’s Eve has risen to 379. A large minority of the reported crimes were said to be of a sexual nature.”

Happenings in Cologne on New Year’s Eve

I posted some links about this two days ago, but have decided to find some reports in English since there seem to be reports on this in other countries. Garret asks on his weblog: “Is this true, German friends?”

Update

MetaFilter: Cologne Police Chief Forced to Resign. “After more than 100 women and girls came forward with reports of sexual assault and robbery by gangs of men in the German city of Cologne on New Year’s Eve, Cologne’s police chief has been removed from his post.”

The discussion is ongoing, and there are more links in the front page post and the discussion.

Spiegel online international

Cologne Assaults: Police Report Outlines ‘Chaotic and Shameful’ New Year’s Eve.

“Law enforcement officials lost control of the situation in Cologne on New Year’s Eve, according to an internal report by Germany’s national police, the Bundespolizei, obtained by DER SPIEGEL. The author of the report, dated Jan. 4, is a senior official. He writes: “Women, accompanied or not, literally ran a ‘gauntlet’ through masses of heavily intoxicated men that words cannot describe.” The horde in front of and inside the train station was unmoved by the presence of police.”

Deutsche Welle

Protests: Police deploy in force at Cologne demos. “Police in the German city of Cologne have turned out in force at demonstrations by far-right groups and their opponents. The protests come in the wake of the attacks on women on New Year’s Eve.”

Refugees: Germany mulls deporting asylum seekers following Cologne attacks. “At a party meeting, Angela Merkel’s CDU party will address heightening security and lowering barriers to deporting migrants convicted of crimes. It comes on the back of the attacks on women in Cologne on New Year’s Eve.”

Germany: Reports: asylum seekers among Cologne attacks suspects. “Police identified some suspects who harassed women in Cologne on New Year’s Eve as asylum seekers, media reports say. City police reportedly did not want to publicize this because of its “politically awkward” nature.”

Germany: Merkel says Cologne NYE assaults will have far-reaching consequences. “German Chancellor Angela Merkel has said that the harassment of women at Cologne’s central train station on New Year’s Eve will have a far-reaching impact. She said such criminal acts were unacceptable in Germany.”

Other sources

Unfortunately Zeit online in English hasn’t published/translated any articles on this yet, but I’ll add more links from other reputable sources other than Spiegel online if and when I find them.

Some German news media seem to have exaggerated the events in their reports, for example Focus, who report:

“In der Silvesternacht versammelten sich auf dem Kölner Bahnhofsvorplatz laut Polizei etwa 1000 Männer, die Frauen umzingelt, bedrängt und ausgeraubt haben sollen. Polizeipräsident Wolfgang Albers sprach am Montag von Sexualdelikten “in sehr massiver Form” und einer Vergewaltigung.”

(My translation:) “During the night of New Year’s Eve around 1,000 men congregated at the square in front of the main train station in Cologne and surrounded, hassled and robbed women. Police superintendent Wolfgang Albers spoke of massive sex offences and one rape.”

They don’t distinguish between a gathering of 1,000 people and the men among them who committed the crimes, which were, according to other media, smaller groups of men.

Emotional Labor

A MetaTalk thread reminded me that I never posted a link to this excellent MetaFilter thread from July 2015 on emotional labor:

“Where’s My Cut?“ : On Unpaid Emotional Labor. (July 15, 2015)

“Housework is not work. Sex work is not work. Emotional work is not work. Why? Because they don’t take effort? No, because women are supposed to provide them uncompensated, out of the goodness of our hearts.

It took me the better part of two weeks to read that thread and some of the AskMetaFilter and Metatalk threads it spawned (selection, in chronological order), plus more time when later threads were posted:
