Hundreds sign petition to bring back teacher who used the N-word in class submitted by Voat_a_Goat_Mamma to news

"She is a history teacher, she cannot be censored for teaching terms and beliefs that people had throughout history," the petition read.

A very simple point; hopefully, it will win out.

This could be just bait really.

He's laying it thick on the PR.

Linked Guardian article:


The judge who originally jailed him, Sally Cahill QC, specifically said that the fact the victims were Asian had been factored in as an “aggravating feature” when passing sentence.

She explained at the time that the victims and their families had suffered particular shame in their communities because of what they had endured. There were also cultural concerns that the girls’ future prospects of being regarded as a good candidate for arranged marriages could be damaged.

Since cultures play a role, what happens to the child after being assaulted might be different: this does not mean that punishments should be changed due to the ethnicity of the child.

Mark Fenhalls QC, chair of the Criminal Bar Association, said that the Sentencing Council’s guidelines require judges to consider, as a priority, the seriousness of the psychological and physical harm suffered by the victim.

He said: “The justice system does not look to favour one section of the community over another. The judgment reflects the duty of judges to take proper account of the extent of the harm suffered by individual complainants when deciding on the appropriate length of sentence in each case.”

At least the appeal to blind justice is still there.

Commenting on the case, an NSPCC spokesman said that any sentence should not depend on cultural background. “British justice should operate on a level playing field and children need to be protected irrespective of cultural differences,” he said.

Although there are extenuating circumstances, justice should be applied equally to all.

Nintendo has always had this weird control freak mentality that's always been to their detriment.

Being protective of their IP did help video games in general after the 1980s crash. It helped set a standard that was good for the industry overall.

Water Footprint of Hydraulic Fracturing submitted by redorangev to Chemistry

We evaluated the overall water footprint of hydraulic fracturing of unconventional shale gas and oil throughout the United States based on integrated data from multiple database sources. We show that between 2005 and 2014, unconventional shale gas and oil extraction used 708 billion liters and 232 billion liters of water, respectively. From 2012 to 2014, the annual water use rates were 116 billion liters per year for shale gas and 66 billion liters per year for unconventional oil. Integrated data from 6 to 10 years of operation yielded 803 billion liters of combined flowback and produced water from unconventional shale gas and oil formations. While the hydraulic fracturing revolution has increased water use and wastewater production in the United States, its water use and produced water intensity is lower than other energy extraction methods and represents only a fraction of total industrial water use nationwide.

Mathematics of the Faraday Cage submitted by redorangev to Mathematics

The amplitude of the gradient of a potential inside a wire cage is investigated, with particular attention to the 2D configuration of a ring of $n$ disks of radius $r$ held at equal potential. The Faraday shielding effect depends upon the wires having finite radius and is weaker than one might expect, scaling as $|\log r|/n$ in an appropriate regime of small $r$ and large $n$. Both numerical results and a mathematical theorem are provided. By the method of multiple scales, a continuum approximation is then derived in the form of a homogenized boundary condition for the Laplace equation along a curve. The homogenized equation reveals that in a Faraday cage, charge moves so as to somewhat cancel an external field, but not enough for the cancellation to be fully effective. Physically, the effect is one of electrostatic induction in a surface of limited capacitance. An alternative discrete model of the effect is also derived based on a principle of energy minimization. Extensions to electromagnetic waves and 3D geometries are mentioned.

Discussion (excerpt):

This article has investigated an electrostatic problem. Our analysis shows that the shielding improves only linearly as the spacing between wires of a cage shrinks, and this is probably why your cell phone often works inside an elevator. The shielding also depends on having wires of finite thickness, and this is probably why it is hard to see into your microwave oven. (If thin wires provided good enough shielding, the designers of microwave oven doors would use them.) Bjorn Engquist has pointed out to us an amusing illustration of the challenges of Faraday shielding that combines both of these devices. Put your cell phone inside your microwave oven, close the door, and give it a call. The phone will ring merrily!
