Deutsche Welle: Brille nötig: Kurzsichtig durchs Smartphone. “In 30 Jahren wird jeder zweite Mensch kurzsichtig sein. Schuld ist auch die übermäßige Nutzung von elektronischen Medien, vor allem bei Kindern. Dabei läßt sich Kurzsichtigkeit leicht vermeiden.”
“Der ständige Blick auf den Bildschirm kann vor allem Kinderaugen reizen, ermüden und austrocknen. Eine übermäßige Nutzung von elektronischen Medien führt nach Ansicht der Wissenschaftler aber nicht nur zu mehr Kurzsichtigkeit, es leidet auch das räumliche Vorstellungsvermögen. Verschwommenes Sehen oder Schielen können die Folge sein. “
NPR: Trump Administration Eases Regulation Of Methane Leaks On Public Lands.
“The Trump administration is rolling back another Obama-era energy regulation, this time one that aimed to curb methane leaks from oil and gas operations on tribal and public lands.
Methane is a powerful greenhouse gas, even more potent than carbon dioxide in the short term, that contributes to climate change. The Obama administration said that large amounts of methane are lost into the atmosphere through leaks, as well as intentional venting and flaring at energy production sites. It moved to limit that by requiring oil and gas companies to capture leaking and vented methane at existing sites, to gradually update their technology and to make plans for monitoring escaping gas.
The Government Accountability Office says as much as $23 million of potential royalty revenue from those gases is lost annually.
But in a statement, the Department of the Interior said that rule was “unnecessarily burdensome on the private sector.“”
This is kind of an understatement. Each ton of methane has about the same effect as 21 to 25 tons of carbon dioxide, so it’s much worse. How about methane being “burdensome on the world’s climate”?
The Washington Post: I was sexually assaulted. Here’s why I don’t remember many of the details. By Patti Davis, author and daughter of President Ronald Reagan.
“It’s important to understand how memory works in a traumatic event. Ford has been criticized for the things she doesn’t remember, like the address where she says the assault happened, or the time of year, or whose house it was. But her memory of the attack itself is vivid and detailed. His hand over her mouth, another young man piling on, her fear that maybe she’d die there, unable to breathe. That’s what happens: Your memory snaps photos of the details that will haunt you forever, that will change your life and live under your skin. It blacks out other parts of the story that really don’t matter much.”

The New York Times: On Hurricane Maria Anniversary, Puerto Rico Is Still in Ruins. “By Frances Robles and Jugal K. Patel. September 20, 2018.
“A year ago, on Sept. 20, the deadliest storm to hit Puerto Rico in over 100 years slammed into the island’s southeast coast, just 14 miles south of where Ms. Cruz lives in Punta Santiago. The tourist and fishing town of 5,000 people bore a terrible share of Maria’s initial fury.
Almost 650 houses flooded with water from the sea; others were inundated by an overflowing lake, a river, and two ponds — and also raw sewage. Many homes lost walls and roofs in winds that reached 155 miles per hour when the storm made landfall.
Times journalists visited 163 homes in two neighborhoods in Punta Santiago to cover what progress had been made in the last 12 months.”

Tables Generator lets you create tables for LaTeX or HTML documents
“Entering tables in LaTeX documents can be burdensome because of the necessary formatting directives. For this purpose we created this online generator which (hopefully) will allow you to generate LaTeX code you can just copy & paste into your document’s source. Our editor is close to WYSIWYG (What You See Is What You Got) principle, i.e. the table displayed in the editor should resemble the final table.
Creating tables in HTML seems to be somewhat easier than in LaTeX, the syntax is simpler but more verbose. There are countless tools available which allow you to create tables in HTML format, nevertheless if you just need a quick and simple tool you may use the generator on our site. It supports features like cells merging, text align and some simple styling.”
I found this site the other day while trying to typset a table for a math test in LaTeX in which I needed merged cells across several rows and columns. Worked like a charm!
