They’re about ideas and possibilities, not suffering. And millions are listening. Until a couple of years ago, Rob Fatzinger had a blog called Sardonic Catholic Dad, focusing on family, faith and frugality. Two of his hits: “College on the Cheap — How the Sardonic Family Does It” and “How to Retire Early With 13 Kids,” which he wrote as a guest post on the FIRE site Mad Fientist.
Frugalism is often about math, determinationand thinking a bit differently. A few key principles: How much you save, as a percentage of your paycheck, will foretell when you’ll be able to build your own business or retire. Small financial changes can make a big impact. And it’s not really about your income; it’s about your savings, says Pete Adeney, a lapsed engineer from outside Boulder, Colo., who created the popular Mr. Money Mustache blog.
Rio 2016: Photos From the First Weekend (jdargis)
Hundreds of photographers have gathered in Rio to follow the action in the Olympic arenas, swimming pools, racetracks, and more. Over the next two weeks I’ll be featuring some amazing images from recent Olympic events. Today’s entry encompasses fencing, basketball, handball, swimming, diving, eventing, table tennis, archery, and much more.
The sequences below capture five American gymnasts — Simone Biles, Gabby Douglas, Laurie Hernandez, Madison Kocian and Aly Raisman — during their gold medal-winning performance alongside images of their parents, taken at about the same time.
Scheier is a mother of three—her middle child, Oliver, has muscular dystrophy. When he turned 8, she said he started to become fashion-conscious. He wanted to wear, say, jeans, but it was hard for him to manage the buttons and zippers. “He viewed himself like other kids,” she says, “so why couldn’t he wear what they were wearing?”
Karma is among the first to use solar panels to charge a production car’s high-voltage battery that powers the motor. The predecessor company’s original car, called the Fisker Karma, used a solar panel to charge the 12-volt battery that powers lights and other accessories and Toyota Motor Corp. has used solar power in the Prius to run the ventilation system. Toyota’s new Prius Prime plug-in, going on sale this year, will have an optional solar panel to charge the battery for buyers in Europe.
Mary Gustanski, vice president of engineering and program management at Delphi, an auto supplier that is going to produce 48-volt systems for car companies, believes these hybrids can improve the fuel economy of normal gasoline-powered cars by 15 percent or more with little additional cost. “Is it leaps and bounds?” she said. “No, but does it move us further along? Definitely.”
Now a team from the HZB Institute for Soft Matter and Functional Materials headed by Prof. Matthias Ballauff has directly observed for the first time a lithium-silicon half-cell during its charging and discharge cycles. “We were able to precisely track where the lithium ions adsorb in the silicon electrode using neutron reflectometry methods, and also how fast they were moving”, comments Dr. Beatrix-Kamelia Seidlhofer, who carried out the experiments using the neutron source located at the Institute Laue-Langevin.
Bill Cooke, the head of NASA’s Meteoroid Environment Office, tells Nell that a typical Perseid meteor shower “has 80 to 100 meteor showers per hour.” But in the upcoming shower, “we’re going to have anywhere from 160 to 200 meteors per hour. So the rates are going to double this year.”
