Math education needs a reboot. Kids today are growing up into a world awash in data, and they need new skills to make sense of it all. The list of high school math courses in the U.S. hasn’t changed for decades. My daughters are taking the same courses I took long ago: algebra, geometry, trigonometry, and calculus. These are all fine subjects, but they don’t serve the needs of the 21st century. What math courses do young people really need? Two subjects are head-smackingly obvious: computer science and statistics. Most high schools don’t offer either one. In the few schools that do, they are usually electives that only a few students take. And besides, the math curriculum is already so full that some educators have argued for scaling back. Some have even argued for getting rid of algebra, as Andrew Hacker argued in the NY Times not long ago. So here’s a simple fix: get rid of high school calculus to make way for computer programming and statistics. Computers are an absolute mystery to most non-geeks, but it doesn’t have to be that way. A basic computer programming class requires little more than a familiarity with algebra. With computers controlling so much of their lives, from their phones to their cars to the online existence, we ought to teach our kids what’s going on under the hood. And programming will teach them a form of logical reasoning that is missing from the standard math curriculum. With data science emerging as one of the hottest new scientific areas, a basic understanding of statistics will provide the foundation for a wide range of 21st century career paths. Not to mention that a grasp of statistics is essential for navigating the often-dubious claims of health benefits offered by various “alternative” medicine providers. (While we’re at it, we should require more statistics in the pre-med curriculum. Doctors are faced with new medical science every day, and statistical evidence is the most common form of proof that a new treatment is effective. With so much bad science out there (just browse through my archive for many examples), doctors need better statistical knowledge to separate the wheat from the chaff.) Convincing schools to give up calculus won’t be easy. I imagine that most math educators will scream in protest at the mere suggestion, in fact. In their never-ending competition to look good on a blizzard of standardized tests, schools push students to accelerate in math starting in elementary school, and they offer calculus as early as the tenth grade. This doesn’t serve students well: the vast majority will never use calculus again. And those who do need it – future engineers, physicists, and the like – can take it in college. Colleges need to adjust their standards too. They can start by announcing that high school programming and statistics courses will be just as important as calculus in admissions decisions. If just a few top universities would take the lead, our high schools would sit up and take notice. We can leave calculus for college. Colleges teach calculus well, and 18-year-old freshmen are ready for it. Every major university in the country has multiple freshman calculus courses, and they usually have separate courses designed for science-bound and humanities students. Many students who take high school calculus have to re-take it in college anyway, because the high school courses don’t cover quite the same material. Let’s get rid of high school calculus and start teaching young students the math skills they really need. |
A barbaric, bear trap-like device called a biter was used by ISIS to torture a breastfeeding mother in Syria, a report said Tuesday. The 24-year-old new mom, referred to as Batol to conceal her identity, was walking through the city of Raqqa when she was snatched up by the Islamic States all-female police squad the notorious al-Khansa brigade, the Daily Mail reports. I was in the market buying a few items when Khansa battalion came and arrested me on the grounds that the niqab [Islamic face covering] which I was wearing does not meet Sharia requirement because it was transparent, she said. [T]hey took me to the Hesba headquarters in the city, and escorted me to the torture chamber, then they asked me to choose between a whip or a biter. I did not know what a biter was and I thought it is a reduced sentence, she added. I was afraid of whipping, so I choose the biter.' They brought a sharp object that has a lot of teeth and held me, placing it on my chest and pressing it strongly, she said. I screamed from pain and I was badly injured. They later took me to the hospital. Fighters from the Islamic State group parade in Raqqa. Photo: AP The horrifying details were obtained by anti-ISIS media group Raqqa Is Being Slaughtered Silently, according to the Daily Mail. I felt then that my femininity has been destroyed completely, Batol continued. We no longer afford to live this way, I was not the only one that was tortured with this instrument, there were a lot of women in the headquarters and their situation was tragic. The al-Khansa brigade has become infamous for its savagery in recent months after countless British women who joined the ISIS insurgency began boasting about their membership on social media. The group bragged about handing out merciless beatings, severe lashings, managing sex slaves and ordering executions, according to the Daily Mail. Even though Batols claims could not be verified, the account matches stories that other people have told about the al-Khansa extremists behavior. |
Wile E. Coyote just got a shipment of an infinite number of bombs, and he's ready to blow up the Road Runner once and for all. However, the rules of the game this time around are a bit different from the usual. You see, this world is one dimensional, so the Road Runner only runs in a straight line. Also, the world is discrete, and everything has integer values. The Road Runner starts at an integer location and moves at a constant integer velocity. Since time is also discrete, the Road Runner warps from his current location to his next location every second, instead of running continuously on the line. The problem for Wile E. Coyote is that he doesn't know the Road Runner's velocity or starting location, but he can fire one bomb at any location, every second. Devise a strategy for Wile E. Coyote that, given an infinite amount of time, assures that he will finally be able to blow up the Road Runner. |

Sometimes a fare that travels through a hub city to another location can be cheaper than a ticket to the hub city alone. “In its simplest form, a passenger purchases a ticket from city A to city B to city C but does not travel beyond city B,” according to the companies’ complaint. “‘Hidden City’ ticketing is strictly prohibited by most commercial airlines because of logistical and public-safety concerns.” |
The Islamic State group has executed nearly 2,000 people since it started its campaign in June to take over large swaths of land in Iraq and Syria. About half of those who have been executed were part of a prominent Sunni tribe that rose up against ISIS in the eastern province of Deir el-Zour, the Syrian Observatory for Human Rights, a monitoring group in Britain, said Sunday. The Syrian Observatory for Human Rights has documented the execution by the Islamic State of 1,878 people in Syria between June 28 when it announced its caliphate and Dec. 27, the monitoring group said in a statement. About 930 of those executed were from the Shaitat tribe. Of those killed, 1,175 were civilians, including four children and eight women. |
JAKARTA, IndonesiaOfficials said they would expand yet again the search area for a missing AirAsia jetliner, after a second day of combing the waters with an arsenal of planes and ships failed to yield signs of the airplane carrying 162 people. Officials said 30 vessels and 15 planes were deployed Monday to scour waters around Bangka Island, south of Singapore and north of the island of Borneo. The area already had been widened from the initial search area on Sunday. Indonesia AirAsia Flight 8501 vanished in a thicket of storm clouds en route to Singapore from the Indonesian city of Surabaya on Sunday morning. It lost contact with air-traffic control less than an hour after takeoff after requesting permission to climb to a higher altitude to avoid bad weather, officials said. The head of the National Search and Rescue Agency, Bambang Soelistyo, said search and rescue teams Tuesday will also start searching the water south of Bangka Island, and widen the area of search in the western part of Borneo. No signals have yet to be detected from the planes emergency locator transmitters. Mr. Soelistyo, who earlier Monday said they suspect the plane was at the bottom of the sea, said Indonesia is requesting a submersible from France, the United Kingdom or the U.S. to help find the missing plane. We have coordinated with the Ministry of Foreign Affairs to borrow a submersible, he said. |
The search is on for AirAsia Flight 8501, which lost contact with air traffic control in Indonesia, the airline said Sunday. Flight QZ 8501 from the Indonesian city of Surabaya to Singapore lost contact with air traffic control at 7:24 a.m. Sunday (5:24 p.m. Saturday ET), AirAsia said. "At the present time we unfortunately have no further information regarding the status of the passengers and crew members on board, but we will keep all parties informed as more information becomes available," AirAsia said in a statement. The plane had 155 passengers and crew on board, the news agency Reuters reported, citing Indonesian transport officials. |

It's way past the optimal window for doing this, but if I can get enough responses, we could really home in on what the mean is for many of these questions and instead of 1.375-1.875 for a given question, your score range may be narrowed down to 1.375-1.5, and in some cases, your exact score may be apparent. If you wish to participate, fill out a copy of the attached excel workbook and email it to exam5_ca@outlook.com. If you do not have excel, you scan your Candidate's Analysis page and email it. Everyone who sends in their scores will get a response from me each week if new papers come in. Only participants will benefit in order to encourage more people to share their results. Might be mildly useful in prepping for the fall to know that you got 2 points on a question rather than 1.5-2 points. Also, tell your friends/coworkers who are not on the outpost. |

Continuous-time models will also be presented for comparison. Topics will include characterization of optimality, stability, sensitivity, and robustness, approximation, statistical, and convergence properties, asymptotic and extremal distributions, and computational complexity. Students will develop skills to represent complex decision problems in a tractable form, to solve large-scale problems, and to describe resulting solution properties. Students will be prepared to read, understand, and interpret recent literature in the field. |
The idea of ridding all of New Zealand of its mammalian predators was proposed by Paul Callaghan, a world-renowned physicist, in a speech delivered in Wellington, in February, 2012. In scientific circles, Callaghan was celebrated for his work on nuclear magnetic resonance; to Kiwis he was probably best known for having recently been named New Zealander of the Year. At the time he gave the speech, Callaghan was dying of cancer, and everyone who heard it realized that it was one of the last he would deliver. (He died the following month.) “Let’s get rid of the lot,” Callaghan said. “Let’s get rid of all the predators—all the damned mustelids, all the rats, all the possums—from the mainland.” |
