I think you are speaking of statistics generally. I am speaking of the AP Statistics course. It doesn't matter what statistics is. It only matters what college admissions officers will think when they read the list of AP courses on your transcripts. Or, rather, it matters what parents and students think colleges will think when colleges read their transcripts. For most parents and students, AP Stats is a math course and they've heard it's easier than AP Calculus. Choosing AP courses is a game, with the goal being to get into a good college. Learning something is a secondary objective.
Comment AP? (Score 5, Informative) 155
AP stands for Advanced Placement. The program intends to offer college-level courses to high school students. Each course culminates in a standard exam in the spring which is graded on a 1-5 scale. Some colleges award college credit to their students for AP courses they took in high school, depending on the score and the exam.

The role of AP Statistics is to offer an AP 'math' to students who don't stand a chance in AP Calculus, but who demand an AP math class on their transcript. Most do not consider AP Computer Science 'math' enough for it to play that role, hence the surge in AP Statistics. On top of that, AP Computer Science is perceived as being much harder than AP Statistics. For a Junior or Senior looking for a reliably easy AP, Computer Science is not the way to go.
Rube Goldberg and the Electrification of America 207
Hugh Pickens writes "Alexis Madrigal has an interesting essay in the Atlantic about the popular response of people in the 19th century to the development of the electric power industry in America. Before electricity, basically every factory had to run a bit like a Rube Goldberg machine, transmitting power from a water wheel or a steam engine to the machines of a manufactory but with the development of electric turbines and motors the public believed engineers were tapping mysterious, invisible forces with almost supernatural powers for mischief. 'Think about it,' writes Madrigal. 'You've got a wire and you've got a magnet. Switch on the current — which you can't see and have no intuitive way to know exists — and suddenly the wire begins to rotate around the magnet. You can reverse the process, too. Rotate the magnet around the wire and it generates a current that can be turned into light, heat, or power.' And that brings us back to Rube Goldberg, a cartoonist who was was shockingly popular in his heyday and whose popularity closely parallels the rise of electrification in America. 'I think Goldberg's drawings reminded his contemporaries of a time when they could understand the world's industrial processes just by looking. No matter how absurd his work was, anyone could trace the reactions involved,' writes Madrigal. 'People like to complain that they can't understand modern cars because of all the fancy parts and electronic doo-dads in them now, but we lost that ability for most things long ago.'"
Firefox To Replace Menus With Office Ribbon 1124
Barence writes "Mozilla has announced that its plans to bring Office 2007's Ribbon interface to Firefox, as it looks to tidy up its 'dated' browser. 'Starting with Vista, and continuing with Windows 7, the menu bar is going away,' notes Mozilla in its plans for revamping the Firefox user interface. '[It will] be replaced with things like the Windows Explorer contextual strip, or the Office Ribbon, [which is] now in Paint and WordPad, too.' The change will also bring Windows' Aero Glass effects to the browser." Update: 09/24 05:01 GMT by T : It's not quite so simple, says Alexander Limi, who works on the Firefox user experience. "We are not putting the Ribbon UI on Firefox. The article PCpro quotes talks about Windows applications in general, not Firefox." So while the currently proposed direction for Firefox 3.7 involves some substantial visual updates for Windows users (including a menu bar hidden by default, and integration of Aero-styled visual elements), it's not actually a ribbon interface. Limi notes, too, that Linux and Mac versions are unaffected by the change.

Optical Fiber With a Silicon Core 60
Roland Piquepaille writes "According to the Optical Society of America, U.S. researchers have been able to create a practical optical fiber with a silicon core. As they were able to use the same commercial methods that are used to develop all-glass fibers, this might pave the way for future silicon fibers as viable alternatives to glass fibers. The scientists note that this should help increase efficiency and decrease power consumption in computers and other systems that integrate photonic and electronic devices. Here is a good summary by the lead researcher: 'In the past, we've needed one structure to process light and another to carry it. With a silicon fiber, for the first time, we have the ability to greatly enhance the functionality in one fiber.'"
Oil-Immersion Cooled PC Goes To Retail 210
notthatwillsmith writes "Everyone's seen mods where someone super-cools a PC by submersing it in a non-conductive oil. It's a neat idea, but most components aren't designed to withstand a hot oil bath; after prolonged exposure materials break down and components begin to fail. Maximum PC has an exclusive hands-on, first look at the new Hardcore Computer Reactor, the first oil-cooled PC available for sale. Hardcore engineered the Reactor to withstand the oil, using space-age materials and proprietary oil. The Reactor's custom-manufactured motherboard, videocards, memory, and SSD drives are submersed in the oil, while the dry components sit outside the bulletproof tank. The motherboard lifts out of the oil bath on rails, giving you relatively easy access to components, and the overall design is simply jaw-dropping. Of course, we'd expect nothing less for a machine with a base price of $4000 that goes all the way up to $11k for a fully maxed out config."
Schneier on Security 204
brothke writes "There is a perception in both the
private and government sector, that security, both physical and digital, is
something you can buy. Witness the mammoth growth of airport security
products following 9/11, and the sheer number of vendors at security
conferences. With that, government officials and corporate executives
often think you can simply buy products and magically get instant security by
flipping on the switch. The reality is that security is not something
you can buy; it is something you must get." Keep reading for the rest of Ben's review.

narcberry writes "The BBC reports on a scientific community still holding to flat earth theories. From their article: 'Are there any genuine flat-earthers left? Surely in our era of space exploration — where satellites take photos of our blue and clearly globular planet from space, and robots send back info about soil and water from Mars — no one can seriously still believe that the Earth is flat? Wrong. Flat earth theory is still around. On the internet and in small meeting rooms in Britain and the US, flat earth believers get together to challenge the 'conspiracy' that the Earth is round.'"

As a further nit-pick, I'd note that icosahedrons are not made from pentagons. I think they mean dodecahedrons, the faces of which are pentagons:
An icosahedron is like a 3-D pentagon, and just as you cannot tile a floor with pentagons, you cannot fill 3-D space with icosahedrons, Royall explained. That is, you can't make a lattice out of pentagons.
Bizarre Properties of Glass Allow Creation of "Metallic Glass" 265
VindictivePantz writes to mention that scientists have discovered some bizarre properties of glass and are already applying that knowledge to create what is being called "metallic glass." "The breakthrough involved solving the decades-old problem of just what glass is. It has been known that that despite its solid appearance, glass and gels are actually in a 'jammed' state of matter — somewhere between liquid and solid — that moves very slowly. Like cars in a traffic jam, atoms in a glass are in something like suspended animation, unable to reach their destination because the route is blocked by their neighbors. So even though glass is a hard substance, it never quite becomes a proper solid, according to chemists and materials scientists."
UK Police Want DNA of 'Potential Offenders' 578
mrogers writes "British police want to collect DNA samples from children as young as five who 'exhibit behavior indicating they may become criminals in later life'. A spokesman for the Association of Chief Police Officers argued that since some schools already take pupils' fingerprints, the collection and permanent storage of DNA samples was the logical next step. And of course, if anyone argues that branding naughty five-year-olds as lifelong criminals will stigmatize them, the proposed solution will be to take samples from all children."
