Computational Thinking: AP Computer Science Vs AP Statistics?

pjhenley Re:AP Stats is the easy AP math (155 comments)

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.

Computational Thinking: AP Computer Science Vs AP Statistics?

pjhenley AP? (155 comments)

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.

Computational Thinking: AP Computer Science Vs AP Statistics?

pjhenley AP Stats is the easy AP math (155 comments)

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.

Bizarre Properties of Glass Allow Creation of "Metallic Glass"

pjhenley Re:Perpetuating old myths (265 comments)

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.

NYTimes Magazine interviews the Trolls

pjhenley pjhenley writes  |  more than 6 years ago

pjhenley (98045) writes "The New York Times Magazine today offers a story in which reporter Mattathias Schwartz interviews the trolls behind some high-profile hoaxes. The article digs into what motivates trolls, which they seem to have given some thought to:

Another troll explained the lulz as a quasi-thermodynamic exchange between the sensitive and the cruel: "You look for someone who is full of it, a real blowhard. Then you exploit their insecurities to get an insane amount of drama, laughs and lulz. Rules would be simple: 1. Do whatever it takes to get lulz. 2. Make sure the lulz is widely distributed. This will allow for more lulz to be made. 3. The game is never over until all the lulz have been had."

pjhenley (98045) writes "Have you noticed that DVDs always have read errors around the climax of a film? (no, I mean for real) The cause has to be that the inside of the disc is read between 1:30 and 2:00 of the film and that's the fastest spinning part of the disc given constant angular velocity. Can you think of a more flawed design? Do you know who to complain to? (and why can't Google verify my claim?)"
