4:38 PM | The New GCSE #7 Non-Calc Side by Side

Ok, these are the new specimen papers (the last ones have been thrown out essentially!) Each page is side by side for the 3 exam boards (there’s a fourth exam board, but they have 2 longer papers so the comparison is a bit more difficult, so i’ve omitted them). On hand is Michael Gove to … Continue reading →

Question 34, the first Part IV question of the New York State Geometry (Common Core) Regents exam for June 2015, read as follows: The water tower in the picture below is modeled by the two-dimensional figure beside it. The water tower is composed of a hemisphere, a cylinder, and a cone. Let C be the center of the hemisphere and let D be the center of the base of the cone. If AC = 8.5 feet, BF = 25 feet, and m∠EFD = 47°, determine and state, to the nearest cubic foot, the volume of the

4:00 PM | Ceaseless Tread of Pictures of PIctures

In his Sherlock Holmes story "The Man with the Twisted Lip" Arthur Conan Doyle had his character Dr. John Watson notice:Ordering my cab to wait, I passed down the steps, worn hollow in the center by the ceaseless tread of drunken feetAbove is a detail from the drawing "Twin Staircases in Vitorchianoby" by Rhode Island School of Design Professor Fred Lynch from his blog. It nicely illustrates Dr. Watson's observation. I found a comparable photograph of such stairs here. The tread of those […]

12:05 PM | Summer To-Do Diagram

(Click on the comic if you can't see the full image.) (C)Copyright 2015, C. Burke.It's oddly accurate while leaving out a whole lot of stuff. But definitely the proofreading! There are new curriculums to be learned, and I need to refresh in upper-level classes in case I'm called to teach those. And now is a good time to assess what worked and what didn't -- particularly, with the new material which I hadn't taught in the same manner before. So I'm not really off. ... except that I am.

8:06 PM | Thomas Sopwith’s Stratigraphic Models

Model-X – Thomas Sopwith [1841] First produced in 1841 Thomas Sopwith’s wooden models were some of the earliest three-dimensional representations of Earth’s geological strata. Layered, glued, hand carved and polished, his models demonstrate the abilities of a skilled woodworker and isometricist. Sopwith began his apprenticeship as a cabinet maker and so his interests in carpentry […]

Inizio, però, con un piccolo cappello, alla fine del quale saprete che c'è anche un piccolissimo pezzetto (il doppio diminutivo è perché i firmatari del papero su arXiv sono veramente tanti) d'Italia in questa interessante scoperta.Tutto nasce da un post, nel flusso twittero, di Annalisa Arci, in cui racconta, in maniera e con un […]

Come scrivono i Rudi Mathematici, "John Forbes Nash se n'è andato". C'è poco da dire in situazioni del genere, se non provare a scrivere, magari della sua matematica. Ho provato a farlo in modi piuttosto indiretti, lo faccio oggi in un modo un po' più diretto.Uno dei risultati più importanti di John Nash è la scoperta dell'esistenza degli equilibri che portano il suo nome all'interno dei giochi non collaborativi. La teoria di base su questo genere di giochi prende le mosse da due suoi […]

http://t.co/gCOlKccELA about #IngeLehmann #EarthCore #theCore #geophysics Inge Lehmann was a Danish seismologist and geophysicist. Using seismic data, she discovered the inner solid core of the Earth with some physical properties distinct from the outer liquid core: No rays emerged at epicentral distances between 112° and 154°. I then placed a smaller core inside the first core and let the velocity in it be larger so that a reflection would occur when the rays through the larger core met it.
