Comment explique-t-on ces phénomènes de stabilité ou d'instabilité ? Mathématiquement parlant, les équations qui régissent l'évolution d'un fluide sont loin d'avoir livré tous leurs mystères...

★On each face of the cube in the diagram, adjacent midpoints of the edges are connected with line segments. The eight corners of the cube are cut off along the lines, and a solid figure remains, as shown.⒜ What is the name of the shape cut off from each corner of the cube? ⒝ In the solid figure that remains, how many faces, how many edges, and how many vertices does it have?
대전역에서 광명역, 광명역에서 인천공항까지 허겁지겁 도착. 피치항공 마지막 밤 비행기를 타고 오사카 간사이공항에 무사히 도착했습니다! 날씨가 좋지 않아 예정시간보다 좀 늦게 도착했습니다. 간사이 공항 관제탑에서 나쁜 기상 탓인지, 좀처럼 착륙허가를 내 주지 않더군요. 미리 도착해 있는 다른 피치항공 비행기들. … Continue reading →Related Posts ?[출장 01]
A critique of Common Core math standards: Valerie Strauss:
I recently posted a piece on the future of high school math education and the Common Core State Standards on math, which was the work of a coalition of mathematicians, statisticians, teachers and curriculum developers, that elicited a lot of interest. The following response takes a critical look at that piece and the Common Core math standards. It was written by Michael Goldenberg, who holds a master’s degree in mathematics education
Re: Phyllis Chiasson I’m still a bit fuzzy on how Aristotle’s account relates to Peirce’s usage, though I’m pretty sure Peirce must have taken Aristotle’s usage into account, but it does seem that Aristotle drew some sort of distinction here, … Continue reading →
Today is 11/12/13, the last date this century with three consecutive numbers: Alex Bellos:
Humans like seeing patterns in randomness since it gives the illusion of control. A date that is a numerical pattern gives us a pleasing sense of control over the passing of time.
