” they need to generate their own equation, then solve it. (Generation is also mentioned byMake It Stickas a way to increase stickiness.) When they get it right, move it down a box. When box 2 is full, practice those the next session, and so on....
We manipulated the perception of the benefactors' intentions by providing additional information about whether the benefactor knew the participant could (i.e., Repayment possible condition), or could not (i.e., Repayment impossible condition) reciprocate after receiving help. In fact, participants ...
That’s the beauty of math: There’s always an answer for everything, even if takes years, decades, or even centuries to find it. So here are nine more brutally difficult math problems that once seemed impossible, until mathematicians found a breakthrough. PLUS: This Math Trivia Question Is...
It’s almost impossible to find the limit a functions without using a graphing calculator, because limits aren’t always apparent until you get very, very close to the x-value. The TI-89 is one of the best calculators for calculus; if you have another brand (like an HP), the steps ...
is the role that pure math played in all these discoveries. He was bewildered by the amazing fact that concepts once explored by mathematicians with absolutely no application in mind have turned out decades later to be unexpected solutions to real-world problems. A long time ago when Pythagoras...

As first demonstrated by the characterization of the quantum Hall effect by the Chern number, topology provides a guiding principle to realize the robust properties of condensed-matter systems immune to the existence of disorder. The bulk–boundary corre
隐函数定理使我们能够(部分)将非线性方程组的不可能问题(impossible questions)简化为线性方程组的简单问题(straightforward questions about systems of linear equations.)。这太棒了! 这个定理很棒,但它并不神奇(not miraculous),所以它有一些局限性(some limitations)。其中包括 ...
