From SharpBrains.
They have put together a selection of the 50 Brain Teasers that people have enjoyed the most in their blog and speaking engagements.
They classify them into attention, memory, pattern recognition and planning, visual workouts and illusions, logic, math puzzles and some fun experiments.
Have a good workout!

It’s an odd combination of Navier-Stokes equations and NASCAR driving. Computer scientists at the University of Washington have developed software that is incorporated in new technology allowing television audiences to instantaneously see how air flows around speeding cars.
The algorithm Model Reduction for Real-time Fluids, first presented at a SIGGRAPH computer graphics conference last August, [...]

Some have called Euler the “Mozart of Mathematics,” not only because of his genius but because of his prodigious output.
Euler contributed to essentially every field of mathematics — calculus, geometry, number theory and the vast realm of applied mathematics. “He was a universalist when that was still possible,” said Dunham, who has just edited [...]
From Antonio Math blog.
I don’t remember having to learn the vertex, focus, and directrix of the parabolas or the center, vertices, foci, and eccentricity of the hyperbola. Other than that, it is ok.
Just a note to Factor the polynomial x3 - 27 without knowing the formula.
First, when x = 3, x3 - 27 = 0 [...]
