(y^2+2y+2 / y+1)+(y^2+8y+20 / y+4) = (y^2+4y+6 / y+2)+ (y^2+6y+12 / y+3)
~~~p.s. y^2 means : y x y ~~~~
y=?

IF students are not interested in math, should a teacher become so amaizingly intersting that students can't help themselves and learn the material?.
Does it require more thinking?.
Or, do some students just lack the intelligence to grasp such simple ideas.
Is math all that complex for high schooler now a days?. or have they become so brainwashed by TV, and Videogames, etc, that having to use the brain takes to much work?
Should we always blame math teachers for student laziness?

how can human beings make any sense at all of the world that they live in? Why does the universe have enough order for us to discern an underlying lawfulness, and yet enough chaos to permit such things as nature openness and human free will?

Pilots and observant people on the ground must have been seeing them forever. Did they not tell anyone or did scientists simply not believe them before they were officially 'discovered'?

Is there a reason why so many people hate math, and openly admit that they are the "worst possible person in math"

they seem to wear that fact as a badge of Honor..
who would ever admit to Not being able to Read?.. Math is an essential subject to maintain our modern way of life. without math, not much would be possible.

I'm having trouble understanding the terms crystallite, particle and grain. Here is what wikipedia says for grains: " Grain size refers to the physical dimensions of individual particles of rock or other solid". But when I look up particle, it does not list the geological sense of the word. For crystallite, wikipedia says this: "A crystallite is a domain of solid-state matter that has the same structure as a single crystal". Does this mean that a particle is a crystallite?
