I know it seems ignorant but I am a well educated person and its something that intrigues me. If they are born without the ability to communicate how do we tell them what they are, indeed who they are? Surely as they are in a constant 'in your head' state, then do you think they are always thinking - what is going on? Why is someone putting stuff in my mouth? And do they think that we all must be like this?!! It really confuses me!

Is there a mathematical formula, algorithm, or other theorem that no degree of computational power could process any faster.
In other words, is there a mathematical problem that, while solvable, can not be solved any faster by a faster computer.

Question:The ratio of an angle to its supplement is 3:7. Find the ratio of the angle to its compliment.

How do I solve this type of problem? I know it has something to do with proportions, but I'm not sure how...

A skater is initially spinning at a rate of 11.1 rad/s with a rotational inertia of 2.54 kg·m2 when her arms are extended. What is her angular velocity after she pulls her arms in and reduces her rotational inertia to 1.65 kg·m2?

What is 25% of 180?
answer: 45

How would you write the equation?
n = 25 * 180
n = .25 * 180
n = 1/25(180)

and the owner is repairing a flat tire. A friend spins the other wheel (radius r=0.4m) and observes drops of water fly off tangentially. They measure the height reached by the drops moving vertically. A drop that breaks loose from the tire on one turn rises h1 = 78 cm above the tangent point. A drop that breaks loose on the next turn rises h2 = 75 cm above the tangent point. The height to which the drops rise decreases because the angular speed of the wheel decreases. Acceleration of gravity is 9.8 m/s^2 and angular decelaration is constant. Find the magnitude of the angular deceleration fo the wheel in units of rad/s^2.
