The bulb is an archaic term for the medulla oblongata and in modern clinical usage the word bulbar (as in bulbar palsy) is retained for terms that relate to the medulla oblongata, particularly in reference to medical conditions.
Pi is transcendental. The endless number cannot be expressed by any algebraic equation. No pattern has been found in its digits, Yet it cannot be proven in a finite amount of time. That no pattern exists in an infinite number of digits. Pi goes beyond our reality.
Still, fractions such as 22/7 and other rational numbers are commonly used to approximate Ï. The digits appear to be randomly distributed; however, to date, no proof of this has been discovered. Also, Ï is a transcendental number â a number that is not the root of any non-zero polynomial having rational coefficients. This transcendence of Ï implies that it is impossible to solve the ancient challenge of squaring the circle with a compass and straightedge.
