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.
Part of the Mathematics glossary: A transcendental number is a real number that is not the solution of any single-variable polynomial equation whose coefficients are all integers. All transcendental numbers are irrational numbers. But the converse is not true; there are some irrational numbers that are not transcendental. Examples of transcendental numbers include pi, the ratio of a circle's circumference to its diameter in a plane, and e, the base of the natural logarithm. The case of pi has historical significance.
