To the finest tick mark on the ruler it is 3,142 millimeters. This is assuming no error in the construction of the circle or in the measuring of the string. To add another digit we would have to have a circle ten meters in diameter. This would give an approximation to the value of pi to be 3.1415. For another decimal place an impractically giant circle one hundred meters in diameter would have to be constructed. Even doing everything correct, the error would be plus-or-minus 0.0001, the ‘true value’ being between 3.1414 and 3.1416. Taunus Trumbo: At that rate to get five decimal-place accuracy, you would need a circle with a diameter of an Egyptian pyramid. Faustus Mortal: Yes, all sorts of errors can creep in then. Taunus Trumbo: Say you measure the value of pi many times, can’t you get a statistical mean and variance? So we can be accurate and precise? Faustus Mortal: String stretches and the surfaces vary. There are systemic as well as statistical errors. Taunus Trumbo: So. She was ready to have this baby now, Emily thought. Fortunately, being ina desk job, the pregnancy didn't get too much in the way of her work andthere had been a lot of scientific advances to make it more comfortablefor women and as such, most women worked right up until the day oflabour.Still, Emily thought as she rubbed her belly, she did miss going out inthe evenings with her colleagues and drinking themselves silly.Emily was brought back to the present when she heard a loud squeal comingfrom the bedroom. It sounded like Roger had found the walk-in closet. Shechuckled again and then, after a few minutes of struggling to get up,Emily went to find her husband.Resting against the door frame, Emily watched for a moment as her husbandtook in the massive closet that was now his. It wasn't enormous by anymeans, not like those ones that Emily had seen once on that show thatRoger loved to watch, Keeping Up With The Kardashian's but it wascertainly bigger than what they were used to."What do.
