What do you call an imperfect circle

Put together, the words mean circular form. Another interpretation suggests that Enso can mean a Circle of Togetherness. The more traditional interpretation of the symbol is that of the circle of life, as a symbol of the start and end of all things. The telecommunications company, Lucent Technologies, uses a red symbol that looks strikingly like the Enso to reflect the idea of creativity.

AMD used the Enso as a way to market its Zen microchips, as the company claimed that the Enso reflected the creative human spirit. The Enso is often featured in minimalist jewelry, especially in rings, pendants and earrings. The symbol makes for an ideal gift to someone due to its many symbolic interpretations and universal applicability.

Some excellent occasions for gifting the Enso include:. The Enso symbol is also popular as a tattoo design and is also often featured on clothing and other retail items. Drawing an Enso is a symbolic gesture that provides a sense of calm and relaxation. While it looks easy, it can also be quite complex to paint. The two things to remember when brushing an Enso are:. It would appear that the results you're quoting for the circularity only hold under some approximations. One of the definitions of circularity is via fitting the data to a circle, by optimizing the following error function, which measures deviations from a perfect circle, with respect to it's parameters:.

This problem however is non-linear, and thus analytical expressions for the estimators cannot be derived. This is easy enough to solve explicitly but, if we would like a really simple formula, then we can also assume that the angles at which the measurements are taken are equally spaced which is a reasonable assumption to make for engineering purposes.

As one moves the true center away from 0,0 more and more, one should find that the textbook estimators provided above are less and less accurate. We shouldn't be mixing the two, and each time we estimate roundness we should be referring to the method used to estimate it. Not all methods give the same answers, but they do give similar answers for many regular examples.

Each point would need to be precise from the particle level to the molecular level, whether the circle is stationary or in motion, which makes determining perfection a tricky feat. Much like Schrodinger's cat's suspended existence, the answer is not clear cut — there are all kinds of possibilities. In this vein, maybe a circle in nature is perfect, maybe it isn't, but our ways of knowing are limited by the constraints of our physical senses.

What we do know is that perfect circles abound in mathematics where lines and points are safe from the finite restrictions and forces of the material world. Man-made circles — that may or may not be perfect — abound around CMU's Pittsburgh campus.
