What Has Many Needles but Doesn't Sew?

"What has many needles but doesn't sew?" This is a riddle that has been around for centuries, and there are many possible answers. The most common answer is a porcupine, but other answers include a cactus, a hedgehog, or a pincushion.

Porcupines are one of the most popular answers to this riddle because they are covered in sharp spines or quills. These quills are actually modified hairs that are very sharp and can cause serious injury if they puncture the skin. Porcupines use their quills for self-defense, and they can detach from the animal's body if they become embedded in an attacker.

Cacti are another common answer to this riddle. Like porcupines, cacti are covered in sharp spines. These spines are used to deter predators and to protect the cactus from being eaten. Cacti have a slow-growing stem, and they can live for hundreds of years in the desert.

Hedgehogs are another possible answer to this riddle. Hedgehogs are small, spiny mammals that are found in Europe, Asia, and Africa. Hedgehogs have a coat of sharp spines that protect them from predators. These spines are made of keratin, and they are sharp enough to penetrate the skin.

Pincushions are the final possible answer to this riddle. Pincushions are small, round, and prickly. They are used to store pins and needles. Pincushions are usually made of fabric, and they are filled with a variety of materials, such as sawdust, sand, or rice.

There are many ways to think about the dimensions of an object. One way to think about dimension is as the physical specification of an object in terms of length, width, and height. In this way, a book might be said to have the dimensions 11 inches by 8.5 inches by 0.75 inches. Another way to think about dimension is as a measure of the size or magnitude of an object. In this way, we might say that the Sun has a diameter of about 864,000 miles, or that Mount Everest is approximately 29,029 feet tall.

Still another way to think about dimension is in terms of the number of spatial dimensions an object occupies. Most everyday objects, like books, people, and cars, occupy three dimensions (length, width, and height), which we can think of as being in x-, y-, and z-directions. But there are also objects that occupy two dimensions, like paintings or photographs, which we can think of as being in the x-y plane. And there are even objects that occupy just one dimension, like points or lines.

So when we ask the question "What are the dimensions of this object?," we need to first determine what we mean by "dimension." If we are asking about the physical specification of an object in terms of length, width, and height, then we can simply measure the object and give its dimensions. If we are asking about the size or magnitude of an object, then we need to find some way to quantify that size or magnitude. And if we are asking about the number of spatial dimensions an object occupies, then we need to determine how many directions we can move in with respect to that object.
