  • Interesting fact: shrimp have their heart in their head
    • n head The upper part or division of the human body, consisting of the more or less rounded skull and its integuments and contents, the organs of sight, hearing, taste, etc., with the mouth and its parts, and joined to the trunk by the neck; in an extended sense, the corresponding part of any animal's body; the front, fore, or top part or oral end of an animal, in any way distinguished from the rest of the body, as by being borne upon a neck; the end opposite the tail. In all vertebrates except the lancelets, which have no skull or brain, the head is a prominent part. In arthropods, as insects and crustaceans, the head is an anterior part of the body in some way distinguished from the thorax, as by the coalescence of a number of the primitively distinct somites of the body into one segment, and the conversion of the appendages of these confluent somites into mouth-parts and organs of special sense; though the outward separation between head and thorax is often obscure or null. (See cephalothorax.) In the great group of worms, or anarthropodous anneloid animals, the head is simply the oral as opposed to the aboral end of the body. In molluscous animals a head is frequently recognizable by its mouth, tentacles, etc.; but in many there is no such distinction, these being called in consequence acephalous or headless. Still lower in the scale, the term head can be applied only, if at all, to the oral end of an animal. (See cranium and skull.) In certain Vermes the head is the whole mature individual excepting its generative buds, joints, or strobila: as, the head of a tapeworm.
    • n head Mental faculty regarded as seated in the head; intelligence; understanding; will or resolution; inclination; mind.

    • n head A part of a thing regarded as in some degree resembling the human head in position, form, or importance. The top, especially when distinguished in some way from the rest of the thing: as, the head of a pin, of a spear, of a nail, of a mast.
    • n head The top or upper part of a plant the leaves of which form a single more or less compact mass: as, a head of grain or of lettuce.
    • n head In botany, a more or less globular cluster of sessile or nearly sessile flowers centripetal in development, as in the plane-tree, button-bush, clover, etc. By the shortening of the rays the umbel becomes a head, as in Eryngium, Sanicula, etc. In the Compositæ the flowers are always collected into a head, but they are then situated on a conical, flat, or even concave receptacle. Gray calls such a head the anthodium, from the resemblance of the whole head to a single flower. In the Characeæ Sachs applies the term head (köpfchen) to a peculiar hyaline cell situated at the central end of each of the eight manubria. See head-cell, and cut under anthoclinium.
    • n head The main point or part; that which constitutes the most conspicuous or most important feature.

Fig. 12 shows that, consistently, the S−invariant estimate for linearization is also delayed in comparison with the head-on or near head-on cases.
Modeling gravitational radiation from coalescing binary black holes
We have applied our late-stage model to a sequence of initial data sets ranging from the head-on collision case to the ISCO data.
Modeling gravitational radiation from coalescing binary black holes
Having achieved the expected result in the head-on case we have slowly added orbital angular momentum.
