hydrogen bomb. hydrogen bomb or H-bomb, weapon deriving a large portion of its energy from the nuclear fusion of hydrogen isotopes. In an atomic bomb, uranium or plutonium is split into lighter elements that together weigh less than the original atoms, the remainder of the mass appearing as energy.nlike this fission bomb, the hydrogen bomb functions by the fusion, or joining together, of lighter elements into heavier elements. The end product again weighs less than its components, the difference once more appearing as energy.

The term-itis in medical terminology means inflamed so Plantar Fasciitis means Inflamed Plantar Fascia. Inflammation is part of it but what is really going on could better be described as a small tear or micro-tear at one end of the Plantar Fascia, usually the end attached to the heel. Plantar fasciitis can be found in both rigid and hyper mobile feet. 2  With excessive pronation the plantar fascia is overstretched as the medial longitudinal arch collapses. 3  In a rigid foot, the calf muscles might be tight, limiting the dorsiflexion and putting more strain on the fascia as the foot moves into toe off.
