The quantity h, now known as the Planck constant, is a universal constant with the approximate value of 6.626 X 10^-34 Js. Max Planck assumed that the radiation energy is emitted in discrete packets called quanta rather than in a continuous way. The energy E of the quantum is related to the frequency Î½ by E = hÎ½.

Headaches Frequent headaches can be another sign that you are anemic. In the context of a blood disorder, however, headaches usually indicate that there is a lack of oxygen reaching the brain. When this happens, the arteries in the head start to swell, causing pain.
Often the symptoms are not related to the bowel function, but instead are due to the consequences of chronic malabsorption of vitamins and minerals (for example, people who complain of weakness, fatigue, and are anemic because they cannot absorb iron in the diet).
