What is physics

Physics is the study of how things work. Physics seeks to explain the basic interactions of matter and energy. It studies matter, motion, space, and time. Generally, it is the scientific analysis of nature in order to try to understand how the universe behaves

It is the science that for centuries was called Natural Philosophy. Over the years, it has branched into specialties such as mechanics, properties of matter, heat, astronomy, sound, electricity and magnetism, light and optics, atomic and nuclear, relativity, astronomy, quantum mechanics, and many others. One can specialize in these narrower areas of physics as one wishes. Introductory courses usually review the various fields to show how concepts of matter, energy, power, and time interconnect.

Applied Physics is generally called engineering. The branch of science concerned with the nature and properties of matter and energy. The subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms.

How do chemicals affect the environment

They can both help and hurt the environment. Some chemicals are necessary such as water, minerals, and the air we breathe. The exact effects depend on the exact chemicals. Some chemical waste can harm plants, wildlife, or even humans. Some chemicals such as phosphates can cause excessive red algae to grow in bodies of water. Oil and petrochemicals in the water can kill birds and fish.

What is leukemia

Leukemia (also spelled Leucamia, or leukaemia) is an umbrella term for cancer of the blood-forming tissues or bone marrow, characterized by the production too many blood cells. While most people associate leukemia with an excessive number of white blood cells, certain forms of the cancer produce too many immature red blood cells.

There are four main types:

1. Acute lymphocytic leukemia (ALL)

2. Acute myelogenous leukemia (AML)

3. Chronic lymphocytic leukemia (CLL)

4. Chronic myelogenous leukemia (CML)

Both forms of myelogenous leukemia are more common in adults; acute lymphocytic leukemia is the most typical form seen in children.

ALL, the most common cause of death from disease in children, is characterized by rapidly forming immature red blood cells that have a short life cycle. This causes them to crowd the bone marrow, making it impossible to produce healthy red blood cells.

Chronic leukemia, on the other hand, is caused by the slow build up of mature, abnormal blood cells that have a longer-than-normal life span. As a result, the body tends to produce too many new white blood cells.

According to the Leukemia and Lymphoma society, the five-year survival rate for all types of leukemia is approximately 54%; survival rates for lymphocytic leukemia is considerably higher than average, particularly in children.

Leukemia is a type of cancer that affects the bone marrow, the soft, spongy center of the bone that produces blood cells.
