Baryon

We know about quarks. The combination of three quarks made a sub-atomic particles that is called baryon. Baryon is an element of hardon family. Just like baryon, messon is also a member of hardon family.

The word baryon comes from greek. Baryon means heavy. When it was named as baryon then it was higher mass than most of the existed elementary particles.

Baryon is special types of quark based elementary particles that participates in strong interaction, though another quark based particles lepton do not participate in strong interaction.

8 years of one direction

One direction is one of the world famous musical group. Very good news is that One Direction reached in 8 years

What makes you beautiful is a famous song of one direction

Black body

Black body is a physical body that can absorb all kinds of electromagnetic radiation. The unique properties of black body is that it emits radiation in thermal equilibrium so called black body radiation. Emitting of black body radiation is followed by planks law.

Ideal black body have two unique properties

It is an ideal emiter. Emit radiation of any frequency.

It is a diffused emitter. It emit isotropically, that is independent with direction

Straight line geodesic

Geodesic

Geodesic is a term comes from the word geodesy that means the measure the size and shape of earth. Geodesic is a shortest route between two point on the surface of earth. According to geometry, Geodesic is a generalized notion of a straight line to curved spaces.

In general theory of relativity, geodesic is more important. Here curvature geodesic is more considerable than straight line geodesic. The motion of free falling test particle is described in General theory of relativity by geodesic.

Breast Cancer

Breast cancer is a condition of abnormal cell division of breast tissue. It is one of the most common cause of women death worldwide. Besides of Cervical cancer, Breast cancer is a serious disease in women.

Symptom of breast cancer

The common symptom of breast cancer is lump in breast, changing shape of breast, excretion of fluid from the breast nipple. Another symptom of breast cancer may be bone pain, yellowish color of skin, shortness of breath.

Risk factor of developing Breast cancer

The risk factor of developing breast cancer is hormone replacement therapy, Alcohol, ionizing radiation, obesity and lack of physical exercise. Basically, the responsible gene for breast cancer is BRCA 1 and BRCA 2. These are the inherited gene spread from generation to generation.

Chaos theory and catastrophe theory

Chaos theory in mathematics is associated with nonlinear dynamics that describes objects that looks random but exactly not and usually follows determination to describe.

On the other hand Catastrophe theory is an way of abruptly change of continuous function, which we may termed as discontinuity.

Some example may be introduced,

Nature of arrythmia is an application of chaos theory.

History of wheel and advancement of civilization with science

The invention of wheel take an influencial effect on advancement of modern civilization.

Once a day it was very difficult to think something heavier object to carry from one place to another place. It was also very difficult to communicate with other people who is very apart or distance.

For the realisation of this problem to solve people things to invent wheel and tp make life easier.

Force

Force

The mathematical relationship of force and mass is as follow,

F = ma

Where m is for mass, a is for acceleration and F is for force.

According to Newton laws of motion,

Force is proportional to the rate of change of momentum.

In general view, we can say force is something that tends to changes the existing position of objects. It tries to displace the objects.

Object should be static object or dynamic object. What will be the behavior of these two kind of object?

The first law of motion,

If external force is not exerted then static object will remain static and dynamic object will remain dynamic.

Hence, it is clear that to make motion of any stationary object there need force. On the other hand to stop any dynamic object there need force.

From the equation F = ma, we find force is related with acceleration. Acceleration is the rate of change of velocity.
