Science In Everyday Life

Science has influenced each and every aspect of man’s life. Wonders of science are uncountable machines and gadgets invented and made with the help of science are ubiquitous.
Humans searching for a cure for various serious diseases  With science And inventing things Whether used in medicine  Industrial plants and houses Must use science. Such as, cancer treatment  Then have to do chemotherapy treatment, those devices will come from the experiments of science before actually being used.
Pertain to pollution toxic fumes coming out of chimneys can be turn into non-polluting substances using science.
Medical science have invented so many wonder drugs. The effects of these drugs are so wonderful. When you take medicine  will help to relieve the symptoms.
Machines;example, machine that are designed to check DNA , when putting both blood in a test tube drop a little mixture. The imported material will get DNA result. This is the science in everyday life that we often see.
Science is helping man find cure for deadly diseases. Science has the potential to solve all of man’s problems and challenges provided it is put to right use.

Status of Matter

The status is a group of physical systems that are visible to the naked eye, which is related to the chemical structure and physical properties such as density, crystal structure, refractive index.
Solid is the state of matter which has a unique characteristic. That is resistant and resistant to deformation and the changes in the volume itself are arranged in close proximity to each other. The bond between the particles is very valuable. Solid particles cannot move but will shake a bit because there is very little space between molecules the solids cannot flow like liquids. And not compressed like gas most solids are crystalline. Arranged With exact geometry many forms at the micro level.
The liquid is a fluid state in which the volume is limited under constant conditions of temperature and pressure, and its shape is determined by the container containing it. Moreover, the liquid exerts pressure on the side container and something in the body of the liquid itself this pressure will be passed in all directions.
Gas in conditions where temperature and pressure are appropriate many substances change to solid state, liquid or gas. Non-metallic elements such as hydrogen fluorine, oxygen, nitrogen, inert gas and covalent compounds with low molecular mass, such as CO, CO2, NH3, have gas status at room temperature. Normally, gas usually refers to a substance that has a gas chamber at room temperature. The liquid substance at normal condition but being changed gas is called vapor. Gas has very little bond between particles the particles are very far apart when compared to liquids and solids, so when filling gas in containers the gas therefore spread full of containers. Make the shape change according to the size and shape of the container Gas has a lower density than solid and very liquid. Can compress to reduce the volume.
The substance in nature has 3 states as follows.
1. Solid particles are aligned together Particles cannot move Making the particle bond strength higher than in other states of the same substance With the exact shape and volume Not dependent on containers Examples of solid state substances such as iron, aluminum, copper, silver.
2. The liquid particles are slightly apart. Allowing particles to move Uncertainshape Change according to the container But the volume does not depend on the container Examples of substances with liquid status such as water, alcohol, bromine.
3. The gas particles will be apart. Anchor strength is low Can move a lot With volume and shape according to the container Examples of substances with gas status, such as oxygen gas, hydrogen gas, carbon dioxide, nitrogen gas.

Sport Science

  Sports science is a science that studies about exercise for health. To develop the potential and strengthen the muscles and prepare the athletes.
  The sport, the good body of the athlete is extremely important. Therefore, it is necessary to use science to help with the nutrition of athletes. In which athletes must consume foods that are essential to the body that helps to strengthen the meat and food that compensates for the loss of energy during the training of athletes and after the practice of sports.
  Biomedical science is essential to sports science because it helps in the functioning of muscles, bones, ligaments and joints in the body. For analysis Salute to use Effective body movement and energy loss during training and after training to make it easier to allocate nutrition to each athlete.
  The athlete's mind is an important part of the race. Which will help in the planning process during the competition, how to use the plan that will be able to fight the opponent and win the possession And the mental state of the athlete is also involved in the competition Therefore, athletes must have a way to control their minds to be with themselves during training and competition.
  Therefore, science is absolutely necessary in the field of sports. When lack of science will cause athletes to lose good shape Not enough nutrients for the body. Therefore, science is indispensable in the field of sports.

Electromagnetic Wave

electromagnetic wave  Caused by electromagnetic interference  (Electromagnetic disturbance) by changing the electric or magnetic field  When the electric field changes, it induces a magnetic field. Or if the magnetic field is changed, it will induce an electric field
      The characteristics of electromagnetic waves are transverse waves.  Consists of electric and magnetic fields that have perpendicular vibrations  And on the plane perpendicular to the direction of motion of the wave
Electromagnetic waves are waves that move without intermediaries.  Therefore can move in vacuum
            The spectrum of electromagnetic waves consists of electromagnetic waves that have different frequencies and wavelengths.  Which covers from Visible light Ultraviolet, infrared, radio waves, television, microwave, x-rays, gamma rays, etc. Therefore, electromagnetic waves  Therefore very useful in communication and telecommunications And medical

    Properties of electromagnetic waves
no need to use a moving medium. All electromagnetic wave speeds in vacuum are 3x108m / s which is equal to the speed of light. A transverse wave. Transfer energy from one place to another. Being released and absorbed by matter.No electric charge and the waves can be inserted, reflecting, refracting and turning.
      From the study, it was found that electromagnetic waves are useful and also very important for humans.  Whether it is radio communication Using infrared radiation to search for wild animals Which electromagnetic waves are very important

Genetically Modified Plants

   Genetically modified plants (GMOs - Genetically Modified Organisms) are plants that undergo genetic engineering. In order to have specific features or features as needed, such as resistance to pests Resistant to unsuitable environments or increasing the amount of nutrition or biomolecules, such as vitamins, proteins, fats, etc. Genetically modified plants are considered a type of transgenic organism, also known as GMO or GMOs. Advances in biotechnology and molecular biology Especially genetic engineering That has developed rapidly to a very high level What is the driving force for scientists and research institutions around the world Dedicating a lot of energy, ideas and research grants for this science is the aim to improve the quality of life of the world population. Both in nutrition, medicine and public health
​Examples of transgenic plants, such as soybeans, can be obtained from soybeans that are better characterized by bringing genes from bacteria into DNA DNA of soybeans. Making soybeans able to withstand chemicals that can eliminate roundup weeds or glufosinate better than conventional soybeans Resulting in the ability to use roundup chemicals in greater quantities Causing more yield of soybeans as well, from the original knocked out gene that causes saturated fat Making soybeans with less saturated fats, by bringing the gene B gene into the soybean, so that soybeans can kill the insects that are soy enemies
​Transgenic plants The success of such science development There is concrete that is to raise the quality of food, medicine and medical technology. As we receive benefits today And in the condition that the world population increases More every day While the production area has decreased Genetic engineering is one of the best technologies. That will help solve the problem Shortages of food and medicines that may occur in the near future Because of the effectiveness of genetic engineering Can help increase the yield per area higher than traditional production The obvious example is Agriculture in the United States And by genetic engineering Can improve the quality of life Therefore it is said that Genetic engineering is a major revolution in agriculture and medicine, known as genomic revolution. All technologies, when there are advantages, have disadvantages. In the case of GMOs, the disadvantage is There are risks and complexity in Management to ensure safety in order to benefit more than penalty Although there is currently no report that there is Whoever is harmed by the consumption of GMOs, but concerns about the risks of using GMOs are difficult to avoid.
Although there are concerns But be aware that GMOs are one of the most well-cared technologies. As far as humans have invented In Thailand, there are guidelines for biosafety guidelines for researchers at all levels, both at the laboratory level and in field trials, in order to provide GMOs with the highest safety. And is the basis for assessing the risks to humans and the environment. This risk assessment is necessary to continue in each environment. In order to get the information that is all around However, in the case of GMOs, it is a good opportunity for people in the country to be alert and accelerate the maturity, especially the understanding of biotechnology. Which is absolutely necessary Due to any decision The society should be based on understanding of science. And by scientific procedures, that is to focus on the source of information and to check the accuracy of the data Not by fear or by the stream
