How Science Can Benefit the World?

Most of us don’t take science seriously and think that is doesn’t matter much, but this is something which is completely incorrect. Science has the power to affect our everyday lives, from the moment we wake up till the end of the day. Everything around is related to science in some or the other way; be it the digital clock in the room, or the weather report we see on our phones, or the decision to bake some cookies or just turning off the lights at night, everything is there and happens courtesy science. The modern world we stay in today would not have been possible and that modern, without the knowledge and use of science.

Science and it innovations

Science is responsible for basic technological innovations that affect our daily lives, and also for a number of complex devices like the computers, x-ray machines and phones. Everything from flu vaccines to tools for performing open heart surgeries, are there because of science, so our life is impacted to a large extent by technology.

Ways in which science affects our lives

  • Electricity- So had science not been there, it would not have been able to understand electricity and its uses well. Science has helped us in giving a better understanding of electricity and its uses, because of which we are able to talk to one another over the telephone, watch entertainment channels and are able to switch off and on the light whenever required.
  • Plastic- Chemistry helped in developing different plastics for different jobs, like dental floss and blocking of bullets, which are used till now.
  • Agriculture- Science has changed the way we cultivate our lands and the stuff we eat. With the development of fertilizers, pesticides and insecticides, it has become easy to harvest more food. Science is also responsible for the ‘green revolution’ that has brought a striking change in the field of agriculture leading to a massive increase of food.
  • No medicine- Proper understanding of science has led to the development of modern medicine required for a lot of deadly diseases, which can cause death. Eradication of small pox, prevention of nutritional deficiencies and cancer treatments, all are possible today because of the modern medicine.
  • Prediction of natural disasters- Though it is not always possible to predict the disasters but scientists do know effective ways of predicting most of them. There may be issues in giving out warnings but with science you can analyse the data and make the right and timely decision in case of a disaster.

Science undoubtedly is important to the world and can benefit the society in a number of ways. It would not be wrong to say, that had science not been there; even our daily chores would have become impossible to complete and we would not have been living in a peaceful society. Science is crucial for our lives, and we are targeted by science related policies in our everyday lives, so understanding science and its significance is very important.

What is Nano Technology?

Nanotechnology is defined as the manipulation of matter which has at least one dimension that is sized from 1 to 100 nanometres. There is a wide use of nanotechnology in various fields. They have already been used in different products and also play an important role in various industries.

The various applications of nanotechnology:

  • Nano composites: Nanotubes and nanoparticles are widely used in composites. The materials that combine one or more separate components which are designed to exhibit the best properties of each component. This multi – functionality will apply not only to the mechanical properties but also to the other magnetic, optical and electrical properties. The carbon fibres and bundles of the multi – walled CNTs are being used in polymers which are used to enhance or control the conductivity. Making use of the individual CNTs in the composites is a potential long – term application.
  • Nano lubricants: The Nano spheres of the inorganic materials can be used as lubricants, which can act as Nano sized ball bearings. The controlled shape is considered to make them more durable as compared to the conventional solid lubricants and wear additives. It is also considered that this type of a lubricant is quite effective even if the metal surfaces are not very smooth. In this nanotechnology application, the particles would be dispersed in a conventional liquid lubricant. Also the design of the lubricant system needs to include measures to contain and then also mage the waste.
  • Nano paints: when Nano particles are being incorporated into paints, they help in the improvement of their performance which makes them lighter or can also give them the other required properties. The thinner coatings of the paint that are used on the aircraft would help in reducing their weight which can prove to be a great advantage to the environment. There could also be reduction in the solvent contents of the paint which can be beneficial to the environment. Anti–fouling surface treatment is also considered to be valuable in the process applications. This could include the heat savings, this can lead to the savings of energy.

What are the advantages of nanotechnology?

  • Manufacturing advantages: nanotechnology has already been making new materials that could help in revolutionize many areas in manufacturing. The nanoparticles and nanotubes are composed of materials that are very light and very strong which have insulating properties.
  • Energy advantages: there can be transformation which is made by nanotechnology in which energy can be obtained and used for various purposes. Nanotechnology will make solar power which will be more economical as it helps in reducing the cost of construction of solar panels and all the other related equipment. The energy storage devices will become more efficient.
  • Medical advantages: nanotechnology has great potential and can make great advances in the field of medicines too. Nano bots can be sent into the patient’s arteries which can be used in clearing away the blockages. Apart from that surgeries can also be done faster and more accurately.
