Acoustic Cloaking Technologies – What Else Can We Use That For?

One of the holy grails of military research has to do with the ability to cloak sound. Imagine how important it is to have a silent running aircraft, helicopter, vehicle, submarine, or ship. After all, if the enemy can hear you a mile away approaching in a helicopter, they have more than an ample amount of time to get a shoulder launched surface-to-air missile ready to fire at you. However, if you can sneak up without making any sound, it’s too late, you win, they lose, or you fly over without being shot at – the enemy’s opportunity is gone.

Stealthy submarines need to remain undetected if the submarine is to survive in battle, or be any good. There was an interesting article in the BBC Science section recently on June 24, 2011 titled; “Acoustic ‘Cloaking Device’ Shields Objects from Sound” by Jason Palmer (science and technology reporter). The article stated that;

“The device makes objects invisible to sound waves. Acoustic cloaking was theoretically in 2008 but no exists. Barrowing many ideas from attempts to “cloak” objects from light and using simple plastic sheets with arrays of holes. Could make ships and subs invisible to sonar or used in acoustic design of concert halls – it is mostly based on metamaterials which are designed to force light waves to travel around an object; to an observer, it is as if the object were not there.”

Is it possible that we are finally reaching an age where we can not only cloak ourselves from radars using stealth technology, but also acoustically cloak our military assets, and the sound they produce? Re-diverting sound within a cavity inside of an aircraft means that you can operate jet engines without noise. Not only will radar not be able to see them, but you won’t hear them coming or going either. Likewise, such a system could protect people from the ultrasound noise which is made from wind turbines.

Wouldn’t it be nice to sleep if you lived next to a freeway if you had some way to prevent the sound from getting in? Something like this could change everything. Those living near airports wouldn’t have to worry anymore, and schools near airports wouldn’t have to stop every time an airplane flies over. I know about that because I grew up on military bases as a kid. The ability to acoustically cloak sound has incredible secondary applications, and it might make a very good transfer technology once it is used worldwide. Indeed I hope you will please consider all this and think on it.

What Is Your Role In Maintaining Technological And Scientific Development?

The world relies on scientific and technological developments and progress. It is therefore understandable why science and technology go hand in hand. The field makes life easy through innovative ideas and inventions that offer much needed solutions to different issues that affect daily living. Without science and technology, it would practically be impossible for world developments to be reached. The world would not be where it is now without the strides made in science and technology. This is the field that gives rise to scientists, engineers and even doctors among others. They are all professionals very crucial in taking the world higher and improving the quality of life.

The truth is that technology and science developments must be maintained. It is through this that the already existing inventions and innovations will become better and new ideas reached to make life even better. The global future relies on such developments and education can offer the much needed solution in the field. So what is your role in making sure that such important developments are maintained for the global need and benefit?

Play your role in science and technology: This revolves around finding out what you are good at as far as science and technology is concerned and taking a path in that direction. Your natural abilities, ideas and innovations can make a whole difference to the world and its future. When you get an education, it becomes easy to realize what you are most passionate about and you also find a way of making your ideas transform into realities that won’t only benefit you but the world at large. This is one of the most important things that you can do to ensure that the development of science and technology is maintained.

Reach out to others for the same: In case you cannot offer your individual expertise, innovations or ideas, what about reaching out to others who have the potential to make a change? This is most possible through educating children who can be the engineers and inventors that the world needs as far as science and technology is concerned. Even though most world children have access to quality education and become who they wish to be, a huge number is not that privileged. In this group of less fortunate children could be the next scientist to make it possible to explore mars or doctor to find a cure to diseases that are yet to get cured.

By reaching out a helping hand to the less fortunate through donations, you will be playing an important role of maintaining the important developments. There are lots of nonprofit organizations dedicated to offering children the quality education they need in science and technology through equipment donations. They include anatomy models, microscopes, computers, physics kits, chemistry kits and other general equipment. You can equip a child through donating to such worthy causes and make a difference in the future. Monetary donations can also be made to make it possible for the organizations to get the needed equipment to the less fortunate.

Science Fair Projects – What’s In It For Me?

So it’s time for science fair projects again. Many students dread these assignments, but there is really no need to panic. For the elementary grade levels, you could do something as easy as growing a crystal garden. But for middle or high school science fair projects, you will probably need to do something that involves more scientific research and experimentation, using the scientific method. Science fair projects should be fun and interesting, and when you are done you will have learned something new to share with your friends and family.

One of the best things about doing science fair projects is that they are not like doing homework. You get to pick the topic, ask the questions, and design the experiment. When you analyze the results, there are not necessarily any right or wrong answers. Many kids find that it is much more fun than doing schoolwork.

Picking Science Fair Project Ideas

It doesn’t have to be hard finding science fair projects ideas. As a matter of fact, just look around and see if something in the world around you could use some improvement. Or, ask yourself “What am I interested in?” and go from there. Turn that interest into a question and then find a way to answer it. Choosing science fair topics really can be that simple and easy.

Now maybe you would like to do something different or more unusual, but you are having a hard time finding just the right idea. There are many places you could look. You could start at the library. Or search the internet to find all kinds of cool ideas to try. There are many sites that list science fair projects and ideas, as well as give you instructions on how to design and perform your experiment.

Why Do Science Fair Projects?

There are lots of great reasons for doing science fair projects. For example, global warming is a big issue in the world today. Doing a science fair project in this area not only helps you to learn, but could help the whole world. That can be very exciting. Some students actually end up making new or important discoveries. Today, more than ever, doing a science fair project could be a way to contribute to the world around you.

What are some of the other good reasons for doing science fair projects? Many different people will see your science fair project display, learn about your idea and the work you put into it. You can win prizes such as money, a trip to another state or country (maybe even with all the expenses paid), or a scholarship to college to further study your own interests. Science fair judges are often important scientists or industry leaders. Gaining their recognition could lead to a job or internship doing what you love. For instance, in the technology field, you could work on a new computer program that will help a local business in your community.

By doing science fair projects you will learn a lot about yourself, your talents and gifts, and what you like to do. You will learn how to ask questions and find a solution. You can learn to work on your own or with people of various ages, sharing ideas and doing the research to reach a conclusion. You can earn respect and recognition from family, friends and your community. You can also learn how to communicate better with those around you. And of course, you will learn about the scientific method, performing valid experiments and analyzing the results. These are all are important life and job skills you will need as an adult. The future of the world lies in the fields of math, science and technology, and you can make an important contribution by using your abilities and imagination, all starting with your science fair project.
