Nanotechnology – what is hidden by this term?

Nanotechnology is term that makes some people feel nervous and others be optimistic for the future. Yet when the technology is actually made into a reality one set of people will consider their views justified and the others will not. Nanotechnology was envisaged as a means of making machines that were so small that they would be made up of molecules. Nanotechnology when the term was first used in the 1980’s seemed to offer the prospect of revolutionizing the ways some medical, industrial and technological things could be carried out. The question has to be asked, what is hidden by this term?


In many respects, in theory at least there little that can be hidden by using the term nanotechnology, That is because the term explains itself even to people with only a limited knowledge of science and technology. The theory is simple enough to grasp, using micro production techniques in order to produce molecular sized tools to carry out specific tasks, which larger pieces of equipment would be far too large to use for. These remote and or radio controlled devices can do things or reach places that no other tools, or pair of hands could do. Whilst the theory of nanotechnology was simple to understand, it proved harder to achieve in reality. Nanotechnology had to wait for improvements in computers and electronic microscopes to become a reality.


However nanotechnology is a term that can hide the fact that it is a technological advance that could be used for evil or immoral purposes, even though that is contrary to the reasons for developing it in the first place. The intention behind this technology was to make the world a better place, not a more dangerous one. Yet it can be used to develop things like biological and chemical weapons, either in secret by governments, or by terrorist groups. Medical research techniques using nanotechnology can be used for harm, and terrorist groups will have no qualms in using such weapons once they have successfully made them.


There are military uses for nanotechnology too, though these are not particularly hidden by using the term either. Weapons could be given greater precision, or the ability to be accurately targeted by the use of technology. Making weapons could be effective using the technology as well. Again the military in countries across the globe could use it to develop biological and chemical agents to attack enemies with.


However the majority of purposes that nanotechnology are used for do not have to be hidden at all. It is used for medical research that develops cures and treatments for illnesses such as cancer. The technology has been put to really good use in carrying out surgical procedures. This key hole surgery has meant that surgeons have been able to operate on more patients than before, and to successfully treat more conditions than had previously been the case.

Further more nanotechnology means that such small tools can be made to make miniature components for compact technological items such as phones and tablets.

Energy Sources of the Future – How Will We Power Our Homes

In current times, we primarily use electricity as our energy source for many home appliances. This power comes mainly from power stations that burn gas and coal to produce that electricity. The same goes for personal home electricity sources such as portable generators, which rely on mainly on gasoline. When it comes to our vehicles we also burn petrol that is produced from oil. It is a well known fact that burning fossil fuels releases CO2 into the atmosphere, which is the cause of global warming. If this trend persists, the world’s coal reserves will get depleted in roughly two hundred years, the natural gas reserves will get depleted in 60 years, while the world’s oil reserves will deplete in 40 years. With an increasing world population, our current energy demands increase while our energy sources diminish.

However, there is a solution for our future energy demands; natural energy sources. These are inclusive of sun, wind, water, wood fuel, sea power, and geothermal heat. These natural energy sources cannot be depleted. As an additional advantage, they are a clean source of energy since they produce minimal greenhouse gases in the endeavor to produce electricity.

In terms of portable energy sources, choosing a piece of equipment calls in several variables. For example, if that piece of equipment is a portable generator or some other power supply unit, variables will include, size, noise, output, endurance, among other factors. However, most variables will get defined based on that equipment’s application, hence, simplifying your choice. At this point, we would like to discuss some of the most promising energy sources of the future.

The very first is Biomass Energy. Crops such as wheat are fermentable and can produce ethanol which is then burnt to generate electricity or otherwise used to propel vehicles. Ethanol and biodiesel are already used as fuels in some new motor vehicle versions. The advantage of these types of fuel is that they are carbon-neutral; meaning that the carbon dioxide that is emitted is in perfect balance with the carbon dioxide that plants use.

Another promising energy source of the future is Hydroelectric Energy. Hydroelectric power is produced from flowing water. Flowing water can be found in the form of rivers or otherwise manmade structures such as dams. This source of energy is also clean since it does not generate any carbon dioxide and because it uses no fuel resources, it is impossible to deplete. Additionally, it also meets peak energy demands because of its capacity for flow regulation.

Also, there is Nuclear Energy that produces a quarter of the UK’s electricity as we speak. Nuclear energy uses Uranium as its fuel in the production of electricity. Nuclear power plants only need require to be refueled once in every two years, hence, they do not depend on conventional fuel sources to stay operational. They also produce a minimal amount of carbon dioxide; therefore, they do not contribute to the global warming phenomenon. There have been very few accidents, but in the event of one, the outcome could be adverse because of nuclear waste which is extremely hazardous. This is the only potential disadvantage of this form of energy.

Another source of our future energy demands is Wind Power. Wind power uses propellers, known as turbines to capture wind and propel them for the purpose of generating electricity. This is one of the safest forms of renewable energy with zero carbon dioxide emissions. In addition, these turbines can be built on a small scale that can be used as a portable energy source as long as they are positioned in an open and windy area.

Finally, there is the more common Solar Energy. The solar cells on solar panels convert sunlight into energy. This is a non-depletable and safe energy source since it produces no amount of carbon dioxide and, therefore, does not contribute to global warming.

The above mentioned are the most promising sources of energy for the future. These sources of energy cause our planet minimal to no harm and if implemented immediately can slow down the depletion of the world’s natural energy resources and keep our world healthy at the same time.

5 Inventions We Are Looking Forward to See in 2016

Inventions and innovations will always be part of the package every New Year brings to humanity. Many of the inventions are inclined towards making lives easier and better while of course others will always prove detrimental to human existence. Inventions are often based on pre-existing needs and also on the improvement of pre-existing inventions. The fact about inventions is that they are set in a very competitive world, so the deal always gets better upon every new release.

The year 2016 comes as no exception and many are the innovations to expect from the world of technology and artificial intelligence. There are already smart devices existing to which major changes will be made to affect human lives and activities from the state-of-the-art laboratories to the corporate world. Here are some of the top five innovations that may be part of what many are interested in:

1) A wider variety and spectrum of wearables.

The years prior to 2016 have seen engineers develop gadgets that have played a great role in reducing the need for the portability of larger devices such as laptops. Top developers of wearables have come up with smart watches and other wrist gadgets that have proved to be of great use while on the move. The year 2016 is expected to see the development and rise of more efficient gadgets with a broader spectrum of activities for which they can be utilized for.

2) The advent of more complex transport systems

The field of transport has evolved quite majorly since the invention of the wheel which happened very many years ago. Each invention has sparked up another and there have been major achievements including the very popular aero plane invention by the Wright brothers. Getting to the twenty first century, the flying has been quite revolutionized with other flying objects used for transport being major products realized and others still being in prospect. 2016 should be a year to expect a new release of a complex transportation means and their production on large scale.

3) More from the world of artificial intelligence

Artificial intelligence has been a pillar in the revolution of almost every aspect of the human lives on their day to day activities. Technology companies all over the world have been on an unceasing and competitive streak to bring the best products for human utilization. There has been the advent of voice recognition which in turn has been a pillar for the creation of many smart devices. The face recognition and other related identification measures have been other major inventions that have helped play a major role in security. There is major the major anticipation of better security systems revolving around AI in 2016. Also in the field of smart devices, we expect to see inventions that will see the simplification of life in the living environment of people who own smart homes.

4) Drones

The military and industries have much to thank engineers for due to their creation of the drones which have been great game changers in the battle fields and in the control and reporting of industrial processes. We expect to get more from the makers of the drone with the spectrum of activities that they can handle, in 2016.

5) Interconnectivity of things

Over the years, technology companies have worked to create a suitable environment for the interconnectivity of devices in which human beings have been able to share information or remotely access other devices. 2016 should be a year to see the advent of a brand new mode of interconnectivity to outdo the existing ones.


5 Inventions Which Prove Nikola Tesla Was The Greatest Inventor Ever

Nikola Tesla, genius Inventor, was often misunderstood and deliberately persecuted by his competitors and the government. Thomas Edison was the most famous of those that attempted to undermine Tesla’s greatness, and in a way, Edison won because he is better remembered in the history books. However, the real greatness was all Tesla’s, and here are 5 Inventions that prove it.


  1. Alternating Current:

AC/DC, not simply a band, actually are the two kinds of currents used to power objects by electricity. Direct current was Edison’s invention, and alternating current, a far safer and cheaper option, was Tesla’s, and it currently powers North America.

  1. Radio:

To those who are saying Marconi invented the radio, the Supreme Court overturned his patent in 1943 when Tesla Was proven to have invented it years prior, even applying for his own patents.

  1. The Electric Motor:

There is a good reason the electric sports car was named for Tesla. Only the beginning of the first World War prevented his invention from becoming widely known.

  1. Remote Control:

One of Tesla’s patents was for the first remote control boat. From this has come many other Inventions, from toys to weapons. Most tools that are created for mankind at some point are turned to harmful purposes, but the positive developments still hold great value despite this.

  1. Lasers:

One of the greatest Inventions, yet another with harmful and beneficial uses. The advancements in surgery alone make this an invention of limitless value, yet people will create the ray guns soon enough.


Sadly, Nikola Tesla died penniless and virtually unknown in 1943, his work largely suppressed by corporations and the government. His work was seized upon his demise, by the United States Government, although much recently was released due to the Freedom of Information Act. His work deserves recognition in this modern era, giving him the respect in death he was too often denied in life.


5 Reasons Why You Should Study Physics at Caltech

Name of the Institution: California Institute of Technology

Do you fancy giddy successful career as the researcher in Physics? Are you proud of your recent scientific achievements and awards? In this case, you can strive for becoming the member of Caltech community.

Today, California Institute of Technology or Caltech is included into the list of Top 10 research universities and is fiercely competing with the Massachusetts Institute of Technology (MIT) for the right to be regarded the first-rate technical university worldwide.

Brief history

Caltech was founded in 1891 by local businessman and philanthropist Amos Troupe and was initially called Technological University. In fact, it was a simple vocational school. Everything changed crucially in 1907 in Pasadena, a small town in the vicinity of Los Angeles. The astronomer named George Hale came to the city and headed the local observatory and decided that a small Pasadena school could become the center of scientific thought the United States.

Arthur Noyes and physicist Robert Millikan were the pioneers in the bubbling researching life of the school. Both researchers became professors at Caltech, and in 1923, Millikan won the Nobel Prize in Physics, which only added to the university points. From an ordinary technical educational institution, Caltech turned into a respected scientific research center and prestigious university.

What are the Five Reasons to Study Physics at Caltech?

1) First and foremost, Caltech is a multi-university making an accent on the set of mandatory courses in physical sciences. Thus, the institution provides excellent training in basic subjects for the students of Physics Department. Furthermore, this is the most reputable and prestigious specialty at Caltech.

2) At Caltech, you can get a diploma of higher education in the US with a Bachelor’s, Master’s or Doctoral degree (PhD). Doctorate in Physics obtained at Caltech is a very significant line in the job, and, as a rule, its owners strive for an academic career.

3) Caltech’s physics faculty, scientists, and students are working at the forefront of the fields of theoretical and applied physics, exploring the fundamental laws of nature and applying their insights and discoveries to help us better realize the natural phenomena that exist throughout the Universe.
