While not everyone will have pondered the subject while staring out of the window during a flight, the question as to why aeroplane windows have rounded edges, unlike the hard corner in your home is interesting.

Over the years, aerospace engineering has made huge leaps in aeroplane technology, meaning planes can carry more passengers and go faster. The planes have also changed shape to increase safety – including the windows. As commercial air travel took off in the mid-20th century, airline companies began to fly at higher altitudes to save money—the air density is lower up there, creating less drag for airplanes. However, higher altitudes came with problems, like the fact human beings can’t really survive at 30,000 feet. To make that possible, the cabin was changed to a cylindrical shape to support the internal pressure. But at first, plane builders left in the standard square windows and this expansion meant catastrophe.

The de Havilland Comet came into fashion in the 1950s. With a pressurised cabin, it was able to go higher and faster than other aircraft. However, the plane had square windows and in 1953 three planes fell apart in the air, killing 43 people in total. The reason for the crashes? The windows. Where there’s a corner, there’s a weak spot. Windows, having four corners, have four potential weak spots, making them likely to crash under stress – such as air pressure. By curving the window, the stress that would eventually crack the window corner is distributed and the likelihood of it breaking is reduced. Circular shapes are also stronger and resist deformation, and can thus survive the extreme differences in pressure between the inside and outside of the aircraft.

Fortunately, designers figured out the design flaw pretty quick. Now we have nice, rounded airplane windows that can withstand the pressure of cruising altitude. Gives being able to gaze out of your window to the world from 35,000 feet a whole new outlook, doesn’t it?




The first biochip was invented by an American company namely Affymetrix, and the product of this company is GeneChip (DNA microarrays). These products comprise the number of individual DNA sensors used for sensing defects. Biochip plays an essential role in the field of biology research like systems biology as well as disease biology while the number of clinical applications is rising. It is a set of microarrays which are placed on a strong surface of a substrate to allow thousands of reactions to be performed in less time. The development of biochip mainly includes the combination of molecular biology, biochemistry, and genetics. Biochips are used for analyzing organic molecules connected with a live organism. This article discusses about a Biochip, its types,their uses, disadvantages, and its applications.

What is a Biochip?

A biochip is a set of diminished microarrays that are placed on a strong substrate that allows many experiments to be executed at the same time to obtain a high throughput in less time. This device contains millions of sensor elements or biosensors. Not like microchips, these are not electronic devices. Each and every biochip can be considered as a microreactor that can detect a particular analyte like an enzyme, protein, DNA, biological molecule or antibody. The main function of this chip is to perform hundreds of biological reactions in a few seconds like decoding genes (a sequence of DNA).

Working Principle of a Biochip:

The working of Biochip mainly includes the following steps.
  1. Step1: The operator generates a low-power electromagnetic field through radio signals
  2. Step2: The fixed biochip gets turn on
  3. Step3: The activated chip transmits the identification code reverse to the operator through radio signals
  4. Step4: Reader strengthens the received code to change it into digital form and finally exhibits it on LCD.

Components of BioChips

The Biochip comprises two components namely the transponder as well as reader.

1) Transponder

Transponders are two types’ namely active transponder and passive transponder. This is a passive transponder which means that it doesn’t contain any of its own energy or battery whereas in passive, it is not active until the operator activates it by giving it a low electrical charge. This transponder consists of four parts such as antenna coil, computer microchip, glass capsule, and a tuning capacitor.
  • The computer microchip stores a unique identification (UID) number that ranges from 10 digits to 15 digits long.
  • The antenna coil is very small, primitive and this type of antenna is used to send and receive the signals from the scanner or reader.
  • The charging of the tuning capacitor can be done with the small signal i.e, 1/1000 of a watt which is sent by the operator.
  • The glass capsule holds the antenna coil, capacitor, and microchip, and it is made with a biocompatible material namely soda lime glass.

2) Reader

The reader comprises of a coil namely “exciter” and it forms an electromagnetic field through radio signals. It offers the required energy (<1/1000 of a watt) to activate the biochip.  The reader carries a receiving coil for receiving the ID number or transmitted code sent back from the excited implanted biochip.
Types of Bio chips

1) DNA Microarray

A DNA microarray or DNA biochip is a set of tiny DNA spots fixed to a strong surface. A researcher utilizes to calculate the expression levels for a large number of genes. Every DNA mark comprises picomoles of particular genes which are termed as probes. These can be a short segment of a genetic material under high rigidity situations. Usually, probe-target hybridization is noticed and counted by recognition of fluorophore or chemiluminescence labeled targets to decide the relative quantity of nucleic acid series in the target. Innovative arrays of nucleic acid were macro arrays about 9 cm X 12 cm and the initially automated icon based analysis was published in the year 1981.

2) Microfluidic Chip

Microfluidic biochips or lab-on-a-chip are a choice to usual biochemical laboratories and are transforming several applications like DNA analysis, molecular biology procedures, proteomics which is known as the study of proteins and diagnostic of diseases (clinical pathology). These chips are becoming more complex by using 1000’s of components, but those components are designed physically called as bottom-up full-custom plan, which is a very large workforce.

3) Protein Microarray

A protein microarray or protein chip method is used to follow the actions as well as connections of proteins, and to find out their function on a large scale. The main advantage of protein microarray is that we can track a large number of proteins in parallel. This protein chip comprises of a surface for supporting like microtitre plate or bead, nitrocellulose membrane, the glass slide. These are automated, rapid, economical, very sensitive, consumes less quantity of samples. The first methodology of protein chips was introduced in antibody microarrays of scientific publication in the year 1983. The technology behind this chip was quite easy to develop for DNA microarrays, which have turned into the most generally used microarrays.

Biochips Advantages and Disadvantages

The advantages of biochip include the following.
  • The biochip is used to rescue the sick
  • Very small in size, powerful and faster.
  • Biochips are useful in finding the lost people
  • Biochips can be used to identify the persons individually
  • Biochips perform thousands of biological reactions in a few seconds.
The disadvantages of biochip include the following.
  • Biochips are expensive
  • Biochip raises dangerous problems of individual privacy.
  • Biochip marks the end of human being liberty and self-respect.
  • There will be a chance of turning every person into a controlled person
  • Biochips can be fixed into the human’s body without their interference.

Biochips Applications

The applications of biochip include the following.
  • By using this chip we can trace a person or animal anywhere in the world.
  • This chip is used to store and update the information of a person like medical financial and demographics.
  • A biochip leads to safe E-commerce systems
  • These chips are effective in restoring the records of medical, cash, passport, etc.
  • The biochip can be applicable in the medical field as a BP sensor, glucose detector, and oxygen sensor.
From the above-discussed information finally, we can conclude that biochips are accurate, fast, and miniaturized. The biochip space lies at the intersection between chip manufacturing, molecule biology, genomics, and signal processing. The market for Biochips and its applications has been increased in a number of core research regions. 

Master these technical and soft skills to ensure continued professional success.

Technologies are changing so rapidly that today’s cutting-edge developments will be old news by tomorrow. So how do engineers in various fields keep up in such a mercurial environment? Engineering is a domain where one’s training never ends, even after years of professional schooling. Developing a set of critical technical and soft skills is critical for keeping up with the latest engineering developments.
Here are 10 technical and “soft” skills to focus on:

Technical Skills

Computer science fundamentals. Learning computer science fundamentals and programming is not just for computer science engineering grads anymore. All engineers should devote some time to learning computer technology, even those studying fluid power or mechanical engineering. An engineer should be familiar with data structures, algorithms, and computer memory manipulation to be ready for any engineering career. Engineers should consider participating in programming hackathons and practice problems to hone their IT skill.
Data modeling. This skill helps engineers estimate datasets’ underlying structures to identify useful patterns. It also helps in identifying correlations between data, data clusters, and so on, which can be used to detect anomalies and regressions. One key aspect of data modeling is the continual evaluation of a given model’s integrity using classification or regression measures. This is often combined with strategies such as split testing and randomized cross-validation to identify errors, tweak the model, and apply algorithms.
Probability and statistics. The field of probability and statistics is closely entwined with machine-learning algorithms. These algorithms, when applied with various statistical parameters such as variance, median, and mean, can remove data uncertainties. Using a blend of these techniques, engineers can build and validate viable models from observed data. In essence, machine learning algorithms are extensions of statistical data modeling procedures.
System design. This skill lets engineers understand how small components fit into a larger system of products and services. Creating a system of component interfaces—where each piece connects and communicates with the other via database queries, library calls, and REST APIs—requires an intelligent system design. A carefully-articulated design prevents bottlenecks and lets algorithms handle varying volumes of data. System design is backed by software engineering best practices that include requirements gathering, version control, testing, modularity, and documentation.

Soft Skills

Leadership and management. Taking on responsibility and preparing to eventually lead a team is a valued skill for engineers to have. Leadership and management skills are extremely important if you want to succeed at team management. The good news is that leadership skills can be learned via training, observation, and practice. Learning when to mentor, when to give space, when and how to discipline, how to use a team-member’s strengths, and acquiring other people skills should be a goal for every engineer.
Communication. Communication skills are two-fold. The first deals with explaining concepts to clients and managers and translating from the technical to the mundane. The second involves giving instructions to team members and other players without rubbing anyone the wrong way. It’s critical that engineers gain the ability to give excellent client presentations and write clear-cut, non-ambiguous reports and e-mails. Engineers need to practice communication skills if they want to excel at interactions with clients, colleagues, teammates, and management.
Commitment and desire to learn. Engineers must demonstrate their desire to learn and their ability to commit to a plan. Young engineers may not understand the seriousness of staying committed, but they soon learn that without this skill, the other skills don’t matter. Commitment also means absorbing new technologies and keeping updated on your industry. Engineers help themselves when they show they can work effectively within the industry and improve it.
Critical thinking and problem-solving. Engineering is rife with situations that require diligent problem-solving. Engineers must be able to approach every task and problem with a cool, unemotional, analytical mind. They need to solve all aspects of a problem while taking minimum risks. Problem-solving is an engineering process in which where each solution is tested and modified. It is often necessary to test several solutions before deciding which is best.
Attention to detail. Engineering projects are often complex and engineers they must consider a myriad of details, right from the concept and the problem-solving phases to the modeling and the testing phases. They need to focus and pay close attention to detail to ensure nothing critical gets lost in the process. In fact, the success or failure of any project often hinges on serious attention to detail.
Giving and receiving feedback. Paraphrasing and updating John Donne, the 16th Century English poet, “No one is an island, especially in the field of engineering.” Engineers have to work as part of a team, so it’s important to be able to give and receive feedback without seeing red. Engineers must understand their team just as well as they understand their projects. As one software boot camp instructor puts it, “Providing honest, kind, and actionable feedback when working in teams is only possible if you have empathy. And the skill of giving and receiving feedback is more often than not the key difference between successful and unsuccessful projects.”
There are several other soft skills engineers should have, such as interpersonal and collaborative skills, creativity, and flexibility. The important thing, however, is the ability to realize that a single person cannot design an engineering marvel. It takes a team. And it takes a special skill to work effectively with people of greater or less talent. All other soft skills are part of this overriding one.

  • Newton’s Third Law of Motion states, “When one object exerts a force on a second object, the second one exerts a force on the first that is equal in magnitude and opposite in direction.”
  • This law is sometimes called the “Law of Action and Reaction”.
    • Even though the forces are equal in magnitude (strength) and opposite in direction, they do not cancel each other.  This law addresses two objects, each with only one force exerted on it.
      • Each object is exerting one force on the other object.
      • Each object is experiencing only one force.
    • The action and reaction forces are reciprocal (opposite) on an object.
      • Examples may include:
      • A swimmer swimming forward:
        • The swimmer pushes against the water (action force), the water pushes back on the swimmer (reaction force) and pushes her forward.
      • A ball is thrown against a wall:  
        • The ball puts a force on the wall (action force), and the wall puts a force on the ball (reaction force) so the ball bounces off.
      • A person is diving off a raft:

        • The person puts a force on the raft (action force) pushing it, and the raft puts a force on the diver (reaction force) pushing them in the opposite direction.
      • A person pushes against a wall (action force), and the wall exerts an equal and opposite force against the person (reaction force).
      • The Space Shuttle engines push out hot gases (action force), and the hot gases put a force on the shuttle engines (reaction force) so the shuttle lifts (there is no sling shot doing it!)


Einstein’s name has become synonymous with genius and creativity. Named Person of the Century by TIME in 1999, Einstein is a rare icon, whose wisdom extended far beyond the realm of science to reveal a man with an almost childlike sense of wonder and a profound love of humanity.

The Internet, Social Media and Texting (an activity that requires cell phone usage) are some of the greatest novelties of our time. As technological wonders, they are ‘game changers’ in both peoples’ private and public lives. State and local governments depend upon them to run smoothly. And they have opened up new avenues for conducting commerce across continental barriers and ocean bodies. By the same token, the widespread use of these technologies has also caused many businesses to flourish. Popular ISP initiatives like the Spectrum Double Play and Rhode Island Internet projects deserve special mention in this respect. Though these examples are by no means exhaustive.

A Little Bit of Both Sides of the Debate

But these modern necessities have largely arrived with a paradox in the making. As per one perspective, they make the world a smaller place. The popular arguments pertaining to globalization and free trade deal with this concern at length. And if you didn’t already know this, you can find many research papers online that vent on this subject. Heck, you’ll probably be able to pen a dissertation of your own after you’re done reading even two of these complicated manuscripts!
According to another understanding, these technologies have made the world a larger place. This side of the argument requires more exploration. So in this blog post, I’ll try to provide an explanation on exactly how this is so. And I promise that in a moment’s time, you’ll see what I mean.

How the World has Actually Become Bigger?

The Internet projects a virtual reality all of its own. Its globally-spanning network connects computers with each other, and in turn people. For many individuals, this reality has become much more immediately accessible than what their mundane existence offers.
Think about it.
On a purely psychological and emotional level, the real world is a scary place. Full of people who seek to do you wrong along every turn. And then there’s the element of a deep-rooted hypocrisy, which reeks from even those people who are normally considered ‘well-meaning’. To top everything off, there’s the fact of limited resources (that are fast depleting) paired off with the concern of many mouths to feed. A situation which is also sometimes referred to as the ‘economic problem’ in business school textbooks.

Some Natural Questions that Arise…

Why would anyone in his (or her) right mind want to deal with such a bleak world? One where negativity, in all its unappealing forms, is prevalent in almost every direction that one turns to. And where goodness (in all its beautiful and rejuvenating forms) is fast turning into an impractical concept. A way of life reserved for only those of us who aren’t strong enough to become tyrants in their own right!
All of these are probably the reasons why a lot of people have limited their social contact with one another. And in doing so, they’ve embraced the virtual world maintained and advanced by the web. We can think of social media as the interaction space of this arena. While personal computers, mobile phones, tablets, and pocket pagers are the tickets that provide access.
And what happens when these two worlds (the real, and the created) run side-by-side to each other?
They gradually start to merge into one.
Setting up a larger world order than the one our ancestors imagined. Or thought could be possible one day.

A New World Order in the Making

The ‘internet-reality’ (as some scholars call it) has created a lot of distances, while it has bridged others. In this regard, the popular influence of social media is an area of special interest for many researchers.
Social media platforms like Facebook and Instagram are well-known, today, for creating ‘thought bubbles’. These are imaginary and creative fields of fixed ideas; occupied by people who become their staunch defenders. And who maintain an almost religious devotion to their continued maintenance.
This issue came into full relief during the 2016 U.S Presidential Elections. The followers of the Trump campaign supported strong ultraconservative and ultranationalist views. Regarding their lives, their faith, their country, immigration, and government. The same ideals upheld by far-right political elements all across the globe.
Similarly, fans of the Clinton campaign championed strong liberal and globalist views. Many of which fell (and continue to do so) in sharp contradiction with the other camp. The heated debate surrounding abortion rights and government spending is a key talking-point for these people.
Recently, I signed into a number of online American political forums with my Spectrum internet Deals connection. And (like many people looking at things from the outside), I wasn’t really surprised to see the thought bubbles working in full swing. With each trying to stall the advance of the other – by any legitimate, as well as other, means possible.




The internet is not as free as you may think. Consider yourself lucky if you happen to live in a liberal nation where there is no censorship on the internet yet. But this isn’t the case for people living in China where the internet gets worse every year. China has the most rigid and extensive censorship program in the world as of now. Let’s know more.

How Does China Censor The Internet?

The Chinese Government can control what its citizens see on the web using their censorship program called “The Great Firewall”. This program limits access to foreign websites completely bans most of the high-ranking foreign sites, and can also block particular keywords when they are entered in search engines. Moreover, the Golden Shield system is set up for domestic surveillance and continuously monitors the web activities of the citizens of China.

Websites Blocked In China

Some of the popular foreign websites that are blocked in China include the following:
  • Facebook
  • Gmail
  • Google
  • Twitter
  • Blogspot
  • Youtube
  • Instagram

Future Plans of China

Up till now, to access foreign websites, Chinese citizens had the option of using a VPN network which could bypass the censorship of “The Great Firewall” and allow unfettered access of any website (with some slowdowns and crashes). However, in the coming months, it is possible that China will completely block access to such virtual private networks also. This drastic move will have serious repercussions for all the business developers and companies in China who will have a hard time sustaining themselves globally.

Other Countries That Block the Internet

China isn’t the only country that censors the internet for its citizens. Other countries that control the internet include Cuba, Saudi Arabia, Russia, Pakistan, Vietnam, and some more.

Why Do These Countries Censor the Internet?

Internet censorship in many countries is increasing by the day as the governments want to have a tight grip on what the citizens of the country are posting or reading on the net. The rationale behind this censorship is so that the citizens don’t indulge in any untoward religious or political debates thereby opposing their government and causing social/political unrest.

Censorship is a double-edged sword. While the absence of it may lead to chaos, using it for suppressing dissent isn’t correct either.
