10 Scientific Inventions

Science has been always kind to man kind since ages. The world’s history is full of innovations, inventions and scientific discoveries and the work is not over yet. We have collected some basic scientific inventions from different sources on the web and numbered it from from 10 to 1. See the Top 10 scientific inventions that changed the way man think, starting from number 10;

10- Invisibility Cloak




It sounds like something straight out of a comic book or Hollywood movie special effect, but invisibility cloaks are a new scientific discovery that is poised to begin happening very shortly. The studies look at ways to make light bend around an object, so that it no longer appears to be visible. The applications of this technology are endless, from use in military defenses to use with cell phones and other wireless devices

9- Large Hadron Collider


Although discoveries from the past are enticing and help us see from where we’ve come, it is the discoveries of today that are most exciting. The collider was built as a probe into subatomic particles. Many have high hopes for this collider that it will help us to one day understand the speed of light and to find ways to travel through time and space. The machine sits on the Swiss and French border. When they first fired up the Hadron Collider, they had high hopes, but a malfunction caused the machine to be shut down and is now being repaired.

8- Radio Waves




Heinrich Hertz was the first person to discover radio waves in 1888, although others before him had predicted that the waves were there. An inventor, Guglielmo Marconi, was so fascinated with Hertz’s discover that he invented the Marconi Transmitter. These first machines would eventually lead to the development of Morse code and S.O.S. as a distress signal. Today, there are thousands of radio stations transmitting across the airwaves, Internet companies running on sound wave frequencies and many other everyday applications that are a direct result from these first inventors’ investment of time.

7- Penicillin


Although this wonder drug was discovered earlier in the century, it was not widely available until the 1940s. Dr. Alexander Fleming accidentally discovered penicillin. He noticed that some mold stopped bacteria from growing and after years of research by many people the drug was developed into what it is today. Before the discovery of penicillin, even minor infections could result in death.

6- Computer


Who on earth invented the computer anyway? This isn’t a question that can really be answered easily. There were a lot of different people involved along the way. We’ve certainly improved upon the initial invention, which filled up an entire room to today’s teeny computers that can fit in items as small as cell phones and other devices. In 1936, the Z1 computerwas created and is often credited as being the first computer. One thing is certain, the computer will continue to get smaller and improve in the number of functions it can perform.

5- Light Bulb


Back in 1879, Thomas Edison invented a little thing called a light bulb. This bulb would revolutionalize the way that people handled dusk each day and expand daylight hours for people all over the world. Today, the light bulb is as common as a slice of bread. Talking about top scientific inventions is certain to bring up the name of Thomas Edison. After all, he invented many of the scientific discoveries that we use today or the precursors to those inventions, such as the phonograph and motion pictures. He also improved upon many inventions.

4- Fingerprints



The discovery that fingerprints are unique to each individual, are left behind on objects a person touches and can be lifted off those items is nothing short of miraculous. This discovery completely changed the way that law enforcement conducted investigations. In today’s modern age, Jack the Ripper would eventually be caught. Even though it was 1823 when Jan Evangelista Purkinje noticed how unique our fingerprints are, it took some time for law enforcement to figure out ways to use this knowledge. Today, this discovery is used in everyday police work

3- Electricity


Without Benjamin Franklin and his penchant for kites, electricity might not have ever been discovered. Without electricity, you wouldn’t be reading this Top 10 list, because there would be no computers and no Internet. Many of our everyday functions would be changed drastically. Many different schools and websites discuss the history of this element that we take for granted.

2- DNA


Deoxyribonucleic Acid, or the mapping of the human gene, is probably one of the greatest discoveries in medicine. By learning more about how genes are put together, doctors are developing medications to treat any number of diseases and ailments, including diabetes. There is some debate over who in the world actually discovered DNA, but the truth is more complex and involves contributions from quite a few talented and brilliant scientists. Many feel that Rosalind Franklin does not get credit where credit is due for this discovery.

1- Anesthesia


Imagine a world where instead of gently drifting into oblivion before a surgery, you were wide awake for the entire procedure. Although the term itself was created by Oliver Wendell Holmes in 1846, poppy seeds were used as a type of anesthesia back in pre-historic times. There are many different types of anesthesia, including herbal anesthesia. Learn about the differences between general anesthesia, local anesthesia and deep sedation.
