A new scientist reported that U.S. researchers used nanoparticles to ‘smell’ the scent of illnesses in fluids of the body. The researchers used nanoparticles of gold with different coatings so that they can distinguish among different proteins and could be able to detect the illness.
As said by Vince Rotello from the University of Massachusetts the human nose has got a series of receptors, which react differently to different compounds. Thus the receptors do not react to a specific smell, but it is a generalized response produced by the receptors, that creates the smell.
Vince Rotello made a team with his colleagues from the university and with scientists from the Georgia Institute of Technology, and then he applied the same ‘nose-principle’ to detect proteins.
The ‘nano nose’ is a system of six receptors, each one consisting of a solution with gold nano particles which are not larger than 2 nanometers, each one having a different coating too. Nitrogen atoms form the organic molecules which develops the coating of the nano particles.
If I will do this, then this will happen, and if i do this differently then that may happen. Yes, it is what we all keep doing. We all try to define our future steps by planning things and then thinking that this will happen in the end. But what we lack is we see things with our strength and ability. We forget that some people posses ‘can do attitude’ and once they decide to do something, they continue working on it until they get success.
Same is true in technology world as well. Many people from technology world has been predicting, but most of the predictions were cause of a laugh when that time came and prediction turned false. Following is a list of 30 best predictions which never came true. Lets know about them.
1. High speed Rails
Dr Dionysys Larder (1793-1859) predicted that
“Rail travel at high speed is not possible because passengers, unable to breathe, would die of asphyxia”.
Dr Dionysys was a professor of Natural Philosophy and Astronomy at University College London.
2. Making of a Ship against Wind
When Napoleon Bonaparte was told of rober Fulton’s steamboat in 1800, his statement was
“How, sir, would you make a ship sail against the wind and currents by lighting a bonfire under her deck? I pray you, excuse me, I have not the time to listen to such nonsense.”
3. Railroads is a bad system
Martin Van Buren, Governor of New York, in 1830 wrote to the president that
“Dear Mr. President: The canal system of this country is being threatened by a new form of transportation known as ‘railroads’ … As you may well know, Mr. President, ‘railroad’ carriages are pulled at the enormous speed of 15 miles per hour by ‘engines’ which, in addition to endangering life and limb of passengers, roar and snort their way through the countryside, setting fire to crops, scaring the livestock and frightening women and children. The Almighty certainly never intended that people should travel at such breakneck speed”.
4. Telephone has Shortcomings
It was printed in a memo at Western Union in 1878 ( or may be 1876) that
“This ‘telephone’ has too many shortcomings to be seriously considered as a means of communication. The device is inherently of no value to us”.
5. Electric Light will Close as well
Oxford professor Erasmus Wilson predicted that
“When the Paris Exhibition [of 1878] closes, electric light will close with it and no more will be heard of it”.
Today, we can’t expect life without electricity.
6. British Post don’t Need Telephone
It seems British were not believing on fast communications. In 1878, British Post Office gave a statement that
“The Americans have need of the telephone, but we do not. We have plenty of messenger boys”.
How backward thought they were having.
7. X-rays will be nothing but a Hoax
In 1883, the president of Royal Society Mr Lord Kevin stated that
“X-rays will prove to be a hoax”.
8. Alternating Current – A waste of time
Thomas Edison was an American inventor. In 1889 he commented that
“Fooling around with alternating current is just a waste of time. Nobody will use it, ever”.
Edison was fond of passing ridiculous arguments against his competitor George Westinghouse for AC power.
9. Impossible Flight of Machines Heavier than Air
“Flight by machines heavier than air is unpractical and insignificant, if not utterly impossible.”
This was predicted by Simon Newcomb. The prediction turned false when The Wright Brothers flew at Kitty hawk 18 months later.
10. Very Poor Energy by an Atom
Ernest Rutherford predicted that
“The energy produced by the breaking down of the atom is a very poor kind of thing”.
He gave his statement just after splitting the atom for the first time. He further stated that
“Anyone who expects a source of power from the transformation of these atoms is talking moonshine.”
11. Submarine will do Nothing
HG Wells was a British novelist. In 1901, he stated that
“I must confess that my imagination refuses to see any sort of submarine doing anything but suffocating its crew and floundering at sea”.
Wish he was still alive to see how submarines are playing a role in defense of a country.
12. Automobile will Never Replace Horse
We can see how automobile has replaced horses. But in 1903, the president of Michigan Savings Bank advised Henry Ford’s lawyer not to invest in Ford Motor Co. According to him,
“The horse is here to stay but the automobile is only a novelty – a fad”.
This means he was not trusting on mechanical engineering at all.
13. Transmitting voice across the Atlantic
In 1913, Lee DeForest sold the stock of his Radio Telephone Company by making a prediction that
“It would be possible to transmit the human voice across the Atlantic before many years”.
14. People want to see flesh and blood
In 1916, Charlie Chaplin, the actor, producer, director and studio founder, stated that
“The cinema is little more than a fad. It’s canned drama. What audiences really want to see is flesh and blood on the stage”.
It has been proved that audience is more interested towards love stories
