Our essential post-it
The history of the known Post-it is also part of this list of random discoveries.The researcher Spencer Silver, who worked at the 3M company was trying to improve acrylate adhesives. What he discovered was actually an adhesive “formed itself into small spheres and could not stick very strongly”. But what could serve?
Art Fry, another 3M researchers resolved this issue through a personal frustration. Tired of the paper separator pages is constantly falling, thought the Silver adhesive could be used to build sticky notes . A less curious story, linking the chance with a practical application widely used in our daily lives.
The blue pill to treat angina pectoris
Drug research is characterized by sometimes be the most fortuitous and surprising. As with penicillin, the history of sildenafil (better known as Viagra) is the less special . In 1985, the pharmaceutical company Pfizer was working on a drug to treat angina and hypertension.
When they started clinical trials, they found that sildenafil did not meet the expectations expected. However, increasing the dose to the maximum, they saw that there were several side effects (headache, indigestion, visual problems, muscle aches and … oddly enough, a change in erectile function).
Pfizer researchers found that the new drug could be used in patients with impotence. The rest of the story is known to all sales of the famous millionaire blue pill and a tremendous commercial success important for this company.
Burned rubber to a tire company
We are known as vulcanization process whereby crude rubber is heated in thepresence of sulfur, in order to harden it and make it resistant to cold. This manufacturing process was discovered by accident by Charles Goodyear in 1839.
Four years later he would patent his invention and in 1853, in an autobiographical book, tell your experience. Interestingly, the famous company Goodyear tires was not founded by the discoverer of vulcanization of rubber, but by Frank Seiberling, who used the name of the company as a tribute to theinventor by chance one of the products most commonly used today in things such as balance bike reviews.
LSD: It all started in childbirth
Albert Hoffman was a chemist who in the late thirties worked trying to purify the compounds produced by the ergot, so use it and prevent bleeding that occur after childbirth.
Thus he managed to isolate lysergic acid diethylamide, and working with this new compound in his laboratory, ingested by accident, after falling a drop in her fingers. Hoffman told in an interview that “was in the lab and began to feel strangely dizzy, saw how the colors changed, his mood too, had the impression that to her personality had changed.” In other words, the chemical performed “first trip” unwillingly , before LSD was psychedelic drug known famous in the sixties and seventies.
This invention was worthy of the Nobel Prize for Physics in 1901. Wilhelm Conrad Roentgen was working on experiments with cathode rays and random thanks, he watched a cardboard sheet (impregnated with cyanide Pt-Ba) showed fluorescence.
Röntgen spread it among the scientific community and there was even a liar who crossed him. However, the publication of an article of his in the British Medical Journal , which attached one of the first films in which a broken arm looked , served for his discovery and potential diagnostic use is believed. Curiously, the scientist called his discovery “X – ray” because I knew very well their origin.
Graphene: The material that came from the heat
The discovery is known as a material of the future is the less curious. In 2004, physicist Andre Geim worked at the University of Manchester, looking for a new line of work for a doctoral student. As another of his students he worked in graphite, and to make surfaces that are smooth and clean as possible are needed, they used to get a very rudimentary system.
How are clean and smooth surfaces are obtained? The method is quite archaic, as stick a piece of tape on the surface, and pull hard. So get started the more superficial layers, and then analyzed the remaining graphite. Zeal tapes used previously discarded without further. However, Geim it occurred to investigate what was left in the heat , and what happened was amazing. The tapes previously pulled, monolayers were crystalline graphite, in other words, graphene.
The properties of this material are causing a real technological revolution today.This latest invention from the list of discoveries by chance is of such importance that was the reason Geim and his student received the Nobel Prize in Physics in 2010.
There are many more discoveries random apart from that we have had today.Inventions like Velcro or Teflon products used in medicine as the first anticoagulants and other applications are part of this set of serendipity that changed history.
Undoubtedly, events that happened by chance, but whose practical application would not have been possible without the causality and the ongoing work of its inventors.
