Behind the Wings: Fun Facts About Post-it Notes - 0 views

  • There's a bit in Wonderful World that has to do with Post-it Notes so we did some research into this seemingly ubiquitous office product and learned some fun stuff. Here goes, courtesy of the inventor, 3-M.  - The Post-it Note was invented as a solution without a problem: In 1968 Dr. Spencer Silver developed a unique, repositionable adhesive, but the 3M scientist didn't know what to do with his discovery. Early ideas included a sticky bulletin board for temporary messages, or as a low-powered spray adhesive. Silver kept plugging away at the possibilities of this new glue, presenting it individually and during seminars.
  • Then, six years later, a colleague of Dr. Silver, Art Fry, remembered the light adhesive when he was daydreaming about a bookmark that would stay put in his church hymnal. The rest is history. - Post-it Notes were introduced to the American market in 1980 by the 3M Company. 
  • - A Post-it Note weathered a flight from Las Vegas to Minneapolis on the nose of the plane. It endured speeds of 500 mph and temperatures as low as -56 degree Fahrenheit. - In 1989 a family left a Post-it® Note on their front door during Hurricane Hugo and it was there 3 days later. Their trees weren’t.

Post-It Notes Were Invented By Accident - 1 views

  • There were actually two accidents that lead to the invention of the Post-It note.  The first was by Spencer Silver.  According to the former Vice President of Technical Operations for 3M Geoff Nicholson (now retired), in 1968, Silver was working at 3M trying to create super strong adhesives for use in the aerospace industry in building planes.  Instead of a super strong adhesive, though, he accidentally managed to create an incredibly weak, pressure sensitive adhesive agent called Acrylate Copolymer Microspheres.
  • It did have two interesting features, though.  The first is that, when stuck to a surface, it can be peeled away without leaving any residue. 
  • Specifically, the acrylic spheres only stick well to surfaces where they are tangent to the surface, thus allowing weak enough adhesion to be able to be peeled easily.  The second big feature is that the adhesive is re-usable, thanks to the fact that the spheres are incredibly strong and resist breaking, dissolving, or melting.   Despite these two notable features, no one, not even Silver himself, could think up a good marketable use for it.  Thus, even with Silver promoting it for five years straight to various 3M employees, the adhesive was more or less shelved. Finally, in 1973, when Geoff Nicholson was made products laboratory manager at 3M, Silver approached him immediately with the adhesive and gave him samples to play with.

  • Silver also suggested what he saw as his best idea for what to use the adhesive for, making a bulletin board with the adhesive sprayed on it.  One could then stick pieces of paper to the bulletin board without tacks, tape, or the like.  The paper could subsequently be easily removed without any residue being left on the sheets.  While this was a decent idea, it wasn’t seen as potentially profitable enough as annual bulletin board sales are fairly low.
  • Now enter the second accident by chemical engineer Art Fry.  Besides working at 3M as a Product Development Engineer and being familiar with Silver’s adhesive thanks to attending one of Silver’s seminars on the low-tack adhesive, he also sung in a church choir in St. Paul, Minnesota.
  • One little problem he continually had to deal with was accidentally losing his song page markers in his hymn book while singing, with them falling out of the hymnal.  From this, he eventually had the stroke of genius to use some of Silver’s adhesive to help keep the slips of paper in the hymnal.
  • Fry then suggested to Nicholson and Silver that they were using the adhesive backwards.  Instead of sticking the adhesive to the bulletin board, they should “put it on a piece of paper and then we can stick it to anything.”
  • This initially proved easier said than done, in terms of practical application.  It was easy enough to get the adhesive on the paper, but the early prototypes had the problem that the adhesive would often detach from the paper and stay on the object the paper was stuck to, or, at least, leave some of the adhesive behind in this way.  There was no such problem with the bulletin boards Silver had made because he had specifically made them so that the adhesive would bond better with the board than the paper. Two other 3M employees now entered the scene, Roger Merrill and Henry Courtney.  The two were tasked with coming up with a coating that could be put on the paper to make the adhesive stay bonded to it and not be left behind on whatever the paper was stuck to when it was removed, a task at which they were ultimately successful at achieving. Interestingly, because management at 3M still didn’t think the product would be commercially successful, they more or less shelved it for three years, even though the Post-It notes were extremely popular internally at 3M labs during that span.    Finally, in 1977, 3M began running test sale runs of the Post-It note, then called “Press ‘n Peel”, in a certain areas in four different cities to see if people would buy and use the product.  It turned out, no one much did, which confirmed in the minds of the executives that it wasn’t a good commercial product.
  • Luckily for offices the world over, Nicholson and Joe Ramey, Nicholson’s boss, didn’t feel like giving up yet.  They felt the marketing department had dropped the ball in that they hadn’t given businesses and people samples of the product to use to let them see for themselves how useful the notes could be.  So a year after the initial flop, 3M tried again to introduce the Post-It note to the world, this time giving huge amounts of free sample Post-It note pads away in Boise, Idaho, with the campaign deemed “The Boise Blitz”. 
  • This time, the re-order rate went from almost nothing, in the previous attempt, to 90% of the people and businesses that had received the free samples.  For reference, this was double the best initial rate 3M had ever seen for any other product they’d introduced.  Two years later, the Post-It note was released throughout the United States.
  • So after 5 years of constant rejection for the adhesive and another seven years in development and initial rejection, Post-It notes were finally a hit and have since become a mainstay in offices the world over, today being one of the top five best selling office supply products in the world.
  • Ever wonder why the standard color for Post-It notes is yellow?  It turns out this was kind of an accident as well.  The official story from some at 3M is that it was because it created a “good emotional connection with users” and that it would “contrast well stuck to white paper”.  However, according to Geoff Nicholson there was no such thought given to the color.  The real reason Post-It notes were yellow was simply because the lab next door to where they were working on the Post-It note “had some scrap yellow paper – that’s why they were yellow; and when we went back and said ‘hey guys, you got any more scrap yellow paper?’ they said ‘you want any more go buy it yourself’, and that’s what we did, and that’s why they were yellow. To me it was another one of those incredible accidents. It was not thought out; nobody said they’d better be yellow rather than white because they would blend in – it was a pure accident.”
  • Another obstacle in the initial launch of Post-It notes was that, because it was a completely new type of product, it required the construction of new machinery to mass produce the Post-It note pads, which was initially prohibitively expensive for a product seen by many within 3M as destined for commercial failure.
  • While most Post-It notes only have a thin strip of adhesive, you can buy Post-It notes that are completely covered in the back with the adhesive.  One example of a place this type of note is used is at the U.S. postal service.  These full adhesive backed notes are used there on forwarded mail.
  • Post-It notes received an upgrade in 2003 when 3M launched a new version of the Post-It note with super sticky glue that has better adhesion to vertical surfaces.
  • Spencer Silver holds a total of 22 patents, including the patent for the “low-tack, reusable, pressure sensitive adhesive” used in Post-It notes (Patent#: 3,691,140).  Silver is still working at 3M today in their special adhesives department.  He also has a doctorate in organic chemistry, which he received two years before inventing the adhesive used in Post-It notes.  On the side, his favorite past time is painting using pastels and oils, which he apparently is extremely accomplished at.
  •  Post-It notes are occasionally used in art-work.  One such famous example was in 2008 when Shay Hovell used 12,000 Post-It notes to create a replica of the Mona Lisa.  The most expensive Post-It note art piece was done by R.B. Kitaj and sold for £640 (about $1000) in 2000.
  • Art Fry received his early education in a one room schoolhouse.  He studied chemistry at the University of Minnesota and was hired while still in school at the “Minnesota Mining and Manufacturing Company”, which later was re-named 3M.  He retired from 3M in the early 1990s.

Fountain pen - Wikipedia, the free encyclopedia - 0 views

  • A fountain pen is a nib pen that, unlike its predecessor the dip pen, contains an internal reservoir of water-based liquid ink. The pen draws ink from the reservoir through a feed to the nib and deposits it on paper via a combination of gravity and capillary action. Filling the reservoir with ink may be achieved manually (via the use of a Pasteur pipette or syringe), or via an internal filling mechanism which creates suction (for example, through a piston mechanism) to transfer ink directly through the nib into the reservoir. Some pens employ removable reservoirs in the form of pre-filled ink cartridges. A fountain pen needs little or no pressure to write.
  • liest historical record of a reservoir pen dates to the 10th century. In 953, Ma'ād al-Mu'izz, the caliph of the Maghreb, demanded a pen that would not stain his hands or clothes, and was provided with a pen that held ink in a reservoir and delivered it to the nib, which could be held upside-down without leaking, as recorded i

  • Compact Disk of James Russel The first workable digital compact disc device, the precursor on now ubiquitous CD/DVDs, was invented in the late 1960s by the American physicist James Russell
  • ple to convert into an audible or visible transmission.
  • In 1953, Russell earned his Bachelor degree in physics and graduated from Reed College in Portland. Afterwards he went to work as a Physicist in General Electric's nearby labs in Richland, where his wife Barbara worked as a chemist. At GE, working for the Hanford Nuclear Plant, and appointed as a "designated problem-solver" for GE experimental unit, Russell initiated many experimental instrumentation projects. He was among the first to use a color TV screen and keyboard as the main interface between computer and operator. He also designed and built the first electron beam welder. In 1950s and early 1960s, Russell, who was an avid music listener (he was found of classical music—Beethoven, Chopin, Mussorgsky, Offenbach. etc.), quite frustrated with the wear and tear of his vinyl records and their poor sound quality, tried to improve the record player. Initially he tried using a cactus needle, instead of steel one, for a stylus, but with no success. "After each record you had to resharpen the needle," he recalled.
  • ...6 more annotations...
  • In 1965, the Ohio-based Battelle Memorial Institute opened its Pacific Northwest Laboratory in Richland, to took over management of Hanford's lab, and James Russell joined the effort as Senior Scientist. Thus he gained an audience for his more far-fetched ideas and immediately began to pepper Battelle with proposals for new commercial concepts. The optical digital technology was initially met with skepticism, as it was not believed that one could digitize sound. "Here I was at Battelle, enmeshed in the scientific community, and one of the first things I had to demonstrate was that you could digitize music and reproduce it" he said. "Music into numbers? Come on now, Russell."
  • James T. Russell was born in Bremerton, Washington in 1931. He was always a smart boy and at the age of six he devised a remote-control battleship with a storage compartment for his lunch (obviously the young James enjoyed the food :-)
  • Through the 1970s, Russell continued to refine the CD-ROM, adapting it to any form of data. However, like many ideas far ahead of their time, the CD-ROM found few interested investors at first. In 1971, Eli S. Jacobs, a New York venture capitalist, pioneered the commercialization by forming Digital Recording Corporation to further enhance the product for the consumer video market, and hired Russell and a team of technicians to come up with a video disk. Their efforts led to a 20-minute video disc in 1973.
  • "The vision I had in mind was of television programs on little plastic records. The networks, instead of putting programs on television, would print records. And if you wanted to watch your favorite programs you'd get them in the mail and put in the disk whenever you want," Russell said. "Jacobs thought, if we can do it, hey great, we've got the whole world by the tail. And if we can't, well at least you know where you are." In 1974 Digital Recording Corporation announced an optical digital television recording and playback machine, the first device to digitize a color image, at a Chicago trade show. The response from large potential investors was rather cool. Philips Electronics representatives visited Russell's Battelle lab in the summer of 1975, and they discounted the entire premise of his work. "They said: It's all very well for data storage, but you can't do that for video or audio." recalled Russell. Philips had just released its laser disc, an analog optical video player, and they were convinced that analog was the only way. "Philips put $60 million into development of the laser disc. We were advised that nobody would tell them they had made a mistake."
  • Sony launched its CDP-101—the first commercialized CD player in 1982. Sony and Philips paid royalties from CD player sales to Battelle and to Optical Recording Corporation. Time-Warner and other disc manufacturers settled with the Optical Recording Corporation in 1992, paying $30 million for patent infringement. The court determined that Optical Recording had the sole rights over the technology mentioned in the patents. But because the patents properly belonged to Russell's employer, he never got a cent out of either deal. By 1985, Russell had earned 26 patents for CD-ROM technology. He then founded his own consulting firm, where he has continued to create and patent improvements in optical storage systems, along with bar code scanners, liquid crystal shutters, and other industrial optical instruments. His most revolutionary recent invention is a high-speed optical data recorder and player that has no moving parts. Russell earned another 11 patents for this "Optical Random Access Memory" device.

Inventor Of Cell Phone: 'We Are Just Getting Started' | Here & Now - 0 views

  • Forty years ago this month, Motorola engineer Martin Cooper changed the world by making the world’s first cell phone call. He stood on a New York City street on April 3, 1973, with a 10-inch-long, 2.5-pound phone nicknamed “the brick” and called his engineering nemesis at the much bigger Bell Labs.
  • Cooper’s latest product, which he created with his wife Arlene Harris, is an ultra-simple phone for seniors called the Jitterbug. “I hate the concept of trying to build a universal device that does all things for all people, because then it doesn’t do any of them very well,” Cooper said. “I think what is going to happen in the future is more customization, more personalization. We all are different and we ought to be able to customize and have a phone that does exactly what we want it to do – that is so easy to use that we don’t even have to think about it. That’s what the dream is.”

Montgomery County Daily: Harry Coover Jr., Inventor of Super Glue, Dies at Age 94 - 0 views

  • (NewsCore) - The man who invented Super Glue has died in Tennessee at the age of 94, The New York Times reported Sunday. Harry Wesley Coover Jr., who discovered the super-sticky adhesive by accident during World War II, died of congestive heart failure Saturday night at his home in Kingsport. Inducted into the National Inventors Hall of Fame in 2004, Coover was awarded the National Medal of Technology and Innovation last year by President Barack Obama. Super Glue did not make him rich, however, as it did not become a commercial success until the patents had expired. Son-in-law Dr. Vincent E. Paul said, "He did very, very well in his career but he did not glean the royalties from Super Glue that you might think."

Chewing Gum - American Dental Association - ADA.org - 0 views

  • What is chewing gum? Chewing gum in various forms has been around since ancient times.  The Greeks chewed sap from the mastic tree, called mastiche.  On the other side of the world, the ancient Mayans favored the sap of the sapodilla tree (called tsiclte).  Native Americans from New England chewed spruce sap—a habit they passed on to European settlers.  Today, the base used for most gum products is a blend of synthetic materials (elastomeres, resins and waxes in various proportions).  However, chewing gum is as popular as ever. 
  • What does chewing gum do? The physical act of chewing increases the flow of saliva in your mouth.  If you chew after eating, the increased salivary flow can help neutralize and wash away the acids that are produced when food is broken down by the bacteria in plaque on your teeth.  Over time, acid can break down tooth enamel, creating the conditions for decay.  Increased saliva flow also carries with it more calcium and phosphate to help strengthen tooth enamel. Clinical studies have shown that chewing sugarless gum for 20 minutes following meals can help prevent tooth decay.  In the future, look for chewing gum that delivers a variety of therapeutic agents that could provide additional benefits to those provided by the ability of gum to mechanically stimulate saliva flow. For instance, some gum might contain active agents that could enhance the gum’s ability to remineralize teeth and reduce decay, or enable gum to help reduce plaque and gingivitis.
  • Does chewing gum replace brushing and flossing? No, chewing gum is an adjunct to brushing and flossing, but not a substitute for either. The ADA recommends brushing twice a day with a fluoride toothpaste and cleaning plaque from between your teeth once a day with dental floss or other interproximal dental cleaners.
