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. 
  • ...15 more annotations...
  • 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.

Heroes of Capitalism: Milton Bradley - 1 views

  • began to work on making an American board game similar to an imported game he had played with friends. This new game used a top that spun to indicate the number of squares to move, a first in American board games. Bradley was also the first to redefine the purpose of the board game. In his first game, The Checkered Game of Life, Bradley continued the tradition of using the game to impart moral advice to those playing, but he also defined success in the game by looking at how much wealth each player was able to create and obtain.
  • Bradley found success when he used his troubled business to print copies of this new game. Within two days, he sold all the copies he had printed and sold another 40,000 copies of the game in the first year alone.

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.

Air conditioning - Wikipedia, the free encyclopedia - 0 views

  • Air conditioning (often referred to as aircon, AC or A/C) is the process of altering the properties of air (primarily temperature and humidity) to more favourable conditions. More generally, air conditioning can refer to any form of technological cooling, heating, ventilation, or disinfection that modifies the condition of air.[1]
  • An air conditioner is a major or home appliance, system, or mechanism designed to change the air temperature and humidity within an area (used for cooling and sometimes heating depending on the air properties at a given time). The cooling is typically done using a simple refrigeration cycle, but sometimes evaporation is used, commonly for comfort cooling in buildings and motor vehicles. In construction, a complete system of heating, ventilation and air conditioning is referred to as "HVAC".
  • Air conditioning can also be provided by a simple process called free cooling which uses pumps to circulate a coolant

  • he heat pump is added-in because the temperature of the storage gradually increase during the cooling season, thereby declining in effectiveness. Free cooling and hybrid systems are mature
  • The basic concept behind air conditioning is said to have been applied in ancient Egypt, where reeds were hung in windows and were moistened with trickling water. The evaporation of water cooled the air blowing through the window, though this process also made the air more humid (also beneficial in a dry desert climate). In Ancient Rome, water from aqueducts was circulated through the walls of certain houses to cool them. Other techniques in medieval Persia involved the use of cisterns and wind towers to cool buildings during the hot season. Modern air conditioning emerged from advances in chemistry during the 19th century, and the first large-scale electrical air conditioning was invented and used in 1902 by Willis Haviland Carrier. The introduction of residential air conditioning in the 1920s helped enable the great migration to the Sun Belt in the US.

  • Chewing gum is a sweetened, flavored confection composed primarily of latex, both natural and artificial. Organic latex, a milky white fluid produced by a variety of seed plants, is best known as the principle component of rubber. Used as a snack, gum has no nutritive value, and, when people have finished chewing, they generally throw it away rather than swallow it.
  • The most successful chewing gum company ever is that established by William Wrigley, Jr., in 1892. Although the company, run by the founder's son and grandson after his death in 1932, developed a wide array of flavored gums, it dropped many of these to concentrate on its biggest sellers: "Juicy Fruit," "Doublemint," and "Wrigley's Spearmint." Recently, the company introduced gum for denture wearers, sugar-free gum, cinnamon-flavored gum, and non-stick bubble gum. Like earlier Wrigley products, all have proven popular. The secrets behind the success of Wrigley gums—the company has never made anything else—are strong flavor and prominent advertising. As William Wrigley, Jr., said early in the century, "Tell 'em quick and tell 'em often."

  • The Puget Sound Engineering Council selected Russell as the 2005 Industry Engineer of the Year. And despite all of his accomplishments, it wasn't until Joe Decuir of Seattle's chapter of the Institute of Electrical and Electronics Engineers, Inc., (IEEE) saw a story about Russell in the local newspaper that he suggested Russell's name to the committee last fall.
  • In the mid 1950s, he was frustrated with the sound quality of LPs, which started wearing out after only a dozen plays. He even tried using a cactus needle to play records because the jewel needle wore out the vinyl faster and didn't sound as clear. Russell wanted a way to capture the complexity and nuances of classical music without damaging the recording. And the idea that sparked a multi-billion dollar industry was about to take shape in Russell's mind.
  • In fifth grade, he started building radios out of parts he scrounged from the neighbors. In high school, he took a job setting up a commercial radio station, even though he didn't know how to hook up most of the equipment. "But I learned– rapidly,” he laughs.

  • After graduating from Reed College with a degree in physics in 1953, Russell took a job with General Electric in the Hanford Nuclear Plant doing experimental work.
  • Battelle took over the Hanford Laboratories in 1965 and gave Russell a lab and time to work on some of his imaginings, including the crazy idea that sound could be converted to strings of numbers and reproduced using light.
  • He had come up with a way of using a laser to read digital bits of information, which later became the most widely-used way to read just about everything. By using a light to read the data, the record would never wear out. The data are encoded as microscopic pit marks on the surface of the disk, which, when spun, can be read to reproduce high-quality sound.
  • The original goal was to record television shows, not music, because adding visuals would be more difficult. If television couldn't be recorded digitally, Russell and his backers decided they would at least know where they stood. In 1973, they were successful, but they were ahead of their time. Amazingly, no one wanted to buy a license for the precursor to the DVD.
  • By 1991, about 25 years after he came up with the idea, CDs were outselling their predecessors, audio tapes, in record stores nationwide.
  • But all he can do is shrug ruefully, "I didn't invent the CD, I invented the technology.”
  • Today, Russell has more than 50 patents to his name. He continues his work from the basement of his Bellevue home where he and Barbara have lived for more than a decade.
  • The first devices were called Optical Digital Data Storage –the term CD is actually a trademark of Philips. The original storage units were made of glass plates, about the size of large index cards, which could be read as a laser scanned over them.

Molecular Expressions: History of the Compact Disc - 0 views

  • History of the Compact Disc Starting in the mid 1980's, compact discs (CD) began to take over both the audio and computer program market. Much of this can be attributed to a general acceptance of certain specifications regarding compact discs, known as the "Color Books." Originally designed and developed by both Sony and Phillips, the concept of the Color Books was patented and standards were developed. These are a collection of five books that describe the specifications and standards CD technology follows. This led eventually to the current audio CD technology (Figure 1).
  • The first book, written in 1980, was named the "Red Book" and outlined the specifications regarding CD Digital Audio. This was the common CD used in stereo systems, and was capable of holding up to 99 tracks, for a total of roughly 74 minutes of audio information.
  • The second book was written in 1983 and is known as the "Yellow Book", comprising the basis of the Compact Disc - Read Only Memory (CD-ROM). This became the standard for computer-based compact discs, and meant that any computer system that had a CD-ROM drive, could read this format. It is capable of holding around 650 million bytes of data. CD-R's were developed under the same standards, but the actual CDs were comprised of different material. While the generic CD-ROM discs uses aluminum in their construction, the CD-R discs uses gold, which makes color a distinguishing feature.
  • ...6 more annotations...
  • The third book, known as the "Green Book," covered CD-Interactive technology, is used to synchronize both audio and data tracks on a CD-ROM in order to provide things such as full motion video combined with interactivity. Published in 1986, Phillips Interactive primarily marketed this technology.
  • The fourth, the "Orange Book", is merely an outline for the coming generation of writable CD technology, primarily CD-E. (Compact Disc - Erasable) This is meant to replace, or be used in the same matter as floppy discs, only providing a much larger medium to store data. The technology is available today, but know otherwise as CD-RW. (Compact Disc - ReWritable) Much like a floppy disc or hard drive, data can be written and rewritten to these discs, allowing for a very large yet portable medium of data storage.
  • The last book known as the "White Book," is a plan for the future of compact disc technology. It outlines what is known as video compact discs, and contains the standard of data compression that is used to display large amounts of audio and video on a home computer. This concept more or less morphed into what is now known as DVD (Digital Video Drives,) a technology produced primarily by Sony, Phillips and Toshiba. While not compatible with the standard CD-ROM drives used in computers, it did achieve what the White Book had outlined for the future.
  • While an overview of how compact disc technology developed and became so popular is presented, it fails to explain how the technology works. There are, however, relatively simple processes accounting for how a compact disc is read and how the CD-ROM drive translates that into data your computer can understand. First is the construction of the compact disc. It is built from a layer of polycarbonate plastic, covered in a color-dyed layer of aluminum, and followed by a protective layer of lacquer. Figure 2 shows a cross section of a compact disc, illustrating the different layers and providing a general idea behind its construction.
  • When a compact disc is written to, tiny rivets are made in the surface of the disc called stripes or pits. The areas between these pits are called lands, which together make up a pattern where data is written. From there, a CD-ROM drive uses a read head to interpret these patterns, which is done by focusing a laser beam on the surface of the disc. While the CD is spinning, this laser comes in contact with the lands and pits. If the laser comes in contact with a pit, the light is reflected off in all directions. However, if the light comes in contact with a land, it reflects back into the read head, triggering an electric impulse. Figure 3 illustrates the difference between a land and a pit, and how the light is reflected in each situation.
  • A pattern is developed from these electric impulses, and the CD-ROM drive returns this pattern to the computer as a string of 1s and 0s. This binary or digital data is in turn interpreted by the software controlling the CD-ROM drive, and then translated into something the computer can use, be it an executable program, an image, or a sound file.

Creative genius : Edwin Binney | The Simbos - 0 views

  • When people think of the most creative companies of the twenty-first century, they think of revolutionary companies like Apple and the creative giant behind the brand, Steve Jobs. Edwin Binney wasn’t quite the Steve Jobs of his time. But his products have had a far longer shelf life than any Apple product so far. His little company started out making industrial colorants which still doesn’t sound too creative. But from those products, Binney had a vision. He saw a need in the market, specifically among children, and he converted his business to meet that need. He began manufacturing wax crayons, packed in little boxes, for children to use at school in a time when crayons were expensive artists’ tools. Combining two French words, his wife Alice names the little crayons “Crayola.”
