Unintended Technology v.s.

Accidental Technology

• A vaccine is a preparation which is used to improve immunity to a particular disease. The term derives from Edward Jenner's use of cowpox ("vacca" means cow in Latin), which, when administered to humans, provided them protection against smallpox, the work which Louis Pasteur and others carried on. Vaccines are based on the concept of variolation originating in China, in which a person is deliberately infected with a weak form of smallpox. Jenner realized that milkmaids who had contact with cowpox did not get smallpox. The process of distributing and administrating vaccines is referred to as vaccination. Since vaccination was much safer, smallpox inoculation fell into disuse and was eventually banned in England in 1848.

Unintended Technology v.s.

By-Product Technology

• A by-product is a secondary or incidental product deriving from a manufacturing process, a chemical reaction or a biochemical pathway, and is not the primary product or service being produced. A by-product can be useful and marketable, or it can have severe ecological consequences.

• Like many of today's great inventions, the microwave oven was a by-product of another technology. It was during a radar-related research project around 1946 that Dr. Percy Spencer, a self-taught engineer with the Raytheon Corporation, noticed something very unusual. He was testing a new vacuum tube called a magnetron (we are searching for a picture of an actual 1946 magnetron), when he discovered that the candy bar in his pocket had melted. This intrigued Dr. Spencer, so he tried another experiment. This time he placed some popcorn kernels near the tube and, perhaps standing a little farther away, he watched with an inventive sparkle in his eye as the popcorn sputtered, cracked and popped all over his lab.

Unintended Technology Examples

VIAGRA• Sildenafil was synthesized by a group of

pharmaceutical chemists working at Pfizer's Sandwich, Kent research facility in England. It was initially studied for use in hypertension (high blood pressure) and angina pectoris (a symptom of ischaemic cardiovascular disease).

• The drug was patented in 1996, approved for use in erectile dysfunction by the Food and Drug Administration on March 27, 1998. It soon became a great success: annual sales of Viagra in the period 1999–2001 exceeded $1 billion.

TEMPUR-PEDIC BEDS

• Tempur-Pedic was founded in 1964 by Dag Landvik, after he was introduced to the viscoelastic mattress concept while in Europe scouting race horses.

• Viscoelastic TEMPUR material was originally designed by NASA for use in space, but after NASA abandoned it, Fagerdala, a Swedish technical foam firm, picked up the idea and made it into a mattress.

BOTOX

• Botulinum toxin is one of the most poisonous naturally occurring substances in the world, and it is the most toxic protein. Though it is highly toxic, it is used in minute doses both to treat painful muscle spasms, and as a cosmetic treatment in some parts of the world.

• In December 1989, BTX-A (BOTOX) was approved by the US Food and Drug Administration (FDA) for the treatment of strabismus, blepharospasm, and hemifacial spasm in patients over 12 years old.

BOTOX

• The cosmetic effect of BTX-A was initially described by ophthalmologist Jean Carruthers and dermatologist Alastair Carruthers, a husband-and-wife team working in Vancouver, Canada.

• On April 15, 2002, the FDA announced the approval of botulinum toxin type A (BOTOX Cosmetic) to temporarily improve the appearance of moderate-to-severe frown lines between the eyebrows (glabellar lines).
