Study Notes
Historical Antecedents in Inventions and Innovations
- Fibonacci, a key figure in mathematics, introduced the Hindu-Arabic numeral system to Europe through his book Liber Abaci in the early 13th century.
Tidal Energy and Mills
- Tidal mills utilize the natural rise and fall of tides for energy.
- A dam is constructed at tidal inlets to create reservoirs, allowing water to flow through one-way gates during high tide, which powers water wheels when the tide recedes.
Hourglass as a Timekeeping Device
- The hourglass was necessary for accurate timekeeping in sea travel, as water clocks were affected by ocean motion.
- Before the 14th century, time was measured in unequal hours; however, equal hour measurement became essential for navigation.
Gunpowder Development
- Ancient Chinese Taoist alchemists, in search of an immortality potion, accidentally invented gunpowder around 850 A.D.
- Composed of potassium nitrate, charcoal, and sulfur, its military use expanded during the Tang, Song, and Yuan Dynasties.
Spinning Wheel
- The spinning wheel transformed the production of fibers and paper, previously spun by hand using drop spindles.
- It remains essential in marking paper quality and preventing forgery through manufacturer's marks.
Bifocal Lenses
- Bifocal lenses, invented by Benjamin Franklin in 1784, address both nearsightedness and presbyopia, with a lower section for close-up viewing.
Paper Ring Binders
- Friedrich Soennecken invented ring binders in 1886 to store and protect hole-punched papers.
- These binders typically feature spring-loaded or lever arch mechanisms and are often made from plastic and metal.
Synthetic Plastics
- Leo Baekeland developed Bakelite, the first synthetic plastic, in 1907 as a substitute for shellac, suitable for mass production.
- Bakelite enabled the rise of a variety of synthetic plastics derived from fossil fuels, including polystyrene and nylon.
Electric-Powered Washing Machine
- The Thor, created by Alva J. Fisher in 1908, was the first electric washing machine designed to reduce manual laundry labor.
- Prior inventions included hand-powered machines and washboards, facilitating domestic cleaning tasks.
Insulin Discovery
- Dr. Frederick Banting and his team in 1920 discovered insulin through experiments on dog pancreases, leading to effective diabetes treatment methods.
Barcode Invention
- Norman Joseph Woodland and a partner invented barcodes in 1948 but faced financial struggles; they sold the patent to RCA in 1952.
- The first barcode scanned was on Wrigley’s chewing gum, with commercial use starting after the patent expired.
First Mobile Phone
- Martin Cooper developed the first mobile phone, originally termed “car phones,” at Motorola in 1973.
- Early devices were bulky, had limited battery life, and were significantly heavier than modern versions.
Corning Gorilla Glass
- Corning International created Gorilla Glass in 2007, designed for mobile devices to be lightweight yet tough and scratch-resistant.
- It has improved drop protection, surviving falls from shoulder height more effectively than other glasses.
Human Head Transplant Proposal
- Italian neurosurgeon Sergio Canavero announced a human head transplant project in 2013, aiming for life extension.
- The operation was planned for December 2017, with Valery Spiridonov volunteering as the recipient facing Werdnig-Hoffmann disease.
Contributions of Filipino Innovators
- Fe del Mundo invented the medical incubator, significantly aiding in the care of premature infants.
- Roberto del Rosario developed the patented karaoke machine, affirming his rights in a case against a Chinese company.
- Benjamin D. Cabrera innovated treatments for mosquito-borne diseases and earned accolades for his work on filariasis.
- Benito S. Vergara advanced rice production through research on flowering responses to photoperiodism and improving flood and temperature tolerance.
