STS

• Every decade, or perhaps every year, brings with it some epic geniuses and their ground-breaking inventions in various fields
• There are inventions that, once invented, they consume us, alter the way the human species live and make the world smarter, better and sometimes even more fun
• Steam Engine


  Combustion of a fuel releases a high-temperature gas and as it expands it applies pressure to a piston and moves it
• The steam engine played a pivotal role in invention of other machinery such as automobiles and airplanes that changed the face of the planet we live in
• Wheel


  A symmetrical component moving in circular motion on an axis
• The wheel has been used to facilitate farming and transportation and discover other great inventions from clocks to vehicles
• Printing Press


  Allowed documents, books and newspapers to be disseminated to a much wider audience in Europe
• The cultural and industrial revolution in Europe would not have been possible if it wasn't for the rapidity with which printing press allowed documents, books and newspapers to be disseminated
• Computer


  Has helped high performance military aircrafts to fly, put a spaceship into orbit, control medical equipment, create visual imagery, store vast amounts of information and allowed the functioning of car, phones and power plants
• Internet


  First developed in 1973 by Vinton Cerf backed by the US Department of Defense Advanced Research Projects Agency (ARPA)
• In 1996, more than 25 million computers were connected through the internet across 180 countries
• World Wide Web


  Invented in 1989 by a CERN employee, Tom Berners Lee. Has transformed the way we work in various field including education, music, finance, reading, medicine, dating, networking, language and the like
• Television


  Invention of the modern television was the work of Vladimir Kosma Zworykin (1923) and Philo Farnsworth (1927)
• People typically spend around 4-8 hours watching TV per day and it has drastically impacted family and social life
• Light Bulb


  Invented by Thomas Alva Edison in 1879, revolutionized indoor living
• Penicillin


  Accidently discovered in 1928 by Nobel Prize winner, Alexander Fleming, cures several infections in human beings without harming them
• Telephone


  Invented by Alexander Graham Bell in 1876, has had life-saving impact on mankind especially in the field of business and communication
• Florescent light tube invented by Agapito Flores is one of the most commonly used lighting device in the world
• Fe del Mundo invented the incubator and jaundice relieving device
• Roberto del Rosario invented the Karaoke Sing Along System in 1975
• Edwardo San Juan invented the Moon Buggy or the Lunar Rover used by Neil Armstrong and other astronauts when they first explored the moon in 1969
• Gregorio Zara invented the videophone in 1955
• Abelardo Aguilar discovered the antibiotic erythromycin in 1949
• Rudy Lantano Sr. invented Alco-Diesel, Lan-Gas and Superbunker Formula L in 1996
• Dr. Virgilio "Billy" Malang invented the Feminine Hygiene or The External Vaginal Cleanser
• Diosdado Banatao introduced the first single-chip graphical user interface accelerator, pioneered the local bus concept for personal computers, and developed the First Windows accelerator chip
• Francisco Quisumbing invented the Quink ink for Parker Pens
• Aristotle


  Ancient Greek philosopher and scientist
• Aristotle's model of the Universe had a series of 53 concentric, crystalline, transparent spheres rotating on different axes, with a stationary Earth at the center
• Ptolemaic model


  Earth-centered, or geocentric model of the universe
• Ptolemaic model


  1. Each planet moved on a small sphere or circle (epicycle) that moved on a larger sphere or circle (deferent)

  2. Stars moved on a celestial sphere around the outside of the planetary spheres
• Ptolemy thought all celestial objects, including planets, Sun, Moon, and stars, orbited Earth, which did not move
• Copernican Revolution


  Sun-centered, or heliocentric model of the universe
• Nicolaus Copernicus was a Polish astronomer who synthesized observational data to formulate a Sun-centered cosmology, launching modern astronomy and setting off a scientific revolution
• Copernicus had two main reasons for asserting the Sun was the center of our solar system: the Ptolemaic model was not precise, and it had big epicycles to explain the retrograde motions of the planets
• Copernicus was correct that the planets orbit the Sun, but wrong that the Sun is the center of the universe and that the orbits are circular
• Tycho Brahe


  Danish astronomer who built an observatory to measure the position of planets with high accuracy, and noted previous measurements were incorrect
• Brahe proposed a model of the solar system with all the planets (except Earth) orbiting around the Sun, but the Sun orbiting around the Earth
• Johannes Kepler


  German astronomer who, using Tycho Brahe's precise data, recognized that the orbits of the planets are ellipses, not circles
• Kepler's Three Laws


  • The orbits of the planets are ellipses, with the Sun at one focus
  • The line joining the planet to the Sun sweeps out equal areas in equal intervals
  • The squares of the sidereal periods are proportional to the cubes of the semi-major axes
