Real Science Su Song Chinese mechanical and horological engineering from the Song Dynasty; this diagram provides an overall general view of the inner workings and armillary sphere of Su Song's clocktower built in Kaifeng. The drawn illustration comes from Su Song's book Xin Yi Xiang Fa Yao published in the year 1092. On the right is the upper reservoir tank with the 'constant-level tank' beneath it. In the center foreground is the 'earth horizon' box in which the celestial globe was mounted. Below that are the time keeping shaft and wheels supported by a mortar-shaped end-bearing. Behind this is the main driving wheel with its spokes and scoops. Above that are the left and right upper locks with an upper balancing lever and upper link. Real Science Zhang Heng (張衡) applied his extensive knowledge of mechanics and gears in several of his inventions. He invented the world's first water-powered armillary sphere, to represent astronomical observation; improved the inflow water clock by adding another tank; and invented the world's first seismometer, which discerned the cardinal direction of an earthquake 500 km (310 mi) away. Zhang Heng Seismometers Su Song a statesman astronomer cartographer horologist pharmacologist mineralogist zoologist botanist mechanical architectural engineer poet antiquarian ambassador 1 Corinthians 15:49 "And as we have borne the image of the earthy, we shall also bear the image of the heavenly." For centuries the Chinese were the world's greatest scientists and engineers. Many people know that the Chinese invented the compass and gunpowder, but these are only the beginning. Over 1,000 years ago, Chinese astronomer Su Song built the first planetarium. He even tilted it at a precise 23.5 to match the Earth's tilt. More than 2,000 years ago another Chinese astronomer noted the moons of Jupiter -- long before Galileo "discovered" them. Almost 1,000 years ago, the Chinese used gunpowder to make over 30 types of fire arrows, including one that was a two-stage rocket. They were great shipbuilders as well. One of the most famous examples is a nine-masted, 300-foot ship with watertight bulkheads. The Chinese-invented odometer featured reduction gears and carved figures that beat a drum every time a distance of about one-fifth of a mile was traveled. The world's first known working seismometer -- a device that registers earthquakes -- was built in 132 AD. A 16th-century palace roof was designed with a series of interlocking joints that were layered to provide flexibility in case of an earthquake. As our knowledge of humanity reaches into history and grows, the picture we are seeing is not that of a primitive becoming more like a modern human. Rather, we see humans -- ever curious and inventive -- creatures that are very different from the animal world. Truly we have come from the hand of God Himself! Prayer: Lord, I have yet to begin realizing the wonderful abilities You have given me. For this forgive me. Teach me not to seek for myself what You already provide, but rather to develop those things within myself that You have given me to develop in service to You. Amen.
