Movement and Exploration Lessons 3-4 Scientists and Mathematicians…. who have inspired, communicated, and transformed their creativity to change our world. Flow Map-Complete the following flow map about scientists Scientists-Lesson 3 How have these creative people moved and explored ideas in science? Johan Gutenberg and Printing Tell how the printing press has changed over the centuries. • 1456 • Created the printing press • Used movable type • 1st printed the Bible Eyeglasses • First eyeglasses in the 1200s • By Mid 1400s the discovery of printing books, etc. increased the demand for the eyeglasses Cause/Effect--Why were eyeglasses created? How do you think this invention lead to other movements in science? How did this affect space exploration? Copernicus • 1543 • Exploration of the Earth’s movement – Earth revolves on own axis – From west to east (24 hours) – Sun, moon, and stars appear to move in the sky Sketches of Aircraft Aero plane Leonardo da Vinci and Aircraft • • • • 1480 Inventor and designer Made sketches of unusual objects Materials not available to bring sketches to life How do these sketches show movement in science? Exploration? Human Body and Science • 1485-1490 • Leonardo da Vinci and Michelangelo studied the human body to better replicate it through their artwork. The Vetruvian Man “ (The Man in Action)" Clocks • 1581 • Pendulum-enabled a better regulator for constant movement of the hands or bell of a clock • Water clocks • Hourglasses Why was this an important inventions? Galileo Galilei Lenses • 1608----Hans Lippershe • Placed lenses together to magnify the image • Used as a military device What exploration was taking place? Spyglass---Telescope • 1609 • Device that made distant objects near • Allowed for many more astronomical discoveries Funny--Humor Microscopes-Biology • Mid-1660s • Many tiny lenses to magnify • Viewed pond water, plant material, even gunk scraped off his teeth How did microscopes allow exploration of our living world? Your Turn • Research one of the following invention. • How did this invention create movement and exploration in science or mathematics? •Map Projection •Watch •Adding Machine •Slide Rule •Air Pump •Reflecting Telescope •Barometer •Pressure cooker •Thermometer •Calculating Machine Circle Map My Invention Research _________ How did this invention show movement and exploration in science and mathematics? Mathematicians- Lesson 4 How have these creative people moved and explored ideas in mathematics? Fibonacci • 1202-Introduced Hindu-Arabic number system into Europe • the positional system we use today - based on ten digits with its decimal point and a symbol for zero • 1 2 3 4 5 6 7 8 9 0 • Order of ordinals matters My exploration of numbers showed patterns in nature. Fibonacci’s Golden Ratio • In mathematics and the arts, two quantities are in the golden ratio if the ratio between the sum of those quantities and the larger one is the same as the ratio between the larger one and the smaller. Fibonnacii Fibonacci’s Golden Ratio Click the link http://www.world-mysteries.com/sci_17_hand.gif Fib Fibonacci in Nature How does this pattern affect the way we look at our natural world? • Sunflowers • Bracts of a pinecone • Petals of a flower http://www.world-mysteries.com/sci_17.htm Why? • It is quite amazing that the Fibonacci number patterns occur so frequently in nature( flowers, shells, plants, leaves, to name a few) that this phenomenon appears to be one of the principal "laws of nature". Fibonacci sequences appear in biological settings, in two consecutive Fibonacci numbers, such as branching in trees, arrangement of leaves on a stem, the fruit lets of a pineapple, the flowering of artichoke, an uncurling fern and the arrangement of a pine cone. The Golden Ratio • ……is a universal law in which is contained the ground-principle of all formative striving for beauty and completeness in the realms of both nature and art, and which permeates, as a paramount spiritual ideal, all structures, forms and proportions, whether cosmic or individual, organic or inorganic, acoustic or optical; which finds its fullest realization, however, in the human form. Fun with Fibonacci • The sequence, in which each number is the sum of the two preceding numbers is known as the Fibonacci series: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181,... (each number is the sum of the previous two). Fibonacci Web-Quest • http://wwwbioc.rice.edu/precollege/galbay/galbay99/t eachers/fibonacci/index.html Blaise Pascal • Age 12 Discovered the sum of the angles of a triangle are two right angles(90+90=180) • 1642--Invented calculator Try This…….. • To build the triangle, start with "1" at the top, then continue placing numbers below it in a triangular pattern. Each number is just the two numbers above it added together (except for the edges, which are all "1").
