To better understand the value of big data, think of it in terms of three v's: variety, velocity and volume. The data pools swell and spread, overlapping and merging until there are no more pools - just the vast sea of information we call big data. ![]() ![]() In fact, according to IBM, 90 percent of the data in the world today was created in the last two years alone. The information about the world pours in at an exponential rate. (To give you an idea of how crazy that number is, some people have conservatively estimated that all the words ever spoken by humans equal 5 quintillion bytes of data.)Īll that new data comes from climate sensors, social media hubs, digital media Web sites, online transaction records, cell phone GPS signals and countless other sources. The science of weather prediction is far from perfect, but better equations, more powerful computers and a widening array of atmospheric data sets continue to improve the accuracy of our simulations.īut can we really simulate the world itself? To find out, we have to travel the waters of big data.īut the rain continues to fall and the puddles of data continue to swell, to the tune of 2.5 quintillion bytes per day. Computer advancements allowed meteorologists to move beyond mere observation-based predictions and implement numerical weather prediction (NWP) models, in which computers pull past and present atmospheric data to construct predictive models of future weather. Just consider meteorology, the scientific study of atmosphere and weather. Built in 1949 by engineer and economist Bill Phillips, the MONIAC used the flow of colored water through pipes, drains and pumps to simulate the British economy.ĭigital computing, however, changed everything. The Monetary National Income Analogue Computer (MONIAC) stands as another classic example of analogue computing. The astrolabe was essentially an analogue computer, a pre-digital device that incroporated electrical, hydraulic or mechanical systems to simulate another system. The user plotted colossal, interstellar movements while holding the device in the palm of his or her hand and manipulated the data to gauge time, location and distances. The ancient astrolabe, for instance, served as an indispensable astronomical tool for more than 2,000 years and is a working model of the night sky and the position of the stars. As a team, we will be able to help students succeed in the classroom and the world outside, by better understanding each other's needs and expectations.Humans also developed the means to copy more than mere physical forms. Within science, the relationship between the science teacher, parents, and students can be best described as a team. Finally, 8th grade is Physical Science: chemistry and physics. In 7th grade, the students learn about Life Science: cells, classification of life, genetics, evolution, and ecology. The 6th-grade curriculum focuses on Earth Science: basic chemistry, water systems, atmosphere & weather, energy, and space. Our teachers bring science to life through investigations and activities. Critical thinking, problem solving, and analytical skills are stressed in all 3 grade levels. Our goal is to provide students with the knowledge and skills necessary to navigate the 21st century. ![]() Science at Shirley Heim is an exploration of our world and the interactions between the living and nonliving components.
