Computational thinking in science

Computers can be used to help solve problems. However, before a problem can be tackled, the problem itself - and the ways in which it could be solved - needs to be understood. Computational thinking helps with this. It allows us to take a complex problem, understand what the problem is and develop possible solutions. These solutions can then be presented in a way that a computer, a human, or both, can understand. Three important elements of computational thinking are:.

A complex problem is one that, at first glance, does not have an obvious, immediate solution. Computational thinking involves taking that complex problem and breaking it down into a series of small, more manageable problems. Each of these smaller problems can then be looked at individually. Next, simple steps to solve each of the smaller problems can be designed. Finally, these simple steps are used to program a computer to help solve the complex problem in the best way.

Thinking computationally is not programming. It is not even thinking like a computer, as computers do not, and cannot, think. Simply put, programming tells a computer what to do and how to do it. Computational thinking enables you to work out exactly what to tell the computer to do.

For example, if you agree to meet your friends somewhere you have never been before, you would probably plan your route before you step out of your house. You would then follow the step-by-step directions to get there. In this case, the planning part is like computational thinking, and following the directions is like programming. Being able to turn a complex problem into one that can be easily understood is a skill that is extremely useful. Computational thinking Computers can be used to help solve problems.

Computational thinking allows us to take a complex problem, understand what the problem is and develop possible solutions. We can then present these solutions in a way that a computer, a human, or both, can understand. There are four key techniques cornerstones to computational thinking:. Each cornerstone is as important as the others.

They are like legs on a table - if one leg is missing, the table will probably collapse. Correctly applying all four techniques will help when programming a computer. A complex problem is one that, at first glance, we don't know how to solve easily. Computational thinking involves taking that complex problem and breaking it down into a series of small, more manageable problems decomposition. Each of these smaller problems can then be looked at individually, considering how similar problems have been solved previously pattern recognition and focusing only on the important details, while ignoring irrelevant information abstraction.

Next, simple steps or rules to solve each of the smaller problems can be designed algorithms. Finally, these simple steps or rules are used to program a computer to help solve the complex problem in the best way. What is computational thinking? The four cornerstones of computational thinking There are four key techniques cornerstones to computational thinking: decomposition - breaking down a complex problem or system into smaller, more manageable parts pattern recognition — looking for similarities among and within problems abstraction — focusing on the important information only, ignoring irrelevant detail algorithms - developing a step-by-step solution to the problem, or the rules to follow to solve the problem Each cornerstone is as important as the others.

Computational thinking in practice A complex problem is one that, at first glance, we don't know how to solve easily.The computer revolution has profoundly affected how we think about science, experimentation, and research. DOI: A quiet but profound revolution has been taking place throughout science. The computing revolution has transformed science by enabling all sorts of new discoveries through information technology.

Throughout most of the history of science and technology, there have been two types of characters. One is the experimenter, who gathers data to reveal when a hypothesis works and when it does not. The other is the theoretician, who designs mathematical models to explain what is already known and uses the models to make predictions about what is not known.

The two types interact with one another because hypotheses may come from models, and what is known comes from previous models and data. The experimenter and the theoretician were active in the sciences well before computers came on the scene.

When governments began to commission projects to build electronic computers in the s, scientists began discussing how they would use these machines. Nearly everybody had something to gain.

Unit 1: Computational Thinking

Experimenters looked to computers for data analysis—sifting through large data sets for statistical patterns. Theoreticians looked to them for calculating the equations of mathematical models. Many such models were formulated as differential equations, which considered changes in functions over infinitesimal intervals. Consider for example the generic function f over time abbreviated f t. Suppose that the differences in f t over time give another equation, abbreviated g t.

This calculation could easily be extended to multiple space dimensions with difference equations that combine values on neighboring nodes of a grid.

In his collected works, John von Neumann, the polymath who helped design the first stored program computers, described algorithms for solving systems of differential equations on discrete grids.

Numerical results from calculation described in caption of previous image are converted to colored images that reveal where the stresses on the aircraft are greatest. Using the computer to accelerate the traditional work of experimenters and theoreticians was a revolution of its own. But something more happened.

Computational thinking

Scientists who used computers found themselves routinely designing new ways to advance science. Simulation is a prime example. By simulating airflows around a wing with a type of equation called Navier-Stokes that is broken out over a grid surrounding a simulated aircraft, aeronautical engineers largely eliminated the need for wind tunnels and test flights. Astronomers similarly simulated the collisions of galaxies, and chemists simulated the deterioration of space probe heat shields on entering an atmosphere.

Simulation allowed scientists to reach where theory and experiment could not. It became a new way of doing science. Scientists became computational designers as well as experimenters and theoreticians. They became computational designers as well as experimenters and theoreticians. Another important example of how computers have changed how science is done has been the new paradigm of treating a physical process as an information process, which allows more to be learned about the physical process by studying the information process.

Biologists have made significant advances with this technique, notably with sequencing and editing genes. Data analysts also have found that deep learning models enable them to make surprisingly accurate predictions of processes in many fields. For the quantities predicted, the real process behaves as an information process. The two approaches are often combined, such as when the information process provides a simulation for the physical process it models.

The term computational science, and its associated term computational thinking, came into wide use during the s. Intheoretical physicist Kenneth Wilson received a Nobel Prize in physics for developing computational models that produced startling new discoveries about phase changes in materials.Computational Thinking is a problem solving method that uses computer science techniques.

The term computational thinking was first used by Seymour Papert in Computational thinking can be used to algorithmically solve complicated problems of scale, and is often used to realize large improvements in efficiency.
