A computer simulation, a computer model, or a computational model is a computer program, run on a single computer, or a network of computers, that attempts to simulate an abstract model of a particular system. Computer simulations have become a useful part of mathematical modeling of many natural systems in physics (computational physics), astrophysics, chemistry and biology, human systems in economics, psychology, social science, and engineering. Simulation of a system is represented as the running of the system's model. It can be used to explore and gain new insights into new technology, and to estimate the performance of systems too complex for analytical solutions.
There’s a lot of fuss about climate modeling is definitely a hot one, with the validity of certain models (and models in general) often being brought to question. So how could you test if the today’s models are correct, except for waiting? That’s still a debatable question, but if we were to look at past [...]
There’s a rather common image that might pop inside someone’s head when thinking of penguins – an entire flock of such animals, standing very close together, keeping themselves warm as they confront extreme sub-zero antarctic temperatures. Don’t be fooled, though. According to the results of a mathematical simulation that modeled penguin huddling, the penguins stick [...]
Pack your bags and save the children ladies and gents, it’s the end of the world! A group of researchers suggests that the odds are wild Arabica coffee will go extinct well by the end of the century, dealing a devastating blow to the coffee industry. The study was conducted by researchers from the Royal [...]
The plot of the Hollywood blockbuster flick Armageddon is fairly simple – a giant asteroid is hurling towards Earth, threatening to obliterate all life on the planet as we know it. A team of brave oil-drillers is sent on the space rock to diffuse the threat by detonating a nuclear warhead placed inside the asteroid itself. Apparently, a group [...]
Since 1995, over 500 planets that don’t orbit our Sun have been discovered, with the numbers increasing more and more in the past years. But only recently did astrophysicists observe that in some of these cases, the star seems to be spinning in one direction, and the planet orbits it in the totally opposite direction [...]
