simulate

service lets city managers and event planners run simulations of things like traffic, public transport, or supply chain infrastructure for entire cities or countries, according to AWS. City planners, for example, could run simulations for natural disasters that might occur in order to test response systems. Event planners could similar a large sporting event to see how it would impact nearby traffic conditions.The compute problem AWS claims to solve is that spatial simulations have been generally confined to running…

Global sea level changes in recent decades. Coastal cities with rising sea levels will be more vulnerable to ongoing global climate change. Credit: Hongyin Chen According to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change, the global mean sea level has risen faster since 1900 than over any preceding century in the last 3000 years. This makes hundreds of coastal cities and millions of people…

Credit: CC0 Public Domain Climate models are powerful tools that scientists use to study how the climate system works now and how it will change in the future under different scenarios of global warming. When models are updated with new scientific information, they must be evaluated to see how well they represent different climate features, including weather patterns found in particular geographical regions.…

As astronomers search for life outside our solar system, they have to try and answer one big question: What’s the recipe for a habitable planet? We tend to think about the ingredients we encounter every day: liquid water, the protective blanket of the atmosphere, a sun that is neither too warm nor too hot. But there are other factors that are probably equally important: Earth’s cooled and hardened crust, its gooey molten guts, its magnetic field, its volcanoes and deep sea vents. These are the features that fostered…

The four-wheeled, two-armed Interact rover spent four days collecting rocks on Mount Etna. Photo: ESAWhile working out of a hotel room in Italy, astronaut Thomas Reiter commanded a four-wheeled robot to pick up rocks from the surface of an active volcano on the Sicilian east coast, and he did so while role-playing as though he were in orbit around the Moon. The four-day simulation is part of the European Space Agency’s (ESA) preparation for a future mission to the Moon, where it plans to land a rover on the lunar surface…

Simulate a tiny solar system with Sun, Earth, Mars, and an unknown comet using real mass, distance, and velocity data in MatplotlibA solar system with the sun, earth, mars, and comet. GIF by Andrew ZhuI was amazed by the PCA (Principal Components Analysis) and thinking of using animation to show the machine learning processes. When I managed to animate a graph, I was tempted to animate something cool. The first cool stuff that comes to me is the solar system. This article is also a journey of me recalling the knowledge of…

Fast radio bursts are one of the biggest cosmic mysteries of our time. They're extremely powerful but extremely brief explosions of electromagnetic radiation in radio wavelengths, discharging in milliseconds as much energy as 500 million Suns.  For years, scientists puzzled over what could be causing these brief outbursts, detected in galaxies millions to billions of light-years away. Then, in April 2020, we got a really strong lead: a brief, powerful flash of radio waves from something inside the Milky Way – a…

A hundred kilometers away from the city of La Rioja, Argentina — and a thousand away from the capital Buenos Aires — lies the Los Colorados provincial reserve, which holds a Martian landscape filled with red soil and orange canyons. In this area, the Solar54 project will carry out a series of studies and tests of the different variables that will determine the human colonization of Mars. It seeks to recreate the environment of Mars so that space agencies from all around the globe can run tests…
