![]() We’ve spoken about earthquakes before, and this domain continues to see new developments. We also have information about atmospheric conditions, including wind chill, humidity, location-specific heating and cooling days, and the heat index. We’ve also been able to add quite a bit of information about astronomical events, such as meteor showers, and their properties.įor those concerned with issues closer to home, we’ve added information about clouds and the composition of our atmosphere. We had a massive amount of astronomical data when we first launched Wolfram|Alpha, but over the summer and fall we added a great number of solar system features, including maps of planets, data about craters of planets and moons, and detailed information about Jupiter’s Great Red Spot. We’ve added carbon footprint data, providing information about the carbon footprint of various activities such as heating our homes or taking a road trip. To complement the information we have been providing about the human genome, we now have the genomic structure of the mouse, including information about DNA sequences relative to specific genes. Our physical exercise calculator may be one of Wolfram|Alpha’s most useful new additions, allowing users to compute energy expenditure, fat loss, and oxygen consumption for dozens of different activities, from running to rowing. We now support all of the most commonly used periodic tilings, such as basketweave and zigzag tiling. More tiling support has been added to our geometry offerings. Some highlights include better plotting, more derivatives and integrals, more step-by-step results, better linguistics for inputting your computations, and complex analysis features such as computing the residue. You can also now explore all the famous categories of fractals.Īnother major area of improvement is in algebra, including better support for sums and matrix computations.įor calculus and analysis you will find more advanced support throughout Wolfram|Alpha. You have more ways to explore cellular automata as well as support for string substitution systems. Our support of computational sciences has expanded. ![]() You can also explore traditional areas of combinatorics such as coin flips and card playing. You can now compute any probability for any distribution that is known by Mathematica, or find the set on which the density of the statistical distribution is non-zero. Improvements to our capabilities in probability and statistics have also been made. Users will find many updates in discrete mathematics for areas like combinatorics and graph theory. Users will also find improved plotting for special functions. ![]() As we near the end of 2009, we wanted to look back at seven months of new Wolfram|Alpha features and functionality.Īn impressive collection of advanced support for mathematical functions has been added, including more support for Bessel functions, gamma functions, elliptic functions, and zeta functions. We’ve highlighted some of these new additions in this blog, but many more have entered the system with little fanfare. Since then, we’ve successfully released a new build of Wolfram|Alpha’s codebase each week, incorporating not only hundreds of minor behind-the-scenes enhancements and bug fixes, but also a steady stream of major new features and datasets. When we launched Wolfram|Alpha in May 2009, it already contained trillions of pieces of information-the result of nearly five years of sustained data-gathering, on top of more than two decades of formula and algorithm development in Mathematica.
