Intelligent Chaos (IC) is a tool which allows you to study the emergence of chaotic behaviour in the logistic equation and related iterations. There already exist plenty of programs that makes beautiful chaotic graphs, but You will never...

Atom in a Box... [is] a scientific and educational program that aids in visualizing the Hydrogenic atomic orbitals, a prime and otherwise unwieldy example of quantum mechanics. Unlike other tools in this category, this program raytraces through a...

You have the picture of a graph but not the corresponding data? GraphClick is then simply the best way to solve the problem! You just have to click on the graph, and the obtained coordinates of the points can be directly exported to any other...

Regression 2.1 is an easy to use regression analysis program. Data sets can be fitted to linear, logarithmic, exponential, or power equations. Regression 2.1 also computes the relative strength of each fit. Using the model predicted, the check...

Planet Earth is a real-time 3-D model of the Earth with continuously updating night shadows and clouds. It uses an advanced raytracing algorithm and a high resolution satellite image to produce an extremely accurate picture of the Earth. The globe...

Trekkies back off. Nine Worlds hosted by Star Trek: The Next Generation’s, Patrick Stewart, has nothing to do with your campy cult show—there are no sexy aliens in this space story. But, there are a slew of interesting factoids and...

Scientists and engineers employing supercomputers usually see their results as reams of numbers. Well, now these folks have a friend for visualizing their data on the Mac: Spyglass Dicer. Dicer is the third in a set of four packages promised by the...

This is Version 2.0 of MathCAD on two 800k disk images. First and foremost, MathCAD is an equation solver (and isn’t a CAD package). This means that you simply define variables and enter them into an equation, and MathCAD calculates the...

Interactive Physics is more like a tool than a textbook. It’s the spreadsheet program of the Newtonian-mechanics world. With it, you can set up physical situations and see “what if?” scenarios, just as you would with a financial...

When I was a child, one of my prized possessions was a star finder, bought on an excursion to New York’s Hayden Planetarium. At first glance, Voyager might seem like a computerized descendant of those simple cardboard disks, but it’s...

The Dubl-Click Calculator Construction Set makes it easy to design custom calculators that install as desk accessories an your Mac disks. Using MacPaint-like tools, predesigned keys are dragged onto a calculator shell and positioned. The shell can...
