HexaChrom turns your iPad into a musical performance controller, enabling you to play your OSC or MIDI (#) electronic musical instruments — virtual instruments running on a laptop/desktop computer, or hardware MIDI instruments. HexaChrom takes an alternative approach to the majority of MIDI keyboard controllers in that it uses an isometric note layout, where the notes are presented as a hexagonal matrix of keys. There are many such isometric layouts, though HexaChrom uses the Harmonic Table layout, which is a modern variati...

Kepler's Orrery is a gravity simulator that composes and plays ambient music. In other words, it's a generative music system that uses gravity equations as its driving force. Kepler's Orrery3 is the new iPad version, with more room for the physics simulation, and the control panels on screen side-by-side with the action. The physics: using basic Newtonian gravity equations and a 1st-order Euler simulation, Kepler's Orrery solves n-body problems in a stepwise fashion. Along the way it plays music while you fiddle with the ...

Caution: This calculator works with RPN entry (like an HP 28, 48, 49, 50g), as well as with algebraic entry. Switch to 'alg' mode to get a "=" key. This calculator does not work like an ordinary calculator, and is not merely an improved version of the Apple calculator. It's designed for calculator enthusiasts, students, professionals. You'd be an unusual kid (in a good sense), if you used it in school. There're 300 pages of documentation on the app's website. You will have to do at least the "Quick Tour" to make good use of it. -...

THE CONCEPT: Define as many banner texts as you like. Besides your own texts iTicker can show - well more or less - useful information like 100 digits of PI, the Morse alphabet, 1 to 10 in 26 different languages or parts of the Human DNA code (one of the most expensive texts in human history by the way). Learn them quite simple - along the way. THE DISPLAY: As display standard fonts and transparent "dot masks" are used. In contrast to LED simulations they offer a lot more facilities. You can choose dots and lines in many different...

AirFlowPad is a virtual 2D wind tunnel. Basically you draw the object, change the wind velocity and follow the calculation live on the screen. After several seconds you see the final pressure and velocity distribution. You can add parts to the object and remove them again to understand the influence of little changes to the air flow. Internally the Euler equation is solved in the Lax-Friedrichs Scheme. For numerical stability this scheme adds an artificial diffusion term, which adds small calculation artefacts. Have fun playing ...

The Missing Calculator is a beautifully simple and powerful calculator designed specifically for the iPad. It’s not too hard to get ahold of a calculator, but finding one that is a pleasure to use can be tricky. The Missing Calculator solves that challenge by bringing you a calculator that is not only functional but matches the modern look and feel of your device. A calculator shouldn’t get in the way. Instead, it should seamlessly complement your work. Every button and feature is thought out and engineered to maximize usability. ...

SophiCalc is an advanced yet easy to use calculator app. General Features: • Perform calculations with arbitrary complex mathematical expressions. • Editing expressions made easy: Position the cursor without restrictions using the build-in magnification glass. • Reuse previously entered expressions via calculation history. • Freely mix the use of arguments in radian or degree for trigonometric or hyperbolic functions in one expression. • Efficient implementation for fast execution and small program size. • Simply touch the result...

Fun and Challenging! Goldbach's Conjecture introduces students to an idea that has baffled mathematicians for centuries. In 1742, a Russian mathematician named Christian Goldbach wrote a letter to Leonhard Euler in which he proposed a conjecture. The conjecture stated that all even numbers greater than two can be expressed as the sum of two primes. This app challenges the player to find two prime numbers to make a target even number. Completing the activity involves using mental math skills. Goldbach Conjecture is designed to be ...

Math Widgets III is the third app in the Math Widgets Series and is a collection of four interactive tools for teaching and learning basic math concepts. The Multibase Abacus Widget helps students understand the meaning of the place value system by challenging them to represent numbers using different number systems. By sliding abacus beads up and down the students represent numbers. The challenge is to show a number equivalent to a given Base 10 number. The Clock Arithmetic Widget displays a clock face and an arrow. The challe...
