Atom in a Box vs steps2MATH

Atom in a Box is an aid for visualizing the Hydrogenic atomic orbitals, the three-dimensional states that the electron occupies in Hydrogen, a prime and otherwise unwieldy example of Quantum Mechanics. It interactively shows what the Hydrogen atom "looks" like. Unique among visualizations of Quantum Mechanics, it uses highly optimized code to perform 3D volumetric raytracing through the electron wavefunction's probability density and presents its results in real-time. It animates and mathematically describes all 140 eigenstates up to the n=7 energy level. The app links to an online FAQ, and the atom rotates with multitouch and the accelerometer. The bottom line is: Explore! The user are meant to explore all aspects of the atom, what it is and what it can do.

Say goodbye to “math is stupid” and welcome to steps2Math. True to the motto “Understand instead of despair,” steps2Math provides students, parents, and teachers in grades 5 through 11 with an accessible way to approach mathematics. That’s because steps2Math doesn’t just calculate and solve math problems—it shows the corresponding solution steps one by one. Features of steps2Math: • Algebra problems can be entered. • The solution process is generated and displayed. • Each step in the solution is accompanied by an explanation. • The steps are highlighted in red and linked to the explanations. • Side calculations (addition, division, multiplication) • For functions, the corresponding graphs are generated. • Graphs for both sides of an equation. • For functions, a value table is also displayed alongside the graph. • The graphs can be zoomed in, zoomed out, and moved as desired. • For equations, the verification step is also performed. • 35 languages are supported. • You can switch between them at any time within the app. • Local number formatting is supported for some languages. • The output can be customized to the user’s preferences and abilities. • An extensive collection of exercises with more than 500 templates. • The practice problems are generated anew from templates each time. • As a result, Steps2MATH contains countless exercises. • Calculations are performed with precision. • Rounded values are also displayed. • The exercises can be saved as documents. • History • Conversion of units of measurement • SI units from ampere to weber. • Other units such as inches and yards. The app can also be used as a scientific calculator. Mathematical features: • Natural numbers • Integers • Fractions • Decimals • Rational numbers • Percentages • Powers • Algebraic manipulations • Linear equations • Systems of linear equations • Roots • Quadratic equations • Trigonometric functions (π/°) • Exponential functions • Logarithms • Complex numbers • Signum • Rounding • Absolute value • Binomial coefficients • Differential calculus
