Learning by Simulations focuses on math, physics, computer sciences and chemistry. Following is a short overview on the topics covered by the simulation programs. Mathematics Fourier Synthesis, Travelling Salesman Problem, Vector Fields, Sampling Theorem, Splines, AD Conversion, Riemann Sum, Random Number Generators, Tangent and First Derivative, Function Plotter, ... Statistics Central Limit Theorem, Distribution Calculator, Leverage Effect in Regression, Error Surface of Linear Regression, Correlation Coefficient, Regression and Weakly Correlated Data, Time Averaging of Signals, Discrete Distributions, Linear Regression for Chemical Analysis, Measures of Location... Computer Sciences Number systems (binary, octal, decimal, hexadecimal), ASCII Encoding, RGB Color Mixing, Direct Sequence CDMA, ... Physics Electron Multiplier, Radiation of a Blackbody, Varactor Diode, Electric Field Lines, Coupled Radiators, Ion Optics, Gravitational Energy, Optical Lens, Array Antennas, ... Chemistry Mass Spectrometer, Molecular Formulas, Atomic Spectra, Sector Field Mass Spectrometer, Overlapping Chromatographic Peaks, Acid-Base Titration, Calculation of Molecular Weight, Polyprotic Acids, ... We plan to publish, on the average, one interactive learning tool every few weeks, finally arriving at about 100 simulations which will be available for download from this site. So come back in regular intervals and check if there's something new which fits your needs. Recently Published: Polyprotic Acids [Feb-27, 2008] Calculates the distribution of dissociated ions of polyprotic acids. Measures of Location [Oct-04, 2007] Shows the stability of the mean, median, and mode of a distribution. Linear Regression for Chemical Anaylsis [May-30, 2007] Allows to calibrate chemical analysis and to determine the detection limit. Molecular Weight [May-28, 2007] Calculates the chemical molecular weight of a compound. Acid-Base Titration [May-21, 2007] Allows to experiment with acid-base titrations. Array Antennas [Nov-14, 2006] Shows the radiation pattern of array antennas.
