RadioWORKS is a tool for calculating various items related to radio waves. It enables you to calculate the wavelength and proper antenna length for any given frequency, and also includes an "Inverse Square Ratio" calculator. RadioWORKS is FREEWARE.

Nim logic game. It is a 2-player game, but you can play against the computer. The rule of the game is to take one or more pieces from one row on the board. Then, the other player goes, etc. The winner is the player that takes the last p

You can see invisible electric field - if you use "Electric Field". It is an excellent tool forvisualizing electric field and equipotential lines. Visibility of field line and potential surface depends on their magnitude.

This tool will show the proportions between nucleotides in a DNA sequence. You don't need to install it or unpack it. Just download the program and double click to run it. Other software: DNA Baser is an affordable alternative for assembly of DNA sequences and generation of contigs. File formats supported are abi, scf and seq (or FASTA). Chromatograms of the assembled sequences are displayed in a synchronized format with the generated contig.

All-in-one freeware for pH and equilibrium calculations, real data analysis and simulation of titration curves of acids, bases, salts and buffers (from simple solutions to complex mixtures) with interpolation, smoothing and nonlinear regression.
