Stumbled upon an interesting site on quantum mechanics. Aimed at engineers, and fine for others with a science background, it explains many of the important ideas of QM, with the math but without getting bogged down in math technicalities. College level. This is not a pop-level work for the common people – it is for those who do have an engineering or science background, comfortable with calculus and scientific reasoning. Reading this won’t get you a physics bachelor’s degree, but for, say, a mechanical engineer or systems engineer who had first year physics and maybe an advanced class or two from the physics department, and now needs to get up to speed on nano or semiconductors or photonics, this site offers a door of understanding into the quantum world.
