To count the number of cells in the human body, Ian Hatton at the Max Planck Institute for Mathematics in the Sciences in Leipzig, Germany and his colleagues analysed over 1500 scientific papers, looking at factors such how many cell types are there in the body, how many of each type ar...
(EOS). An EOS occurs every time the LED driving current or voltage exceeds the component maximum rated values. There are many different types of EOS - some are generated during the LED assembling or testing process, while others are produced by the power supply or come from...
"Phantom energy," also known as "standby energy" or "vampire energy," is the electricity used by electronics when turned off or in standby mode. According to the U.S. Department of Energy (DOE), standby energy accounts for 5% to 10% of residential energy use—which can add up. Smart...
