Generally the heavier an element the easier it is to split its atom (fission). The mass of the fragments is less than that of the original atom and the lost mass is converted into energy (E=mc^2). The fission also releases more slow neutrons which go on to provide the chain reaction.
GoPro to start manufacturing in Brazil. Local production of the action cameras could lower prices by up to 30 percent. Wearable video camera maker GoPro will start manufacturing its products in Brazil to lower prices and widen its local footprint. Raspberry Pi add-ons: My experiments with camera and wi-fi.
The camera is waterproof up to 10 m, supports 4k HEVC video recording at up to 60 fps and 1080p at up to 240 fps, automatic upload of footage to cloud, voice controls and 5 Ghz Wi-Fi. It will be the first GoPro with its own custom system on a chip (SoC) the GP1.
