Vor 3 Tagen · In quantum mechanics, an atomic orbital ( / ˈɔːrbɪtəl /) is a function describing the location and wave-like behavior of an electron in an atom. [1] . This function describes the electron's charge distribution around the atom's nucleus, and can be used to calculate the probability of finding an electron in a specific region around the nucleus. [2]
Vor 3 Tagen · Over on his YouTube channel, Rob VK8FOES has started a new video series about Iridium Satellite Decoding. Iridium is a constellation of low-earth orbiting satellites that provide voice and data services. Iridium was first decoded with low cost hardware by security researchers back in 2016 as mentioned in this previous post. Being unencrypted it is possible to intercept private text and voice ...
