It was believed that this was a 'strange' method of decay, which is why the scientists gave the particles that name. This means that any particle that contains a strange quark can not decay due to strong force (or electromagnetism), but instead with the much slower weak force. Python releases by version number: Release version Release date Click for more. What makes strange quarks different from down quarks–apart from having 25 times the mass of down quarks–is that they have something that scientists call "strangeness." Strangeness is basically a resistance to decay against strong force and electromagnetism. Like all fermions (which are particles that can not exist in the same place at the same time), strange quarks have a spin of 1/2. If you dont know which installation method you need or prefer, we recommend the Scientific Python Distribution Anaconda. Like down quarks, strange quarks have a charge of -1/3. Strange quarks are the third lightest quarks, which are subatomic particles that are so small, they are believed to be the fundamental particles, and not further divisible.
