Data : Sonification of Science April 21, 2021 By Allison Kubo Hutchison Graphs are the bread and butter of scientists . We love them . Lines plots , bar graphs , line plots . Visual representations of data are the default on science . However , sonification , the transformation of data into sound rather than images has been gaining interest . One reason is that our ears actually have better time resolution than our eyes . This means we can hear more small changes over time than we can see . The eye only perceives a small range of frequencies visible light which ranges between 400-790 THz . However , hearing can pick our sounds

You can picture a muon like a tiny , spinning top they act as if they have an internal magnet , twirling around in response to an applied magnetic field . The strength of a muon's internal magnet is known as the g-factor a dimensionless quantity

Steve Jurvetson Apollo synthetic diamond CC BY 2.0 In late 1940, the Debeers Diamond company started using the slogan Diamonds are forever” to popularize diamond engagement rings . What they didn’t know is that in terms of quantum mechanics that might be true . Diamonds are formed of pure carbon with the atoms arranged tetrahedrally in a strong , rigid crystal structure . They are the hardest known material meaning that they have a hardness of 70-150 GPa in the Vickers Hardness test This
