Can we compare apples and oranges? We certainly can…when we use statistics! In the activity Comparing Two Numerical Distributions, students compare two populations by looking at the similarities and/or differences between them. The populations in this activity are drawn from familiar real world scenarios to which students can relate. This way, the comparisons and interpretations […]

Come scrivono i Rudi Mathematici, "John Forbes Nash se n'è andato". C'è poco da dire in situazioni del genere, se non provare a scrivere, magari della sua matematica. Ho provato a farlo in modi piuttosto indiretti, lo faccio oggi in un modo un po' più diretto.Uno dei risultati più importanti di John Nash è la scoperta dell'esistenza degli equilibri che portano il suo nome all'interno dei giochi non collaborativi. La teoria di base su questo genere di giochi prende le mosse da due suoi […]

http://t.co/gCOlKccELA about #IngeLehmann #EarthCore #theCore #geophysics Inge Lehmann was a Danish seismologist and geophysicist. Using seismic data, she discovered the inner solid core of the Earth with some physical properties distinct from the outer liquid core: No rays emerged at epicentral distances between 112° and 154°. I then placed a smaller core inside the first core and let the velocity in it be larger so that a reflection would occur when the rays through the larger core met it.
