Following the first part of this article series, I will examine the notion of φ-sciences' φ-ness on the example of Vihalemm's early chemical studies on affinity and both early and later accounts of the periodic table. I analyse these cases as instances where he applies the term...
FEMALE STUDENT: Yes, um, Professor Harrison? You were saying that the periodic table is predictive?What exactly does that mean?I mean, I understand how it organizes the elements, but … where’s the prediction? MALE PROFESSOR: OK, let's look at our periodic table again.OK - it groups ...

Learning about these things helps us better understand the world we live in.But have you ever noticed something missing in the periodic table? There were already 114 elements. But the seventh row of the table was not f___, until now! In December, scientists from IUPAC(国际理论与应用化学联...
possible to aggregate these totals for products and territories, it does not make sense to add them together for the dimDate dimension. For instance, if there were 25 widgets in stock on July 27, and 25 widgets on July 28, it does not mean that there are a total of 50 widgets in ...

this would be a whole number, adding the number of protons, neutrons, and electrons together for the atom. However, the value given in the periodic table is an average of the mass of allisotopesof a given element. While the number of ...
