The Periodic Table: Facts or Committees?  William B. Jensen
I would like to offer two observations relative to the recent letter of Clark and White on the representation of the f-block elements in the periodic table that relate to some disturbing trends in the attitudes of the chemical community towards the nature and use of the periodic table┬Łattitudes that are implicit, though perhaps not intentionally so, in their letter.

Forecasting Periodic Trends: A Semester-Long Team Exercise for Nonscience Majors  John Tierney
Teams of students in a course for nonscience majors identify trends among the properties of elements in the periodic table, use Excel to plot and produce best-fit equations to describe relationships among those properties, and apply the resulting formulas to predict and justify the properties of missing elements.

News from the Periodic Table: An Introduction to "Periodicity Symbols, Tables, and Models for Higher-Order Valency and Donor–Acceptor Kinships"  Henry A. Bent and Frank Weinhold
Proposes that alternative display topologies such as a 2D "left-step" or "step-pyramid" table or 3D "periodic towers" can supplement or supplant the standard periodic table by better emphasizing higher-order patterns of chemical association and reactivity, rather than the physical resemblances of standard-state elemental substances.
