Thoughtful authors for inquiring readers: activism, catastrophe, insurgency, and the ephemera of life on this lucky planet

The new book shelf is brimming with books full of big ideas to challenge your thinking.  Here are just a few titles to get you started:

• The David Suzuki reader : a lifetime of ideas from a leading activist and thinker 
• Climate insurgency : a strategy for survival / Jeremy Brecher.
• Field notes from a catastrophe : man, nature, and climate change / Elizabeth Kolbert.
• Eternal ephemera : adaptation and the origin of species, from the nineteenth century through punctuated equilibria and beyond / Niles Eldgredge
• Lucky planet : why Earth is exceptional-- and what that means for life in the universe / David Waltham.

So many wonderful books awaiting your discerning and thoughtful response!  Living on this lucky planet calls us to pay attention to what is important and what needs to be done to sustain life and a healthy, holistic environment.  These authors can help along the way.

Publication on Kerr black hole momentum by Assistant Professor of Physics Robert Owen

Recently published:  Lovelace, G; Scheel, MA; Owen, Robert, Physics & Astronomy Dept; Giesler, M; et al. 2015.

Nearly extremal apparent horizons in simulations of merging black holes.
Classical and Quantum Gravity 32(6):065007  [A journal from Institute of Physics @ IoPScience]

Partial abstract:
The spin angular momentum S of an isolated Kerr black hole is bounded by the surface area A of its apparent horizon: 8 pi S A. We show that the overspun surfaces are indeed superextremal: our lower bound on their Booth-Fairhurst extremality exceeds unity. However, we confirm that these superextremal surfaces are always surrounded by marginally outer trapped surfaces (i.e., by apparent horizons) with 8 pi S < A. The extremality lower bound on the enclosing apparent horizon is always less than unity but can exceed the value for an extremal Kerr black hole.
