Superiority Discounting Implies the Preposterous Conclusion

Positive Temporal Dependence of the Biological Clock Implies Hyperbolic Discounting

Temporal preferences of animals and humans often exhibit inconsistencies, whereby an earlier, smaller reward may be preferred when it occurs immediately but not when it is delayed. Such choices reflect hyperbolic discounting of future rewards, rather than the exponential discounting required for temporal consistency. Simultaneously, however, evidence has emerged that suggests that animals and h...

Polynomial algorithms that prove an NP-Hard hypothesis implies an NP-hard conclusion

A number of results in hamiltonian graph theory are of the form P1 implies P2, where P1 is a property of graphs that is NP-hard and P2 is a cycle structure property of graphs that is also NP-hard. Such a theorem is the well-known Chvátal-Erdös Theorem, which states that every graph G with α ≤ κ is hamiltonian. Here κ is the vertex connectivity of G and α is the cardinality of a largest set of i...

Dark Energy and the Preposterous Universe

A brief review is offered of the theoretical background concerning dark energy: what is required by observations, what sort of models are being considered, and how they fit into particle physics and gravitation. Contribution to the SNAP (SuperNova Acceleration Probe) Yellow Book.
