To Settle Infinity Question, a New Law of Mathematics | Simons Foundation

To Settle Infinity Question, a New Law of Mathematics | Simons Foundation: "“If forcing axioms are right, then the continuum hypothesis is false,” Koellner said. “And if the inner-model axiom is right, then the continuum hypothesis is true. You go through a whole list of issues in other fields, and the forcing axioms will answer those questions one way, and ultimate L will answer them a different way.”"

Bill Gates: Here's My Plan to Improve Our World — And How You Can Help
http://www.wired.com/business/2013/11/bill-gates-wired-essay/

These days I get to spend a lot of time trying to advance innovation that improves people's lives in the same way that fertilizer did. Let me reiterate this: A full 40 percent of Earth's population is alive today because, in 1909, a German chemist named Fritz Haber figured out how to make synthetic ammonia. Another example: Polio cases are down more than 99 percent in the past 25 years, not because the disease is going away on its own but because Albert Sabin and Jonas Salk invented polio vaccines and the world rolled out a massive effort to deliver them.

APS -66th Annual Meeting of the APS Division of Fluid Dynamics - Event - Urinal Dynamics

http://meetings.aps.org/Meeting/DFD13/Event/202554

In response to harsh and repeated criticisms from our mothers and
several failed relationships with women, we present the splash
dynamics of a simulated human male urine stream impacting rigid and
free surfaces. Our study aims to reduce undesired splashing that may
result from lavatory usage. Experiments are performed at a pressure
and flow rate that would be expected from healthy male
subjects.\footnote{Lapides, J., Fundamentals of Urology, W.B.
Saunders, Philadelphia, 1976.} For a rigid surface, the effects of
stream breakup and surface impact angle on lateral and vertical
droplet ejection distances are measured using high-speed photography
and image processing. For free surface impact, the effects of velocity
and fluid depth on droplet ejection distances are measured. Guided by
our results, techniques for splash reduction are proposed.
