How to Detect that a Problem is Not Bounded with the Simplex Method
Energy & ResourcesThe Simplex Method is an algorithm that allows us to solve Linear Programming models that in certain occasions allows us to identify exceptional cases such as infinite optimal solutions or that the problem is not bounded. In this context the Simplex Method rescues the conditions established in the Fundamental Theorem of Linear Programming. In the

What are we seeing when we see the curvature of Earth?
Energy & ResourcesAsked by: Michael Hoff It is possible to see the effect of the curvature of the earth from sea level (ships disappearing over the horizon). To actually see the curvature directly (ie to be able to see the horizon as an arc, rather than a straight line) requires an altitude of over 50,000 feet. How

Is there open scientific analysis of the proposed discharge of water from Fukushima?
Energy & ResourcesAsked by: Debbie Contreras Is Fukushima still leaking radioactive water? Radioactive waste water has been discharged into the Pacific Ocean since the Fukushima Daiichi nuclear disaster, triggered by the 2011 Tōhoku earthquake and tsunami on in Japan. How much radioactive water was released from Fukushima? 1.25 million tons Japan announced today it will release 1.25
