The notion of visibility graphs can be extended to that of pseudo-visibility graphs, where the edges between vertices do not necessarily remain straight line-segments.
This will be a one hour crash course on some of the basic ideas of classical mechanics: configuration space, Lagrangians, the principle of stationary action, and Noether's theorem.
The determinant and the permanent of a matrix, though deceivingly similar in their definitions, behave very differently with respect to how efficiently one can compute these quantities.
If networks of chemical reactions are the circuits of biology then catalysts are the switches. But which species should be called catalysts? Chemistry textbooks answer this question when there is a single reaction.
Climate skeptics today treat climate science and policies derived therefrom as a global conspiracy with the goal of fleecing the non-conspirators, namely the skeptics. The basic objection to the conspiracy is that it is founded on false science.
Euclidean geometry today is most naturally understood as affine geometry equipped with a suitable bilinearity as a basis for notions of length, angle, area, rectangles, circles, etc.
Current emerging applications in the areas of Wireless sensor networks, person-centric remote health monitoring and pervasive computing require sophisticated signal processing algorithms and their corresponding architectural implementation with lo
An elaborate symphony is orchestrated in every living cell. The score is written in DNA, and is played out by RNA and protein enzymes, but where is the conductor of this symphony?
