http://feeds.sciencedaily.com/~r/sciencedaily/computers_math/mathematics/~3/1HdvciZVGYQ/170809073629.htm
Students from families with little interest in math benefit more from a school intervention program that aims at increasing math motivation than do students whose parents regard math as important. A study indicates the intervention program has a "Robin Hood effect" which reduces the "motivational gap" between students from different family backgrounds because new information about the importance of math is made accessible to underprivileged students.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/1HdvciZVGYQ" height="1" width="1" alt=""/>Wed, 09 Aug 2017 07:36:29 EDThttps://www.sciencedaily.com/releases/2017/08/170809073629.htmhttps://www.sciencedaily.com/releases/2017/08/170809073629.htmNew model for bimolecular reactions in nanoreactors
http://feeds.sciencedaily.com/~r/sciencedaily/computers_math/mathematics/~3/R70KT9qfuRU/170804091344.htm
Theoretical physicists have devised a mathematical model of two different molecules reacting within so called nanoreactors that act as catalysts. They gained surprising new insights as to what factors promote reactions and how to control and select them. The model is relevant for a wide range of research fields, from biophysics to energy materials.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/R70KT9qfuRU" height="1" width="1" alt=""/>Fri, 04 Aug 2017 09:13:44 EDThttps://www.sciencedaily.com/releases/2017/08/170804091344.htmhttps://www.sciencedaily.com/releases/2017/08/170804091344.htmOnline assessment could improve math marks of deaf learners

A new tool for computational design allows users to turn any 3-D shape into a collapsible telescoping structure. New mathematical methods capture the complex and diverse properties of such structures, which are valuable for a variety of applications in 3-D fabrication and robotics -- particularly where mechanisms must be compact in size and easily deployable.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/6JhyLiFbD-A" height="1" width="1" alt=""/>Tue, 11 Jul 2017 11:24:28 EDThttps://www.sciencedaily.com/releases/2017/07/170711112428.htmhttps://www.sciencedaily.com/releases/2017/07/170711112428.htmInto the quantum world with a tennis racket
http://feeds.sciencedaily.com/~r/sciencedaily/computers_math/mathematics/~3/97oBQCRXiIM/170706113215.htm
Quantum technology is seen as an important future-oriented technology: smaller, faster and with higher performance than conventional electronics. However, exploiting quantum effects is difficult because nature's smallest building blocks have properties quite distinct from those we know from our everyday world. An international team of researchers has now succeeded in extracting a fault tolerant manipulation of quanta from an effect of classical mechanics.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/97oBQCRXiIM" height="1" width="1" alt=""/>Thu, 06 Jul 2017 11:32:15 EDThttps://www.sciencedaily.com/releases/2017/07/170706113215.htmhttps://www.sciencedaily.com/releases/2017/07/170706113215.htmUsing mathematical methods to study complex biological networks

Complex biological processes, such as the metabolism, often involve thousands of different compounds coupled by chemical reactions. These process chains are described by researchers as chemical reaction networks.

For democratic elections to be fair, voting districts must have similar sizes. When populations shift, districts need to be redistributed -- a complex and, in many countries, controversial task when political parties attempt to influence redistricting.

http://feeds.sciencedaily.com/~r/sciencedaily/computers_math/mathematics/~3/r-nKzzxdYHI/170620142906.htm
Plant diseases pose a serious threat to global food security, especially in developing countries, where millions of people depend on consuming what they harvest. In sub-Saharan Africa, one plant disease in particular -- maize lethal necrosis -- is ravaging one of the region's preferred crops for food, feed and income. But understanding its biology in order to manage the disease is difficult because the disease arises from two viruses interacting -- which is where mathematics comes into play.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/r-nKzzxdYHI" height="1" width="1" alt=""/>Tue, 20 Jun 2017 14:29:06 EDThttps://www.sciencedaily.com/releases/2017/06/170620142906.htmhttps://www.sciencedaily.com/releases/2017/06/170620142906.htmCow herd behavior is fodder for complex systems analysis

http://feeds.sciencedaily.com/~r/sciencedaily/computers_math/mathematics/~3/rBAJV3xub-U/170421103737.htm
Physicists have searched for deviations from standard quantum mechanics, testing whether quantum mechanics requires a more complex set of mathematical rules. To do so a research team designed a new photonic experiment using exotic metamaterials. Their experiment supports standard quantum mechanics and allows the scientists to place bounds on alternative quantum theories. The results could help to guide theoretical work in a search for a more general version of quantum mechanics.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/rBAJV3xub-U" height="1" width="1" alt=""/>Fri, 21 Apr 2017 10:37:37 EDThttps://www.sciencedaily.com/releases/2017/04/170421103737.htmhttps://www.sciencedaily.com/releases/2017/04/170421103737.htmFundamental unit of cell size in bacteria discovered

Skin color patterns in animals arise from microscopic interactions among colored cells that obey equations, say investigators.
