Mathematicians from National University of Singapore and Nanjing University uncover a new mathematical method by challenging age-old assumptions of renowned mathematicians T. Aubin, A. Chang, and P. Yang Mathematically, is it possible to continuously deform a rough sphere into a perfect sphere? Under what situations can we solve the differential equations? Professor Xu Xingwang of the Department of Mathematics at National University of Singapore (NUS), along with Dr Chen Xuezhang from...

VANCOUVER, Jan. 31, 2012 /PRNewswire/ - Radius Gold Inc. (TSX-V: RDU) announces that as a result of the completion of Radius's spin out of assets to Rackla Metals Inc., the common share purchase warrants of Radius have been adjusted based on the fair market value of Radius and Rackla at the time of completion of the spin out. Accordingly, the exercise price of all common share purchase warrants outstanding in Radius have been reduced to 73% of the original exercise price,...

AMSTERDAM, January 10, 2012 /PRNewswire/ -- Elsevier, a world-leading provider of scientific, technical and medical information products and services, announced it will organize an extra Tetrahedron Symposium in 2012. In an effort to bring the world class speakers in bioorganic and organic medicinal chemistry closer to researchers, Tetrahedron's annual symposium will this year be held in two locations, one in Europe and one in Asia. Professor Chi-Huey Wong, Academia...

According to a new study, crystals found in Russia's Koryak mountains two years ago may have come from space. Quasicrystals had only been created in the lab before geologists found them in rocks in Russia. These crystals are unusual and were first described in the 1980s by Israeli research Daniel Shechtman. Quasicrystals break rules of symmetry that apply to conventional crystalline structures, and they also exhibit different physical and electrical properties. Luca Bindi from...

Namibian authorities have recently announced the discovery of a large metallic ball which they say fell from the sky and landed in the country´s remote northern grasslands in mid-November. After conducting a number of tests on the mysterious sphere, the baffled Namibian government opted to contact NASA and the European Space Agency (ESA) this week. Following their initial examinations of the object, the nation´s police deputy inspector general Vilho Hifindaka stated that the...

Researchers at Brown and Johns Hopkins universities have found optimal configurations for creating 3-D geometric shapes – like tiny, highly simplified geodesic domes that assemble by themselves. The Brown team developed the algorithmic tools, and the Johns Hopkins team tested selected configurations. The research may lead to advances from drug-delivery containers to 3-D sensors and electronic circuits. Results published in Proceedings of the National Academy of Sciences. Material...

The Nobel prize for chemistry was awarded to an Israeli scientist whose work was once ridiculed for being out of line with received thinking. Daniel Shechtman, from the Israel Institute of Technology (Technion), won the entire $1.5 million 2011 Nobel prize for chemistry on Wednesday for discovering different ways in which atoms could be packed together in solid materials. His work has opened the door for experiments in the use of quasicrystals. The Royal Swedish Academy of Sciences said...

Chemists have created a molecular polyhedron, a ground-breaking assembly that has the potential to impact a range of industrial and consumer products, including magnetic and optical materials. The work, reported in the latest issue of the journal Science, was conducted by researchers at New York University's Department of Chemistry and its Molecular Design Institute and the University of Milan's Department of Materials Science. Researchers have sought to coerce molecules to form regular...

VANCOUVER, May 27, 2011 /PRNewswire/ - Radius Gold Inc. (TSX-V: RDU) is pleased to announce that the Board of Directors of the Company has unanimously approved a spin out transaction (the "Spin Out") whereby Radius will transfer all of its Yukon and Alaskan property assets and $1.0 million in cash to a new company ("Newco") in return for Newco shares and warrants, the majority of which will then be distributed to Radius shareholders by way of a plan of arrangement. The...

Music producers have for decades had electronics tricks at their disposal for improving a recorded vocal performance. They can add a little reverb or echo to bolster a weak rendition, use effects such as phasing and delay to add color to the vocal, fix duff notes with auto-tuning or even reprogram a whole melody line in software. In recent years, voice synthesis for converting text to spoken word has improved considerably but combining that technology with auto-tuning capability allows...

Geometry is a branch of mathematics that is concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the geometry field is called a geometer. Geometry arose independently in numerous early cultures as a body of practical knowledge concerning areas, lengths, and volumes, with elements of a formal mathematical science emerging in the West as early as Thales. By the 3rd century BC, geometry was put into an axiomatic form by...

Trigonometry, from the Greek trigonon, meaning triangle, and metron, meaning measure, is a branch of mathematics that studies the relationships involving lengths and angles of triangles. The field came about during the 3rd century BC from applications of geometry to astronomical studies. The 3rd century astronomers first noted that the lengths of the sides of a right triangle and the angles between those sides have fixed relationships: that is, if at least the length of one of those sides...

In geometry, a polygon is traditionally a plane figure that is bounded by a finite chain of strait line segments closing in a loop to create a closed chain or circuit. These line segments are called edges or sides, and the points where two of these edges meet are the polygon’s vertices or corners. The inside of the polygon is occasionally called its body. An n-gon is a polygon with n sides. A polygon is a 2-dimensional instance of the more general polytope in any number of dimensions....

In Euclidean geometry, a rhombus, plural rhombi or rhombuses, is a simple quadrilateral whose four sides all have equal length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are the same in length. The rhombus is frequently called a diamond, after the diamonds suit in the playing cards, or a lozenge, though the former sometimes is in reference specifically to a rhombus with a 60 degree angle, and the latter occasionally is in reference specifically...

Geometric and Functional Analysis (GAFA) is a bimonthly published mathematical journal published by Birkhauser, an independent division of Springer-Verlag. GAFA was founded in 1991 by Mikhail Gromov and Vitali Milman. The idea for the journal was inspired by the long-running Israeli seminar series “Geometric Aspects of Functional Analysis (GAFA)” of which Milman was one of the main organizers. The journal retained the same acronym as the series to stress the connection between the two....
