The study of conformal (angle-preserving) maps has a long history. Since the earth is curved, any geographical map has to distort either angles or sizes. For navigation, conformality - preserving ...

A triangle isn't just a shape; it's a statement. But most brands get it wrong, falling for clichés about strength and dynamism. This brutally honest guide explains what triangles communicate—from ...

At the annual Bridges conference, mathematical creativity was on dazzling display. By Siobhan Roberts It’s not much of an exaggeration to say that the Dutch sculptor Rinus Roelofs organizes his life ...

The diagrams of shapes and objects in this topic are illustrative and not necessarily drawn to scale. Answers to practical problems are specified to an accuracy suitable for the context, for example, ...

The Helfrich theory of membrane bending, supported by molecular dynamics simulations, is a promising approach for evaluating mechanical properties of graphene nanosheets, report researchers from the ...

For more than five centuries, Leonardo da Vinci’s Vitruvian Man has invited admiration but also bafflement. With its harmonious symmetry of limbs outstretched in both a square and a circle, the ...

Persona 5 X answer to „What's an example of an arbitrary triangle? Give it your best shot” Source: Persona 5 The Phantom X, Developer: ATLUS, SEGA, Perfect World. Persona 5 The Phantom X is a ...

Abstract: The characteristics of equilateral-triangle resonator (ETR) and square resonator microlasers are reported, which are potential light sources in the photonic integrations. Based on the ...

Abstract: A simple circularly polarized (CP) equilateral triangular patch antenna for UHF (902-928 MHz) radio identification (RFID) reader applications is proposed. In this design, good CP radiation ...

For over a century, a simple yet tricky math problem had continued to baffle experts. Mathematicians struggled to find the fewest number of pieces needed to cut an equilateral triangle and rearrange ...

Mathematicians have proven that Henry Dudeney’s 1907 four-piece dissection of an equilateral triangle into a square is optimal. Using matching diagrams, researchers from JAIST and MIT showed that no ...
