While there is no optimal nail shape for nail health, strength, and growth, it may help to cut fingernails straight across with slightly rounded edges. However, rounded edges on toenails can increase ...

They found another shape, related to the first, that meets an even stricter definition. Dubbed the "specter," the new shape tiles a plane in a pattern that never repeats without the use of mirror ...

Follow the steps below to make a Heart Shape in PowerPoint. Now, draw the rectangle on the slide. Go back to the Insert tab and insert a circle from the menu. Now, draw the circle on the rectangle and ...

A tetrahedron is the simplest Platonic solid. Mathematicians have now made one that’s stable only on one side, confirming a decades-old conjecture. In 360 BCE, Plato envisioned the cosmos as an ...

Researchers have discovered a "shape-recovering liquid" that appears to defy the laws of thermodynamics. The liquid, which is made up of oil, water and magnetized particles, consistently separates ...

After more than three centuries, a geometry problem that originated with a royal bet has been solved. Imagine you’re holding two equal-size dice. Is it possible to bore a tunnel through one die that’s ...

How few corners can a shape have and still tile the plane?” mathematician Gábor Domokos asked me over pizza. His deceptively simple question was about the geometry of tilings, also called ...
