symmetric

In the end, "it turned out that yes, you can actually valley polarize bulk materials that are central symmetric, because of the symmetry conditions," concludes Poborska.

While the head is generally radially symmetric -- it can be divided into two equal halves in multiple directions like a starfish or a pie -- the individual flowers can have different forms of symmetry.

Additionally, the symmetric structure of metal crystals at both ends has historically posed challenges in inducing these electrical effects.

Interestingly, they also found that the less symmetric the crystal is, the better the whole thing works.

Wearing a virtual reality headset, the user sees three arms: the right arm and hand, the left arm and hand, and a third arm between the two with a symmetric, six-fingered hand.
