    Predict your ponytail

    Science is amazing. Now you can predict the shape of your ponytail if you know the stiffness and the waviness of your hair and the gravity.

    Physicists have come up with an equation that explains and predicts the shape of a ponytail.

    The report in Physical Review Letters journal could help scientists better understand natural materials, such as wool and fur.

    The new equation takes into account the stiffness of hairs, the effects of gravity and the presence of random curliness or waviness.
    I used to rely on mirrors to check on my ponytail but this is way cooler :=)
