Blooms are 3D printed sculptures designed to animate as they rotate under a strobe light

Unlike a 3D zoetrope, which animates a sequence of small changes in objects, a bloom animates as a single, self-contained sculpture. The animation effect of the flower is achieved by progressive rotations of the golden ratio, phi (ϕ), the same ratio that nature uses to generate the spiral patterns we see in pine cones and sunflowers. The rotational speed and frequency of the flower’s strobe light are synchronized so that a flash is produced each time the flower rotates 137.5° (the angular version of phi). The particular shape and behavior of each bloom is determined by a unique parametric seed that I call phi-nomial.

Researchers remeasure gravitational constant

The gravitational constant G determines the strength of gravity—the force that makes apples fall to the ground or pulls the Earth in its orbit around the sun. It is part of Isaac Newton’s law of universal gravitation, which he first formulated more than 300 years ago. The constant cannot be derived mathematically; it has to be determined through experiment.

Over the centuries, scientists have conducted numerous experiments to determine the value of G, but the isn’t satisfied with the current figure. It is still less precise than the values of all the other fundamental natural constants—for example, the speed of light in a vacuum.

One reason gravity is extremely difficult to quantify is that it is a very and cannot be isolated: when you measure the gravity between two bodies, you also measure the effect of all other bodies in the world.
