Two’s company, three is a crowd: solving a Newtonian pickle

When two (or three bodies of different sizes and distances) orbit a center point, it’s easy to calculate their movements using Newton's laws of motion. However, if all three objects are of a comparable size and distance from the center point, a power struggle develops and the whole system is thrown into chaos. When chaos happens, it becomes impossible to track the bodies’ movements using regular math. Enter the three-body problem. Now, an international team, led by astrophysicist Dr. Nicholas Stone at the Hebrew University of Jerusalem’s Racah Institute of Physics, has taken a big step forward in solving this conundrum. Their findings were published in the latest edition of Nature.

In the past twenty years, both scientists’ understanding of the physical properties of quantum dots and their levels of control over these tiny particles have increased tremendously.  This has led to a widespread application of quantum dots in our daily lives—from bio-imaging and bio-tracking (relying on the fact that quantum dots emit different colors based on their size) to solar energy and next-generation TV monitors with exceptional color quality.
