Ferrolic is a desk clock which looks like an ever-evolving Rorschach test. Created by Zelf Koelman from the Eindhoven University of Technology, Ferrolic uses ferrofluid to tell the time, with this seemingly magical liquid moving gracefully around inside the clock as the minutes tick by.
Magnets are at the heart of much of our technology, and their properties
are exploited in a myriad ways across a vast range of devices, from
simple relays to enormously complex particle accelerators. A new class
of magnets discovered by scientists at the University of
Maryland (UMD) and Temple University may lead to other types of magnets
that expand in different ways, with multiple, cellular magnetic fields,
and possibly give rise to a host of new devices. The team also believes
that these new magnets could replace expensive, rare-earth magnets with
ones made of abundant metal alloys.
