Have you ever wondered what it would be like to make a dollar bill smoothie? Well popular science guru Steve Spangler certainly did and with the help of a super powerful neodymium magnet he demonstrates in the video below just how much iron you would get if you were stupid enough to drink the smoothie. The iron is present in certain magnetic inks used to print a fistful of dollars.

There’s iron in them there bills…you …

Sciencebase Exclusive - Careful experimentation and theoretical analysis of a double-slit experiment have finally quashed a controversy in fundamental physics – the complementarity-uncertainty debate.

Ever since the catflap to the quantum world was opened up to us and Schrödinger’s feline friend was idiomatically let out of the bag, to mix a metaphor or two, there have been more questions and controversies raised than conundrums solved in the world of the very, very small. How …

Quantum Dots and Spin Pumps

Spin pumped quantum dot

It is not so long ago, that the first thing that sprang to mind when one read the phrase ‘quantum dot’ is some rather esoteric and complicated aspect of avant garde physics. This is still partly true, there is some rather complex experimental work underway underpinned by even more complex theoretical work investigating the bizarre properties of tiny devices that can trap a single electron in zero-dimensions.

Practical …
