Quantum Comb


Quantum physics is probably one of the most notorious subjects in science due to its hard mathematical nature and the absence of practical examples clearly governed by its laws.
One of the main ideas in quantum physics is the concept of quanta, these are small packages of energy which cannot be further divided and can therefore be seen as building blocks by which matter can be described.
At the university of Boston, a “multi molecular-comb” (see figure) has been developed which starts to rollover, back and forth, from its left side to its right when exposed to extreme temperature (-110°C) and a high energy electrical field (1,5 GHz).
Remarkably, the comb rolls over without actually rolling! So the comb basically goes from point A to point B without occupying the space in between.
Can you envision yourself moving from one place to another without really moving?
Beam me up scotty!

  1. Quite interesting and informative blog.The topic sentence is very "catchy".The conclusion is quite good and leaves the reader thinking.

    Good flow, style mix of science talk and informal talk. Good English.

    well done,
