Graphite Found to Exhibit Surprising Quantum Effects

So all this time, when it looked like I was doodling anime characters in class, I was really designing the next generation of circuit board technology? Sweet!

Connect the dots, La la la la!

" Geim’s team found that they do not slow down, even at very low temperatures."

I thought conductors tended to superconduct at very low temperature. Is this in anyway linked to superconductivity (where electron speed equals c I believe).

And you don’t even need a soldering gun! :smiley:

Is there anything carbon can’t do?

“Why, I can make a hat or a brooch or a pterodactyl!”

“It’s a dessert topping! It’s a floor wax! It’s BOTH!”

“…used adhesive tape to strip graphite down to a layer just one atom thick…”

…yet it still stubbornly refused to pick up the stray lint and cat hair from their black clothing. Stumped, the 3M researchers went back to the drawing board.

      • I once had the idea to make conductive “crayons”, that students could literally draw out working circuits with. You could have P- and N-conductive color for making semiconductors, regular-conductive color, resistive color, capacitors, and inductors… ehhh… -I hadn’t figured inductors out as of then.
  • It was a brilliant idea, except for the fact that nobody anywhere seems to know how to make a crayon conductive and also not horribly toxic. …-And also, to make a working Z80-era CPU, you’d need a sheet of paper about four hundred feet square.

So maybe that’s the reason I seem to attract an undue amount of static electricity shocks. I have a tiny piece of pencil lead in my left knee. I tell people it’s my tattoo- of the world as seen from a great distance.
