Scientists Store One Bit of Data on a Single Atom — Future of Data Storage

Imagine a pocket-sized hard drive capable of storing the entire list of 35 Million Songs?

This isn’t yet practical, but IBM has just taken a big step towards improving computing technology: IBM researchers just discovered a way to store data on a single atom.

Data storage is undergoing dramatic evolution, recently researchers successfully stored digital data — an entire operating system, a

200KV Capacitor Uses Cake Pan and Bowl

[PhysicsGirl] posts videos that would be good to use in a classroom or homeschool environment. She recently showed a 200KV capacitor made from a cake pan, a bowl, and some other common items (see video, below).

One of the most interesting things about the project was how they charged the capacitor. A PVC pipe and some common hardware made a wand that they’d charge by rubbing a foam sleeve up and down against the dome formed by a metal bowl. We might have used a cat, but there’s probably some law against that.

To discharge, they used the end of …read more
