for all you IT hardware types out there:

The dimensions of the head are impressive. With a width of less than a hundred nanometers and a thickness of about ten, it flies above the platter at a speed of up to 15,000 RPM, at a height that’s the equivalent of 40 atoms. If you start multiplying these infinitesimally small numbers, you begin to get an idea of their significance.

Consider this little comparison: if the read/write head were a Boeing 747, and the hard-disk platter were the surface of the Earth:

    * The head would fly at Mach 800
    * At less than one centimeter from the ground
    * And count every blade of grass
    * Making fewer than 10 unrecoverable counting errors in an area equivalent to all of Ireland.

they are no so impressive when educated with Sammy Sledgehammer

That is a truly excellent fascinating fact. I will be boring all and sundry with that one in the smoking shelter tomorrow  

Good post

May I congratulate you on your excellent use of sarcasm.  

It was sarcasm, wasn't it?

Nope. Not at all.

A fascinating fact should be exactly that. It was.

It should also completely fail to enrich your life one jot. Tick in the box there too.

And I will probably be telling those that listen in the smoking shelter tomorrow. (Although I will pick my audience carefully...)

Straight up - good post

Thanks! I shall endeavour to provide more fascinating facts in due course!
