  • Fibre Optics

    Fibre optic technology was first demonstrated in the 1840’s by Colladon and Babinet. Fibre optic tubes refract light within glass tubes with little loss of light over the length of the tube.

    In 1880 Alexander Graham Bell developed the technology to transmit voice signals over an optical beam. Bundled together, fibre optic cables are immune to electrical interference making them good for use in computer networking. Fibre optic transmissions are also much harder to snoop and are therefore considered more secure.

  • Graphene

    Graphene will completely revolutionise technology. Created at the University of Manchester, UK, graphene is a layer of graphite one atom thick. It is very strong, an excellent conductor of heat and electricity and is predicted to transform mobile devices. 

    Imagine a flexible cellphone or tablet –or ultra thin strong condom. The Gates Foundation has given $100,000 to research the development of a super thin and durable condom made of latex and graphene.

  • Cellphone technology

    The technology to enable cellphones to communicate from a base station was proposed in 1947, however the technology did not allow the phone to move out of range of the base station.

    A car phone call, using a rotary dial to make the call was first used in Sweden in 1956. The first mobile phone call was made from a Motorola phone in 1973.

    • Second that

      Their image gallery is a PITA. Looks like one of those galleries that were top tech in the 90s

    • Zdnet Overlooked Ajax??

      Ajax allows one to dynamically update specific area on web page.
      You dont have to refresh the entire page just to update a single slide.
      The technology is almost 10 years old !!!!

      If zdnet doesn't want to revamp its site, it should atleast provide a "view all" option (which is provided by default in other tech sites)

      • Agree

        Ajax belongs on this list. Obviously, nobody at zdnet has heard of it.

    • HERE HERE

      I've been complaining this to for the past few years.
      Must be entering one and exiting out the other ear.

  • The Fundemental one has been missed.....

    ELECTRICITY !

    Without which all of the above listed would not have been possible.

    • Sorry Fundamental !

      .

    • Agreed. And television and radio?

      Not even worth an honorable mention.

      It's not like we did anything useful with it, like watching the 1st human ever set foot on the moon or something as equally mundane....

      • Also missing: ENGINE

        Without the development of an engine, we would not have anything today. Not even electricity.

    • Spot on. To that I would add

      polymers. Electricity and plastics. Without them much of your world would disappear.

  • please no slideshows

    especially if they have the same pop ad over the top of every page that you cannot close, how irritating, I have given up looking at the content.

  • 11 amazing technologies that have totally changed our world for the better

    The headline implies to me that these are technologies that are *unequivocally* for the better. Not so sure that is the case for all of these mentioned but I'd add antibiotics.

  • Slideshow presentation

    ZDNET claims my explanation of why they use the slideshow presentation has words or phrases in it which indicate SPAM. A moderator has to approve my message. I guess this is how ZDNET keeps criticism of itself to a minimum.

  • Solar Cells in 1839?

    Becquerel wasn't even born until 1852!
    The fact checkers for this article should be fired.
    And both the author and editor need to be reprimanded!

    The internet AND the internet of things?
