Who controls our free speech online? What are the limits of free expression on social media? Index on Censorship launched Digitial Frontiers, the latest issue of its award-winning magazine, and the only publication dedicated to freedom of expression with an expert discussion on internet freedom.
I’ve contributed an article on how mobile technology plays a vital role in activism, spreading news, and bridging digital divides. An excerpt:
…it takes more than a computer to bridge the gap. The mobile phone is emerging as a powerful tool for social engagement; mobile technology and social media applications are playing a vital role in giving excluded groups a voice. And mobile technologies are almost ubiquitous. Around 70 per cent of mobile phone users are in developing countries, mostly in the global South, according to the UN agency the International Telecommunications Union.
Mobile phones are the first telecommunications technology in history to have more users in the developing rather than developed world – with no legacy infrastructure to service, new providers are jumping straight to mobile. Advances in technology have made mobile phones an indispensable part of development. New mobile platforms are simple and portable.
Many thanks to Global Voices community for the insight information and conversations with citizen media activists, and to Simon Phipps for contributing. Subscription options are available from Index and Amazon. The publication will be available to order from December 15th.

Science is but a perversion of itself unless it has as its ultimate goal the betterment of humanity – Nikola Tesla
One of the greatest people in the history of science, and the greatest inventor of the post industrial society, Nikola Tesla, is the visionary that many people have never even heard of or about his work. He could visualise the future inventions with the greatest facility. Numerous articles have been published, books have been written related to this magician of the science. There are many sources about this man who lit the world, and his developments.
Among many Tesla’s inventions, the most relevant that influence directly our everyday life include: radio, wireless telegraphy, remote control, robotics. He even photographed the bones of the human body. But the high point was the realisation of a childhood dream: harnessing the raging powers of Niagara Falls, and bringing light to the city. Tesla has over 700 patents to his name: invented the World First AC Generator which led to electrical development and enlightment of the world. This high frequency high volatage electricity is used today in many communication devices.
Also, Tesla’s Wireless power System including certain devices is now considered to be an untouched method to transmit electrical current without wires. Extraterrastrial Radio Transmitter – Teslascope, radio transceiver designed with the intention of communicating with extraterrestrial life on other planets. It received publicity after Tesla’s statement on the device was published by Time magazine in their July 20, 1931 issue celebrating Tesla’s 75th birthday.
We should mention here Tesla’s Earthquake Machine invention that probably many people never heard of. This is an excerpt from the New York World Telegram, July 11, 1935:
“Nikola Tesla revealed that an earthquake which drew police and ambulances to the region of his laboratory at 48 E. Houston St., New York, in 1898, was the result of a little machine he was experimenting with at the time which “you could put in your overcoat pocket.” The bewildered newspapermen pounced upon this as at least one thing they could understand and Nikola Tesla, “the father of modern electricity” told what had happened as follows:
Tesla stated, “I was experimenting with vibrations. I had one of my machines going and I wanted to see if I could get it in tune with the vibration of the building. I put it up notch after notch. There was a peculiar cracking sound. I asked my assistants where did the sound come from. They did not know. I put the machine up a few more notches. There was a louder cracking sound. I knew I was approaching the vibration of the steel building. I pushed the machine a little higher. “Suddenly all the heavy machinery in the place was flying around. I grabbed a hammer and broke the machine. The building would have been about our ears in another few minutes. Outside in the street there was pandemonium. The police and ambulances arrived. I told my assistants to say nothing. We told the police it must have been an earthquake. That’s all they ever knew about it.”
Nikola Tesla – called “the greatest geek who ever lived“, was not only the physicist, electrical engineer, philosopher, futurologyst, genius who lit the world, but above all – the humanist who created for the mankind.
Check out this very interesting TED presentation of Marco Tempest, who combined the projection mapping and a pop-up book, visually telling the story of Nikola Tesla.
