THE ORIGIN OF COMMUNICATION

How did people learn to speak?
Have you heard a baby trying to speak? It just makes noises that sound like 'goo' and 'gaa'. Well. the very first sounds made by early man were probably similar to the sounds made by babies!
Human beings probably learned to make sounds by imitating animals. This sound making ability was then passed on from parent to child by mothers making soothing sounds to their babies. Babies learned to repeat those sounds, which sound just like grunts and gurgles to us.
Gradually, certain sounds developed into specific meanings to those using them. Over hundreds, and perhaps thousands of years, man developed the ability to communicate through recognizable voice and speech as we know it today became the first form of communication between human beings.
Telepathy:
==========
Have you ever thought about a friend just a moment before the phone rang? Then, when you picked the phone up, it was the same friend you had just thought about! Is this a coincidence, or could it, perhaps, be a form of communication? Some scientists believe this phenomenon to be a form of communication called telepathy. In telepathy, there is direct transference of thought from one person to another, without using normal sensory channels.
Tele' means 'remote' and 'patheia' means 'to be affected by'. The field which studies certain types of paranormal phenomena such as telepathy is called parapsychology. They believe that telepathy is a type of communication, which we haven't completely explained yet. They are studying various reports about telepathy. But a technique, which shows statistically  significant evidence of telepathy on every occasion, has yet to be discovered. This lack of accurate and reliable evidence has led scepetics to argue that there is no scientific basis for the existence of telepathy at all. In short, there is no consensus about telepathy are real. Sceptics say that instances of what seem to be telepathy are explained as the result of fraud or self-delusion.
Micro Media Paper:
==================
Micro Media Paper is the electronic paper of the future. It will allow entire books to fit on a single sheet using futuristic printing technologies that will allow super cheap colour screens to be produced. In fact, a company called Lunar Design is planning to bring out these utra thin mini colour screens that would work on replacable batteries and which can be controlled with touch sensitive buttons.
VoWIFI:
=======
To understand what VoWifi is, you first have to understand two other terms - VOIP and WiFi.
VOIP which is the short form for Voice-Over Internet Protocols a facility that allows you to talk to people anywhere in the world through the internet. Wifi, on the other hand provides low cost internet access through wireless networking. Places from which you can access this wireless network are called WiFi 'hotspots'
WiFi has alot of advantages. Wireless networks are easy to set up, and are inexpensive. If you have been in an airport, coffee shop , library or hotel recently, chances are you have been right in the middle of a wireless network. Many people also use wireless networking to connect their computers at home and an increasing number of cities use the technology to provide low-cost Internet access to residents.
Most recently, the 'next big thing' has been to merge Wi-Fi with VOIP, producing one of the oddest terms you will ever see , VoWiFi! This stands for Voice over Wireless Fidelity. This simply means a Wi-Fi based VOIP service - or in even more general terms, a wireless based VOIP system.
VOIP over Wi-Fi has great potential as a means of reducing telephony costs.
VoWiBro:
========
This is another difficult sounding term which can be explained only if you know what WiBro is. WiBro is wireless broadband Internet technology being developed by the Korean telecom industry. With WiBro, Korean phones will tap into on 'always on' broadband connections that have a bandwidth much greater and faster than what is available now.
VoWiBro will be a great improvement on VoIP and the quality of service will be far superior due to the increased bandwidth and speed.
How can we talk through our hands:
==================================
Wouldn't it be incredible if your hand could become a mobile phone? Well, sometime in the future, it may. A technology is already being developed called Finger Whisper Technology, which could turn hands into handsets. By converting voice into vibration, then conducting vibration through the bones in the user's hand, the hand becomes a type of receiver.
Wrist Phone:
============
Very soon, people will be wearing their mobile phones on their hands in the form of a watch or bracelet. In fact, a product has already been developed that is not only a phone in watch, but it can also change into a standard handset shape! This mobile is called the wristomo and is an ultra modern mobile which features email and Web access.
You might have seen people using their mobile phones to take, send and receive pictures. In the future, a camera phone will allow users to display the images on their own bodies. These phones are already being developed in the form of chokers, charms and chains.

Internet Censorship: A Global Map of Internet Restrictions

The internet is a global medium playing a crucial role in our lives, acting as a source of instant information, entertainment, news, and social interactions. However, more than 65 percent of the world’s internet population, approximately 5.3 billion people, face some form of restriction in accessing this global information highway. As an exploratory study, let's uncover which countries impose the harshest internet restrictions and where citizens enjoy the most freedom of online info-access. The Worst Countries for Internet Censorship Surprisingly, not all the usual suspects take the top spots. North Korea, China, and Iran clinch the dubious distinction of having the worst internet censorship, scoring a maximum 11 out of possible 11 points. However, the inclusion of Iran in this group is due to its increased attempts to block VPNs and create a government-monitored VPN scheme. In these three countries, residents are denied access to Western social media, porn, and significant news me...
