It is possible to predict thoughts

Neuroscience has just made another huge progress: Researchers from Carnegie Mellon University, USA, got a computer that can read minds or almost that. Each volunteer received a list of words that should think. While the volunteer did it, a computer analyzed your brain activity (by means of a brain Machine Resonance system). The software learned to associate the terms to patterns of the brain activity – And after a while, could guess which words people were thinking

The system has a major limitation – It can only read the mind of a person, if that person is totally focused. The hardest part!

“Sometimes, during the experiment, the stomach of a volunteer snored, and this person thought ‘I’m hungry‘ ”, and it mixed the computer up. Says the scientist Tom Mitchell, responsible for the study.

Arms crossed on one’s chest helps you think better. Need to solve a difficult problem? Cross your arms! According to research recently published in Europe, the simple act of crossing the arms causes a subconscious in the brain – that increases up to 30% the capacity of concentrate.

Since the brain is our subject, find out if yours is in good health:

    *Which is the clock intruder?

   

    *The following groups of letters has a specific logic. But one of the second group belongs to the first. What is it?

First Group: S G J O C R B D P U

Second Group: A T V Q E H K F I Z


Answers:

    *What is the probability of taking one or six when playing a dice?

*Without looking at the watches, respond quickly: what color of the third one?

The fifth clock is the intruder, because is the only time that started with a vowel letter

The letters of the first group are round and the letters of the second are straight, but letter Q

The set one and six represent one-third of the possibilities

The color is green

 

Radio-Frequency Identification (RFID)

RFIDs are chips that use radio waves to send data to a reader - which in turn can be connected to the web.

This technology is just one of the current ways of allowing physical objects to go online - a concept dubbed the "internet of things", which industry insiders have shortened to IoT.

This is when not only your PC, tablets and smartphones can connect to the web, but also your car, your home, your jeans and even the sheep and cows on a farm.

Is not a little bit stranger? Well, is the new generation technology. These chips have the power to do something without your permission. Imagine, you have just bought a blouse, and this blouse start tweeting about your location as you cross the Central Park. At least is embarrassing.

Everything that you bought or that you have, if these things have this RFID chip you can be found wherever you are. The first impression of this technology is not that good, but thinking about the future it can almost save lives in an emergency.

In such a new context, the ethical worries are under consideration to what extent can surveillance of people be accepted. 

Either way, these RFID tags can improve the work of firefighters in fire, locating exactly where the people are. They may help to police work. And can be useful even helping up in traffic enforcement, since your car has a tag it can be picked up on radar, or placed for trailers.

These chips are also like a GPS for cars, they have sensors in them that send data online via a wireless low-power technology. With help of a special app on your smartphone, drivers can receive data from sensors installed in parking spaces, telling them where the closest free spot is. The car will update its and the driver's location. But have the negative point, the privacy issues. It's hard to predict how well all these issues will be addressed once the entire planet gets on the web.

Drift Trikes

Drift Trikes

The Big Wheel is a type of tricycle introduced by Louis Marx and Company in 1969. This toy usually made of plastic, with an oversized front wheel, that rides very low to the ground was very popular in the 1970’s in the United States, partly because of its low cost and partly because consumer groups said it was a safer alternative to the tradiciontal tricycle or bicycle.

Nowadays a new hobby involving the Big Wheel is becoming very popular around the world, it’s the Drift Trike. Created in the United States, this new hobby consist basically in downhill a road doing drift with modified Big Wheels. For who that don’t know what is Drift, this is a driving technique and a motorsport where the driver intentionally over steers, causing loss of traction in the rear wheels through turns, while maintaining vehicle control and a high exit speed. A car is drifting when the rear slip angle is greater than the front slip angle prior to the corner apex, and the front wheels are pointing in the opposite direction to the turn (e.g. car is turning left, wheels are pointed right or vice versa), and the driver is controlling these factors.

But now this “new toys” cannot be used by children, in a downhill the Drift Triker reach around 60 or 80 Km per hour. The modified Big Wheel has a BMX front with two plastic wheels in the rear to cause loss of traction. To get one, you can build yours, taking a BMX front and creating the back of the tricycle (There is a lot of places on the internet where you can search for instructions to build yours), or you can buy one, the price is about 298,333 dollars. The most of people who practice the drift trike wants only to have fun, but this hobby is becoming a extreme sport with championships all over the world.
