Imagine playing video games together with your friends seated at different places while communicating only with your minds. Researchers from University of Washington including one of Indian-origin have developed a method just to do that, brining telepathic communication a step closer to reality.
In the study, published in the Nature journal Scientific Reports, the researchers showed that three people can play a Tetris-like game using a brain-to-brain interface.
This is the first demonstration of two things — a brain-to-brain network of more than two people, and a person being able to both receive and send information to others using only their brain.
“We wanted to know if a group of people could collaborate using only their brains. That’s how we came up with the idea of BrainNet: where two people help a third person solve a task,” said corresponding author Rajesh Rao.
As in Tetris, the game shows a block at the top of the screen and a line that needs to be completed at the bottom.
Two people, the Senders, can see both the block and the line but can’t control the game.
The third person, the Receiver, can see only the block but can tell the game whether to rotate the block to successfully complete the line.
Each Sender decides whether the block needs to be rotated and then passes that information from their brain, through the Internet and to the brain of the Receiver.
Then the Receiver processes that information and sends a command — to rotate or not rotate the block — to the game directly from their brain, hopefully completing and clearing the line.
The team asked five groups of participants to play 16 rounds of the game. For each group, all three participants were in different rooms and couldn’t see, hear or speak to one another.
The Senders each could see the game displayed on a computer screen. The screen also showed the word “Yes” on one side and the word “No” on the other side.
Beneath the “Yes” option, an LED flashed 17 times per second. Beneath the “No” option, an LED flashed 15 times a second.
“Once the Sender makes a decision about whether to rotate the block, they send ‘Yes’ or ‘No’ to the Receiver’s brain by concentrating on the corresponding light,” said first author Linxing Preston Jiang.
The Senders wore electroencephalography caps that picked up electrical activity in their brains.
The lights’ different flashing patterns trigger unique types of activity in the brain, which the caps can pick up.
So, as the Senders stared at the light for their corresponding selection, the cap picked up those signals, and the computer provided real-time feedback by displaying a cursor on the screen that moved toward their desired choice.
The selections were then translated into a “Yes” or “No” answer that could be sent over the Internet to the Receiver.
“To deliver the message to the Receiver, we used a cable that ends with a wand that looks like a tiny racket behind the Receiver’s head. This coil stimulates the part of the brain that translates signals from the eyes,” said co-author Andrea Stocco. (IANS)

An energy meter, also known as a Watt-Hour Meter, is a device that monitors the level of electrical energy or gas consumed by users. Utilities are among the agencies that place these devices in various locations such as houses, businesses, organizations, and commercial properties to charge for the power consumed. You can always know how much is gas or electric cheaper by contacting a utility company.
Electronic Energy Meters
When compared to traditional mechanical meters, these types of measuring equipment are more accurate, have a faster processing time, and are more trustworthy. When attached to a source, it uses less power and begins measuring immediately.
Analog or digital meters are both possible. Analog meters transform energy to proportionate frequency or pulse rate, which is then combined by counters inside the device. A high-end processor directly calculates power in a digital electric meter.
Logic circuits combine the power to obtain the energy as well as for testing and certification purposes. The frequency or pulse rate is then calculated.

Smart Energy Meters
It is a cutting-edge metering technique that entails installing intelligent meters that read, process, and relay information to clients. It monitors energy usage, changes the supply to consumers remotely, and digitally manages the maximum energy usage.
For greater performance, smart metering systems make use of modern metering infrastructure system technology. These meters limit the number of times you have to go to the place to get your monthly reading.
In these smart meters, modems are utilized to enable communication technologies like phone, wireless, fiber cable, and power line communications. Another benefit of smart metering is that it eliminates the possibility of tampering with energy meters, which could lead to unlawful power usage.

Working of The Meter
The conventional electric meter looks like a clock and keeps track of how much electricity you consume. A series of microscopic gears inside the meter moves as your home takes electricity from the power wires. The numbers on your meter that you notice when you look at it indicate the number of revolutions.
The quantity of electricity utilized determines the speed at which the rotations occur. The velocity of moving gas in the pipeline is measured by a gas meter. As the gas flow rate increases, the dials speed up.

How Often is Meter Read?
Unless the meter is a consumer-ready meter, the government will demand utility companies read user meters quarterly. If the consumer checks the meter, the utility is asked to read it at least once a year. Almost every month, many utilities try and read their customers' meters.
If the meter isn't read, the utility might issue an estimated charge based on the previous usage. Keep bushes and plants away from the meter and allow access to the meter reader if your meter is within your home. All utilities demand their meter readers to have an employment ID as a security measure.

Responsibility of Meter
The utility provider is in charge of meter installation as well as the gas and electric lines that go up to the meter. The wires from the meter to the customer's premises are his responsibility.Please call your gas or electric utility if your meter is broken or displays evidence of tampering. Manipulation with a meter is prohibited and may result in service termination, legal punishment, or both.

A hilarious rhyme that children often chant cheerily while jumping around, Jack and Jill is another example of the dark history covered up in light-hearted rhyme. Instead of England though, this is a rhyme that sheds light on the history of France.
Unlike other rhymes, the rhyme is part fiction and part history, since only the first two lines can be taken as an allusion to the past.
"Jack and Jill went up the hill to fetch a pail of water,
Jack fell down and broke his crown,
And Jill came tumbling after."
King Louis XIV ruled over France in the late 18th century and was called out for treason. He had failed to uphold the economy of France. His spouse Marie Antoinette was an equally powerful influence in the monarchy but could not do anything when her husband was convicted.

The French are famous for the guillotine, and Louis XIV was beheaded on this device. This act of executing a monarch is why the rhyme has the line "Jack fell down and broke his crown". The guillotine, at this point in history, was kept outside the city, and the journey to it was long and tedious. It was ideally located on a hill, so that the entire city of Paris could witness the execution of the accused.
Louise XIV is believed to have been dressed and taken on the long journey up to the guillotine, where his hair was cut off and he had to renounce his authority. He bid farewell to his friends and was followed up the hill by a crowd holding pikes and bayonets, to prevent his escape. He was then executed as the last monarch of France.

A few months later, when the hue and cry of Louis XIV's death has died down a little, but the political situation of France was no better, his wife, Marie Antoinette was also executed at the guillotine for her role in the fall of France. And this event alludes to the line, "Jill came tumbling after".
The rest of the rhyme is a fictional account of a moralistic idea for children, as a way to tell them to be careful of where they engage in play. Since a large part of the rhyme seems like a story of two children who have had an accident in play, that is how the rhyme has survived and the history behind it, has been forgotten.
