Brain Zapping Improves Math Ability202

sciencehabit writes "If you are one of the 20% of healthy adults who struggle with basic arithmetic, simple tasks like splitting the dinner bill can be excruciating. Now, a new study suggests that a gentle, painless electrical current applied to the brain can boost math performance for up to 6 months. Researchers don't fully understand how it works, however, and there could be side effects." We've covered various other potential benefits to having your brain shocked.

That reminds me of three men in a boat [cleavebooks.co.uk], where the narrator reads an advert for liver pills.

In the present instance, going back to the liver-pill circular, I had the symptoms, beyond all mistake, the chief among them being "a general disinclination to work of any kind."

What I suffer in that way no tongue can tell. From my earliest infancy I have been a martyr to it. As a boy, the disease hardly ever left me for a day. They did not know, then, that it was my liver. Medical science was in a far less advanced state than now, and they used to put it down to laziness.

"Why, you skulking little devil, you," they would say, "get up and do something for your living, can't you?" — not knowing, of course, that I was ill.

I remember reading this as a kit and lamenting that my teachers also had no idea that this was a medical condition. But then he goes on:

And they didn't give me pills; they gave me clumps on the side of the head. And, strange as it may appear, those clumps on the head often cured me — for the time being. I have known one clump on the head have more effect upon my liver, and make me feel more anxious to go straight away then and there, and do what was wanted to be done, without further loss of time, than a whole box of pills does now.

Swans!

Neither mA nor Volts is a measure of power. A standard AA cell produces about 1.5 Volt of potential across its terminals. Depending on the application, the current draw (Amps) can be anywhere from a fraction of a microamp to around 1 Amp. The power (Watts) that a AA cell delivers is the voltage time the current, and can be anywhere from a fraction of a mircowatt to more than 1 Watt. The energy (Joules) that a AA cell delivers over its lifetime is the power mu

Memorize your multiplication tables or I shalll shock you again!

Reminds me of a story:

Little Zachary was doing very badly in math. His parents had tried everything...tutors, mentors, flash cards, special learning centers, and more.

In short, everything they could think of to help his math.

Finally, in a last ditch effort, they took Zachary down and enrolled him In the local Catholic school. After the first day, little Zachary came home with a very serious look on his face. He didn't even kiss his mother hello. Instead, he went straight to his room and started studying.

Books and papers were spread out all over the room and little Zachary was hard at work. His mother was amazed. She called him down to dinner.

To her shock, the minute he was done, he marched back to his room without a word, and in no time, he was back hitting the books as hard as before. This went on for some time, day after day, while the mother tried to understand what made all the difference.

Finally, little Zachary brought home his Report Card. He quietly laid it on the table, went up to his room and hit the books. With great trepidation, His Mom looked at it and to her great surprise, Little Zachary got an 'A' in math.

She could no longer hold her curiosity. She went to his room and said, 'Son, what was it? Was it the nuns?' Little Zachary looked at her and shook his head, no. 'Well, then,' she replied, Was it the books, the discipline, the structure, the uniforms? WHAT WAS IT?'

Little Zachary looked at her and said, 'Well, on the first day of school when I saw that guy nailed to the plus sign, I knew they took their math seriously.'
