Dyson, inventor of bag-less vacuum and super-fast hand drier, has invented the blade-less fan:

Our New Dyson Fan

How it works:
The Dyson fan has a conventional motor and fan blade in the base. The air flows from the base into the upper ring structure. No magic there. The magic is in the ring structure, where the air flows out a slit around the front edge of the ring. Here a process called inducement is put to work. The air flowing out of the slit recruits surrounding air because of the configuration of the slit. So now there is more air flowing through the ring structure than there would be from the base fan alone. Dyson claims that inducement creates a 15x amplification in airflow. Hence the name “Dyson Air Multiplier”.

(I agree)

another thoughtful one! i'll keep an eye on your posts in shayari.

oye hoye, ki gal keeti aa... POST MORE!

mnno ja na mnno jina miss pooja di burayi karoge ona e o jada hit ho jaugi haha

asi PJ te ohdi gal esey karke karde aa, asi ohnu hor hit kar dena lol

Miss Pooja dantmanjan bahut changi cheez aa

Jede PJ lok knowledge section nu pasand karde, ona lai khabar:


'Thirst for knowledge' may be opium craving

The brain's reward for getting a concept is a shot of natural opiates
Neuroscientists have proposed a simple explanation for the pleasure of grasping a new concept: The brain is getting its fix.

The "click" of comprehension triggers a biochemical cascade that rewards the brain with a shot of natural opium-like substances, said Irving Biederman of the University of Southern California. He presents his theory in an invited article in the latest issue of American Scientist.

"While you're trying to understand a difficult theorem, it's not fun," said Biederman, professor of neuroscience in the USC College of Letters, Arts and Sciences.

"But once you get it, you just feel fabulous."

The brain's craving for a fix motivates humans to maximize the rate at which they absorb knowledge, he said.

"I think we're exquisitely tuned to this as if we're junkies, second by second."

Biederman hypothesized that knowledge addiction has strong evolutionary value because mate selection correlates closely with perceived intelligence.

Only more pressing material needs, such as hunger, can suspend the quest for knowledge, he added.

The same mechanism is involved in the aesthetic experience, Biederman said, providing a neurological explanation for the pleasure we derive from art.

"This account may provide a plausible and very simple mechanism for aesthetic and perceptual and cognitive curiosity."

Biederman's theory was inspired by a widely ignored 25-year-old finding that mu-opioid receptors – binding sites for natural opiates – increase in density along the ventral visual pathway, a part of the brain involved in image recognition and processing.

The receptors are tightly packed in the areas of the pathway linked to comprehension and interpretation of images, but sparse in areas where visual stimuli first hit the cortex.

Biederman's theory holds that the greater the neural activity in the areas rich in opioid receptors, the greater the pleasure.

In a series of functional magnetic resonance imaging trials with human volunteers exposed to a wide variety of images, Biederman's research group found that strongly preferred images prompted the greatest fMRI activity in more complex areas of the ventral visual pathway. (The data from the studies are being submitted for publication.)

Biederman also found that repeated viewing of an attractive image lessened both the rating of pleasure and the activity in the opioid-rich areas. In his article, he explains this familiar experience with a neural-network model termed "competitive learning."

In competitive learning (also known as "Neural Darwinism"), the first presentation of an image activates many neurons, some strongly and a greater number only weakly.

With repetition of the image, the connections to the strongly activated neurons grow in strength. But the strongly activated neurons inhibit their weakly activated neighbors, causing a net reduction in activity. This reduction in activity, Biederman's research shows, parallels the decline in the pleasure felt during repeated viewing.

"One advantage of competitive learning is that the inhibited neurons are now free to code for other stimulus patterns," Biederman writes.

This preference for novel concepts also has evolutionary value, he added.

"The system is essentially designed to maximize the rate at which you acquire new but interpretable [understandable] information. Once you have acquired the information, you best spend your time learning something else.

"There's this incredible selectivity that we show in real time. Without thinking about it, we pick out experiences that are richly interpretable but novel."

The theory, while currently tested only in the visual system, likely applies to other senses, Biederman said.
