ஏனென்றால்?



நான் ஓவியங்களை விடவும்
தூரிகையை ரசிக்கின்றேன்;
ஏனென்றால்?
அவை ஓவியத்தின்முகவரியில்
தன்னைத் தொலைத்துவிடுவதால்


நான் மலர்களை விடவும்
காம்புகளை ரசிக்கின்றேன்;
ஏனென்றால்?
அவை மலர்களைமுன்நிறுத்தி
தன்னை மறைத்துக் கொள்வதால்


நான் வெற்றிகளைக் காட்டிலும்
தோல்விகளை ரசிக்கின்றேன்;
ஏனென்றால்?
அவற்றில் முற்றிவிடும்
தலைக்கனம்ஏதுமில்லை என்பதால்.


நான் இளமையை விடவும்
முதுமையை ரசிக்கின்றேன்;
ஏனென்றால்?
அதனிடம் இழப்பதற்கு ஏதுமில்லை என்பதால்


பற்றுக்கள் அறும்வேளை
பாரங்கள் குறைகிறது
பாரங்கள் விடும்வேளை
பறப்பது சுகமாகிறது

HOW TO FEED YOUR BUSINESS DREAMS




Take The Time To Grow Your Business

Got big dreams for your business? Eager to succeed? Fantastic! Now sit down and figure out how you are going to make that happen. You can’t cut to the front of the line or skip steps. Use your excitement to keep focused on your plan. Don’t use it to jump ahead and try to short circuit the process.
Every day I see small business owners jump ahead in a couple of areas in their business. From marketing to networking to pricing you can do real damage to your future if you go to fast.
1. Marketing
Before you sign up to advertise in a magazine, pay for Google ads, or buy air time, ask yourself some key questions:
  • Who is your audience?
  • Where is your audience?
  • What is the best way to transmit your message?
Taking the time to answer these questions will help you avoid spending money in the wrong places. Think about it this way.  If you sell to businesses, does it make sense to put an ad in a consumer magazine or neighborhood paper? Not really. Sure, you can tell yourself that your target market will be reading that document. However, they won’t be reading it with an eye for what you are offering. Your message will be lost on them. That is not the best way to spend your marketing dollars.
Don’t allow yourself to be swayed by the salesperson or your associates. You must do your due diligence before signing on the dotted line.
Example: I have two friends who started an organization called Positive Thinkers Network. After it had been in operation for about a year they decided to launch The Positive Times, a periodical that goes into homes and has only good news stories in it. When the salesperson reached out to me about advertising in it my first reaction was to sign up. After all, I like the owners and wanted to support them if I could. My heart said ‘do it.’ When I took a moment to consider this I realized that it just wasn’t the place for me to advertise because I sell to businesses, not consumers. As much as I wanted to support my friends, this was not a good marketing decision. So I respectfully declined.
2. Networking
There are tons of opportunities to network, on and off line. You could be doing it all day and night, every day. However, that would not be the best use of your time. Once again you have to ask yourself some questions starting with what do you hope to accomplish. It is my opinion that networking is building relationships with people who may or may not need what you have to sell.
At the same time, since time is precious, you want to meet the people who can introduce you to your target. Visiting various events and groups to get a sense of them can be a very valuable exercise. Just pay attention while you are there.
Example: I have a client whose target market is CPAs and attorneys. I have another client whose target market is busy professionals and salespeople who like to thank their clients. Where they will network will be different. The first client should be around business owners as they are the people most likely to have CPAs and attorneys. The second client would do well with business owners but would also do well in a group of salespeople.

World Wildlife Fund’s Poster



How many endangered animals can you spot in the World Wildlife Fund’s poster warning about deforestation?


 

Now you see them, now you don't - a striking portrayal of animals hidden in a rain forest which could all be wiped out as a result of deforestation are revealed in a poignant poster.
The poster from wildlife campaigners WWF shows everything from a lion to an elephant which have all been skilfully concealed in a jungle vista.
The animals are camouflaged as if they are part of the tropical and lush undergrowth, but in fact what appears to be a tree trunk or vine is actually a lot more.
Hidden depths: At first glance this looks like a picturesque image of a leafy rainforest

Endangered: The camouflaged animals can be seen marked with a red outline revealing those most affected by deforestation

The poster - part of campaign to highlight the damage of deforestation - was aimed at getting the public to take a moment to consider how many animals could be lost if deforestation continues at it's current rate.
Forests still cover around 30 percent of the world's land surface but they are being felled at a rate of nearly 30 square miles a year - roughly an area the size of Panama.

During the past 40 years, close to 20 percent of the Amazon rain forest has been cut down more than in all the previous 450 years since European colonisation began
 
This poster was plastered along busy stretches of the Paris Metro underground and featured in Lonely Planet magazine.
Marine Garcia, from design agency Marcel, said four artists worked meticulously on the poster to try and conceal the animals from the public 
just enough to make them work to see them.
She said: 'The point of this poster was to let people know that deforestation does not only kill trees, it is also killing wildlife too.
'The animals are hidden because soon we might really not be able to see them again.'

Future Tanks Will Be Cooler, and Thus Invisible to Thermal Detection


By David Hambling

Thermally Invisible Tank Peter Bollinger
Tanks are easy to see by day and, since they generate a lot of heat, they are also easy to spot at night, at least for those equipped with infrared imaging equipment. In August, the British company BAE Systems unveiled its new Adaptiv system, which hides a tank’s heat signature beneath hundreds of electrothermal cells bolted to the vehicle’s exterior.
Infrared sensors detect the pattern of heat reflected by a tank’s immediate surroundings and, just as a processor guides pixels in a computer screen to form an image, adjust the temperature of individual cells to collectively form a heat signature that matches the environment. In infrared, the tank appears to disappear into the background. BAE says the system will be battle-ready in two years.

HEAT-SENSITIVE CELLS

The Adaptiv system’s hundreds of 5.5-inch hexagonal cells are heated or cooled with electric current to create customized heat signatures. The system is dynamic, meaning a tank operator could match the vehicle’s heat signature to its surroundings when stationary but assume the signature of a preprogrammed object, such as a car or a cow, when moving. When friendly fire is a concern, operators could also exaggerate a tank’s signature to prevent confusion. BAE has already started testing its next generation of cells, which will include an undisclosed coating that can change color and brightness.

FAST-COOLING EXHAUST

Engine exhaust may be too hot for Adaptiv to conceal completely. But borrowing techniques from stealth aircraft construction, tank manufacturers could incorporate broad and flat vents that produce ribbons of exhaust, which mix more rapidly with cool air. The vents would also be low to the ground so that exhaust would be disguised by the heat signature of the surrounding vegetation.

QUIETER ENGINES

The Army has been testing hybrid engines in combat vehicles. In tanks, a silent electric engine could be flipped on for stealth combat missions.

MIT's Nano-Bio-Bandage Can Stop Your Bleeding Almost Immediately

Bleeding out on the battlefield--far from the trauma wards and triage units that might save their lives--is a scenario that soldiers simply have to live with (and try like hell to avoid). But thanks to ananoscale breakthrough at MIT, the chances of it happening could be significantly reduced. Researchers there have created a nanoscale coating that can stop bleeding nearly instantaneously using a clotting agent already found naturally in blood.
That agent, called thrombin, is coated onto sponges that can be easily packed by soldiers and field medics (or civilian medical personnel for that matter) and shaped to fit just about any kind of wound. Those pre-coated sponges are a pretty big improvement over tourniquets and gauze, which are limited in their ability to stop every kind of bleeding. Tourniquets obviously can’t be used on many parts of the body (the neck is a good example), and other glues and chemically treated bandages designed for dressing battlefield wounds come with their own complications and shortcomings.

Thrombin, on the other hand, is already used by the body to stop bleeding. Civilian hospitals also use it already, but it’s in liquid form so sponges must be soaked immediately before they are applied to the wound, making them impractical for the battlefield. MIT’s sponge instead uses a spray-on biological nanoscale coating using alternating layers of thrombin and tannic acid, which results in a film that contains a large amount of functional thrombin with a shelf life that makes it feasible to pack them into the field. Both substances are already FDA approved, the researchers say, which means the sponges could quickly find their way into wider use.
That’s good news for soldiers, and potentially good news for anyone who sustains a trauma far from the emergency room. The MIT lab is now working on a sponge that combines a blood-clotting coating with an antibiotic layer in a single sponge to help fight off infection even as a dressing stops the initial bleeding.

Hands-On Impressions of the Lumia 900, Nokia's Great New Windows Phone




Give me this phone
Lumia 900 Hands-On Dan Nosowitz
I just got back from Nokia's booth here at CES in Las Vegas, where things are decidedly focused on Windows Phone. And with good reason; the Lumia 800, which is available in Europe and on other continents in which I do not live, is the best Windows Phone on the market, and the new 900, announced officially just yesterday, is set to become the best Windows Phone in America. I played with the Lumia 900 for a little while, and came away reassured: this phone is just as good as I expected.
The Lumia 900 differs mostly from its predecessor in size. It's a 4.3-inch-screened phone, compared to the perfectly usable but slightly small Lumia 800, which clocked in at 3.7 inches. There's a slight sacrifice in aesthetics with that; in the 800, there was this cool effect where the curved screen seemed to fade away into the body of the phone, sort of like an infinity pool, due to the curved glass front and lack of visible bezel. The 900, on the other hand, does have a bezel--the Nokia rep told me they were a little unsure about how folks would respond to it. I found it not quite as nice-looking as the melty screen on the 800, but not glaring enough that it really takes away from the rest of the phone.
The rest of the phone, of course, is great. The extra screen size is ideal for Windows Phone, which seems to thrive in the extra real estate. The screen itself is an AMOLED with some kind of technology Nokia's calling ClearBlack. Whatever it is, it seems to work; phones with the Lumia 900's resolution (800x480) and size (4.3 inches) often seem kind of pixelly, but the Lumia looked great, with deep, dark blacks and clear lines. The largely black-and-primary-colors Windows Phone OS looked fantastic.
Lumia 900 ESPN Hub:  Dan Nosowitz

I also briefly took a look at the new ESPN app; Nokia will be preloading the ESPN "hub" on the Lumia 900. Hubs are kind of large-scale apps in Windows Phone, with a whole bunch of different sections and elements. The ESPN hub looks really great, despite being in some sort of pre-release state. It's got some nice social elements for finding sports chatter online, and it sorts by sport and then by team so you can get all the latest details on the team you follow. You can also buy tickets and get directed to the stadium, right from that app. All of those latter features are exclusive to the Lumia 900.
My only real concern is that it has the exact same camera sensor as the Lumia 800, which was disappointing, But software can fix a lot of problems in a phone camera, so it's possible they've made some tweaks.
I'm pretty excited about this phone--it's basically a bigger version of the Lumia 800 that works on an American LTE network, so it's got every opportunity to be one of the best phones in the country. It'll be released "in the coming months."

Scientists Build a Data Storage Device Out of Salmon DNA

It’s good smoked, straight up on the grill with a little lemon and butter, or rolled into sushi. And now, thanks to researchers at Taiwan’s Tsing Hua University and the Karlsruhe Institute of Technology in Germany, salmon is also good sandwiched between two electrodes. Using silver nanoparticles, a couple of electrodes, and a thin layer of salmon DNA, those researchers have developed a “write-once-read-many-times” (WORM) data-storage device that they think could eventually lead to a replacement for silicon.
Their device works based on how silver atoms behave inside a thin film of salmon DNA. Shine a UV light on such a system, and the silver atoms will bunch into nanoparticles within the DNA film. Add electrodes to both sides of the film, and you’ve got an optical data storage device.

And here’s how it works: when there’s no (or little) charge passing through the device, only low (or no) current is allowed to travel through the device (which makes sense). That creates the device's “off” position. If you slowly increase the voltage however, the device is unable to hold a higher charge. That is, until you reach a certain voltage threshold (about 2.6 volts), at which point the device suddenly switches to high conductivity with good retention of that state.
That switching ability above a certain voltage threshold creates two distinct “off” and “on” states that can be used to store data like any other optical data device. And the changes in conductivity are basically irreversible, meaning once a device has been switched, it stays in that conductive state (either on or off). That means you should be able to write something into a DNA-based data storage and then retrieve that info later.

The World’s First "Nano-Ear" Can Listen to the Songs of Bacteria



Hearing sounds smaller than any we've ever heard before

German researchers have turned an optical tweezer device into the world’s first “nano-ear”capable of detecting sounds six orders of magnitude below the threshold of human hearing. Using an optically trapped gold nanoparticle as their listening device, the team says they can now detect sounds made at the bacterial level or use their device to tune (or perhaps to test?) the minuscule MEMS machines of the future.
The nano-ear is pretty simple, considering that it relies on technology that has been laying around in the lab for decades now. Optical tweezers are laser devices that use light to trap or manipulate a small particle in a particular point in space by drawing the particle to the most intense point in the laser beam’s electric field. By trapping a gold nanoparticle in just such a optical trap and measuring the influence of various sound waves on that particle, the found that they can “listen” to very small vibrations.

That means sound analysis at extremely low levels. The gold nanoparticle itself is just 60 nanometers (that’s 60 billionths of a meter, or roughly a thousand times smaller than a human hair), which makes it pretty sensitive to very small forces. The researchers used both a “loud” source--a tungsten needle glued to a speaker that vibrates at roughly 300 Hz--and a second source made up of bunches of other gold nanoparticles heated by a second laser to vibrate at just 20 Hz.
The nano-ear could hear them both loud and clear. The sound waves nudge the trapped gold nanoparticle in the same direction that the waves are propagating, allowing for precise measurement of the sound itself based on the particle’s motion. Experiments showed the nano-ear could detect vibrations down to about -60 decibels--or six orders of magnitude lower than human hears can. That means the device could be used to identify microorganisms or processes at the microscopic level by their sound signatures, or to help design and tune microelectrical mechanical systems.
