Light can Bend Matter!! #Power_of_Light

Till now we have learned that matter can cause bending of light such as prisms, lenses etc. But now researchers at Michigan State University have found the reverse is also true that the light makes nano-particle ribbons twist.

Researchers first place nano-particle (billionth of a meter) ribbons in a darkened room, initially, they were flat but when the light was made incident on them they mysteriously twisted, they curled up.

How did this happen? 
The surface of the nanoparticles in this experiment was made of cadmium sulfide. They had a slightly negative electromagnetic charge in the beginning. But when photons, or particles of light, hit the nanoparticles, their energy excited electrons on the nanoparticles, causing chemical reactions that made them even more negatively charged. Since two negative charges repel each other, the nanoparticles began to repel more strongly.

It took them three and a half years to really figure out how photons of light can lead to such a remarkable change in rigid structures a thousand times bigger than molecules!!

"I didn't believe it at the beginning," said lead researcher Nicholas Kotov, an engineer at the University of Michigan. "What's happening is a layer of nanoparticles starts repulsing from the others, so it creates mechanical stress, and in order to release this stress the ribbon twists itself," says Kotov.

The outcome of this experiment can be mind-blowing like self-repairing materials, the introduction of some new technologies. 

Well, what remains is the progress and detailed study of this experiment.

Probe Sent to Pluto Was powered by Original PlayStation CPU!!

What if you got to know that your smartphones are much more powerful than the computers who landed man on Moon which became "The Giant leap for mankind". Incredible isn't it. Here's one more mind blowing fact about the space explorations of NASA.

It turns out that the Probe sent to the planet (or not a planet) Pluto back then in 2006 is powered by Original PlayStation' CPU!! It is interesting because the probe which is about to reach it's destination in 2015 is running on the CPU of PlayStation's 1994 model. The CPU itself is the MIPS R3000 CPU which was re-purposed by NASA back in 2006.

But why so old technology in this much bigger project? Actually NASA prefers relies on Old and tested technologies against the latest. Which is logically right thing to do because, you cannot sent a technician or engineer far away in space to fix if anything goes wrong. So, technology which has proved itself much more reliable has to be used even if it's that old.

It's turns out that NASA made a right choice. The probe was launched back in 2006 and its about to reach Pluto now in 2015 and it's quiet impressive for a chip which is a bit older than 2 decades.

Now you would look differently towards your PlayStation, proudly indeed.

Drive "Unlimited" on a sunny day, with 0 fuel in tank.

Want to go on a drive on a sunny day with friends/family, gotta fuel problem? The "Immortus" is a car designed to let you drive unlimited distance on a speed of 60 km/h!! with a condition of sunny day. Sounds crazy yepp... it is, but true.

The Immortus is an electric car which which charges it's battery through 7 sq. m. of solar cells which cover whole of it's bonnet top and the back except the glass surface. The Immortus is founded by Australian Aurora Solar car team which has completed some solar car race events.

The car's shape is beautiful and minimalistic which super aerodynamic design which includes covered wheel. The light weight design and shape of Immortus give maximum exposure of sun to the solar panels. 

Unlike the racer cars it is designed to be on road. With top speed of 150 km/h and reaches 0-100 km/h in mere 7 seconds. The car is two seater and has optimum luggage capacity for daily use. Even the makers say the fun is a priority and tells that it will handle like a well made sports car.

The car uses small 10 kWh lithium ion phosphate battery. It has twin DC motors which are placed upright leading to each rear wheel hub each with peak output of 20 kw and total of 40 kw. It may sound less but car is designed in such a way that it will use the most of it's power.

The feather light design of the car of 550 kg give Immortus a power-to-weight ratio and acceleration equal to the Mazda MX5. The Immortus won’t use regular road tires. It’ll use tires specifically designed for solar racers, very thin wheels with low-friction tires that prioritize low rolling resistance over grip.

The company expects the car’s small 10 kWh battery pack to be good for just under 400 km (248 mi) worth of range even at night, when there’s no solar assistance topping it up. When the sun’s out and the road’s clear, that range goes up, effectively to infinity if you stay around 60 km/h. Upping the pace to 85 km/h the range drops to about 550 km.

Next ridiculously amazing dimension of Wearable Tech: Google.

Every year Google brings something freaky and for sure awesome. This time at Google I/O there something I didn't have even seen in sci-fi movies. They are called project #Soli and project #Jacquard and they are gonna make concept of Wearables something very different.

First talking about the project Jacquard (i.e. fitted to a loom to facilitate the weaving of figured and brocaded fabrics) as the definition says it has something to with the fabric. It is dedicated for manufacturing of touch sensitive fabric.  A giant blue sheet of cloth is laid out on a table here and at various points there were either monitors or light bulbs or phones stationed next to it. There are tiny little instructions too: tap here, swipe here. The arrows on those instructions point to the touch-sensitive zones on the fabric. I'm not sure what makes it tick, but there are larger threads sewn into those zones. When you tap, or swipe, or draw, it acts precisely like a touchscreen. It turns on the music, it draws a line on a screen, it changes the color of the Hue lights. Therefore, What could be mistaken for stitching is actually a touchpad.

Next to talk about is Soli. This something like -  You wave your hand over a disk and watch the screen in front of you to display your hand's position and movement in space. Basically a type of radar. The interesting part is that the chip doing all this is less than a inch square. And what's the neat thing about Soli is that it works even when something is covering it. 

Just think of putting Jacquard and Soli next to each other maybe we don't have limited touchscreen interactions and devices. It's a pretty big deal. Thinking of possibilities of these both projects together are enormous.

We breathe the light, we breathe the music. #Sony lightbulb with built-in Bluetooth speaker.

After floating speakers, the tech giant Sony has come up with this innovative and beautiful gadget which is a LED Light bulb and a Bluetooth Speaker.

So now set a perfect mood for a date, party or dinner with just a light bulb. Sony has very elegantly put the illumination and the audiology in a sophisticate light bulb. This bright gadget has 360-lumen bulb with a 2-watt, 40 mm speaker both not interfering with each other, due it's a astute and canny design. Sony has put the speaker at the bottom end of the bulb for perfect music with a reflecting surrounding to provide light in every direction equally. And for power just screw it into a normal bulb socket.

Though the bulb comes packaged with a remote of its own, users can also download an app to control sound and light via their Bluetooth-enabled smartphones. Below, check out a promo video of the light/speaker in use.

Sony is launching the device in Japan on May 23rd with a price point of ¥23,880, or about $199. There’s no word yet on whether it will make it to the States or other markets.

Phone not Smart enough: #Light_Phone

In a world of smartphones, smart watches, smart TVs and smart homes, The Light Phone seeks to stand out by being, well, not very smart at all. While in today's world everyone is n social media weather for a professional cause or a just to remain connected to friends, family and to the world.

Here Light Phone is for giving break to a person from intense connectivity to world. The project offers basic approach to the communication that is just making necessary calls.

The beautiful little device is roughly of a size of a credit card having weight of just 39 grams and thickness of 4 mm. It's basically a GSM device with 500 min prepaid talktime that links to the user's smartphone for call forwarding. Everything is handled by a companion app, and we can store up to 10 numbers and can be accessed via speed dialing.

It uses a micro usb jack for charging and can run 20 days on a single charge which is pretty interesting and need of the hour. The other hardware which it has is LCD dot-matrix display and a touch module over the illuminated keyboard. There is also a speaker, volume rocked and a microphone. Simple and beautiful. 

In today's busy world where notifications of our smartphone makes it more hectic, the Light Phone is for making your day less hectic. It might not be smartphone itself but it still requires a smartphone to do your job. 

The Light Phone project is asking for US$200,000 on Kick starter. Assuming the funding effort is successful, a pledge of $100 will secure a single unit. The company hopes to ship handsets to backers in May 2016.

Everything Connected to Everything #Internet_of_Things.

Imagining a world where things are connected to each other. By things we mean here not only smartphones or Machines or Computers, here we mean a chair a table a pen connected to each other and everything else in a room or a house.

Seems interesting and also complicated. The thought is really fascinating. I would not say it only a thought as it's becoming reality. All the major economies and technology blocks in the world are investing in it.

What actually will be the applications of the IoT ?

Major applications of the IoT will be in the health sector. Like we will be able to monitor a old age person's heart beat and collect his/her cardiac data while sitting anywhere in the world. Even that person is sitting in New Delhi his/her relatives can get real time cardiac data while sitting in Paris.

Other major application will be in the transport. Connecting cars to traffic signals and other cars will reduce time, money and energy. Even connecting people crossing the roads and notifying them about the.

Even you see whose id sitting on your chair when your not at home. We are heading towards a "Technocratic" world where future generations will make decisions on the technological basis. As we see the concept of Utopia. Not exact Utopia but we will have control over the resources of our planet.

All of this sounds very exciting but IoT has a dark side too. As everything will be connected to everything. Everything includes Humans and animals too!! So, the concept of privacy will become meaningless in a world having IoT. Hacking attacks could be done on massive scale, online harassment and worst of all Terrorism. We all can judge on how large scale these dark things can be done.

So, we need to be much careful in order to have a safe and prosperous future of mankind and this planet.
