Flying windmills!

“Energy”, don’t know how many times we use this word, but we surely use energy everyday. By now, we know what renewable energy sources are( if not go ahead and click here Renewable).

One of the most effective renewable sources of energy is wind energy, till now we have seen only the windmills on the ground producing energy. But, here are the new ones that are situated above the ground so called “Flying Windmills”.

So, what is the reason to put the windmills above the ground? Well… Higher altitudes offer upto five times stronger winds that are also consistent.

This thing flies with the help of helium filled shell. The airborne wind turbine will be held steady by making use of strong tethers which will also transfer the electricity generated to ground. And Flying windmills are actually tested!

Ben Glass, is the one who came with this idea. Learn more about these flying windmills from the video below.

Turn your table top into an Android tablet!!


Ever thought of turning your table top into a touch screen? well… This gadget does just that. Lazertouch is a new, small projector that can turn any table top or even a wall into an Android tablet. This gadget showed up in INDIEGOGO. To detect touches, Lazertouch puts out a laser that is parallel with the surface. The projector is portable, and has  13,600mAh battery inside.

This can be used just like any android tablet.. Watch out the video, that looks really good..

 

GLOWING PLANTS!

Ever thought of trees glowing? Maybe now you should.. So, technical name for these type of plants is Bioluminescent plant. The first bioluminescent plant was made in 1986, with the addition of firefly luciferine.

There are a few species like jelly fish, fireflies etc.. On our planet that can glow. To make the glowing plants, the team first uses the Genome Compiler software to identify a plant’s DNA. The software then custom prints the sequence and then inserted into a plant.

The main sequence responsible for making the plant glow is known as luciferase (it can also be found in fireflies). Unlike the previously made Bioluminescent plants, where the plants aren’t so bright,  now scientists have been able to get the gene to recycle itself and make the plant especially bright.

Scientists say that the intensity of the light emitted by these Bioluminescent plants isn’t that high to replace streetlights. Hopefully someday we replace our street lights and table lamps with Bioluminescent plants.

Live forever “Frozen”(Cryonics)!

We have seen so many weird to the weirdest things in science, but I think nothing can be so weird than this. Basically cryogenics is the study of something in cold, but CRYONICS on the other hand is the study of some living thing kept in cold.

Cryonics is actually a process of preserving the human body in an extremely low temperatures, hoping that some day, science could be able to bring them back to life ( Technically called reanimation). “Hoping??” Yeah, this isn’t perfect yet, as of now scientists have only found the way to preserve the human body, but science has yet to improve further to bring the preserved human back to life!

You may ask, why on earth people want to live frozen forever? Well… The people with un-curable diseases hoping that science one day finds a cure or people just curious about future may end up preserving themselves through cryonics.

Now, let’s see what happens here rather how it happens. Once the person is dead, the cryonics team inject some antifreeze to protect the tissues from freezing because. The main problem here is our cells are full of water and when we freeze the body cells may freeze, when liquid freezes they expand so, there is a chance of breaking the cell membrane in this process. Then the body is cooled rapidly and finally kept in a liquid nitrogen container for too long.

It may take a few years or even decades to find a way to reanimate the human body (bringing the human back to life).

Science fiction is no more a fiction!!

 

 

Misconceptions about tides! What really causes tides?

Many people get it wrong about the reason for gravity of moon and sun responsible for tides. Now, let me ask you something, why don’t we see tides in a lake? And why don’t we see sand and rocks levitate, Due to the Gravity of moon and sun?

Let’s see what actually cause tides. When you are in an accelerating bus( technically in an accelerating frame or non-inertial frame), what ever may be the mass of the object, they  experience force while bus turns, in a direction opposite to the turn. This force is similar to the Tidal force experienced by earth.

Here, what ever may be the mass of the object on earth, they should move out of the surface of earth. But that’s not happening here, all the objects aren’t moving out. The tidal force isn’t acting only on the moon-earth line, because if that was the case ( tidal force acting along the moon earth line), we should see the lakes, ponds, rocks, you and me raising, but we aren’t. And the tidal acceleration due to the gravity of moon along the earth moon line is 1/10,000,000th gravity of earth, so it is not possible for this tiny force to lift something on earth. But that tides are real here!!!!

Then, what is really causing tides???

Until now, we only have considered forces on the earth-moon line. Now consider the forces acting on some other points on earth, the resultant of the forces at that point, i.e., the TIDAL force at that point is observed to be radially downward. By mapping the direction of tidal force at various points on earth, it looks something like the image down below. With the image below, it is clear that, this force is not lifting or stretching but getting SQUEEZED.

From an unknown source on the internet, I have read that this phenomenon is similar to that of squeezing a pimple;);) So true.. This makes it easy to answer my above question “Why do lakes don’t have tides?”. Well… You got it, they are like small pimples, hard to blast:);). They have a smaller surface area and have tiny microscopic tides, which can’t be seen. By the way, the similar is the case with sun. The Sun is very far from earth yet with a huge mass. So,according to the position of the sun, earth and moon the bigger and smaller tides are formed!

Let me know, what you think!

What’s Encryption? And what’s Quantum Cryptography?

Encryption is simply taking some information that makes sense and scrambling it into some mess, so that no one can open it without a specified key. In reality, many websites on the internet contain some of our secret and sensitive information( like credit card info and even messages), to protect these we use Encryption.

So, how do they manage to protect our information?

Well.. The information is first turned into some other sequence or into bits, then we use something called KEY, to protect our information.

This key is like, multiplying every bit of the code with a certain prime number or something else. This makes it difficult to crack. Because, its easy to know the multiplication of two prime numbers. But, its pretty tough to tell the two prime numbers with which the number or the output bit is obtained.

And for encryption, we don’t use small primes, we actually use bigger prime numbers. It may take years to find the factors for that number by a human. But the machine(computer) created by the human is super fast and can find the key faster than you expect, of course that damn tough to do so.

Now, let’s see what “Quantum Cryptography” is?

Encryption is done purely based on mathematics. When it comes to highest level of protection, “Quantum Cryptography” comes into picture. Unlike encryption, Quantum Cryptography uses physics. In Quantum Cryptography, the information is hidden in Photons(light particles).

The key here is  a stream of photons travelling in one direction, with each of these photon particles representing a single bit of data (either a 0 or 1). All of these photons are oscillating (vibrating) in any 360-degree range across any conceivable axis, let the  oscillations be grouped into 4 particular states: UP/DOWN, LEFT/RIGHT, UPLEFT/RIGHTDOWN and UPRIGHT/LEFTDOWN.UPRIGHT/LEFTDOWN. The angle of this vibration is known as the polarization of the photon.

A polarizer is that which simplifies a filter that permits certain photons to pass through it with the same oscillation as before and lets others pass through in a changed state of oscillation.

Now, let’s see how a key is made. Let  “A” sends oscillating photos may be UP/DOWN, LEFT/RIGHT, UPLEFT/RIGHTDOWN and UPRIGHT/LEFTDOWN. The receiver “B” uses two types of polarizers ( Diagonal and Horizontal/vertical) for each photon, to polarize and ends up with an information waiting for a confirmation by the sender “A” about the polarizer “B” used, that is, Diagonal or Horizontal/vertical polarizer.

Because, a Diagonal polarizer won’t polarize a Horizontally polarized photon, that is, there is a 50% chance of 1 and 50% chance of 0. Finally once the sender “A” confirms the polarizer used for each bit, the wrongly guessed combinations are thrown out and the correct key is obtained.

Using Quantum Cryptography as of now is very tough. This was practically practised in IBM lab.

 

 

Spherical Tires!!!


Spherical tires, this may sound crazy, but they are actually awesome. Unveiled at the Geneva International Motor Show, by a company called “GOODYEAR”.

AvdRgX

These tires allows cars to move in all directions, with spherical tires, you can even slide in sideways too. Greater parking efficient, so existing parking lots can accommodate more cars without taking up any more space. But, how on this earth, they fixed the tires to the car, yet manage to make them rotate in every direction?

Well… They used magnetic levitation, rather than axles, to suspend the tires under the cars body.. Where an object is suspended above another with no other support but magnetic field.

These are 3d printed, and are smart enough to detect, whether the road is wet or dry, and functions accordingly. The coral-patterned tread also behaves like a natural sponge – responding to wet weather by softening, while stiffening in dry conditions. Here are my previous articles on 3D printing and even 4D printing 😉 (3D printing , 4D printing ).

 

 

 

 

 

Hurrah! My blog turns an year now…

Hurrah! It’s been an year now. One thing’s for sure, blogging community here is awesome. I learnt so much here. Now, my blog turns an year and I got an year of experience in blogging. This is a huge thing to me. So, I thought, why not make this article a huge one too. Before you get mad at me scrolling down and down and wondering where it ends, let me explain you something.

When I did my 100th article with 100 followers (Celebrating 100th article with 100 followers). I thought I would write my 200th article with 200 followers but, it didn’t happen now. This is my 153rd article with 210 followers;);) The funny thing is I got the followers count, as I said before  bloggers here are really awesome, but I didn’t reach my articles count;);) It’s pretty genuine though, you don’t want to read junk and I don’t want to write articles to just satisfy the count.

Moving on, as you scroll down, hopefully you find some really interesting articles. And there are so many of them. Trust me you won’t be disappointed because, all my favourite articles are listed below. The good thing is, almost all of my articles are listed. Favourites till my 100th were listed in one article and from 100th to this particular article are listed below. So, this is an eye feasting article, atleast to me;)

If you have read and still remember my 100th article you might have noticed that, a few dialogs are similar right? Yeah! In case you don’t reach the end of this article reading and scrolling, let me tell you something. Thank you so much for making this happen, thank you for your support and thanks for your suggestions. Appreciate it!

40 years of Apple Inc.

A big visionary with a great team, that is all it takes. On this day in 1976, Apple was found. And they never stopped surprising us with new tech.

Visual history of iOS!“, “Quotes of Steve Jobs”

Here’s a sneak peek on what Apple Inc. did in 40 years.

Thoughts of Walt Mossberg of Verge on Apple Inc.

 

Though this was too small post, yet worth getting inspired. I thought it’s cool to know that, a company which started in a small garage now worth almost a 500 billion dollars! And one of the most trusted, innovative and loved companies ever found.

Happy Birthday Apple Inc.

Epic moment in science( Discovery of Gravitational Waves)

For so long, scientists were trying hard to find the evidence for Gravitational waves, predicted by Einstein over a 100 years ago, in his “Theory of Relativity”. Finally, scientists at LIGO( Laser Interferometer Gravitational Waves Observatory) detected Gravitational Waves.

Scientists estimate, about 1.3 billion years ago, two black holes  collided at half the speed of light. Which resulted in Gravitational waves. Detector at LIGO detected these waves.

LIGO has two identical detectors, one located in Livingston, Louisiana, the other in Hanford, Washington. These Detectors can detect even very little vibrations from Gravitational Waves.

Learn more about gravitational waves here”Gravitational Waves“. Also about the origin of our universe, cosmic inflation here” Origin of our universe“.

This discovery changes our perspective on how we see the Universe.
