What is Magnus Effect ? What's its Use Beside Games.

If you love science, then you will love this article on Magnus Effect. It's amazing how can a basket ball fly in the air with the help of a backspin ? 

All thanks to Magnus Effect. 

 In the video, it shown what happens when you drop a basket ball from a 126 feet heigh dam in Australia. It falls on the ground straight (more or less) but when a you add a spinning on the basket ball, it fall after taking a fly horizontally in another direction.

Why ??

Because, Magnus Effect... An effect when applied on a rotatory object whether it's circle or cylindrical it flies, in the air.

As video says, "As the basketball picks up speed, air on the front side of the ball is going the same direction as its spin, and therefore it gets dragged along with the ball and deflected back. Air on the other side is moving opposite to the ball’s spin, so the flow separates from the ball instead of getting deflected. The result is that the ball pushes the air one way so the air applies and equal force on the ball the other way."

Magnus effect is widely used in games like soccer, football and etc. But what is real use ??

In the video, you'll also see a Rotor Ship, Flettner Rotor. Flettner Rotor uses the same concept of Magnus Effect. It has two cylinders, which spins and pushes the ship forward.

It's also used in airplanes also. So we're seeing at the future, with some promising Magnus Effect Applications.

An amazing thought becoming reality : Project Jacquard.

Hi Everyone..!!

What you will do ,if   suppose  you are busy and your phone is ringing quite far away from you  & you want to reject the call or pick it up  or if  you want to increase the volume while watching movie from your phone placed at some distance.  How will you do it ??
   Your answer would be , that obviously you will go and pick the call or reject the call as you do always. But i would say that soon  operating your phone manually, would just be an option for you.
 Getting restless to know how..?? I will be giving you answer for this later in this post.  

  Actually, i'm going to introduce you a little  about the "Project Jacquard ", that has been announced by the Google this year at its annual developer conference  'I/O ' , held at San Francisco(United States).This is a very unique concept , founded by  Ivan Poupyrev ,one of the team members of Google's ATAP team. The project is going to innovate the product of textile industry, that is our clothes.

  This project involves manufacturing of a conductive yarn , that is done by braiding together the metal alloys and the fibers of some fabric. This  conductive yarn helps to create a kind of fabric panels ( a touch sensitive panel same as screen of your smart phones) which act as an interface to interact with  a digital device such as a smart phones or tablets. We can operate our smart devices using their controls with the help of this conductive yarn.

  What happens is that when we touches a grid made up conductive threads , it automatically sends a signal to a chip which may  be located somewhere in our clothes. That chip then translates those signals into  controls for the devices such as smart phones.
    Now i will answer the question i've asked above .Using this technology , you can pick a call or increase volume  of your phone without even touching it.What you need to do is just rub your sleevs....;)

   The company Google wants to make this project scalable , along with making the products trendy as well as fashionable.Google wants to make it available for all using existing clothing brands.The name Jacquard is chosen for this project , after the name of  Joseph Marie Jacquard, the inventor of Jacquard weaving process.

   One of the major advantage is that the conductive metal alloys can be woven into any type of fabric using normal industrial looms. We can also choose desired color of yarn. Also the yarn seems so natural though very strong in nature. The chip i've talked about that receives signals is very compact in size equal to that of a blazer's button.It's embedded with the circuits & connectors.

 

Mr. Poupyrev  showcased a prototype , that is a blazer at I/O 2015. In 2016 Google can launch its products based on project Jacquard in collaboration with Levi Strauss & Co. This company will take the charge of manufacturing the garments only. Technically it will be handled by Google.
   The development of the  platform or environment for Jacquard  is under progress, according to the Jacquard Website.

In the end , i would say that after smart phones, smart cars, smart homes, smart gadgets, smart kitchens.......we will all have smart clothes. Thanks Google.

Google I/O Extended 2015

Hii Everyone,
This time i am sharing with you all an opportunity to be a part of a mega event . I am talking about I/O Extended 2015 that is being hosted by GDG Jalandhar, in collaboration with GSA's and GBG's of north region, at Chandigarh on 28thMay,2015.
Google I/O is an annual developer conference held by Google in San Francisco, California. Google I/O is a highly technical developers conference. Focuses on building web, mobile, and enterprise applications.

Google I/O Extended  events include live streamed sessions, local developer demos,hackathon and more.This is really going to be a great opportunity for the students and tech enthusiast to witness newest and exciting technologies.

Venue : Chitkara International School, Sector 25, Chandigarh ( Punjab )
Register yourself here  I/O Extended 2015 CHANDIGARH.

Note: No registration fee and Swags will be given to all attendees.
   

Big bang with the launch of Google's Cloud Bigtable.

 Yeah, its about  Google's recently launched database service that is  highly efficient ,full-fledged database ever, as its performance is enhanced and has become extremely scalable No SQL database.
This service is easily accessible through industry standard open source, that is Apache HBase API.So, this service is offering a tremendous opportunity for the concerned  geeks of  Enterprise industry who handles the databases by working for hours to manage the complex and  huge amount of data.

   This technology offered by Google , the Google Cloud Bigtable  proves its excellence by its extra ordinary capabilities of handling huge volumes of complex data at quite fast pace. Its capabilties of  handling complex analytic procedures,  large ingestion of data ,and also data-heavy serving workloads are at their  best.
   The compatibility of Cloud Bigtable with Google's Bigtable data storage system(distributed system for dealing with structured data) with Apache Hbase API , is the main blend of Google's major technologies . It aslo comes under the Google's  Bigtable Project ,that is already handling many  projects at Google Store including Web indexing, Google Earth and Google Finance.Such applications lay demands in terms of dta size and latency requirements.But Bigtable  has provided a flexible and fast processing solutions to all these requirements.
  It's an ideal service for enterprising industries and data-driven organizations that need to handle volumes of data, including business oriented organizations  in the financial services, in  AdTech, also in  biomedical industries and  telecommunication industries.So, now time to talk about the special benefits:

• Perfomance scale: Minimum latency  (Just unit digit millisecond latency).
• Security : In this a kind of  replicated storage schema or procedure is used and all data is encrypted twice, both in-flight and at rest.
• Cost: The  total cost of  having   Bigtable is almost less than half the cost of its direct companions.
• Open Source Interface: Because it is accessed using Apache HBase.
• Simplicity:Creation or reconfiguration  the cluster is achieved through a simple user interface and can be done in less than 10 sec. 
• and many more.

For now, this  new service is available for developers only that is in beta form,  but isn’t offering an SLA or technical support yet.
