How many megapixels does the human eye have???

you see things one way, and your camera sees things differently.
So, what is the resolution of the human eye, at which a camera would be able to truly capture an image the way the eye sees it?

The answer is 576MP, the technical breakdown is as follows:

Consider a view in front of you that is 90 degrees by 90 degrees, like looking through an open window at a scene. The number of pixels would be 90 degrees * 60 arc-minutes/degree * 1/0.3 * 90 * 60 * 1/0.3 = 324,000,000 pixels (324 megapixels).

At any one moment, you actually do not perceive that many pixels, but your eye moves around the scene to see all the detail you want. But the human eye really sees a larger field of view, close to 180 degrees. Let’s be conservative and use 120 degrees for the field of view.

Then we would see 120 * 120 * 60 * 60 / (0.3 * 0.3) = 576 megapixels.

The full angle of human vision would require even more megapixels. This kind of image detail requires A large format camera to record.

Therefore, once our cameras reach 576MP, the pictures you take with your camera will look exactly the same as you see them.

Just be patient, its coming out, soon.. In the next millennium.. Maybe.

Wireless charging is any of several methods of charging batteries without the use of cables or device- specific AC adaptors. Wireless charging can be used for a wide variety of devices including cell phones, laptop computers and MP3 players as well as larger objects, such as robots and electric cars. There are three methods of wireless charging:
>inductive charging
>radio charging and
>resonance charging.

Inductive charging is used for charging mid-sized items such as cell phones, MP3 players and PDAs. In inductive charging, an adapter equipped with contact points is attached to the device's back plate. When the device requires a charge, it is placed on a conductive charging pad, which is plugged into a socket.

Radio charging is used for charging items with small
batteries and low power requirements, such as
watches, hearing aids, medical implants, cell phones, MP3 players and
wireless keyboard and mice. Radio waves are already in use to transmit and receive cellular telephone, television, radio and Wi-Fi signals. Wireless radio charging works similarly. A transmitter,
plugged into a socket, generates radio waves. When the receiver attached to the device is set to the same frequency as the transmitter, it will charge the device's battery.

Resonance charging is used for items that require large amounts of power, such as an electric car, robot, vacuum cleaner or laptop computer. In resonance charging, a copper coil attached to a power source is the sending unit. Another coil, attached to the device to be charged, is the receiver. Both coils are tuned to the same electromagnetic frequency, which makes it possible for energy to be transferred from one to the other.The method works over short distances (3-5 meters).

The idea of wireless power transmission is not new. In 1899, Nikola Tesla wirelessly transmitted 100 million volts of electricity 26 miles to light 200 bulbs and run an electric motor. However, at that time direct current ( DC, which is the wired method) and alternating current (AC) were competing technologies. DC, backed strenuously by Thomas Edison, emerged the winner.

Understand the PAN (Permanent Account Number)

                                                                                                                                                                                   

PAN is a 10 digit alpha numeric number, where the first 5 characters are letters, the next 4 numbers and the last one a letter again. These 10 characters can be divided in five parts as can be seen below. The meaning of each number has been explained further.
1. First three characters are alphabetic series running from AAA to ZZZ
2. Fourth character of PAN represents the status of the PAN holder.
• C — Company
• P — Person
• H — HUF(Hindu Undivided Family)
• F — Firm
• A — Association of Persons (AOP)
• T — AOP (Trust)
• B — Body of Individuals (BOI)
• L — Local Authority
• J — Artificial Juridical Person
• G — Government
3. Fifth character represents first character of the PAN holder’s last name/surname.
4. Next four characters are sequential number running from 0001 to 9999.
5. Last character in the PAN is an alphabetic check digit.
Nowadays, the DOI (Date of Issue) of PAN card is mentioned at the right (vertical) hand side of the photo on the PAN card. .........!

INSTALL TURBO C ON 64 BIT OPERATING SYSTEM

HOW TO INSTALL TURBO C ON 64 BIT OPERATING SYSTEM? IT IS VERY EASY FOLOW TTHE GIVEN STEPS

1. Install the software DOSBox version 0.74
2. Create a folder,for example "Turbo" (C:\Turbo\)
3. Download and extract TC into the Turbo folder (c:\Turbo\):
4. Run the DOSBox 0.74 from the icon located on the desktop:
5. Type the following commands at the command prompt [Z]: mount d c:\Turbo\ [The folder TC is present inside the folder Turbo]
Now you should get a message which says: Drive D is mounted as a local directory c:\Turbo\
6. Type d: to shift to d:
7. Next follow the commands below:
cd tc
cd bin
tc or tc.exe [This starts you the Turbo C++ 3.0]
8. In the Turbo C++ goto Options>Directories> Change the source of TC to the source directory [D] ( i.e. virtual D: refers to original c:\Turbo\ . So make the path change to something like D:\TC\include and D:\TC\lib respectively )

How to start TurboC++ in the DOSBox automatically:
You can save yourself some time by having DOSBox automatically mount your folders and start TurboC++:
For DOSBox versions older then 0.74 browse into program installation folder and open the dosbox.conf file in any text editor. For version 0.73 go to Start Menu and click on “Configuration” and then “Edit Configuration“. Then scroll down to the very end, and add the lines which you want to automatically execute when DOSBox starts.
Automatically mount and start Turbo C++3.0 in DOSBox ver 0.73:
Scroll down to the very end, and add the lines:
Those commands will be executed automatically when DOSBox starts!
Please note:
Full screen: Alt and Enter
When you exit from the DosBox [precisely when u unmount the virtual drive where Turbo C++ 3.0 has been mounted] all the files you have saved or made changes in Turbo C++ 3.0 will be copied into the source directory(The directory which contains TC folder)
Don’t use shortcut keys to perform operations in TC because they might be a shortcut key for DOSBOX also . Eg : Ctrl+F9 will exit DOSBOX rather running the code .
