Long DescriptionThe delightful episode ''Tomorrow Is Yesterday'' is a time-travel story with an infectious blend of suspense and humor. After dropping into a black hole, the Enterprise ends up orbiting the Earth in the late 1960s and is spotted by U.S. Air Force captain Christopher (Roger Perry), who happens to be flying by in his jet. Inadvertently giving poor Christopher an unwanted glimpse into the future, and wrecking his jet with an overpowering tractor beam, Capt. Kirk (William Shatner), not having a good day, beams him aboard the Federation starship. The collision of sensibilities and reference points between characters born several centuries apart has a fresh, urgent tone that subsequent Star Trek series have never captured (though Deep Space Nine came close with its dazzling episode ''Trials and Tribble-ations''). The problem, of course, is what to do about Christopher now that he knows what he knows, and history demands that he stay put in his own world: the pilot's unborn son, it seems, will one day make a space flight of historic importance. Terrifically entertaining and something of a precedent-setter for Star Trek IV: The Voyage Home (the theatrical feature set in contemporary San Francisco), ''Tomorrow Is Yesterday'' is Trek at its best. --Tom Keogh

QR Codes are a type of 2 dimentional (2D) barcode that are commonly used in advertising and supported by most smart phones. These compact codes can make it very easy to get digital data from print into a computer or smart phone.

Originally created for the automotive industry, these codes have exploded into use in print on business cards, in magazines and even seen on web sites. This is because of the increased access to smart phones that can easily scan these codes and transfer the data to the user.

There are a number of uses for these codes. Web links, contact information (vCard) and other useful types of information. Here is an example of a QR Code that you can scan.

Barcode QR Code

The large square patterns you see in three corners of the image are used for positioning. The smaller box you can see in the lower right portion of the image is used for alignment. Connecting the positioning blocks are a series of timing blocks which always alternate light/dark (0/1).This allows the scanning device to recognize and scan regardless of how the pattern is oriented. To make this easier to identify, here is a colored version of the same QR Code with the positioning blocks marked in red, the alignment block is marked in yellow and the timing marks are marked in green.

Barcode QR Code

There are also sections for versioning and formatting which are kept around the positioning blocks. In the image below, the formatting blocks are marked in red and the versioning blocks are marked in yellow.

Barcode QR Code

The remaining blocks make up the content information and associated error correction data. As the amount of data grows, more alignment markers are inserted into the image. It is important to print the image in a large enough size. If the image is too small or too dense, scanners could have trouble reading the data back.

If you would like to create your own QR Codes, there are several web sites that let you do this. We actually have our own QR Code generator on this site where you can create your very own QR Codes for any use you like and it is totally FREE!
