8-inch floppy disk, inserted in drive, (3½-inch floppy diskette, in front, shown for scale) 3½-inch, high-density floppy diskettes with adhesive labels affixed The first commercial floppy disks, developed in the late 1960s, were 8 inches (203.2 mm) in diameter; [4] [5] they became commercially available in 1971 as a component of IBM products and both drives and disks were then sold ...
Wegerer's supposed photos of two of the stones are too low in resolution to show the hieroglyphs and look to be bì discs. [6] Bì are round jade discs with holes in their centers. When buried in the earth, the minerals change them to be multi-colored. Bì have been dated to 3000 BCE and were common in what is now Shaanxi.
Each side of the disk had 46 tracks, and the number of sectors per track varies from 15 to 22. This results in 851 sectors per side, or a total capacity of 871,424 bytes. [ 5 ] The Lisa Hardware Manual doesn't explicitly state the total number of sectors, but page 173 states that there are 4 tracks of 22 sectors, 7x21, 6x20, 6x19, 6x18, 6x17 ...

Scrolling on social media is also a way to "disassociate" and give the brain a rest after a long day, Bobinet said. This is an "avoidance behavior," which the habenula controls.
All images of the known 71 disks, including those of the photographic disk, were rendered in elongated form to compensate the distortion of the projection. The projector was related to other projecting phenakistiscopes and used some slotted metal shutter discs that were interchangeable for different picture disks or different effects on the screen.
In the accompanying illustration, A represents a circular disk of 10 units diameter at rest in an inertial reference frame. The circumference of the disk is times the diameter, and the illustration shows 31.4 rulers laid out along the circumference. B represents a circular disk of 10 units diameter that is spinning rapidly. According to a non ...
Disregarding symmetries, there are 10 different positions on a board, and each of these is given a value for each of the three possibilities: black disk, white disk and empty. A more sophisticated approach is to have different values for each position during the different stages of the game; e.g. corners are more important in the opening and ...
