Don’t forget to reload or refresh typically. The programmer might after all just simulate the whole universe (or multiverse?) but that again would not work for the simulation argument. Drawback is, on this case it must be doable to encode a whole universe in part of one other universe, and parts of the simulation would attempt to run their very own simulation, and so forth. This has the effect of attempting to breed the laws on shorter and shorter distance scales. That, too, isn’t appropriate with what we know about the legal guidelines of nature. Sorry.

IBM introduced the first magnetic disk , the RAMAC , in 1955; it held 5 megabytes and rented for $3,200 per month. Magnetic disks are platters coated with iron oxide, like tape and drums. An arm with a tiny wire coil, the read/write (R/W) head, moves radially over the disk, which is divided into concentric tracks composed of small arcs, or sectors, of knowledge. Magnetized areas of the disk generate small currents in the coil because it passes, thereby permitting it to read” a sector; similarly, a small present in the coil will induce a neighborhood magnetic change in the disk, thereby writing” to a sector. The disk rotates quickly (as much as 15,000 rotations per minute), and so the R/W head can rapidly attain any sector on the … Read More
