Do you think that the weight of applications and files is only measured in megabytes? Many will be surprised to learn that the iPad is heavier as downloading games, programs, or multimedia content. Paradoxical phenomenon described teacher of computer science at the University of Berkeley, John D. Kubiatovich.
The secret to weight gain transistors iPad is flash memory. On an electronic device, they are distinguished either 1 or 0 (electrons or holes). The more data on the tablet, the more charged particles will be trapped. Thus, additional weight depending on the amount of data stored on the device.
According to calculations of the professor, the differences in weight between the empty and filled 4GB iPad insignificant, but they are. Last heavier than about 10 -18 grams. For the 64-gigabyte version of the weight increases by about 12 times.
Another fun fact on battery iPad: fully discharged tablet weighs a little less than 100% charged.But if your hands get tired after long use of a fully charged gadget - most likely it is the fruit of the imagination. The difference can only define the most sensitive balance with a precision of 10 -9 changes.
