iPhone
The iPhone operates in a realm where speed is measured not in kilometres per hour, but in gigabits per second. The device's A-series processors execute approximately 15.8 trillion operations per second, whilst 5G connectivity enables theoretical download speeds of 10 gigabits per second. A photograph can traverse the globe in milliseconds; a video call connects London to Tokyo instantaneously.
Yet there is a curious paradox here. For all its computational velocity, the iPhone itself remains stationary unless carried by a human—or, indeed, by a train. Its speed is purely informational, a kind of ghost velocity that moves nothing physical whatsoever.
Train
The train's relationship with speed is altogether more visceral. The Shanghai Maglev achieves 431 kilometres per hour, whilst France's TGV has recorded speeds exceeding 574.8 km/h. High-speed rail networks in Japan, China, and Europe routinely transport millions at velocities that would have seemed supernatural to our great-grandparents.
More significantly, the train moves not merely data but matter itself—tonnes of steel, glass, and human flesh hurtling through space. This is physical speed with genuine momentum, the kind that can be felt in the pit of one's stomach as the platform recedes into the distance.
