(well, those with a calculator and too much free time, anyway 🙂
Just noticed something
have a look at the multiples of 125²/7² (15625/49), especially 10x, 20x, 30x… as the phenomenon is a little more noticeable.
Except for the first two, each two digits (allowing for 100’s carryovers on occasion) is a double of the previous.
How cool is that? Found it while trying to figure out how far bullets fired into the air can travel, after reading an oddball news report.
