Not at all complicated. A bike is made so that the front wheel will turn in the same direction as the bike is leaned. This has a simple stabilising effect. Bike leans right, front wheel turns right, increased centrifugal force from the shar

If you lean your body to the left the bike reacts by leaning to the right. Your body can only move by pushing the bike in the opposite direction.

I think it's fine. It's a measure of gas flow I can relate to.

When you scale a figure, say by doubling all distances, the area quadruples. Scale by factor k and the area goes up by a factor k^2. So if the area proportion between the triangle and the square is T:S, and we scale both figures by the same

Really? Sounds like a major complication to the cable manufacturing process. Wouldn't all those holes in the shielding hose degrade cable specs? All for not having to drill a hole for the eventual connecting tap.

How did we make a similar adaptor in the 80'ies with a microprocessor running 2 MHz? Fortunately the PLA was invented. A few bits of memory and a little programmable logic. Enough to synchronize to the, in this case 2.35 MHz, Mancheste
