  • As far as I understand, the latency is improved by the different speed of light of the DNANF: In conventional fibres, it is limited by the refractive index of glass, reducing the speed of light in it to ~70% of speed of light in vaccum (Wikipedia on this topic). In this new concept, the light travels 45% faster.

    I think, the lower loss (lower attenuation) is “just” an enabler for long distances: You can easily have hundreds of km without repeaters – and repeaters for DNANF cables would add latency. If they can get attenuation improved a bit more, they may even be able to cross the Atlantic ocean without repeaters.

    As a nice side effect, those DNANF cables have very little dispersion, so you can get rid of compensating for that, which will reduce latency too.

    How good of a conductor wood is depends on its state. If it is very dry and not salty, this should be safe (although he could have taken the piece of wood more at the end to increase the distance between him and the fence and the length=isolation through the piece of wood). If it is wet and salty, it might be dangerous.







  • Your comment is incorrect in many different ways.

    Butter is fat and some sugar and protein.

    No. The butter in my fridge has almost no sugar (0.6g in 100g) and almost no protein (0.7 g in 100g).

    Pasta is mostly carbs.

    For comparison: The pasta I have at home have more sugar (most have roughly 3g in 100g) and way more protein (12g in 100g).

    they all become calories, and if you eat more calories than you burn, they will be stored as fat.

    Are you sure you’re not simplifying too much?

    Also, “just” eating less or more calories is not that easy if you ignore the side-effects. Carbohydrates will make you hungry very soon unless mixed (or eaten after) fibers, fat and protein. Which you should do anyways for health reasons.
