Comment Re:The 57% in the title is misleading. (Score 1) 182

You missed the idea behind my post. I'm talking about the 'closeness' to 100%. From a particular perspective, something that's 99.9% efficient is 10x as efficient than something that's merely 99% efficient, since the former is 0.1% from 100% whilst the latter is 1%.

That means, heat loss will be 10x greater.

However, from the perspective of brightness (rather than efficiency), you're right, 99.9% is only about 1.01x more efficient than 99%.

If you dig deeper into the math, it's a 55% improvement rather than 57%. That sounds like a trivial difference I know, but the logic is important for future comparisons. Let me explain.

Presume the new efficiency was 99% and the old efficiency was 38%. Naively, that sounds like 2.6x better. However, it's far more constructive to look at it in terms of how close it comes to 100%. So really, the formula is (100 - 38) ÷ (100 - 99) which means it's not 2.6x more efficient, but 62x more efficient. To get the percentage improvement, we add a little more to the formula: (100 - 38) ÷ (100 - 99) × 100 - 100 = 6100% improvement.

With the original numbers we calculate (100 - 38) ÷ (100 - 60) × 100 - 100 = 55% improvement.

I believe it WOULD take miles if the string was frozen and couldn't 'move' once it had been lengthened. Your answer assumes the dog can pick the string up to go under it (which is a very fair assumption to make, granted). I think you basically were right but misunderstood what he was getting at.

All of that said, I would love for you to have it 100% correct, because I fucking loathe insurance companies

The vast majority of accidents are caused by bad judgment from the driver, and to a lesser extent - poorly maintained vehicles (which will be mostly resolved when EVs are mainstream anyway). It was probably originally enforced due to potentially wrecking an innocent's car (as you decide if you want to risk things if it was just your car at stake).

Yes, okay, car insurance will still exist (contrary to my initial post), but it will be like say, buildings insurance - very low, and non-forced (people won't have to insure if they don't want to).
