  • A single point of data rarely answers the question unless you’re looking for absolutes. “Will zipping 10 files individually be smaller than zipping them into a single file?” Sure, easy enough to do it once. Now, what kind of data are we talking about? How big, and how random, is the data in those files? Does it get better with more files, or is the a sweet spot where it’s better, but it’s worse if you use too few files, or too many? I don’t think you could test for those scenarios very quickly, and they all fall under the original question. OTOH, someone who has studied the subject could probably give you an answer easily enough in just a few minutes. Or he could have tried a web search and find the answer, which pretty much comes down to, “It depends which compression system you use.”




  • This is kind of wrong, and is a common conflation with respect to science. First, scientists do talk about things that cant be proven, string theory being just one of them. It’s an idea of the physical world that cant be proven. If we have a way to actually test a hypothesis of string theory, it will get more attention. But if you don’t have people thinking about these things, we won’t have better models for describing the universe, such as relativity. Similarly, science can’t prove a negative. Science will never tell you God doesn’t exist or can’t exist, only that we have no proof that God exists and that we have no model where he could. But our knowledge has been less complete before, and our models have been updated as knowledge is gained.

    And much of philosophy has no basis in the physical world, but this doesn’t mean it isn’t worth thinking about.
