> math get's really counterintuitive to grasp
People always say that about speed of light stuff, but I don’t get it. Do you have any more examples of counterintuitive math?
Because what you’re describing is basically the equivalent to compound interest in finance. (e.g. investing $100 at 10% interest over 10 years results in $260)
- jeanlucas 7d agoOne million seconds is 11 days, a billion seconds is 31 years.
- rrr_oh_man 7d agoThanks! But same here imho: 1,000 seconds = ~0.01 days (~17 min) 1,000,000 seconds = ~11.57 days (~12 days) 1,000,000,000 seconds = ~11,574.07 days (~32 years) 1,000,000,000,000 seconds = ~11,574,074.07 days (~32k years) It all seems quite logical once you put everything into the same unit, I think. Maybe it's just our human calendar/time unit rollercoaster (60*60*24*30*12) that's playing tricks on us here.
- jeanlucas 7d agoOf course it is logical, we are not discussing the math. But it isn't intuitive, you're not used to numbers that big or that grow that fast. Few things go from a million to a billion, especially when related to time.
- mathgeek 7d agoIt’s the units that make it seem unintuitive. 12 days is roughly 0.032 years, and 17 minutes is likewise 0.000032 years. It’s relative to how we were taught to view smaller lengths of time. Of course you could argue measuring time by the rotation of heavenly bodies is more intuitive than counting on your fingers for the hours in a day and days in a lunar cycle.
- saberience 7d agoGoing from a million to a billion isn't some special relationship. It's just * 1000. It's the same as going 11000 or 101000. I find it frustrating that people seem to think that someone going from 1M to 1B is somehow different to other numerical operations. It's not. It's 1000 times bigger, it's not a huge deal.
- jeanlucas 7d agoAnd any exponential growth is also a multiplication, it's not a big deal, just giving example on what they asked before. Somehow people are interpreting this as some kind of math trick. It's not a trick, our brains are not wire to deal with numbers growing quickly, but we do understand the math.
- RHSman2 7d agoOnly abstractly. If you are living in the process, it is hard and very few people live that.
- lightedman 6d agoWhich process, though? Every human alive easily went from millions of cells to billions of cells to trillions of cells.
- MathMonkeyMan 7d agoThe proper time (that is, the time the traveler measures on a clock) goes to zero very quickly towards the end. Even with both axes plotted logarithmically, it's just a sudden drop at the end towards light speed. - [pic](https://home.davidgoffredo.com/hackernews/proper-time-one-light-year.png https://home.davidgoffredo.com/hackernews/proper-time-one-li...) - [plot](https://home.davidgoffredo.com/hackernews/proper-time-one-light-year.plt https://home.davidgoffredo.com/hackernews/proper-time-one-li...)
- rrr_oh_man 7d agoLinks seem to be broken?
- MathMonkeyMan 7d agoNo, but IPv6 only these days. I never set up dynamic DNS.
- rrr_oh_man 7d agoCan you explain for dummies how... a normal person with a normal web browser should access this?
- tcfhgj 7d agoEnable ipv6
- Sohcahtoa82 6d agoNot an option for me. I have a residential ISP that gives me symmetrical gigabit fiber, but has no support for IPv6.
- chungy 7d agoHave an IPv6 connection.
