  • The harder thing to convey is the full dimensionality of it. With the rubber sheet (or trampoline) you can show a small ball orbiting around a larger one but only in a single plane (around the “equator” of the large ball). However in reality you can orbit in any direction you like and many satellites actually orbit over the poles. Trying to show that with a small model seems extremely difficult!

    Furthermore, most children are raised on the idea that gravity is pulling them down. They intuitively understand the idea that when they climb a ladder and drop a ball from the top, the earth pulls the ball down. General relativity tells us that this is not happening at all! That there us nothing pulling us down whatsoever. I have yet to see anyone provide a lay person GR explanation for the ladder problem.



  • Yes, the key here is to not let people push you around with this statement. Sometimes people like to say this when they implicitly mean “I am comfortable with X, therefore you should be comfortable with X.” This is not a genuine attempt to help you!

    However, stepping outside of your comfort zone can also mean trying new things you were initially reluctant to try or hadn’t thought to try. Here you have the opportunity to discover some truly great new hobbies/interests that can enrich your life!



  • Oh because that incorrect analogy is the most common “lay person” analogy for describing gravitational curvature of spacetime. The most common reply from children is that it’s the earth’s gravity pulling down on the bowling ball so that the trampoline demonstration wouldn’t work in space.

    Also the trampoline analogy doesn’t show us how gravitational lensing works, nor does it even touch how different gravitational reference frames affect the passage of time (GR generalizes special relativity, after all).




  • I think you’re right. However I think this could also be compensated for. The trick would be to tweak the number of copies of each scroll in the deck. Then really powerful scrolls like rage or lullaby or retribution could be made relatively uncommon.

    I suggested in another reply the idea of having a “hand” of scrolls that the book draws into and shuffles after emptying. What if the hand size scales with upgrades to the book? Start at 1 (which is basically identical to current behaviour) and scale up to a hand of 5 at max upgrade?

    Anyway my goal here is not to make the book more powerful than it already is. The goal is to make it more strategic than “read all of the charges during a critical moment and hope for the best” without losing the flavour of randomness and chaos.




  • I was thinking about how to alleviate your issue partially. What if instead of going through the entire library of scrolls every time, the book would draw a “hand” of say 5 scrolls that you’d use up and then it would shuffle and draw 5 more? If the book told you which 5 scrolls were in the hand then you’d have the ability to plan what to do with them. For example, having retribution and rage and lullaby in your hand would be a very powerful combo to use against the Dwarf King. Much better than ID and remove curse (especially if you don’t have anything left to ID).


  • The issue with fighting climate change is that it’s a game of chicken between all the countries. If the UK goes all out and eliminates all emissions (at the cost of some portion of its economy) but every other country stays the course, then climate change just carries on and the UK’s sacrifice is in vain.

    Similarly, if every other country in the world buckles down and stops climate change but the UK carries on, the UK ends up ahead. This means there is a double disincentive to cooperate on climate change.

    Canada is going through this issue right now. The Liberal government has gone forward with carbon taxes and now these policies have become deeply unpopular. The Liberal party is now staring down the barrel of a potentially historic defeat in the upcoming election next year.
