  1. I walked into a coffee shop one day, where some guys were having an interesting conversation, so I joined in the conversation. I got something out of it, and I gave something back. I've since returned to this coffee shop every day, met the same people, and had interesting coversations/discussions about many subjects; as long as I keep getting something out of the discussions, and my imput is welcome, I'll keep coming back. Why should I care who originally built the coffee shop, or what its intended purpose was ? Don't overthink it; it's just a discussion forum.

  2. Indeed. A pair of plumb bobs will not be parallel on Earth, but will be in an accelerating ship. In the inertial case, a plumb-bob in the no-gravity case will not point anywhere, but off-center in an orbiting space station, they will. So there are very much differences. The most basic test: Create a 3D arrangement with 4 balls (stationary relative to our small orbiting lab) arranged in a tetrahedron (in a vacuum so air currents don't move them around). The movement of the balls will show the direction of the source of gravity, or at least the axis of it.

  3. Yes sorry, I understood it as such, but I also wanted to comment on the fact on accountability which is also vulnerable in democracies. I kind of conflated the issues in my mind, sorry for the confusion. Or animals (birds, for example) or food. And considering how connected the world has become it is silly to assume that we can effectively control outbreaks, especially those with long incubation periods via border control. Unless of course you can see a way to lock borders the moment someone on the planet sneezes. I mean for Christ sake, most infections from the US came fro

  4. Well neither does the US. There are reports of at least attempts to manipulate data and one data scientist was allegedly removed for refusing to do so. But that is not the only issue. Whether you trust info from a particular region or not, global collaboration is absolutely needed to have any chance of combating outbreaks. Dictatorship are of course suspect but it does not mean that we can ignore them in the face of global threats. Again, it is based on the erroneous assumption that catastrophe somehow care for political borders. I will add that many African nations seem to be

  5. There is a formula for this, it is the same one used to find synodic periods for planets etc. (for example, how long it takes between Earth and Mars passing each other as they orbit the Sun.) The formula is T = 1/(1/p1-1/p2) Where p1 id the time it takes for one plane to complete is orbit and p2 is the time for the other planet to complete is orbit. In this case we are not given times, so we will simply give B a complete circuit walking time of 1 time unit and thus A has a complete circuit walking time of 1/2 time unit. Thus for when they are walking in the same direction

  7. For me, as someone who aligns deeply with your central point that we should learn for the sake of learning and self-improvement and strive for continuous improvement throughout our lives (kaizen), the issue is better framed in terms of the system itself. Those who are honest and work hard are not receiving the same benefits from the system as they did in the past. For too many millions of people, hard work and knowledge alone are no longer sufficient to maximize the chances of a good life and the avoidance of suffering. For many, the only way to advance sufficiently is to game the system.

  8. Looks like you need someone with an iPad. Just checked on my Android phone and the grey circle with a heart in it is there and I can choose to vote up and down. If you have an iPhone, have a look on that and if it's the same as the iPad, it's probably an Apple software issue.

  9. Lol 😁 Im on iPad. I hit the circle and no matter where I hit it, it goes green. Not that I want to down vote anyone, just curious.

  12. @CharonYThank you for your response. That's quite sad. I went to university because I wanted to learn; acquiring a degree was almost a side issue, related more to an inherent competitiveness and the possibility, if the degree was good enough, I could go on learning for longer. But that was against a backdrop where tuition fees were paid by the state and, because of the meagre financial status of my parents, I recieved a full grant (not a loan). The only person I would have been cheating, by cheating, would have been myself. I have difficulty getting my head around the concept of cheating.

  13. As @John Cuthber delicately suggests in his preceding post, the meaning of your post is not at all clear. I think what follows is what you meant: Rather than looking directly at theist versus atheist, lets look at attitudes generated by theism versus attitudes generated by atheism. When we do this we may find fewer differences than imagined. It may even be the case that atheists have attitudes and behaviours not unlike those of a theist, because such attitudes and behaviours arise from the basic character of the human mind, not from the professed atheism or theism. Does that match yo

  14. If the acceleration was large enough, and the rocket able to withstand the forces involved, then you could make this happen in principle, since the air in the cabin is not rigidly connected to the rocket. In practice though it is unlikely that any kind of real-world rocket would survive this kind of acceleration. But regardless, your understanding of the basic principle is correct. No, because acceleration isn’t the same as velocity. A plane may go reasonably fast at cruising altitude, but it takes time to reach that maximum velocity, so the rate of acceleration involved is comparat

  15. I have not checked literature, but my own experience would suggest that cheating might be increasing and it is also dependent on the system. In North America, studying is viewed by most students as a financial decision. Especially among medical students there is a strong incentive to achieve high grades by whatever means. Students are also better informed than they used to be. They are much less afraid of potential repercussions by their profs and have developed strategies to maximize grades with the least effort. They are also more cynical and have less qualms of finding ways to (in thei

  18. I think :- When they walk in opposite directions, A crosses B 14 times and they meet when A finishes. When they walk in the same direction, A overtakes B 4 times, and catches up again at the end.
