Problem #7:
2. B 2020 Nobel prize in physics

I thought it was a maths result because the singularity theorems prove (that under physically reasonable conditions) there exist geodesics that come to an end - incomplete geodesics. It is usually assumed that the characteristic of a singularity is that the curvature divergences. However, this...
3. B 2020 Nobel prize in physics

Here is a link to Hawking's chapter's of the pop science/ bit of math book "The Nature of Space and Time" that was coauthored with Penrose: https://arxiv.org/abs/hep-th/9409195 This has the first chapter that introduces the singularity theorems, but it doesn't have the chapter written by...

Let me explain what this is all about. Say you start with 28 biscuits on your plate of you eat 2 of the biscuits. There MUST then be 26 biscuits left behind on the plate because this is the only way that: "Your weight before the meal + the weight of 28 biscuits = your weight after the meal +...
5. What makes a person smart?

I get what you were saying. And yes these are the questions that would be need to be answered when coming up with a definition of your biscuit. And there are many ways of defining your biscuit. I was assuming this definition was already in place and that you started with 28 of them.

This has me in mind of groupthink. People never learn the lesson of grouthink, they repeat the same mistake of groupthink. When people groupthink they never have contingency plans in case the preferred solution fails, and so they end coming up with ways of pushing the same wrong nonsense and...

Not sure how you can create a quantum superposition of number of biscuits correlated to a biscuit number measuring device.
8. What makes a person smart?

That is profound. You must have great difficulty buying groceries! Nothing in this store is objectively defined! I'm fairly sure it is possible to come up with a sensible definition of a biscuit. And then to state that the atoms that make up such and object cant be created out of nothing, and...

They actually believe they are disproving these statements: "If I eat 2 biscuits I will then have 2 less biscuits left behind" and "If I eat 3 biscuits I will then have 3 less biscuits left behind" Just to be clear there is no trick question involved in this, and they actually believe that...
10. What makes a person smart?

This resonates with me because I am personally attempting to reason with people who "think" the are disproving subtraction. You were taught at primary school that if you eat 2 biscuits you then have 2 less biscuits, if you eat 3 biscuits you then have 3 less biscuits - this is subtraction...

12. What makes a person smart?

I had a serious language developmental disorder (not dyslexia but probably SLI) as a child and young adult. I had to retake GCSE-English to get into university and I only managed to get a C grade required because I got help from a friend and my brother when writing essays. Nobody who has ever...
13. What makes a person smart?

Newton was not average, he was a absolute genius and saw further than all others of his time. He had flaws, when head on the mint he tortured people. And there was alchemy - well people didn't know better then.
14. What makes a person smart?

With advent of the internet there has been a resurgence in the flat Earth society and other crackpottery. I think you need to add further qualities of adhering to the scientific method and empirical evidence. It is good to push things forwards through doubt and curiosity, make advancements, but...

Aren't IQ tests adapted to the person's age?
