You can safely ignore that: Relativity and classical mechanics make different predictions, and we've done the experiments. But if you travel into the weeds, a constant speed of light is not the only way to arrive at those predictions:

I thought you could write general relativity in a coordinate free manner that specifically doesn't rely on strong coordinate choices Indeed. But even before you start messing with the formalism, the metric alone cannot be used to def

It's less about the metric but the choice of space/time decomposition.

by cygx 7y ago
Because we define the speed of light in terms of spatially homogeneous and isotropic inertial coordinates. We do that because we want "the statements of the natural laws [to be] as simple as possible" (Poincaré), but it's not

Fun fact: The speed of light is only constant by convention. There's a nice creationist paper where they try to twist physics into a pretzel in order to make it fit the biblical narrative, using a convention where the speed of infallin

Heidegger's response looks rather weak to me, but note that Marcuse also didn't get his point about the treatment of East Germans by 'one of the Allies': Not too long ago, I saw an exhibition on the 'Wolfskinder&#x2

The Khasi people of north-eastern India often get cited as an example: https://rady.ucsd.edu/faculty/directory/gneezy/pub/docs/gend... See the comment by obviuosly for some caveats.

Nothing wrong with it as long as you avoid the traps of naive essentialism or fallacious appeals to nature.

Nurture can trump nature, though: There are matrilineal societies where competitiveness is considered a feminine trait. As is often the case, it's not simply either/or.

As I see it, there are two orthogonal roots to functional programming: Mathematical functions on the one hand, and lambda expressions/closure/higher-order functions/... on the other. The former implies immutability and techni

I would like to remind everyone reading this that there's no such thing as "linear indexing" of user-perceived characters in Unicode. There is if you dynamically assign virtual code points to grapheme clusters.

Untrue, medieval period and dark ages typically refer to the same time period that lasted until the 13th century. The term 'dark ages' is used by some as reference to the early medieval period specifically, which may also be cla

OP suggested that 10% of people think there are more than 50% of flat-earthers when the real number is 0.1%. Phrased another way, 10% of people expect half the people they meet will be flat-earthers when it's 1 in 1000. Doesn't se

The second question does not ask for an estimate of prevalence, but to pick the answer you think most popular. You can over-estimate the amounts as much as you like as long as the majority choice remains the same, ie it would not matter whe

If there are only 0.1% of flat earthers, why would 10% of people think it to be the most popular answer? That does not seem realistic at all. Or did you interpret the question as suggested by bena in his sibling answer, ie as an estimate fo

That was left as an exercise for the reader :p As you said, knowingly going against the consensus does not an expert make.

Let's look at another toy example, using made-up numbers: Q: Is the earth flat? Yes: 10% No: 90% Q: What do you think most people will respond to that question? Yes: 3% No: 97% Analysis: Yes: 10
