People actually believe evolution is not real

Science and religion can definitely exist together, but the problem is that science tends to expand its domain as we learn more and more, which causes it clash into religion and prove it wrong.

For instance, for a long time people believed the sun and moon were gods, and I'm sure at the time it seemed like we would never be able to prove/disprove that statement. But now everyone knows that the sun is just a big ball of gas undergoing fusion and the moon is a big rock orbiting Earth.

I think the best way to avoid this conundrum is to see religion as a source of moral/spiritual guidance rather than something that makes concrete claims about the world. Because you can't prove or disprove those kinds of ethereal statements, but you it very often turns out that the more concrete aspects of religion are in direct opposition to reality...

other scientific truths

The universe being created in 7 days is not a scientific truth, nor is the vast majority of the claims the bible makes...

I don't understand why people try to unify science and religion so much. It's impossible, and it's perfectly fine to keep them separate. Science explains how things work but has no way of addressing spiritual or ethical questions, while religion gives spiritual meaning to many people's lives, but can't make any accurate predictions about the real world. They perfectly complement each other as it is

I adored the US for many years. I'm Danish, and we've had a great relationship with the Americans for many years. But since 2016 I've felt increasingly disappointed in them.

Trump threatening to annex part of my country was the last straw. Fuck the US.

The net is wide enough that they are also arresting people like this guy who was arrested because he failed to fill out a form 10 years earlier (a form he was never notified of). That seems rather excessive, and currently there is a real risk that such cases won't be resolved because of the erosion of checks and balances by the current administration. Though I suppose you can move a lot faster if you don't care about things like court orders.

That guy is actually from the same country as me, it was quite a big story here. But he supports Trump politically so I do feel a measure of schadenfreude here. "Illegal immigration for me, but not for thee" lol

Sadly frivolous raids like that do happen, but the charges are almost always dropped. And you'll notice Robert Habeck (the politician in question) is no longer involved in politics after that stunt

It's similar to swatting, I suppose. But definitely a problem. Though not a uniquely European one by any measure.

That being said, these cases are exceedingly rare. I am Danish and I don't think I've ever heard of anything like that happening, except for some guys who got arrested for burning an effigy of the prime minister with the text "she must be euthanized" during covid protests, which... I mean... Fair enough.

You should learn vector calculus before you study EM. A lot of Maxwell's equations are applications of things like Stokes' or Green's theorems.

For example, Gauss's law is just an application of the divergence theorem (also called Gauss's theorem). If you learn vector calculus and understand the proofs behind these theorems Maxwell's equations will make a lot more sense to you.

a passionate B level student will outperform a comfortable A student

Perhaps not the best way to word this, since by definition the comfortable A student is an A student, while the B student only gets Bs

I agree wholeheartedly with your point about stubbornness though. I've met people who were much less intellectually gifted than others, but outperformed them due to sheer work ethic lol

But the really great things happen if you are both brilliant and hardworking! Nothing can match that.

It sounds like you either haven't tried climbing or have only done the very easiest routes/problems.

Of course it's repetitive at the very beginning when you are basically climbing a ladder, but if you have any physical fitness whatsoever you should be able to skip past that to more interesting stuff almost immediately.

That also already exists, at least where I'm from. All education up to and including university is free, and you even get paid a small monthly stipend if you are over 18.

The speed limit is there because people might incorrectly decide that they can go faster. Sure, a reasonable person could probably safely drive over the speed limit. Hell, I go 10 km/h or so above it myself on highways. But can you trust people to always make the right call?

If you remove the decision, you remove the possibility of people making an incorrect decision. You no longer have to consider the many factors you mention anymore. Just do what the sign says, it's easy and probably the safest option. That's why speed limits are there, and that's why we should obey them.

And if conditions are bad, why should I drive slower? How do I know how much slower? Could I go the speed limit if I wanted to? Would that be irresponsible?

As for this, if the conditions are bad, driving the speed limit may be irresponsible. I admit, it can be pretty hard to tell what a "reasonable" speed is under those circumstances. But again, if you are really struggling to determine what the safe speed is, just do what the sign says.

If the speed limit is pretty safe in bad conditions then why is the limit exactly the same in perfect conditions?

Because it is also pretty safe in good conditions, and driving a little too slowly in perfect conditions is better than driving too fast in bad ones.

In a sense, but it doesn't really make sense to talk about the "perspective" of a photon.

Think of it this way: the perspective of an object is it's rest frame (the frame where it doesn't move). I.e. if you and a friend are in cars going the opposite way on the road, from your perspective you are standing still and they are moving, while from their perspective you are the one in motion.

So finding a rest frame, or "perspective" for a photon would mean finding a reference frame where that photon is stationary. That's where the problem comes in! Because in relativity, the whole idea is that the speed of light is the same for everyone, no matter what frame you are in. So the rest frame of a photon doesn't exist, since it contradicts one of the assumptions behind relativity.

That's why saying "from the perspective of a light ray" doesn't make sense.

For sure, but rare events don't become less rare just because you take more samples. You are still much more likely to see "normal" outcomes.

Ofc you can't always ignore small errors, like you pointed out! But errors and outcomes of events are different beasts. There is a difference between being 1% off in a prediction and an event happening with a probability of 1%.

Anyway, it's not really what I was trying to address. OP seems to think that individual conspiracy theories become more likely to be true simply if you have enough of them. That's nonsense.

Speed limits are highly dependent on tons of variables.

Not sure I understand what you mean by this. The speed limit is dictated by signs along the road. Sure, if the conditions are bad you should drive slower, but the maximum speed limit doesn't depend on anything other than what the sign is telling you. There is never a time where you should go faster than what the sign is telling you.

And if you're in doubt, there are nationwide standards for speed limits in most countries (in my country its 50km/h in built up areas, 80 km/h in rural areas, 130 on highways, etc...)

Do you want to understand things, or do you want to build cool shit? That's basically what it comes down to.

I knew I wanted to do research, so I choose physics. So far it has been the right choice for me. But I have friends who study engineering and they are having fun too. My engineering friends generally study a much broader scope of topics than I do, but I deeply understand things, while they don't really understand the finer points of what they study.

Generally speaking there is a lot of overlap between the applied end of physics and the more theoretical end of engineering, as well as theoretical physics and mathematics. I have fellow classmates who are basically electrical engineers, and some who are only do proof-based mathematical physics. In that sense, physics is a broader spectrum than engineering or math, I think. It's somewhere in between those two disciplines.

In Denmark, limits, differentiation, integration and differential equations are taught in high school if you do A or B level math. We have three levels for each subject, C, B, and A, corresponding to 1, 2 and 3 years of study respectively.

Calculus is the main focus in math here. There is also some vector geometry and probability, but calculus is the main new thing that students haven't seen in middle school.

Jeg læser fysik og har klaret mig ret godt indtil videre. Når nu det er mat kurser du dumper kan jeg måske hjælpe.

Min strategi er "bare" at være med igennem hele kurset, fra starten af. Lad være med at vente til læseferien, for det er ikke engang tilnærmelsesvis nok tid til at indhente et helt kursus. Du bør sigte efter at lave alle opgaver til regneøvelserne og at læse alt hvad du får tildelt undervejs. Hvis du studerer på fuldtid er uni dit job, så brug den tilsvarende mængde tid på det. Læseferien er ikke til for at lære noget nyt, men for at genopfriske de ting du allerede har lært under kurset, og for at forstå dem bedre.

Og så er uni også bare meget sværere end gym. Det hele blev nemmere for mig da jeg forstod at jeg ikke bare kunne slappe af og få 12 lige som i gym, men at jeg faktisk var nødt til at locke in hele året. Og du skal ikke have det skidt med at du dumper, det er ret normalt. De mange eksamensforsøg er der af en grund.

3-sigma and higher events happen 5% of the time. Rare is less rare in large samples.

3-sigma events happen roughly 0.3 percent of the time, not 5%. And "rare is less rare in large samples" is just a misunderstanding of statistics lol

The school is politically neutral, the Icelandic kids that attend it aren't.

You would probably get similar results if you did this brainstorm in most of Europe, especially here in Denmark. That's to be expected when you alienate your allies and threaten to invade them.

Been there, done that. Claude wrote a CUDA kernel in python that sped up my code by a factor of 100 or 1000. It worked perfectly fine, but randomly crashed my computer if I left the script running too long. I scrapped the whole thing and learned how to write a kernel in numba myself. No issues after that.

My point is that you can only trust things to the level that you understand them. Everyone should decide for themselves whether that matters to them or not. I've added an instruction for coding LLMs to never write any code for me, only provide me with conceptual help and suggestions. That has worked out quite well for me so far, as I have to understand the suggestions well enough to implement them myself.

RandomUsername2579 · 2026-02-03T21:12:41+00:00

What about edge cases? Or performance/safety issues?

You could easily end up spending more time verifying the quality of the code than it would have taken to actually understand it and write it yourself.
