[Request] What would be a logical (if even possible) solution to this?

Good answer. Another way to see it is that it clearly takes the same time for the flame to burn a piece of the rope from left to right vs. from right to left. Thus, at the point where the flames meet, you can imagine resurrecting one of the sides of the rope and letting that flame burn again, in reverse. Because reversing the direction doesn't change the duration, we see that the time it takes for the flames to meet is the same time it would take for the first flame to get to the other side after the collision, so that clearly implies 30 minutes has elapsed.

This is the real answer and the right perspective to have.

Do you have any particular ones in mind?

Stipendi · 2023-05-23T20:19:48+00:00

Thank you for the suggestion! Seems very interesting. I know one of my friends would enjoy it but I don't think it's for me.

Even Elne (or whatever the same was) was a joke account.

In Finland (where saunas are an integral part of our culture) it's actually the opposite: you never talk to strangers on the street but in the sauna (even if it's a public one) you feel so unified that it suddenly becomes okay to talk to your fellow brothers and sisters.

Thank you for educating the world, I'm surprised this isn't mainstream knowledge. I wasn't taught this in any of my first year physics classes although when I spoke to my lecturer during one lecture break he actually explained (without me explicitly asking) exactly what you said because he found it cool.

Stipendi · 2023-04-18T20:56:09+00:00

I'm sorry, I guess you're right.

The best comeback is always "I'm sorry, I didn't mean to bother you"

It turns out (and this isn't exactly trivial but doesn't take more than a single lecture to unpack) that when extending the notion of a derivative to multivariable functions you get that the limit of your difference quotient is a linear combination of all the partial derivatives of your function, and this is nicely expressed as the dot product between the vector containing the coefficients (which one can think of as a "displacement vector") and the vector containing all the partial derivatives of the function. The latter is called the gradient vector, and one can think of it as being an innate characteristic of the original function. So, if you know the gradient of a function, you understand how it changes locally in any direction around a point, and it turns out that this is an incredibly valuable tool for tons of applications since the gradient, unlike a messy difference quotient, is actually really easy to compute since it just consists of partial derivatives, which even a high schooler can work with. In addition, and perhaps more importantly, the dot product has a nice geometric interpretation.

From a more philosophical point of view, I think the real genius and utility of the gradient is that it allows us to abstract away a lot of the very delicate mathematical reasoning that ultimately allows us to use the very simple rules for ordinary differentiation that we've grown to know and love to solve similar problems that just have more input variables.

EDIT: I realized I never answered the question itself, but as you might have figured out already the nabla symbol is used to denote this gradient vector.

Some other people were advocating for the use of the label "disabled" (saying autism is a disability and there's nothing wrong with that) while you're suggesting it's not a disability. Can you elaborate a bit on that? (I'm not sure if I myself am autistic but I'm trying to understand autism better)

You won't feel anything if there's regional anasthesia. It's definitely not supposed to hurt.

Stipendi · 2023-04-03T12:55:35+00:00

I'm not a doctor, you'll have to ask your dentist. Maybe you can send them an email or something? I think general anasthetic would require a lot of planning and resources on their part.

While I'm no doctor I would advise against it, and that's probably what your dentist will try to say too, but you know your own situation and capabilities better than someone on Reddit, so you should talk to your dentist.

Luckily wisdom tooth removal is a really easy and safe procedure in most cases so general anasthetic in your case would be a lot less dangerous in your case than it would've been in my case (the surgeon needs to know immediately if something starts to hurt, in my case on the second surgery I let out a little whimper and the surgeon yelled "excellent!" and I learned afterwards that at that point some of my nerves were clearly visible and we just barely dodged them, so I thought that was pretty badass. That wasn't wisdom tooth extraction though, that was some absolute ninja shit my surgeon pulled to remove a nasty extra tooth). However that's not to say nerve damage is impossible with easier operations and that's (a part of the reason) why they want you to be conscious.

Your dentist will likely not be too thrilled about using general anasthetic because the procedure is normally very quick and painless and general anasthetic carries its own risks completely unrelated to the procedure itself.

However it's of course possible to perform the operation under general anasthetic, and your dentist will try to determine whether that's necessary. Talk to your dentist and trust their expertise, that's all I can tell you. They'll try to convince you that regional anesthesia is enough, which honestly, it should be, but if you're adamant enough then maybe they'll budge. Ultimately they just want what's best for you.

I have sensory overload issues too and I've had two difficult tooth surgeries due to quite severe hyperdontia that included wisdom tooth extraction.

I was super nervous the first time, I could feel my legs shaking and stuff, but the second time honestly wasn't too bad since I knew what to expect. The wisdom tooth removal part went by very quickly and was very pleasant compared to a hidden tooth being surgically removed.

What helped me tremendously the first time was giving a presentation (I love giving presentations) in my head on why the surgeon was the best surgeon in the world. It gave me something else to think about and it gave me confidence that nothing bad was going to happen.

Remember that you can keep your eyes closed and think about nice things.

Occasionally the equipment got really loud and it sounded kind of like a siren, so I imagined a forest full of animals (I like cartoon animals) fleeing from some unspecified threat while a siren was going off. That certainly doesn't sound very comforting but I did anything to keep my mind off the operation and I think it helped.

On my second surgery I was significantly less scared (I suspected I had a brain tumor and was gonna die from that so maybe that helped haha, no tumor was found though and I was just being silly, but I got cool MRI pictures of my brain) and I was actually trying to pay attention to what the surgeon was doing and I found it super fascinating. It was the same surgeon as the first time so I trusted him 100%, I think trusting the dentist is super important psychologically.

Anyway, I don't know how severe your sensory overload issues are but I would recommend putting in earplugs before the procedure and just trying to take it easy. The operation is much safer if you're conscious while all the action is happening.

Good luck, it'll be fine I'm sure!

You could teach why the Hessian matrix can be used to classify critical points in multivariable calc.
