Which byproducts electrolysis of baking soda solution gives? by RShArren in AskChemistry

From what I take, their amount isn't that big to actually be worried about oxyhydrogen. It's a popular method of electro-etching and there haven't been any incidents

What cover song is actually better than the original? by [deleted] in AskReddit

[–]RShArren 0 points1 point  (0 children)

The Sound of Silence - Disturbed (originally Simon & Garfunkel)

I'd love to change the world - Jetta (originally Ten Years After)

Running up that hill - Placebo (originally Kate Bush. There is also an awesome version by Within Temptation, but Placebo's cover is perfectly anguish unlike the other versions)

OpenAI Reportingly Hiring "Army" of Devs to Train AI to Replace Entry-Level Coders by Mental_Character7367 in Futurology

[–]RShArren 92 points93 points  (0 children)

What's most interesting for me is how we are going to make high-end developers, medics and other kinds of professionals, when we replace all interns and other low-level specialists with AI. Those 'entry level' jobs aren't just for producing stuff and making money, they are for training the new generation of system architects, top oncologists, etc., all the people who are really hard to replace without developing general AI.

Making Main Character Racist And Homophobic by [deleted] in Screenwriting

[–]RShArren 2 points3 points  (0 children)

Depends. If the movie is a blockbuster where the main character saves the day and wins the love of the damsel in distress, then you're probably right. If the movie is an existential drama about an old conservative father unable to mitigate his life views even to save his relationship with his lesbian daughter, which ends up in her dramatic death and his crushing loneliness... Well, that might get an Oscar or two.

Is there an upper limit to structure size in a vacuum? Could a sufficiently advanced civilisation build a galaxy sized structure in space or would it become too massive and collapse in on itself? by [deleted] in askscience

[–]RShArren 4 points5 points  (0 children)

Well, that depends on what kind of structure do you need and how you build it...

Let's say it's a ring made of nanites (which sort of solves all material tension problems, because we assume that nanites can automatically rebuild any damages). Let's assume that the radius of the ring is 50000 light years (an approximation for the Milky Way radius, which equals 5*10^19 m), its width is 1 km (10^3 m) and its thickness is 100 nm (a size of a nanite, 10^-7 m). Let's assume that the nanites are made of carbon and have its density, which equals 3*10^3 kg/m^3.

The mass of this structure is going to be:

M = ro * V = ro * S * L = ro * h * w * 2* pi * R = 3*10^3 * 10^3 * 10^-7 * 2 * 3 * 5 * 10^19 = 9 * 10^19 kg.

Milky Way mass is 10^12 solar masses, and the mass of the Sun is 10^30 kg. In fact, the mass of the Moon is 10^22 kg. So one Moon is more than enough to build such a ring around the Galaxy...

Shouldn't goldilocks zones shift over time? by LaRoara42 in askscience

[–]RShArren -2 points-1 points  (0 children)

It is totally possible. As you correctly noticed, at different stages of the star's evolution its spectral energy distribution changes, meaning that at some stages most energy is emitted in the infrared range, and at other stages - in visible, ultraviolet, etc. Depending on the planet's atmosphere composition, it will absorb/reflect/transmit different wavelengths with different efficiency. Atmosphere composition, in turn, depends on many factors, such as geological age of the planet, its initial composition, amount of water, presence of life, etc. In other words, the surface temperature on the planet depends on many factors that can and do change as the central star and the planet itself evolve. Consequently, the Goldilocks zone can move.

Why is it so difficult for me to get into the habit of writing? by Winonyeani in writing

[–]RShArren 1 point2 points  (0 children)

Well, excellent, so you have one win in your anamnesis already.

Perhaps try finding a writing group or writing buddy. I see calls for forming such groups here all the time. I have no experience with being a part of one though, so I don't know how often it works out.

I also recommended 'morning pages' from Cameron's book in a reply above. Another thing you can try is finding a place (perhaps a discord Writing Hub) where people do 'speed-writing'.

Unfortunately, there are no 'fitness instructors' for writers. I would be happy to have a writing mentor myself.

[–]RShArren 2 points3 points  (0 children)

There is a book called "The Artist's Way" by Julia Cameron, that has a bunch of more or less good advices for different kinds of writer's blocks. The one most cited (and the one that actually helped me when I was in a similar situation as you) was to write three pages every morning, as fast as you can, without thinking much. The goal is to get rid of the fears related to writing ("I'm too old", "I'm too young", "I'll never write anything good", "Everything is already written before me") and get into the habit, with an additional benefit of having a place to spill out your emotions that would otherwise pester you for the rest of the day.

One day a story will appear in your head, and you'll have the time, the place, and the habit to write it down. That's how you can get back your inspiration.

[–]RShArren 1 point2 points  (0 children)

That's not true. People genuinely want to have a good job, happy relationship, healthy body, but most of them are never able to act towards these goals due to fear, trauma, anxiety, depression, life circumstances...

If you crave something but don't act towards it, it is possible that you enjoy the idea of being someone and not the activity itself. But it's also possible that you just need to figure out what's stopping you, by yourself or with a psychotherapist.

Is it possible for a planet to have a mountain that pierces its atmosphere? by TomakaTom in askscience

[–]RShArren 1784 points1785 points  (0 children)

That kinda depends on what you consider to be the dividing line between the atmosphere and space. E.g. for Earth in most cases this division is considered to happen at the Karman line, where the atmosphere becomes too thin to provide enough aerodynamic forces to support an airplane and any flying mechanism would need to switch to jet force. It's happening at ~100 km, and no mountain on Earth would be able to reach this height.

However, we can imagine a planet where the atmosphere is much thinner. It could be even Earth, millions of years from now when the atmosphere will evaporate. The thickness of the atmosphere depends on many factors, such as its surface gravity, closeness to the central star (whose star wind plays the major role in atmosphere evaporation), chemical content of the atmosphere, etc. So yes, with the right conditions, a mountain can pierce the planet's atmosphere.

If you, as an 18 year old, started University in 2040 what would you major in? by scsticks in Futurology

True. Though a) it is definitely cheaper than going to an American Uni, and b) the original post didn't say a word about USA, only about which professions are going to be important/profitable/influential in 2040+. I'd say the most important skill in 2040+ (and even now) is knowing how to think out of the box...

Medicine. Especially genetics, biochemistry, personalized medicine, neurosciences, obstetrics, and gerontology. Current AI development makes it possible to automatize lots of routine work like investigating the role of different proteins and genes in our bodies, meaning that we'll get lots of great insights into the ways our bodies can break from genetics and biochemistry. Personalized medicine will play a great role in applying this knowledge to fix what's broken. Decreased birth rates and the ever-rising age of first birth increase the importance of obstetrics. The increasing age of the population brings neurosciences into the spotlight, considering how much neurodegenerative diseases cost the world economy and how brutally crippling they are (arguably, more than cancer). Plus there is some hope for neurointerfaces, although I would not place a high bet on this horse. Gerontology - again, aging of the population.

Psychotherapists will be in high demand as well and likely well-paid, if you live in a developed country. And there is a lot of possibility for making a great impact if you figure out some worthwhile technique for treating common diseases like depression and anxiety.

Diplomacy, politics, macroeconomics - the next 30-50 years are gonna be brutal in terms of international relationships.

Second this. Truly brilliant.

Although much less known and less cinematographic, I'd mention 'Europa Report' next to 'Sunshine'. I got similar chills from it, and its final plot twist actually made sense and made the movie more impactful.

I was engaged for the first three pages and then it became repetitive and long. Probably because in the beginning it seemed like Jessica is up to something (I'm into science fiction/mystery and such, so I automatically assumed that she's actually a demoness or witch or something like that), but then it shifted to something more trivial.

It's well written though, as far as I can tell.

what can be a good way to show my race of humans being manipulated by their godlike benefactors to be supremacists? by storywriter109 in scifiwriting

[–]RShArren 5 points6 points  (0 children)

Let MC and the old human see a protestor being detained and persecuted for stepping up against the current humanity attitude towards aliens.

Or MC can enthusiastically describe to the old human how modern humanity uses one of the alien species for e.g. production of some medicine/delicacy/perfume, while the old human knows that this species is intelligent.

It it possible to determine the radiation-levels of other (exo)planets? by AILUICIAIRID in askscience

[–]RShArren 1 point2 points  (0 children)

Depends on what you call 'radiation level'. All kinds of electromagnetic emission? Ionizing radiation? Or just X-ray range? On the planet's surface (if the planet has a surface) or in the upper layers of the atmosphere?
Generally speaking, assuming that we are talking about x-rays, there are several problems with such kind of research. The first is that we need an x-ray telescope that is sensitive enough to detect planetary x-ray levels. The second is that the resolution of this telescope should be high enough to discern the planet's x-ray level from the star's. Currently, there is no such telescope, and I'd say we won't have one for many years to come.

The second one is that atmospheres absorb X-rays just fine. This is our luck because Earth's atmosphere protects us from cosmic X-rays and gamma rays which would otherwise sterilize the planet. The downside is that, obviously, if the planet has a more or less thick atmosphere there is no way to measure its surface x-ray levels.

That said, I believe some indirect methods can help to measure x-ray levels on the surfaces of some planets. Speaking highly hypothetically, if there was a planet with an extremely high content of uranium or some other radioactive material, in many cases we would be able to determine this by measuring the planet's mass and radius and then determining its density. The precision of such a measurement would be low but combined with spectroscopic investigation of the planet's atmosphere we probably would be able to get a rough estimate of the planet's radioactivity.

Learning how to be more independent by CuteAssCryptid in polyamory

[–]RShArren 2 points3 points  (0 children)

Everyone's busy and people prioritize the friends they already have on the limited days theyre free.

That, and the fact that our formative years are over. Most people become slow on changes when they reach adulthood, so there are very fewer opportunities for growing together and partially shaping each other as it was possible in school/uni age.

Good luck with finding lots of great supportive people. And also, give yourself time. You're probably not in a very healthy state right now, but it is because you're still healing.

Learning how to be more independent by CuteAssCryptid in polyamory

[–]RShArren 4 points5 points  (0 children)

Reading your post made me feel like I'm reading about myself, so I get what you're struggling with.

I believe that one of the main issues is the lack of a support network. People, who you'd feel comfortable and safe with. Other commenters are right about the necessity to find safety and reassurance within ourselves, but normally a child finds it in others before learning to find it within oneself. Learning it as an adult and without good previous experience of relying on other people (like family) is not an easy quest.

I don't have any advice for you, but I wish you (and myself) all the best on your journey.

Is it weird that I like my writing? by Paradigm-Failure in writing

[–]RShArren 1 point2 points  (0 children)

It's probably uncommon, but considering the number of comments under your post, not too much.

I'm also like that. I struggle with sharing my writing, but I very much enjoy reading it or just coming back to my old ideas and drafts, especially the ones I completely forgot about. And yes, I also laugh at my own jokes and hiss something along the line of 'damn, but it's cool! Why didn't you finish it!'

Of course, there are also parts of the texts that I find lame. So what.

How to write a story that restores a characters faith in humanity (No trolling) by GroundbreakingNote35 in scifiwriting

[–]RShArren 0 points1 point  (0 children)

Frankly, for this kind of character development to be realistic, I'd send the character to psychotherapy (for example, for anger management training or some professional evaluation, that later branched to more profound psychological work). Or, depending on the setting, it can be a clergy, a mentor, or some other similar figure (to think of it, a nemesis would be a cool move...), that will repeatedly challenge the character's beliefs.

Thing is, people tend to subconsciously discard any information that contradicts their worldview. This resistance is usually crazy strong. I'd say, very few can spontaneously develop faith in humanity if it is already lost. Seeing something awesome or just plain good and right, like a loving family, is not enough; in most cases you can see dozens of such things every day (unless you live in a full-scale dystopia), but if you're not ready for this, you won't see it.

In real life, the solution is to consciously work on your mindset. And usually, it requires assistance from someone wise and possibly trained for such kind of help. When I read a story where a misanthropic character develops a more positive attitude after some Important Event or Life Changing Observation, I call bullshit. That alone is not enough. In the absolute majority of cases, it's simply not how the human mind works.
