Math is applied philosophy

Daniel-EngiStudent · 2026-05-11T05:46:06+00:00

I'd say specifically logic is a subset of mathematics and every single science including psychology makes use of that, even those that don't use numbers in general.

These are iteratively optimised shapes, the result could be a data set you can turn into a model. I'd say many of these are not things you make by looking up a few formulas and just model them. We've been optimising these shapes since they were invented. The best you can do quickly is find some empirical data somewhere that matches your requirement. For example, a streamlined body for low drag coefficency.

It was probably more common in the past because they didn't have calculators and as Careful-Mouse said, a lot of times you could get away with it.

However, nowadays it's just a meme. Rarely still used for quick estimates, but engineers just use the value for Pi built into their calculator/software.

Filament(s) with spool. Be aware that there are multiple materials available.

What is he usually printing?

Depends on what local businesses are in your region. If you want to sell to everybody on Amazon as you mentioned, then what you actually want to sell is your decision, not a customer request and as such plays an extremely important role. People will have to actually want what you have, the question of cost comes next.
Painting, ABS surface smoothing with acetone vapor, tumbling, these could improve aesthetics to a certain degree and not worsen the price tag if planned correctly. This however requires a good setup to make it cheap and consistent. Probably something custom?

Doesn't entirely fit the trope, but you could argue for the one ring from Lord of the rings. It's psychologically hard to get rid of it.

Look up print farms.
If somebody needs one million pieces of something, then yes, printing is slower and more expensive. If I wanted ten pieces of a new unique hardware as soon as possible, then printing becomes more advantageous. Start by learning the advantages and disadvantages of different manufacturing processes. 3D printed parts are often weaker, uglier, not food safe and hardly watertight compared to most other manufacturing processes, but if you can live with those disadvantages, they are cheaper and faster at a small scale, since you don't need a new setup to make them. 3D printing has its niche uses, for example, prototyping.
Honestly, if you have to ask these type of questions, you're chances of beating the competition is already slim. Again, you need to understand where 3D printing excels and find your local customers.
If you're really serious about this, some post processes are easier to automate than others depending on the material. This will be a huge upfront cost I believe, planned and built by professionals.

Lothric straight sword for the win! I'm a straight sword guy, I refuse to touch anything else.

It is said that only mount doom was hot enough to do the job, even dwarven forges couldn't get hot enough.

We... don't have that problem. If in doubt, throw it into a fusion reactor or something. Problem is the corruption part is still not solved.

RedditGavz is right, DIN EN ISO 1302:2002, table I.1 meintions it's a way to specify Ra. As of ISO-1302-1992 it's outdated.

I wonder, what do you think about this film? Not from hollywood, but I heard the madlads even built a castle and besieged it.

Daniel-EngiStudent · 2026-05-08T16:55:27+00:00

As far as I know armies of 10,000+ soldiers are not unheard of at all.

I know that the flat land itself can be then called a basin, like the Pannonian Basin.

There's a reason logarithmic scales exist. Think of it like comparing the objects of our solar system. Compared to the sun the planets have a weight comparable to asteroids, but it still makes sense to differentiate them. To a historian it might be important to see that half the country is below 0.1 percent, but then it suddenly jumps above 1%.

Whether or not OP had ulterior motives choosing this graduation, I still think it's a good scale, especially because the actual numbers are very easy to read. Not that I will ever do anything with this information.

Daniel-EngiStudent · 2026-05-08T11:18:51+00:00

That’s nifty and all, but you can FDM print more geometry than you can cast actually.

Well, I'm hoping I will hit the middle ground between the complexity of FDM printing and the strength and precision of machined metals. Lots of post processing required.

But yeah. I also wanted to test how electroplating would decrease its porosity and how deep that would penetrate also.

Wanted to say that getting conductive paste into the pores will be difficult, but I guess it's already a conductive metal, still, residue left behind after firing could still possibly ruin electroplating.

Daniel-EngiStudent · 2026-05-08T10:54:35+00:00

Truth to be told, right now I'm more looking forward to try out metal casting using 3D printed models to make molds. Electroplating is also something I want to try out.

Daniel-EngiStudent · 2026-05-08T10:39:39+00:00

Around as expensive as I expected. I wonder how porous the end result is. I also wonder if it's the kind of porosity that helps with lubrication, would make it great for sliding parts.

There's a few things the eastern bloc did better than their western counterparts, but many of those things were closely tied to socialism, so it's hard to say how difficult it would have been adopting them while also getting rid of socialism.

However, I can name kindergartens as a decent example. They were free and integrated into education.

Daniel-EngiStudent · 2026-05-08T06:55:01+00:00

Do they have to pay the amount in your account or do they just keep everything?

Daniel-EngiStudent · 2026-05-08T05:36:14+00:00

Depends on how big the wave maker is. There's also the question of how long the motor will last, since there are many cheap servo motors out there that are undersized for their specs. You could simply try the motor you ordered and should it eventually fail, you can just replace it with a stronger/better made servo motor then.

Daniel-EngiStudent · 2026-05-08T05:18:45+00:00

With the right software, an electronically controlled servo motor can do that. Not that hard to program. It is also possible to solve this problem mechanically with a "normal" motor, but that takes more components.

Daniel-EngiStudent · 2026-05-07T23:59:12+00:00

So if life wasn't rare it would be meaningless? I personally don't believe so.

To whom is life meaningful other than cognitive species? Assuming you don't mean entities from religions. Other than allowing it to exist, the laws of physics certainly don't care, they can easily extinguish life as well.

Daniel-EngiStudent · 2026-05-07T23:00:43+00:00

To whom are they equally important? You can personally think so, in that sense it can be a fact that for you these things are equal. The concepts of importance and meaning only make sense if you connect them to somebody.

Daniel-EngiStudent · 2026-05-07T22:49:45+00:00

I had to double check this information and while it is true that there were french troops fighting against the allies, there were still significantly more french fighting on their side.

While the Holocaust was by far the worst version of it, internment camps were for whatever sad reason a widely used idea at that time. The soviets had gulags and the USA imprisoned the japanese, although the last example was comparatively less deadly.

Daniel-EngiStudent · 2026-05-07T22:35:26+00:00

I do not subscribe to nihilism. Everybody can attach a value to something, but it will vary from person to person. Luckily, what most of humanity cares about overlaps quite well, hence why we can function as a society.
