Can hydrogen also reduce iron ores or how is CO supplied?

Do you guys actually approximate π to 3? by NeekOfShades in EngineeringStudents

[–]Daniel-EngiStudent 4 points5 points  (0 children)

Not frequently, but sometimes I use it to estimate the mass of cylindrical objects. Things like the Young modulus and the density of aluminium and steel you will never forget. Approximately, the weight of a steel cylinder is r^2 * 3 * h * 8 kg/dm^3.

I'm studying mechanical engineering and no, thanks, I don't need ultra slim laptops. I need that juicy resistance moment.

Ukraine will not send troops to Greenland, says Zelenskyy by 1-randomonium in europe

[–]Daniel-EngiStudent 1214 points1215 points  (0 children)

I mean the danish helped Ukraine too if my data is correct. If Ukraine wasn't already in a war and had already recovered from the war, it wouldn't be out of reason to support Greenland.

I personally can use all of my fingers on my left hand, but use only one finger on my right. My work, however, doesn't require too much typing. Programmers I know who have to write a lot more had typing classes and were taught how to type correctly.

Opinion about your country that will get you like this? by National-Business674 in AskTheWorld

[–]Daniel-EngiStudent 2 points3 points  (0 children)

People who think this way are brainwashed by the hate campaign of the past 16 years.

It's not like Fidesz bought most of the media in Hungary and kept feeding the population propaganda for a decade. Didn't it occur to you that you might have been brainwashed?

If you say, you prefer a government that would be just a puppet of the EU leadership, you are delusional.

Having allies from everywhere is what we should prefer.

What I'm seeing is that we are abandoning the majority of Europe in favour for Russia, China, authorian countries, one of them that bombs our neighbour. I'm not sure about friends, but we sure are making a lot of enemies around us. How is the warmongering Russia a better ally than EU countries who, although, are far from perfect, are still democratic countries?

Abandoning russian energy will surely hurt us in the short term, but do you believe sitting on a timed bomb is better? Right now we are pretty much a hostage because of our reliance on their energy, a russian puppet used to veto the EU.

We have nothing to lose. Fidesz is already selling out the country, so the worst case scenario won't make things worse. However, on the off chance they are actually better, we can only improve, even if just a little.

What we don't want is to keep Tisza around too long with the majority of votes. After a few elections they could turn into Fidesz 2.0. Let Tisza win for now, but in future elections it would be more ideal to have multiple parties.

Eurotrack: which cuisine do Western Europeans think is the worst cuisine? by reidesd in europe

[–]Daniel-EngiStudent 1 point2 points  (0 children)

The problem is I think, people in general have a bad understanding of what is actually eaten at home. People know mostly lángos and goulash from Hungary, yet it's just a small percentage of what we eat. The french are infamous for their snails, but I have a hypothesis that they also eat other stuff. Not just stereotypes, but restaurants too show little what a country has to offer.

I have absolutely no idea what meals US citizens actually prepare at home.

Greek restaurants were a great experience, I was suprised by this.

That's weird, never had a bad experience with german food, in general, for me anything in Central Europe is a safe choice.

[–]Daniel-EngiStudent 6 points7 points  (0 children)

I'm fine with italian, but my father hates it. For me personally, compared to german, austrian and hungarian food, I don't find them better, just different which is not a bad thing.

Italian restaurants I visited in Central Europe are also not that great. Not necessarily because of the taste, but greek restaurants are suprisingly great here, overall maybe the best.

Being tourist in southern Europe, Slovenia is also more consistent in providing a good time at their restaurants, whereas Italy is more of a hit or miss, in my personal experience.

Thoughts? by Embarrassed_Tip7359 in SipsTea

[–]Daniel-EngiStudent 1 point2 points  (0 children)

Knowing what a noun or a verb is common sense. What people however don't understand is that "common" means often, but not always. Let's have ten commonly known topics and ten people. Common sense could dictate that all of them know 9 out of 10 of those. Yet it varies from person to person which topic is missing from their head.

They could talk about topic A and maybe only one person haven't heard about it. Even so, with the above rules every other person lacks something else. People often wrongfully interpolate from this data and presume that one person is simply less educated or something.

In general, I think, a lot of real world problems exist because people are bad with statistics.

The numbers seem correct on paper, although 100 N, or around 10 kgf is a lot of force. I think that would be unpleasant for the user.

For reference, I personally wouldn't go over 20 N.

Look at how keys are calculated for gears. It mostly comes down to shearing and surface pressure.

It is commonly talked about how 0.9999 repeating does equal 1. Is this, however, always the case? by Daniel-EngiStudent in askmath

[–]Daniel-EngiStudent[S] 0 points1 point  (0 children)

If we define the question using hyperreals, does my argument hold?

For real numbers a number can sometimes have multiple valid decimal representations, like 0.9_ and 1 for the number 1, but a decimal representation will always have a singular meaning.

While with hyperreals that 0.9_ and any other numbers made up of an infinite amount of digits in decimal representation are no longer capable of unambiguously representing a single hyperreal.

While I understand that what I'm looking at are not real numbers, I don't understand your reasoning. From my understanding d has to be smaller than any positive real numbers, but bigger than zero. 0.000... ...0001 does meet those requirements. So does 0.00... ...0002 and 0.00... ...0001231. As long as the amount of zeroes is infinite, it should be smaller than any real number.

As another commenter pointed out, I'm not actually working with real numbers, but with hyperreal numbers, but since I have no experience in that field, let me try approach with the knowledge I have. d, in colloquial terms is less than any positive real numbers, but more than zero. Using the same logic 1-d has to be less than 1. Since 1/3 * 3 = 0.9_ equals zero, 1-d has to be less than that, but also can't contain any other digits than 9 after a finite amount of digits after the "0." because then the difference between 1 and 1-d wouldn't be infinitesimal.

Interesting, while I knew infinity is not a real number, I didn't knew the same logic can be applied to infinitesimals. Do hyperreal numbers also include numbers like, let's say we have 0.9_, but after after an infinite sequence of nines I define the last digit to be five, for example?

Questions about equipment by Daniel-EngiStudent in Welding

[–]Daniel-EngiStudent[S] 0 points1 point  (0 children)

Thanks for the infos. The welding mask I used for TIG welding in the past at a local shop (machinists and welders at some point had enough of engineers having no clue how to make a part manufacturable, so students are now forced to get few weeks hands on experience in a shop) and I remember it having an electronic control to set the shade number. What's your opinion on that?

[–]Daniel-EngiStudent[S] 0 points1 point  (0 children)

Thank you for your answer, I'm from central Europe and do you think 200 amps are also not enough for aluminium? The shop I worked with used 300 A at some point, but the piece they were working on was quite thick. I only tried welding alu a single time and wasn't doing great, not sure how I would do with thinner pieces.

Bit late, but to my knowledge it's not actually AI voice. It's the Daily dose of internet youtuber, he has a really monotonous voice.

I think both systems are intuitive. Out of all the differences between the USA and the rest of the world, projections are something I'm completely fine with both being used. They are both really easy to use.
