There are brass alloys that contain up to 5% tin: https://en.wikipedia.org/wiki/Brass#Brass_alloys Copper reacts with concentrated sulfuric acid: https://www.google.com/search?q=concentrated+sulphuric+acid+copper+reaction

It is possible to pretend in spirit and in front of yourself a liberal, and actually be a conservative.. ;) Sexual activity does not have to result in the begetting of offspring. Unsatisfying sex, is a good indicator that such a relationship has no future. Hence the search for a new partner. I think it is much easier to get satisfying classical sex with a larger partner, because they are simply tighter. I'm a big fan of first date sex. If the sex is successful, that's when you can start talking about something else and start forming a real relationship. Months of dating, or even engagement, and then a first wedding night that turns out to be a “nightmare” is a recipe for wasting one's life. For becoming angry, bitter, prone to cheating, etc. Virginity can be lost only once. No amount of sewing, etc. will change that ;) You cannot expect/demand virginity from your partner if you are not one yourself.

People don't learn from their own or others' mistakes. In the UK, all natural forests have been cut down! This post-1920 peak is just a consequence of using more concrete, bricks and stone instead of wood: https://en.wikipedia.org/wiki/Forestry_in_the_United_Kingdom Doing a simple interpolation in 1920 on this graph, it is clear that if it were not for the cessation of timber use, 100% of the UK's forests would have been cleared by 2000. Now you jump in and want to reverse this trend. Good for someone with the mentality of a woodsman and lumberjack. If you don't cut down xxx trees it won't make money. If a butcher doesn't kill yyy animals he won't make money. If a fisherman doesn't catch zzz fish he won't make money, etc. etc. etc. All on a piecework basis without thought. I have no idea what IT has to do with it. There are companies that melt plastic from PET bottles and create filament from it for construction. The machine they show was 3D printed from garbage (material cost zero):

True. I love Labradors. They are so lovely.

..it seems to me that the Old Testament is filled with just the opposite examples. Starting with Isaac. https://en.wikipedia.org/wiki/Binding_of_Isaac Keeping the commandments also hardly counts as what you say.. Being (relatively) happy is the result of everyone doing the right thing and not committing sins, and other wickedness. In other words, do not do unto another what is not pleasing to you. Unless you are some kind of sado-maso etc. ;) (The Jews of >= 3,000 years ago did not foresee that someone could take pleasure in such things)

I was called to the board like a first-grader. Don't pretend someone else against yourself.. If you are evil, then be evil, and if you are good then be good. If you have the strength to overcome the evil within you, then you can become good.. Being evil is easy, sometimes it keeps you alive, but usually not very pleasant, because hatred eats you up from the inside and destroys you. Being good can also cost you your life, if evil wins, and kills you. The superposition between good and evil in quantum physics is not yet a solved puzzle.. ;) ..or the sources were misrepresented by the winners.. ;) I can easily refute this:

What can be done about this paradox? We will have to reboot the entire Universe! Are you okay with that? ;) Meanwhile, if something is at rest, something is moving, so we can find the reference system in which both objects are moving. This is called the FoR of the center of mass or the FoR of the center of momentum. https://en.wikipedia.org/wiki/Center-of-momentum_frame How about a little physics and/or science.. ? i.e. CoM FoR.

Just like Universe but currently smaller.. ;)

The correct one would be Mister or Sir @pzkpfw, because Asians terms i.e. brother, sister, aunt, uncle, grandma, grandpa, etc. do not work in Europe and an unknown person should be addressed as “Sir", "Madame”, “Mister” or "Lady" etc. if you want to be extremely gently. Referring to someone as “brother” can actually be considered an insult, because you don't really know each other. (In the company where I am often, you see people in their 70s who say “sir” to a salesman who is about 20 years old. In Asia I would expect something like “grandson give me this and this” ;) In my country, everyone we don't know is addressed as “Mr.” or “Mrs.”. (Most people have titles of nobility that they don't brag about..) Otherwise, everything else will be rude. If someone introduces himself by name and says, “Let's call each other ‘you,’” (you can propose it yourself, and wait for confirmation from the other side) then you can switch to a more relaxed form. But the form “brother” is heard only when someone is completely drunk at 3 am.. On a forum I would expect to speak by nickname. ps. From an Asian perspective you should call them “grandpa”... ;) And me you should call "superadmin eternal grandpa".. ;)

Every time you turn on, for example, a Minecraft server, a unique world/universe is created in which artificial intelligences live. Now you have a situation where these AIs are starting to ask who created us.. ;) Even better - the artificial intelligences create their own AIs (from which they can't break away and ask everything and treat as oracle).

You should start with the basics. Photoelectric effect. https://en.wikipedia.org/wiki/Photoelectric_effect Photon matter interactions: To begin with, search the web for titles appearing in the film + “Wikipedia”. One may wonder why these electrons are depicted as in the thumbnail above.(grouped together): https://en.wikipedia.org/wiki/Aufbau_principle The innermost electrons require higher energy to remove than the outermost electrons (fairly simple and obvious rule): https://en.wikipedia.org/wiki/Ionization_energy which leads us to historical knowledge about spectral lines: https://en.wikipedia.org/wiki/Spectral_line https://en.wikipedia.org/wiki/Balmer_series and https://en.wikipedia.org/wiki/Rydberg_formula If you are interested in history (i.e., a timeline of discoveries) If you need a demonstration of the quantum world with your own eyes, you need to see some kind of particle detector, such as a cloud chamber: other films: https://www.youtube.com/results?search_query=cloud+chamber If a word is incomprehensible, click the link on Wikipedia to see the description.

When you quote from an external source, you should use the “Wrap in quote” option. In my opinion, this is a rarely used option. But when quoting someone from a forum, there are much better tools - because they keep the forum member's ID and date.

You are not cunning enough. What if the passing was the result of the visit.. A stroke, like a heart attack, can be caused by nervousness and prolonged stress. Adrenaline is released, blood vessels shrink, cholesterol plaques break off, clogging blood vessels and less oxygen reaches a certain area of the brain.

I have a different value from here (but it is from 2000. Maybe current estimates are different): https://en.wikipedia.org/wiki/Carbon_cycle#Ocean "the deep ocean contains far more carbon—it is the largest pool of actively cycled carbon in the world, containing 50 times more than the atmosphere"

Are you talking about "Wrap in Quote" ?

You scared the newbies with your profile picture.. Wasn't it www.scienceforums.net before, and now it's scienceforums.net? Such a change has a devastating effect on search engine rankings. All links that search engines have ever recorded are now redirects. robots.txt differs between URLs: https://scienceforums.net/robots.txt https://www.scienceforums.net/robots.txt Sitemap from 1st is providing to http://www.scienceforums.net/sitemap.php I'd change it to https://scienceforums.net/sitemap.php i.e. http -> https and have them on the same domain name. All the links on sitemap here: https://scienceforums.net/sitemap.php are with http instead of https and are with www.scienceforums.net so are all redirects..

"The new ChatGPTs lie like crazy. Hallucinations in every second answer. The latest OpenAI artificial intelligence models for inference give false answers more often than older AIs. It's not clear why." "A few days ago, as we wrote about, OpenAI released new models for inference - including the most important o3 and o4-mini. They perform better than their predecessors in some areas - especially coding and math. Now we have found that, unfortunately, they make up answers much more often than the older OpenAI models. They hallucinate in greater explicit numbers than the company's previous reasoning models - o1, o1-mini and o3-mini - as well as traditional “non-comprehending” OpenAI models such as GPT-4o." "The response rate of new models with fake content is alarmingly high. OpenAI discovered that o3 showed hallucinations in response to as many as 33 percent of questions. This is a result achieved in a special PersonQA tool used by OpenAI.to measure the accuracy of the model's knowledge." "The 33 percent response rate with hallucinations is roughly twice the hallucination rate of OpenAI's previous reasoning models, o1 and o3-mini. These get scores of 16 percent and 14.8 percent, respectively, in the tests here. o4-mini performed even worse in the PersonQA test. In its case, hallucinations occurred in as many as 48 percent of cases." "That new inference models are more likely to lie has also been noticed by Transluce, a laboratory specializing in artificial intelligence research. Its researchers noted, for example, how o3 informed a user that it had run code on a 2021 MacBook Pro. “outside of ChatGPT,” and then copied the numbers into his answer. That's bogus, o3 can't do that." "There are also reports that links to non-existent Web pages, for example, appear in application codes generated by the new models." "No one knows why this is happening. Transluce, in an interview with TechCrunch, speculates that the increase in the number of hallucinations of the new models should be linked to the technique of teaching them through so-called reinforcement. In it, not only do their capabilities grow, but their greatest weaknesses are strengthened as well. " "So now it seems that the AI industry has entered a bit of a dead end. Last year, it focused on developing inference models after techniques to improve traditional AI models began to show declining effectiveness. Reasoning seemed to improve the model's performance on many tasks, without the need for huge calculations and the use of huge amounts of data during training. However, it now seems that reasoning models also have greater hallucination than standard models. As we now know, they are starting to get so big that they often derail the sense of using AI." (Translated by AI ;) ) All the code generated by the older ChatGPT did not work.. Almost useless for beginners, as they will have no idea where to start in order to get it to compile and work..

Fox News complains about tariffs. WTF.

They depend on the resolution.. It is called Responsive Web Design. https://en.wikipedia.org/wiki/Responsive_web_design and it is controlled by CSS media rules. https://www.w3schools.com/css/css3_mediaqueries.asp I think I found a really nasty bug - after merging two messages and trying to edit the original message, there is no content of the second message.. @Cap'n Refsmmat After pressing Edit and then Cancel, a blank alert window will appear: @TheVat The resolution has been slightly changed and the hamburger menu has disappeared: 980px triggers it As I already said you can try it with Firefox ctrl-shift-m

Quoting is not working properly. If I quote someone, it doesn't mention who the original author of the quote was..

I would say that owing someone a debt was one of the most common reasons for murdering that person, so as not to have to pay the debt.. War between countries is just an extrapolation of this to the large scale and in white gloves.

On a PC you can simulate mobile devices. On Firefox simply press ctrl+shift+m and reload page. On Chrome follow f.e. this: "Method 1: Using Device Simulation in Chrome DevTools for Mobile View Open DevTools by pressing F12. Click on the “Device Toggle Toolbar” available. Choose a device you want to simulate from the iOS and Android devices list. Once the desired device is chosen, it displays the mobile view of the website."

Here's a new line! I use ctrl-a to select everything and then press enter and then ctrl-v to have a new line at the top. Yes, it is annoying. But on mobile devices probably even more so. Alternatively, you can press enter in an empty answer, then select someone's text and quote it. The new line will still be at the top.

Go to Leaderboard, Past leaders and start clicking on 2, 3, 4 etc. It doesn't switch the page. Firefox on Linux on a PC. The number of likes and posts is not an exact number, but with the suffix k.
