1. ## Hey guys im back!

After a long hiatus, nearly 7 years, I have returned. I went and joined the air force, got a bachelors of science, a minors in math and a minors in bio; and currently work in IT/ software engineering. Any of the old members still active?

2. ## Calculus

The question was not about using computers to solve calculus problems anyway. Since computer science is mainly about proving asymptotic behavior of the maximal running time of algorithms, there are lots of results in computer science that cannot or only with some extra difficulty be proved without calculus, e.g. typically using that the limit behavior is given by a suitable Riemann integral. Generally you cannot escape using limits to get general bounds on running time.

3. ## Collatz Conjecture

Is anyone here interested in the Collatz Conjecture? If so I believe I have the solution, seriously, and I need to work with someone who knows how to write a formal proof better than I. There are some errors in my proof, but the underlying principle is right. I only have my minors in mathematics, so my proof writing skills are subpar.

4. ## How can we slow down g?

I know exactly what I am doing: Trying to explain schoolboy physics to someone who is too arrogant to learn anything. Any object in orbit. It doesn't matter what coordinate system you use. It is still falling. The fact that you think changing the coordinates makes a difference is another illustration of how profoundly ignorant your are. Its not my choice. I haven't even reported it to the mods (your immaturity and ignorance is mildly amusing).

5. ## How does Mu-metal differ on a atomic level from soft iron

Field lines "prefer" to be in the high mu region but it's not attraction, per se. IIRC a bar of such material put in a uniform field would result in something that looks like a dipole. The domains align when there is an external field. The same thing is going on. A shield doesn't absorb the field - it doesn't disappear. The flux lines go into the shield, rather than through it. They exit the shield as well. The interior - the shielded region - has a substantially smaller field.

6. ## How do 4 fundamental interactions occur in nature naturally?

The (repulsive) electromagnetic force of the outer electrons in atoms is what keeps atoms apart and makes things appear solid (combined with other effects like the Pauli exclusion principle that give atoms their size). The strong force holds the nuclei of atoms together (and holds the quarks together in the protons and neutrons). That's about it, outside of extreme conditions such as neutron stars. The weak "force" (interaction) is responsible for some types of atomic decay, mainly beta decay and variants. The gravitational force holds planets, starts, solar system and galaxies together (and keeps you in your chair)

8. ## How are scientists able to see subatomic particles and define their intrinsic properties

The easiest is Cloud Chamber. https://en.wikipedia.org/wiki/Cloud_chamber If charged particle is flying through Cloud Chamber, there can be placed electrodes with uniform electric field, permanent magnet, or electromagnet, inside of the device. In external electric and/or magnetic field particle paths are bended. e.g. electron is attracted toward positive electrode, positron is attracted toward negative electrode. Electron has the same electric charge as pion-, muon-, or kaon-, positron has the same electric charge as pion+, muon+, or kaon+.. But their rest-masses are different.. So their traces look different in particle detector.. Same force applied to particles with different masses bends paths slightly differently, and they can be distinguished.

10. ## Confused about "antisemitism" in the Labour Party

No, I remember history books stating the Nazis had lost the war. They lost territory as a result; what would they keep ? I'm not sure where you're from, but who were the original ( or at least previous ) peoples who lived there ? Should you leave and give back the land ? I live in North America,. Do I have to leave and give back the land to the native Indians ? Do all non-aboriginal Australians have to leave ? Do all white Africans have to leave ? Why are you applying this bizarre 'morality' only to Israel ? I don't think you're anti-Semite, because intelligent/educated people are not. And I respect your opinion, because Israel does do some things which are distasteful ( and don't help their cause ), but to liken them to the second coming of Attila the Hun is hyperbole. Especially considering the character of the neighbors they have to defend againts.

12. ## If (illicit) drugs were legal.

John, I'm pretty certain you drink alcohol ( from previous conversations ) When are you gonna give it up and switch to doing heroin ? Do your (adult ? ) children drink ? Would you prefer they did heroin instead ? And, if not, why not ? ( since its side effects are so much more benign )

13. ## Can you believe in evolution and in god?

It's like a virus. Some get it worse than others. I know several people who don't really believe, and just "go with the flow" but they still indoctrinate their kids. Or agree to them being indoctrinated. And of course, going with the flow usually coincides with a mild level of indoctrination. The stronger the indoctrination, the stronger the beliefs. On average. That's why the Muzzies get their kids reciting the Koran over and over and learning it by heart. It works, and sticks for life.

14. ## If (illicit) drugs were legal.

Please explain how the molecule knows if it's being administered by a doctor. The point I have made several times is that most of the deaths attributed to illegal drugs are actually due to the fact that the drugs are illegal. There might be a quicker solution to this debate. Would you accept the opinion of a pharmaceutical chemist about the harm done by long term heroin use by addicts who can get hold of "clean" supplies (for example, doctors who are also users)?

15. ## Why doesn't the electron fall into the nucleus?

I'm really sorry about that late night rant, where I pressed 'submit' before engaging brain. It does, and I meant 'quoting only part of post', which is perfectly OK; I do that myself of course and sometimes don't quote a relevant part of the post, which I feel happened here - no bad intent by you. Inaccuracy by me again. You were, I thought rightly or wrongly, summarising my views in an inaccurate way and I should have said that or, better, nothing. Good we agree about tunnelling. Still apparently disagree here with you and others - precise terminology is a problem. I still maintain that per unit volume s orbital electrons are most likely to be found inside the nucleus. Since the orbital is much bigger than the nucleus that probability is still very low. Sorry again about my personal criticism, which was unjustified and should not have been posted. I've cancelled my downvote. Thank you for your excellent response.

16. ## Can you believe in evolution and in god?

Of course you can believe in both god and evolution. You can believe anything you want. You could believe that invisible goblins made the universe out of magic pixie dust. That's how belief works: It allows anything.

18. ## Can you believe in evolution and in god?

Well, if you want to keep moving the goalposts and making logically incoherent arguments, I'm out. Just a reminder of what you asked, as you seem to have forgotten: You have gone off on all sorts of tangents since then. As far as I can tell, just because you want yet another thread to display your ignorant bigotry. I think I'll just put you on ignore. You clearly have nothing useful to contribute.

19. ## Trump's Permanent Condemnations

Trump's ongoing feud Omarosa Manigault Newman is a good example of how meaningless either a compliment or a condemnation is from Trump. Prior to their most recent public escapade Trump had fired Omarosa from his reality show a couple different times and the fall out has always been scandalous including back stabbing and name calling. Omarosa is one of Trump's favorite protagonists. He involves her in all his public ventures just so there can be drama. I will honestly be shocked if she doesn't hit the campaign trail with Trump in 2020. A million dollars back in the 70"s is closer to 7 million today but it is more than that.He also had access to his old man's lawyers, accountants, advisers, fixers, and etc. A whole successful real estate infrastructure ready to go. Millions worth of logical support and services in addition to the cash he was given.

20. ## How can we slow down g?

That's even worse, since in a circular orbit (unchanging r) there must be an acceleration. You don't know which one, though.

22. ## Flood-related engineering...

The vest way to 'remedy a flood' is to use salt, or, a derivative of salt, maybe a new chemical, that sucks it up quickly? I figure this would take about a week, tops to get right. Then, in frequently flooded areas, they could have fire trucks that spew this stuff, or, those big road sweeping trucks dealing with the problem? Should take a week to get the chemicals right, or, less. I figure maybe some cation based natural stuffs... negative charge to attract the mass, into it?

24. ## If (illicit) drugs were legal.

So there is no difference between caffeine, alcohol, Cannabis, shrooms, LSD, Opiates, Peyote, Sage, and what ever you drink shoot snort or rub into your belly? Yeah one is a disgusting way to kill yourself the other kills orders of magnitude less but generally involves a needle... Some would disagree but I am with you on this as long as a non drug can be addictive....

27. ## Observer dependent reflective sciences

You can always just move on and let others choose to observe and comprehend without your inappropriate remarks. To say something is gibberish or trash is implying that everything has to pass and abide by your level of understanding for it to Merit an appropriate and constructive response. Its very primitive.

28. ## Trump's Permanent Condemnations

Ten Oz, I suggest you read the descriptions of Trump in the media and from the 'celebrities' if you want to know what smears I mean. Or are you saying that this is the first you have heard of Trump being smeared, insulted etc? You neglected to mention in your employment stats that there was a major adjustment by Obama in the way that the stats were measure when part time employment was lumped in with full time employment and given equal weight. ie a fudge. In any case the fact remains that employment really is up despite the claims that Trump would trash the economy. I have to admit to an error earlier. The Democrats did actually manage 100% black employment a while ago before their scheme was destroyed by a republican president (Abe Lincoln) You are desperate to play down Trumps success in DPRK. I guess it is all you can do. The fact is that Kim is already in ful control of DPRK and any progress we make there is a lot more than was achived by any previous administration. You seem to think that none of the problems you list even existed prior to 2016. Airbrush, As you well know Trump gets plenty of abuse. Why would you try to deny it? ODonnel calls him a traitor a racist and a pig so he responds in kind. What is the problem? You don't like it when someone pays back?? Misrepresented? One example from above - he was a self made bilionaire before he inherited anything. So why the need to misrepresent that fact? YOu have just done it again with your point 4. Trump was worth a billion when his dad died and left him 200M. You just cannot deal with the fact that someone you hate (despite not being able to tell us why) is also someone who is successful. So you seem to be saying that Trump is building on the 'success' of Obama? So what exactly did Obama do to create this 'success'? Was it by making energy more expensive? Was it all the extra government workers? Was it be making healthcare more expensive? Banning gas fracking? Giving money to Iran? What was it?? Fake news? What area? General? OK, the 'news' that Trump dumped all the carp food in the pond in Japan. That was memorable because apart from being false it showed that even the most trivial and unimportant detail is still going to be misrepresented by the media simply because they see that as their job. SO they have no credibility when it comes to more important stuff like the whole 'Russian Collusion' fiction. Two years and still not a shred of evidence! Once again John is desperate to convince himself of the inheritance story. Trump was loaned a million dollars and he turned it into a billion before his dad died. Putting it in a bank would NOT have delivered that return. Trump has not been bankrupt so that is another popular misrepresentation. Five of his businesses have failed. That is what happens sometimes. Given that he has started about 400 that is not a bad rate. In any case the smear is all that matters to you. The fact that you can tell me that a self made billionaire is not a financial success is just ridiculous and goes back to what I said earlier - some people are so deranged that they cannot accept simple facts. Trump is a billionaire and he did it himself, no matter how much you wish it were not so! The family of servicemen asked him to intervene. The fact that you have to misrepresent that is just beyond lame. And finally you try and tell us that the economy is doing nothing. Well, if it makes you happy to convince yourself then keep clinging to it.
