ekt_bear: Yeah, MCMC techniques supposedly are used a lot in physics. I wouldn't know the specifics though of where exactly they use it.

MCMC = Markov chain Monte carlo, right? I think it's mostly used in some kind of simulation studies.

I also discovered that statistical methods are used immensely in researches in some areas of physics. It means most of these computational courses like maths, stats, physics, comp sci, and ops research are kind of related or useful to each other.

ekt_bear: Sure. But I might use a toaster to make my breakfast. That doesn't mean that I am closely related to a chef, or something.

Everyone needs to know some computing nowadays. But that doesn't mean that they are defined by it, or that is their career.

Truely, u may be related to the chef, but i believe u're strongly related to the baker. Laffing!! Just kidding! Computational courses depend so much on computers for efficiency and to ease their work. I'm still wondering how they can perform large iterations and simulations without a computer.

I'm happy u guys are back. This is a nice thread i must say. The truth is that many computational courses like maths, physics, stats, ops research, etc are heavily dependent on computers today to carry out computations efficiently, therefore there is need for them to have some knowledge of computing.

PhysicsQED: The problem here is that you just don't know what you're talking about and want to argue blindly. This is becoming a waste of time. Later.

Hey man don't get angry now. We've been on this debate peacefully without any problems. We all argue to know more and to know better. I did'nt want to tell u this before; i'm enjoying this debate and i'm of course learning more from ur points. I' ve told u now, so let's go on.

PhysicsQED:

Statistics is still very much a branch of mathematics, please use Google to confirm.

[edited]

I've confirmed that long ago. U do. Google 'statistics', confirm and come back and edit ur post.

PhysicsQED: Is "quantum computing not the intersection between both fields" (physics and computer science)?

"Is computational physics not the intersection between both fields" (physics and computer science)?


You see how irrelevant your question is now?

if u want to tell us the relationship btw physics and CS pls do, but don't try to say statistics has no relationship with CS. In the university then, we had a lab equipped with computers for stats computing, but never had any computers in physics labs for computing. This should tell u something about who uses computer more in their work.

PhysicsQED: Statistics is a branch of pure mathematics. It's not inherently necessary for computing to be an integral part of it.

Sorry u're still living in the past. Statistics has stopped being a branch of mathematics. Statistics is a mathematical science that stands on its own now, and statistical computing is very significant to statisticians. Pls use 'google' to know more about this development.

ekt_bear: The statisticians I know do pretty simple stuff on the computer. PCA, regression/linear models, etc. Things that are prepackaged in statistical software.

They are no more programmers than a mechanical engineer who builds his models in matlab, or a chemical engineer who builds his models in mathematica is a programmer.

Being a consumer of software and writing the occasional small script doesn't make you a computer scientist.

No body said statisticians were computer scientists. We only said that the work of the statisticians require them to use computers. I just noticed u like PCA a lot. Have u ever used it in any research before? Is it really easy to implement PCA without a computer, especially when u have a high dimensional data, one with many variables?

okeyxyz: simply put: Any method/algorithm that handles large amounts of data is a statistical method/algorithm. So, what do computers do again??

Nice question bro.

PhysicsQED: No, this is totally incorrect. Please, not every algorithm is "statistical" merely by being an algorithm.

Did any body ever said so? We've always maintained 'statistical algorithm' and not just algorithm. And every statistical algorithm has to do with statistics.

PhysicsQED: No, this is totally incorrect. Please, not every algorithm is "statistical" merely by being an algorithm. The basis of, and the foundations of computer science lie in non-statistical pure math and logic while the basis of the actual physical computer (modern) is built on discoveries by physicists, but there are still some physicists that contributed to actual computer science significantly.

Always read well before u attack. No one is saying that statisticians built the first computer, No. One of the reasons for inventing computers and one of the first uses of computer was for handling and processing statistical data, Yes.

PhysicsQED: I think statistical computing might be what most people are thinking of when they were arguing that statistics and computer science were quite close/related.

what then have we been arguing about? And is statistical computing not the application of computer science in statistics? Is there not where the intersection btw both field is? Pls try and read more about statistical computing.

PhysicsQED: Statistics is a sub discipline of mathematics. Advanced theoretical statistics papers are pretty much as involved and complex as some other areas of math.

It is not necessary to know anything about programming or computer science to study statistics. The two fields are not that closely related.

Not in today's world of modern technology. U don't need to be a guru in programming or computer to study statistics, but u need knowledge of computer to be able to work as a statistician today. That is why computing is now an integral part of statistics.

De-Grace01:
l am back, your insinuation here shows that you dont believe in life after death, anyone who died in Christ is not dead but transitted to life after. l ask u again what happened in Mk 9:2- 13 is it a mistake. Moses and Elijah appeared to Jesus and prayed with him, for the dead brethren the life in fellowship continue.

Good response from the Bible bro.

TroGunn: True talk. Tithing is not for christians. It was part of the laws of Moses. It's now used by fraudulent pastors to fleece the ignorant. The laws of Moses is not for Christians, though informative - Eph 2:15. It's no mistake that tithing was not mentioned as being for Christians by Jesus or the Apostles. Christians are to give based on their heart - 2Corinthinas 9:7 (Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful.)

You are with us bro. Did the new testament say we should give 10%?? No. The emphasis in the new testament is 'Give' from ur heart and not under compulsion, for God loves a cheerful giver. The new testament emphasizes on 'Giving' and not 'Tithing'.

psoto: You've answered your question.

He knew the answer even before asking the question.

booqee: Well op follow ur heart. Beht sorry oh, i'm no fan of the catholic church. One tin i detest most about their doctrine is d way they give unnecessary honour to Mary...they rever her even more dan the Almighty. Wtf??

They are not unnecessary honours, she deserves such honours for being the earthly mother of Christ Jesus. Have u wondered why such honours are not given to Sarah, Martha, Mary Magdalene, Esther, Ruth, Hannah, Deborah, Dorcas, or Lydia? These are all God fearing women in the Bible.

joe4christ: Read your bible mal 3:8 Those who dont tithe are called rubbers, not even rubbing men but God and you think a rubber can enter God's place of rest?
Do you think the tithe goes to God or maybe God is in need of it for his personal use of course not but when you dont tithe u hinder God's work on earth, have u forgotten the bible says in mal 3:10 that we should bring ye all the tithe into his house (church) that there might be enough in his house (church) and have you forgotten the bible says a worker deserves his wages? So how can pastors be paid when we refuse to pay our tithe, we acknowledge God being our source in words but not ready to obey his command in malachi 3:10 is'nt that robbing God?
Now you tell me how a robber would inherit the kingdom of God talk more of someone who is robbing God. Think again bro!

Malachi? I can't find that in my new testament Bible bro. Are u sure the prophecies of Malachi were for christians? What about the laws of Moses? Why are they not important for christians to observe and keep? Why won't christians keep the sabbath day (saturday) holy?

frosbel: Fa fa Foul !!

Tithing is out of the equation. Tithing is not a condition for salvation, never was and never will be .

Yes, u're correct. That's why the Apostle Paul did not emphasize on it. It's a jewish law and doctrine, and not for christians.

souldust: from where did they get their legitimacy to be called mid belt youth? I doubt if such an oganization exists.

Northern protectorate and southern protectorate existed before the british amalgamated the 2 together in 1914. The middle belt has always been in the north even before the amalgamation, which makes them northerners. No body decieved no body in fighting somebody. Are they now saying that the hausa & fulani people are more sensible than them? Why would they claim that they were decieved? If really they were then it means the hausas could still use another method to decieve them again; or may be this time around they could be decieved by the igbos to fight the hausas and fulanis. It's rather late.

ekt_bear: In nigeria perhaps. But elsewhere, this is not the case

No, every where in the world statistical concepts are the same. Statistics and computing are very closely related, even in the US. Statisticians cannot work today without good computing skills. U can find out about what it takes to be a Statistician in America from the American Statistical Association (ASA) website.

Olanlere11: There were indications on Monday that crisis might have engulfed the Northern Christian Association of Nigerian over the call on President Goodluck Jonathan to resign.

The assocation had on Sunday called on the President to resign for   saying he could not crush the Islamic sect, Boko Haram. The president reportedly said, “They are our siblings and you cannot set the army to wipe out your family”.

The Northern CAN had expressed shock and disbelief at the President’s statement despite that the sect had killed several innocent Nigerians, particularly Christians, wondering why his administration could not descend on the sect.

The spokesman for the body, Mr. Sunday Oibe, had said, “Jonathan has failed us Christians, he has failed Nigerians and he should resign as president because by this statement, it is very clear that he is not capable of handling the danger posed by the Boko Haram insurgency.”

Our correspondent learnt that the Northern CAN spokesman had come under fire over the statement credited to him.

A source within the leadership of the organisation, who would not want his names in print, told our correspondent on the telephone that “when I called the young man, he said he didn’t  mean that our president should resign. We in the Northern CAN would not want to do anything that will cause crisis for President Goodluck Jonathan.”

However,  Special Adviser to Governor Patrick Yakowa of Kaduna State on Religious Matters, Reverend Joseph Hayab, on Monday warned religious leaders across the country against overheating the nation’s polity with inflammatory statement that could cause disaffection in the country.

Hayab, in  a statement in Kaduna on Monday, said the statement urging the President to resign was capable of inciting  “Northerners and especially Christians against the Jonathan Administration,” warning that religious leaders must not overheat the Nigerian polity.

The governor’s aide, a former Secretary-General of the Kaduna  CAN, said, as a former Secretary  of CAN  Kaduna State and  also a former PRO of CAN 19 Northern states and the Federal Capital Territory, added, “Northern CAN has no quarrel with the statement from President Jonathan that it would not be the preference of the Federal Government to send in soldiers to wipe out Boko Haram for the simple reason that Boko Haram are faceless and when soldiers are sent in to wipe out a faceless group it is the innocent that suffers.”

The president too should learn how to say things that are not provoking.

hisblud: reading the bolded again, i see propaganda rhetorics. So now civilians meeting, meet with guns and when police come to check, they open fire Oh we are in US where "civilians" meet wit guns? And for him acknowledging there was a shoot out, it means something occured.

You just said my mind.

ekt_bear: There is a very generic between statistics and computing, in that most statistics is done on a computer. But statisticians aren't familiar with the same concepts one would expect from a CS graduate.

Statistics graduates are not CS graduates, but they know well that their basic tool for handling data is a computer; and they also know very well that they need to be familiar with the computer to be able to work successfully with it. Statistics and computing are inseperable bro!.

ekt_bear: Haha not the ones I know.

They are pretty meh programmers.

Haven't you noticed how ugly their main data analysis tool (R) is?

I'm not sold on statisticians naturally having some affinity for programming

Atleast now u're saying the truth for once that there is a correlation btw statistics and computing. Why condemning R? R was developed by students for students' use and not for commercial. Why didn't u also condemn SAS and STATA?

ekt_bear: And not too many develop new statistical algorithms. Just reuse known stuff. E.g., run PCA on such-and-such dataset.

Yes, u're right; just the same way that only very few CS graduates can write functional algorithms and develop any software.

ekt_bear: Ok. Maybe in Nigeria the majors are similar. But in my experience, in the US they are not.

Most stat students I know aren't very good at programming, for example. Don't know much about algorithms and data structures. Etc.

Not to say that physicists know these things either.

Basically, in my experience, they are three pretty separate and distinct courses of study (at least in the US)

You also need to know that most statisticians are good programmers who spend most of their time developing, testing, and implementing statistical algorithms and crafting their own statistical software packages.

Why are they blasting Asari Dokubo? Is he not a follower of their islam again?

Pls let them start it immediately oh, else we will help them by boycotting buying their beef from those their tse-tse fly infested cows. We can begin to import beef from Canada and America if we need beef. They cannot threaten people.

okeyxyz: Exactly. @PhysicQED is probably mistaking computer engineering for computer science. Even the word computer/computing indicate processing or calculating data/ratios, which is precisely what statistics does. Every database is handled by statistical algorithms.

Don't mind him. He ought to know that computers were built by mathematicians to handle statistical data, especially census data. Today, many statisticians are involved in the development and implementation of statistical algorithms that can carryout complex statistical analysis, and they do this in collaboration with computer scientists. That should tell anyone that there is a strong relationship between stats and CS.

PhysicsQED: Ironic that statistics is seen as being closer to computer science than physics when there are a whole slew of physics Ph.Ds that turned to computer science and became prominent in it and some physicists were involved in creating the first computers.

@ ekt bear

I'm pretty sure statistics in the U.S. is basically pure math with a specialization and programming is optional, and for computer science degrees, statistics based courses are optional, but in Nigeria and/or the UK the setup is different, hence the perception that statistics is closer to computer science there.

Why did u forget to mention that the first computers were built to handle and solve statistical algorithms?
