The Hamiltonian is an operator representing the total energy of the system. To get the total energy of the system all you have to do is compute the EXPECTATION VALUE of the Hamiltonian. This computed value is basically your total energy. Computing expectation value is trivial - if you need help I can show you.

Wow thanks. I hope to vibrate at your own frequency very soon with your help.

Hehehe nobody one carry last I plan to do it in masters though that's if it doesn't make me mad.

Suppose you know that- OF WHAT POSSIBLE USE can that Knowledge be to you?

How could you apply that Knowledge in a USEFUL way that benefits the Average man- not ACADEMICS, who get PAID for juggling MYTHOLOGICAL IDEAS about things ordinary people can NEVER see, nor experience their whole life?

if everybody had that mindset we would not be where we are in science. Just go to YouTube and watch videos on quantum mechanics your perceptions will change have u ever imagined what it would be like if human beings could behave like waves.

Although this branch of physics is a vast ocean,will want to contribute a drop into it hoping it will enlighten readers and lovers of physics

Want to be brief as possible so lemme start
quick intro
In the early twentieth century sometimes around 1925 a new theory burst into existence. With dizzying, almost meteoric speed, this theory overthrew long-cherished notions about matter that had been held since the time of the Greeks. Almost effortlessly, it vanquished scores of long-standing fundamental problems that had stumped physicists for centuries. What is matter made of? What holds it together? Why does it come in an infinite variety of forms, such as gases, metals, rocks, liquids,
crystals, ceramics, glasses, lightning bolts, stars, and so on?

The new theory was christened quantum mechanics, and gave us the first comprehensive formulation with which to pry open the secrets of the atom. The subatomic world, once a forbidden realm for physicists, now began to spill its secrets into the open.

To understand the speed with which this revolution demolished its rivals, we note that in the early 1920s some scientists still held serious reservations about the existence of "atoms." What couldn't be seen or measured directly in the laboratory, they scoffed, didn't exist. But by 1925 and 1926, Erwin Schrodinger, Werner Heisenberg, and max born had been developed an almost complete mathematical description of the hydrogen atom. With devastating precision, they could now explain nearly all the properties of the hydrogen atom from pure mathematics. By 1930, quantum physicists such as Paul A. M. Dirac were declaring that all of chemistry could be derived from first principles. They even made the brash claim that, given enough time on a calculating machine, they could predict all the chemical properties of matter found in the universe. To them, chemistry would no longer be a fundamental science. From now on, it would be "applied physics"

Fairly rapidly, quantum theory began to give us a comprehensive framework in which to describe the visible universe: The material universe consists of atoms and its constituents. There are about 100 different types of atoms, or elements, out of which we can build all the known forms of matter found on earth and even in outer space. Atoms, in turn, consist of electrons orbiting around nuclei, which in turn are composed of neutrons and protons. In essence, the key differences concepts of quantum theory can now be summarized as follows------**

Oops before that let's give a formal definition of quantum physics

what us quantum physics?
Simply put it is the description of the behaviour of matter and light on an atomic scale(smale scale)---hence the difference between quantum physics and Einstein's relativity

now the key concepts of quantum physicd
1-Forces are created by the exchange of discrete packets of energy, called quanta--meaning ?

In quantum theory light was to be chopped up into tiny pieces. These packets of light were named photons, and they behave very much like point particles. When two electrons bump into each other, they repel each other not because of the curvature of space, but because they exchange a packet of energy, the photon.
The energy of these photon measured in units of something called Planck's constant (6.626 x10*34js)
The almost infinitesimal size of Planck's constant means that quantum theory gives tiny corrections to Newton's laws. These are called quantum corrections, and can be neglected when describing our familiar, macroscopic world. That is why we can, for the most part, forget about quantum theory when describing everyday phenomena. However, when dealing with the microscopic sub-atomic world
these quantum corrections begin to dominate any physical process, accounting for the bizarre, counterintuitive properties of subatomic particles

2Different forces are caused by the exchange of different quanta.

Lemme explain--we have the weak the strong the electromagnetic and gravitation force,and the 2nd theory is trying to explain how this forces are caused. Now this is how they are caused

- weak force, is caused by the exchange of a different type of quantum, called a W particle (W stands for "weak" the strong force holding the protons and neutrons together within the nucleus of the atom is caused by the exchange of subatomic particles called pi mesons

Both W bosons and pi mesons have been seen experimentally in the debris of atom smashers, thereby verifying the fundamental correctness of this approach. And finally, the subnuclear force holding the protons and neutrons and even the pi mesons together are called gluons

In this way, we have a new "unifying principle" for the laws of physics. We can unite the laws of electromagnetism, the weak force, and the strong force by postulating a variety of different quanta that mediate them. Three of the four forces (excluding gravity) are therefore united by quantum theory

OK let's take a short break,,hunger is knocking
3rd and 4th theory on their way..

Can quantum mechanics be used to know the position of an orbital in an atom

benji93:
you are wrong," is there any experimental proof that an electron could be in a box and outside a box at the same time", you missed the point, i used the word "simultaneously", this phenomenon described above does not mean quantum tunnelling,quantum tunnelling is the process by which quantum objects including atoms pass through barriers,especially when a barrier initially reflective is made thinner.
2.Yet again you are assuming a stationary electron cannot be charged, which is the same as assuming tht a stationary proton cannot be charged. If you agree that electrons are charged.
3.What is a magnetic force? Basically F=Bqvsin(theta)(v=velocity), so an electron does not have to be accelerating to be affected by a magnetic force, and y would the constant velocity electron be affected by a force, if it does not exert such a force itself?so a constant velocity electron must be producing a magnetic field itself, well it will accelerate due to the external force, but this is only because, it has a tendency to accelerate or accelerate another entity by virtue of the force field.Before the electron moves it accelerates from rest,thts fine, but this time i am talking about the state by which it is moving at a constant velocity.I repeat again, you need to reevaluate ur knowledge bro,its a fact that electromagnetic radiations are emitted by accelerating charges,this does not mean non-accelerating charges to not produce electromagnetic fields-an electromagnetic radiation implies an electromagnetic field, but the reverse is not true. because by virtue of the aforementioned, electrons moving at a constant velocity should produce both electric and magnetic fields. Now let me refer you to an argument tht will help us tread on the same lane.How is an electromagnetic radiation produced, you might say an accelerating charge.But literally and deeply electromagnetic waves are produced by oscillating electric and magnetic field, this oscillation implies, there is a change in electric and magnetic field, so we can thus say an accelerating charge can produce an electromagnetic wave(sometimes it does not).But we are talking about changing electric and magnetic fields here not the presence of electric and magnetic field itself.The electromagnetic field can be present but not changing,so an electron moving at constant velocity can produce an electromagnetic field but not a changing electromagnetic field, hence no radiation of electromagnetic waves.
summary
i.the electric field produced by the electron is intrinsic, regardless of whether it is moving or being at rest.
ii.a magnetic field is produced by an electron in motion, be it uniform or non-uniform,that is explainable by the expression F=Bqvsin(theta).So a stationary electron cannot produce a magnetic field, by virtue of the expression
iii.an electromagnagnetic radiation is produced by a changing electric and magnetic field.
You need to have an open mind bro.So tell me why you think an electromagnetic field is only produced by an accelerating charge(electron)

guys please

AkinPhysicist:
1. Guy- you don't know what you are talking about. Quantum Tunneling was confirmed decades ago. It is one of the experimental corner stones of quantum physics.You still do not understand double-slit experiment - please go back and re-learn it. The fact is an electron behaves both as a particle (photo-electric effect) and as a wave (double-slit experiment).

2.As long as you are not disputing this fact, then we are good.

3.You don't understand Electromagnetic fields. Go and re-learn it. EM fields are generated by accelerating charges - no such thing as the mysterious ambient/intrinsic EM field you seem to be suggesting. Please go and re-learn this basic stuff.

guys please just help me find an easy way of deriving equation for total energy using Hamiltonian operator

yoged:
Did quantum chemistry in Unilorin when I was in 300L, Taken by Dr rabinowitch and Dr eke Now a professor. I just hate this damn topics. It's like magic To me plus the 2 lecturers makes it so boring. All those Schrodinger equation. And So many annoying signS. Ended up having D. (46) Omo I thank My God. Alot of people dey carry the course

D? how did u do it studying it 400 level I can easily derive Schrödinger wave equation but that equation for total energy is using Hamiltonian operator is a dead end for me

muslims always pretending, u hate anytin westerner but yet u put on cloth,shoes that were made by westerners even the bombs and other ammunition u use to inflate terror on people were made by westerners.

No mind them the highest number of paedophiles are Muslims and even Mohammed was a paedophile

Muslim school students staged a protest against Valentine’s Day on Monday, denouncing what they said was a Western celebration that encourages casual sex.
“Say no to Valentine!” chanted the students, who were aged between 13 and 15 and included many girls wearing headscarves.
It was the latest expression of anger at Valentine’s Day in the world’s most populous Indonesian Muslim-majority country, where Islamic clerics and some pious Muslims typically use the occasion to target what they see as Western decadence.
“This protest was organised as we have seen on television that Valentine’s Day tends to be associated with free sex,” said Pandu Satria, organiser of the demonstration that was attended by scores of students. “That makes us afraid.”
Ida Indahwati Waliulu, headmaster of the school which is run by an Islamic organisation, added: “There is a certain pride about this positive action carried out by the students.”


Several cities across the country also banned people from celebrating the occasion.

In neighbouring Malaysia, which is also a muslim-majority country, a group called The National Muslim Youth Association urged females to avoid using emoticons and an excessive amount of fragrance in a pre-Valentine’s Day message.


The group also set out guidelines about how people could reject the annual celebration of romance by making anti-Valentine posters and not wearing Valentine-themed outfits.

Noah La'Cap and his father

Student gets early graduation ceremony so dying dad can watch

By Madeline Holcombe, CNN

(CNN) — His son's high school graduation was a day Alfred La'Cap had been looking forward to — and one he didn't think he would get to see.


La'Cap, 69, has terminal prostate cancer with a dire prognosis: He's unlikely to make it to May.


So administrators at Long Beach High School in Mississippi stepped in and held a graduation ceremony three months early.

"Considering the circumstances, I felt like if we can bring a little joy to a family, then we're happy to do that," Principal Larry Ramsey told CNN affiliate WLOX .


The ceremony, held over the weekend in the family driveway, was a small, bittersweet one.
La'Cap's son, Noah, was dressed in a red cap and gown and sat next to his father. Someone played "Pomp and Circumstance" on a cellphone. Family members dabbed their eyes.

When the time came, Noah La'Cap tossed his mortar board and then placed it on his dad's lap.
He told the station the family has come to terms with their difficult reality. He has accepted his father won't be around to see him graduate college, start his first job, get married.

"There's been times where I couldn't focus on school because I was thinking about him all the time, but I persevered because I'm supposed to graduate for him," Noah La'Cap said.
And he did.

Valid points but there are more single guys just that they hiding due to harsh economic situation. Who wants to be a liability father?

The truth is their are more ladies than guys in Nigeria, that translates into having more ladies than guys and it would get worse as the Bible has already prophesied that it would be one man and seven ladies at a point in time

Secondly, why do u use GEJ as a standard for morality in this APC government since you acknowledge he is so corrupt.

BUHARI'S GOVERNMENT IS A MEGA DISAPPOINTMENT


ESPECIALLY TO MANY OF US THAT DONATED HEAVILY IN BOTH HUMAN AND MATERIAL RESOURCES.




MY FINANCIAL CONTRIBUTIONS TO HIS CAMPAIGN WOULD AV MADE MANY POOR WIDOWS IN MY VILLAGE VERY HAPPY. BUT I WAS THINKING THAT I WAS MAKING CONTRIBUTIONS TOWARDS A BETTER GOVT THAT WILL BETTER THE LIFE OF ALL OF US.

NOW I KNOW MY ASSUMPTIONS WAS IN ERROR.


I FULLY UNDERSTAND THAT APC OR SHOULD I SAY BUHARI IS LIKE MMM AND LIKE MANY MMM VICTIM - I HAVE COUNT MY LOSSES AND MOVED ON.

























BUT WHAT I STILL DON'T UNDERSTAND IS HOW THE IGBO LEADERS WAKE UP NOW TO SUPPORT A FAILING GOVERNMENT AFTER EVERY ONE HAS SEEN THE WRITING ON THE WALL AND ARE ABANDONING SHIP!


ARE THE SO-CALLED IGBO LEADERS DUMB OR STVPID OR BOTH?

They have no political relevance in south east.

Mehn Igbo's are wonderful just imagining what would happen if we had our own country.



N.B Am not belittling any tribe o.

tollyboy5:
I can't believe some Igbo could be so myopic and stupid in reasoning. you are the reason why you won't succeed nothing is good to your type. don't worry 2baba is nau Yoruba man maybe if we all insulted him and refuse to join the protest this same stupid people from Jupiter will come and point fingers . just watch the protest before moving back to your planet or better still watch it from satellite then you'll know we civilised people not illiterate

I think Igbo's have more experience than tuface in protest, better wear a bullet proof vest cos police will just implant some miscreants to cause trouble in the crowd And then start shooting.
