In an interlude, Eugene entered the ring and shared his excitement about being at his first WrestleMania with the crowd in attendance.
While attempting to recall his favorite WrestleMania moments, Muhammad Hassan and Daivari interrupted him with Hassan expressing his outrage for not being included in a match for the event.
Hassan concluded that since he was not scheduled to compete at the event and was therefore denied the opportunity to experience his own WrestleMania "moment", he would have to create a "moment" of his own.
Following this remark, Hassan and Daivary began to assault Eugene.
With Eugene placed into a Camel clutch hold while Daivari verbally attacked him, Hulk Hogan came down to the ring to save Eugene from the assault, knocking Hassan and Daivary out of the ring.

Orton then attempted to use Undertaker's own finishing maneuver against him with the Tombstone piledriver, however, it was reversed by Undertaker into Tombstone piledriver of his own which led to the definitive pin fall.
The Undertaker won the match and continued his undefeated streak at WrestleMania with a 13-0 record.
The next match was for the WWE Women's Championship, between Trish Stratus and Christy Hemme with Lita at ringside.
Stratus controlled most of the match though Hemme attempted many pinning maneuvers that were unsuccessful.

Autofocus is a procedure for finding the correct position of the lens for a scene.
The autofocus feature can be provided in a system which includes a movable optical element, a motor, an image sensor and a processing unit.
The autofocus procedure is done by changing the lense position and image quality measurements in each position.
The position that provides the image with the best quality will be used as the best focus.
The image quality may be estimated using image gradients.
To speed-up the autofocus procedure, the autofocus is done in two steps: the first run over the full range of the lenses movement with a significant step will provide the estimated position which will be improved in the second run over the small range with a small step.
Interpolation between the few best positions may improve the results accuracy.

Jugiong is a small village on the bank of the Murrumbidgee River in New South Wales, Australia.
It is 344 km south west of Sydney on the Hume Highway.
The first people to live in the area were indigenous Australians, the Wiradjuri people.
The first Europeans were the explorers Hamilton Hume and William Hovell on their trip in 1824.
Henry O'Brien, an Irishman, started farming sheep in 1825.
His farm, called the Jugiong Run, was 125,000 acres.
Explorer Charles Sturt reached the Murrumbidgee at Jugiong in 1829 at the start of his travels down the river.
In 1845 another Irishman named John Philip Sheahan (1816–December 9, 1877) built the Sir George Tavern (an hotel) which made Jugiong an important resting place on the new road, the Great Southern Road, to Melbourne.
The building was destroyed in a flood in 1852.
The flood also destroyed the buildings at the town of Gundagai.
Sheahan rebuilt the hotel with walls up to 500 mm thick and it is still in use; remaining in the family throughout the preceding years.
It is the oldest family owned hotel in Australia.
The first blocks of land at Jugiong were sold at auction in 1853.
Three years later a post office was opened.
In 1858 a police station was built, and work started on a catholic church, St.John the Evangelist.
About 120 people were living at Jugiong by 1862.
An Anglican church was started in 1872.
The Jugiong Public  school opened in 1883 with 56 students.
Australian cricket player Richie Benaud started his schooling at Jugiong in 1935.
On 15 November 1864  bushrangers (thieves) stopped all traffic including the mail stagecoach (a cart pulled by horses) 5 km south of Jugiong.
Over 60 people were stopped by the bushrangers.
They wanted to steal (take with force) gold, money and other valuables.
The bushrangers were Ben Hall, John Gilbert and John Dunn.
In the attack one policeman, Sergeant Edmund Parry was shot dead by John Gilbert.
A song called The Road to Jugiong  with words by Robert John Cassidy (1880–1948) and music by James A.Steele was published by Allans, Melbourne, in 1940.
In 1995, the new Hume Freeway, went around the village.
In 1996 a new rest and picnic area was built to help travelers take a break on their journey.
Facilities at Jugiong include:
a cafe, the Long Track Pantry Cafe ,
a motel
a wine shop
a fruit and vegetable shop
a petrol station

The Egerton Gospel is a set of papyri that are now in the British Museum.
The papyri have been dated to the second century.
The text they contain may have been written 50-100 AD.
It is one of the oldest known fragments of any gospel, or any codex.
Soon after the British Museum acquired it in the summer of 1934, it was printed in 1935.
It is also called the Unknown Gospel, as no ancient source makes reference to it, in addition to being entirely unknown before its publication.

The Gospel of Thomas (or the Gospel according to Thomas, Coptic: p.euaggelion p.kata.cwmas) is a text written during the era of the New Testament.
It is considered to be an apocryphon.
It was found in Nag Hammadi, Egypt in 1945.
The text is in the form of a codex, bound in what today is known as Coptic binding.
It is almost complete.
Unlike the other texts, it is not a narrative, but a collection of sayings and short dialogues attributed to Jesus.
There are 114 sayings in the text.
Most are compatible with the other gospels.
They can also be found in one of the other gospels.
Some were unknown to scholars before the codex was found.
None of the big Christian groups accepts the Gospel of Thomas as canon.

Rubik's Cube is a puzzle cube, and the world's biggest selling toy of all time with over 300,000,000 (300 million) sold.
It was invented in 1974 by Hungarian sculptor and professor of architecture Ernő Rubik.
In a classic Rubik's Cube, each of the six faces is covered by nine stickers, each of one of six solid colours: white, red, blue, orange, green, and yellow.
In currently sold models, white is opposite yellow, blue is opposite green, orange is opposite red, and some might replace blue with black or purple.
Types of Cubes
The standard Rubik's Cube is 3x3x3.
3 blocks across, 3 blocks down, and 3 blocks deep.
Cubes can be made in 2x2, 4x4, or larger versions.
the largest cube is 33 x 33, which is also 3d printed.
Cuboids are cubes with uneven sides.
Some options are the 3x2x2 or 3x5 or 4x3.
Some cuboids can shapeshift or jumble.
That means the cube goes out of its original shape.
To solve a shapeshifting cube it must return to the original shape before it is considered solved.
A Rubik's Cube is a cube split into a number of smaller cubes with different colored faces attached to a rotating piece of metal in the middle.
Total, there are 26 small cubes.
The Rubik's Cube have six sides with 9 little cubes attached to it and each side has one color: red, yellow, blue, orange, white and green are the most common colors.
The cubes can be rotated and twisted along rows and faces.
The aim of the puzzle is to make each face of the cube have the same color.
Solving a Rubik's Cube requires logic and thinking.
There are many different ways to learn how to solve a Rubik's cube.
There are many methods that people use to solve a Rubik's Cube.
Today the most common one is called CFOP, also called Fridrich Method, named after the popularizer Jessica Fridrich.
In this method first the white cross is solved, then F2L(First 2 Layers) followed by OLL(Orientation of the Last Layer) and PLL(Permutation of the Last Layer).
Other methods include Petrus,  ZZ, Roux, Keyhole and others.
The record for one Rubik's Cube solve is 3.47 seconds by Yusheng Du at the Wuhu Open 2018 (in China).
Ruihang Xu holds the record for the average of 5, which is 5.48 seconds, set at the Wuhan Open 2021 In China.
The record for the fastest robot to solve a cube is 0.38 seconds!

The flag of Scotland is a white X-shaped cross (a saltire), which represents the cross of the patron saint of Scotland, Saint Andrew on a blue sky.
The flag is called Saint Andrew's Cross or the Saltire.
According to legend, in 832 A.D. King Óengus (II) (or King Angus) led the Picts and Scots in battle against the Angles near modern-day Athelstaneford in East Lothian.
King Angus and his men were surrounded and he prayed for deliverance.
During the night Saint Andrew, who was martyred on a saltire cross, appeared to Angus and assured him of victory.
On the following morning a white saltire against the background of a blue sky appeared to both sides.
The Picts and Scots were heartened by this, but the Angles lost confidence and were defeated.
According to the legend, this saltire design has been the Scottish flag ever since.
Material evidence of the saltire's use dates from many centuries later.
In 1385 the Parliament of Scotland decreed that Scottish soldiers should wear a saltire as a distinguishing mark.
The earliest surviving Scottish flag consisting solely of the saltire dates from 1503: a white cross on a red background.
By 1540 the legend of King Angus had been altered to include the vision of the cross against a blue sky.
Thereafter, this saltire design in its present form became the national flag of Scotland.
Flying the flag
There are five flagpoles outside the Scottish Parliament Building in Edinburgh.
The flag of Scotland is flown every day, alongside the Union Flag and the flag of Europe.
The fourth flagpole is used for special occasions such as Commonwealth Day and United Nations Day.
The fifth pole is used for the Royal Standard of Scotland.
Edinburgh Castle is managed by Historic Scotland, and has a military garrison of the British Army.
Like all British Army bases, it flies the Union Flag (in ratio3:5) and the Army flies it every day from the Clock Tower.
The Saltire is flown every day at the Half Moon Battery.
The flying of the Union Flag at Edinburgh Castle has sometimes caused controversy.
In 2001, a group of 20 Scottish National Party MSPs called for the Union Flag to be replaced by the Saltire.
The Scottish Government has decreed that the flag of Scotland will fly on all its buildings every day from 8 am until sunset.
These days are the same as the flag days of the United Kingdom with the exception of 3 September (Merchant Navy Day), which is a specific flag day in Scotland and during which the Red Ensign may also be used.
Another difference with the rest of the UK's days is that on Saint Andrew's Day, the Union Flag will only be flown if the building has more than one flagpole – the Saltire will not be lowered to make way for the Union Flag if there is only one flagpole.
This difference arose after Members of the Scottish Parliament complained that Scotland was the only country in the world that could not fly its national flag on its national day.
The flag can be flown at any time by any individual, company, local authority, hospital or school.
There is no need to get consent to fly the flag from a vertical flagpole.
The flagpole itself may need planning permission.
Most local authorities in Scotland fly the Saltire.
Glasgow City Council fly the flag from the City Chambers building in George Square, while the City of Edinburgh Council fly the flag from their own city chambers.
In 2007 Angus Council led by Robert Myles decided to change the Saltire for a new Angus flag.
This move led to public outcry across Scotland with more than 7,000 people signing a petition opposing the council's move, leading to a compromise whereby the Angus flag would not replace but be flown alongside the Saltire on Council buildings.
Colour and dimensions
At various times throughout history colours as light as sky blue or as dark as dark navy blue have been used (a selection apparently motivated by which colour of blue dye was available at the time).
When incorporated as part of the Union Flag, the navy blue colour used was that of the Blue ensign belonging to the historic 'Blue Squadron' of the British Royal Navy.
Dark blue was primarily used for reasons of expediency—it suffered less from the effects of fading resulting from prolonged exposure to the elements (namely sunlight and salt spray).
Although this navy blue colour was used specifically for depicting the Union Flag on maritime flags on the basis of durability, it soon became standard on Union Flags, both on land and at sea.
This navy blue colour trend was adopted for the Saltire itself by many flag manufacturers, resulting in a variety of shades of blue being depicted on the flag of Scotland ranging from "sky blue" to "royal blue" to "navy blue".
Eventually, this situation resulted in calls to standardise the colour of Scotland's national flag.
In 2003, a committee of the Scottish Parliament met to examine a petition that the Scottish Government adopt the Pantone 300 colour as a standard. (
Note that this blue is of a lighter shade than the Pantone 280 of the Union Flag).
Having taken advice from a number of sources including the office of the Lord Lyon King of Arms, the committee recommended that the optimum shade of blue for the Saltire should be Pantone 300 (that is, 0, 101, 189 in the RGB colour model, or #0065BD as hexadecimal web colours).
Recent versions of the Saltire have therefore largely converged on this official recommendation, though dark blue has continued in use.
The flag's proportion is not fixed, but is generally taken as 1:2, 2:3, 3:5 or 4:5.
The bars in the cross should be 1/5 (i.e., 20%) the width of the flag.
Outside Scotland
Inverse representations (blue saltire on a white field) of the Scottish Saltire are also used outside Scotland.
In Canada, an inverse representation of the Saltire, combined with the shield from the Royal Arms of the Kingdom of Scotland, forms the modern flag of the Canadian Province of Nova Scotia, the first colonial venture of the Kingdom of Scotland into the Americas.
In Russia, during the period before and after the Soviet Union, the naval ensign of the Russian Navy has been an inverse representation of the Cross of Saint Andrew. (
Saint Andrew is also a patron saint of Russia).
The very same Saltire was also flown as the flag of Galicia in Spain until 1891, when Russia requested the Galician flag to be modified in order to avoid confusion between Galician ships and Russian Navy ships.
The current Galician flag is actually the original blue-over-white saltire but without one of the arms of the cross.
The U.S. state of Alabama's flag is officially "a crimson cross of St. Andrew on a field of white," but the reference is used only to describe the shape without using the vexillological term saltire as that flag's origins are from either or both of the Confederate Battle Flag or the Cross of Burgundy Flag, both of which have saltires and are associated with the history of that state.
Similarly, the Spanish island of Tenerife and the remote Colombian islands of San Andrés and Providencia also use the saltire on their flags.
The Scottish Saltire is also used unofficially by students and graduates of Xavier University because of the university's blue and white official colors and the resemblance of the flag to the letter "X".
It is also the flag for St. Andrew's Scots School, Argentina (founded in 1838) and its "spinoff" university Universidad de San Andrés.
Incorporation into the Union Flag
The Scottish Saltire and field is one of the key components of the Union Flag.
The Union Flag has been used in a variety of forms since 1606, when the flags of the Kingdom of Scotland and Kingdom of England were first merged to symbolise the Union of the Crowns. (
The Union of the Crowns having occurred in 1603.)
In Scotland, and in particular on Scottish vessels at sea, historical evidence suggests that a separate design of Union Flag was sometimes flown to that used in England.
Following the Acts of Union of 1707, which united the Kingdom of Scotland and the Kingdom of England, the standard Union Flag became the national flag of the new United Kingdom of Great Britain.
From 1801, in order to symbolise the union of the Kingdom of Great Britain with the Kingdom of Ireland, a new design was adopted for the Union Flag of the United Kingdom of Great Britain and Ireland.
The 1801 design did not change with the partition of Ireland in 1921 and creation of the Irish Free State, and is the flag of the United Kingdom of Great Britain and Northern Ireland today.
The Royal Standard of the King of Scots, also known as the Royal Flag of Scotland or the Lion Rampant, is the flag used historically by the King of Scots.
It remains the personal banner of the monarch and use of this flag is restricted under the Act of the Parliament of Scotland 1672 cap.

It can make pictures of atoms on a surface and move the atoms to different places.
It was invented by Gerd Binnig and Heinrich Rohrer in 1981 at IBM, in Zürich.
In 1986 they won the Nobel Prize in Physics for inventing it.
The STM is called a microscope because it makes pictures of tiny objects.
But it is different -- it doesn't have anything to look into with our eyes.
It is similar to feeling the shape of objects on a table in a dark room: you can draw a picture of the shape even though you did not seen it with your eyes.
The STM does this for very tiny objects.
It works by scanning a sharp metal needle back and forth across a surface, and uses electric current instead of force to sense the shape.
When the tip of sharp metal needle is brought very close to the surface of a thing being studied, a voltage between the two causes electrons to flow through the space between them.
The electrons cross this space by a process called quantum tunneling, which gives the STM its name.
This tiny current of electrons flows when the tip is almost touching the surface.
The current changes as the probe moves along the surface.
This change is recorded by a computer, which makes it into a picture that we can see.
The surface and the tip must conduct electrons, so they must be made of a metal or semiconductor.
A related kind of microscope senses the force instead of the electric current.
This kind of microscope is called an atomic force microscope.
STM is a hard thing to do, because it needs a very clean surface and a very sharp needle tip.
The STM usually works in a vacuum to keep the air molecules from disturbing the surface, but it can also work in air or water.
Ways it can make a picture
First, the tip is brought very close to the surface of thing being studied.
This distance is about half of a nanometer.
Then the tip is moved very carefully back and forth across the surface.
The electrical current is measured while the tip is moved back and forth (constant height method).
The STM can also work by adjusting the tip so the tunnel current stays the same (constant current method).
Using the constant-height method is faster.
Using constant-current method helps avoid bumping the tip into things on the surface, so it can study things that are rougher.
Moving atoms
The STM can move an atom (or a molecule) to a new place on the surface.
To move an atom, the tip is moved so it touches the atom.
Then the tip pulls or pushes the atom to a new place.
Moving atoms allows scientists to arrange them into tiny objects, so they can test their properties and try out new ideas.

This article is about orbital (electron) energy levels.
For compounds' energy levels, see chemical potential.
Simply defined as the different states of potential energy for electrons in an atom.
A quantum mechanical system can only be in certain states, so that only certain energy levels are possible.
The term energy level is most commonly used in reference to the electron configuration in atoms or molecules.
In other words, the energy spectrum can be quantized (see continuous spectrum for the more general case).
Energy levels are said to be degenerate, if the same energy level is obtained by more than one quantum mechanical state.
They are then called degenerate energy levels.
Intrinsic energy levels
Orbital state energy level
Assume an electron in a given atomic orbital.
The energy of its state is mainly determined by the electrostatic interaction of the (negative) electron with the (positive) nucleus.
The energy levels of an electron around a nucleus are given by :
where  is the Rydberg constant (typically between 1 eV and 103 eV), Z is the charge of the atom's nucleus,  is the principal quantum number, e is the charge of the electron,  is Planck's constant, and c is the speed of light.
The Rydberg levels depend only on the principal quantum number .
Fine structure splitting
Fine structure arises from relativistic kinetic energy corrections, spin-orbit coupling (an electrodynamic interaction between the electron's spin and motion and the nucleus's electric field) and the Darwin term (contact term interaction of s-shell electrons inside the nucleus).
Typical magnitude  eV.
Hyperfine structure
Spin-nuclear-spin coupling (see hyperfine structure).
Electrostatic interaction of an electron with other electrons
If there is more than one electron around the atom, electron-electron-interactions raise the energy level.
These interactions are often neglected if the spatial overlap of the electron wavefunctions is low.
Energy levels due to external fields
Zeeman effect
The interaction energy is:  with
Zeeman effect taking spin into account
Due to relativistic effects (Dirac equation), the magnetic moment arising from the electron spin is  with  the gyro-magnetic factor (about 2).
The interaction energy therefore gets .
Stark effect
Interaction with an external electric field (see Stark effect).
where  is an eigenvalue of the electronic molecular Hamiltonian (the value of the potential energy surface) at the equilibrium geometry of the molecule.
Crystalline materials
Crystalline materials are often characterized by a number of important energy levels.
The most important ones are the top of the valence band, the bottom of the conduction band, the Fermi energy, the vacuum level, and the energy levels of any defect states in the crystals.
The nucleus is the center of an atom.
It is made up of nucleons called (protons and neutrons) and is surrounded by the electron cloud.
The size (diameter) of the nucleus is between 1.6 fm (10−15 m) (for a proton in light hydrogen) to about 15 fm (for the heaviest atoms, such as uranium).
These sizes are much smaller than the size of the atom itself by a factor of about 23,000 (uranium) to about 145,000 (hydrogen).
Although it is only a very small part of the atom, the nucleus has most of the mass.
Almost all of the mass in an atom is made up from the protons and neutrons in the nucleus with a very small contribution from the orbiting electrons.
Neutrons have no charge and protons are positively charged.
Because the nucleus is only made up of protons and neutrons it is positively charged.
Things that have the same charge repel each other: this repulsion is part of what is called electromagnetic force.
Unless there was something else holding the nucleus together it could not exist because the protons would push away from each other.
The nucleus is actually held together by another force known as the strong nuclear force.
The word nucleus is from 1704, meaning “kernel of a nut”.
In 1844, Michael Faraday used nucleus to describe the “central point of an atom”.
The modern atomic meaning was proposed by Ernest Rutherford in 1912.
The use of the word nucleus in atomic theory, however, did not happen immediately.
In 1916, for example, Gilbert N. Lewis wrote in his famous article The Atom and the Molecule that "the atom is composed of the kernel and an outer atom or shell".
The nucleus of an atom is made up of protons and neutrons (two types of baryons) joined by the nuclear force.
These baryons are further made up of sub-atomic fundamental particles known as quarks joined by the strong interaction.
The nucleus is more or less a spheroid and may be somewhat prolate (long) or oblate (flat) or otherwise not entirely round.
If the nucleus can be considered to have a radius of the order of 5 fm (= 10 × 10-15 m), this means its cross-section is of the order of 10-28 m2, and its volume is about 10-42 m3.
Isotopes and nuclides
The isotope of an atom is based on the number of neutrons in the nucleus.
Different isotopes of the same element have very similar chemical properties.
Different isotopes in a sample of a chemical can be separated by using a centrifuge or by using a mass spectrometer.
The first method is used in producing enriched uranium from regular uranium, and the second is used in carbon dating.
The number of protons and neutrons together determine the nuclide (type of nucleus).
Protons and neutrons have nearly equal masses, and their combined number, the mass number, is about equal to the atomic mass of an atom.
The combined mass of the electrons is very small when compared to the mass of the nucleus; protons and neutrons weigh about 2000 times more than electrons.
The discovery of the electron by J. J. Thomson was the first sign that the atom had internal structure.
At the turn of the 20th century the accepted model of the atom was J. J. Thomson's "plum pudding" model in which the atom was a large positively charged ball with small negatively charged electrons embedded inside of it.
By the turn of the century physicists had also discovered three types of radiation coming from atoms, which they named alpha, beta, and gamma radiation.
Experiments in 1911 by Lise Meitner and Otto Hahn, and by James Chadwick in 1914 discovered that the beta decay spectrum was continuous rather than discrete.
That is, electrons were ejected from the atom with a range of energies, rather than the discrete amounts of energies that were observed in gamma and alpha decays.
This was a problem for nuclear physics at the time, because it indicated that energy was not conserved in these decays.
The problem would later lead to the discovery of the neutrino (see below).
In 1906 Ernest Rutherford published "Radiation of the α Particle from Radium in passing through Matter".
Geiger expanded on this work in a communication to the Royal Society with experiments he and Rutherford had done passing α particles through air, aluminum foil and gold foil.
More work was published in 1909 by Geiger and Marsden and further greatly expanded work was published in 1910 by Geiger, In 1911-2 Rutherford went before the Royal Society to explain the experiments and propound the new theory of the atomic nucleus as we now understand it.
Around the same time that this was happening (1909) Ernest Rutherford performed a remarkable experiment in which Hans Geiger and Ernest Marsden under his supervision fired alpha particles (helium nuclei) at a thin film of gold foil.
The plum pudding model predicted that the alpha particles should come out of the foil with their trajectories being at most slightly bent.
He was shocked to discover that a few particles were scattered through large angles, even completely backwards in some cases.
The discovery, beginning with Rutherford's analysis of the data in 1911, eventually led to the Rutherford model of the atom, in which the atom has a very small, very dense nucleus consisting of heavy positively charged particles with embedded electrons in order to balance out the charge.
As an example, in this model nitrogen-14 consisted of a nucleus with 14 protons and 7 electrons, and the nucleus was surrounded by 7 more orbiting electrons.
The Rutherford model worked quite well until studies of nuclear spin were carried out by Franco Rasetti at the California Institute of Technology in 1929.
By 1925 it was known that protons and electrons had a spin of 1/2, and in the Rutherford model of nitrogen-14 the 14 protons and six of the electrons should have paired up to cancel each other's spin, and the final electron should have left the nucleus with a spin of 1/2.
Rasetti discovered, however, that nitrogen-14 has a spin of one.
In 1930 Wolfgang Pauli was unable to attend a meeting in Tübingen, and instead sent a famous letter with the classic introduction "Dear Radioactive Ladies and Gentlemen".
In his letter Pauli suggested that perhaps there was a third particle in the nucleus which he named the "neutron".
He suggested that it was very light (lighter than an electron), had no charge, and that it did not readily interact with matter (which is why it had not yet been detected).
This desperate way out solved both the problem of energy conservation and the spin of nitrogen-14, the first because Pauli's "neutron" was carrying away the extra energy and the second because an extra "neutron" paired off with the electron in the nitrogen-14 nucleus giving it spin one.
Pauli's "neutron" was renamed the neutrino (Italian for little neutral one) by Enrico Fermi in 1931, and after about thirty years it was finally demonstrated that a neutrino really is emitted during beta decay.
In 1932 Chadwick realized that radiation that had been observed by Walther Bothe, Herbert L. Becker, Irène and Frédéric Joliot-Curie was actually due to a massive particle that he called the neutron.
In the same year Dmitri Ivanenko suggested that neutrons were in fact spin 1/2 particles and that the nucleus contained neutrons and that there were no electrons in it, and Francis Perrin suggested that neutrinos were not nuclear particles but were created during beta decay.
To cap the year off, Fermi submitted a theory of the neutrino to Nature (which the editors rejected for being "too remote from reality").
Fermi continued working on his theory and published a paper in 1934 which placed the neutrino on solid theoretical footing.
In the same year Hideki Yukawa proposed the first significant theory of the strong force to explain how the nucleus holds together.
With Fermi and Yukawa's papers the modern model of the atom was complete.
The center of the atom contains a tight ball of neutrons and protons, which is held together by the strong nuclear force.
Unstable nuclei may undergo alpha decay, in which they emit an energetic helium nucleus, or beta decay, in which they eject an electron (or positron).
After one of these decays the resultant nucleus may be left in an excited state, and in this case it decays to its ground state by emitting high energy photons (gamma decay).
The study of the strong and weak nuclear forces led physicists to collide nuclei and electrons at ever higher energies.
This research became the science of particle physics, the most important of which is the standard model of particle physics which unifies the strong, weak, and electromagnetic forces.
Modern nuclear physics
A nucleus can contain hundreds of nucleons  which means that with some approximation it can be treated as a classical system, rather than a quantum-mechanical one.
In the resulting liquid-drop model, the nucleus has an energy which arises partly from surface tension and partly from electrical repulsion of the protons.
The liquid-drop model is able to reproduce many features of nuclei, including the general trend of binding energy with respect to mass number, as well as the phenomenon of nuclear fission.
Superimposed on this classical picture, however, are quantum-mechanical effects, which can be described using the nuclear shell model, developed in large part by Maria Goeppert-Mayer.
Nuclei with certain numbers of neutrons and protons (the magic numbers 2, 8, 20, 50, 82, 126, ...) are particularly stable, because their shells are filled.
Much of current research in nuclear physics relates to the study of nuclei under extreme conditions such as high spin and excitation energy.
Nuclei may also have extreme shapes (similar to that of American footballs) or extreme neutron-to-proton ratios.
