Physicists study the nature of all matter and energy, including structures,
behaviour, formation/generation and the
interactions between the two. Physics can broadly be divided into
theoretical physics and experimental physics. Theoretical physics involves
developing models, or
theories, which attempt to explain and predict how and
why certain aspects of the world work and behave. Experimental physics
involves testing these theories, determining their limits and using the
results to amend or strengthen the theory as appropriate. All physicists
will generally work in both of these areas to some degree. Physicists
working at universities will also be required to spend time teaching
students.

Aussie physicist helps build ‘time machine’ to visit Big Bang
Vanessa Croll
The Daily Telegraph
May 5, 2020
Reprinted in "Perth
Now"
Dr Sarah Pearce
Pioneering and internationally recognised physicist and 2020 Telstra
NSW Business Woman of the Year Dr. Sarah Pearce is helping to build
a new generation radio telescope to discover galactic secrets.
The Square Kilometre Array (SKA) – a new generation in radio
telescope – will look back in time some 13 billion years to see the
beginning of the universe.
With one site in Australia and one in South Africa, CSIRO Astronomy
and Space Science deputy director Sarah Pearce hopes the SKA will
help answer some of life’s biggest questions.
“SKA in Australia will look back in time toward not long after the
Big Bang and hopefully, for the first time we will see when the very
first galaxy started to shine, this is called the Cosmic Dawn
Period,” Dr Pearce said.
“That helps you understand how galaxies are born, how they evolve
and how they eventually die. There isn’t a telescope that has been
able to take images of this yet.”
Dr Pearce – a pioneering and internationally recognised physicist
and 2020 Telstra NSW Business Woman of the Year – has been working
with international cohorts on this project for nine years.
“It’s important we understand where we came from and where we’re
going,” she said. “People are fascinated by the stars and the Big
Bang and our wider purpose in the universe.
“But this kind of research can have practical implications. The
Wi-Fi we use was created with some of the algorithms used first by
the CSIRO when they were trying to look at black holes.
“The SKA has enormous data rates and it will produce petabytes of
data. How we learn to deal with that will help us learn how to deal
with storing data in both science fields and industry.”

Square Kilometre Array (SKA) in Australia.
The radio telescope to be built in Australia is called SKA-low and
will be made up of 130,000 radio antenna that will look like 2m-high
metal Christmas trees spread over 65km of desert in Western
Australia. It will start conducting science observations mid-2020s
with a partial array.
“The reason we’re in the desert in WA is because what we are looking
for are extremely faint whispers,” Dr Pearce said.
“You can’t find them if you’re near a lot of people using phones,
microwaves, radios.”
Telstra Business Women’s Awards ambassador Alex Badenoch said while
Dr Pearce was the group’s 2020 NSW Business Woman, she was also
awarded the Public Sector and Academia Award.
“We commend [Dr] Pearce for her innovative space programs that have
significant global impact,” Ms Badenoch said. She is committed to
collaboration, and instead of being out to win, she is dedicated to
ensuring she and her team produce the best work possible.”

Duties and Tasks
Physicists are usually identified within three broad roles:
-
theoretical physicists, who develop
theories or models of how particular aspects of the world work
-
experimental physicists, who test these
theories, determining their limits and suggesting new approaches to them
-
applied physicists, who apply these
findings in practical settings, such as within industry and through the
introduction of new technology.
There is interaction between all three roles and physicists generally have
skills in each of these areas.
Physicists may perform the following tasks:
-
observe and measure phenomena in the physical
world, from the smallest subatomic particle through to the universe as a
whole
-
propose theories and models to explain phenomena
-
use computers to explore the consequences of
theories and models
-
build equipment to make new types of
measurements, which in many cases have never been attempted before
-
create new ways of understanding observations
that have been made
-
develop new materials, products and processes for
use in industry, medicine, defence and other areas of research and
development
Working Conditions
Physicists usually work in laboratories, offices or workshops, though some
may also carry out fieldwork in various environments, depending on the
nature of their research. Many physicists work in universities, where they
split their time between teaching and research work, however there are also
opportunities to work in government organisations or private industry. They
may work with radioactive substances and other restricted and/or potentially
harmful materials, which require strict safety and control procedures to be
followed to minimise danger. Physicists usually work standard business
hours, however overtime or weekend work may be required when setting up and
carrying out experiments or when conducting fieldwork.
Tools and technologies
Physicists use a variety of highly specialised instruments and laboratory
equipment to conduct, record and analyse experiments. Depending on the
nature of the experiment, this equipment may be used to heat or cool
materials to extreme temperatures, generate and measure electrical currents,
examine the atomic structure of matter, and carry out many other highly
technical and specialised tasks. They must also be familiar with computers
to control equipment, run simulations and to write reports based on their
findings.
Educational Requirements
To become a physicist you usually need to study a degree in science with
major in physics or nanotechnology. To improve your employment prospects,
you may need to complete further postgraduate study.

Professor
Alexander Prokhorov: Meet Australia's forgotten Nobel Prize winner
- CAMEO

11 July 1916 - 8
January 2002

laser is also a Nobel Prize winner. (Supplied: Alex Prokhorov)
Meet Alexander Prokhorov: the
Australian-born co-inventor of the laser and Nobel Prize winner you
have probably never heard of.
But that could be all about to change as top scientists and former
federal science minister Barry Jones push to have him more widely
recognised in Australia.
His discovery has helped transform almost everything we rely upon:
from surgery to the internet.
While he is a celebrated scientific hero in Russia, his formative
years were actually spent in far north Queensland.
In the year of what would have been his 100th birthday, Australian
scientists want us to know all about him, celebrate him and even
recognise him with a stamp in his honour.
Australia's 'little
Siberia'
Professor Prokhorov's family fled
to Australia as refugees from Tsarist Russia in 1912, eventually
settling in what was known as "little Siberia" — a Russian colony in
the Atherton Tablelands.
On July 11, 1916, Alexander Prokhorov was born in Butcher's Creek,
where he spent the first six years of his life.
At the tiny local school, the few records available show he had a
very rural upbringing and "was a talented little kid", according to
Australian National University physicist Hans-Albert Brochor.
His grandson, also named Alexander, told the ABC his grandfather
told him about the "very nice butterflies, jungles... and warm
climate".
"He got lost in the jungles once and all the village had to look
for him," grandson Alex said.
Fond memories of a 'magical' upbringing
Former Australian Science
Minister (1983-1990)
Dr. Barry Jones, who visited Professor Prokhorov on a trip to
Russia, said the scientist had a very fond memory of Australia.
"He had a very vivid and very affectionate view of Australia and
the openness and the colours and the trees and the magical
environment he lived in," Dr Jones said.
Professor Prokhorov's family returned to Russia in 1923 after the
Russian Revolution, where he finished his high school studies and
went on to study radio waves.
After serving with the Russian army in World War II and being
wounded twice he returned to study physics at the Soviet Union's
Institute of Atomic Energy where he developed the technologies that
made the laser possible.
He became a member of the Communist Party in 1950 and according to
Professor Bachor, Professor Prokhorov was actually trying to develop
a "death ray" while at the institute.
Death ray race led to laser revolution
In 1964, the Nobel Prize was jointly awarded to Professor Prokhorov,
his Russian colleague Nikolay Basov and also American Charles Townes
— who was independently working on the same research.
"Albert Einstein in Germany published papers that [proposed] a
way to amplify light in a machine... but for 40 years nobody could
build such a machine," Professor Bachor said.
"[Professor Prokhorov] was one of these people who had the right
idea and that was basically to put your amplifier between two
mirrors and bounce the light forwards and backwards many times so it
got stronger every time it went through the amplifier."
Professor Bachor said the research was part of a wider military
project during the Cold War.
"Both countries were trying everything ... lasers at the time
were thought of as death rays as you see them in Star Wars," he
said.
"The death rays were the initial program and then people came up
very rapidly with all sorts of ideas of what you could do — so you
could cut a hole and cutting a hole is very useful for cutting
metal, or welding a car or for surgery."
Lasers enabled the creation of a whole range of devices — from DVD
players, barcode scanners, 3D printers and even optical fibre cables
(the ones that provide superfast internet).
Professor Prokhorov died in 2002 from pneumonia.
In an interview with Professor Prokhorov obtained by Russian
historian Elena Govor, he pondered whether he would have won a Nobel
Prize if he had been born in a different place.
"This question cannot be answered unequivocally — however, being
born in Australia to some extent predetermined by the fact that I
won the Nobel Prize," he said according to a translation of the
interview.
"If I'd been born in a different place, my whole life would be
different.
"When I met with scientists from Australia at international
conferences, they are warmly welcomed me, and we have a mutual
sympathy and warm feelings of friendship."
Family viewed with suspicion by Australian authorities
The warmth did not extend to Australian authorities — intelligence
records show they were monitoring his father Michael's
[Mikhail] letters while they lived in
Australia.
One of the friends Michael Prokhorov wrote to, Alexander Zuzenko,
was a radical who published a Russian newspaper called Knowledge and
Unity in Brisbane, according to Dr Gorov.
Mr Zuzenko was later deported back to Russia.
Dr Gorov discovered some of the intelligence reports buried in the
National Library of Australia.
In one letter, authorities observe a Russian library has been
re-established in South Brisbane, "which may possibly form a
sort of club room where the malcontents can discuss their propaganda".
"It is noticeable that rarely is a Russian letter scrutinised in
which the revolutionary spirit is not aggressively displayed,"
censor's notes from another letter show.
"The conclusion to be arrived at is that if there are law
abiding Russians in Australia they don't write letters."
'Put him on a stamp': Jones
Dr Jones worked to have Professor Prokhorov's Australian-connection
acknowledged, ensuring a permanent reminder of his work at CSIRO's
labs in Atherton in 1987s.
"We decided to commemorate him by putting a commemorative plaque
which was inserted on a rock and I went up with CSIRO and various
other scientific luminaries and we unveiled... up there at Atherton
up in the glorious northern rainforest," he told the ABC.
"We could put him on a stamp maybe."
In 1996 the University of New South Wales made him an honorary
professor — and his grandson would like to see a scholarship or
conference named in his honour.
In the meantime, a group of physicists including Professor Bachor
are putting on a show to educate school children about Professor
Prokhorov's work and the history of lasers which they are putting on
for National Science Week (13-21 August).
"We have a very interactive show we basically tell the story but in
a way that the kids are familiar with we burst balloons, we show
them some tricks with lasers — we have a very entertaining show but
in the background they are going to learn a bit about the physics
what is a laser how does it work," Professor Bachor said.
Both of Prokhorov's parents died during World War II.
Prokhorov married geographer Galina Shelepina in 1941, and
they had a son, Kiril, born in 1945.
Following his father, Kiril Prokhorov became a physicist in
the field of optics and is currently leading a laser-related
laboratory at the A. M. Prokhorov General Physics Institute. |

Biographical Information as of 1964
Aleksandr Mikhailovich Prokhorov was born on July 11th, 1916, in
Australia. After the Great October Revolution he went in 1923 with
his parents to the Soviet Union.
In 1934 Alexander Prochorov entered the Physics Department of the
Leningrad State University. He attended lectures of Prof. V.A. Fock
(quantum mechanics, theory of relativity), Prof. S.E. Frish (general
physics, spectroscopy), and Prof. E.K.Gross (molecular physics).
After graduating in 1939 he became a postgraduate student of the
P.N. Lebedev Physical Institute in Moscow, in the laboratory of
oscillations headed by Academician N.D. Papaleksi. There he started
to study the problems of propagation of radio waves. In June 1941,
he was mobilized in the Red Army. He took part in the Second World
War and was wounded twice. After his second injury in 1944, he was
demobilized and went back to the laboratory of oscillations of the
P.N. Lebedev Physical Institute. There he began to investigate
nonlinear oscillations under the guidance of Prof. S.M. Rytov.
A 2016 Russian stamp in honour of
Alexander Prokhorov's birth in 1916 [in Australia!]
In 1946 he defended his thesis on the theme Theory of Stabilization
of Frequency of a Tube Oscillator in the Theory of a Small
Parameter.
Starting in 1947, upon the suggestion of Academician V.I. Veksler,
Prochorov carried out a study of the coherent radiation of electrons
in the synchotron in the region of centimetre waves. As a result of
these investigations he wrote and defended in 1951 his Ph.D. thesis
a “Coherent Radiation of Electrons in the Synchotron Accelerator”.
After the death of Academician I.D. Papaleksi in 1946, the
laboratory of oscillations was headed by Academician M.A.
Leontovich. Starting from 1950 being assistant chief of the
laboratory, Prochorov began to investigate on a wide scale the
question of radiospectroscopy and, somewhat later, of quantum
electronics. He organized a group of young scientists interested in
the subjects.
In 1954, when Academician M.A. Leontovich started to work in the
Institute of Atomic Energy, Prochorov became head of the laboratory
of oscillations, which position he still holds. In 1959 the
laboratory of radio astronomy headed by Prof. V.V. Vitkevitch) was
organized from one of the departments of the laboratory of
oscillations, and in 1962 another department was separated as the
laboratory of quantum radiophysics (headed by Prof. N.G. Basov).
Prokhorov with King Gustaf VI Adolf and
wife of American Charles Townes at the Nobel Prize banquet in 1964
Academician D.V. Skobeltzyn, director of the Institute, and
Academician M.A. Leontovich as well, rendered great assistance in
the development of the research on radiospectroscopy and quantum
electronics. The investigations carried out by Basov and Prochorov
in the field of microwave spectroscopy resulted in the idea of a
molecular oscillator. They developed theoretical grounds for
creation of a molecular oscillator and also constructed a molecular
oscillator operating on ammonia. In 1955, Basov and Prochorov
proposed a method for the production of a negative absorption which
was called the pumping method.
From 1950 to 1955, Prochorov and his collaborators carried out
research on molecular structures by the methods of microwave
spectroscopy.
In 1955 Professor Prochorov began to develop the research on
electronic paramagnetic resonance (EPR). A cycle of investigations
of EPR spectra and relaxation times in various crystals was carried
out, in particular investigations on ions of the iron group elements
in the lattice of Al2O3.
In 1955, Prochorov studied with A.A. Manenkov the EPR spectra of
ruby that made it possible to suggest it as a material for lasers in
1957. They designed and constructed masers using various materials
and studied characteristics of the masers as well. This research was
done in cooperation with the laboratory of radiospectroscopy of the
Institute of Nuclear Physics of the Moscow University; this
laboratory was organized by Prochorov in 1957. One of the masers
constructed for a wavelength of 21 cm is used in the investigations
of the radioastronomical station of the Physical Institute in
Pushino.
The EPR methods were also utilized for the study of free radicals.
In particular, the transition of a free radical of DPPH from a
paramagnetic state into an antiferromagnetic state at 0.3K was
observed.
In 1958 Prochorov suggested a laser for generation of far-infrared
waves. As a resonator it was proposed to use a new type of cavity
which was later called “the cavity of an open type”. Practically
speaking, it is Fabri-Pero’s interferometer. Similar cavities are
widely used in lasers.
At present Prochorov’s principal scientific interests lie in the
field of solid lasers and their utilization for physical purposes,
in particular for studies of multiquantum processes. In 1963, he
suggested together with A.S. Selivanenko, a laser using two-quantum
transitions.
Alexander Prochorov is Professor at the Moscow State University and
Vice-President of URSI.
He married in I941; his wife, G.A. Shelepina, is a geographer. They
have one son.
Laser Physics Workshop -
Special Tribute
In 1959, Prokhorov became a professor of physics at Moscow State
University – the most prestigious university in the Soviet Union.
The same year, he was awarded the Lenin Prize. In 1960, he became a
corresponding member of the Russian Academy of Sciences and, in
1966, he was elected to a full membership rank at Academy.
In 1967, he was awarded his first Order of Lenin. He received five
of those highest awards during his life in 1967, 1969, 1975, 1981
and 1986. In 1968, he became vice-director of the Lebedev Institute
and in 1971 took a position of Head of Laboratory of another
prestigious Soviet institution of higher education, the Moscow
Institute of Physics and Technology.
In the same year, he was elected a member of the American Academy of
Arts and Sciences. Between 1982 and 1998, Prof. Prokhorov served as
acting director of the General Physics Institute at the Russian
Academy of Sciences, and after 1998 as its honorary director.
In 1992 Professor Alexander M Prokhorov, was a principal founder of
the annual International Laser Physics Workshop (LPHYS'). During the
following ten years he served as the conference permanent Chairman
until his death in 2002.
