Giuseppe Mercalli - seismologist

Giuseppe Mercalli became southern Europe's biggest
authority on earthquakes and volcanic activity

Scientist who invented Mercalli Scale died in fire

The seismologist and volcanologist Giuseppe Mercalli, who at the time of his death was director of the Vesuvius Observatory, died in a fire at his home in Naples on this day in 1914.

The initial suspicion was that Mercalli, who devised a scale for determining the strength of earthquakes according to the intensity of shaking, had knocked over a paraffin lamp accidentally after falling asleep while working late.

However, an examination of his remains suggested by may have been strangled after disturbing an intruder, who then soaked his clothes in petrol before setting light to them. A sum of money worth the equivalent of $1,400 (€1,250) today was missing, although no one was ever apprehended for the crime.

Born in Milan, Mercalli was ordained a Roman Catholic priest and became a professor of Natural Sciences at the seminary of Milan, although he left under something of a cloud because of his support for Antonio Rosmini, a controversial priest and philosopher who campaigned for social justice and was fiercely critical of various aspects of how the Roman Catholic church operated.

After he had left, the Italian government appointed him a professor at Domodossola in Piedmont, followed by a post at Reggio di Calabria. He was professor of geology at the University of Catania in the late 1880s and was given a post at the Naples University in 1892. He became director of the Vesuvius Observatory in 1911.

He is best remembered for the Mercalli intensity scale for measuring earthquakes which, in modified form, is still used today.

While studying seismic activity in Italy in the late 19th century, Mercalli’s access to seismic instrumentation was limited. Most of Mercalli's information came from personal accounts and observations of damage. To provide consistency in his analyses, he decided he needed a way to measure the relative effects of each event.

He first developed a scale with six degrees, with the most disastrous earthquakes given an intensity of six, but felt that this did not provide enough precision.  Another intensity scale called the deRossi-Forel scale that was gaining in prominence at the same time had the advantage of 10 degrees of intensity, although Mercalli felt it lacked meaningful description.

Mercalli was ordained as a priest before
beginning his scientific career

In 1902, Mercalli modified this 10-degree scale to include the detail he desired, and his new scale quickly caught on among European scientists

Mercalli also observed eruptions of the volcanoes Stromboli and Vulcano in the Aeolian Islands and his descriptions of these eruptions became the basis for two indices in the Volcanic Explosivity Index: 1 - Strombolian eruption, and 2 - Vulcanian eruption.

The scale has been tweaked by various other seismologists but remains the basis for determining an earthquake’s intensity. It is now known as the Modified Mercalli Intensity Scale.

Mercalli also engaged in detailed cataloguing of Italian earthquakes, which enabled him to produce a book - I vulcani e fénomeni vulcanici in Italia - which he used to assemble a clear picture of where most of the events happened.

Mercalli's work built his reputation across southern Europe, and he was often called upon to study events throughout the continent.  He travelled to Spain in 1884 to examine the aftermath of the Andalusian earthquake, and in 1887 Mercalli was the lead investigator of the deadly event in Imperia along the French and Italian Riviera.

He became famous even beyond scientific circles, to the extent that his death and the speculation over the circumstances was reported in the New York Times.

Some fascinating buildings line Piazza Mercato in the
medieval heart of Domodossola

Travel tip:

The name Domodossola is familiar to many Italian children as a line - ‘D’ is for Domodossola - recited in learning the alphabet at school. It is, in fact, a very pleasant town in northern Piedmont, close to the border with Switzerland and the last town at the Italian end of the Simplon Pass and the Simplon railway tunnel. Domodossola has a charming medieval centre around the Piazza Mercato, which has a number of interesting buildings. The Collegiale Church of Santi Gervasio and Protasio is the town’s most important church, while just outside the town is the Sacro Monte Calvario, a Roman Catholic sanctuary that is a UNESCO World Heritage site. The Palazzo Silva in Piazza Chiossi houses a civic museum. The area is surrounded by outstanding Alpine countryside, which can be admired from a light railway linking Domodossola and Locarno in Switzerland.

The vast crater of Mount Vesuvius, which remains classified
as an active volcano despite being quiet since 1944

Travel tip:

The Vesuvius Observatory today is part of the Mount Vesuvius National Park, which was created in 1955. The crater of the volcano itself is accessible to visitors, albeit by guided tour only, and there is a road to within 200 metres of it, but after that the ascent is on foot only.  The crater is about 200 metres deep and has a maximum diameter of about 600 metres. The climb is said to be well worth it because the view takes in the entire coastline from the Gulf of Gaeta, some 84km (52 miles) to the north, to the Sorrento peninsula. Visitors can take the Naples-Sorrento line of the Circumvesuviana railway and get off at Ercolano station, from where a shuttle bus runs to the park. As well as the observatory, there is a museum, a visitor centre, a restaurant and a shop where you can buy Lacrima Christi del Vesuvio, the wine made from the grapes grown on the sloped of the volcano.

Renato Dulbecco - Nobel Prize-winning physiologist

Research led to major breakthrough in knowledge of cancer

Renato Dulbecco emigrated to the United States
1946 after studying at the University of Turin

Renato Dulbecco, a physiologist who shared the 1975 Nobel Prize in Physiology or Medicine for his role in drawing a link between genetic mutations and cancer, was born on this day in 1914 in Catanzaro in Calabria.

Through a series of experiments that began in the late 1950s after he had emigrated to the United States, Dulbecco and two colleagues showed that certain viruses could insert their own genes into infected cells and trigger uncontrolled cell growth, a hallmark of cancer.

Their findings transformed the course of cancer research, laying the groundwork for the linking of several viruses to human cancers, including the human papilloma virus, which is responsible for most cervical cancers.

The discovery also provided the first tangible evidence that cancer was caused by genetic mutations, a breakthrough that changed the way scientists thought about cancer and the effects of carcinogens such as tobacco smoke.

Dulbecco, who shared the Nobel Prize with California Institute of Technology (Caltech) colleagues Howard Temin and David Baltimore, then examined how viruses use DNA to store their genetic information and, in his studies of breast cancer, pioneered a technique for identifying cancer cells by the proteins present on their surface.

Dulbecco found that viruses such as the human
papilloma virus could cause cell mutations

His proposal in 1986 to catalogue all human genes can be seen as the beginnings of the Human Genome Project, which was completed in 2003.

The son of a civil engineer, Dulbecco grew up in Liguria after his family moved from Catanzaro to the coastal city of Imperia. He graduated from high school at 16 and went on to the University of Turin, receiving his medical degree in 1936. He became friends there with two other future Nobel prizewinners, Rita Levi-Montalcini and Salvador Luria, who were fellow students.

Immediately upon graduating, he was required to do two years’ military service. He was discharged in 1938 but soon afterwards called up again as Italy entered the Second World War, joining the Italian Army as a medical officer.

His role eventually took him to the Russian front, where he suffered an injury to his shoulder that meant he was sent back to Italy to recuperate. Disillusioned with Mussolini and horrified at learning of the fate of Jews under Hitler, he decided not to return to the Army, joining the resistance instead. He stationed himself in a remote village outside Turin, tending to injured partisans.

After the war, he was briefly involved with politics, firstly on the Committee for National Liberation in Turin and then on the city council, but soon returned to Turin University to study physics and conduct biological research.

Dulbecco's fellow Turin University graduate
Salvador Duria also moved to America

With the encouragement of Levi-Montalcini, who would win a Nobel Prize in 1986 for her work in neurobiology, in 1946, he moved to United States, rejoining Luria, who shared a Nobel in 1969 for discoveries about the genetics of bacteria, at Indiana University, where they studied viruses. In the summer of 1949 he moved to Caltech, where he began his work on animal oncoviruses.

Dulbecco worked with Dr. Marguerite Vogt on a method of determining the amount of polio virus present in cell culture, a step that was vital in the development of polio vaccine, before becoming intrigued by a thesis written by Howard Temin on the connection between viruses and cancer.

He left Caltech in 1962 to move to the Salk Institute, a polio research facility in San Diego, and then in 1972 to the Imperial Cancer Research Fund (now Cancer Research UK) in London.

There was a mixed reaction in Italy when it was learned that ‘their’ Nobel Prize winner had become an American citizen. In fact, his Italian citizenship was revoked, although when he moved back to Italy in 1993 to spend four years as president of the Institute of Biomedical Technologies at National Council of Research in Milan he was made an honorary citizen.

Married twice, with three children, Dulbecco died in La Jolla, California, in 2012, three days before what would have been his 98th birthday.

From its elevated position, Catanzaro has views towards
the Ionian Sea and the resort of Catanzaro Lido

Travel tip:

Occupying a position 300m (980ft) above the Gulf of Squillace, Catanzaro is known as the City of the Two Seas because, from some vantage points, it is possible to see the Tyrrhenian Sea to the north of the long peninsula occupied by Calabria as well as the Ionian Sea to the south.  The historic centre, which sits at the highest point of the city, includes a 16th century cathedral built on the site of a 12th century Norman cathedral which, despite being virtually destroyed by bombing in 1943, has been impressively restored.  The city is about 15km (9 miles) from Catanzaro Lido, which has a long white beach typical of the Gulf of Squillace.

Travel tip:

The beautiful city of Imperia, on Liguria's Riviera Poniente about 120km (75 miles) west of Genoa and 60km (37 miles) from the border with France, came into being in 1923 when the neighbouring ports of Porto Maurizio and Oneglia, either side of the Impero river, were merged along with several surrounding villages to form one conurbation.  Oneglia, once the property of the Doria family in the 13th century, has become well known for cultivating flowers and olives. Porto Maurizio, originally a Roman settlement called Portus Maurici, has a classical cathedral dedicated to San Maurizio, which was built by Gaetano Cantoni and completed in the early 19th century.

Giovanni Alfonso Borelli – physiologist and physicist

Neapolitan was the first to explain movement

Giovanni Alfonso Borelli was a
pioneer of biomechanics

The scientist who was the first to explain muscular movement according to the laws of statics and dynamics, Giovanni Alfonso Borelli, was born on this day in 1608 in Naples.

Borelli was also the first to suggest that comets travel in a parabolic path.

He was appointed professor of mathematics at Messina in 1649 and at Pisa in 1656. After 1675 he lived in Rome under the protection of Christina, the former Queen of Sweden. She had abdicated her throne in 1654, had converted to Catholicism and gone to live in Rome as the guest of the Pope.

Remembered as one of the most learned women of the 17th century, Christina became the protector of many artists, musicians and intellectuals who would visit her in the Palazzo Farnese, where she was allowed to live by the Pope.

Borelli’s best known work is De Motu Animalium - On the Movement of Animals - in which he sought to explain the movements of the animal body on mechanical principles. He is therefore the founder of the iatrophysical school. He dedicated this work to Queen Christina, who had funded it, but he died of pneumonia in 1679 before it was published.

A page from Borelli's De Motu
Animalium on arm movement

For this work he has become known as the father of modern biomechanics. The American Society of Biomechanics named its most prestigious award the Giovanni Borelli Award in 1984.

The award is given to scientists for the originality, quality and depth of their research, and its relevance to the field of biomechanics.

Borelli also wrote astronomical works, including a treatise in 1666 that considered the influence of attraction on the satellites of Jupiter.  In a letter published in 1665, using the pseudonym Pier Maria Mutoli, he was the first to suggest the idea that comets travel in a parabolic path.

The Castel Nuovo in Naples, built in the 13th century
and rebuilt by Alfonso I in 1453

Travel tip:

Borelli was born in the Castel Nuovo area of Naples to a Spanish infantryman serving in the city and a young Neapolitan girl. The castle was called ‘nuovo’, new, when it was built in the 13th century to distinguish it from two earlier ones in Naples, Castel d’Ovo and Castel Capuano. Alfonso I, King of Naples and Sicily, had it completely rebuilt in 1453, the year of his triumphant entry into Naples. Alfonso later ordered the construction of the superb Arco di Trionfo, one of the most significant expressions of early Renaissance culture in southern Italy.

The Palazzo Farnese in Rome, once home of the former
Queen Christina of Sweden, now houses the French embassy

Travel tip:

Palazzo Farnese, where Borelli would visit his patron, Queen Christina, is one of the most important High Renaissance palaces in Rome. Owned by the Italian republic, the palazzo in Piazza Farnese was given to the French Government in 1936 for a period of 99 years and currently serves as the French embassy in Italy. One of the scenes in Puccini’s opera Tosca is set in Palazzo Farnese.

Rafael Bombelli – mathematician

First person to explain algebra in simple language

The front cover of the 1579 edition of
Bombelli's text, published in Bologna

Rafael Bombelli, the mathematician regarded as the inventor of complex numbers, was baptised and was also probably born on this day in 1526 near Bologna.

He wrote a book about algebra in simple language that could be understood by everyone, giving a comprehensive account of what was known about the subject at the time. The first three volumes, published in 1572, were the first European texts to explain how to perform computations with negative numbers.

Rafael Bombelli was the eldest son of Antonio Mazzoli, a wool merchant, who had changed his name to Bombelli to disassociate himself from the reputation of his family. His grandfather had taken part in a failed attempt to seize Bologna on behalf of the Bentivoglio family but had been caught and executed. Antonio Mazzoli was able to return to Bologna only after changing his name to Bombelli.

It is thought that Rafael Bombelli did not attend university but was taught by an engineer-architect named Pier Francesco Clementi.

He followed Clementi into the profession and acquired a patron, Alessandro Rufini. His patron was given the right to reclaim marsh land in the Val di Chiana by the Pope and Bombelli worked on this project until 1555 when there was an interruption to the reclamation work.

Bombelli wrote his algebra book while staying in
his patron's villa in Frascati, outside Rome

While he was waiting for the project to start again he decided to write an algebra book, while living in the comfortable surroundings of his patron’s villa just outside Rome in Frascati.

He felt that the reason for arguments between mathematicians was the lack of a careful exposition of the subject. The only books about algebra were not accessible to people without a thorough grasp of mathematics and he deliberately used simple language to make the book available to people who had not received higher education.

He died in Rome in 1572, soon after the first three volumes of the book were published. The unfinished manuscript of the other two volumes was discovered in a library in Bologna in 1923 and published in 1929.

Despite the delay in publication, Bombelli’s Algebra was a very influential work and was praised by later mathematicians because his analysis of the subject showed him to be far ahead of his time.

A crater on the moon has been named the Bombelli crater in honour of him.

The church of Santa Maria Assunta in Borgo Panigale

Travel tip:

Bombelli’s family lived in Borgo Panigale, a small town to the north of Bologna, which was annexed to the city by the Fascist government in 1937. It is now home to Bologna’s Guglielmo Marconi airport and the motorbike manufacturer Ducati. The Bologna artist Elisabetta Sirani painted an altarpiece for the parish church of Borgo Panigale. It is thought the name stems in part from the land around the site of the town, which was formerly used for the cultivation of the foxtail millet cereal called panìco in Italian.

The facade of the Villa Falconieri in
Frascati, where Bombelli stayed

Travel tip:

The Villa Falconieri in Frascati, to the south of Rome, was originally called Villa Rufina, having been built for Alessandro Rufini in 1546. It was while staying in this villa that Bombelli wrote his famous work on Algebra, which he dedicated to his patron, Rufini. The villa, which was renovated by the leading Roman Baroque architect Francesco Borromini after it was sold in 1628, houses many beautiful frescoes and is surrounded by splendid Italian gardens with a small lake bordered by cypresses. Now the headquarters of the Vivarium Novum Latin and Humanities Academy, it is open to the public from 10am to 1pm each Sunday.

Caterina Scarpellini – astronomer and meteorologist

Female ‘assistant’ remembered for her important discoveries

Caterina Scarpellini moved to work at
Campidoglio Observatory aged 18

The astronomer Caterina Scarpellini, who discovered a comet in 1854 and was later awarded a medal by the Italian government for her contribution to the understanding of astronomy and other areas of science, died on this day in 1873 in Rome.

Caterina had moved from her native Foligno in Umbria to Rome at the age of 18 to work as an assistant to her uncle, Abbe Feliciano Scarpellini, who was the director of the Roman Campidoglio Observatory. He had been appointed in 1816 by Pope Pius VI to a new chair of sacred physics in the Roman College of the Campidoglio, marking a turning point in the attitude of the Roman Catholic Church to science.

From 1847 onwards, Caterina edited Corrispondenza Scientifica in Rome, a bulletin publishing scientific discoveries. She carried out her observations six times a day and reported on her findings.

The observatory was part of the Palazzo Senatorio on
Piazza del Campidoglio in the centre of Rome

She married Erasmo Fabri, who was also an assistant at the observatory, and together they established a meteorological station in Rome in 1856.

Caterina published reports of her astronomical observations and meteorological measurements in Italian, French and Belgian journals and also wrote about electrical, magnetic and geological phenomena.

Along with another scientist, she reported on a chemical analysis of sand that had fallen in Rome over three nights in February 1864, which she discovered had blown there from the Sahara desert during a storm.

She compiled the first Italian meteor catalogue and was the only observer in Rome of the 1866 Leonid meteor shower.

Caterina Scarpellini, here depicted in a magazine
illustration, made many important scientific findings

Caterina also wrote about Saturn’s rings, her ideas about the formation of the planets and her hypotheses concerning celestial mechanics.

She became a member of the Accademia dei Georgofili in Florence, an historic institution promoting scientific and agricultural research.

Her writings on the influence of the moon on earthquakes brought her honours from the Moscow Imperial Society of Naturalists and the Viennese Royal Geological Institute.

After Caterina’s death at the age of 65 following a stroke, a statue of her was erected in the Campo Verano cemetery in Rome. A crater on the planet Venus has been named after her.

The Palazzo Orfini in Foligno, where a printing shop
opened in 1470, printing Dante's Divine Comedy

Travel tip:

Foligno, where Caterina Scarpellini was born in 1808, is an ancient town in the province of Perugia in Umbria, situated 40km (25 miles) south east of Perugia. It has suffered several major earthquakes, including one as recently as 1997, but still standing are the 13th century Palazzo Communale and the Renaissance-style Palazzo Orfini, where a printing shop opened in 1470 and Dante’s Divine Comedy was printed there in 1472, becoming the first book to be printed in the Italian language.

The present-day Rome Observatory is in Villa di
Parco Mellini, at the top of Monte Mario

Travel tip:

The Campidoglio Observatory in Rome, where Caterina worked as assistant to her uncle, was located in the eastern tower of the Palazzo Senatorio in Piazza del Campidoglio on the top of Capitoline Hill. The observatory was later acquired by the Italian state and its equipment was transferred to the Villa di Parco Mellini at the top of Monte Mario outside Rome, which is still the location of the Astronomical Observatory of Rome and an Astronomical Museum housing an important collection of historic astronomical instruments.

Enrico Bombieri – Mathematician

Brilliant professor who won top award in his field at just 34

Enrico Bombieri is one of the
world's leading mathematicians

The mathematician Enrico Bombieri, one of the world’s leading authorities on number theory and analysis, which has practical application in the world of encryption and data transmission, was born on this day in 1940 in Milan.

Bombieri, who is also an accomplished painter, won the Fields Medal, an international award for outstanding discoveries in mathematics regarded in the field of mathematical sciences as equivalent to a Nobel Prize, when he was a 34-year-old professor at the University of Pisa in 1974.

As well as analytic number theory, he has become renowned for his expertise in other areas of highly advanced mathematics including algebraic geometry, univalent functions, theory of several complex variables, partial differential equations of minimal surfaces, and the theory of finite groups.

Mathematics textbooks now refer to several discoveries named after him in his own right or with fellow researchers, including the Bombieri-Lang conjecture, the Bombieri norm and the Bombieri–Vinogradov theorem.

Enrico Bombieri read his first book of algebra when he was
eight and wrote his first scholarly article when he was 17

He has been described as a "problem-oriented" scholar - one who tries to solve deep problems rather than to build theories.

According to colleagues, his analytical ability, combined with great powers of innovation, enable him to recognize elements of a solution that may already be present and to apply techniques and results from other fields to reach a final conclusion.

The fourth child and only son of a banker in Milan, Bombieri is said to have read his first algebra book at the age of eight.

He became more seriously interested in maths began at high school when, as a 15-year-old student, he picked up a book on number theory that introduced him to the great 19th century German mathematician Bernhard Riemann. He developed a fascination with numbers that never left him.

He published his first scholarly article in 1957, while still only 16 years old. In 1963, aged 22, he graduated in mathematics at the University of Milan and then studied at Trinity College, Cambridge.

Enrico Bombieri emigrated to the
United States in 1977

Between 1963 and 1966, Bombieri was an assistant professor and then a full professor at the University of Cagliari, holding the same position at the University of Pisa until 1974 and then at the Scuola Normale Superiore in Pisa from 1974 to 1977.

From Pisa he emigrated in 1977 to the United States, where he became a professor at the School of Mathematics at the Institute for Advanced Study in Princeton, New Jersey. In 2011 he became professor emeritus.

Bombieri has always been keen to disprove the notion that mathematicians are by nature single-focused nerds with no interests beyond their own field.

As a young man, he was a student of Alpine botany, in particular wild orchids, and has become an accomplished painter.

He experimented with pencil drawings and water colours at a young age and throughout his academic life has always carried paints and brushes with him on his travels.

He began to take his art more seriously after moving to the United States, enrolling to study study painting and printmaking at Mercer County Community College at West Windsor, New Jersey.

Bombieri paints people, animals and landscapes. His paintings are described as often surreal or intentionally ambiguous, although he also accepts commissions for portraits.

One work he is said to have been particularly proud of depicts a giant chessboard by a lake, with pieces placed to represent a critical point in the historic match between world champion Garry Kasparov and the chess-playing computer, Deep Blue.

Bombieri himself was a member of the Cambridge University chess team during his time at Trinity College.

The cloister at the main building of the University of Milan,
founded in 1924 after the merger of other institutions 

Travel tip:

The University of Milan was founded in 1924 from the merger of the Accademia Scientifico-Letteraria (Scientific-Literary Academy)and the Istituti Clinici di Perfezionamento (Clinical Specialisation Institutes), established in 1906. By 1928, the University already had the fourth-highest number of enrolled students in Italy, after Naples, Rome and Padua. Its premises are located primarily in Città Studi, the university district which was developed from 1915 onwards to the northeast of the city centre, although there are other buildings around the city that are now part of the University.  The streets of the Città Studi area are notable for bars, pizza restaurants and ice cream shops.

There is much more to historic Pisa than the
Campo dei Miracoli and the Leaning Tower

Travel tip:

Many visitors to Pisa confine themselves to the Campo dei Miracoli, where the attractions are the famous Leaning Tower, the handsome Romanesque cathedral and its impressive baptistry. But there is much more to Pisa. The University of Pisa, founded in 1343, now has elite status, rivalling Rome’s Sapienza University as the best in Italy, and a student population of around 50,000 makes for a vibrant cafe and bar scene. There is also much to see in the way of Romanesque buildings, Gothic churches and Renaissance piazzas.

Fabiola Gianotti - particle physicist

First woman to be director-general of CERN

Fabiola Gianotti - the would-be concert pianist
who instead became a brilliant physicist

The particle physicist Fabiola Gianotti, who in 2016 became the first woman to be made director-general in the 64-year history of the European Organisation for Nuclear Research, was born on this day in 1960 in Rome.

She led one of the two teams of physicists working for the organisation - general known as CERN after its title in French - whose experiments in 2012 resulted in the discovery of the Higgs boson, the particle that explains why some other elementary particles have mass.

The discovery was regarded as so significant in the advancement of scientific knowledge that it was nicknamed the “God particle.”

As the project leader and spokesperson of the ATLAS project at CERN, which involved a collaboration of around 3,000 physicists from 38 countries, Dr. Gianotti announced the discovery of the particle.

Their work involved the Large Hadron Collider (LHC), the world's largest and most powerful particle collider and the largest machine of any kind on the planet, which lies in a tunnel 27km (17 miles) in circumference, 175 metres (574 ft) beneath the France–Switzerland border near Geneva.

underground on the France-Switzerland border

Her team were awarded science’s most lucrative award, a special Fundamental Physics Prize worth $3 million. Time magazine named her among its people of the year; Forbes placed her in its top 100 influential women list.

Brought up in Milan the daughter of a geologist from Piedmont who taught her to love nature, and a mother from Sicily who was passionate about music and art, Dr. Gianotti had ambitions to become a prima ballerina as a child, when she dreamt of becoming a dancer with the Bolshoi at Teatro alla Scala in Milan.

She also considered becoming a classical pianist, such was her talent for music. She spent two years at the Milan Conservatory, but after earning a PhD in physics at the University of Milan, she began her career at CERN with a graduate fellowship in 1994.

Fabiola Gianotti was inspired to break the traditional male
domination of particle science by a biography of Marie Curie

Dr. Gianotti was inspired to devote herself to scientific research after reading a biography of Marie Curie, who developed the theory of radioactivity, techniques for isolating radioactive isotopes, and discovered the elements polonium and radium as well as being the mother of two children.

Even though particle physics has traditionally been a male-dominated domain - even now only 12 percent of the 2,500 physicists and engineers at CERN are women and only 20 per cent of the team that worked on the ATLAS project were women - Dr. Gianotti claims that she has never had a sense that she was discriminated against for being female.

However, she has argued that women in particle physics should be given more support when having children, claiming that a lack of support made it difficult for her to marry and start a family, a decision for which she has expressed regret.

Gianotti on the cover of Time magazine

The author or co-author of more than 500 publications in peer-reviewed scientific journals, Dr. Gianotti is is a promoter of the “Open Science” movement, in particular the publication of scientific works in open access journals and the development of open access hardware and software in order to spread scientific knowledge to less-privileged countries.

Brought up a Catholic, Gianotti insists that religion and science are not in competition with each other, saying that while science cannot demonstrate or disprove the existence of God, religion has to respect science, and they should co-exist in a climate of tolerance.

She lives in in Switzerland in an apartment with a view of Lake Geneva and Mont Blanc, plays music by her favourite composers on a Yamaha upright piano, has a passion for cooking and Italian culture.

The Milan Conservatory, Italy's largest music college, has
a star-studded list of alumni

Travel tip:

The Milan Conservatory - also known as Conservatorio di musica “Giuseppe Verdi” di Milano - was established by a royal decree of 1807 in Milan, capital of the Napoleonic Kingdom of Italy. It opened the following year with premises in the cloisters of the Baroque church of Santa Maria della Passione in Via Conservatorio. The largest institute of musical education in Italy, its alumni include Giacomo Puccini, Amilcare Ponchielli, Arrigo Boito, Pietro Mascagni, Riccardo Muti and Ludovico Einaudi.

Da Vinci's The Last Supper is one of the many
reasons to visit Milan

Travel tip:

Galileo demonstrates potential of telescope

Scientist unveiled new instrument to Doge of Venice

How the Milanese artist Giuseppe Bertini imagined the
scene as Galileo demonstrated his telescope to the Doge

The scientist and inventor Galileo Galilei demonstrated the wonders of the telescope to an audience of Venetian lawmakers on this day in 1609.

The 90th Doge, Leonardo Donato, and other members of the Venetian senate accompanied Galileo to the top of the campanile of St Mark’s Basilica, where each took it in turn to look through the instrument.

The meeting had been arranged by Galileo’s friend, Paolo Sarpi, who was a scientist, lawyer and statesman employed by the Venetian government. The two were both professors at the University of Padua.

Galileo, whose knowledge of the universe led him to be called the ‘father of observational astronomy’, was for many years wrongly credited with the invention of the telescope when in fact the first to apply for a patent for the device was a Dutch eyeglass maker named Hans Lippershey.

However, Galileo’s work using uncertain details of Lippershey’s design certainly took the idea to a different level.

Like Galileo, Paolo Sarpi was a professor
at the University of Padua

Whereas Lippershey’s device magnified objects by about three times, Galileo eventually produced a telescope with a magnification factor of 30.

The one he demonstrated on August 25, 1609, is thought to have had a factor of about eight or nine.

Galileo was the first to realise the potential of the telescope for astronomical study.

He was able to make out mountains and craters on the moon, as well as a ribbon of diffuse light arching across the sky — the Milky Way.  Galileo also discovered the rings of Saturn, sunspots and four of Jupiter's moons.

It was his findings on Jupiter’s moons in January 1610 that would lead him indirectly into trouble with the Roman Inquisition over his belief in heliocentrism, the concept that the sun and not the Earth was the centre of the solar system, as had been theorised by the Polish scientist Nicolaus Copernicus in the previous century.

In observing the three objects in proximity to the planet Jupiter that he had originally thought to be distant stars, he noticed that their position relative to the planet changed in a way that would have been inexplicable if they had really been fixed stars.

One day he noticed that one of them had disappeared altogether only to reappear later and within a few days had concluded that they were orbiting Jupiter. When, later in the year, he discovered that the planet Venus had ‘phases’ similar to the earth’s Moon, when differences in appearance suggested different positions in the sky, he began to subscribe firmly to the Copernican theory.

This flew in the face of a major part of Roman Catholic belief, based on the Aristotelian principle that all heavenly bodies orbited the Earth.

In time, Galileo was found guilty of heresy and forced to recant his views under threat of torture. He would have spend the last years of his life in prison had the court not shown some clemency and commuted his sentence to house arrest.

The campanile of St Mark's is a famous landmark
in Venice, towering over the basilica

Travel tip:

The Campanile of St Mark’s has become one of the symbols of Venice, instantly recognisable as part of the landscape of St Mark’s Square - Piazza San Marco - standing away from the basilica itself. Constructed in the ninth century, one of its first uses was a watchtower or lighthouse. Over the centuries it has been restored and added to several times, often following regular lightning strikes.  It assumed its definitive shape in the 16th century with restorations made to repair damage caused by the earthquake of March 1511, when the belfry, attic and spire were added. The whole structure collapsed in 1902, a few days after a large crack appeared in the north wall, it is thought because of erosion of the foundations after almost 1,000 years, but was rebuilt over the following 10 years.

Travel tip:

Galileo lived under house arrest was Villa Gioella, a house he rented a couple of miles from the from the centre of Florence in the Arcetri hills.  In Galileo’s time it was a farmhouse, surrounded by many acres of land. The area is also home to the Arcetri Observatory, which was opened in 1872 after astronomers at La Specola Observatory, not far from the Pitti Palace, decided that pollution from artificial light was making clear images impossible.

Umberto Guidoni - astronaut

First European to step on to the International Space Station

Guidoni flew two Space Shuttle missions
during his time at NASA in Texas

The astronaut Umberto Guidoni, who spent almost 28 days in space on two NASA space shuttle missions, was born on this day in 1954 in Rome.

In April 2001, on the second of those missions, he became the first European astronaut to go on board the International Space Station (SSI).

After retiring as an active astronaut in 2004, Guidoni began a career in politics and was elected to the European Parliament as a member for Central Italy.

Although born in Rome, Guidoni’s family roots are in Acuto, a small hilltown about 80km (50 miles) southeast of the capital, in the area near Frosinone in Lazio known as Ciociaria.

Interested in science and space from a young age, Guidoni attended the Gaio Lucilio lyceum in the San Lorenzo district before graduating with honours in physics specializing in astrophysics at the Sapienza University of Rome in 1978, obtaining a scholarship from the National Committee for Nuclear Energy, based outside Rome in Frascati.

He worked in the Italian Space Agency as well as in the European Space Agency. One of his research projects was the Tethered Satellite System, which was part of the payload of the STS-46 space shuttle mission.

Guidoni moved to Houston, Texas and trained for a year as an alternate payload specialist for that mission, for which he was part of the group of scientists coordinating the scientific operations of the Space Shuttle Atlantis from the ground.

Republic during his 2001 mission

He made his first spaceflight aboard the Space Shuttle Columbia in 1996, which included the second flight of the TSS system (TSS-1R). Columbia launched on February 22, returning to the Kennedy Space Center on March 9, having completed 252 orbits, covering 10 million kilometers in 377 hours and 40 minutes .

His work in space focused on the control of the TSS’s electrodynamic experiments, which demonstrated, for the first time, the possibility of generating electrical power from space.

Guidoni’s second experience in space came on board the Space Shuttle Endeavour, on a Space Station assembly flight in 2001, a mission that included the inaugural flight of the Raffaello module, one of the three Italian pressurized logistics modules, which enabled four tons of supplies and scientific experiments to be transferred to the SSI.

Launched on April 19, it landed at the Edwards Air Force Base in California on May 1, having completed 186 orbits, covering approximately 8 million kilometers in 285 hours and 30 minutes.

Libertà party during a rally in Rome

When Guidoni entered the SSI as the first European astronaut on board, he carried with him the Italian flag and the banner of the Presidency of the Italian Republic, delivered to him by the president, Carlo Azeglio Ciampi.

Passionate about ecological issues, Guidoni entered politics immediately after he retired from active space travel, standing as an independent on the list of Italian Communists for the 2004 European elections and became an elected MEP.

He served until 2009 as a member of the parliamentary group comprising the European Left and the Nordic Green Left.

As an MEP, he served on various committees and working groups in the area of industry, research and energy, climate change, environmental health and food safety. He was a member of the budget control committee and was involved in working towards better relationships with the United States and Japan.

He lost his seat in 2009, standing as part of a list entitled Sinistra e Libertà - Left and Liberty. His involvement with politics continued for four years until 2013, when he had disagreements with the leadership group in his party and decided to quit.

Nowadays, married with one son, he works to popularise scientific subjects through writing an broadcasting.

In 2009 he presented a radio programme entitled From the Sputnik to the Shuttle, in which he retraced the main steps of the space era, and in 2009 narrated the epic history of the Apollo lunar missions for another radio broadcast.

A book based on that show - From the Earth to the Moon - was published in 2011. Guidoni has also written numerous newspaper and magazine articles and written books for children about space and space travel.

The town of Acuto sits on a ridge in the Ernici mountains

Travel tip:

The town of Acuto, which sits on a ridge in the Ernici mountains about 40km (25 miles) northwest of Frosinone in Lazio and about 80km (50 miles) southeast of Rome, suffers harsh winters with regular snowfall but is a popular place for city dwellers looking for an escape from the summer heat because its position exposes it to cooling breezes.  The town developed in the fifth century when many residents of nearby Anagni fled there in the face of a barbarian invasion. The town has many churches, going back to the days when Agnani and Acuto were important towns in the Papal States.

Piazza Cavour in the centre of Agnani

Travel tip:

Anagni is about 15km (9 miles) by road from Acuto. During medieval times many popes chose to reside in Anagni, considering it safer and healthier than Rome. The town produced four popes, the last one being Boniface VIII, who was hiding out there in 1303 when he received the famous Anagni slap, delivered by an angry member of the fiercely antipapal Colonna family after he refused to abdicate. After his death the power of the town declined and the papal court was transferred to Avignon. The medieval Palace of Boniface VIII, is near the Cathedral in the centre of the town. Close by there is a restaurant named Lo Schiaffo - The Slap.
