Visualisation is widely believed to bring many benefits, assisting us in making sense of all kinds of information. To try to make diagrams of history – using timelines or some other kind of chronographics – may seem a simple task. We might regard time as ‘obviously’ linear, as ‘naturally’ flowing from left to right. But what shape should history be?
Stephen’s talk focuses primarily on the period in the mid-eighteenth century when the modern timeline was invented – tracing its typographic, pictorial and other roots and setting it in its intellectual context. He also gives some insights into the advances we can now achieve when chronographics are made digital and interactive. This will include asking: what are the requirements of such tools for serious historical work?
Stephen Boyd Davis is professor of Design Research at the Royal College of Art. His own work is concerned with visualisation, in which he is directing research students working with museums and archives.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
Introduction to AI for Nonprofits with Tapp NetworkTechSoup

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

TALLY STICKS
▸ A tally stick was an ancient memory aid device
used to record and document numbers,
quantities, or even messages. Tally sticks first
appear as animal bones carved with notches
during the Upper Palaeolithic
▸ Tallies have been used for numerous purposes
such as messaging and scheduling, and
especially in financial and legal transactions, to
the point of being currency

LIBRARY OF ALEXANDRIA
▸ The Great Library of Alexandria in Alexandria,
Egypt, was one of the largest and most significant
libraries of the ancient world.
▸ It is unknown precisely how many papyrus scrolls
were housed at any given time, but estimates
range from 40,000 to 400,000.
▸ Despite the modern belief that the Library was
burned once and then destroyed, it actually
declined gradually over the course of several
centuries

JOHN GRAUNT (1620–1674)
▸ Along with William Petty, developed early human
statistical and census methods that later
provided a framework for modern demography
▸ In 1663, in his book Natural and Political
Observations Made upon the Bills of Mortality he
used analysis of the weekly statistics of deaths in
early modern London to create a system to warn
of the onset and spread of bubonic plague in
the city. Though the system was never truly
created, Graunt's work in studying the rolls
resulted in the first statistically based estimation
of the population of London.

HERMAN HOLLERITH (1860–1929)
▸ He was an American inventor who developed an
electromechanical punched card tabulator to
assist in summarizing information
▸ There were so many more inquiries of all kinds
in the census of 1880 that almost a full decade
was needed to publish all the results
▸ He developed a mechanism using electrical
connections to increment a counter, recording
information. A key idea was that a datum could
be recorded by the presence or absence of a
hole at a specific location on a card

FRITZ PFLEUMER (1860–1929)
▸ He was a German-Austrian engineer who
invented magnetic tape for recording data
▸ The principles he develops are still in use
today, with the vast majority of digital data
being stored magnetically on computer hard
disks.

LESSON 1
THE HISTORY OF DATA VISUALIZATION
▸ The term “Data Visualization” may have firm roots in the 20th Century, but the
concept of data storytelling is as old as time.
▸ The earliest data table in known existence was created during the 2nd century
in Egypt, cataloging astrological information to aide navigation practices of the
day.
▸ A table is a textual representation of data: a way to arrange information into
columns and rows for easier visualization.

WILLIAM PLAYFAIR (1759–1823)
▸ Playfair was a Scottish engineer and political
economist who published The Commercial and
Political Atlas in 1786.
▸ He is considered the father of statistical
graphics, having invented the line and bar
chart we use so often today. He is also credited
with having created the area and pie chart.
▸ Here he compares exports from England with
imports into England from Denmark and
Norway from 1700 to 1780.

FLORENCE NIGHTINGALE (1820–1910)
▸ Florence Nightingale is famous for her work as
a nurse during the Crimean War, but she was
also a data journalist.
▸ She realized soldiers were dying from poor
sanitation and malnutrition, so she kept
meticulous records of the death tolls in the
hospitals and visualized the data.
▸ Here we have an example of her coxcomb or
rose diagrams that helped her fight for better
hospital conditions and ultimately save lives.

LESSON 1
TABLE, BAR CHARTS AND COXCOMBS
▸ Coxcombs, just like bar charts or pie charts, are
graphical systems of representing data. They are
sometimes called polar area charts or roses.
(Despite many claims to the contrary, Nightingale
did not originally refer to the graphs as coxcombs).

JOHN SNOW (1813–1858)
▸ In 1854, a cholera epidemic spread quickly through
Soho in London. The Broad Street area had seen over
600 dead, and the remaining residents and business
owners had largely fled the terrible disease.
▸ Physician John Snow plotted the locations of
cholera deaths on a map. The surviving maps of his
work show a method of tallying the death counts,
drawn as lines parallel to the street, at the
appropriate addresses. Snow’s research revealed a
pattern. He saw a clear concentration around the
water pump on Broad Street, helping to find the
cause of the infection.

LESSON 1
CHARLES JOSEPH MINARD (1781–1870)
▸ Charles Joseph Minard was a French civil
engineer famous for his representation of
numerical data on maps. His most famous work is
the map of Napoleon’s Russian campaign of
1812 displaying the dramatic loss of his army
over the advance on Moscow and the following
retreat.
▸ You can see how many soldiers are still marching
and how many died. Drawn in 1869, it is
described by many as the best statistical
graphic ever drawn. It represents the earliest
beginnings of data journalism.

LESSON 1
EDMOND HALLEY (1656–1742)
▸ Edmond Halley was an English astronomer,
geophysicist, mathematician, meteorologist,
and physicist who is best known for computing
the orbit of Halley’s Comet.
▸ Halley developed the use of contour lines on
maps to connect and describe areas that
display differences in atmospheric conditions
from place to place. These lines are now
commonly used to describe meteorological
variation common to us from weather reports.

LESSON 1
CHARLES DE FOURCROY (1766–1824)
▸ Charles de Fourcroy was a French
mathematician and scholar. He produced a
visual analysis of the work of French civil
engineers and a comparison of the
demographics of European cities.
▸ In 1782 he published Tableau Poléometrique, a
treatise on engineering and civil construction.
His use of geometric shapes predates the
modern treemap, which is widely used today to
display hierarchical data.

LUIGI PEROZZO (1856–1916)
▸ Luigi Perozzo was an Italian mathematician and
statistician who stood out for being the first to
introduce 3D graphical representations,
showing the relationships between three
variables on the same graph.
▸ Perozzo published one of the first 3D
representations of data showing the age group
of the Swedish population between the 18th
and 19th centuries.
