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
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.
2. Classification
Science of arranging organisms in
series of groups and subgroups on the
basis of their similarities and
dissimilarities.
Aristotle classified organisms on
the basis of their habitat means the
place where they live, in water, in air
and on land.
3. Basic characteristics of
classification
• Nature of Cells: prokaryotic or
eukaryotic
• Cellularity: unicellular or multicellular
• Level of organization:
cellular, tissue, organ and organ system
• Mode of nutrition: autotrophic or
heterotrophic
4. Classification and Evolution
• Time is the key factor which helps in
development of complex organisms from the
simple ones.
• Charles Darwin firstly gave the idea of evolution
in 1859 in his famous book ‘The Origin of
Species’.
• Those organisms which have ancient body design
and not changed much are called Primitive
organisms.
• Those who acquired certain special characters
during the time period are known as advanced or
higher organisms.
5. Biodiversity
• Biodiversity is the term used for the various
forms of life found in a given area.
• These life forms depends on each other and
on the environment and results in a stable
community.
• Human also is the part of this biodiversity.
• It is estimated that there is about
10,000,000 species on this planet, we know
only about 20,00,000 species.
6. Hierarchy of classification
• Ernst Haeckel, Robert Whittaker, Carl Woese
have tried to classify all living organisms into
broad categories.
• R. Whittaker proposed five kingdom system
which is widely used. This kingdom includes
Monera, Protista, Fungi, plantae and Animalia.
• Carl
Woese
divided
Monera
into
Archaebacteria and Eubacteria.
7. Further classification
Further classification is done by naming the sub
groups at Various levels as given:
Kingdom→PhyllumDivison→Class→Order
→Family→Genus→Species
•Kingdom

are
covered
by
mucilage.

by
vegetative, asexual and
sexual reproduction.

body
is
differentiated
into
leaf, root and stem like
structures.
• Special conducting tissues
are not present.

amphibians
of
plant
kingdoms.
• Reproduce
by
vegetative, asexual and
sexual reproduction.
• Funaria, Anthoceros and
Marchantia
are
few
examples.
14. Divison: Pteridophyta
• Plant body is differentiated
into leaf, stem and roots.
• They also have conductive
tissues.
• All the above discussed
plant types doesn’t bear
seeds instead they bear
spores. They are also known
as cryptograms.
• They require water for the
purpose of reproduction.
• Fern,
Adiantum
and
Selaginella.are
few
examples
15. Divison: Gymnosperms
• These plants bear naked
seeds mean seeds are not
enclosed in fruits.
• These
are
perennial, evergreen trees
having woody trunk.

largest tree found on earth
(125 Meters) is an example.
Other
examples
are
Pinus, Cycas.
16. Divison: Angiosperms
• Bear seeds covered by
special organs known as
fruits.

reproductive organs.
• Embryo in seed has special
structure called cotyledons
which act as seed leaves at
the time of germination.

groups:
Monocots
and
Dicots.

33. Need for Nomenclature:
• To solve the problem of many names for any
organism in different areas. Such as Lady
Finger (Abelmoschus esculentus) is known by
Bhindi, Gumbo in different countries.
• To solved out the confusion occurred by the
common names of some organisms. Such as
Silver fish, Cuttle fish are example of
arthropods and mollusks respectively, but the
name produce confusion that they belongs to
class Pisce.
34. How to write Scientific
Names
• Carlous Linnaeus introduced the system of providing
unique names to each organism.
• Few rules are proposed for naming that are following:
1. Name should be given in Latin language.
2. Name of Genus begins with capital letter.
3. Name of the species begins with small letter.
4. The scientific name should be written in italics when
printed and should be underlined separately when
hand written.
• Such as the name for Humans is “Homo sapiens”,
for Lion is “Panthera leo”.
