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
Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.

LED Lights Introduction
1. Basic Things to Know about LED Lamps
Performance is the result of 3 groups of components
Optical LED components
perceived to deliver the same or better light effect as the original light source
(beam shape, intensity, color point, color rendering),
and perceived as equal or better light quality - variation between lamps
Electrical LED components
need to be 100% compatible with the electrical input power characteristics
and 100% compatible with installed accessories (dimmers, transformers),
while causing no non-compliances.
Mechanical & thermal LED components
mechanical compatibility (shape, size) into an existing socket & fixture
and thermal compatibility into existing socket & fixture

2. Color Binning
Metal Halide
HPS
CIE Chromaticity Diagram
• Each color consists of several different “bins”
• The performance of each LED is unique
• Each LED is binned by three measurements:
output
color

power

3. Binning
All LED Components In A Product Batch Are Different
Manufacturing Inspection & QC Sorting a.k.a. Binning
• Higher output bins cost more Cool
• Bins closer to the black body curve (“whiter”) cost more
• Manufacturers will not sell you just one bin in large volumes
• Manufacturers will not guarantee availability of specific bins
Warm
High Output
Low Output

4. Light Quality
LEDs and Standards
Methods for Achieving Good Quality Light
• Use only one LED bin
• LED Binning Algorithms
• Optical treatments to reduce variation
• Fixture Calibration

Philips LEDs
Philips Optibin’s CCT and hue tolerances for LED’s fall within a 4-step
MacAdam ellipse , rather than 7-step ellipse defined by ANSI standard
Optibin dictates the use of LED’s from bins which lie close as possible
to the black-body curve within the 4-step ellipse. This proprietary algorithm
intelligently combines LED’s from different bins, guaranteeing color
uniformity for lamps purchased and shipped at different times
SDCM – Standard Deviation of Color Matching
A color difference of 1 SDCM “step” is not visible
2 – 4 “steps” is barely visible
5+ readily noticeable
