1) Newton reasoned that the moon and an apple fall due to the same force - Earth's gravity. The moon is falling toward Earth but has enough sideways velocity to remain in orbit.
2) Newton's theory of universal gravitation confirmed that gravity extends throughout the universe and follows an inverse-square law, decreasing in strength with distance.
3) Ocean tides are caused by differences in the moon's gravitational pull on opposite sides of Earth, with spring tides occurring during a new or full moon.

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.

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.

4. Spring tide(p. 247) is a high or low tide that occurs when the sun, Earth, and moon are all lined up.
5. neap tide (p. 247) occurs when the moon is halfway between a new moon and a full moon, in either direction.
6. Black hole (p.249) Gravitation near these shrunken configuration are called black holes, is so enormous that nothing can get back out.

15. When a quantity varies as the inverse square of its distance from its source, it follows an inverse-square law. For example, the inverse square of 3 is (11/3)2, or 1/9.

17. 13.6 gravitational Field Iron filings sprinkled over a sheet of paper on top of a magnet reveal that shape of the magnet’s magnetic field. The pattern of filings shows the strength and direction of the magnetic field at different locations around the magnet. Earth is a giant magnet and, is surrounded by a magnetic field.
18. 13.6 Gravitational Field The strength of Earth’s gravitational field, like the strength of it force on objects, follows the inverse-square law. Earth’s gravitational field is strongest near Earth’s surface and weaker at greater distances from Earth.
19. 13.7 Gravitational Field Inside a Planet The gravitational field of Earth at its center is zero! The gravitational field of Earth exists inside Earth as well as outside. If you traveled through an imaginary hole drilled completely through Earth you'd gain speed as you fell from the North Pole toward the center of Earth, and lose speed moving away from the center toward the South Pole.
20. 11.8 Weight and Weightlessness Pressure against Earth is the sensation we interpret as weight. The force of gravity, like any force, causes acceleration. Because we are almost always in contact with Earth, we think of gravity primarily as something that presses us against Earth rather than as something that accelerates us.
21. 11.8 Weight and Weightlessness If you stand on a scale, gravity pulls you against the supporting floor and scale, and the floor and scale push upward on you. This pair of forces compresses a spring-like gauge inside the scale. The weight reading on the scale is linked to the amount of compression. Weightlessness is not the absence of gravity; rather, it is the absence of a support force. Astronauts in orbit are without a support force and experience weightlessness.
22. 13.9 Ocean Tides Newton showed that the ocean tides are caused by differences in the gravitational pull of the moon on opposite sides of Earth. The moon’s gravitational attraction is stronger on Earth’s oceans closer to the moon, and weaker on the oceans farther from the moon. This difference causes the ocean to bulge out on opposite sides of Earth. Because Earth spins, a fixed point on Earth passes beneath both bulges each day, producing two hig tides and two low tides.
23. 13.9 Ocean Tides A spring tide is a high or low tide that occurs when the sun, Earth, and moon are all lined up. The tides due to the sun and the moon coincide, making high tides higher than average and low tides lower than average. Spring tides occur during a new or full moon. A neap tide occurs when the moon is halfway between a new moon and a full moon. The pulls of the moon and sun are perpendicular to each other. As a result , the solar and lunar tides do not overlap, so the high tides are nat as high and low tides are not as low.
24. 13.10 Black Holes When a massive star collapses into a black hole, there is no change in the gravitational field at any point beyond the original radius of the star. Two main processes occur continuously in stars like our sun: gravitation, which tends to pull solar material inward and thermonuclear fusion, which blows material outward.
25. 13.10 Black Holes If the fusion rate increases, the sun will get hotter and bigger; If the fusion rate decreases, the sun will get cooler and smaller. When the sun runs out of fusion fuel (hydrogen), gravitation will dominate and the sun will start to collapse into a black dwarf. For stars more massive than the sun, once thermonuclear fusion ends, gravitational collapse will take over, eventually forming a black hole. The density of a black hole is so grat that its enormous gravitational field prevents even light from escaping. The gravitational field beyond the original radius of the star in no different after the collapse than before.
26. 13.11 Universal Gravitation The formulation of the law of universal gravitation is one of the major reasons for the success in science that followed, for it provided hope that other phenomena of the world might also be described by equally simple and universal law. Earth is round because of gravitation, Earth attracted itself together before it became solid. Any “corners” of Earth have been pulled in so that Earth is a giant sphere.
27. 13.11 Universal Gravitation The solar system began when a slightly rotating ball of interstellar gas contracted due to mutual gravitation. To conserve angular momentum, the rotational speed of the ball of gas increased, causing the particles to weep out into a disk shape. The deviation of an orbiting object from its path around a center of force caused by the action of an additional center of force is called a perturbation.
28. 13.11 Universal Gravitation The planet Neptune was discovered when a perturbation in the orbit of Uranus led scientists to conclude that a disturbing body beyond the orbit of Uranus was the culprit. According to current scientific understanding, the universe originated and grew from the explosion of a primordial fireball some 13.7 billion years ago. This is the “Big Bang” theory of the origin of the universe. All the matter of the universe was hurled outward from this event and continues in an outward expansion.
29. 13.11 Universal Gravitation More recent evidence suggests the universe is not only expanding, but accelerating outward. It is pushed by an antigravity dark energy that makes up a estimated 73 percent of the universe. Twenty-three percent of the universe is composed of the yet-to-be discovered particles of exotic dark matter. Ordinary matter makes up only 4 percent.
30. Concept Summary Newton reasoned that the moon is falling toward Earth for the same reason an apple falls from a tree- They are both pulled by Earth’s gravity. The moon is actually falling toward Earth but has great enough tangential velocity to avoid hitting Earth. Newton’s theory of gravity confirmed the Copernican theory of the solar system. Newton discovered that gravity is universal.
31. Concept Summary Gravity decreases according to the inverse-square law. Earth can be thought of as being surrounded by a gravitational field that causes objects to experience gravitational forces. The gravitational field of Earth at its center is zero. Force against Earth is the sensation we interpret as weight.
32. Concept Summary The ocean tides are caused by differences in the gravitational pull of the moon on opposite sides of Earth. When a massive star collapses into a black hole, there is no change in the gravitational field at any point beyond the original radius of the star. The formulation of the law of universal gravitation provided hope that other phenomena of the world might also be described by equally simple and universal laws.
