Theory of Relativity
Maybe travelling in time is an interesting topic. Also the idea of the flow of time at high speeds is a difficult idea to understand. But did you know that in 1905, someone dared to think differently. He is Albert Einstein. Questions such as, what will you see if you are moving at the speed of light? Well, it is argued that light speed is the maximum speed that is available in the entire universe. The speed of light was calculated by Maxwell using the equations of Electromagnetic wave.
c=√(1/(ε_o μ_o ))
We were able to understand that anything that has speed travels a certain distance in space in amount of time.
Einstein argued that measurements done on physically observable quantity must be uniform in all inertial reference frame. The problem is there is no such as universal reference frame. This gives rise to the assumption that everyone is moving relative to one another. This would give rise to another claim that is, “measurements taken from one reference frame, will be different from measurements taken from other frame of reference”. This argument is absurd because it will mean that laws of physics were different for different reference frames. The theory of relativity holds to the fact that the laws of physics were the same for all inertial reference frames.
This will be eminent when we apply the concept of the Doppler Effect to sound. We know that whenever the source of the sound moves with a velocity V_s, with respect to the observer there will be a change in the measured frequency. Furthermore there will be more measurements that can be made depending on the observer. So how do we determine the real frequency of the sound emitted by the source?
Another instance is when we are on board a plane with some velocity Vplane and we fire a bullet the relative velocity of the bullet on an stationary observer will be;
V=Vbullet+Vplane
Which is correct in Galilean transformation. Now what if we turn on the headlight of a plane? Would it mean that the speed of light will be the velocity of the plane + the speed of light? (v=c) ?. Absolutely not, because this will violate the premise that, “the speed of light is constant in a vacuum”.
Clearly from the two instances there must be a different formula that will unify measurements made on different reference frame. This method is called transformation.
So let us create two equation that will unify measurements in these two instances. The first instance is at the plane, the observer at the plane will have (x,y,z,t). and the observer from the earth will us the coordinates (x^',y^',z^',t^'). So which is it the spaceship is moving away from the earth or the earth is moving away from the spaceship. To fix this, we assume that the origin O and O^'coincide and are parallel to one another at all times. Further more we let t and t^' be equal that is t= t^'.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
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.
