More than just a name. Physicist. Genius. Science pop star. Philosopher and humanist. Thinker and guru. On a par with Copernicus, Galileo or Newton. And: Albert Einstein – from Ulm! The most famous scientist of our time was actually born on 14th March 1879 at Bahnhofstraße 20 in Ulm. Albert Einstein only lived in the city on the Danube for 15 months. His extended family – 18 of Einstein’s cousins lived in Ulm at one time or another – were a respected and deep-rooted part of the city’s society, however. This may explain Einstein’s enduring connection to the city of his birth, which he described as follows in a letter to the Ulmer Abend- post on 18th March 1929, shortly after his 50th birthday: “The birthplace is as much a unique part of your life as the ancestry of your biological mother. We owe part of our very being to our city of birth. So I look on Ulm with gratitude, as it combines noble artistic tradition with simple and healthy character.” 8 9 The “miracle year” 1905 – Einstein becomes the founder of the modern scientific world view Was Einstein a “physicist of the century”? There‘s no doubt of that. In his “miracle year” (annus mirabilis) of 1905 he pub- lished 4 groundbreaking works along- side his dissertation. Each of these was worthy of a Nobel Prize and turned him into a physicist of international standing: the theory of special relativity, the light quanta hypothesis (“photoelectric effect”), Thus, Albert Einstein became the found- for which he received the Nobel Prize in er of the modern scientific world view. -
A Study of Gravitational Wave Memory and Its Detectability with LIGO Using
A Study of Gravitational Wave Memory and Its Detectability With LIGO Using Bayesian Inference Interim Report #2 Jillian Doane - Oberlin College Mentors - Alan Weinstein and Jonah Kanner LIGO Document T1800230 LIGO SURF 2018 July 31, 2018 Update For Interim Report #2 I have made significant progress since my first interim report. I have accomplished the next steps I outlined in my previous interim report and I am also on track with the project schedule I made at the beginning of the year. So far I have met my expectations for the summer, and I am continuing to think about the next best step for my project. I have run into a few additional challenges since my last report. I have continued to have some issues with getting my code to work so I have had to take a substantial amount of time to debug. From this however I have built my intuition in regards to programming with Python which will be very beneficial for future projects and research. I have continued to use the same resources, mainly my mentors, tutorials, and the internet to answer questions and understand key concepts. The next step I am currently working on is creating a loop that will allow me to input a set of distance and mass parameters and plot them on the same graph. From here I will calculate the 90% confidence interval so I will be able to communicate how confident we are that lambda is equal to one. This calculation will also hopefully show that zero is not included at all in the peak which means that there is a very low probability that memory does not exist. -

Albert Einstein - Wikipedia, the free encyclopedia Page 1 of 27 Albert Einstein From Wikipedia, the free encyclopedia Albert Einstein ( /ælbərt a nsta n/; Albert Einstein German: [albt a nʃta n] ( listen); 14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the theory of general relativity, effecting a revolution in physics. For this achievement, Einstein is often regarded as the father of modern physics.[2] He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect". [3] The latter was pivotal in establishing quantum theory within physics. Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity. He Albert Einstein in 1921 realized, however, that the principle of relativity could also be extended to gravitational fields, and with his Born 14 March 1879 subsequent theory of gravitation in 1916, he published Ulm, Kingdom of Württemberg, a paper on the general theory of relativity. He German Empire continued to deal with problems of statistical Died mechanics and quantum theory, which led to his 18 April 1955 (aged 76) explanations of particle theory and the motion of Princeton, New Jersey, United States molecules. He also investigated the thermal properties Residence Germany, Italy, Switzerland, United of light which laid the foundation of the photon theory States of light. In 1917, Einstein applied the general theory of relativity to model the structure of the universe as a Ethnicity Jewish [4] whole. -
Controversies in the History of the Radiation Reaction Problem in General Relativity
DIVISION OF THE HUMANITIES AND SOCIAL SCIENCES CALIFORNIA INSTITUTE OF TECHNOLOGY PASADENA, CALIFORNIA 91125 CONTROVERSIES IN THE HISTORY OF THE RADIATION REACTION PROBLEM IN GENERAL RELATIVITY Daniel Kennefick ,.... 0 ...0 HUMANITIES WORKING PAPER 164 August 1996 Controversies in the History of the Radiation Reaction problem in General Relativity Daniel Kennefick* 1 Introduction Beginning in the early 1950s, experts in the theory of general relativity debated vigorously whether the theory predicted the emission of gravitational radiation from binary star systems. For a time, doubts also arose on whether gravitational waves could carry any energy. Since radiation phenomena have played a key role in the development of 20th century field theories, it is the main purpose of this paper to examine the reasons for the growth of scepticism regarding radiation in the case of the gravitational field. Although the focus is on the period from the mid-1930s to about 1960, when the modern study of gravitational waves was developing, some attention is also paid to the more recent and unexpected emergence of experimental data on gravitational waves which considerably sharpened the debate on certain controversial aspects of the theory of gravity waves. I analyze the use of the earlier history as a rhetorical device in review papers written by protagonists of the "quadrupole formula controversy" in the late 1970s and early 1980s. I argue that relativists displayed a lively interest in the historical background to the problem and exploited their knowledge of the literature to justify their own work and their assessment of the contemporary state of the subject. This illuminates the role of a scientific field's sense of its own history as a mediator in scientific controversy. -

MITOCW | 17. Gravitational radiation II [SQUEAKING] [RUSTLING] [CLICKING] SCOTT OK. Let's move on to the next lecture. Might have gotten a little bit of me getting HUGHES: prepped here. I really have to give a lot of credit to the people in the Office of Digital Learning for making this entire thing possible. So I'm really grateful particularly to Elaine Mello, who is at home running the show remotely right now. This is-- a lot of people at MIT are doing a tremendous amount to keep this place functioning, and everyone really deserves a huge pat on the back. All right. So in the lecture that I just completed a few moments ago, we described-- I described how to characterize the gauge-invariant radiative degrees of freedom, which we call gravitational radiation. With gravitational radiation, we found at the end-- there's a formula that I will write down again a little bit later in this lecture, but we essentially found that it looks like certain projections of a term that involves two time derivatives of the quadrupole moment of a source. This has in recent years led to a-- well, we've now been able to directly measure this form of radiation. I'm wearing my LIGO hat in honor of the facility that first directly measured these things. And we have inaugurated an entirely new field of observational astronomy based on being able to measure those things. It's pretty exciting. I hope, though, that a few people noticed how restricted the analysis that I did is. -

Einstein demonstrates that the linearised vacuum field equation admits wavelike so- lutions which are rather similar to electromagnetic waves 1918 A. Einstein derives the quadrupole formula according to which gravitational waves are produced by a time-dependent mass quadrupole moment 1925 H.

This illustration shows the merger of two black holes and the gravitational waves that ripple outward as the black holes spiral toward each other. The black holes—which represent those detected by LIGO on December 26, 2015— were 14 and 8 times the mass of the sun, until they merged, forming a single black hole 21 times the mass of the sun. In reality, the area near the black holes would appear highly warped, and the gravitational waves would be difficult to see directly.
