but this is not einstein's equation. this is not what if it is this would mean if they said oh yes, i was thinking about einstein's equation earlier today. here's einstein's equation. as a physicist thinks about it. where you would say it out loud, it would be our muniu minus -- -- -- this is the field equation for the curvature of space time itself in general relativity. and we never tell you about this. we might give you the words, we might say, face time is curved, and the curvature is gravity, things like that. but we don't give you the equation unless you're a physics major, shut out two visits majors in here. but even then, most undergraduates never see this equation and they get a physics degree. it's considered to be too hard. there's all these greek letters in there, there's subscribes, we don't know what's going on. an hour from now, you will all know what's going on. i want to teach you this equation. how do we get there? we start with classical mechanics. the whole theme of book one is classical mechanics, as

so here is marshall grossman next einstein einstein sitting there as if he's a student again learningics of curved space time so what is that? what is the mathematics of curve space-time? there's a mstory that you migh have heard about the invention of non-euclidean geometry. there is euclidean geometry which is what we learned in high school is associated with things like pythagoras theorem, the area of the circle and most famously the parallel popular or most infamously, what euclid did back in the day when he really systematize the study of geometry most of the results we know about euclidean geometry whether people had already derived. what euclid did was systematize it by saying here is a set of axioms from which we can prove all these are the results. there's one axiom that stuck out as annoying. most of the axioms were pretty indisputable but there was one called the parallel Ãthat said the following thing if i take a little line segment and from that line segment i take two other line segments shooting out at right angles and we are little tiny line segments two other line seg

so here's marcel grossman next to einstein. einstein sitting there as if he's a student again, learning mathematics of curved space time. so what? that i know you're you're desperate to know what is the mathematics curved space time. there's story that you might have heard about the invention of non euclid in geometry. so there's euclid in geometry, which is what we learn in high school. it is associated with things like pythagoras theorem. the area of a circle is pi r squared and most the parallel postulate or most infamously what you could did back in the day. he really systematized the study of jiomart pre most of the results that we know about from euclidean geometry other had already derived. what euclid did was systematize it by saying here's a set of axioms from which we can prove all these other results. and there was always one axiom the kind of stuck out as annoying, like most of the axioms, were pretty indisputable, but there was one called the parallel postulate that said the following thing if i take a little line

einstein was. you got to imagine 1915 feverishly scribbling things down because by that time einstein bless his heart had given 20 talks on general relativity before he was finished firmly at the theory. everyone in germany knew this was the project to be worked on there is a brilliant mathematical minds working on i so we had to work fast. and he succeeded here is the answer. you take the tensor and subtract from its one half times the curvature scaler times the metric. those two things combined are still eight to index tester a four by four array. those seats proportional and you get the right answer. that is what physicists think of as einstein's equation. that is where we started. see, it was not so hard. [laughter] but we are not donee yet it got to tell you one more thing. what one does of coursee after one once one gets an equation like this one has a drink or something. but how do we know whether it's the right equation? you have to do solving the equation. this is an equation remember the

but this is not einstein's equation. it's not what a physicist would mean heavy settle yes, i'm thinking about einstein's equation earlier today. here's einstein's equation as a physicist thanks to that. were you to say it aloud could be armenia minus one half a minute makes a five t team in you. this is the field equation for the curvature of space time itself in general relativity. we never tell you about this. we might give you the words. space time is curve and the curvature is gravity things like that. but we don't give the a question less your physics major. shadowed to those physics major out there maybe again it. but even in most undergraduates never see this equation if they get a physics degree. it's considered to be two armed. there's all these greek letters in their, they're sub script, we don't know what's going on. an hour from now we will all know what's going on. i want to teach you this equation. how do we get? there we caught with classical mechanics. the whole theme a book one's classical mechanics as

albert einstein. he said look, i love my equation and that's beautiful and nobody will ever solve it and it's too hard to solve and how in the world can we solveth this equation? someone in the audience when he said that was carlos forth shield a german astronomer and physicist and mathematician serving in the german army at the time and it was world war i, 1917, and you had some shore leave and short shield deciding to go to the lectures of the academy during the leave and goes back to the front and his spare time says i can solve this equation and gets his solution. what hawkeyes does it mean to get a solution? equation means to get a form of the metric as a function of where you are. as a function of the coordinates in space time so so the question the short shield asked is what if i have an object like the sun and i idolize it so it's not spinning and not perfectly spear cal and -- spiracle and around is empty space and nothing is changing overtime. that's a dramatic amount of simplification and a

lemaitre went back and dug into einstein's theories.einstein's theory of equations of general relativity further and discovered that to the equations the universe either could be part contracting or actually expanding, and he was able to show that that in fact was what was happening. einstein didn't want to believe it because honestly, a priest telling that the universe a beginning. right. i mean, it actually hit actually to a certain felt too much like there was a hint of religious religiosity to it. but ultimately, einstein had to he looked at evidence and he changed his mind. lemaitre convinced him. and now that's the big bang theory. when we when we say the hub of the james webb telescope shows us images, the early earliest universe, 13.8 billion years ago. we know that we now accept the theory that lemaitre brought forward. and it's one of many stories in the book of of new theories we now consider groundbreaking that at the time were just very, very well respected scientists wouldn't consider because were just too weird. how could

natalya ryabchikova podcast from einstein 125. goodbye. all the best. lord

first round we are all beans, when we get to this topic i will explain what it means albert einstein hospital in translation not only birds and eureka michael choice your three hundred, please, this particular gift of friends was built for einstein by special order and was named tuner porpoise. albert's yacht bureau in berne became the first place of work of the einstein patent office with the initiative of you repeat for 300 topics. repeat all the answers in this thread consist of the same parts, for example, baden-baden or barbarian. according to the dictionary of russian personal names, this name can be a diminutive of olga's eulalia and even alike. maybe lyalya albert 200, please einstein was friends with this world chess champion and later recognized him as one of the most interesting people among his acquaintances. maybe to him, well, lascar is true. repeat for a 200 symphony orchestra, this instrument doesn't look much like a drum. it sounds in sheher behind the rim-korsakov and in the finale of the sixth symphony of tchaikovsky and in the billini norm. it's absolutely right t

i think that christopher nolan took liberties with einstein. he had him play a bigger role than he actually did. he had oppenheimer ask him to do the calculations as to whether the air would be ignited by the blast. that was not the case. einstein was visited in long island in august of 1938 to sign a letter to roosevelt, warning him of the german efforts. so he famously gets credit for getting th rolling and getting the united states and the president to start this effort. but after that he did not go to los alamos, he did not play a big role. his equation was the fundamental principle of hind the atomic bomb. so his shadow was everywhere. but he was not. after the war, he was at princeton, at the institute for studies that oppenheimer was director of. so he and oppenheimer spent more time after the war when they were together there. but whether jewish scientists and their role in the manhattan project were vilified, that is hard to say. i think not particularly because all of the purchase pence were secret. the american public was not told wh

studies, professor einstein , after that, the hyena will introduce a great movie , they are showinginemas of the world , so that germany can do this. i will start studies, studies will be done, reza's chest is 110, approximately 44, i will conduct the first test in surrey, new mexico, in a limited way . this is news. what is this news? we tried the atomic bomb, it can't be calculated better than this, how many people will be killed when it explodes, disabled people, and we have ankara, we have time, we can say that in fact, i wanted to test it with my own rope, which the truman american government, contrary to the day , did not agree, a very person. he was a gentleman, he thought that the bombing of german cities allowed the atomic bomb to come , but you have to do this, our teenagers will be killed, this is going to hiroshima on the sixth day, the sky of this pilot, who i told him, when the bomb is dropped, look and see what happens . there is an effect of shooting and filming mannequins excuse me, where is the capital of japan? i will tell you that there were 70,000 people in 1963

it's so interesting that it's a very funny answer of einstein's.e him a letter that says and well , he argued because he contradicted but to say but a very elegant version that a cat is one thing but there is and that means i say no i agree but it is very elegant and there is a cat and there is no one yes yes and when we need it there is when we need it there is no one that can hurt the fate of the one who is not there although they have to conclude a contractual change of defense , that is, there is no escape, but there is a contract and there is a contract , but she is not brought, but there is absolutely no by the way, always and maybe it wasn't okay, we went up the mountain to the studio excuse me, please so yes, we are regular guests yes, we have guests pain can become an obstacle on the stairs not with my knees from knee pain try dolegit cream dolegit cream relieves pain, reduces swelling and improves mobility of the joints is also possible on foot dolgit is the only yellow cream for pain in the joints and for muscle spasms dolgit antisum pil

i think that christopher nolan took a couple of liberties with einstein. he hadn't played a bigger role than he actually did. he at oppenheimer ask him to do the calculations as to whether the air would be ignited by the blast at trinity that wasn't the case here einstein was visited in long island in august of 1938 to sign a letter to roosevelt warning him of the german effort. so he famously gets the credit for kind of getting the ball rolling andetng the united states and the president to start this effort. but after that he didn't go to los alamos. he didn't play big role. is equation e equals mc square was at the fundamental, is a fundamental principle behind the atomic bomb. so his shadow was everywhere but he wasn't. after the war he was at princeton at the institute studies that oppenheimer was then director of. so he and oppenheimer spent more time after the war when they were together at princeton. with respect to whether jewish scientists because of the rope in the manhattan project were vilified, that's hard to say. i think not particularly bec

and the real soviet director and student from einstein vladimir vengerov could play real, other characters appear there. they are in the script even more important than end up on the screen. they were also muted in the script , an incredibly important character appears. actually, the screenwriter, who was clearly written off with gabrilovich, and began to talk about the fact that gabrilovich is a person. even in the twenties and thirtieth, he came actively to the cinema. he is a very interesting writer. he started in general as a musician, he is a master, and from the point of view of a master, he is such a character. olya gabrionovich appears scripts. he protects our heroine pasha stroganova, whom the director took on the role of joan of arc, and someone does not believe. let's look at the fragment. let's. well, something else, in my opinion, the situation is terrible. and i think it's great. well i do not know. even begged, not brothers for the lead role. and i'm sick, look at the faces. it's not about that. call it jeanne d'arc some kind of hooligan. i, as the author of the insistence s

einstein clicked back because physics is easier than politics we are now in the realm of you can whatically lay out that was the approach of the book it's not hard advocacy book and what would be the prerequisites for policymakers to make decisions such as the one reflected in the question which is a great one i'm not sure the 750 number would be locked t in by i think the concept the concept is analytically valid where the politically we can get there or not i think is the question. >> all right. we are in the room. >> hi, my question is regarding like the deployment of tactical nuclear weapons in ukraine by russia many china experts and alice say ÃÃthat would be the redline for beijing because according to the corian foreign policies nuclear weapons should be used for deterrents not attack another country but also like territorial integrity should be one of the ÃÃwe see that's not the case since they been aligning with russians existing vision of ukraine i was wondering first if you think that china would indeed side with the west if russia deploys nuclear weapons in ukraine and sec

einstein clipped back because it's easier than politics we are now in the realm of you can adequately that was the approach in the book it's not a hard advocacy book is trying to lay out the analytical landscape and where the debates are and what would be the prerequisites for policymakers to make decisions such as the one reflected in the russian which is a great one i'm not sure the 750 number would block into it but i think the concept the concept is analytically valid the politically we could get there or not i think is the open question. >> we are in the room and i'm going to take this out here, that's you. >> hi, robert, my question is regarding the deployment of tactical nuclear weapons in ukraine by russia. many china experts and analysts say that if ÃÃthat would be redline for beijing because according to the core principles like foreign policy nuclear weapons should be used for deterrence since they have been aligning with russia's existing vision of ukraine i was wondering first if you think that china would indeed side with the west if russia provides nuclear weapons in uk

culture our culture is very much invested in the idea of the sort of the solitary genius, you know einsteinand john lennon and picasso and and often if you really look at it einstein was had a mentor who influenced them. john lennon had paul mccartney. you can go through the whole list. so part of my interest in writing the book was the relationship between the two of you and the friendship and to partnership. frank, do you have any thoughts about that? yeah, well, i met mark for the first time. i was selling one machine, maybe. every ten days and. bart being the marketing guy, the first six months after i hired him and i hired him on a straight commercial and, i couldn't afford to pay him. he sat in my office and watched me try to sell the machines and that six month period, remember, he made a phone call to, a company in canada that they were was actually a monro muffler. they make the sell mufflers. you know, munro munro muffler and bart went up well. he came home with an order for 100 machines and that was just mind blowing 100 machines in one order. and that's really got us started so

einstein quipped back that is because physics is easier than politics.n we are now in the realm -- mccueould analytically lay out. that is what we approach and the buckets on a heart advocacy book it's from it analytical landscape. and what would be the prerequisite for policymakers to make decisions such as a one a great one but i'm not sure the 750 number is the one locked and it would be a higher number. i think the concept is nanalytically invalid whether politically we can get that were not is the open question. looks okay, all right we are in the room. i'm going to take it right down here. yes that's you. >> hi robert, i was a fellow here. now i'm u.s.di correspondence. my question is regarding deployment of tactical nuclear weapons in ukraine by russia. many china expertsts say deployg tactical nuclear weapons in ukraine that will be the redline for beijing. because according to the core principles ofei foreign nuclear weapons should be used for deterrence not to attack another country. but also was supposed to be one for the chinese as well but we see that's not thehe case. they

open societies of george soros, the international republican institute in the world and the albert einsteinute are based, where are they based in belgrade? quite simply on the spot at the crime scene. it is based on the george soros open society foundation one of the world's largest international charitable organizations initiates and supports programs in the field of education , culture and arts of civil health, initiatives whose stated goal is to develop ideas and mechanisms open society. you remember how much this organization put on in the world. this organization actively sponsors ngos not government organizations. do you know what budget is more than 19 billion? 19 billion us dollars, you add up the numbers , let me remind you of whom this philanthropist grew up . as a boy, together with his father in german-occupied hungary, he helped describe the property confiscated from the jews. as far as i know, you had a patron who presented you as your adopted son and you went out with him to help seize jewish property. yes it is. but after all , such an experience can drive a psychiatrist on

so refugee scientists like albert einstein and enrico ferdme played a key role in the development of nuclear physics in this country. and the united states also went to great lengths to bring in people that they considered the brightest into the united states. and as we discussed a couple of weeks ago the secretary of state even expunged the nazi records of people like werner von brown and some of his fellow nazi scientists so that they could work in us intelligence. and verna von braun and his fellow his team of scientists played a key role in the development of the us space program. but refugees also informed our political life. think of henry kissinger madeleine albright the german political theorist hannah arendt they have played a key role but there are others they've played a cube role in shaping our political life. they've shaped our cultural life think of the actress, marlena dietrich. the hungarian composer bella bartok the austrian composer arnold stormberg and the russian french painter mark sagal but there are many many other refugees that we could highlight refugees have

said i feel at the -- much as i did 50 years ago except that i am much happier, as he told lewis einstein, one of his many considerably younger friend. he bounded up the stairs to his study to at a time and begin each day with a bracing cold bath the practice he carried on through age 88 when he finally gave it up for a warmer bath at that time. as often noted as his mental and physical vigor, was his extraordinary embodiment of the sweep of history. as a union officer in the civil war, he had barely escaped death in antietam when musket balls tour through his chest and neck, missing his heart, spine and carotid artery by an eighth of an inch. he had spoken to grant, shaken hands with mead at spotsylvania, seen lincoln dog -- dodge and we fire during the raid on washington. he knew ralph waldo emerson as a family friend and dimly remembered hermann melville as a summer neighbor as a gruff and taciturn man. traveling europe after the war, he climbed the alps with -- alps with leslie stephen, later known as the father of virginia woolf, and in law school he became fast friends with henry ja

this theory can be proved to be the most important scientific achievement since albert einstein's theory of relativity until now . 800 grams to one kilogram, while researchers were able to grow watermelon in the pole , which is a tropical fruit and needs a lot of heat to grow , climate change has been effective in reducing the number of elephants , threatening the loss of habitats for the survival of the films. according to a television reporter let's meet al jazeera english here . al-spicy poaching has put the elephants in danger . with 50,000 tomans, they are in greater danger in the wild. the executive director of the film support center says that the number of elephants is facing many threats, what factors have caused us to lose what we have and what can be done which we have to preserve and ensure that the number of elephants decreases it's coming. one of the things we've seen is the decline of elephants just because of climate change. we 've been talking about poaching for a few years now, but i'm happy that most african countries, including kenya, tanzania, and andar, have been ab

no one had einstein in mind, it should be pasted pasted all this what is the attitude to physics, physicsnot, but show the pass. where to go it's not right clothing has nothing to do with it has nothing to do with omissions it annoys relations geography has nothing to do with. well, this is some kind of status sign status sign, well, remotely, but i would not go to yours. yes, it will lead to the wrong place at the conference , they hang badges that i am like that, you are like that, here now yes ticket no for a ticket it's not a ticket. maybe it's a blood type, it's not a pass. it's not what the word is passport. this is not a passport. give two questions in a row passport, passport. we decided around passports. yes, these are what the third hint is, and you will be . no, it has to do with love. well, yes, this is valentine. this is not a valentine, this is a postcard. so look. what does the question sound like to you. it’s just that now it’s not clear that this is what the invitation to a date is for. similar to a wedding invitation. well , that is, well, for what in other words. well t

this theory the proof can be the most important scientific achievement since the time of albert einstein's theory of relativity, the winners of the 14th science and nanotechnology student olympiad have been announced. the final third stage of the olympiad was held for 12 days at iran university of medical sciences . in 2010, the poet decided to register in the olympiad and the first and second stages were held in the form of a theory test, and a student made it to the final stage of the olympiad. this time, instead of solving theoretical problems , they had to produce medicine in the laboratory of iran university of medical sciences. this for 12 days, they tried to synthesize a nano drug in the laboratory and check the release of the drug and its effect on the treatment of cancer . the company is from the city of saqez, kurdistan province, and in different ages and eleventh grade, the teacher's experimental field, the students of the tenth and eleventh grade, the eleventh grade, the twelfth grade, the experimental grade, the seventh grade, the experimental grade, the twelfth grade , are no

the initiator of the expulsion albert einstein children's germany, with his sanction, the best german, communists and social democrats of the violent nation, were executed. that was the name of the debes in the party, however, the apparatus of richter himmler in his secret reports called the reich minister. otherwise, it passed under the coded designation bodelberg steer several times secret agents of the gestapo spotted the reich minister in the boudoir of actresses in babelberg during night orgies, but scandals erupted when it became known about goebbels' passion for the czech actress. lida barr gebbez was summoned to the party office and for four hours was forced to give humiliating explanations about his connection with an inferior slav shortly after these events, which almost cost goebels, stirlitz saw the minister's nut at a book fair. he remembered geras' hands. goebbels handled the book of selected speeches of goebbels with care. that same night , the books were burned by order of the hybris. max engels hegel kant heine mann tolstoy brecht zaggers and many other ministers cont

what did you understand there einstein enough that you don’t have a furnace in the full program in thece of gangsters, can you imagine, newspaper headlines. and so you're blackmailing me, or something, glebushka and you don't doubt it. wait, i won’t be silent, you won’t let everyone know about your business, they don’t know the amount at 5:00 in the evening, not in rubles. yeah, my friend, you don’t need to bring down the cop without focus. is he right now? well, at the beginning of your sum i will not put more than a three. i have enough money. bring vyshnegorsk tomorrow. urgently a doctor for a living well, please, well, please, please, we all pass on, we pass. goodbye. well, what did you see with him? i told you, you shouldn't have gone . they don't allow a date. they just don't let him in at all. medical unit normal condition is heavy, it seems that he will live. why like this. listen, you only know him. come on, calm down. i'm with the guys now, got it? let's all get in touch. the dos information has been confirmed. sasha is sitting in a common cell ; they tried to kill him with a

i would say so, maybe everyone noticed him, but einstein, by the way, said, that the main thing is toong answers, but to ask the right questions. this question is read in the fact that the president is already directly hinting in the question of what will happen to ukraine, how it should change in order to preserve it twice or thrice. yes, you brought to the topic that you ukrainians need to start everything from scratch, you need to change everything, you need to change your entire politics and economy, and so on and so forth. that is, he says that in ukraine there should be some new force capable of betraying her life. otherwise it ukraine will perish. and this life is her future. it needs to be completely reformatted. ukraine must turn for anti rus and anti belarus into a friendly country for us in terms of both justice and how the president says that the poor must be protected. yes, look at them not only at the oligarchs and so on, that is, change the entire structure and political and economic life of ukraine half a million people in the land. this is not yet a meat grinder meat

even the most unprepared, and this was the tip of einstein's witnesses where two film historians arebchikova and my colleague. stanislavsky we talk about how by whom why were the classics made? unknown cult famous unseen soviet films we are trying to help modern viewers to watch these films with great interest, great understanding and great pleasure. see you again. thank you, see you on the screen. hello dear friends in the crocodile magazine in the seventy-ninth year was such a joke was published. uh, the boy goes up to his father for the new-haired man, who is carelessly strumming the guitar and asks dad. and what will you be when you grow up gentlemen? this is the resurrection group. today i am 45 years old lord , look how you have grown and look at yourself, dear friends. i am convinced that my generation will now cling to the screens and let's remember what happened when the trees were large group resurrection fell that the day will shut up life in a strange way. and your house became lonely. and it's empty outside your window and the light is dead and the sounds are getting wet
