Daf Yomi Eruvin Daf 56 by R’ Eli Stefansky

good morning rough voice how's everybody doing uh what is it it's telling you today first day after halloween no it's not about the other sunday sunday morning sunday morning show second day we gotta get our mindset here we happen to be in our straw first day of calamari but in reality we are in chicago live in chicago 11 15 in the morning we had a wild night last night we had two shoe room uh the second one ended 1am it was amazing the sacrifice now is the sacrifice that the it's actually the same people that were that are here this morning were here until one when we finished last night 1 15 in the morning i have to tell you also i just realized as as a magician there's um there's also a little sacrifice i'm not gonna go into all the sacrifice but one thing that really bothered me is i bought a brand new suit for you know most of my stuff in there as well i was all excited i found a great suit and i was supposed to pick it up yesterday i had to make a uh last-minute decision not to pick up the suit not to do the shotguns it was tailored and everything but i just didn't have the time i ran out of time so this young thief no new suit and there's a couple of other things i need to also have more important than a suit but i'm not going to mention it here live straight out yo for the water all right uh no that's okay right over there is fine thanks um as i was leaving home i read an email and because of this email i worked back upstairs reconnected the computer and printed it out we have a tremendous support to have by the way this doesn't look straight so maybe you straighten out the youtube a little bit better it's important to be exactly straight you might have to readjust the bottom of this like we have a tremendous cost of having uh rabbi yaakov schoenberg in al-shir he's a senior now shares a client has a tremendous hardest problem a long period he's become kakum he was there from day one i actually i should say from day two he claims he was actually listening by the door they were fine he's there from day one and he adds a tremendous amount to this year and yesterday i said that i tend to learn quietly and i was hoping that somebody could come up with uh you know that shouldn't be over what the gemara says of learning so he wrote me a very nice beautiful email i have to read some of it here with regard to learning out loud i can sympathize with you as i also tend to learn quietly however i think one can justify it somewhat okay season right away so i don't know if we could trust him 100 but it's beautiful what he says because the main discussion relates to the time when all the learning is by heart and repeating aloud helps memorize the text but here's the text for one's teaching does not memorize it it is lost when you don't have your teacher and that would be the zest nowadays that we have the kimono from in front of us memorizing does not have the same importance although hazard is still very important for the proper understanding of i believe that is the leading the concept of simon simon very strange as if someone's think that would be more difficult to memorize an unconnected sequence of strange words they don't need to memorize the series the actual phrase from the gemara so why is it memory he's asking why do we have simon in funny words and he says a beautiful idea i think the answer is that although it was forbidden to write down the text of the was permitted to write notes which were not the actual text it's very true and we had that before that people had their notebooks they wrote different things and things that they were going to forget but definitely see modern but the system of simon allows people to remind themselves of the text of a written semantic now that we have printed text in the gemara simulator no longer need it for that purpose so in our day and age you think are strange and those in that day when you weren't able to say the gimbal you weren't able to write down tomorrow simone made a lot of sense in south africa he was arrested in south africa for more than 50 years big loss in south africa of yeshiva college passed away unreal what's amazing is people might consider this a complicated or one of the most complicated soothings in ireland but with all the pictures and everything i think and we'll dumb it down a lot not because i'm dumbing it down it's because i'm dumb and i don't understand the depths of it so i think it'll be pretty simple omar have you namara well we're not there yet i'll let you know when we get there we're talking about it's going to be a studio of who is amazon is but really a very very simple concept simple ideas let me lower this okay maybe i'll i'll keep my i'll unmute it i'll make it much lower and if somebody actually has a question or something since it's a small island don't be shy you can ask questions today um yo please don't lean on the table because it shakes the camera thank you y'all y'all sit down over there please right over there it's good while helping him yeah i know it's good but over there is better um any city that has steep hills like the so again going against what we understand today yesterday we finished off we think salad is healthy the mars we think whole wheat is healthy we also think that a lot of exercise up and down hills is good for us tells us that a person who goes up and down hills dies at half of his life mason saw to die but he actually dies [Music] so you have a city that's square you square that now you don't need to square it out if you have a square you don't need a square value the more asks what's the finish it's already squared why would i think that you must square out a square how exactly you're going to square out something that's already a square says the gemara it's not squared to the directions of the world you put a compass and you have due north you have south you have east west your square is at an angle to though to those known lines that we have in the world so here's your north and south your this is north this is south your square is off it's off kilter you think that you have to spin it around and square it out like the blue line nice and final that's fine along with roy mildred islam you have to do so says the gemara now i added this these little guys here now if you don't know where north is you don't know where south is [Music] so you put it if you don't know where north is you just look at the stars now north is taurus it's uh ego calf course that looks a little bit similar you could always look at the maybe uh mute that yeah so you can always look north and you'll see where those stars are and you know where north it is south is across known as scorpion so you look up to the stars you see scorpion you know that's north that south if you always see how you matter the enemy there are bushels now if you don't know you're trying to make a city you don't know how to square it off to that to those coordinates mirabel kimin kufo oh so starting with the fun yo mask on your nose please thank you you you square it to so simple idea we know that the sun rises in the east and sets in the west however it's not a direct line from you it's not perfectly in the east and perfectly in the west sometimes the sun rises northeast sometimes it rises southeast so i took this picture from the mississippi black and white picture but for me this was the easiest one to explain this is north okay that's how in america we do the the map the top is north we're actually talking about the east where the sun rises this right over here this red circle is northeast right this is north of the sea so northeast the gemara says that sometimes the sun circles around the three walls of the of the earth goes around goes to the east to the south to the west and then sets over here so it makes this complete circle sort of and at night it hides and it goes over here from uh northwest to northeast that you don't see the sun here i put it in green i don't know if you can see it green arrows is what we see and the top is the night sometimes the sun this is in the summer a long day the sun rises and goes around but a very short day the shortest day of the year will rise all the way in the north west corner sorry the south east corner and travel just one direction of the of the oh what happened there hmm i guess i didn't print this okay i know what happened i tried to make i did on my but i forgot to uh to print it there's a line here just for this is the line that we're going for the north line i don't know how to create a north line to make a to make it square to the world you follow the sun where it rises and where it says you make a line here and a line here and that's your line that's your north line from here to here okay forget all this traveling you just want to see where it rises and where it sets that's one line the other line is we're tr where it rises in the winter and sets in the winter and that's the south the southern line the kids are if you don't know where the constellations are you don't know where taurus is you don't know where acura is in the sky just follow the sun depending where you are depending on the season of the year if you're in the summer so the sun takes this whole this whole trip and therefore you have a direct line from where it's where it rises to where it says yeah understood it's a simple concept [Music] where does it set that place up that gives you the northern wall concern on a short day the sun rises over here bishop and it only travels one side of the world that's your southern one the seasons in the middle of the year in between the summer and the winters nissan so the sun will come out over here instead of over here instead of over here either we're showing the two extremes northeast and north and southeast but sometimes it's in middle smack in the middle okay we'll take although uh 50 of the of the of the uni of the world that goes around and and it sits over here in mayra in the west that we are going to be reading this apostle tomorrow i believe when did they read pahella's in america so this is the [Music] afterwards we'll talk okay y'all afterwards all right [Music] means you could see him traveling you see him walking you see the sun when the soybeans and what and it disappears and it goes here you see it's sufficient it's dark on top it's dark you don't see the sun traveling the northern hemisphere that's hidden in sometimes you see the sun sometimes you don't see the sun as we explained before um i don't believe in any of these rules it never happened ever that the sun actually rose from the northeastern corner the shock of the caribbean and and set is that the word said right it rises okay and that it said over here in the in the north west corner it never happened sunset village mccarran is raucous and this never happened the bottom one where it came out from the southeast corner and set in the southwest corner that never happened either the shuttle camera so the kids are you don't have these lines that you're trying to create that's not going to work all right next so we survived part one of this now yo yo i know that you want to sleep very late but your mask needs to be on your nose and we have to be completely completely quiet let me show you okay okay yeah okay thanks um yeah y'all i took him home what maybe one 1 30. i'm finishing 1 15 1 30 in the morning he's here mama's a big big saddle so we're all we didn't discuss the question he was talking about other stuff maybe other things were more important i don't know sorry we will today on the way home he says today when i drive him home he'll discuss that question that's what he just said okay a boy said if a year was 364 days then we could divide 364 by a week by seven days and then we come up to 52 weeks exactly the problem is that a solar year has 365 days and six hours those those extra hours those 30 hours what caused that every so often you have to add a day in the month every few years five four years now we are talking about the seasons of the world the seasons so here's the seasons just not not to confuse anybody just a cool picture that we had while we learned if you divide the 365 days at the four equal parts because the year is three sixty five and six hours if you divide that by four what you come out with is 91 days seven and a half hours okay it's not we're not going to be discussing anything very deep and anything very difficult to understand 91 days seven and a half hours you have four coopers in this in the in the season right now as a side note just to explain we're learning the sun was created on wednesday evening because of this problem you have this extra 30 hours or this extra day and whatever it is yeah 30 hours in order to get to i don't know if i'm saying in the right place here let's go right there i'll say it in a second so 91 days i wanted to make it short but i ran out of time unfortunately 91 days seven and a half hours so if you just do very simple you look at a clock if the world or if the sun was created at 12 o'clock noon so it's not it's not good the sound okay then sev the next the next cycle is going to be seven and a half hours past that time right one day later if the sun was created on a wednesday wednesday night let's let's call it uh 6 p.m okay wednesday night 6 p.m then after the next koofa the next season which is 91 days seven and a half hours so you're gonna be off by one one day it's gonna be a thursday seven and a half hours seven and a half hours so it's gonna be 1 30 right you're at six o'clock plus six hours everybody knows six plus six is twelve but you're at seven and a half hours so you're gonna be at 1 30 a.m and then you do seven and a half hours plus 1 30 a.m is how much nine o'clock plus seven half hours four thirty okay so let's see in the gemara omar shmuel ain't cool fast nissan fellas now the sun was created in nissan nissan that's the beginning of everything the cell was created in isa so we're going to start with nissan ain't cool fast nissan fellas exactly very very simple exactly like our clock 12 6 12 6. okay can't get any simpler than that the first the first the first kufa so nissan always falls out at one of the four points at 12 p.m 12 a.m 6 a.m or 6 p.m that's it this is beautiful it's mama's smack in the middle for those hours all you need to do is add seven and a half hours for the next cycle for the next season to happen because the school fall is 91 days seven and a half hours so seven half hour forget the 91 days which comes out on a different day of the week will be instead of wednesday it will be thursday but thursday seven half hours later then 12 p.m which is 7 30 p.m not a big deal no no no don't let's not confuse that we have enough to be confused now says the gemara orbiter in the beginning of the when the sun comes up 6 am or at midnight oh sorry did i skip it 6 6 12 12. no therefore ain't cool so if you go seven and a half hours past six then the next koofa is going to be at 130. if you started at 12 this is mama's baby math even ponovitchers know this 12 plus seven and a half equals seven and a half it's gonna be 7 30. depending if you start at 12 a.m it's going to be 7 30 a.m if you start at 12 p.m 7 30 p.m okay now the next season is seven and a half hours on top of your 7 30 and 1 30 which equals weight conversation 3 o'clock orientation choice 9 o'clock depending on when you started in the evening or in the day veins now take the final season same exact thing you have to add seven and a half hours to three o'clock or seven half hours to nine o'clock fellas so it comes out to 4 30 and 10 30 banging by your baby yeah exactly first and the third on top of that or the other one is in the half hour great they nothing more explains the impaint couple of kufa elotion between a season and a season there's only 91 days vesheva choice or mexico seven half hours the ain't cuffing now we have what we're familiar with even today and the gemara was familiar with it we have mercury the moon saturn jupiter mars sun and venus those are the mazzales the masalas occur every hour we had it recently i had a whole chart how it could only fall out it's friday this that five every hour but every hour on the hour therefore it's possible because your your season falls out on the half hour because seven and a half hours you'll be smack in the middle of a muzzle it won't be in the beginning of the muzzle you'll fall out in the middle of mazel sorry no the most you could start into a different muzzle is a half hour there's no such thing that nissan the season of nissan will fall out on jupiter if it falls out in jupiter it's bad news shayna mischa bearishes or illinois they're going to be major storms that are going to break the trees davis fellas betzedik and if the season of tavis falls out in jupiter shayna may i bet right because every seven hours you have this oh and that's why before i forget to say so what's bhika sahama not to do with our city at all but once we're already here we might as well mention it we know that because happens every 28 years why because for the sun to come back to the exact spot where it was created on on wednesday evening at 6 00 pm let's say in kufas nissan will take 28 years to get to that spot because you are going to fall out on thursday and a couple of and then on friday until you get back to wednesday but even wednesday you're not going to be at 6 00 p.m you're gonna be at the wrong time so to get to wednesday at 6 00 p.m takes 28 years and when it reaches that exact point of mice and voracious so we all get together in the morning and we say birka sahama that's the sugi of kufaza but we touched upon it a little bit so now i just wanted to mention that so if you understand masolis and how things work and you know where we are in the with all the constellations and everything so you know that if tavis falls out and we know exactly when that happens it falls at on the hour of jupiter bad news for the farmers the abbeshes says is going to dry out all the seeds and that's only provided that the kiddush levana the the moon was born in the levan not our moon but in the mazel of moon right moon is one of the seven masalas so if the kids levana was born if it was if the moon was born in the mazel of moon or in the mazel of jupiter and tavis falls out in jupiter then you have a really bad combination 2037. okay so now we are turning april 8th 2037. how old are you going to be then we're turning to daf ahmed bayes sponsored by mark steinberg and anonymous he should have here we go so basically we are done with the kufiz people get very nervous oh kufu seasons i think it was not bad at all now we have a very very interesting suggest hammer abbas here i know there's a lot of pictures a lot of stuff simple stuff no time all questions afterwards here if you take if you take a a round city and you square it out okay so what's going on here the mark gives us a very simple way how to take your city and square it out so here in the city you have a circle so basically what you do is you add squares four squares one here one here one here one here once you have those squares in place you add squares to the corner one two three four the reason why you do that is because if you don't do it you'll end up with a completely different measurement if it's not completely square your city if it's a rectangle you want to add the 2000 amitrum on top two thousand at home in the bottom etc and then fill in the squares now if you were to take a measuring tape and measure from the corner and go on an angle the diagonal 2000 ammo rashi says you're going to lose out because you're going on an angle so that angle i drew a line here i gave myself the uh a lot of these pictures i added my own lines and stuff so you see this line over here that i added on top your line from the city to this blue line over here is going to be 1428 ammo you're really supposed to get 2 thousand amas so what the gemara is saying don't don't measure from this corner to this corner or 2000 hours from this corner to this red line right over here because what's that what that's going to do is give you this blue line over here which is only 14 28 you want to get to 2000 ammo so you're supposed to measure from this corner all the way to the tippy top but that gives you way more than you deserve that gives you two thousand eight hundred amaz okay so you got two thousand eight hundred dollars well there's more that you get for free there's a couple other there's another freebie because you have a circle right over here you're also getting the squaring out of the circle this this area right over here this green you see this green that equals 400 ammo so you're getting 400 for the green plus you're getting 800 for the blue if you're just to go 2000 ammo you get but right now you get 3200 ammo why because the angle the diagonal of a square is 1.4 of a square right in gemara math 1.4 so for every thousand ammo you get 400 free ammos but you have 2 000 ammos so that's 800 ammo free and the corner the actual corner right over here is 400 why because you're talking again 2000 ammo a square so this corner is 400 ammo until you use you first you square it out then you put another square on the side you're getting a total of 3200 ammo which is 1200 freebies you shouldn't get it so let's see inside i'm sure in math and all that stuff yeah i just don't know the name and ponovich they didn't teach me that here oyster is and you you go back and you square it out voiceovers and you fill in the corners and you make it a perfect square first you put squares here flag will explain and then four in the corner now i have perfect square um and when he measures don't measure the diagonal two thousand ammo the national map says you're not gonna have the entire corner you take a square and you place it in the diagonal and this square is exactly 2000 by 2000 ammo samala khan vibram island it comes out that in the green corners you get another four another 400 ammo mistakes and this guy gets the whole blue oh my my battery is running low that means that i'm not plugged in why i don't know it's not saying hold on why don't they have a battery that's the shiloh on the zoom done let me see real quickly sorry guys is it the right spot i have 23 minutes remaining it says it is it is it is in the right spot it's just maybe it's pulling yeah yeah well hopefully we finished it no idea are you sure that the the screen is not in the youtube the screen okay youtube is clear thank you all right fine why to get gangnam so we have 800 in the blue corner 400 in the green corner says 800 plus 400 is 1200 you gain extra 1200 ammo instead of 12 2000 army gain 3200 ammo if you're gonna count it from the circle till the the furthest point on a diagonal you get 3200 ammo omar abaya this idea they get four hundred plus eight hundred only happens says abaya in one case and we're gonna see that in fact there's another case this could happen when the city is exactly two thousand ammo by two thousand ammo okay oh my ruby elizabeth we're going to explain this that that statement that he said omar we actually just did we have two thousand by two thousand so you get four hundred plus eight on now says the gemara or revelation and this is going to take us to the bottom of the ahmad where we're going to stop a couple lines short three lines short of the bottom for today we know and we added just recently that the the city of the levium gets 2 000 ammo on all sides the first thousand amma depicted in a red in red line or yellow is fallow you can't plant anything there and this guy on the outside thousand ammo that's where you plant your vineyards your trees etc they did it they made it green i believe yeah i didn't do it i just i didn't like the yellow i didn't think the yellow was you were able to see so i added red to the yellow okay there's the inner and the outer circle but here's here's the trick and this is what throws us off nymta so if i first stop how much area is this thousand ammo compared to everything else the gemara says it's a quarter it's 25 percent minsa migration reveal this inner strip thousand ammo depicted by the red line to the city is twenty five percent the hashar and everything else 75 percent now i understand that the outer band is larger than the inner band it takes some more space but to say that's 25 percent that doesn't make sense how do we know the idea that's a thousand and thousand omarov the city should be it should be a buffer of a thousand nimsa migration so therefore the inner buffer is twenty-five percent of everything as the gemara reveals it's half well the gemara understands it's not half but the matter doesn't want to mess around with too many kashbinas and the corners and you're adding this and this let's do some easy math here it's similar to a half why are you telling me it's a 25 percent everybody knows it's not 25 so we have to get to 25 we have to understand a 25 percent how do you get to 25 oh my ravel i'll explain it to you but a person by the name of barado moshe hoya he used to be what do they call it in english a guy that takes uh measurements on the ground a surveyor here's a surveyor and he explained it to me he was not stamina if it's exactly a city that's 2000 by now very simple raboisei i like this picture the most this was from the mesifta from the isvahada not themselves if you have a city that's 2000 by 2000 i just took the liberty to make a blue line in the middle i'll explain to you soon your thumb is one box two backs four boxes and we fill up the corner with the red your thumb is the brown two thousand by two that we said to put a box here back here back here and then we fill in the corners now every box of 2000 ammo can be divided by four into four boxes so how many boxes do we have total one two three four five six seven eight eight times four equals 32 boxes right we have eight four reds four browns that's eight times each box we're gonna make it into a thousand by a thousand ammo each box is gonna be four boxes so we have a total of forty two boxes okay now next step shits how many boxes are in the trung well the chrome is the brown one two three four four times four sixteen boxes shits are sixteen chronos camera avion now the red also four boxes also 16. kama have you should say magno the truman variable the chronos now take off eight for the trom because how many brown boxes are next to the city eight two four six eight that's the trump how many boxes are touching how many corners are touching the city how many red backs are touching the city four so four plus eight how many brown boxes are touching the city two four six eight one two three four for a total of twelve oh so twelve how much is 12 in 32 it doesn't add up to a quarter adds up two maybe a third doubt money detrimental but the cronin is kind of a tracer you have 12. so now we find that the the this uh buffer is a quarter it's more than a third how can it be a quarter says the gemara i see our bod the muscle don't lean on the table yo so you have to add the four boxes from the center the four in the center make give us 36 boxes so 36 divided by four is not twelve twelve is again literally a third not a quarter akati tilta having we're not talking about a square b we're talking about a circle right the whole sugar was a circle you have to square out a circle uh oh i lost them yeah i lost zoom i think so what happened to the why okay no okay oh that's a good idea here just stand yeah i'm it's literally a minute unmute yourself uh you guys hear me we're just waiting a second rabbi is on youtube i'm sorry we're just trying to get the zoom zoom died on us the electric in america is not very good schmack i don't know why okay you give it a second until what's going on how come they don't hear you they hear you i hear you you guys hear me hello hold on we're going to get rabbit tourists get to do it no just stand stand back a little bit because you're not wearing a mask no stand over there that's okay no you can't leave it hold it for one minute just one minute so mama's one minute give it to joseph all right robert said we're not talking about a square we're talking about a circle and the gemara is telling us that the inner buffer for the levium is going to remain a circle we're not going to square it out if the levine have a circular city then the inner buffer this is going to be the inner buffer this blue line everything within the blue line is the inner buffer now because it's a circle forget there's no corners now we're not talking about corners anymore we're talking about just circle we're not we're not going to square it out we're talking about a circle we're not talking about a square b gula calmer a 2000 i'm a city that's a circle in other words the diameter is 2000 ammo but it's a circle but if it was a square how much larger would a square be than a circle we already did the math in a square but we're 25 percent less area on us on a circle than we are on a square and therefore kama maruba yasir ali eagle rivia you're 25 percent less now because the square is 25 more than a circle in gemara math dal reveal me nayu so take off 25 percent right because look the boy's side we said before that we have 12 squares we have 12 1 2 3 4 5 6 7 8 9 10 11 12. 12 squares fit into this blue two lines this area that surrounds the city that's twelve but if you need to take off twenty five percent and twelve you're left with nine so now we're dealing with nine squares why not because you don't have the corners you're in a circle you're this instead of this melo you're dealing with nine squares nine squares into 36 is how much 25 percent that's how we get to 25 percent that's why we're saying that the levy the levine's buffers 25 percent of them of of the total area you remain with nine vitisho mithlas veshito and nine out of thirty six riva javi that's how you get to a quarter rabbi said it wasn't that difficult they gave this daf a bad name even rav menachem wrote me a message he was trying to be funny he said ah i'm leaving the tufas and all that stuff to you i'm not going to give a shirt but it's simple stuff mom is simple our boys are here in chicago have a wonderful yanta of energy stroll have a good mayhed have a wonderful wonderful day [Music] a little bit a little bit
