"THE PROFESSOR AND HIS BELOVED EQUATION" "My mother loved someone she couldn't marry and raised me on her own" "Uneducated and lonely, my mother became a housekeeper because it was the only option available for a person of her talents" "Your new clients may be a bit of a handful" "They've gone through 9 housekeepers in the past few years" "Though the youngest housekeeper at the agency, she already had 10 years experience" "My spirited mother pursued her profession with a fierce pride" "Excuse me" "I would like you to look after my brother-in-law" "Brother-in-law..." "Your husband's brother?" "No one lasts long" "Every time we get someone new, we have to start all over again" "It's such a bother" "I'm not asking for anything complicated" "Just feed and look after him from 11AM to 7PM" "Where is your brother?" "Don't come and go between the annex and the main house" "You work in my brother-in-law's house" "And it's up to you to solve any problems with him yourself" "You must promise me that" "I will" "Shall I meet your brother?" "There's no need" "Even if he meets you today, he won't remember you tomorrow" "What do you mean?" "In other words, frankly, his memory is impeded" "He hit his head in a traffic accident" "The same accident left me lame" "My brother's memories stop with the night we saw" "a Noh play by bonfire at Kohfukuji Temple, in the Spring of 1975" "It's been 10 years since the accident, but in his mind, we've always just seen the Noh play yesterday..." "In other words, it always just happened last night" "Ten years in a single day?" "He doesn't even realize that I age with each day's passing" "The way I was 10 years ago, is all he can see..." "All he will ever see" "In any event, his memory lasts 80 minutes" "That's exactly an hour and 20 minutes" "Over and over again" "So..." "I'll see you at 11am, Monday morning?" "Yes" "And so my mother came to work as a housekeeper in the professor's house" "The professor had been able to pursue his study of mathematics all the way to Cambridge University in England, thanks to his older brother's success in an inherited textile business which financed the much younger man's education" "After he earned his Ph.D., and found a position in mathematics research, his older brother passed away and his widow closed the factory, built apartments on the property moved out to the country, and lived on income from the apartments" "But their comfortable lives were shattered by the accident" "The professor lost his position, and became dependent on his sister-in-law's charity" "Hello!"

"Why, that's wonderful" "That's equivalent to the prime numbers up to one billion" "In any event, come in" "I'm busy working, so you're on your own" "Go ahead and suit yourself" "As of that day, my mother and the professor repeated this mathematical greeting every morning" "For the professor, whose memory spanned 80 minutes, my mother was always the new housekeeper" "For the professor, bringing up math was a communication strategy" "When he was confused about what to say, numbers could always take the place of words" "This character in the word "factorial"" "is the character for staircase" "The other character means multiply" "Whole numbers, refer to the integers which start 1, 2, 3, 4 and extend infinitely" "Multiply these and you get 24" "So 24 is the factorial of 4" "Now, who knows what the factorial of 5 is?" "Yes!" "120" "Correct" "How about the factorial of 7?" "5,040" "Correct" "You're fast" "This character in "prime number"" "means genuine" "Like something genuine without embellishment" "In other words, a number which is only divisible by 1 or itself" "For instance... 2, 3, 5, 7," "11, 13, 17, 19, 23, 29..." "These prime numbers are as infinite as the stars in the night sky" "No known rules govern them" "I am here, utterly self-sustaining" "In other words, just like all of you, each one is unique" "Utterly noble and unbending, these numbers remain aloof" ""Aloof"" "What the professor cherished most in this world, were these prime numbers" "Did he really love numbers?" "Sure, the object of his affections may have been eccentric, but not his love" "He cherished them, served them without compensation, respected them, always never straying from them for even a moment" "I'm sorry to bother you" "What would you like for lunch?"

"I made plenty" "April 7th" "Every day adds to the others" "We should be grateful spring has finally come" "Hello!" "Hello" "I'm your new housekeeper" "What's your shoe size?" "24, the factorial of 4" "That's wonderful" "What a noble number..." "Excuse me" "Yes" "Please send this to The Journal of Mathematics, at this address" "Sure, no problem" "By regular mail?" "Yes" "That'll be 170 yen" "Thank you" "I'm home" "Welcome home, thanks for your work" "Not at all" "Do you often submit your papers to magazines?" "Right..." "I sent my proof to The Journal of Mathematics, Vol. 37 today..." "That's good" "Oh, no!" "I should've sent it express Only First Place takes a cash prize" "No, there's no need to send it express" "It's important to arrive at the truth before anyone else, but it's more important that the proof be beautiful" "There are such things as beautiful or ugly proofs?" "Of course" "In a truly correct proof, air-tight and compelling reasoning coexists without contradiction, with supple logic" "Just as no one can prove why stars are beautiful, it's difficult to express the beauty of mathematics" "What's your birthday?" "February 20th" "What a charming number" "Take a look at this" "Back in college," "I won the President's award for my paper on Transcendental Number theory" "What a great honor" "No, that doesn't matter" "Can you read the number?" ""President's Award No. 284"" "Does that mean you're the 284th person to receive the honor?" "I suppose" "The question is 284 and 220" "This is no time to be washing dishes Come with me" "What do you think?" "Well, I..." "Both have 3 digits..." "How can I phrase this?" "At the meat counter at the supermarket, if there are two packets of ground beef, one 220 grams the other 284, they seem the same to me" "One quick glance and they look similar" "They're both in the 200 range and all the numbers are even" "That's a keen insight" "Intuition is important" "Grasp the numbers intuitively, from your heart" "You know what a divisor is?" "Yes, I think so I remember studying them..."

"I'm just using the same intuition you did" "Onto the next step" "Add it up" "Take your time" "I'm done" "Correct" "Will you behold, this beautiful chain of numbers" "Add all the divisors for 284 and you get 220" "Add all the divisors for 220 and you get 284" "They're amicable numbers" "Amicable numbers?" "Amicable Numbers" "Such pairs are very rare" "Even Fermat and Descartes only discovered one pair each" "They're numbers bound to each other by God's design" "God's design..." "Isn't it beautiful?" "Your birthday and the number engraved on my wristwatch are so perfectly intertwined" "The first person to discover amicable numbers was Pythagoras" "Pythagoras made his famous statement," ""Number is the within of all things"" "In the 6th century, B.C." "Have numbers been around that long?" "Of course Numbers existed before humans, no, even much, much longer" "They existed even before this world was born" "But humans invented numbers, right?" "Not at all." "No human being witnessed the birth of numbers" "They have always just been there, all along" "All humans can do is express with words, what numbers provide for us" "What do you think?" "Care to discover some more amicable numbers?" "By the way, the next smallest amicable numbers are 1184 and" "Four digits!" "No way!" "This pair..." "In 1866..." "Paganini, an Italian," "Nicolo Paganini, discovered this pair" "Can you believe it, at the time, Paganini was 16 years old" "In high school!"

"Yes" "How old is he?" "Ten years old" "Ten?" "Why, he's just a boy" "And where is your son now, what's he doing?" "Oh, I'm not sure" "Probably playing ball with his friends" ""Oh, I'm not sure"" "You should be more concerned" "It's going to get dark, soon" "Don't worry, he has a daily routine" "Routine?" "You routinely abandon your son to make hamburgers here?" "I don't abandon him" "It's just that this is my job..." "Who looks after him while you're away?" "Your husband comes home early?" "Oh..." "I get it" "He has a grandmother" "No, unfortunately, he has no father or grandmother" "My son and I live alone together" "Does your son wait for you alone?" "He waits for you with an empty stomach?" "While his mother cooks supper for a stranger..." "My supper..."

"Who will save him if a candy gets stuck in throat?" "It's terrifying to consider" "I can't bear it You must go home, now" "Right now, go home" "I won't be much longer I just have to cook the burgers" "Forget about that" "What if your son dies in a fire while you're cooking the burgers!" "Just let me..." "Now, listen" "Starting tomorrow, just bring your son with you" "Just have him come here, right after school" "You'll cook supper here and the three of us will eat together" "But that's..." "How dare a grown man stuff his face in front a hungry child" "But my contract..." "But if you don't cook him supper, until you get home from work, your son can't eat until after 8PM" "That's not right" "Don't underestimate me, assuming" "I'll have forgotten by tomorrow" "I'll have none of that I won't forget" "Her son 10 years old" "If you break our promise, I won't forgive you" "Hello!"

"There's +1 and -1, two of them" "The square root of -1" "The square root of -1..." "Is this +1 or -1?" "Impossible" "Why?" "Because the square roots of +1 and -1, are both +1" "Exactly" "All right, so the square root of -1, what exactly is it?" "There is no such number" "No, it's right here" "To answer this, the Italian mathematician, Rafael Bombelli..." "Rafael Bombelli, invented a new number, "i"" "This was in the 16th century, "i"" ""i" is an imaginary number" "Because it's a very modest number..." "It's written with the character for "candor,"" "and... the character for humility" "It never appears in the visible world, but it's always inside our hearts, using its short little arms to support its whole world" "What do you imagine from this "i"?"

"I like watching you cook" "Why do you have to... keep moving the meat around?" "The temperature varies from the center to the sides of the pan" "To cook things evenly, you have to shift them around" "I see" "They all share every spot, so that one can't monopolize the best spot" "What is..." "so fascinating?" "I'm just cooking" "Oh, it's so peaceful" "Root will be back, soon" "Root?" "He's my 10 year old son" "He has a flat head, so he's Root" "Oh, I see, you have a son?"
