Quod erat demonstrandum

Cos(Pi n x)…

Quod erat demonstrandum.

Fine-tuning the Fourier theory is a modern research topic.

I found another basis for the function space,

one with an increasingly narrower body.

Those interested are welcome in my office.

This basis holds various uses.

You can compress an audio recording or a film,

remove white noise,

recognise an image or a voice.

You read a text

and the computer translates it into text format.

You can write a program that can recognise,

out of all possible sounds, that of a Rubik's cube.

A Party member must do everything

for the triumph of socialism and communism,

serve the interests of the people, always concern himself with…"

Sometimes, in life, one does what one has to do…

You need to attend conferences and present your ideas

about the function bases.

This is the secret of evolution: communication.

In principle, your theorem is quite interesting.

-And the proof is correct. -Then why am I not published?

I'll never be able to finish my PhD. I'm 35!

How much longer should I wait?

Unless you do what's right, you'll never finish it,

and that would be a pity.

When you appointed me as your assistant, it didn't matter

I wasn't a Party member.

Take it with you, read it and learn it.

It shouldn't take you more than 2 days.

-Hello… -Come in.

Computer programming can make design work more efficient,

which increases the building rhythm.

Taking into account the Party's decision

regarding the 1986-1990 5-year plan,

the solution to the tenement problem

is to assign 14 square metres to each inhabitant.

Thank you.

Let's go out for a cigarette.

Don't go yet, please.

I see you're up to date with the Party debates

and the 5-year plan, but I just don't get you…

You acknowledge the achievements of Socialism,

but you still haven't withdrawn your papers.

I thought we talked about this…

You told me you're confused and don't know what to do

I asked you to withdraw your papers.

Here's the sugar.

Put yourself in my shoes, comrade Brediceanu?

Would you stay here and raise the child by yourself?

Elena, don't be disrespectful. You know very well what I mean.

The Party directives are very clear.

When people are called abroad, they must understand

that they can have the same things here.

If you really want to, you can build a new family, here.

You have plenty to choose from…

But these are two completely different things:

what I can do and what I must do. Right?

-Do you have kids? -Let's not mix things up.

You know very well what I mean.

Look… This pencil, for example…

It can write, but it can also erase.

Thinks are very simple. Think about it.

We need valuable people like you,

but we can't go on erasing stuff.

You know, things aren't peachy in France, either!

Is that all?

-What did Brediceanu want? -As if you don't know already…

-What he usually wants… -Screw him!

-There's nothing he can do to us! -He can throw us out…

He can't! He doesn't control you.

But it won't be easy for me with only my father's pension.

-Should I bring you more of these? -I have some left. Don't worry.

-And Ducu? How is he? -Ducu's fine.

One of his cousins promised to help him find a job.

But you know what she told him after?

Every man for himself, that's the way of the West."

-Is it any different here? -Come on, Angela!

As for Brediceanu, sweet-talk him, like I do.

It's from our embassy in Washington.

Sorin Pârvu… Was he checked?

-Is it a real name? -That's why it was sent to us.

He's a lecturer at the Faculty of Mathematics.

He's never received approval to publish abroad,

and we have to see if this paper has any scientific value.

It's easy. The dean works for us.

We also have to find out how the paper reached America.

Understood.

Did you hear they promoted Stămătoiu to general.

-So? -We used to be in the same class.

-We have the same age. -That doesn't mean anything!

I'm just a lieutenant-colonel.

How much longer am I supposed to wait? I'm 45!

I have enough references and solved cases…

I have a good file and a network of informants…

And yet, I'm stuck!

It's the diploma, Alecu! You need a diploma in your file.

You have to attend the Party school.

-It's because of my divorce. -No… In theory, no.

But if I wasn't divorced, it would be easier, right?

Knot 8 for carp fishing! Do you know how to make it?

See? That's the problem!

Get away from those files from time to time.

You think that hiding behind Deleanu's skirt

will get you anywhere?

He belongs to a different generation.

He's more…

Come fishing with us!

Look… every Sunday, during summer,

I take the General to the lake.

We're river fishing, now. Predatory fish.

I'll put you on the list for the winter school session.

Relax! I was on the list but someone took me off it.

Who? Deleanu?!

No way! He has no reason to… It must be the divorce!

You're naive… If you get promoted,

who's going to solve his cases, huh?

I've put you on the list and I'll inform the General.

-Do you have any open case? -I do!

Close it, then… And think about it.

I don't want to teach you what to do, I'm just saying…

Come fishing!

-Good afternoon! -Hello, Elena!

-Good day, ma'am! -Hello…

Oh, it's just a thread. That'll be 1 leu.

-You want it fixed now? -Yes…

-How's David? -He's fine. He's studying Latin.

-I'd better come back later. -Okay.

Queues… Fights… Scandal… But I managed to get some.

I waited in line two times: for salami,

and for the groceries. I got some milk, too…

I saw bananas, but I didn't get any.

I didn't get any, but I saw them…

Bananas in October?! They're spoiling us!

David finished his French lesson,

he ate, and now he's doing his homework.

I did the laundry and cooked potatoes.

-The coffee maker is broken… -I know, you told me.

-Let's throw it out. -Nonsense! It's made in France.

I'll clean it with sodium and make it brand new.

I could have eaten these with mussels.

That can Ducu sent us… Moules aux champignons.

Mussels with mushrooms? I'm not eating that!

-Give it to someone. -Come on, Dad!

Did you put water in that pot?

I did…

Thank you for dinner!

Why did he have to make a fuss?

He knew I'd asked to move to France.

-He's just vituperating. -He's what?

These Party guys… It's their job to mess with you. Don't worry…

All is for the best.

You'll see… You'll get to France in no time.

Ubi bene, ibi patria!

And, above all, it will be good for the kid.

Yes, Dad, I know. It's mainly for the kid.

But all this insecurity… Why did he have to leave?

Weren't we okay here?! Now I have to change everything.

I'm not that young anymore!

-What are you doing there, Dad? -It's for the jars…

-What did you do today? -I took the groceries ration…

I've told you not to queue up anymore. I'll do it!

Don't worry! Time went by pretty fast.

I've chatted with our neighbour…

She bought a colour TV.

If you want to, I'll get on the waiting list.

But black & white or colour, it's all the same…

-All you need is a bit of imagination! -Always joking!

And what's this? Another one of your jokes?

You went through my stuff again!

-I've asked you not to… -I didn't go through your stuff!

I was cleaning the room…

Why didn't you tell me you've published in America?

So I can brag to the neighbour…

Who helped you publish this?

Do you really want to ruin you career and your life?!

They can't do anything to me! It's not the 50s anymore…

I'm not talking against the Party, am I?

I'm not cursing them or spitting at them!

You don't know anything about the 50s!

As if now were better… Afraid of your own shadow!

You can't trust anyone. They could take away our home.

Is this what you want?

I'm telling you, everything will be alright…

We're selling this one, and giving this one to our neighbour.

Who opened this pack?! David!

Are you deaf now?

Go to your room! Don't you have homework to do?

-Maybe we should sell it. -Right!

After all, no one's used it since Ducu left.

But you need the documents from the Militia.

-What are you studying there? -Math!

-Fractions? -Fractions.

Who do you think you're fooling?!

You're reading a bit too much.

Finish your homework, and go to bed, okay?

Hello, I'm Alexandru Spiridon. I've phoned you earlier…

Hello… Please, come in…

We're decorating…
