BORING

PRESENTATION

FOR 2 REASONS.

BORING

PRESENTATION

FOR 2 REASONS. I GUESS SO.

AN

EXCELLENT

#1

too many equations. text. garbage.

BORING

BECAUSE

storytelling.

EXCELLENT

BECAUSE

#2

random blah blah. bad storytelling.

BORING

BECAUSE

to be bored.

MY BIO

INDEPENDENT

FILMMAKER

WRITER. ALSO.

I LOVE IDEAS,

EXPERIMENT &

LIMITATION

& ENJOY

WORKING WITH

RUPANTOR

MICROCINEMA TEAM

BUT ONCE

I STUDIED

MATHEMATICS

UNDERGRAD. BORING.

I HAD TO MAKE

PRESENTATION WITH

MATHEMATICS

THAT’S WHY BORING

AND THIS

PRESENTATION DEALS

SCATTERING THEORY

ALSO SCARING

SO LET’S EXPLORE

INVERSE SCATTERING &

SCATTERING BLAH BLAH

YOU ARE WARNED.

GOOGLE. PLEASE.

I would do the same thing.

ALWAYS.

SCATTERING. EXAMPLE.

Wave scattering

Sunlight scattered by rain drops

To make your

presentation boring,

never insert photo.

like me.

TIPS #1

To make your

presentation boring,

never insert photo.

use clipart.

TIPS #1

Direct Scattering Problem

use

symbol. jargon. whenever you can.

Inverse Scattering Problem

Just the inverse

and vice versa.

INPUT BECOMES OUTPUT.

you will be.

STEPHEN HAWKING SAID,

IN BRIEF HISTORY OF TIME

every equation

helps to lose the readers by half.

SOMETHING LIKE THIS.

how many equations

I have used here?

HA HA HA…

you there?

OOPS.

anybody?

HELLO.

forget everything I said.

SORRY.
