    ah
  • 00:00:13
    [Music]
  • 00:00:20
    my name is nasir ahmad
  • 00:00:24
    i'm originally from bangalore india
  • 00:00:27
    and i came to the united states
  • 00:00:31
    in 1961
  • 00:00:34
    to work on my master's degree
  • 00:00:37
    i had a bachelor's from india
  • 00:00:40
    at the university of new mexico when i
  • 00:00:42
    was finishing my
  • 00:00:45
    phd
  • 00:00:46
    i came up with this
  • 00:00:50
    discrete cosine transform
  • 00:00:52
    i had no idea
  • 00:00:54
    that it would
  • 00:00:56
    become
  • 00:00:57
    a major contribution
  • 00:00:59
    in those days
  • 00:01:00
    the digital technology was just starting
  • 00:01:04
    uh
  • 00:01:05
    to run a program
  • 00:01:08
    it was a big challenge it's not like
  • 00:01:11
    right now
  • 00:01:12
    you the student had to go
  • 00:01:14
    and put all of the program
  • 00:01:18
    in computer cards
  • 00:01:20
    and then you submitted that program
  • 00:01:23
    to the big ibm computer at the
  • 00:01:26
    university in that environment
  • 00:01:29
    is
  • 00:01:30
    when
  • 00:01:31
    this technology was proposed in 1974 and
  • 00:01:35
    this
  • 00:01:37
    little algorithm that we published
  • 00:01:39
    became
  • 00:01:40
    the most efficient way
  • 00:01:42
    of taking an image or a video
  • 00:01:46
    processing it in a way that it could be
  • 00:01:50
    compressed
  • 00:01:52
    and
  • 00:01:52
    transmitted to any place that you want
  • 00:01:56
    there were other people who published
  • 00:01:58
    but
  • 00:01:59
    it turned out that the discrete cosine
  • 00:02:01
    transform
  • 00:02:03
    survived to be the most widely used
  • 00:02:07
    and became a standard
  • 00:02:09
    and so
  • 00:02:12
    that that was a
  • 00:02:13
    key contribution
  • 00:02:15
    of mine
  • 00:02:19
    [Music]
  • 00:02:23
    i
  • 00:02:24
    decided to write a proposal
  • 00:02:26
    to the national science foundation
  • 00:02:29
    to ask for some money
  • 00:02:31
    to
  • 00:02:33
    work
  • 00:02:34
    on this
  • 00:02:35
    idea
  • 00:02:38
    and i thought it would get accepted
  • 00:02:41
    because it was a very novel idea
  • 00:02:44
    but to my surprise the reviewers
  • 00:02:47
    said that the idea was too simple
  • 00:02:51
    and so they rejected
  • 00:02:53
    the proposal
  • 00:02:56
    and so i told
  • 00:02:58
    kalitha that
  • 00:03:01
    i have this intuition that this thing is
  • 00:03:04
    the way to do it
  • 00:03:07
    but
  • 00:03:08
    can we
  • 00:03:09
    afford to
  • 00:03:11
    take the summer three months without any
  • 00:03:14
    salary
  • 00:03:15
    she said you know
  • 00:03:17
    we'll manage somehow
  • 00:03:19
    so
  • 00:03:20
    i kept working
  • 00:03:23
    on it
  • 00:03:24
    i had a
  • 00:03:25
    friend of mine in
  • 00:03:28
    the
  • 00:03:30
    university of southern california
  • 00:03:32
    when i sent him
  • 00:03:34
    the results that i got
  • 00:03:37
    he told me
  • 00:03:38
    publish these
  • 00:03:40
    results
  • 00:03:42
    right away
  • 00:03:43
    as a short paper in the computer
  • 00:03:45
    transactions
  • 00:03:47
    from then on
  • 00:03:49
    everyone started
  • 00:03:51
    referring to that short article
  • 00:03:54
    called the discrete cosine transform by
  • 00:03:57
    nasiraman
  • 00:04:00
    i was a reading author
  • 00:04:06
    the prestige was to publish not money
  • 00:04:09
    and those kind of things
  • 00:04:11
    that's the way
  • 00:04:12
    it used to be in
  • 00:04:15
    1974 you know we were all trained to be
  • 00:04:19
    pure
  • 00:04:20
    people who were academic people who
  • 00:04:23
    believed in publishing and the industry
  • 00:04:26
    was considered to be kind of separate
  • 00:04:29
    it would be nice if
  • 00:04:30
    but
  • 00:04:32
    if people
  • 00:04:34
    kind of see
  • 00:04:35
    [Music]
  • 00:04:36
    who developed it
  • 00:04:38
    but the reality is
  • 00:04:41
    life doesn't work like that to be very
  • 00:04:43
    honest
  • 00:04:46
    i couldn't predict
  • 00:04:48
    how fast
  • 00:04:50
    the technology would move
  • 00:04:53
    and just
  • 00:04:54
    amazed of how
  • 00:04:57
    all these technologies of facetime and
  • 00:05:00
    zoom and
  • 00:05:01
    they've come into place
  • 00:05:03
    and
  • 00:05:04
    that you don't like so
  • 00:05:06
    oh because you know
  • 00:05:07
    i it's not i don't like it i'm
  • 00:05:10
    uncomfortable that's
  • 00:05:12
    to me
  • 00:05:13
    just the fact that i see
  • 00:05:15
    it's being used so wildly
  • 00:05:19
    it makes me feel very happy
  • 00:05:23
    and
  • 00:05:24
    i was telling my wife is the most
  • 00:05:27
    wonderful gift
  • 00:05:29
    i got from
  • 00:05:31
    from life to
  • 00:05:33
    to be
  • 00:05:34
    recognized by ordinary people who can
  • 00:05:37
    use it and
  • 00:05:38
    i have to
  • 00:05:40
    emphasize that this wonderful
  • 00:05:44
    woman that i have next to me from
  • 00:05:45
    montires to kuman
  • 00:05:48
    helped me all through my career
  • 00:05:52
    she was always next to me
  • 00:05:54
    and a son
  • 00:05:56
    who loves his mother too
  • 00:05:58
    so proud of you see i'm gonna kiss you
  • 00:06:00
    in front of everybody

    from argentina who's computer
  • 00:06:21
    programming
  • 00:06:24
    anything good
  • 00:06:26
    it's about doring's development of his a
  • 00:06:28
    machine and how improving the
  • 00:06:30
    uncomputability of the unshidding's
  • 00:06:32
    problem by such a machine he showed the
  • 00:06:34
    fundamental limitations of mechanical
  • 00:06:36
    computation
  • 00:06:40
    i have no idea what you are talking
  • 00:06:42
    about
  • 00:06:46
    but i know i love hearing you talk
  • 00:06:50
    even i am peso
  • 00:06:52
    maybe totomar cafe she
  • 00:06:55
    used to tolerate my coming
  • 00:06:58
    late from the office and waiting for me
  • 00:07:00
    to eat with our son and and her
  • 00:07:03
    [Music]
  • 00:07:05
    hi
  • 00:07:08
    hi
  • 00:07:10
    what time does your watch day
  • 00:07:12
    um
  • 00:07:14
    9 53.
  • 00:07:16
    9 53. that's good
  • 00:07:19
    i was worried maybe all the clocks in
  • 00:07:20
    the house were fast
  • 00:07:22
    i didn't want to accuse you of being
  • 00:07:24
    three hours and 53 minutes late for no
  • 00:07:26
    reason
  • 00:07:29
    okay yes i one night
  • 00:07:31
    i asked you for one night to come home
  • 00:07:33
    at six to have dinner with your son
  • 00:07:37
    he was so excited for you to eat the
  • 00:07:38
    pizza i made you i wanted to make it
  • 00:07:41
    home what could you be doing in that
  • 00:07:42
    office that is so much more important
  • 00:07:44
    than us
  • 00:07:47
    i'm so close to something huge yes
  • 00:07:50
    no one has created an efficient
  • 00:07:52
    algorithm to compute the coronal law of
  • 00:07:54
    transform so i had the idea to approach
  • 00:07:56
    the problem by studying a cosine
  • 00:07:58
    transform
  • 00:08:04
    if i am going to forgive you
  • 00:08:07
    then i need to understand why what you
  • 00:08:09
    are doing matters so much
  • 00:08:29
    [Music]
  • 00:08:30
    then your mother wants a picture of mike
  • 00:08:32
    what do we do
  • 00:08:34
    we mail it to her right we mail it to
  • 00:08:37
    argentina she gets it a few weeks later
  • 00:08:40
    what if instead of waiting for the mail
  • 00:08:42
    she could see the photo on a computer
  • 00:08:45
    almost instantly
  • 00:08:47
    what do you mean
  • 00:08:49
    the military has created a network of
  • 00:08:51
    computers around the world they're all
  • 00:08:53
    connected
  • 00:08:54
    soon common people will have them
  • 00:08:56
    and if my team can optimize a form of
  • 00:08:59
    data compression
  • 00:09:02
    they'll be able to share images
  • 00:09:05
    so
  • 00:09:06
    you put a picture on a computer and
  • 00:09:09
    my mother across the world sees the same
  • 00:09:11
    picture yes and imagine if one day it
  • 00:09:13
    wasn't just a picture
  • 00:09:15
    imagine it was a movie
  • 00:09:17
    imagine you could talk to someone on a
  • 00:09:20
    screen
  • 00:09:21
    like a phone call
  • 00:09:23
    but with video
