In
this
set
of
video
lectures
given
in
1979
by
Nobel
prize-winning
physicist
Richard
Feynman,
presents
not
only
a
lesson
in
basic
physics
but
also
a
deep
insight
into
the
approach
of
the
17th
century
physicist,
Isaac
Newton.
The
first
lecture,
Photons
-
Corpuscles
of
Light,
is
an
introduction
to
photons
and
their
properties
as
well
as
to
the
theory
of
quantum
electrodynamics
and
the
calculation
of

In
1985
an
experiment,
designed
to
unravel
the
carbon
chemistry
in
red
giant
stars,
revealed
the
existence
of
C60
or
buckminsterfullerene
(a
special
form
of
carbon,
known
also
as
bucky
balls).
This
video
lecture
describes
the
story
of
the
discovery
of
this
molecule
and
the
way
its
symmetry
relates
to
the
natural
and
physical
world.
This
elegant
hollow
cage-like
molecule
which
has
the
same
shape
as

In
this
lecture,
a
researcher
with
the
Ocean
Mammal
Institute
discusses
her
work
with
humpback
whales
in
Hawaii,
where
she
studies
their
use
of
sound
to
communicate.
She
shares
video
and
sound
recordings
to
illustrate
her
work
and
presents
research
on
the
effect
of
thrill
craft
and
engine
noise
on
the
whales.
The
researcher
also
presents
the
broader
implications
of
her
work
regarding
impacts
of

In
modern
organisms,
there
is
a
division
of
labor
between
two
kinds
of
molecule:
DNA,
which
stores
and
transmits
genetic
information,
and
proteins,
which
do
all
the
work.
They
are
connected
by
the
genetic
code,
whereby
DNA
specifies
what
kinds
of
proteins
can
be
made.
This
process
of
translation
is
well
understood,
but
it
is
far
too
complicated
to
have
arisen
by
chance
in
the
primitive
oceans.

In
this
lecture,
a
physics
professor
describes
wormholes
in
space
and
other
ideas
that
might
allow
travel
into
the
past
or
future,
based
on
special
and
general
relativity
and
quantum
physics.
The
physicist
explains
how
oscillating
particle
worldlines
can
be
due
to
a
force
or
curved
spacetime;
how
time
travel
can
be
possible
with
closed
timelike
loops
in
spacetime;
and
what
the
main
time

This
video
lecture
explores
the
effects
of
climate
change
on
the
Ross
Ice
Shelf
in
Antarctica.
Slides
depict
how
a
large
iceberg
fell
off
the
Ross
Ice
Shelf
in
March
2000.
The
lecturer
describes
his
expedition
to
the
ice
shelf
shortly
after
this
event.
He
describes
dives
conducted
to
observe
the
underwater
ecosystems
containing
krill
and
jellyfish,
and
the
ocean
currents
around
the
icebergs.

In
this
lecture,
an
oceanographer
describes
studies
that
he
and
a
team
of
scientists
conducted
exploring
historical
human-caused
changes
to
various
marine
ecosystems.
The
historical
analysis
helps
us
understand
ecosystems
and
how
to
fix
them.
A
highlight
of
the
talk
is
the
presentation
of
a
new
short
film
called
Rediagnosing
the
Oceans,
cowritten
by
the
speaker.
The
speaker
explains
how
he

This
guided
tour
of
the
dinosaur
known
as
Dilophosaurus
is
narrated
by
the
discoverer
of
Dilophosaurus,
Sam
Welles,
formerly
a
professor
at
the
University
of
California
Museum
of
Paleontology
(UCMP).
Links
lead
to
Dr.
Wells'
description
of
the
discovery,
as
well
as
the
morphology
and
habits
of
the
creature.
He
also
compares
and
contrasts
the
real
animal
with
the
one

The
Arctic
is
changing
in
dramatic
and
disturbing
ways
with
giant
lakes
replacing
what
used
to
be
ice
fields.

data
showing
ice
over
the
Arctic
Ocean
retreating
over
recent
decades;
military
submarine
data

video
lecture,
Helen
Sharman,
the
first
British
astronaut,
gives
an
account
of
her

the
way
the
Third
Law
of
Newton
and
convection
apply
to
rockets,
space
flight,
weightlessness
and
survival.
Sharman
