Title: THE SCIENCE IN THE LEFT HAND OF DARKNESS


1
THE SCIENCE IN THE LEFT HAND OF DARKNESS
  • SONJA DEŽMAN

2
SCIENCES
  • NATURAL SCIENCES
  • Astronomy
  • Physics
  • Mathematics
  • Biology
  • Geology
  • Meteorology
  • SOCIAL SCIENCES
  • Geography
  • History
  • Linguistics
  • Cultural studies
  • Psychology

3
MAYOR IMPORTANCE
  • ASTRONOMY life on other planets, planet Winter,
    space travel
  • PHYSYCS time jumps, twin paradox
  • BIOLOGY androgyny, hibernation

4
LIFE ON OTHER PLANETS
  • MARS
  • OUR SOLAR SYSTEM (Sun, 9 planets, Moons)
  • MILKY WAY
  • (200 400 billion stars)
  • THE OBSERVABLE UNIVERSE
  • (more than a 100 billion galaxies)

5
ALPHA CENTAURI
  • Closest solar system
  • (4.35 light years)
  • Alpha Centauri A , Alpha Centauri B, Alpha
    Centauri C Proxima
  • A 5 tests, B 4 tests, C 0 tests

6
TESTS FOR LIFE ON OTHER PLANETS
  • The stars stability
  • The spectral type of the star (G-type)
  • Stable conditions
  • Stars age
  • Enough heavy elements (carbon, nitrogen, oxygen,
    iron)
  • Planets!!!

7
SPACE TRAVEL AND HIBERNATION
  • Earth ? Alpha Centauri 18000 years (4200 years)

8
HIBERNATION
  • Hibernation used by animals
  • (bats, squirrels, hedgehogs,
  • bears, etc. saves energy, lowers
  • body temp., slows down breathing
  • and metabolism)
  • Coincidental hibernation (snow, cold water,
    freezing temp.)
  • Real hibernation (air filled with hydrogen
    sulphide vs cryonics)

9
TWIN PARADOX, TIME JUMPS
10
PLANET WINTER vs PLANET EARTH
  • EARTH
  • Period of rotation 23.9345 hours
  • 1 year 365.25 days
  • 1 month 30/31 days
  • 12 months
  • Adjustement in 4 years
  • 1 day 24 hours
  • Moon the same face
  • WINTER/GETHEN
  • Period of rotation 23.08 hours
  • 1 year 364 days
  • 1 month 26 days
  • 14 months
  • Adjustement in 200 years
  • 1 day 10 hours
  • Moon the same face

11
GETHENIANS
  • sexual cycle 26 28 days
  • 21 22 days sexualy inactive, 18th day hormonal
    changes, 22nd or 23rd day kemmer
  • 1st phase of kemmer androgyns, 2nd phase of
    kemmer changing into man or woman, 3rd phase of
    kemmer 2-5 days
  • pregnancy 8.4 months, lactation period 6-8 months

12
ANDROGYNY / HERMAPHRODISM
  • THREE BILOGICAL PHENOMENA

13
MALE and FEMALE
  • HAMLET fish (both sexes a pair takes turns in
    mating)
  • EARTHWORMS (a single sex at a time protective
    mechanisms against self fertilization)
  • BANANA SLUGS (self fertilization is often
    practiced)

14
MALE?FEMALE, FEMALE?MALE
  • CLOWNFISH (harems, male ? female)
  • WRASSES reef fish (females ? grow up ? males OR
    males and females ? supermale)

15
ABNORMALITIES IN PRIMATES
  • the primate is either genetically male or female,
    but has external organs resembling those of the
    opposite sex
  • 1 of mammals
  • humans altered shortly after birth
  • neither set of organs is functional

16
  • LIGHT IS THE LEFT HAND OF DARKNESS
  • AND DARKNESS THE RIGHT HAND OF LIGHT.
  • TWO ARE ONE, LIFE AND DEATH, LYING
  • TOGETHER LIKE LOVERS IN KEMMER,
  • LIKE HANDS JOINED TOGETHER,
  • LIKE THE END AND THE WAY.
