task 1 Flashcards
emergence of fire
first emerged during the time of homo Erectus
different uses of fire/consequences
- guarding against animal predators
- cooking food > better quality > growth of brain / less illnesses (less bacteria)
- as heating source > possibility of traveling to colder climates > cultural expansion
what are the fundamental problems with fire?
- problem of ignition:
- natural caused > is not always there when needed fire > what technique causes combustion?
- friction between two dry inflammable surfaces > raises point of contact to temperature at which combustion will occur
- problem of choice of fuel
- wood is most efficient producer of heat / some sorts are better than others
- breackthrough: charcoal
- problem of extension of the range of use
- application is largely confined to cooking by roasting
starting point of “science”
- discovery of pottery (5th millennium BC)
- discovery/development of glass (5.000 years ago)
- technology of metals (after pottery/most kinds: 19th century)
- writing and scientific record (6.000-300 BC)
- numbers/measurement (35.000-20.000 BC)
Cambrian explosion
- beginning of “real life”
- some 542 million years ago
- -> emergence of organic life forms
- -> start of photosynthesis
Cambrian explosion: further divisions
- Paleozoic era: 540-250 million
- Mesozoic era: 250-66 million
- Cenozoic era: 66 million to now
=> throughout this time: intelligence wasn’t necessary for survival
Neolithic revolution
- around 10.000 BC
- transition from nomadic HUNTER-GATHERER -> FARMING & SETTLEMENT
- greater complexity of SOCIAL INTERACTIONS
- further impetus for THOUGHT & LANGUAGE DEVELOPMENT
- sedentary farming communities changed human interactions:
- -> from COOPERATION & SHARING > PROTECTION of goods & increased level of CONFLICT
preliterate civilisation: 3 characteristics
-> Lindberg
- KNOW-HOW
- knowledge is confined to “know-how” WITHOUT theoretical understanding of underlying principles - FLUIDITY OF KNOWLEDGE
- historical knowledge is limited to two generations
- function of oral tradition is transmission of practical skills - ANIMISM
- collection of myths and stories about beginning of universe / life / natural phenomena / etc.
- -> based on animism
=> scientific thinking cannot occur without written records
animism
- explanation of workings of the world and the universe by means of spirits with human-like characteristics
- distinction between “primitive people” and “scientific thinking”
protowriting
- emerged at around 6.000-300 BC in China / Egypt & Sumer / America
- represents entities without linguistic information linking them
- writing systems were a combination of pictograms and phonograms
- led to alphabetic writing system
- -> became logographic rather than pictographic
pictograms & phonograms
pictogram:
information conveying sign that consists of a picture resembling the object it represents
phonogram:
a sign that represents a sound or a syllable of spoken language
first alphabet ?????????
=> written records as basis of comulative nature of science
–> however: Socrates thought that availability of books made students lazy and discouraged them from properly studying
scholastic method
- particularly in the Middle ages
- students were taught to read and understand texts exactly as they were
- its abandonment by the Protestant churches was one of the reasons why science took such a high flight
scriptio continua
- in 8th century
- writers start to put spaces between the words
- -> this quality of texts made silent reading possible
numbers
- 35.000-20.000 BC: earliest evidence of counting
- quite early in evolution of human they could make distinctions up to three
- -> subitising
- all Indo-European languages share same roots for umbers 1 to 10
- -> split around 2.000 BC
