What are some specialitys about the number systems ?

2000 BCE
What was the first number system ?
- Tallies were used (Stripes)
What was the problem with Talies ?
That we rapidly exceed the limits of perception
everything bigger then 4
Name the solutions on how to evolve the talies system:
Grouping of tallies and using Symbols instead !
What kind of grouping regading numbers did history come up with it ?
- -> 5 based units
- Why ? Because of perceptual limits which occurs after 5 and because we have 5 fingers - -> 10 based units
- -> 600 BCE Greek
- 24 units that is why we have 24 hour system - -> 500 BCE India
- place coding system - -> Sumerian: 60 Base units
- 60 min system
What is place coding regarding the india system ?
Place coding means that not only Forms of they symsbols matter but also placement!

3. The ability to talk to more than one person at a time - 2.76 times faster then grooming
4. Limit on 5 people to talk at the same time because of the distance between the speaker and listener
How do we identify group size ?
- Based on the growth of the neocortex
- And habbit specific (Umgebung)
- How much food and space is given
3: In generall they have a multitired social system-> in a big group there are many small groups(Key friends) which are good for protection

1. Paleozic era 540 to 250 million years ago - Born of fish plants insects amphibians and reptiles
2. Mesosize era 250 to 60 million years ago - Age of dinosaurs and beginning of mammals
3. Cenozic era: 66 million years ago - Age of only mammals (säugetire)
