@ -52,7 +52,7 @@ October 22 1925 has seen the invention of **[transistor](transistor.md)** by Jul
In 1931 [Kurt Gödel](kurt_godel.md), a genius mathematician and logician from Austria-Hunagry (nowadays Czech Republic), published revolutionary papers with his [incompleteness theorems](incompleteness.md) which proved that, simply put, mathematics has fundamental limits and "can't prove everything". This led to [Alan Turing](turing.md)'s publications in 1936 that nowadays stand as the **foundations of [computer science](compsci.md)** -- he introduced a theoretical computer called the **[Turing machine](turing_machine.md)** and with it he proved that computers, no matter how powerful, will never be able to "compute everything". Turing also predicted the importance of computers in the future and has created several [algorithms](algorithm.md) for future computers (such as a [chess](chess.md) playing program).
In 1938 [Konrad Zuse](konrad_zuse.md), a German engineer, constructed **[Z1](z1.md), the first working electric mechanical [digital](digital.md) partially programmable computer** in his parents' house. It weighted about a ton and wasn't very reliable, but brought huge innovation nevertheless. It was programmed with punched film tapes, however programming was limited, it was NOT [Turing complete](turing_complete.md) and there were only 8 instructions. Z1 ran on a frequency of 1 to 4 Hz and most operations took several clock cycles. It had a 16 word memory and worked with [floating point](float.md) numbers. The original computer was destroyed during the war but it was rebuilt and nowadays can be seen in a Berlin museum.

Zuse also soon created what's regarded as the **first [programming language](programming_language.md)**, [Plankalkul](plankalkul.md).
From 1939 to 1945 there was **[World War II](ww2.md)**.
