Summary:

# Background material

- Fundamental (particle) Physics has no progress since the 1970s.

    - discovery of Higgs is confirmation of old Physics.

    - other predicted fundamental particles has never been discovered.
- Fine tuning problems

    - smallness of Higgs mass

    - smallness of the cosmological constants
- reductionism as Kenneth Wilson's concept of effective field theory (EFT)

    - separation of scales—UV (small scales)

        can be treated as a cut off of IR (large scales).
# Main message

The 2 fine tuning problems above are examples that are UV-sensitive, unlike other usual examples in EFT.

This is hint of physics that mixes UV and IR scale: example of black hole—higher energy -> larger event horizon.
