Maybe that's why they showed a flying pirate scenario. Imagine every object sitting on the same planet (object). Suddenly, everything interacts with everything. You can't know if the object is a bee gently landing on a flower, or

What about Japan? They tried to buy economic growth (dubbed Abenomics) and failed horribly. The economy is worse and government debt is higher than ever. Models that can't explain some weird edge cases are ok. But what happened in Japa

You are fighting a mathematically pure interpretation of black boxes that are making no assumptions at all. Your observations are correct. But nobody actually interprets the term "black box" the way you deem wrong. Taken from here

Energy from renewals is cheap and plenty. Generation is not the problem. Storage is. In Germany, there is excess energy in the system when the sun is shining/wind blowing, even with many conventional plants shut off. It goes to the poi

Yes, there is such a thing. There exist many more techniques than trivially assuming some "template" function and fitting the function parameters against the data. Have a look at nonparametric modelling techniques. For example ker

Since the introduction of the Euro, many EU states got money a lot cheaper than they should have, due to their association to the stronger neighbouring economies. That started a completely irresponsible spending frenzy that was well-receive
