P roton I mprovement P lan-II (PIP-II) is Fermilab's plan for providing powerful, high-intensity proton beams to the laboratory's experiments. The increased beam power will position Fermilab as the leading laboratory in the world for accelerator-based neutrino experiments.
The flag of Sweden is the national flag of the Kingdom of Sweden. It consists of a yellow or gold Nordic Cross (i.e. an asymmetrical horizontal cross, with the crossbar closer to the hoist than the fly, with the cross extending to the edge of the flag) on a field of blue.
The development was going to a united Scandinavia with one language and one culture. The Swedish rebells wanted to build a Swedish nation state (kind of anacronism but it is a good explanation). One part of the nationbuilding was to create a Swedish nation flag. There was just one known shape for a nation flag: Dannebrogen. The nation builders had just to choose colours. The Swedish colours were already there: Yellow and Blue, the colours of the Swedish coat of arms: three golden crowns on a blue background.
