More sanctions against Russia

UK ministers are preparing to unveil new sanctions against Russia, eight days after the poisoning of double agent Sergei Skripal that threatens to bring relations between the two countries to crisis point.

Boris Johnson, foreign secretary, and Gavin Williamson, defence secretary, who have emerged as the government’s most hawkish voices on Russia, are both in favour of financial and other sanctions against Moscow in response to Mr Skripal’s poisoning.

Russia really wants to win the World Cup.

Wow!

(Mr. Avenatti on Sunday pointed to a clause that said the agreement was “valid and binding” when “signed by all parties.”)

If this is true, Mr. Cohen blew it for the tune of $130K and a loss in a high-profile case.

Erase your whiteboards!

Last week I completely erased 3 out of 4 of my whiteboards and the empty boards immediately created an urge to develop new ideas. After playing (and struggling) with diagrams on my fresh boards for a couple of days, I succeeded in coming up with a functor that maps two of my favorite categories. Awodey's method of selectively erasing objects and arrows to experiment with forgetful functors really helped.

Cat 1
S<- SxH ->H
S -> H
H ->S
===========
Cat 2
1->2->3
1->3
2->3
3->2
===========
Functor mappings:

1 = F(SxH)
2 = F(S)
3 = F(H)

1->3 = F(SxH)->F(H)
1->2 = F(SxH)->F(S)
2->3 =F(S)->F(H)
3->2 =F(H)->F(S)

======
We can also consider the pair of S->H and H->S as a relationship on SxH; therefore, there must be a coequalizer. The relationship constraints outcomes (coequalizer) and it should be erased in a transition to a new category (1->2->3), which can be modeled by a forgetful functor.
