“When people ask me if a god created the universe, I tell them that the question itself makes no sense. Time didn’t exist before the big bang, so there is no time for god to make the universe in. It’s like asking directions to the edge of the earth; The Earth is a sphere; it doesn’t have an edge; so looking for it is a futile exercise. We are each free to believe what we want, and it’s my view that the simplest explanation is; there is no god. No one created our universe,and no one directs our fate. This leads me to a profound realization; There is probably no heaven, and no afterlife either. We have this one life to appreciate the grand design of the universe, and for that I am extremely grateful.”
― Stephen Hawking
One of my favorite #mathematics papers is a paper by Milnor "On manifolds homeomorphic to the 7-sphere" from 1956.
It's only 7 pages long (8 with bibliography). Milnor showed that there exists a smooth 7-manifold homeomorphic but not diffeomorphic to the 7-sphere. The proof is absolutely beautiful and has influenced much of the development of high dimensional topology to this day.
People who think they know everything are a great annoyance to those of us who do.
“Instead of pouring more money into militarized forces that brutalize, terrorize, and even murder, we should fund libraries, after-school programs, good jobs, and other investments proven to keep us safe.”
In 2013, before giving some math lectures in Lanzhou, Lisa and I visited Dunhuang and the eastern fringes of the Taklamakan Desert. In preparation for this trip I spent some time reading about the area. I greatly enjoyed Hopkirk's Foreign Devils on the Silk Road. It's an old, romantic book. Here is a passage from it, and some pictures from my trip.

He believes that Putin may try to launch a large-scale attack from the north, south and east, as happened on February 24, 2022, timing it on the anniversary of the war. #Ukraine #News #War #Russia
Anti-vaccine misinformation makes it through peer review.
Shocking that a paper by a known anti-vaccine
activist, based on a badly designed self-report survey, made it through peer review to publication. Even as a qualitative researcher I can spot the design flaw in asking people "do you know anyone who died of the jab?" and then treating that as a fact to calculate the number of deaths caused by the vaccine.
It should be withdrawn.

A few weeks ago @heidilifeldman wrote about the German Nazis coming to power:
“Today’s American Nazis are gaining the same kind of power the German Nazis did in the 1930s.”
And the #media parallels are also strong. The publisher of the Daily Mail in the 1930s was an explicit fascist, a member of a British fascist party. There is strong similarity to Murdoch and Wilks and Koch and Singer.
Political fascism hasn’t changed much—billionaires to dangerous lickspittles. https://www.notesfromcalicomanor.com/2023/01/07/todays-american-nazis-are-gaining-the-same-kind-of-power-the-german-nazis-did-in-the-1930s/
