3 years from when russia invaded Ukraine. When the USA told the leader of the free world President Zelensky to leave, and he replied "I don't need a ride. I need ammunition".
This is the first slide of every talk I gave in the last 3 years. This thread is about (quantum) science in Ukraine. 🧵

Winter is the most challenging time in Ukraine: Russian attacks damage power supply, leaving vulnerable populations in the dark, cold and vulnerable.

Would the new Research Misconduct policy drafted by the University of Pittsburgh stop the next Pruittgate? Absolutely not.
But will it allow the university to investigate the next problem in a transparent and unbiased way? Also not.

One way to get accepted to Nature Physics is to get rejected from Nature and Science. And one way to get rejected from Nature and Science is for scientific reasons. This is how bad papers make it into Nature Physics.

if I were springer-nature I could maintain financial solvency by simply collecting APCs and publishing papers that show how all the other stuff they reported is wrong. And I would not even publish any new stuff. Free advice.
It's a letter, highlighting a fundamental flaw in a paper that they recently published. How much do you wanna bet that they don't accept it? 🙄

I say 'We just published our paper on arXiv'.
'Preprint' is a meaningless term now. First, we do not print. Second, it is not 'pre' - it is the event. This is when we published the paper, is when we published it on arxiv.
We need to retire the term 'preprint'.

Preprints are read, shared, and cited, yet still dismissed as incomplete until blessed by a publisher. I argue that the true measure of scholarship lies in open exchange, not in the industry’s gatekeeping of what counts as published.
