Ich bin wirklich sehr für moralische Regeln. Ich fand "the witch is dead" nach Thatchers Tod geschmacklos. Ich habe mich sogar beim Jubel über Bin Ladens Ermordung geärgert. Aber wenn nach Trumps Tod Menschen weltweit auf der Straße feiern, dann mache ich mir auch eine richtig gute Flasche auf.

For reasons I currently have to create a presentation with PowerPoint - and I just learned that PowerPoint cannot animate tables? E.g., have it appear row by row? Apparently the officially recommended way is to turn the table into a vector graphic, un-group it and then animate the parts ... WTF?!

Did you know? The city of Passau sometimes has these weird red stripes alongside roads. These are there to indicate where you can dump excess snow 🙂👍 In the summer, you may, of course, also use them for parking!

A photo of a street crossing for cyclists and pedestrians. On one side of the road there is also a red stripe indicating a cycling lane. While the road itself is completely snow free, there is still snow on the red stripes and blocking several parts of the crossing.

In conclusion, we should negotiate! But Putin won't be won over through superior argument or an appeal to higher morals. This is about power. Ukrainians will have to make painful concessions either way, but there's a difference between that and outright surrender

Very sad that I felt I had no choice but to resign from The Infinite Monkey Cage - a victory for the transphobes and other bigots - I did it because so much of the media has chosen to believe the kind and empathetic people are a fiction - they are real and so often unrepresented.

This is the saddest day of my professional life.
Today is not only the final recording of the latest series of The Infinite Monkey Cage, it is my last ever Monkey Cage.
I never thought that I would have to leave the show. I always imagined going on until | dropped dead under the studio lights due to a brain aneurysm caused by my final attempt to understand notions of quantum gravity or the shock of being told about fly maggot infestations in the sacks of macaque monkeys.
I resigned in September, after sixteen years of dedication to the show,
A show that I named and helped develop over all those years.
Unfortunately, my opinions outside the BBC have been considered problematic for sometime, whether it has been voicing support for the trans community, criticism of Donald Trump, numerous other outlandish opinions, including once gently criticising Stephen Fry.
These things were considered to conflict with being a freelance BBC science presenter

In a recent meeting where BBC Studio executives again voiced problems with me, I realised my choices.
Obedience and being quieter to remain making Monkey Cage, or 'Resign and have the freedom to speak out against what I believe are injustices'.
•
I chose the latter.
It broke my heart.
I love this show and I love the audience, and it is because of the audience in particular, that this decision was so difficult to make.
I kept thinking about all the extremist voices promoting hate and division. They are being given so many platforms, while voices that represent kindness, open mindedness, empathy seem to be scarcer and scarcer.
I felt I couldn't pamper myself with the luxury of silence.
One of my many privileges is that I am able to resign and I can speak out even if it is to the detriment of my career.

I have thought a lot about my heroes, Sinead O Connor, James Baldwin, Audre Lorde, and so many more.
I think of Sinead's words, "the job of an artist is to be themselves at any cost".
James Baldwin said prejudice was really just a word for cowardice.
Audre Lorde, viewing her life, wrote that her only regrets were her silences.
I think of my father as I resign, he brought me up to believe in fairness , justice and kindness.
Though my heart is broken, it is also full of fire.
I apologise to our incredible listeners for my departure, your love of the show means a great deal.
I am so sorry to let you down.
I hope that you can understand my reasoning.
I have to accept that I am not what the current
BBC expects of their freelance presenters.

Despite this I should add that I have always worked far more than my contracted hours to try and ensure the show was always the best it could be, as well as making myself accessible and responsive to the audience wherever and whenever I met them. Every night, we have recorded, I have been filled with determination to make the best show possible. This was not
"just a job"
I hope that with my departure I can be a better ally to the LGBTQ community, to the neurodivergent community, to activists fighting against those who aim to brutalise society, to those currently in prison on hunger strike, and to all those who fight for a more inclusive world.
From many conversations, I know there are many Monkey Cage listeners who support these communities and activists too.
The strawberry is dead.
Long live the strawberry. B

In geometry we call something 'generic' if there is nothing special about the situation. E.g, 3 generic points in the plane don't lie on a single straight line. If you prove a theorem for the generic situation, you have proved it in a special case only because you disregarded the special cases. 🤯

The answer reads "You’re looking for a berry whose name contains three letter B’s—which is quite a rare linguistic quirk! I dug around, and here's what I found:
The only real berry (i.e., a fruit) that fits that description is:
Worcesterberry – a name for Ribes divaricatum, a type of gooseberry native to the Pacific Coast of North America. Conveniently, it contains exactly three “b” characters: Worcesterberry. "
