@SashaSagan It's just as well that there is no charge (I hope! 🙏🏻) for quoting someone, or I would have incurred significant debt by now, given how often I have quoted your father.
I'm sure you already know his profound impact on so many of us.
My first "encounter" (via TV) with him was when he did the Royal Institution Christmas Lectures in 1977. I was a geeky schoolkid interested in science.
Your dad was inspirational.
I didn't become an astronomer, but I did subsequently navigate my way through a couple of chemistry degrees.
His beautful book dedication to your mum in "Cosmos", is my favourite such dedication of all-time. 😊
It would have been nice if the world had managed to have his wisdom around for longer, but we're lucky that we had him at all.
I wish I had managed to meet him sometime, even briefly at a book signing, to express how much he meant to me.
Alas, I never did.
So, please forgive this somewhat rambling discourse, but your dad was (and is) a real hero to me, both for his ability to communicate science in a way that inspired, and for his humanity.
Best wishes from Scotland. 🏴

Since Covid first manifested its ghastly presence on these shores, I think it fair to say that most of us have gained an understanding of the R number.
In simple terms:
R < 1.0 = Good! ✔️ 👍🏻
R > 1.0 = Bad! ✖️ 👎🏻
Obviously, it has ebbed and flowed in response to: lockdowns beginning; lockdowns ending; vaccine rollout; and social bubbles etc.
However, by this point, few can be in any doubt that R being significantly above 1.0, say around 1.5, is VERY bad indeed. 🤮 #ExponentialGrowth
We have been incredibly lucky to have several highly effective vaccines appear, so quickly.
Just imagine what 2021 would have looked like in the face of the #Delta strain, without ANY vaccines? 😱
But our “leaders”, basically opted for a “vaccine only” strategy. 🙄
Exponential growth, BUT you can still go to panto? 🤦🏻♂️
As a nation, we’re approaching the idyllic halcyon period between the moment the brakes get slammed on for an emergency stop, and the moment we fly through the windscreen (because, as you know, seatbelts are only for wimps).
I just heard @SCrabbPembs on #DailyPolitics saying Plan B measures were already in effect in Wales and hadn’t curbed the spread of Delta (which is true).
Logic might then suggest, that FAR greater restrictions might be needed to curb the spread of a MORE transmissible virus? 🤔
Apparently not. It seems that (for now) is just crazy talk among our political class. 🤷🏻♂️
Watching the news coverage on the Plan B shenanigans tomorrow is just surreal. 🤦🏻♂️
“Will there need to be more restrictions before Christmas?”
‘But Boris Johnson may have a get out from claims he broke the law - because there is an exemption for “a vehicle being used for police, fire and rescue services”.’
An utterly selfish, narcissistic, arsehole always looking to play a “get out” card. 🤬
Yesterday, I learned a new Covid-related skill, how to calculate the doubling time for an exponential growth curve (in this case related to #Omicron cases growth in the UK).
Yesterday, that value worked out at 2 days.
Adding in today's data, now makes it a value of 1.4 days! 😱
My instruction manual for learning how to do this calculation, was this amazingly helpful video by @pk_kent 🙏🏻
