Brum is amongst the best cities to visit this winter 👏🏻
The ONLY UK city on the Telegraph’s list ✔️
We’ve worked hard to bounce back as a global destination, capitalising on the Commonwealth Games ✅
Despite the city council’s challenges, there’s still much to be proud of 📈
These days, new skills are relevant for less and less time. Continuous learning is more important than ever. But how do you know what to focus on? https://t.co/mDk1pHzWIH
With Bonfire Night just around the corner, we’re reminding you to keep safety in mind by following the Firework Code and attending public displays where possible:

Great and somber morning/afternoon representing @WarksFireRescue at the National Firefighter Memorial, well attended, well delivered and well worth it (If a little on the warm side) 🚒🔥🚒🔥🚒🔥🚒🔥🚒🔥🚒🔥
Elon Musk on the importance of First Principles thinking:
“I think people’s thinking process is too bound by convention or analogy to prior experiences. It’s rare that people try to think of something on a first principles basis. They’ll say, “We’ll do that because it’s always been done that way.” Or they’ll not do it because “Well, nobody’s ever done that, so it must not be good. But that’s just a ridiculous way to think. You have to build up the reasoning from the ground up—“from the first principles” is the phrase that’s used in physics. You look at the fundamentals and construct your reasoning from that, and then you see if you have a conclusion that works or doesn’t work, and it may or may not be different from what people have done in the past.
I think it’s important to reason from first principles rather than by analogy. So the normal way we conduct our lives is, we reason by analogy. We are doing this because it’s like something else that was done, or it is like what other people are doing… with slight iterations on a theme. And it’s … mentally easier to reason by analogy rather than from first principles. First principles is kind of a physics way of looking at the world, and what that really means is, you … boil things down to the most fundamental truths and say, “okay, what are we sure is true?” … and then reason up from there. That takes a lot more mental energy.
Somebody could say — and in fact people do — that battery packs are really expensive and that’s just the way they will always be because that’s the way they have been in the past. … Well, no, that’s pretty dumb… Because if you applied that reasoning to anything new, then you wouldn’t be able to ever get to that new thing…. you can’t say, … “oh, nobody wants a car because horses are great, and we’re used to them and they can eat grass and there’s lots of grass all over the place and … there’s no gasoline that people can buy….”
First principles thinking example about battery packs:
… they would say, “historically, it costs $600 per kilowatt-hour. And so it’s not going to be much better than that in the future. … So the first principles would be, … what are the material constituents of the batteries? What is the spot market value of the material constituents? … It’s got cobalt, nickel, aluminum, carbon, and some polymers for separation, and a steel can. So break that down on a material basis; if we bought that on a London Metal Exchange, what would each of these things cost? Oh, jeez, it’s … $80 per kilowatt-hour. So, clearly, you just need to think of clever ways to take those materials and combine them into the shape of a battery cell, and you can have batteries that are much, much cheaper than anyone realizes.”
I have missed more than 9,000 shots in my career. I have lost almost 300 games.
26 times I have been trusted to take the game's winning shot and missed.
I have failed over and over and over again in my life, and that is why I succeed.

Can't believe another near miss today with children seen playing on frozen water in Leicester. Fortunately the children were called from the ice by @leicspolice and given some strong words of advice. Please advise your children not to play on frozen water - it is not safe
