Bunch of saddos. [The Science Unit, that is, not the Pussycat Dolls, who I’m sure are quite charming.]

This morning’s guest on is colour and vision scientist Anya Hurlbert. Among other things, we talk about ‘that dress’ -

For example, the UK has a higher proportion of children living in poverty than Poland. And people in regions who voted Brexit and switched from lab to con in last GE have been hardest hit by cuts and austerity and seen biggest fall in life expectancy.

Austerity blamed for life expectancy stalling for first time in century. This landmark report by Sir Michael Marmot (a world leading epidemiologist and one of my first guests on the Life Scientific) makes for sombre reading

Of course I agree with your first part. But apparently we DON’T all know it’s not magic, judging by the tweets I’ve received seemingly appealing to perpetual motion. In any case, my original criticism was of the ad calling car “self-charging hybrid”. I know it’s just marketing...

I read Consciousness Explained when it first came out nearly 30 years ago. To a large extent it’s shaped my thinking ever since. This review is a great summary. And Dan Dennett is still one of my favourite ever guests on The Life Scientific.

Exactly. The Twitter shouters are trying to turn it into a debate about efficiency. Regenerative braking is hardly new. I stand by my point: unlike plug-in electric cars, this runs (more efficiently) 100% on petrol. Advert is trying to sell the dynamo as an innovation.

For goodness sake, they are advertising a car as being somehow more convenient than plug-in to charge battery. Efficiency aside (like any hybrid) the car’s energy comes 100% from burning fossil fuels. That is all.

Sorry, but that is just bad physics. If it is KE it recovers (and not, say, waste heat from brakes) to turn into electricity by the generator then the car will lose KE (slow down). You do NOT gain anything. Law of Consrrvation of Energy.

This is a nice podcast chat I did covering a lot of the stuff I discuss in my new book

This is a lovely initiative. Adelard of Bath (what do you mean you've never heard of him?) was one of the greatest English Medieval scholars - in my view the greatest before Roger Bacon.

Thought you might pipe up. But it’s one my favourite (and crude) physics jokes. Fokker-Planck? No thanks, I’d get splinters in my...

Anyway I’m now reading a paper entitled “Quantum and classical Fokker-Planck equations for a Gaussian-Markovian noise bath”. Happy to discuss.

If only. This started because the advert was selling the advantage of NOT having to access the grid (hence the ‘self-charging’ marketing). 😏

Also, here’s a thing [stop it Jim, get back to work]: if it’s efficiency that’s all that is gained, try driving less.
