'Water is scarce in Mauritania and people have little choice but to bathe, wash clothes, care for their animals, and cool off in the same pools. But the water that brings relief also carries schistosomiasis, a parasitic disease that silently damages the kidneys, stunts growth, impairs learning, and steals futures.

Through our collaboration with the Ministry of Health, Amadou (pictured*) received treatment, and he recovered. But many children in Mauritania still require it. Without continued access to treatment, Amadou and thousands like him remain at risk every time they enter the water.

When people cannot avoid exposure, access to safe, effective treatment is their best protection. A single donation can help protect children like Amadou and support their health at a critical stage in their childhood.' ... 'Choose to Treat appeal'

'Oh Thomasina!' Such a drama in a diagram

Arcadia

Last evening I really enjoyed a performance of Tom Stoppard's Arcadia at the Duke of York's, or soon to be - The Tom Stoppard Theatre:

Act I, Scene 2  

'Septimus ... You should no more grieve for the rest than for a buckle lost from your first shoe, or for your lesson book which will be lost when you are old. We shed as we pick up, like travellers who must carry everything in their arms, and what we let fall will be picked up by those behind. The procession is very long and life is very short. We die on the march. But there is nothing outside the march so nothing can be lost to it. The missing plays of Sophocles will turn up piece by piece, or be written again in another language. Ancient cures for diseases will reveal themselves once more. Mathematical discoveries glimpsed and lost to view will have their time again. You do not suppose, my lady, that if all of Archimedes had been hiding in the great library of Alexandria, we would be at a loss for a corkscrew? ...'^ p.20.

 Act II, Scene 3

'Lady Croom We are intruding here - this will not do, Mr Hodge. Evidently, nothing is being learned. (To Noakes) Come along, sir! 

Thomasina Mr Noakes - bad news from Paris! 

Noakes Is it the Emperor Napoleon? 

Thomasina No. (She tears the page off her drawing block, with her "diagram" on it) It concerns your heat engine. Improve it as you will, you can never get out of it what you put in. It repays eleven pence in the shilling at most. The penny is for this author's thoughts. 

She gives the diagram to Septimus who looks at it.' p.74
...
Now Septimus retrieves his book from Thomasina. He turns the pages, and also continues to study Thomasina's diagram. ... 

Septimus Why does it mean Mr Noakes's engine pays eleven pence in the shilling? Where does he say it? 

Thomasina Nowhere. I noticed it by the way. I cannot remember now. 

Septimus Nor is he interested by determinism -------

Thomasina Oh... yes. Newton's equations go forwards and backwards, they do not care which way. But the heat equation cares very much, it goes only one way. That is the reason Mr Noakes's engine cannot give the power to drive Mr Noakes's engine. 

Septimus Everybody knows that. 

Thomasina Yes, Septimus, they know it about engines! 

Pause. He looks at his watch 

Septimus A quarter to twelve. For your essay this week, explicate your diagram. 

Thomasina I cannot. I do not know the mathematics. 

Septimus Without mathematics, then.' p.75.

P.S. There isn't a domain called 'bin' but there is plenty of waste.

There isn't one called denial, or ignorance either, but you will find them in abundance too.

Rest assured (if you still can!) that each domain carries its own truth. 

Single, dual aspect in architecture. What of care?

'The challenge of overheating in Britain is our buildings are built to retain heat in our temperate climate. Energy efficiency regulations for new dwellings now require high insulation and few drafts to reduce the need for heating in winter, but broadly make it harder to cool homes in summer. Residents of cities are particularly vulnerable to overheating due to urban heat island effects.

There are two ways buildings can be cooled – mechanical methods (primarily air conditioning) and passive cooling methods that use the design of the building to limit heat gain and retain cooler air inside the dwelling.

Passive cooling is much easier in dual-aspect dwellings with windows on multiple external facades, which as shown in Figure 1, are contrasted to single-aspect flats that face out on to only one external facade. Dual aspect allows breezes to blow through dwellings and easily exchange stuffy indoors air for cooler air from the outdoors. Even if outside temperatures are high, cross-ventilation or overnight air exchange and limits to solar gain (daylight indoors) can keep indoor environments cooler than the outdoors.'

	Single and dual aspect flats

In Hodges' model at least, we seem to have dual aspect covered. 

That's why we say the model is situated.

Graphene just broke a fundamental law of physics

Graphene just broke a fundamental law of physics.

Its electrons just did something physicists thought was impossible. For nearly 200 years, metals have obeyed the Wiedemann-Franz law – the rule that electrical conductivity and thermal conductivity always rise and fall together. 

But in ultra-clean graphene, researchers at the Indian Institute of Science found the opposite. As electrical conductivity increased, thermal conductivity dropped, shattering a principle taught in every physics textbook. 

The key lies at the “Dirac point,” a strange electronic tipping point where graphene is neither a metal nor an insulator. Here, electrons stop behaving like individual particles. Instead, they flow collectively as a nearly perfect fluid – a state called a “Dirac fluid.” 

This discovery doesn’t just rewrite the rules for graphene. It provides a tabletop window into extreme physics usually reserved for black holes and high-energy colliders. Scientists say this behavior could help probe mysteries of quantum entanglement, black hole thermodynamics, and the very fabric of matter itself.

While I can't fully understand this paper (even the abstract!), I realise that it is taking what seems a long time^ for industry and business to understand and realise the potential of graphene in industrial and technological applications.
Hopefully, applications will emerge, that are beneficial to all. Reducing energy use, improving efficiency, removing pollutants even more effectively, imcreasing the durability and hence lifetime of materials and products, and more.	Also, marvellous to see global collaboration at work, as science continues to asks questions. ^I could have written exploitation there, but could we put the collective and planetary first?

Blockchain Revolution

"The mechanism for reaching consensus is critical. 'Consensus is a social process,' blogged Vitalik Buterin, pioneer of the Ethereum blockchain. Human beings are fairly good at engaging in consensus . . . without any help from algorithms." He explained that, once a system scales beyond an individual's ability to do the math, people turn to software agents. In peer-to-peer networks, the consensus algorithm divvies up the right to update the status of the network, that is, to vote on the truth. The algorithm doles out this right to a group of peers who constitute an economic set, a set that has skin in the game, so to speak. According to Buterin, what's important about this economic set is that its members are securely distributed: no single member or cartel should be able to overtake a majority, even if they had the means and incentive to do so.

To achieve consensus, the bitcoin network uses what's called a proof of work (PoW) mechanism. This may sound complicated but the idea is a simple one. Because we can't rely on the identity of the miners to select who creates the next block, we instead create a puzzle that is hard to solve (i.e., it takes a lot of work), but easy to verify (i.e., everyone else can check the answer very quickly). Participants agree that whoever solves the problem first gets to create the next block. . . . For each block they find, miners receive  bitcoin as a reward." p.31.

"Blush is a radiator by Icelandic designer Thorunn Arnadottir that is covered in thermochromatic paint and both looks like and simulates capillaries. She says, 'Blush is a very important organ of the house. Regulates the temperature and keeps it warm and alive. Blue when cold, but blushes with red when warm.'"
