New Theories / Re: How does Noether's theorem apply to moments of time?

This is a public warning. Cool it, guys. Please stick to the subject and avoid personal accusations.

Humans have directly modified 77% of the land surface and 87% of oceans (Watson et al., 2018).
That's pretty remarkable, considering that less than 25% of the land and less than 1% of the sea is inhabited or even regularly visited by humans.

We have indeed modified the 25% we occupy. It's called agriculture. Every animal modifies its environment. It's called living.

Just Chat! / Re: Energy and healthwise, what is the best thing to eat for breakfast?
« on: 09/08/2022 21:13:51 »
Monday to Friday: Porridge, eggs, bacon, sausage, baked beans, black pudding, fried bread, coffee.

Saturday: Grapefruit, devilled kidneys,scrambled egg, white pudding, toast, champagne.

Sunday:  Orange juice, kedgeree, asparagus omelette, haggis, clouttie pudding, Guinness.

Substitute oysters, raw or cooked, for any item at any time. Add spinach and/or Hollandaise sauce to taste - eggs Benedict if you are in a hurry.

Breakfast is the key to good mental health. Best if it lasts for at least an hour, after which you spend the rest of the day outdoors digging, shooting or fishing for your dinner. Substitute coffee for alcohol if your weekend pursuit is flying: you can always turn up drunk at the office - nobody will notice.

Physiology & Medicine / Re: Is extreme lifestyle changes a primary cause of postpartum depression?
« on: 09/08/2022 20:59:10 »
The environmental factors are all important but to some extent also applicable to male partners, most of whom step up to the plate but a significant number run away. I wonder how the male statistics stand up against those for female PPD?

"Brain chemical imbalance" looks like pseudomedicine, to be followed by a list of ancient curative herbs and potions. There are certainly profound hormonal changes throughout pregnancy and early post-partum, but a species (or even a genetic line within that species) in which these ultimately led to the incapacity or unwillingness of the mother to nurture the baby,  would quickly  become extinct. We know of occasional rejections among farm animals but their lifestyle changes are far less profound than for humans, and the inherent commitment to the newborn is much shorter.

In summary, I've seen it, I don't know the answer, a bit of statistical analysis might be interesting, and I'd counsel against using language that might be construed as "alternative".

World is a terrible place when not everyone plays cricket
My father used to point out that no cricketing nations had ever declared war on one another.

For the uninitated, the Indian Premier League is a major tournament between teams of world-class players who put themselves up for auction by the rival sponsors each year. The year after some Pakistan-based scum blew up a hotel in Bombay for the greater glory of their superstitions, nobody bought any Pakistani players. In response to such national humiliation, the Islamabad government swiftly issued an apology and began to crack down on religious terrorists. Equilibrium has been restored.

" The UK receives hydroelectric power from Norway through a subsea interconnector cable running beneath the North Sea. However, water levels in southern Norway have been so low this year that the country’s government could put its own consumers ahead of international customers."
At this moment, the UK is actually supplying electricity to Norway, Ireland and France. The maximum capacity of each link is 1.5 GW in either direction. Sustainable? No, since nearly 50% of UK generation today (35 GW total demand) is fossil-powered.  Under blazing  sunshine we have  an estimated 6 GW of solar power (60% of installed capacity) and less than 3 GW of wind (12% of capacity).

So, in a nutshell, it seems that the most reliable renewable of all, Norwegian hydroelectricity, is not reliable.

But yes, it could have gone the other way, a Japanese population believing in 'divine rights', refusing a surrender. And in that case, what would USA have done? I think I can guess it.

No need to guess. At the time, my dad was exercising tank squadrons in India and the Boss's dad was manning a "conventional" B29 somewhere in the Pacific, in preparation for the seaborne invasion of Japan. Like D-day and the march on Berlin  but a lot bloodier. The estimated casualty count was at least 3,000,000 in a 2 - 4 year campaign.

It's the best way. And indeed the entire ethos of warfare - it's not like cricket.

The concept of negative temperature derives from a definition of temperature in terms of entropy. All it means is a condition where adding energy to a system decreases its entropy.

I don't think anyone can 'win' a nuclear war.
The western allies have already done so.

Still wearing my linguistic pedant hat, what you are actually doing with squeezed states is reducing the indeterminacy of one vector of a phenomenon in order to reduce the uncertainty of your measurement. It's remarkably like heterodyning.

Just thought of a macroscopic analogy. How do you count sheep? In a field, they are all milling about in various directions so you don't know if you've counted one twice, or missed out a few. So you can either take a photograph, which tells you how many were there at the time you took the photo (but you don't know where they are now) or you herd (squeeze) them through a gate and count them one at a time into separate pens. Well, it's no worse a model than the bouncing photon!

The UK need its atom bombs, nuclear missiles etc, to 'defend itself'.
I have always asked "against whom?" The UK cannot in any sense win a nuclear war with Russia or the USA, and is unlikely to become involved in one with any other nuclear power: the big ones own most of UK industry and infrastructure, and the smaller ones are in general considered friendly. Threats to the British Way of Life (which I presume is what we are defending) nowadays come mostly from religious perverts with no specific geographical base.

So tell us more about your real democracy. Put every public policy decision to a public vote?

The ultimate democracy is a free-for-all with no centralised functions or services, hence no taxes, and everyone spends his money exactly as he sees fit - a true anarchy. Which is all very well until an organised and disciplined group of scum decide to attack you and steal whatever you hold dear. So you need a defensible boundary and an organised defence. Do you go with the National Rifle Association and  insist that everyone has the right to kill anyone else, or do you organise an army to defend a territory? That needs taxation and a hierarchy.

The Environment / Re: Global Warming. long term effects.
« on: 07/08/2022 15:42:34 »
...said the Pope to Galileo.

Problem is that there is no money to be made from a declining population, or from claiming that there is no impending crisis, and every politician has to say "growth" ten times a day to earn his salary. The teeming masses have every right to want a western standard of living, and that can't be achieved with renewable energy alone, so fossil fuel consumption must rise until it is all exhausted. So we are doomed in the short or long term.

If the emperor has no clothes, it is up to everyone to say so. And just for once, acsinuk has said it.

As of July 12, 2022, 1,016,929 gallons of oil have been collected from the MC-20 site” over more than three years, the Coast Guard said in a news release. That amount — more than 3.8 million liters — would fill about 1.5 Olympic swimming pools. The Coast Guard said that the containment system it ordered is collecting an average of about 900 gallons (3,400 liters) of oil a day.  "
Wow! A journalist who can do arithmetic - or at least read a press release! But so what? Is that a little or a lot? Are they burning more oil by collecting it than they collect? 900 gallons won't push a big ship very far.

For how long every 7 seconds? It's difficult to resolve brain waves to better than a millisecond, but that's quite long enough to think about everything else.
