Interesting that last link there. Makes me wonder about the accuracy of the scenes in Predator with Jesse Ventura :-D Not that it was ever all *that* believable of course.
(and all other films where people carry about mini-guns that are designed to fire from helicopters and stuff)
For movie use, armorers slow down the M134 minigun's rate of fire to conserve ammo, and to allow the spinning barrels to be visible to the movie audience, with a hidden power cable for the firing scenes, and using blank ammo to ease recoil. Nonetheless the prop is still extremely physically demanding, hence the actors wielding it are physically imposing and often have bodybuilding backgrounds. Generally, such depictions will totally ignore the weapon's need for external power, and sometimes even forget that it requires a source of ammunition. In practice, a man-portable M134 minigun would be nearly impossible to manage as an individual infantry weapon, and highly impractical for a human being to either carry or operate. A scaled-down version of the M134, the XM214 Microgun, never reached production status for such reasons.

One item was a pair of automatic pistols, with ammunition.On the moon, I can't see these being much use. In space, equal and opposite reaction would mean that you could fire into space and start yourself moving, very slowly, back towards your spacecraft, if, say, your spacewalk happened to have gone wrong and left you stranded.
Agree that throwing the pistol is likely to be more useful as a means of propulsion. For optimal specific impulse you'd remove the propellant from the cartridges and install it in an appropriately designed solid fuel rocket engine. (Was a lathe and assortment of high-temperature alloy stock amongst the ship's manifest? Every astronaut should have them.) It's all about optimising the velocity of those exhaust gases.
Oh, so they really are doing The Martian[1]...
Hmm, speed of an unladen Apollo astronaut was about 2.2km/h, so that's about 146 hours of moonwalking. Potentially in a suit with consumables rated for 8 hours. I think you'd need to science the shit out of that, especially if your plan hinged on continued availability of sunlight...
[1] Mostly the non-potato stuff that barely made it to the film.
Also, on the moon or in space, would it be possible to fire a pistol without first removing your space gloves? In which case, the escaping oxygen would probably move you further than firing the gun would have done anyway. Although with unfortunate side-effects.
You'd need to be careful where you pointed the gun, anyway. There's nothing much to slow a bullet down in space. You might kill someone on Alpha Centauri in about 1.3 million years' time. For that matter, of course, the gun you threw might hit them on the head, if the universe were to stay around for long enough.Rather pleasingly, one of the scouts suggested you might shoot yourself in the back.

AIUI the lunar gravity is too lumpy to make really low orbits like that possible, which I reckon is proof that the universe has no sense of humour.
Gel water, also called structured, ordered, liquid crystalline, or living water, is a newly identified phase of water that’s not quite liquid, vapor, or ice. Gel water is identified by an extra hydrogen and oxygen atom, so the molecular structure is H302. It’s a highly conductive molecular structure, as the extra hydrogen atoms are constantly moving back and forth between molecules, generating electricity. In this phase, water crystals overlap and interlink like lace or crocheted netting, the way snowflakes do. But unlike snowflakes, which are stationary, gel water creates this structure while remaining in a fluid state. It is not temperature that defines gel water, so much as its shifting molecular structure.
Many people ask if gel water is in a plasma state. While gel water is conceptually similar to plasma, it is highly organized (crystalline-like)—unlike plasma, which has no distinct structure. Gel water can be as thin as liquid, just slightly more silky, or it can develop to be as thick as jello. You know the gel-like substance that forms around chia seeds when you soak them in water? That’s water in the gel phase.
The 'gel-like' substance around chia seeds is the very definition of a gel (hydrated mucins and pectins, not some special new phase of water).
“A go-to hydration tip is to drink at least half your bodyweight in ounces of water,” says Wickham.
Also, the entire '8-glasses-a-day' is a Totally Made Up Thing.
This from another source is a doozy:Quote“A go-to hydration tip is to drink at least half your bodyweight in ounces of water,” says Wickham.
I feel like there's some information missing here. I mean, drinking 40+ litres of water a day would certainly help me stay hydrated, but I don't know why expressing that as 1400oz would make any difference.
Put it into USAnian: if you weigh, say, 180 pounds you should drink 180/2=90 ounces of water. That's about 11 cups. Litres? We don't need those foreign units [about 2.5L - ed.]
One thing I had drummed into me at school - and one of the few things that has stuck with me from science lessons - is that you always state your units when giving any measurements.
Also, the entire '8-glasses-a-day' is a Totally Made Up Thing.Yep, as soon as the topic is hydration, there's going to be bluster, exaggeration, semi-science, pseudo-science and pure marketing.
Humans don't need constant hydration, especially when they're doing nothing more strenuous than sitting at a desk and clicking a mouse.
Nevertheless, inventing an entire new phase of matter is exceptionally bold.

At Scouts last week, I gave the little terrors* a survival on the moon exercise I'd stumbled across. List of items, rank in importance when a hypothetical space ship crashes on the moon etc etc.
One item was a pair of automatic pistols, with ammunition. The "official" answer said that these could be used as propulsion devices, presumably in an action/equal and opposite reaction kind of a way.
Nevertheless, inventing an entire new phase of matter is exceptionally bold.
The thing that makes it really stand out as bullshit is that they can't decide whether it's a new phase of matter or a completely different compound (H3O2) that isn't actually water and has different physical properties to water.

Maybe they were holding the compass upside-down or didn't want to give the house prices cancer or something?
There's an argument for encouraging west-facing solar panels, in order to give greater output when the grid needs it most.
A propos compasses. I may or may not work for a teaching establishment that has a name that is synonymous with a certain meridian. There is a scupture on the lawn of said institution that is meant to be a sundial. Whoever installed it needed a bit more supervision- north points east.

Where to start? Titanium dioxide is also used in toothpaste (although shortly to be banned by the EU for those still there). Does that mean it keeps your teeth clean while you're running?
Just slather on some Sudocream.
Titanium white is a common artist's colour. I'm not sure whether it's also titanium dioxide but I'd presumed paint, sun screen and toothpaste all worked by reflectivity.

I'm sure I've previously mentioned my schoolmate who once confessed to doing that.
I can think of many things that might have the properties of a reasonable tribological agent for intimate purposes, but toothpaste doesn't leap to the top of that list. I'd probably advise against, and not from personal experience, Swarfega. Growing up, we had tubs of that everywhere, mostly because my mother's brother-in-law worked in the factory and kept bringing it home.
Never mind toothpaste (or paint, or anything else where it's used as a pigment), they've got the principle of operation completely wrong.
Is that the orange or green swarfega? Asking for a friend.
The Environment Agency...asked people not to put anything containing chemicals down those drains.

Anyway, here's another that I read recently. It's from a short story by Hemingway. I can't find the exact quote now but he described a gun as "having a muzzle velocity of two tons".
Macomber did not know how the lion had felt before he started his rush, nor during it when the unbelievable smash of the .505 with a muzzle velocity of two tons had hit him in the mouth, nor what kept him coming after that, when the second ripping crash had smashed his hind quarters and he had come crawling on toward the crashing, blasting thing that had destroyed him
The cartridge's claim to fame was its use by the fictional character, Robert Wilson, the hunter of Ernest Hemingway's short story "The Short Happy Life of Francis Macomber (https://en.wikipedia.org/wiki/The_Short_Happy_Life_of_Francis_Macomber)".
I think Hemingway knew about guns
and this is probably the way gun people talk
(with the actual mass of the bullet being a known factor).
The wiki page for the cartridge suggests a typical muzzle velocity of 2,100-2,300 ft/s (640-700 m/s) - how the hell Hemingway gets from that to two tons is anyone's guess!
It’s a bit late for maths, but could two tons be about the pressure that’s causing the velocity?

No, non, nein, nyet and fucking nope, they wouldn't if they knew what they were talking about. They'd use the correct unit of measurement.Quote(with the actual mass of the bullet being a known factor).
Mass only comes into it someone is talking about muzzle energy, which is the kinetic energy (Ek) of a projectile as it leaves the gun barrel. Kinetic energy would be measured either in foot-pounds force or in joules.
But as Ek = 0.5 x mv2, where m is mass and v is velocity, the fact that it is proportional to the square of the velocity should be a clue as to what is a bigger factor.
Fair point :)It’s a bit late for maths, but could two tons be about the pressure that’s causing the velocity?
What's pressure measured in, though? ;)
I think Kim's closest to the mark with her Kessel Run reference, in that Hemingway either got his units mixed up, or he pulled the "two tons" figure from his backside.
And frankly, I've wasted enough time on this already...

Basically, they aren't particles or waves, they're just metaphors for how they behave under specified conditions (similarly with spin, colour charge and other fancy aspects of quantum unreality). We just don't have an understanding or description of what they really are or even if they really are. It's all rather complicated. Wait till you learn about the fact a lot of matter is made out of things that only exist virtually.
The wave/particle conundrum has fascined me for half a century.

They behave like both particles (things with very specific locations and dimensions) and waves (coherent phenomena but spread out over considerable areas) at the same time is about as near as we can get. And, as you say, they do that even if you reduce the amount of light so much that there is only one photon (particle) present. The sea is lots of molecules (particles) making waves together, of course; it's as though you reduced the entire ocean to one molecule of water, and still got the faint marks of waves left on the beach.
I've always found the concept rather charming.
I've always found quarks to be a bit cheesey

Listening to Hancock's "The Radio Ham" on BBC Sounds today, The Lad Himself says he's broadcasting on the short wave band at 10.4m at 250 mega cycles per second.
Speed of propagation is wavelength x frequency, so 10.4 x 250 x (10^6) m/s = . Or 2.6 x (10^9) m/s. Say 8.7 x the speed of light.

Stress and anxiety can have a detrimental effect on our skin. I think we can all attest to that over the last two years. Look at Dr Masaru Emoto’s work on the study of how emotions affect the molecular formation of water, and we’re 60% water. Being a happy human keeps us feeling and looking healthy.
Good quality shilajit, CBD and lion’s mane are my desert island supplements. Shilajit is a plant resin and one of the most potent antioxidants there is, so it can help protects cells from damage. I studied CBD and became a certified expert, so I’m a big advocate. It can help with sleep issues, depression and anxiety. It’s also neuro protective, anti-bacterial, anti-convulsant, anti-nausea and great for skin health. I take lion’s mane mushroom supplement for focus, clarity and brain health.

0.33kW of instantaneous power, enough to briefly sustain around 750 homes
It's now saying 250kW, which seems more reasonable. In as much as "sustaining homes" is a useful measure of anything.

*peers at monthly electrosity stats*
Power: Average:488.64W Max:5990.20W Min:0.00W (Ignore that last one, the monitoring got unplugged.)
So yeah. Not enough to keep our house running. But we're heavy users with a lot of computer equipment, I can imagine many people are well under a third of a kW. No idea how many really heavy users there are (big families, storage heaters, hot tubs, etc.), and where the national average might be. Possibly too much to hope that they've got that figure from somewhere sensible...
ETA: I note Ripple are using 2900kWh/year as their 'medium' average consumption (https://rippleenergy.com/how-it-works). That's 331.1W.
Obviously peak demand complicates things. But it's not like you're really trying to power a village with an electric crane anyway...
On the gripping hand, unless you're comparing electricity bills, who has an intuitive sense of how much power a typical home uses on average? At least 1-bar electric fires are meaningful.
In addition to long division, to this day I can't my times-tables either. I can't say the omission of either has really held me back.

I remember consistently misreading cwt as kilowatt. Not only for the obvious visual reason but because hundredweight just weren't, and aren't, a part of daily life. I can't remember where I was seeing this; pretty sure it wasn't at school, must have been some sort of old documents or something. In fact I'd say hundredweight are one of the most contextually confusing measurements; not only the UK-US difference but in a metric context it can be either 100kg or 50kg (as a metricised equivalent of the imperial measure). I suppose centner and quintal at least avoid that confusion.

A US study that followed more than 18,500 male doctors (all aged 40 or over) found that those who took multivitamins for at least 20 years were almost half as likely (44%) to experience a heart attack or stroke as those who hadn’t taken a multivitamin long-term. ‘This suggests the long-term use of supplements appears to offer significant cardiovascular protection,’ explains Dr XXXX. ‘Consider taking a multivitamin and mineral supplement as a nutritional safety net to help safeguard against diet deficiencies.’
In this long-term prospective study in initially healthy men, multivitamin use for ≥20 y was associated with a lower risk of major CVD events.

This may prove useful to some of you some day, perhaps, in a somewhat bizarre set of circumstances.
Working on a health blog today, which includes this snippet...Some 6th form science understanding would suggest that the sort of people who take vitamin supplements for the last 20 years (e.g. starting in their 20s) would tend to be more health conscious and will likely do other things that will be good for their health, hence less chance of heart attacks. Correlation vs causality.

It is technically a confounder, but a core reason while the vast majority of correlations aren't causal relationships. Of course, if most of the world knew this, social media would collapse.

See also The Oven. I tried and tried to explain to Mrs B that turning the oven to 240 won't get it to 180 any quicker.
Yes, I've long thought that by the time people finally get the message about thermostats, thermostats will no longer be simple thermostats.All that was in the back of my mind when I put forward my proposal up there and was thinking how to word it. But then my attention wandered to a glass of Rioja.
Doesn't it also depend how you're using the heating? An oven you're almost always using from cold, so it makes no difference. But if you turn your heating on and off more frequently than the time it takes to return to ambient, than it's starting from a slightly higher temp if you last had it at 21 rather than 20. Whether it's a noticeable difference is another question.
If you have a mechanical thermostat, turning it from 20 to 21 might not be enough to flip the bimetallic strip straight away, whereas turning it to 24 would flip it immediately. Ergo turning it up higher heats the room quicker.
Setting the room thermostat to a higher temperature has no effect how long it takes to get to temperature.
Setting individual radiator thermostatic valves to the maximum WILL heat up the rooms faster. There is a case for having all radiators open to full in rooms that are frequently used. Put thermostat in a hallway or something, set the temp lowish (for your standards), and open rad valves right up in the living room, kitchen. The living room and kitchen will get toasty warm, the rest of the house tolerable.
If you have rooms with rad valves cranked down, and the stat is in your 'warm' room, I'd say there is a fair possibility of getting cold damp areas in your house. Depends on the temp gradient in the house.Setting the room thermostat to a higher temperature has no effect how long it takes to get to temperature.

On the first point, is that still true in this era of smart modulating boilers?
My boiler controller talks to the internet to find out what the outside temp is, and is supposed to learn how long our home takes to get up to temperature, so it surely should be modulating the flow temp to meet the required diff T?
On the 2nd point, I don't get that. My method is to have the stat in the room I want to be warmest (i.e. the lounge) with the rad valve fully open and turn the valves down anywhere I want cooler. (They always say the valve should be fully open where the stat is),
Of course when we had the wood burning stove in the lounge at the last place I moved the stat to the bedroom. (My brother complains the rest of his house is freezing when his stat is in the lounge next to the stove)
That could mean domoic acid adapts well as ocean waters heat up
Surely X amount of water requires Y amount of energy to boil regardless of whether you boil it all at once or in separate batches?There are losses from heating excess water and the kettle itself, and some losses from the kettle shutting off after the water boils.
I suppose there are perhaps some losses due to inefficiency, but does boiling all the water at once reduce those inefficiencies at all?

The thermos will lose heat, but the tea drinker may accept tea made with not-quite-boiling water (YMMV) and therefore heat lost from the thermos may not be extra electricity used.

Speculation: Some people don’t boil exactly the tight amount of water in a kettle. Better to boil excess water once, rather than twice.

"Why you shouldn't truncate the Y axis"No, the problem there is truncating the Y axis but not truncating the trunks (or the legs).

Cudzo linked to an article on the best powerbank thread about a very light one. It contains this gem:Yeah, I remember cringing a bit at that when I read it.

It kind of shouldn't be, but it is the norm and it's more easily understood than 20 Ah, simply through familiarity (in this context).

Anyway, not keen on "k" masquerading as a unit, eg 200k (k£ or km).
Just an abbreviation for "thousand" though, so can't really complain.
Yes, they mean kW. I can sort of see the reason for kWh / h, because electricity meters read in kWh (or units of electricity), and EV batteries are rated in kWh. Adding 50 kWh to a car battery will increase the reading on the meter by (about) 50 kWh, however fast it is done.On a related theme, is anybody else as irritated as I am by the common use of 'kW' for battery capacity and 'kWh' for charge rate (or even worse 'kW per hour'! :facepalm:) whenever EVs get discussed?

This article (https://www.theguardian.com/business/2023/oct/09/worlds-largest-offshore-windfarm-project-starts-powering-uk-grid), when it first came out had the sub-headlineI think that 'wind competing' is a jargon phrase for 'competing to supply', because at any one time the National Grid will 'call' for supply from multiple generators. Some generators will be spun down, because they aren't needed.Quote from: The GuardianFirst of 277 turbines goes into operation at site that will produce enough energy for 6m homes a year
And repeated the howler throughout the text. Thankfully it's been corrected now. What even is a "home per year"?
It's still there in this other article (https://www.theguardian.com/environment/2023/sep/08/biggest-clean-energy-disaster-in-years-uk-auction-secures-no-offshore-windfarms) from SeptemberQuoteUp to 5 gigawatts of offshore wind was eligible to compete, which could have powered nearly 8m homes a year.
I also like the idea of wind competing.
Battery technology. I am sure it has plenty to offer, just needs investment.When you compare battery storage with hydro dam storage, it doesn't stack up.

Batteries require a lot of resources to build. Even the iron or vanadium / air batteries.
Dams require water and a bit of concrete (yes, and suitable land, but that exists).

I thought that the rush for hydroelectric in the last century had used almost all the good locations?
I would imagine that an awful lot of reservoirs would be suitable for conversion to energy storage. The added bonus being that they are spread around the country so would be good generally for regionalised energy distribution.But we also need more reservoirs for drinking water. Can one reservoir be used for both purposes? I don't see why not, but there might be a reason.
And according to that Wikipedia, Britain is Europe's nexus of HVDC transmission, albeit not overhead:

The economics shift further in DC's favour as soon as the medium you're stringing the cables through is water, rather than air, as the losses from AC become greater.

That's something I hadn't heard.
Some dielectric effect coupling with the water?
There is a rumbling of concern about the effect of electric cables on sealife.
They've found that crabs are reluctant to cross the HVDC cables, which is an issue when the crabs migrate for breeding.
The specialist global investment manager revealed the Kent-based project, which consists of 373MW of solar and “more than” 150MW of battery energy storage, is expected to be fully completed by the end of 2024.
I think burying the cables would be not only a whole lot more expense, it would introduce an whole extra level of sea-bed disturbance. Something similar is being observed in some places with buried (in land) cables and pipes.
More electrically based nonsense:QuoteThe specialist global investment manager revealed the Kent-based project, which consists of 373MW of solar and “more than” 150MW of battery energy storage, is expected to be fully completed by the end of 2024.My bold.
That from a solar power trade comic, where you might hope they know the difference between MW and MWh. I guess it's a regurgitated PR piece that was written by someone who doesn't.
You'd assume wrong.I think burying the cables would be not only a whole lot more expense, it would introduce an whole extra level of sea-bed disturbance. Something similar is being observed in some places with buried (in land) cables and pipes.
Pipelines are generally trenched and protected against overtrawling. I'd have assumed the same kind of protection for cables

The clue's in the first part of the sentence (my bold).

seabed Power cables are just draped on the seabed. Very vulnerable to anchors and beam trawling.
Hence why Lewis lost its interconnect a couple of years back.
Article about moving bagged waste along 'vacuum' tubes said that the bags were moved by negative pressure.
There's a whole appendix to the e-book edition of Neal Stephenson's “Cryptonomicon” dedicated to the subject of international telecommunications cables.
I don't think it's wrong to refer to gauge pressure (which is clearly what they mean in this context) as negative. Absolute pressure would be another matter.Indeed - so say so.

Seems that very few people know how a 'vacuum' cleaner works.
...'Vacuums don't suck'...

this grinds my gears.
'Vacuums don't suck' is something I'd like taught in all schools.
Regardless of the use of negative, the bags are definitely not moved by negative pressure, but by a pressure differential. In lots of situations, they are moved by the weight of the atmosphere.
^^^Yebbut positive and negative have meanings beyond mathematics. If you look at e.g. Chambers, being numerically greater than zero is only the 10th meaning on the list of definitions. #1 is 'sure, certain or convinced'. Similarly, the mathematical meaning of negative is only the 6th definition thereof.Don't go bringing common sense into a thread about science (or any thread where "cringe" is involved)!
Use of positive and negative could occupy a thread - eg, having covid test is +1 (positive test); not having test is 0; how does one have/not have -1 covid test (negative test)? Results are not tests, so positive test could yield zero covid.

There's a strong positive = good association in BSL. Which was a big problem in the Deaf community in the early days of the previous pandemic.
Climate change is driving up sea surface temperatures as the warming gases emitted when we burn oil, coal and gas are absorbed by the oceans.Well, I know CO2 is absorbed into the ocean, but AFAIK, that doesn't drive up the temperature of the water, just makes it slightly acidic.
On a related note, I had one refuse to recognise a bag of keto-snacks on the grounds that someone had torn it open and helped themselves to two of them, which I only noticed when I discovered the hole on the third attempt and counted 10 rather than the expected 12.
I then had to explain the problem to the assistant, who was baffled that I'd noticed.
