Does there seem to be more cancers occurring per individual than ever before, or is it that our ability to detect has just improved? Wherever I look I can see people impacted by cancer.

I suspect it's because people are no longer dying younger of all the other things we now have treatments for.

I don't think it is particularly worse. It's always been thus

I respectfully disagree because we're subjecting ourselves to more cancer causes. We're consuming more carcinogens, subjecting ourselves to greater levels of UV and radiation.

Wasn't so long ago where being out in the sun for long periods was considered bad, more atmospheric carcinogens than ever before, more flying. Also were still getting the tail end of the generations who smoked.

I don't think it's a huge difference but it's making a difference.

I think we might see a reduction in cancer rates, particularly with skin and lung cancers after the baby boomers die off. Gen X was the first to start to take sun care (hats, sunscreen) and anti smoking messages seriously.

Are those able to reproduce?
I suppose my question is more aimed at animals
who are too young to reproduce rather than hebephilia.

Maybe the question is are hoomans the only animal that regard
sex's primary function as a secondary one, i.e. derive pleasure
from the act of sex, similar to your young dog engaging in serial leg shagging.

Watching car reviews, I wonder how the car cargo space volume is calulated,
and why litres are sometimes used even though
as any fule kno the litre isn't a base SI unit.

I would imagine it's supplied by the manufacturer and just quoted. I can't see Auto Express messing around with airbags & similar.

And if you give the volume in cubic metres, 1) it will seem tiny, and 2) very few people will understand it.

Surely they just baffle it and fill it with water then measure how many litres come out when they drill through the floor ?

Ping pong balls.

It's measured using 1-litre 'ISO blocks' that are actually more like slabs than cubes, 20cm x 10cm x 5cm. These are stacked (usually virtually) and the total number of blocks that fit equals the number of litres. Like Tetris, there's an art to fitting the most in possible. It's not a wet volume.

ISO3832 sets out the method. So it is very comparable between cars and manufacturers as everyone follows a known process. What is surprising is some of the caveats, e.g. parcel shelf in place (estates suffer here) and including the footwell volume for row 2 seats down.

Lots of really interesting medical stuff

Wow - thanks for this - really appreciated and equally as interesting!

This is one of the things I love about PH - one can post some of the most obscure questions and another PH'er with genuine expertise in the subject will respond with a very detailed, but also understandable answer.

Many thanks!

Brilliant isn't it. We could probably get a step by step guide heart surgery!

Put it on youtube & someone, somewhere in the world will try it at home.

Theoretically the FM, AM and LW will be closest to the correct time, assuming all other things being equal (eg. FM, AM, LW and DAB transmitters all receiving the same signal at the same time).

In my house the "nearest real time" to "farthest from real time" order is :

Analogue Radio
Radio via Sky satellite
Radio via Freesat
DAB
Computer / internet

???

In my house the computer is easily the "nearest to real time". Timekeeping with ntp is probably about as close as anyone needs outside of some specialised fields.

Analogue radio is next followed by TV and the farthest being DAB.
The current time is...

You're not reading the question / understanding the context.

We're not talking about NTP or how accurate a computer is, we're talking about listening to pips on a radio programme.

When I listen to a radio programme stream via computer, it's easily the most "behind" of all of the above.

Yes I am and do. When I hear the pips on a DAB radio compared to the time on the computer or phone it (the radio) is usually behind. That would not matter whether I was listening to the "radio" on DAB or a streaming service on the computer. The computer or phone would be more accurate.

No, you're not comprehending what is being asked and what the answers are saying.

The question was about propogation delay when hearing pips on a radio programme.

I responded regarding what I hear in my house.

Out of: listening to a radio programme on my analogue radio, listening to a radio programme on my DAB radio, listening to a radio programme on my Sky box or listening to a radio programme on my computer, the stream on my computer is most behind.

Having a geek fest about NTP is bugger all to do with the question that was asked or my answer which you took issue with. Effectively which ever one your hear the pips on first is the most accurate. In my house, that's not the computer.

⚖️ The Bureau International des Poids et Mesures (BIPM) in Paris is the warden of the official international time. The Coordinated Universal Time #UTC is defined by averaging the signals provided by more than 450 atomic clocks in 65 countries. The operation is lengthy and we only know the exact time ...of last month!
 
〰️Time had been previously defined by the Earth movement and hence by astronomical observations. The use of a universal phenomenon – the vibration of atoms – since 1967 was in effect “a sea change”, says patrizia tavella, director of the BIPM’s Time Department.


So the closer you are to Paris the more accurate the time

They still haven't got over it being called Greenwich Mean Time.

UTC is so-called solely to appease the French

It's a globally agreed time datum.

It literally does not matter what we call it.

We have agreed a datum for time. We should call it "internationally Agreed Datum Time Even Though We Don't Like It"

Or "Whatever Time"


Wikepedia says: "The official abbreviation for Coordinated Universal Time is UTC. This abbreviation comes as a result of the International Telecommunication Union and the International Astronomical Union wanting to use the same abbreviation in all languages.[4] The compromise that emerged was UTC,[5] which conforms to the pattern for the abbreviations of the variants of Universal Time (UT0, UT1, UT2, UT1R, etc.)."

I do NotParkrun with the Director of BIPM on saturday mornings. A very nice Brit

In the film Minority Report (which I'venever seen), do they deal with the fact that if you prevent a crime before it's happened, you wouldn't have been able to predict it because it won't have been going to happen?

Kind of.

You should watch it. Good film. Mostly.

He can't see it because they haven't made it yet.

Depends on your understanding of space time.

There is only so much freshwater on the planet so how many times has the water in my cup of tea gone through a person before it ended up in my cup of tea?

Apparently water from the tap in London has been drunk at least seven times before.

Squeezed out of a turd by Thames Water, bottled water is looking like a necessity these days.

Where do you think the water that is bottled has been previously?

I was hoping it had been filtered through the rocks of Derbyshire or wherever rather than a Thames Water filtration plant.
