Farting in the lift is wrong on many levels.

New Theories / Re: Photo of subtle body, photo of soul, photo of astral body
« on: 27/11/2023 23:40:57 »If the lower subtle body could be observed in the ultraviolet spectrum, then the higher subtle body should logically be observable in the X-ray spectrumThere is nothing "logical" about that.

Two things.
Evolution has about a billion year head start on us and
there's no market because the machine would have to be cheaper to build than a dog.

Question of the Week / Re: QotW - 23.11.24 What can seeds to for our health?
« on: 23/11/2023 19:39:09 »
If you are careless when eating apples you should be glad that the pips go through unchanged.
If chewed they release cyanide- though not enough to do any harm.
Eating seeds is pretty much universal when you think about it; wheat, maize, rice and so on as well as pulses and nuts are essentially seeds.

General Science / Re: What happens when a superconductor is utilised in a circuit?
« on: 22/11/2023 18:30:48 »
One thing they do with superconductors is make electromagnets.
These often have large inductances.
Let's pick a number out of a hat and say it's 10 henries.
Imagine I connect a power supply to that coil and it has an output voltage of 10 volts.
Initially no current is flowing.
When I make the connection the inductance of the coil limits the rate of change of current.
The current will rise (from zero) initially at 1 amp per second.
After 10 seconds the current flowing will be 10 amps.
Imagine that I have things set up so that the coil is short circuited by a piece of "superconducting stuff" which is too warm to super-conduct.
Initially it makes no real difference. Some current flows in it but, if I'm clever, not much.
But when the current reaches 10 amps, I cool that short circuit down and it becomes a superconductor.
The power supply is short circuited and so it blows a fuse or trips out or whatever.
But the current of 10 amps continues to flow in the coil and through the link (which is now cold enough to be a superconductor).
Equivalently, you can make a switch out of superconductive stuff and close the loop with that.
Interestingly, (almost) all the modeling of inductors and capacitors that you see in high school text books assumes that they have zero resistance.
All the maths you saw was designed to work with superconductors :-)

Science Experiments / Re: How to demonstrate polarization of light?
« on: 21/11/2023 23:52:07 »
For what it's worth, the classical description of polarisation also explains the transmission through three polarisers.
It's not a very paradoxical paradox.

General Science / Re: What happens when a superconductor is utilised in a circuit?
« on: 21/11/2023 23:41:19 »This scenario will also involve a potential across the piece of superconducting wire which is obviously impossibleIt's allowed because it's the voltage across an inductor.
(which is proportional to the rate of change of current.)
And the R for calculating the time constant is the total resistance in the circuit.

The Environment / Re: The link between global warming and world population expansion.
« on: 20/11/2023 11:11:58 »True, but that was decades ago and it looks like both sides forgot about it.In doing so, it would have robbed the terrorists of their support.It must be remembered that the USA supplied weapons and intelligence to the Taliban when they were called Mujahadeen.
The guys fighting the USSR in 1980 were probably not the guys fighting in 2001.
But, when I said their support, I meant their local support from the folks living in Afghanistan.
Those people would be swayed by food better than bombs.

Israel has won the war in Gaza and Hamas need to surrender immediately.to protect their women and children.
Or
Hamas has won the war in Gaza and Israel need to surrender immediately.to protect their women and children.
It's impossible to tell.
"Those people that did not apply for citizenship would automatically become refugees"
A plan to deliberately create refugees is a bad plan, isn't it?
Here's a radical idea for you.
Israel withdraws from the land which they are occupying illegally and lets the Palestinian people live in their own land.
Those people can choose their own government.
Without the persecution, the people of Palestine will no longer feel any need to support terrorists like Hamas.
What do you see as the problem with that?
On a tangentially related note, when (post 9/11) the Americans decided to bomb Afghanistan, I thought it was a foolish move.
I figured it would be better if they dropped food.
Partly because food is cheaper than laser guided high explosives.
But mainly because it would have utterly undermined the Taliban claim that "The West Hates us and we are at war with them".
In doing so, it would have robbed the terrorists of their support.
I realise it's far too late but what do you think of that plan?

Correction. I reach IQ not 400 points, but 1600 points.
And you really should see a doctor about these delusions; urgently.

New Theories / Re: How do we measure the energy of a photon?
« on: 16/11/2023 23:41:47 »You need a course in logic.OK, You specified two things that can be central systems.
A black hole or a sun.
And you said that the central system explodes as a LFBOT.
Black holes don't explode; nor does the sun.
At best all you have done is say "someting went bang" which is true, but uninformative.

It's a matter of definition. If you stand on the bathroom scales the answer will be nearly* "yes".
If we find a way to discount the mass of your stomach contents from the mass of "you" then no.
*
Not quite constant, because you lose mass by breathing.
You lose water and the CO2 you exhale is heavier than the O2 which you took in.

Just Chat! / Re: Does every town in the UK have a football club?
« on: 14/11/2023 10:26:17 »
OK.
I searched for all the towns- and there's a lot.
https://www.townscountiespostcodes.co.uk/towns-in-uk/
So I picked Merseyside because I know it's an area that plays football.
And I looked for the first town (alphabetically); Ainsdale.
And looked for a club and found Southport and Ainsdale amateurs.
Does that count as Ainsdale having a club?
