Physiology & Medicine / Re: Can a fungus be a parasite and what distinguishes the two?

« on: Yesterday at 23:44:36 »

Hi.

   I'm not sure what the question was about but the last post is worrying.

I don't want to be alive any more

  That seems like something you should be discussing with a professional as soon as possible and not just some online forum where none of us (I think) are medical professionals.

Best Wishes.

There are a number of medical professionals here, but it is impossible (and would be wrong) to try and make a diagnosis without performing a number of tests which can only be done in a clinic.

This forum is clearly not helping the OP, and may be harming his mental state, we can only reiterate the advice given by ES. Seek professional help and keep escalating the problems until you get a diagnosis.

That CAN'T be true! / Re: I have a question too long to fit here, I apologize.

« on: 17/06/2022 14:28:51 »

... but all signs seem to point to me being correct.

Actually, non of the signs point to you being correct.

Calendar systems evolved around annual seasons and vary around the world, it’s easy to convert between them and they have no effect on Einstein’s theories.
Here we talk about pseudoscience, which is often the stringing together of scientific sounding words that has no scientific content or meaning. Vortex maths is often referred to as pseudomaths for similar reasons and will be of no use in determining anything scientific.

Overall, you have not given sufficient detail on your calculations for us to make a final judgement, but the above points are a good indicator.

Are you mad? Well, there are many forms of madness. We often get posters who feel they have overturned Einstein’s theory, or quantum mechanics, or who think the earth is flat, or that man has never landed on the moon. I would suggest they are delusional.

New Theories / Re: An essay in futility, too long to read :)

« on: 13/06/2022 05:17:22 »

Quite interesting, and with a twist.

" A 2007 study found that for every 1C increase in night-time temperature there is a staggering 6% drop in wheat yields – a steeper decline than hotter days. The climate crisis is triggering record-breaking day temperatures, but night temperatures are increasing significantly faster."

Another twist towards the end of the Roman era in Britain:
“ About AD 400, there was a shift to wetter, colder weather in Britain, a deterioration that intensified after AD 450. By the late Roman period, there may have been as much as a 10% increase in rainfall. Together with deforestation and expanded agriculture and grazing, heavier rains would have aggravated soil erosion and flooding. Soil would be leached of its nutrients and fertility; and heaths and bogs would have claimed arable soil and lessened productivity.

Annual average temperature also dropped during this time, perhaps as much as 2.5 degrees F (1.5° C). This would have lowered the elevation at which grains could grow by 650 feet and shortened the growing season by almost one whole month. Colder weather also would have reduced the hay crop and made it more difficult to sustain animals through the winter. Weakened animals, too, would have been more susceptible to disease.

Marginal land for agriculture would have become sub-marginal, and much of the highland zone, with its longer winters, heavier rainfall, and lower average temperature, no longer as productive. Shortfalls in the north, in turn, would likely have increased demand for exportation of grains and increased taxation in the south.”

Physics, Astronomy & Cosmology / Re: How would we know whether space,time or spacetime were continuous or discrete?

« on: 12/06/2022 08:48:06 »

However, there's still a minor issue.   Start with a rod at rest in your lab frame and give it exactly the minimum length, L, which your x-axis supports.   Now get that rod moving along the x-axis relative to your lab frame.   Do you see the rod contracted and having less length in your lab frame?   
     Can it have less than the minimum grain of length that is available in your lab frame?

     The only way to get around this is to assume the minmum length that you measure or observe in your lab frame, is only a minimum length for objects that are also at rest in your lab frame.   That's OK,  that's consistent  - but it means that your idea of a minumum length in the lab frame isn't  my (or most other people's) idea of a minimum length existing.   Some objects do have lengths smaller than your idea of the minimum length (all those which are not at rest in your frame can have smaller lengths).

Best Wishes.

Ok, I understand that, but my main concern was the statement that this violates the assumption that the laws of physics are the same in all frames.
My contention is that the laws of physics are the same because using the physical laws of relativity we can understand what is happening. Two people in two labs will measure locally (by which I mean they are colocated, at rest and at the same gravitational potential as the property being measured) the minimum length to be the same - proper length. If someone in a lab moving relative to one of those labs tries to measure that lab’s minimum distance, not only will that distance be contracted (as you rightly say) but the measuring apparatus will also be contracted and when you use relativity to work out what is happening you find they all measured the same distance. All consistent. What would shock me would be if the proper length changed.
We get the same problem when measuring the wavelength of a Cesium clock from a different gravitational potential, but we do understand why and it’s consistent with the laws of physics.

I agree that this does not align with most peoples’ view of a minimum length, but relativity doesn’t align with most peoples’ view of what we should observe

You will no doubt deny this, but it is what has been written. I will screenshot the thread to stop you altering it to suit your needs as posts have been altered before.

I have never altered a thread to suit my needs, nor those of anyone else.
Think carefully before making false accusations.

My point stands: don’t accuse people of spamming when they are trying to discuss an issue, address the issue directly.

« on: 11/06/2022 23:51:25 »

Well Colin pop the keys in the ignition and tootle the earth around. …. or perhaps a giant robotic geisha could shade us with her super umbrella.

Give me a lever large enough …..
However, your second suggestion is closer to the mark. The proposal was that NASA put reflective chaff in orbit to reduce the amount of sunlight reaching earth.



If you wish to be so dilute global warming is like  a fridge we only have to remove energy from the earth and well cure it, so I will just hook it up to a refrigerant compressor,Basically under such loose constraints it is energy and we need to have less energy. But a 4 year old can tell you that.

Doesn’t make sense, not sure what you are saying, but it won’t work unless the other end of the fridge is off earth.



All materials will warm at like rate, increacing as the global temperature increace, proportionally to their current temperature, they will reach equilibrium due to emissivity. . That is why heat capacity is important and nothing like a car in the sun.  The thermo dynamics of large omplex systems are different to those of small ones.

no one said otherwise, but non of that negates what kryptid was saying



What sort of sense does this make?

Alancalverd's answer wasn't nonsense, it was the truth. If the air, land and water are getting warmer, then they are storing more thermal energy than they were before. Obviously, the energy that causes a material to heat up is stored in the material itself. I don't know how any other answer would make sense.

It makes perfect sense.
Obviously there are other ways of storing energy in a material other than thermal capacity  eg in chemical reactions such as photosynthesis to wood etc

Physics, Astronomy & Cosmology / Re: How would we know whether space,time or spacetime were continuous or discrete?

« on: 11/06/2022 23:44:03 »

@Colin2B    I'm not certain what you're trying to say there.   

Sorry, I was in too much of a hurry to expand.
The laws of physics are the same in all inertial frames yes, but not necessarily between frames. Take conservation of energy, true within any frame but not between frames, we need to take into account of relativity.
So you say “ If you decide that the minimum distance or granularity of space is a "law of Physics", it should be the same in all inertial frames of reference.”
What I would say is yes, assume there is a minimum distance, but don’t assume that specific distance is the same when measured from any other frame.
How are you making the measurements? In your lab frame at rest relative to what you are measuring, you are using one set of clocks and rulers, which you cannot apply to another lab moving relative to you unless you convert using relatively. However, that other lab making local measurements of their ‘at rest’ set up will get exactly the same results as you. So, the laws of physics are the same in all frames.

Of course I may have completely misunderstood what you were saying, so I’ll try to find time to read all the recent replies.

They should see that rod contracted, which means that in their reference frame there exists lengths that are less than L - the minimum length that should exist.     So the minimum possible length is not consistent across all frames of reference,  which contradicts the idea that the laws of physics are the same in every inertial reference frame.

If you were talking of proper length I would agree, but the laws of physics include relativity and measurements from a non-local frame such as you describe will show contraction. Relativity allows us to understand that the measurements are consistent across all frames.

Just Chat! / To answer a question from Pseudoscience-is-malarkey

« on: 11/06/2022 12:58:47 »

I notice one of the other moderators has removed your post, so I’ll answer your question here

Why do we have to be subjected to such juvenile garbage on a science site???

It's the "Just Chat" section of a science sight. Anything goes, as the description pretty much states.

No, anything does not go.
We give more leeway in this section than others so it doesn’t need to be science. However, it does need to be family friendly.

Also, I do for some levity.

Levity is one thing, but you often use this section for posts in bad taste and/or of a sexual or crude nature. That’s not what this section (or any other) is for.

NASA already have versions of this on their ideas list.

I thought I had posted these in a previous discussion with @geordief but it looks as though the post was truncated without giving the full answer.
I can vouch for the authenticity of these simulations having been involved on proof checking some of the original work, but funding has been diverted to other projects rather than extending to cover other scenarios.

Physics, Astronomy & Cosmology / Re: Does The Universe Spin ?

« on: 06/06/2022 09:06:32 »

It doesn't look like anyone has mentioned   Mach's Principle 

I don’t think anyone has ever pinned down Mach’s principle to a complete theory, although I do find Lense–Thirring interesting when applied to an outer shell of mass.
Interesting thought, if we can’t see beyond the visible limit how much would any mass out there affect our perception of rotation if it is spinning relative to the bit we can see. Mach thought it would.

I think the universe  is only a "thing" if you can point to it  some way.
I can't see how we could do that even in principle.

Scientific and mathematical terms are usually well defined for good reasons; general language is often more open to interpretation and misunderstanding as you say. ‘Thing’ is pretty vague and could cover an idea:
Merriam-Webster for eg:
1: an object or entity not precisely designated or capable of being designated
2a: an inanimate object distinguished from a living being
b: a separate and distinct individual quality, fact, idea, or usually entity
c: the concrete entity as distinguished from its appearances
d: a spatial entity

Edit: by the way, I agree with @Halc that it doesn’t make sense to say the universe is spinning. If, say, we define the universe ‘thing’ as everything that exists, then what could it spin relative to?
Getting too close to philosophy for my liking
