something with a bit of comedy

Chemistry, Biology and Physics.

It must be useful there and then, nuclear physics just isn't going to be worthwhile. Depending on the constraints, material properties, material extraction and material production. If that's one as Materials Science then medicine and agriculture. Depends really whether you take this science as common knowledge.

General Science / Re: What's 0^0 ?

« on: 24/10/2024 21:23:23 »

If you think logically 2x0 is a non function, this sort of sum can cause all sorts of problems.  Even though the sum above does infact give the answer of zero it is not arrived at in the conventional sense of 2x0, that is 2x0=0, it is a non function that gives an answer of zero through its non function status. Zero being zero is neither positive nor negative. Therefore a non functon zero from 0^0 must be true.

What experiments/theory led to the conclusion that light impinging on a moving object at any arbitrary speed( <c) would always arrive at c?

General Science / Re: How Do We Know The Temp Of Absolute Zero If We Can never Reach It ?

« on: 15/05/2024 00:36:35 »

If temperature is a measure of movement over time it creates a problem. If you take an instant, a photographic moment that is impossible to have, all matter would essentially be not moving and therefore absolute zero, coversley any measure over time is open to infinity.

Just Chat! / Re: What is the difference between Beer, Lager and Ale?

« on: 26/02/2024 23:42:31 »

From what little I know, Lager is cold brewed, with most of the fermentation going on at the bottom of the batch. Ale is the other way around: warmer and top fermenting.

Yep, the different yeast ES hypothesised, i think that is the biggest difference in the brewers world, followed closley by wheat beer.

Ale is apparently hopless, as in without hops.

I read it.

How is this making explanation of the low temperature state? I am assuming that the free electron is loosed at low temperature?

I just wish the cookies think would, in the most harsh terms, piss off. The amount of time i spend clicking on cookies buttons is horriffic.  As far as i am concerned the internet is outside the house. Any advertising, any danger, scams, pornography, violence, weapons, social media should be there and if i dont want it i dont go on the sites,  like twitter.

I regularly search for "naked" when i am trying to find  this site in my browser history,  but it usually brings up a film with Marlon Waynes. I havnt got big boy internet so anything with the word gun knife etc is filtered automatically. It can get annoying though.

Physiology & Medicine / Re: Washing Your Hands After You Pet Your Cat.

« on: 16/02/2024 19:35:41 »

Cats tend to be cleaner than dogs.

Depends on your definition of clean. They certainly spend more time licking themselves, and in more places, than dogs, but anyone allergic to cat saliva (and a surprisingly large number of people are) wouldn't agree with the proposition.

I have never seen a cat drag its anus across the parlour carpet alan.

Edit.

Yes wash hands, also kitchen surfaces.

Anyway, more on brain worms

If the topic was about brain worms why didn't you name the topic brain worms?  The answer to the question in the title can be found in reply #1.

It aint my thread!

Physiology & Medicine / Re: Why Can You Pinch Your Elbow And Feel NO pain ?

« on: 23/01/2024 16:50:12 »

My guess is that  the nerve endings in the elbow by continually pressing the skin against the bone either by leaning or by streching the skin through flexing are numb.

That CAN'T be true! / Re: What is "four times less"?

« on: 08/12/2023 13:21:21 »

Four times, less scrubbing. Scrubbing required by Brand Y ? 4= the ammount of scrubbing you will have to do with Brand X minus the Scrubbing required by Brand Y ----->  5(scrubbing brand y) = scrubbing brand X.


But it could also be

Scrubbing required by Brand X?4= the ammount of scrubbing you will have to do with Brand Y.

As for a proof that would satisfy a power engineer, it is in the first lecture of Nuclear Reactors 101. But that was nearly 60 years ago so I won't attempt to recall it now.

They do the practical in the lecture, how exiting.

Vain morons with idealistic outlooks who have no idea how to do anything. You have the king of the UK who being terribly rich amongst politicians from Eaton Cambridge (<----- !) and harvard who are ex bankers speaking of their dreamy plans with no idea how to implement said plans and no need whatsoever to do so, they remind me of the just stop oit protestors. Heat pumps and solar panels are not an idea for the UK, if you want your own renewable energy source here, invest in a wind turbine.

These people cannot even make the economy function, so making a switch to renewable energy is going to end in failure.

Physics, Astronomy & Cosmology / Re: QM puzzle: Is a measurement being made in the 2 slit experiement all the time?

« on: 02/12/2023 09:50:31 »

The experiment is repeatable with atoms and even molecules.

https://en.m.wikipedia.org/wiki/Double-slit_experiment#Variations_of_the_experiment

This would suggest that it isn't necessarily reliant on reading the results, but it does however not rule out any interference from the locale in the form of gravitational waves, electro magnetic influence or what effect the screen may have on the results.
