New Theories / Re: What's the unit of Torque?

« on: Yesterday at 14:15:27 »

"without rotation torque must be zero"? Not according to anyone who has tried to shift a frozen bolt. Anyway this has degenerated into another pointless hopeless argument bedevilled by utter confusion and i'm out.

You are confusing force and motion.

As others and I have repeatedly said torque can exist without rotation, therefore the angle is not an intrinsic component of torque- the angle comes into play when rotation has occurred and the energy expended can be calculated. You will not find a single reference that claims the angle is a component of torque and I think you are being deliberately argumentative for argument's sake. PS: in your example on #226 you state that the "torque is the same, ie  1joule/radian". This is wrong as it gives the energy per radian. Torque does not have the dimensions of energy.

If there is nothing, as you suggest, then your theories/hypotheses/conjectures do not exist.

Physics, Astronomy & Cosmology / Re: What Was The Speed Of Inflation ?

« on: 07/02/2025 20:53:25 »

Inflation is generally caused by bad monetary policy, the Weimar republic being an excellent example for study (SORRY!!). That is an interesting question ewe have posed and I don't know the answer. If one could imagine the leading edge of the expansion then it is difficult to determine it's speed as there is nothing at all, not even space beyond it and the material/space behind it is also expanding rapidly- without some reference point from which to measure the speed it is a difficult to state the speed. In all likelihood there is no leading edge as this a concept associated with the boundary between two volumes and in this case there is only one volume. It is difficult to conceive an expansion into nothing. These are my muddled thoughts on the matter, I'm sure there will be some better answers.

I agree with Alan. The cold water(kitchen) in my house is the only fresh water, all other water comes from an open storage tank in the attic. In one of my employments a dead pigeon was found floating in the attic storage tank.

We know what a rad is, I used the term because you were using it. There is no angle in torque.

A linear force may or may not produce motion- even if it does not produce motion the force is still present. Similarly a torque may or may not produce rotation and in the absence of rotation the torque is still present. In the absence of rotation what possible meaning or application is there for the rad? If torque produces rotation one can calculate the energy expended by the torque over the rotation angle but this is the only time the rotated angle has significance and it does arise in specifying the torque.

Question of the Week / Re: QotW - 25.02.14 - If fire needs oxygen to burn, how does the sun stay burning?

« on: 07/02/2025 11:45:30 »

What powers the sun is not combustion but nuclear fusion. If it was combustion the total life of the sun would probably be measured in the thousands of years.

General Science / Re: Oxygen levels In A packed Train. Is There Always Enough ?

« on: 07/02/2025 09:57:41 »

Even in an apparently sealed container like the tube there would be many areas of leakage allowing air in and out and the body heat of so many sheep would create convection. Probably not sufficient without additional ventilation but it would enable a breathable o2/co2 ratio for quite some time.

To expand on what I have already said I suggest looking up "mutaflor", a probiotic that consists of e. coli. Allegedly good for health in common with other probiotics, this on has been produced for ~100 years. E. coli or the colon bacillus as it is sometimes called gets it's name from the fact that it is very common in the healthy colon.

Not all e. coli are harmful. Some have picked up genes for toxin production from other bacteria- one particularly nasty example is where the e. coli picked up the dysentery toxin from shigella bacteria. Toxin producing e. coli can cause a range of illnesses including fatal conditions.

Chemistry / Re: What is the most and least metallic metals?

« on: 03/02/2025 21:11:27 »

Indeed there are. Several elements have both metallic and non metallic allotropes, such as arsenic, antimony and selenium. Tin is normally considered a metal but it can also exist as a non metal. Hydrogen under enormous pressure has a metallic allotrope and I think phosphorus, a non metal can exhibit a metallic form but I am far from certain on that score.  PS: I just looked at the periodic table and it did not include selenium as a metalloid and instead listed tellurium. One I missed was silicon but also included is germanium which I would have thought to be a metal.
