1. ### A Question about Entropy

You may feel annoyed, but... Sometimes, rigorous tends to mean 'accepted'.
2. ### A Question about Entropy

Thanks everyone for their answers... A thing comes to my mind here... 'Everything is debatable'... Maybe this line is also debatable☺️☺️
3. ### A Question about Entropy

So, I ask further..... To my mind, if we come to know everything about all the particles at equilibrium (just suppose), we wouldn't call it disorder AT ALL. Then the entropy at equilibrium would be zero. So, it seems our 'inability' is translated as disorder... Hope, there is some sense in...
4. ### A Question about Entropy

If icing is to be spread on a cake and we do it in lumps (boundaries), it is disordered.. But, if we spread the icing evenly(uniformly), it is 'ordered'.....
5. ### A Question about Entropy

I think 99.999999% of people on this planet only acquire stuff along the way.... It's only a miniscule minority that ever says something new...
6. ### A Question about Entropy

OK. Fine. But, I have a problem regarding this. When the ice cube melts completely an equilibrium will be reached i.e a state of highest entropy will be reached. Isn't equilibrium itself a kind of 'ordered state' (a state where there is perfect balance). Why to call such a 'balanced'...
7. ### A Question about Entropy

Any experimental proof for this statement.
8. ### A Question about Entropy

Our universe is considered a closed system. Law says that the entropy of a closed system is bound to increase. Then how could living beings evolve when they are an extremely ordered system?
9. ### B What is the reason for the Emergence of properties?

Pressure of a gas is an emergent property. The notion of pressure is not attached to a single molecule/atom. Suppose, I keep on adding a molecule one by one in a jar. So, pressure (an emergent property) comes into existence over time.
10. ### B What is the reason for the Emergence of properties?

I am a nobody to coin any kind of definition.... It's just my curiosity that may be getting annoying for people here. I think emergence does not /should not mean the same numbers and same types of fundamental particles... It means /should mean the occurrence /creation of something/some...
11. ### B What is the reason for the Emergence of properties?

I have checked the standard definitions. These call turbulence, temperature, pressure Etc. as emergent properties. I am just a layman but I think I am also saying the same thing. I think 'something happening' to the quantum field is the 'fundamental' emergence. All other cases of emergence...
12. ### B What is the reason for the Emergence of properties?

I think these also would be called emergent properties because something has happened to the quantum field that was not there before.
13. ### B What is the reason for the Emergence of properties?

I have thought of an experiment (unless you rubbish it) Let's take a quantum field. There is no excitation in it (suppose). Then someone observes it and the excitation of the quantum field gets manifested in the form of an elementary particle. To my mind this is the experimental proof of...
14. ### B What is the reason for the Emergence of properties?

Thanks for a brilliant answer.... But in physics also we surely talk about emergent properties that are related to structure of atoms /molecules. And they ain't philosophical questions.
15. ### B What is the reason for the Emergence of properties?

I can't think of any such experiment. So, do you mean to say the answer is unknowable?
16. ### B What is the reason for the Emergence of properties?

Thanks everyone for judicious answers... What I wanted to ask is actually very laymanish... Suppose, I have a large structure through which I can move and so on. But when I go up and get a bird's eye view of the same structure, I get to see a pattern/shape which was not visible from the...
17. ### B What is the reason for the Emergence of properties?

Water molecule has different properties from either oxygen or hydrogen atom. My question is 'Are these properties of water molecules totally new or were these properties already lurking around in the oxygen and hydrogen atoms?' Thanks.
18. ### B Question about Curvature caused by Mass

Laymen are most certainly well versed in spacetime diagrams...
19. ### B Question about Curvature caused by Mass

I think quantum mechanics allows this, even if the probability is miniscule....
20. ### B Question about Curvature caused by Mass

I have kinda got the idea... Can you please elaborate more and that too in layman terms.
21. ### B Question about Curvature caused by Mass

A body is moving in deep space substantially away from others influences of gravitational force ( just assume). Suddenly, a big planet appears in It's vicinity. As per relativity it's not some force issuing forth from the planet that attracts the body towards itself. The body just keeps on...
22. ### B Effect of the Sun's Gravity on the Moon

Ok. I have deleted my post...I want to be cautious..
23. ### B Instantaneous Reactions

Do you want to say that there is nothing like 'instantaneous reaction'...
24. ### B Instantaneous Reactions

Thanks everybody for the answers... Actually, I think I was not able to express myself properly nor was able to provide a good example... I want to say that 'when there is/are sufficient cause(s), the effect is bound to happen necessarily... Isn't this instantaneous? For example in an...
25. ### B Instantaneous Reactions

Why don't you provide an exact definition of an instantaneous reaction..
26. ### B Instantaneous Reactions

Lol... I mean when an acid molecule reacts with a base molecule...
27. ### B Instantaneous Reactions

E.g. when an acid reacts with a base...
28. ### B Effect of the Sun's Gravity on the Moon

Thanks everybody...
29. ### B Instantaneous Reactions

Do instantaneous Reactions happen at infinite speed?
30. ### B Effect of the Sun's Gravity on the Moon

Then why is moon not ripped away from Earth...
