New Theories / Re: Jano's relativity denials
« Last post by Jaaanosik on Today at 14:49:28 »So what's your point?The most noble inclination of Human Nature is pursuit of truth.
That itch to find out how things work.
Our discussion here is a manifestation of our Human Nature.
There is a reality on one side and then there is our worldview/understanding of the reality.
How accurate is our worldview?
Personally I go with two levels: hypothesis/concept and theory.
When hypothesis matures and experiments support the hypothesis then it evolves to theory.
Many more details surround a hypothesis, for example assumptions, postulates, principles...
If a mistake was made here then a theory built on it will fall.
No questions from anybody regarding my thought experiment so I'll move to conservation of linear momentum analysis.

Physiology & Medicine / How Do You Classify Corn?
« Last post by Jimbee on Today at 12:51:42 »Is corn really a vegetable? Where I live, the US, it is classified as one. (We also call it Indian corn. And in the rest of the world they call it Maize.) It is also cooked and prepared as one.
How do they decide how a food product is classified? I am talking about from a nutritional perspective, BTW.

New Theories / Re: Could quantum mechanics be wrong?
« Last post by alancalverd on Today at 12:31:24 »That's the first step of any scientific research. Without any research gap, there will be no job for researchers.Research is the penultimate tactic for solving a problem, prayer being the last. Career researchers are not parasites like priests, but scavengers among the debris of ignorance.
Almost all worthwhile science derives from an unexpected observation. Have you made one?

Physics, Astronomy & Cosmology / Re: why do a lot of people confuse between interference and diffraction?
« Last post by alancalverd on Today at 12:20:38 »One of the problems with physics is that lay persons and journalists don't understand the difference between strength, power, force and energy, so they go on to talk nonsense about a zero-carbon economy and other such drivel. The statement that an aperture can cast a shadow is worthy of a politician, not a scientist.

New Theories / Re: Could quantum mechanics be wrong?
« Last post by hamdani yusuf on Today at 10:59:34 »There's also the issue of product stability. A bond between a hydrogen atom and an oxygen atom (bond order 1.0) is far stronger than one between a helium atom and an oxygen atom (bond order 0.5). It's easy enough to know the reason for this if you look into the literature.
I asked Gemini about bond order.
Quote
The concept of bond order specifically applies to covalent bonds between two atoms of the same element. In the case of a hydrogen atom and an oxygen atom, they form a polar covalent bond.
Here's a breakdown:
Bond Order: This refers to the average number of bonding electron pairs shared between two atoms. It typically applies to multiple covalent bonds between similar atoms, like in O2 (oxygen molecule) or N2 (nitrogen molecule).
Polar Covalent Bond: This type of bond arises due to unequal sharing of electrons between atoms with different electronegativity values. Oxygen is more electronegative than hydrogen, so it attracts the shared electrons more towards itself, resulting in a partial negative charge on oxygen and a partial positive charge on hydrogen.
Therefore, instead of a specific bond order, the bond between hydrogen and oxygen is described as a polar covalent bond.

New Theories / Re: How does Hamdani explain the twins paradox?
« Last post by hamdani yusuf on Today at 10:49:36 »In the explanation by Henry's Minutephysics and Mahesh' Floatinghead Physics, acceleration of the observed clocks don't cause any time jump. Time jumps only occur when the observer is looking at far away clock while changing velocity.You missed the fact that the Earth clock is inertial between the two events of the 'jump' and the traveling clock is not, so its worldline is half the temporal length that it would have had had it been inertial between its two events.Where does the number "half" come from?
We know we are having a knowledge gap when we have a quantitative answer without knowing where it comes from.

« Last post by hamdani yusuf on Today at 10:39:55 »Then why doesn't it say so?
Perhaps it assumes that the statement is simple enough for laypersons to understand what it means.
