Okay, if I want to solve 5 x 7, I can stop doing multiplication and use non-multiplication to get an answer (0) and then claim that is the answer to the original multiplication equation (5 x 7 = 0). That's no different than what you are doing. It's crazy. It's stupid. It's wrong.

Claiming that not doing division is the same as doing division is actually objectively stupid.

You are wrong ., the relativistic mass doesn't depend on its energy.

What equation says that?

you can't use what you want

however if you stopped using multiplication it just means you are not using it , it doesn't imply you are using something else.

4 apples are to be divided between 0 people, the result is zero apples will be given to zero people , since zero is a number.

In fact it appears to be undefined.

What does it mean when we have empty bucket and we want to take three apples out of this bucket ?

Quote from: Yahya A.Sharif on 27/08/2019 13:23:264 apples are to be divided between 0 people, the result is zero apples will be given to zero people , since zero is a number.Actually, you would be giving four apples to zero people.

if you follow your own logic, this should mean that 0 - 3 = 0, since you end up with zero apples if you literally try to take three apples out of an empty bucket.

zero in reality and the natural world means the absence of things , zero people , zero buses, etc, if we have 4 people who left a room , then in this room we have zero people, if we have zero people in the room then we won't give them anything because they are absent , even if you have the the 4 applesSo is it the four apples you want to give, or 0 people will be given? they are the same , you have 2 people you want to give them 4 apples"4/2" or you have 4 apples you want to give to two people, if you think this is not the same then you have problem in your language .

You can't use my own logic to prove me wrong

my logic is my logic I'm the only one who is responsible of its results

You have to learn basic logic.

and they have nothing to do with division

but I gave them specific values, that satisfy physics equations

If they have nothing to do with division then they can't be the answer to a division problem.

The expression 0 - 3 = - 3has no meaning in words

They are undefined so they are already not solving division problem

In fact 0-3 appears to be undefined.

E=mc^2 is not the true equation for photons

photon is massles if m=0 E will equal zero, , but photon has energy

Quote from: Yahya A.Sharif on 28/08/2019 07:59:19E=mc^2 is not the true equation for photonsMass and energy are equivalent, so it has to work for photons just as much as any other particle.

we have a bucket with zero apples inside it, we want to take 3 apples . what is the number of apples we will take out? this is obviously undefined,

E=mc² your equation for photon's contained energy"

Kinetic energy of a photon equals its contained energy:If we use what you are talking about :K.E=E=mc²mc²=mc²/1-v²/c² - mc²While v approaches c the left hand side of the equation will approach infinity:So it will be :mc²=∞-mc² , what you are talking about is wrong,

the alternative equation is E=hf I mentioned in my previous post.

How this appears defined to you? we have a bucket with zero apples inside it, we want to take 3 apples . what is the number of apples we will take out? this is obviously undefined, only if you do not accept obvious things in order to prove you are right , in fact this says that we cant do subtracting , but it has a number, just like my example of 4/0 which appears to be undefined but it has a number
