Discussion Overview

The discussion revolves around the Pythagorean theorem and its application in a proposed notation involving the terms Ab, Bc, and Ac. Participants explore the validity of expressing the theorem in different forms and the implications of these expressions, particularly in relation to the speed of light.

Discussion Character

  • Debate/contested
  • Mathematical reasoning
  • Conceptual clarification

Main Points Raised

  • Some participants question the notation used, particularly the equivalence of Ab/Ab + Bc/Bc to Ac/Ac.
  • Others argue that Ab/Ab equals 1, while Ab2/Ab equals Ab, leading to confusion about the validity of the proposed expressions.
  • A participant attempts to prove that the speed of light should be zero by relating it to the Pythagorean theorem, suggesting that Ab and Bc must be equal for this to hold true.
  • Some participants express skepticism about the mathematical reasoning presented, indicating that the expressions do not hold under standard arithmetic rules.
  • There are claims that the Pythagorean theorem does not relate to the speed of light, with some participants emphasizing the need for a proper understanding of algebra before tackling more complex theories.
  • Participants discuss the implications of dividing by zero and the misuse of arithmetic operators in the context of the proposed equations.
  • Several comments reflect frustration over perceived misunderstandings of basic mathematical concepts and the implications of the proposed ideas.

Areas of Agreement / Disagreement

There is no consensus on the validity of the proposed notation or the relationship between the Pythagorean theorem and the speed of light. Multiple competing views remain, with significant disagreement on the mathematical reasoning and interpretations presented.

Contextual Notes

Participants highlight limitations in understanding basic arithmetic and algebra, as well as the potential misuse of mathematical symbols and concepts. The discussion also touches on the philosophical implications of time and space in relation to the proposed equations.

Ab2 + Bc2 = Ac2

Can you also write this like..

Ab/Ab + Bc/Bc = Ac/Ac..?
 
Physics news on Phys.org
What does your notation mean??
 
The question is of this notation is more our less the same.
If Ab2 and Bc2 have the same value...
Ab X Ab = Ab2 so Ab2/Ab =Ab
 
err, no since presumably
Ab/Ab + Bc/Bc = Ac/Ac

is 1+1=1
 
0+0=0, mathematics don't lie...

..mathematics don't lie...

But a string of symbols is not necessarily mathematics..
 
so Ab/Ab =0 does it...? oh...
 
Ab/Ab=1
AbxAb=Ab2
Ab2/Ab=Ab

Ab2/Ab + Bc2/Bc = Ac2/Ac

Example..

2x2/2 + 2x2/2 = Ac2/Ac...
 
do you have a point (other than you don't seem to know any maths) or are you just trolling?

I try to proof that lightspeed should be zero.
If Ab ( time) and Bc ( distance ) are always the same for lightspeed.
Every second 300.000 km more, than is this not possible.
Only if time and distance are always the same, the speed of light is zero.
I think I can proof this with phytagoras.

If Ab2 + Bc2 = Ac2 you also coult write this down as
Ab/Ab + Bc/Bc = Ac/Ac.

This is only correct if the speed of light is zero. I think i have a good point here. It's hard to explain.

I'm not too sure of the notation you are using, so I couldn't really help you out. I think this post belongs in theory development from the looks of it.

Uh... no...

a2 + b2 = c2

\frac{a^2}{c}+\frac{b^2}{c}=c

\frac{a}{c} + \frac{b^2}{c*a}=\frac{c}{a}

\frac{a}{c*b} + \frac{b}{c*a}=\frac{c}{a*b}

Seriously... you need to get through algebra before you go after general relativity.

I still don't have an answer if Ab2/Ab is the same as AbxAb.
And why Ab2 + Bc2 = Ac2 is not the same as Ab/Ab + Bc/Bc = Ac/Ac
I know that this formula only is correct if Ab and Bc are zero. But I think a got some point here.

Are you kidding? I just did it step by step for you.

A*A=A^2

A^2/A = A

A*A != A^2/A

And why Ab2 + Bc2 = Ac2 is not the same as Ab/Ab + Bc/Bc = Ac/Ac

See line by line derivation above.

But I think a got some point here.

DNFTT enigma...

Are you asking if "the product of a number and itself divided by that number" is equal to "the product of a number and itself"? No, unless that number is one.

The pythagorean theorem relates the lengths of the legs of a right triangle to the length of the hypotenuse. It doesn't say anything about the speed of light.

Since you're dividing by zero, it's not true then either.

You're such a killjoy. :wink:

Correct 1+1=1...

If you do 1 km + 1 sec you got 1 km/sec
Its correct that 1+1=2 but wat does 2 mean in this example...

Thank you for your concern, Math is Hard, I thought I had pulled through, but then I didn't close my eyes fast enough to overlook rudeonline's last post..

I certainly would not, but isn't that what YOU are saying?

If you do 1 km + 1 sec you got 1 km/sec

Looks like we need to start with the basics for you. Notice that in the expression "1 km/sec" you use a "/" in grade school we are taught that this is a symbol of division, not addition. Why do you show addition on one side of the equal sign and division on the other? Are you familiar with the meaning of equality? Should not the same quantity be on both sides?

No I would not say 4 people + 1 car = 4 people/car but I would say that:
4 people/ 1 car = 4 people/car

or 4 people/ 2 car = 2 people/car

So now that you have had a lesson in grade school arithmetic perhaps you can take your ideas back to the drawing board and attempt to apply correct arithmetic to them.

Ab is a car
Bc is a person
Ac is persons per car.

1 person + 1 car = 1 person per car ( 1 P/c)

This is why Ab/Ab + Bc/Bc = Ac/Ac
1/1 + 1/1 = 1/1
car person = person/car

Now, if lightspeed is a constant one Ab en Bc are the same. Each second the distance is the same. If light would go faster our slower Ab our Bc would have a different value an be more as 1.

Did you bother reading my last post? Try again... If you cannot do simple arithmetic how can you hope to comprehend algebra, which is clearly beyond your skill set.
 
  • #26
Wat is frong with my post?
 
  • #27
Er... How about misuse of arithmetric operators?
 
  • #28
I try to explain that time and space are the same, nobody seems to want to see that. Not really a problem for me, just a pitty for scientists. But anyway, I will not be the first person witch was ignored till people became more clever.

I'm laughing pretty hard at this point. :smile: :smile: :smile: :smile:

According to you: 1+2 = 1/2
or: 3 = 0.5

Quick! Alert the media! Math is wrong! We have to get the word out...




Oh, and your obvious misuse of units should be pointed out. One second CAN'T BE EQUAL TO A METER. A meter is NOT time. That's like saying "I have enough weight here to power a small lamp!"

You've ever moved a meter wihout using time?
