Excuse me Strange. But a,b,c aren't sides of triangle. They should be just derivatives from angles like factorial or something else. m2=m2 All is correct. I do make for equilateral triangle.

Area and perimeter.

Fatness of triangle=A/P2 A/P2=1/(a+b+c) We know that: When angles of triangle are 60,60.60 degrees then a=b=c=12/(3)1/2 When triangle angles are 45,45,90 then a=2 b=2 c=2*21/2 When angles are 30,30,120 then a=14 b=14 c=16*31/2 Can we make any actions(the actions should be the same for any triangle) with triangle angles to define a,b,c ?

Some features of a parabola Coordinates of the vertexThe x-coordinate at the vertex can be found by completing the square to put the equation in vertex form, or by differentiating the original equation, setting the resulting equal to zero (a critical point), and solving for . Both methods yield . Substituting this into the original equation yields https://en.wikipedia.org/wiki/Parabola a=3 not -3 y= -24 - (-6)2/(4 * 3)

I know exact definition of time. Time is quantity of nonsimultaneity between two events. Nonsimultaneity is change of ability of distance to transmit signal.

See Janus's post about Doppler effect:http://www.scienceforums.net/user/222-janus/?tab=reputation&app_tab=forums&type=received&st=30 " Now for light,traveling in a vacuum which does not require a medium and adjusting for Relativity, we use where v/c is the relative speed of source and receiver measured as a fraction of the speed of light and is positive when they are approaching each other. With this formula, it doesn't matter which(source or receiver), is considered to be moving."

I exactly know that an observer doesn't see contracted gap between simultaneously accelerated rockets. Therefore you can't deceive me. Once you have admitted with brag that you were breaking laws of USA. Therefore it's not surprising when you make crime in science.

I thought observer makes math of moving object relative to own frame.And when observer can't make the math then he/she isn't a scientist.

Then all is in own frame and nothing is contracted. I don't understand such science .

If you don't understand relativity then you should consider usual analogue. For example you push or pull very long and hot metal rod. Cold wind cools the rod. Then force of length contraction of the rod increases force of acceleration of tail of the rod and reduces force of acceleration of head of the rod. Do you deny even this?

Net force can't simultaneously accelerate and contract all parts of object even mathematically. Object at v has contracted distance of own forces balance. Therefore preservation of distance causes force of reaction against the distance.We can call the force by force of length contraction.

net force=2F for tail +F for middle + 0 for head at start of motion =F for tail+F for midde +F for head at end of acceleration

Do you think that object forces aren't in balance on defined distance?And the distance isn't changed relative frameS? https://en.wikipedia.org/wiki/Reaction_%28physics%29 Force of length contraction is caused by reaction of forces connection to past distance which try to break off the object with force of acceleration.

Let's consider math of length contraction of ideal material. Forces of object at v are equal on contracted distance. Therefore acceleration causes forces of length contraction to mathematical middle of the object. For example masses of tail,middle and head are equal. Therefore: Force of head acceleration = F Force of length contraction for head at start of motion= -F Force of tail acceleration=F Force of length contraction of object for tail=F Therefore force of tail motion at start of motion=2F Force of head motion at start of motion=0

I am not against when religious people say that religion is useful , but only when they add that for backward people. Religious people should recognize that science is more important than their religion for humanity. Only then we can cooperate.

Inequality is danger for development of some people already now.

When culture creates rights inequality then our protection should destroy the culture.

Let's consider example when you try to accelerate head first. Head,middle and tail are connected by strong interaction. You,trying to accelerate head, increase distance between the head and the middle. Increase of gap increases strong interaction.Also acceleration increases speed and length contraction, which increase gap too. It creates more strong interaction even between the middle and the head.When the strong interaction force is bigger than acceleration force for the head then the strong interaction force accelerates the middle faster than the head acceleration. The tail accepts sufficient force for acceleration and reducing of distance to the head from bigger force of strong interaction.

I think necessary distance for forces balance is reducing therefore forces of counteraction have different shifts. Counteraction force of tail has blueshift, counteraction force of head has redshift to motion direction.

Even when they are accelerated at the same time then they are initially accelerated to different speeds. Physics should be idealized only by math.

.Agreed. If you have no such material then what proves that all parts of accelerated and contracted object are accelerated at the same time?

Really my math is considering acceleration and speed after one push. Thank you for idea about speed of force propagation. And so speed of force propagation is faster than c . And reducing object reduces speed of force propagation. Maybe therefore my math contradicts GR, but does it contradict QM ?

I confused some things. Speed of force propagation = r/t = r/[(gamma-1)r/(gamma*v)] = gamma*v/(gamma-1)

I didn't say that. Sorry. Seems I have made mistake about propagation at v, I will reconsider it. Do you think all railroad cars in train are simultaneously accelerated after a push?

They are not simultaneously accelerated because forces don't instantly transfer momentum especially when losing length of parts creates delay of subsequent collisions. Therefore speed of force propagation is v.
