What Three Surprising Effects Follow Immedietly The Postulates of Special Relativity

I'm just wondering if anyone can help out here. I know the two postulates as set out by Einstein but just unsure of the 3 surprising effects.

I think its time dilation, lorrentz contraction and simultaneity failure but just not 100%

I guess that this is a question that has been posed by a lecturer, whose rather self-centred view is that the "three surprising effects" that will spring to everyone's mind are the same 3 in his/her mind.

Also what is intended by "immediate"?

I think your suggested 3 effects seem perfectly reasonable,
but as you say, we can't be 100% sure they are what the lecturer has in mind...

It would perhaps be interesting to see how many "immediate" effects others can come up with.

That looks like a text book problem in which the words "three surprising effects" and "immediately follow" were specifically used earlier in the chapter!

I ended up just discussing the 3 i mentioned above but yeh it was a very vague question he asked so hes getting my interpretation of it

Another is the unification of the electric and magnetic fields as well as the increase of inertia with speed.

The unification of the electric and magnetic fields was done by Maxwell and led to relativity.

My bad.

What I had in mind was that relativity showed that a pure E field in one frame is an electric and magnetic field in another frame. I.e.
https://en.wikipedia.org/wiki/Electromagnetism
In addition, relativity theory implies that in moving frames of reference a magnetic field transforms to a field with a nonzero electric component and conversely, a moving electric field transforms to a nonzero magnetic component, thus firmly showing that the phenomena are two sides of the same coin. Hence the term "electromagnetism".

Yes, different lecturers may offer different lists so what did the Man himself say?

Einstein lecture at the University of Potsdam 1929

As to the mechanical nature of the lorenzian ether, it may be said of it, in a somewhat playful spirit, that immobility is the only mechanical property of which it has not been deprived by H A Lorenz. It may be added that the whole change in conception of the ether which special theory brought about consisted in taking away from the ether its last remaining mechanical quality, namely, its immobility...........

.......Accoring to the general theory of relativity space is endowed with physical qualities; in this sense therefore, there exists an ether.
Classical (pre relativity) physics was founded on the idea of three basic dimensions, mass length and time (MLT)

Does the number three ring a bell, compared to the question?

These are all the qualities or properties that Einstein's relativity dramatically changed the world view of.

In different reference frames these properties will have different values and, according to einstinian relativity we cannot regard any of these values as the real one.
