The basics and some applications of special relativity: Relativistic nobel prizes, the concept of relativity, E-equals-m-c-squared, time dilation and the (in)famous twins.
This page contains an overview of those of our Spotlights on Relativity dealing with the foundations and applications of the special theory of relativity. In the category Basics, there is a text dealing with the meaning of “relativity”; under the heading Time, you will find texts dealing with simultaneity, time dilation and the famous travelling twins, while under Energy and mass, there is some information about Einstein’s best-known formula. Under Miscellaneous, you will find a text describing all relativity-related Nobel prizes.
A brief overview of special relativity can be found in our introduction Elementary Einstein, in particular in the chapter Special relativity.
How motion influences waves, or other kinds of ever-repeating signals, in classical physics and in special relativity.
How relativity can reconcile statements that, at first glance, appear to be contradictory
Special relativity and time
More about simultaneity, time dilation and the famous case of the travelling twin
A simple thought experiment with light clocks – clocks in which light keeps stroke – allows the derivation of time dilation.
Why it is necessary to define simultaneity, and how best to go about defining it.
How you can picture the relativity of simultaneity and time dilation, using a simple geometric analogy
Why the so-called “twin paradox” isn’t really a paradox
How one can picture the situation of the travelling twin, using a simple geometric analogy
Energy and mass
Some background information about the most famous formula in all of physics
Why Einstein’s famous formula tells us that the whole, as far as mass is concerned, is often less than the sum of its parts
The subtle connections between Einstein’s formula, nuclear fission and nuclear fusion

"Kutokana na nadharia ya ""relativistic,"" ambayo ni nadharia ya nadharia ya ubinadamu, nadharia ya ""relativistic,"" ambayo ni nadharia ya nadharia ya ubinadamu, nadharia ya ""relativistic,"" nadharia ya ""relativistic,"" nadharia ya ""relativistic,"" nadharia ya ""relativistic,"" nadharia ya ""mc-squared,"" nadharia ya ""time dilation"" na ""twins.""" "Hii ni sehemu ya ""Spotlights on Relativity"" ambayo inazungumzia msingi na matumizi ya nadharia maalum ya upendeleo." Katika jamii ya misingi, kuna maandishi yanayohusu maana ya 'uhusiano'; chini ya kichwa cha wakati, utapata maandishi yanayohusu wakati huo huo, muda wa muda na mapacha maarufu wanaosafiri, wakati chini ya nishati na wingi, kuna habari kuhusu formula ya Einstein inayojulikana zaidi. Chini ya Miscellaneous, utapata maandishi yanayoelezea tuzo zote za Nobel zinazohusiana na nadharia ya upendeleo. Maelezo mafupi ya nadharia ya upendeleo maalum yanaweza kupatikana katika utangulizi wetu Elementary Einstein, haswa katika sura ya Upendeleo maalum. Jinsi mwendo unavyoathiri mawimbi, au aina nyingine za ishara zinazorudiwa-rudiwa, katika fizikia ya kawaida na katika nadharia maalum ya upendeleo. Jinsi Relativity inaweza kuunganisha taarifa kwamba, kwa mtazamo wa kwanza, kuonekana kuwa kinyume Relativity maalum na wakati Zaidi kuhusu simultaneity, muda dilation na kesi maarufu ya kusafiri pacha majaribio ya mawazo rahisi na saa mwanga - saa ambayo mwanga anaendelea stroke - inaruhusu derivation ya muda dilation. Kwa nini ni muhimu kufafanua wakati huo huo, na jinsi bora ya kwenda kuhusu kufafanua yake. "Kwa nini ""paradox ya mapacha"" sio kweli ni paradoksi? jinsi mtu anaweza kuelezea hali ya mapacha wanaosafiri kwa kutumia mfano rahisi wa jiometri? nishati na wingi: ""Kwa nini formula maarufu ya Einstein inatuambia kwamba jumla, kwa kiasi cha wingi, mara nyingi ni ndogo kuliko jumla ya sehemu zake?"" uhusiano wa nadhifu kati ya formula ya Einstein, fission ya nyuklia na fusion: ""Mtazamo wa jumla wa tuzo za Nobel zinazohusiana na fizikia ya relativistic: Jinsi ya kuamua nafasi yako kwa kutumia ishara za redio na satelaiti na nini nadharia ya upendeleo inafanya na jinsi ya kuamua wakati wakati wowote na mahali popote kwa msaada wa kipazaji cha redio."""
