EPR may refer to:
Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a technique for studying materials with unpaired electrons. The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but it is electron spins that are excited instead of the spins of atomic nuclei. EPR spectroscopy is particularly useful for studying metal complexes or organic radicals. EPR was first observed in Kazan State University by Soviet physicist Yevgeny Zavoisky in 1944, and was developed independently at the same time by Brebis Bleaney at the University of Oxford.
Every electron has a magnetic moment and spin quantum number , with magnetic components and . In the presence of an external magnetic field with strength , the electron's magnetic moment aligns itself either parallel () or antiparallel () to the field, each alignment having a specific energy due to the Zeeman effect:

The EPR paradox tries to prove that quantum mechanics is wrong.

This video responds to a question about the EPR Paradox. It is explained in simple terms (no maths) but requires knowledge of some of the basics of Quantum Mechanics in my other videos. Too simple for experts!
D'un niveau de sûreté accru, le réacteur EPR™ affiche des innovations majeures, notamment pour la prévention d'une fusion du cœur du réacteur et de ses conséquences potentielle. Il présente aussi une extrême robustesse contre les agressions externes: fort séisme, chute d'un avion militaire ou commercial. Face à toute situation anormale, les systèmes d'exploitation et de sûreté du réacteur EPR™ apportent des réponses adaptées.(Copyright Image & Process)

You run for cover
Stick your head in the sand
You deny you're wrong
Say you don't understand
The ways and means
Don't mean a thing with no green
And your, body of work
Ain't nobody to be seen
The only choice to make is
Paper or plastic
So ya, do something drastic
And ya make it fantastic
You keep on fishin' for
A way to succeed
It's the, only way
For the big dogs to eat
Just ride the wave
Everybody rave
Don't be a slave
To the things you crave
Temptation make you
Want the things you don't need
Buy them, boogie shoes
And spend to
Feed the greed
You spin the wheel
And play the numbers you feel
Bet them double zeroes
And you'll, be a hero
Just ride the wave
Everybody rave
Don't be a slave
To the things that you crave
Feeble
Evil
Boring
People
Sneaky
Freaky
Lonely
Schemers
Fowling
Scowling
Bottom
Feeders
Musing
Amusing
In
Betweeners
Just ride the wave
Everybody rave
Don't be a slave
To the things you crave
