Does wave-particle duality rely on accepting the Copenhagen interpretation?

If you're a scientist that subscribes to the many worlds theorem, does that mean you do not accept wave particle duality?

Power generation. What determines the voltage and current specifications of a generator?

Posted: 08 May 2019 03:12 PM PDT

I have some electrical/electronic training and understand the basics concepts of torque relating to current and frequency of AC relating to rotation speed. What I'm asking is, if I go to a engineer and say I need a generator that outputs x volts at y RPM and provides Z current, what characteristics are they gonna utilize to create this? Coil length, magnetic field strength, # of coils etc?

How is a continent defined?

What were some unique traits and criterias considered while grouping landmass together for one identity?

Pardon me if it's not defined using scientific logic but just by some random humane idea.

What is a phantom power supply that can have a CC or a CV?

Posted: 08 May 2019 06:37 PM PDT

We are developing an electrical test for motors. Without going into details for that one colleague suggested to buy phantom power supply which can have a constant current or a constant voltage. But this is not logical to me. How does this device work? Does it change its resistance (U = IR) to keep one parametar constant but not the other or no?

Are any galaxies actually colliding?

Posted: 08 May 2019 01:30 PM PDT

I've heard of galaxies interacting but are any actually colliding? I've heard they are so vast that galaxies interacting doesn't really fit our idea of actually colliding (i.e matter hitting matter).

Why are immunotherapies(CAR-T, Antibodies) less effective against solid tumors?

Posted: 08 May 2019 04:56 PM PDT

Adoptive cell therapy/CAR-T is new and exciting but for now is only approved for blood cancers. Is this technique a dead end or can it be modified for solid tumors?
