Posted Apr20-13 at 09:51 AM by jambaugh

[DRAFT]
First step. Learn the requisite math. You cannot appeal to your intuition (yet) in understanding SR, it is counter intuitive if your intuition is based on everyday experience.

Intuition is a "quick-calc" tool of the mind which creates an answer based on experience. To apply your intuition to a new domain you must first experience that domain. There are two ways to experience SR. Spend hundreds of trillions of dollars developing new near the speed of...

Recall that moving electric charges (currents) induce magnetic fields. Put a (DC) current carrying wire next to a magnetic compass and you'll see the needle move.

Also changing magnetic fields induce voltages i.e. electric fields.

These two together are how a transformer works. The AC current in one coil causes a changing magnetic field which in turn causes an electric field (voltage) in the other coil which can then push a current. With different winding ratios...

Understanding the Twins "paradox"

Posted Jul6-09 at 03:34 PM by jambaugh

Here is a analogous phenomenon which helps see why there is no paradox in the "twins paradox".
