Why does battery voltage drop when a load is supplied? I'm trying to think in terms of Ohm's law, and I can't figure it out.

James Webb achieves incredible focus

https://www.cbsnews.com/news/nasa-webb-space-telescope-near-perfect-focus/

After weeks of microscopic adjustments, NASA unveiled the first fully focused image from the James Webb Space Telescope Wednesday, a razor-sharp engineering photo of a nondescript star in a field of more distant galaxies that shows the observatory's optical system is working in near-flawless fashion.

The goal was to demonstrate Webb can now bring starlight to a near-perfect focus, proving the $10 billion telescope doesn't suffer from any subtle optical defects like the aberration that initially hobbled the Hubble Space Telescope. The galaxies in the image were a bonus, whetting astronomers' appetites for discoveries to come.

I'm self studying math and I'm going through How to Prove it by Velleman. Whenever I do the exercises I'll compare it to the solutions and if it's wrong what do I do? Should I comeback to the problem later after I've forgotten it and attempt it again? or do I write down the correct answer and just try to understand what's happened? or both?

The Continuum Hypothesis

No.14310583 ViewReplyOriginalReport
Z, Q, and R are uniquely different and measure different partitions of the number line. R measures complex numbers and is inherent in a measuring system of "disappearing" numbers where the boundaries between integer, rational number, and real number become extremely important. Discuss.
