Do Cosmic Rays Spark Lightning? (h/t Stephen J)

Presumably, yes. I would think that the effect is not a big one, as ionisation of the air from
cosmic rays is not a big effect.

Is it the "cosmic" that is the problem for you, Ms. McMillan?

I’m beginning to understand that education needs to return wholly to Reading Writing and Arithmetic. Anything else should be discussed at a separate level because whats being taught is not fact, its just theories masquerading as facts.
I guess like our host I had believed that this was a well researched and well past intrigue fact, something no schoolboy/girl needed to enquire further about.

Yes. Next question?

Ha. Just try to buy a decent book on arithmetic. My favorite was one I used in the 5th form - a little explanation,
then hundreds of examples. I lost it, unfortunately. British schooling at its best.
When my wife complained that she was a little weak on arithmetic, I attempted to find a similar one.
The best I could find was one intended for British teachers of arithmetic - very good
but it was a little much for its purpose (for example, where students would be taught how to take
square roots manually, this book taught third roots. The intent was to keep the teachers ahead of
their pupils).

John I feel your pain,
Back in the mid-nieties feeling I needed to brush up on Trig (I’d forgotten everything I was taught and somehow I needed to get back up to speed for some azimuthal stuff for work) I did a similar search. I ended up doing an “Open University math course” that was suppose to be equivalent to the then “A” level. The syllabus promised that it would do Trig and Algebra.
One of the many things that woke me up to what was happening in the country of my birth. By the end of it I was shocked more than saddened, and needless to say I had not increased my knowledge nor aptitude for trig, but much better at using a "scientific" calculator.
Some one needs to start teaching stuff before the generation that can are no more and like the craftsmen trades before them they become lost to the world.

People who cannot solve a first order differential equation have no valid opinion about astro-physics, or any kind of physics at all.

I think I heard this 30 years ago,it explained the jagged yet linear path,pre ionized paths

I do tend to agree, but make that a second order differential equation, because that is what Newton's
second law yields. As in

d^2 x
----- + \omega^2 x = 0
dt^2

the undergraduate's friend. We pass too easily over the marvellous work done on celestial mechanics
between Newton and 1900, by which time the anomaly in the precession of Mercury's perihelion was
known to be real. It is a 10% effect, after all.

SA. Nat Geo. And so many more.
All pathetic PC shadows of what they once were.
