A total eclipse of the US

[redpoint5]

I'll start this thread to talk about the eclipse.

A few days ago I realized I had to be in Medford for work Friday (a few hours from now). It's a 5hr drive under normal conditions, but not wanting to risk the agony of traffic, I booked a flight. How horrible am I for hoping that Saturday morning i-5 traffic is a nightmare to justify my decision to fly?

Anyhow, I'll be heading to my parent's farm in Salem on Sunday for a pre-eclipse party, camping out, and then photographing the thing Monday morning. I wish I had one of those 360 degree cameras to capture the event. Even better, a drone.

Hey Freebeard- you watching from home, or are you traveling somewhere?

What does everyone else have planned?

It's something like 72% of a total eclipse where I am. I will be attempting to photograph the eclipse through a #10 welding shade. Seems to work fine for normal sun photos.

My parents moved a little north of Idaho Falls, ID last year, so they're almost right in the middle of the totality. My wife and I will be heading up Saturday night or Sunday morning, whichever looks better for traffic.

I don't like giving out clues to my person or whereabouts on Internet, but what the hey — this is a twice in a lifetime opportunity.

My son shall bring his Parrot drone, and my niece is having a crew down from Potland that will bring their electric guitars. My brother that lives [literally] in the Sea of Cortez will be there. The two of us saw the last one at the Stonehenge replica at Maryhill, WA.

How many bricks would it take to make your own Stonehenge replica?

I keep wondering the cheapest way to make a long pinhole camera. If I tacked together four 2x4s that are twelve feet long, how large would the image be if it is actually from a pinhole?

It's easier if you start with car bodies:

If I knew the right terminology I would have my answer already.

Paraphrasing the Charlie Rose quote: "Knowing where to look is 95-percent of getting the right answer."

Much of the reason I mentioned it was hoping someone would have the information or at least the right keywords.

So you're saying you didn't click the helpful link? Something against DuckDuckGo?

Old Tele man — Have a gander at Goethe's Color Theory

Goethe's book provides a catalogue of how colour is perceived in a wide variety of circumstances, and considers Isaac Newton's observations to be special cases. Unlike Newton, Goethe's concern was not so much with the analytic treatment of colour, as with the qualities of how phenomena are perceived. Philosophers have come to understand the distinction between the optical spectrum, as observed by Newton, and the phenomenon of human colour perception as presented by Goethe—a subject analyzed at length by Wittgenstein in his comments on Goethe's theory in Remarks on Colour.
