Handsome fella
With our warmer than normal december our suet feeders went "quiet" for awhile.
We then turned colder this week, and it seems like the words out that the buffet is open.
Still wondering what happened to that big glob of orange paint you had sitting out?
Kinda looks like he got into Trumps spray tan container
We had to give up the bird feeder.
It is impossible to keep the varmints away from it.
Squirrels, opossums, raccoons, skunks
I’m not even 100% convinced it should legal to feed wold animals.
Wild animals
Cayenne pepper.
When I taught at a previous college, I used to hang out with the ornithology prof. He told me it is believed that hot peppers evolved because (a) mammals hate capsaicin and (b) birds have almost no sense of taste. That plus bright colors means better seed distribution.
So I put that theory to work. A light coating of spray cooking oil and then toss in hot pepper until coated. First squirrel to take a bite jumped 20 feet and started wiping his face on the ground.
I was watching a video on youtube called:
A new way to visualize General Relativity
and I thought it was pretty good. I seemed to recall Kevin complaining about the usual trampoline visual that is used (found it 1/1/2017). So I figured I'd send him the link:

It shows how a stationary object starts accelerating. I thought it was pretty good.
Well, that is pretty darn interesting. Still a little taxing for this old brain, but fun to think about.
Yeah, that still doesn't work. He's using a grid to represent two different things -- spacetime curvature and geodesics through a curved spacetime. Those are very different things. So he has substituted one deception for a different, more abstract and harder to understand deception.
In a static field like the Earth's, the spacetime grid is static. It has to be. That's what static means.
It just isn't possible to represent 4 dimensional spacetime using 3 dimensional space. For one thing, the metric in spacetime (essentially, the Pythagorean theorem in spacetime) has a relative minus sign between the space and time parts. If you take the space intervals to all be positive, then the time interval is negative. But in a 3D spatial representation, all the intervals are positive so it isn't possible for one of them to stand in for time.
In fact, in a weak field like Earth's, almost all the curvature is in the time part. That's why Newtonian gravity works, because the time part is related to the potential energy.
Slicing is an ok idea, but what he is showing is a changing curvature sucking particles toward the Earth. That isn't true. The curvature doesn't change.
It's zero at night in Michigan, but the chickadees still show up in the morning at the feeder. Slightly ridiculous name, but those tough little things stick it out all winter long.
Nothing but cracked sunflower hearts for them. I got tired of shoveling that spilled grocery store crap from the ground under the feeder. Sometime I get a jay or a cardinal, or even a woodpecker.
this might be worth an extended debate among democrats. How do they convince themselves that people want this and that they will be rewarded for it?

“When the policy first passed in March, many experts hailed its potential to cut child poverty and hunger, and many Democrats hoped regular cash in families’ pockets would prove wildly popular.”
“That lukewarm reception has dismayed those across the political spectrum who advocate more generous aid to families.”
