What is the newest installment of 'Random Thoughts' on Physics Forums?

[fresh_42]

Doesn't surprise me - you can't swing a cat round here without hitting an expert on something random like dealing with cat scratches to the head.

I recently said $p+V$ is affine for $p\neq 0$ and linear if $p=0$ for the sake of clarity to emphasize the difference. My greatest fear is, that someone starts a discussion on whether linear spaces are also affine spaces, just a special case. I don't really care and actually think so, too, but it would leave the OP completely confused.

Agreed, his views verge on the disgusting. Not a right- nor left- thing, just kind of disgusting.

I make everything right even when I make it wrong.

I will go along with that claim, you have an almost 3 likes per comment ratio whereas mine is approximately 1 like for every two comments

This means you are 6 times more something than I am

 

[StoneTemplePython]

That's the problem of trying a joke with the science crowd; they fact-check you when you try to use some license :) . I remember once I told the joke that the Vatican's logicians were working over time after the pope said: " I am sorry, I was wrong before -- I actually _am_ infallible" , and someone (seriously) gave me a pretty full argument for EDITwhy the Pope making a mistake did not contradict the doctrine of infallibility. Serenity Now!

Hihi. I have no clue as to why, but it gives me the impression that most of my likes appear to come from girls (mostly one though ). Looks like guys don't like me . Why you no like me boys, why? I should ask how to impress boys . What content would mostly impress boys.

In reality I must have a zero point something ratio, but because my posts are mostly on the lounge, my post count is stuck. Check @Greg Bernhardt number of likes. He's godlike . Most liked perhaps? Hmmmmmmm. Who's most liked I wonder. Must be Greg or a mentor.

That's pretty close to my mantra though Seinfeld is quiet on important things like the Internet and Ben Stiller, so I think Curb needs to be consulted as well.

With me its the musics tracks! I read mostly and only comment when I think I can add something

If the comment is not savaged then perhaps I have some understanding of that point or least have not posted something completely idiotic

I am still learning- I will check out Greg- just for interest.

When I post something idiotic:

 

[Psinter]

Me passenger. Vehicle moving at 65 mph in highway when suddenly another vehicle rear bumped us. Other car rolled and got vertically nailed onto the ground. Driver who bumped us was covered in blood and his passenger fled the scene with a broken ankle before the police arrived. Leaving the driver alone. No idea why she left, but I didn't care. Non of my business. Nothing happened to me .

The police officer cracked a joke and said: "You have an angel up your a**" To which I replied: "Yeah. He's telling me 'I'm tired of protecting you. I want a salary.'" And while we were cracking jokes the other guy was sitting there covered in blood and all confused. But an ambulance arrived quickly, so there's that.

I don't really know if I was lucky. I mean, could something bad have happened to me? I went to sleep thinking, but I'm not even worried. Just thoughts that float your mind.

I think I've accidentally killed a tree using a 3W led light :-(

Due to problems with delivery men not being able to find my house I erected a small sign illuminated by a 3w led wired to a light sensor so it only comes on at night. Six months later this nice 30 year old evergreen oak next to it has died. I noticed the light was illuminating the under side of the leaves at night but didn't realize it could kill the tree. Gutted.

 

[Tom.G]

Hmm... I wonder what the modus operandi of that is! Any plant biologists around?

Inadvertently, therefore Manslaughter.
But the tree would first have to be declared as a Person, as corporations are. Does that make a defunct corporation a victim of suicide?
Or one that was sued out of business a victim of Homicide?
Oh what a tangled web we weave...

Maybe I should just delete this post!

You don't understand how deeply some people feel the death of rocks and trees.

 

[Tom.G]

Unusual video. Of course we cannot know how others feel, we can however have empathy for them. I have felt sadness at the loss of a tree, often because of its connectedness to history - either personal or generally. For a rock - that would be a stretch, for me at least.

But at least on this site, most of us can discuss things and appreciate that others may have different views.

Be well, Evo.

I have felt sad at losing a plant. I love plants. Never lost a rock, maybe misplaced one.

 

[Tom.G]

Even just misplacing a shiny one that is worn on the finger could be, mmm... disconcerting.

I doubt your little light killed the tree.
Trees under street lights don't die. Those lights are probably brighter.
You have an N of 1.
Put your light on some other trees and report back.
Also, plant another tree to make Evo happy.

 

[fresh_42]

Trees under street lights don't die. Those lights are probably brighter.

My thought, too, but maybe the location matters. Street lights are mainly above plants or shielded by their caps towards the sky. So it could be, that the daily change of light direction for the leaves might have played a role.

Also, plant another tree to make Evo happy.

#MeToo.

 

[CWatters]

I suppose it could be a coincidence but adding the light was the only change I could see. Couldn't see any disease but I'm no expert.

Tree was planted by a now 90 year old resident of the village and is a relatively rare multi stem evergreen oak. A fabulous tree that we named our house after. Hope to replace it next season if I can find one.

 

[jim hardy]

Look around base. About this time of year rodents get after new bark. Voles eat a half inch strip all the way around right at ground level .
A few years ago after losing my third apple tree i thought it was a neighborhood hare. So we made him into a delightful stew.
Then my sister showed me what vole damage looks like.
Three years later when the voles got my fourth apple tree i gave up.

I did one of the most dangerous things in my life yesterday. No parachuting, jumping, climbing, etc. I went to this place to buy shirts, discounted at 5 for $10 ( and of good quality; the whole thing legit, of course). The dangerous part: I followed the salesman through several doors in order to get to the place where the shirts were. He could have easily just close one of those doors when I was far in , pull a gun/knife on me and I would have no way to get away from him. I could have made this post more dramatic by claiming to be posting from within the building, but I made it out. Not a smart decision on my part.

What the hell!? A tree falls over one should be glad that they were not under it - that is far as my emotion goes on that one.

As for rocks? Come on.

They have these flyers about lost dogs with pictures in them. Instead of just mentioning the type, color, weight of dogs. Can a human tell apart dogs by the difference in the dog's faces?

I have also noticed something similarly weird with people. In a crowded place, someone will shout : Lisa! And everyone will turn their heads, even many men. ?

You can use this phenomenon if you shout "Caution! Fresh paint!" instead, to make your way through a crowd, e.g. in stadiums.

For me, yes. However I also get a lot of clues by a dog's mannerisms.

I've beaten my head against a coding problem for several days and it finally submitted to my will.

I just remembered why I know so little about biology... It's gross, revolting. Why does it have to be so graphic? What's the big idea?

I feel I'm going to be sick. You don't want to see what I just saw. That's... I don't think I could ever get a degree on biology. Whatever you do, don't google frog dissection. Or dissection for all that matters. I'm... I'm just going to lay in the floor for a while. Don't mind me.

The grossness is something you can easily get used to.

Biology, itself, is the most intriguing of subject, very complex, yet still very approachable experimentally (including using a lot of physics).
Seeing anatomy is a, to me, is a expression of amazingness of biological phenomena (which extends from the atomic scale to the global scale) and the natural world in general.
It is also placed between physics and the less easily studied, but interesting, world of psychology.

I got over the grossness of it in grade school (biology class).
Now in my oldish age I do recoveries for an eyebank.
The actual recoveries are pretty fun for me (I am actually really good at dissecting things- got the Golden Scissors Award in neurophysiology class!).
The body exams for signs of disease can be kind of gross: blood, poop, puke, pee, feces), but since I have been doing this for more than a year and seen things like gunshot and car crash victims, do not much fazes me now.
I would suppose @berkeman has similar experiences.

I was lucky -- In my early emergency response training, "moulage" was used extensively. Moulage is makeup that looks like very realistic injuries. I don't want to gross out @Psinter so I won't go into a lot of detail about all of the different moulage variations that I've seen, but the big advantage of that kind of training is when you see it in a training situation you know it's fake (no matter how realistic it looks), which helps to keep it from seeming too gruesome in the training. And then when you see the same kinds of injuries in real life, you basically say to yourself, "I've seen that before", which keeps it from being a distraction or seeming gruesome. You just go straight to treating it without spending much time being distracted by the injury's appearance.

One of the most amazing pieces of moulage I've ever dealt with in training was at a mass casualty training event where a bomb had gone off in a crowd at a large political gathering on a high school football field. The shift I was on was in the middle of the night, and as my team and I worked our way through the field of victims (performing "triage", which is tagging the victims with their severity level so we can prioritize transport), I came upon a semi-conscious man with blast injuries, and no lower left leg. I thought to myself, "Boy that is amazing moulage! What did they do, bury his lower leg in the ground and make it up to look like it has been blown off?!" Turns out the actor/victim is a retired Army veteran who lost his lower leg in Afghanistan a few years ago, and he volunteers at these training events to act (very realistically!) like his leg was just blown off there in the scenario. Kudos to him, amazing realism!

Why does it have to be so graphic?

We have to thank the morbid curiosity of the guys who wanted to see how the human body was made and functioned.
The basis of medicine pathology anatomy physiology

Da Vinci is a good example, he supposedly did dissections to improve his art but I bet he was curious about what muscles tendons etc really were made up and worked.

His studio probably did not smell very nice given 16th C cleaning and sterilizing methods
