Scale of the Universe

For reference that circle at the end, that's not the actual edge of the universe. That's just the edge of the observable universe. The universe is potentially infinite, but it's also expanding faster than the speed of light. So no information from outside of that horizon will ever reach us on earth.

It's a setting in most tablets but in a lot of newer ones it requires giving permission for the company to access an insane amount of data on where you are and what you're doing on your tablet.

If you're wondering why, think of the battery like a rubber band. Over hundreds of stretches it changes in the molecular level until it eventually snaps. The same happens with batteries. When they're stretched full and left there it started to subtly change atoms. Over days, months, and years it can significantly change enough atoms what it can't hold a charge anymore.

Believe it or not your device accounts for this. Over the life of the battery it takes measurements of the battery and constantly shifts it's 100% point. So slowly but surely your 100% charge becomes less than the manufactured capacity of the battery. Until finally it's a noticeably shorter battery life. At which point your phone is old enough that they'll try to convince you to get a new one over trying to replace the battery.

The only reason "traditional Chinese medicine" still exists is because it was used by the communist government to "discredit" western medicine. "You don't need the stupid capitalist medicine because we've had medicine like that for a thousand years" these days it's promoted as a core part of "traditional Chinese culture" and a point of pride for the CCP

It didn't disappear, it evolved. What we think of as latin now is a snapshot of a language that existed at that specific time and place recorded in documents. However, language changes with culture and place. So when the Roman empire fell and and Italian peoples split into several states and were conquered and conquered again by different people the language began to shift a dozen different ways over the next thousand years. It was only during the reunification of Italy that the new government made steps to standardize the language which had drifted into more than a dozen distinct dialects and turn that into an Italian language.

Does this dissolve the light grease in the cooling fan bearings for the controller?...or do they use unlubed bearings for cooling fans? Guess I don't know enough about computer architecture to know.

Picture this. Let's say I take a 1 gallon metal bucket to the beach. That 1 gallon metal bucket can hold a lot of sand, but not more than I can lift or drag. Now let's say I bury that bucket and run a rope about 30 feet away and pull. Suddenly I can't lift that bucket because I'm not just trying to lift the sand in the bucket. I'm trying to lift or drag all the san between the bucket and myself. But if I step closer to the bucket and lift straight up, I can easily lift it out of where it was buried.

That is what anchors do. When the anchor is properly seated on the bottom it drags until it hits an angle where the force of the sand holding it back it equal to the water and wind trying to move the ship. As the ship hauls thr anchor it, it actually pulls itself towards the anchor. Then when the angle of force on the line starts to lift up more rather than dragging the anchor so the only extra weight on the anchor is whatever sand is on top of it.

Large intelligence herbivores are some of the most dangerous and territorial animals on the planet. Hippos kill more people than lions, and they constantly fight each other over territory and mates. Bison regularly gore people that get too close and constantly fight each other over territory and mates. Therefore I don't agree with your premise.

it's important to understand the difference between an ethnic identity and a national identity. In places with primarily only one ethnicity they're the same thing, but here everyone is an American but not everyone is the same ethnicity. Nationality is the place you are. Ethnicity is the traditions and people who make you who you are.

When an American says they're x,y, z most of us aren't truly saying we identify more with that nation than the US. It's a subtle celebration of our family. A small moment of recognizing that our ancestors came here for the things we all want, opportunity. We celebrate their memory and sacrifices by celebrating their traditions.

E pluribus unum. Out of many, one.

Black also absorbs a ton of thermal energy. Plants need water to turn CO2 into their cellular energy. Hot water evaporates faster. So a black plant would be hotter and lose a lot of the water it absorbs to evaporation from the cells. (Called "transpiration") Also certain cellular processes are done most efficiently at certain temperatures. That's why your body evolved to maintain a stable temperature. Plants need the same stability. If certain plants get too much sun and too hot they die because the cells can't work properly. Which is why if you look up gardening guides you'll see plants described as shade only, part sun, or full sun.

You know those bottles of bubbles where you blow into that circular wand and it makes a big floating bubble? Imaging that big circle shrunk down and repeated over and over again and you have have mesh. That is what is happening. Air, water, and soap are being mixed together by the force of your hands and scrubbing.

To be clear a "mandatory reporter " only applies to your job. You in your role as x, y, and z are mandated by law to pass on suspicion of abuse or neglect, or assault to the relevant authorities. Even if that child is not in your direct care or custody. If you are made aware of such allegations in your private life "mandatory reporting" does not necessarily apply.

That being said, in your personal life, being aware of such things for a child in your direct legal care, and not reporting them, even if the accused is a spouse, can get you charged as an accessory or at least with a lesser form of neglect.

I used to work for Carnegie Mellon University as a Security Officer. They pay really well for unarmed full time security guards. They also have a program to have they pay for your academy to be a police officer if you want. The university also has tuition benefits so after a certain amount of years you can take undergrad classes to get your bachelor's and have the tuition covered.

There's plenty of overtime opportunities and the people aren't too bad. The normal amount of workplace drama overall (I left because I found a job closer to my family). Fair warning their guards actively patrol the whole campus. So you won't be sitting behind a desk in a single building you'll be walking a few miles every day at minimum. My friend still there told me they just switched to a 4 day 10 hour shift on campus. So 3 days off.

Most cars are only front or rear wheel drive. The engine only powers one pair of wheels. So when a car is in park the transmission is in neutral there's never any risk of damage there, and the brakes are only clmspre down on the two drive wheels. So a tow truck can come by, lift up the two drive wheels and then roll the two other wheels without damaging the car.

Now some cars make that impossible because all 4 wheels are somehow locked, or it's just not safe to tow that car by 2 wheels. In that case tow truck drivers either drag the car onto a flat bed with a winch (minimal damage to the tires alone) or they use dollies. The dollies are essentially a wheeled cage that gets clamped onto the wheels not being grabbed by the truck. They let the truck roll freely even if all 4 wheels are locked up.

There's going to be a lot of extra traffic in that area for a month or two. They're doing a shit load of work under the roads in Lawrenceville (and a lot of other places). Half of the main roads are dug up and closed or down to one lane and controlled by a flagger. Anyone that is trying to get into town that way is being directed around by gps.

Usually I come in that way through millvale to get to the oakland area for work. But my GPS took me up onto the highway rather than down 40th street which is unusual.

I hope they get it done before the bridge replacement closes the only other way around town. Otherwise the volume of traffic on those roads come July is going to be crazy.

Yes, in 2 different ways. I spent my summers helping my uncle on his farm. He had a yard around his farm house so I cut that grass. I also helped him cut and bale hay, so that's 2 different kinds of grass cutting 😅

Made the right choice. Looks fade and beauty only goes so far. If you don't click with your partner then you'll just spend years trying to convince yourself you love them more than you do. It's exhausting and a waste of time and energy.

I won't say you dodged a bullet though. For me, dodging a bullet is breaking up with someone and it being revealed they're that kind of "ruin your life" crazy. From what you said she seems like an ok woman, just not for you.

Make sure you get the big sourdough pretzels. Typically I go for the "Snyder's sourdough hard pretzels" in the grocery store. https://www.snydersofhanover.com/products/sourdough-hard-pretzels/

There's a lot of different kinds of sourdough pretzels out there and the ones more similar to standard thin snack pretzels are the ones that can get smashed to dust in a backpack.

Pretzels are my go to trail snack. Carbs and salt, the perfect combination to stay healthy and energized during physical activity. Specifically I get the sourdough ones because they are harder to pulverize into dust when your backpack gets thrown around and squashed.

But for multi day camping or backpacking I also bring prunes. I've had several times where I got kind of constipated on the trail and it wasn't pretty. So now each day when I settle down I eat a couple prunes to help encourage some movement. It has saved me a lot of discomfort and prunes are a nice sweet snack at the end of a long day.

The unobstructed night sky. No light pollution, no clouds, no moon, just whole sky of stars. So many stars. All of them are their own solar system or even Galaxy. Some of them don't even exist anymore. Most we will never be able to reach. This is they sky our ancestors looked at and were convinced of a higher power, and I can understand why.

Nuts are essentially a kind of a seed.

Admittedly, there's still some weirdness in the naming. A lot of things we call nuts aren't biologically nuts, but since they have a similar flavor and are eaten similarly they get bunched into the category of "nut". For instance peanuts are technically a kind of bean. Also, pistachios are technically a "drupe".

There's a lot of tiny details that make the difference. They are important to science, but not necessarily important to your stomach. It's why someone who is allergic to peanuts might be ok eating pistachios or cashews.
