Check auto parts stores, they should take it. However, they won’t take it if it’s contaminated with anything, like coolant. So instead I take it to my local dump, they have a place to dispose of oil and other fluids for free. Maybe that’s an option for you as well.
If you have the space, I would recommend learning how to change your oil yourself. It only takes some basic tools and can save you a lot of money in the long run.
My favorite myriapod is Arthropleura. Imagine a millipede the length of a car!
I wonder if you could make a decent model of plate tectonics with wax. Have a pan of wax heated from below, deep enough that the top is cool enough to be solid.
The best lesson I learned in chemistry class was to not put a wet beaker on a pre-heated hot plate
“Well, the good news is you get to have a disease named after you…”
There’s a program called Forscan you can get that allows you to tweak that kind of thing in Ford vehicles. I don’t know if other makes have equivalent software.

Is there a Redwall community? I’m tempted to make one but I have no idea how
Are you saying that if I picked up a copy of that differential equations book I might actually learn wtf is going on? Because I only passed that class with the help of wolfram alpha and never looked back
This one got me good because Saddam Hussein was the last thing I noticed
You’ve enlightened me. I love dragonflies too now.
Some kids at my high school tried that on their phones, but it never worked because all the other kids in the room would cuss them out for basically inflicting the entire room with mosquito-in-ear noises.
We put some raw chicken in a wasp trap once and my god, I’ve never seen so many wasps in one place. The thing was almost a quarter full by the end of the day.
If it’s an alpha or beta emitter, sure, you’re probably fine standing near it. But if you find yourself next to a chunk of a gamma emitter, you should probably run away very quickly
So there’s four types of radiation: alpha, beta, gamma, and neutron. When you’re talking about radioactive materials, it’s almost exclusively the first three. In addition to the inherent danger of the object itself, there’s also the danger of radioactive contamination: not making other things radioactive, but shedding bits of themselves as dust and then that dust getting on other things, or getting ingested/inhaled by humans.
Active fission reactions, like what goes on in the core of a nuclear reactor (or perhaps messing around with some plutonium and a screwdriver), produce neutron radiation. Neutrons can make other things radioactive, via a process called “neutron activation”, whereby the neutrons bind to the material and change some of the atoms into radioactive isotopes.
I hope that helps, and feel free to ask me anything else about radiation. I have some education about it thanks to my job, and I’m always happy to help other people understand it more as well.
More or less. The difference is that, if they really wanted to, they could very thoroughly clean the notebook and take most of the contamination off. I’m guessing they won’t because a) It’s a historical artifact and they don’t want to risk damaging it, b) the contamination is so low-level that it’s not dangerous as long as you don’t lick it or something, and/or c) there’s a bit of a shock factor in watching a scientist’s notebook make a Geiger counter freak out.
Well, childhood mystery solved. When I was younger, my family went to France to visit some relatives. One of the dishes we were served was a salad, and my mom told me it was called pee-the-bed salad. I was so confused and was terrified that I was going to wet my bed that night after eating it. I didn’t, but I had been wondering ever since then what it could have been and why it was called that.
