you know how we can put those electrodes in the heads of animals ?
we put one in the head of a rat once and they made it move with a joystick

do you think the government would weaponize i mean we could do tigers?
if we wire them right we could keep them moving through death

in theory you could do it to humans it'd be almost like zombies

Maybe if you start by putting toilet cleaner in your toilet, shampoo or showergel may also work because most peoples have terrible hygiene so they live in a house with poop or diahorra in the walls of their house.

Step 1. Clean your toilet with lavender based cleaning product.
Step 2. Flying bugs and other insects are attracted to lavender.
Step 3. The insects eat the shit and die.
Step 4. If the insects are dead than they will not poop on your property so cleanliness is improved for a decent amount of time.

im currently studying comp engineering/ comp sci, and am doin fairly well, but i feel like 95% of my program is more focused on comp sci and coding and we are never really learning about actually engineering.
what i'm wondering is, what other fields of science (or any other subject) do you guys think are important for someone in my field to have a decent understanding of? also, what are good resources to check out for staying up to date with whatever you recommend / good starting points? any subcirclejerks, news sources, podcasts, anything that's a good resource for learning i'm most interested in graphics programming as well as anything audio related, sound manipulation, etc. but really any recommendations are appreciated
thanks in advance!

I want to finally prove Creationists wrong. I'm tired of everyone being able to say "EvOlUtIoN iS jUsT a ThEoRy!!!". I want to finally prove them wrong.

So my idea is we find the last homo species that wouldn't be considered human but has the greatest amount of high quality genetic material available then we clone it. We create ten zygotes that go into 10 women. At very least when we find, assuming it reaches the form of a fetus, when it begins to become unhealthy which I'm sure will happen we abort it and then we dissect the fetus and find abnormalities that differ from human fetuses at the same time. I don't think we are going to be able to get a full baby but I think it would be interesting assuming conservatives don't get their panties in a bunch.

Could we do it? What is the closest relative we could clone without breaking human cloning laws? If we can't do it now, what would it take to be able to do this scientifically speaking?

Considering the mountain of existing scientific evidence and the enormous number of creationists that still exists, I doubt anyone could achieve this. Creationism is faith based, they're playing by a different set of rules. Hell, there are people who believe the earth is flat. There will always be fringe beliefs and dubious, ideologically-motivated science, we can only hope that there will be less in the future.

Sup /chem/,

I'm taking general physics 2 this semester and I have the same professor I had for physics 1. Now it's just algebra-based, and I've been through calculus, so I was able to breeze through Newtonian mechanics and all that. However this semester is about electromagnetism, circuits, and optics. All topics I have zero exposure to. Now the professor is new to teaching at the college level, his experience is teaching middle-schoolers. He is very (obliviously) condescending and talks to his class of adults like they are 12. He constantly makes sexist or racist jokes (but on the fence enough to not get in trouble) and is always ranting about his personal life or past experiences. When he finally does an actual problem on the board he always struggles with basic spelling and arithmetic, and often fundamentally misunderstands the physics concept he is trying to teach. Several times last semester I had to quietly approach him after class and explain how everything he lectured that day was flawed and the next lecture he would try to fix his fuckup but he ended up just giving everyone lots of freebies on the exams.

My concern is that in this new semester of material I will not get a good exposure or foundation in these topics and might be lost in future courses. Especially electricity and circuits, I really want to learn more about that. I am worried he will teach me some fundamental concepts backward or something. Other than pre-reading the text before class what would you guys recommend to get through this course when the professor is a complete idiot and in my opinion not qualified?

I watched a pic related video on youtube (https://m.youtube.com/watch?v=WAI7Lu4UFi4&t=1s) where a guy called Backyard Scientist who lives in Floriduh mounts a crazy huge laser to the top of his truck. He says his laser isn't as powerful as the one that Styropyro (another youtuber) made, but it's good enough for me!

The rub is that I don't know a hell of a lot about electronics, or lasers, but I can follow a set of plans just fine, and it doesn't take me long to figure things out. I know it would be more educational if I started at the bottom in both of the relevant subjects, but I'm impatient so no. What I would like to find is a set of plans, and possibly a tutorial for how to read those plans if they're over my head, for a giant laser that I can build in my garage. Just the essentials (laser, driver, power source) is more than enough to give me all I need for success.

You might ask why I want this kind of thing. I want it because it's dangerous and cool and no law currently prohibits it. Because inside every man is a little boy who still gets a kick out of playing with matches and that little boy is selling all his baseball cards to buy a huge laser.

I have two designs in mind. First is the "bazooka" style. One large beam (4 inches?) directed with X/Y servos. This design allows for focusing of the beam to achieve maximum beam intensity on a target regardless of range (to a limit). Second is a split beam with several (10?) "emitter" mirrors each with X/Y servos that are all synchronized. This design allows me to spread the beam out over several feet to achieve a wide area of effect.

Mad Science Forever!

Well then I'd better not use it in a war.

As it turns out, a pulse laser tattoo removal device (available on ebay for under $600) would probably work as well, if not better. 1000w output with 2 kilojoules over about 6 nanoseconds. Only, it doesn't make that beautiful massive continuous beam that I find so alluring. But for sheer destructive power it's hard to beat

Also, afterthought, I realized that those holiday laser displays with the spinning diffractor lenses would work for spreading the beam out, but a large diameter beam would be too much for an off the shelf lens and the pulse laser would probably just blast a divvit in the lens surface. I'll have to do some more research.

Look up the landsat program. That's a good place to start. I can't find the really useful website that lets you search the data easily. But here's an example of what kind of data it has: https://earthnow.usgs.gov/observer/

If you really get into it, you can actually get a Software Defined Radio for like $50 and download the data directly from the satellite. You can see some circlejerk nerds doing that here: https://www.circlejerk.com/r/amateursatellites/

Phenethylamines are generally more stimulating. After all, amphetamine is only a methyl group away from phenethylamine. That's the only major difference IMO.

Every compound is a bit different but tryptamines and phenethylamines are both primarily 5HT2a agonists and not wildly different.

I think this is right. Both classes of psychs primarily act as partial 5ht agonists. But psychedelic phenethylamines sometimes also have similar effects to the stimulant phenethylamines. MDMA is the classic examples of this.

>Global warming hews to the most pessimistic projections, rising by 5-6C during this century and a further 3-6C in the next century. This additionally assumes that geoengineering efforts are unsuccessful. In this scenario, the Arctic melts, the Greenland and Antarctic ice shelves start collapsing, the Amazon burns down and turns to desert, and the great methane reserves stored in the Siberian permafrost and Arctic clathrates go kaboom, further accelerating global warming. The shocks in this worst case scenario will probably result in a global unraveling, technological regress, and population decline or collapse to perhaps one billion. But the chances of this are really marginal, probably less than 1%.

only a full ecological collapse could wipe out humans. Global warming could well lead to a dip in our numbers and lead to a global dark age. Keep in mind that a lot of areas will actually be improved for human habitation (polar regions for instance), As it stands pre-industrial peoples have succesfully colonised every continent except for Antarctica, so the chance some pockets would survive is pretty high.

As for how to save local biospheres from collapse and to build more resiliency into our societies: regenerative agriculture

I enjoyed UC Irvine's chemistry courses, but I was there while they were begin filmed. I'd imagine all of the schools you listed would be great and I doubt you'll find anyone who's taken basic Ochem from multiple schools anyways.

Ochem was my favorite subject in school and I really hope that you learn more about it. The things I learned in those classes really do inform me about everyday reality in a way that really deepens my daily experience.

As much as I recommend learning chemistry, it's important to note that the challenges of recreational drug synthesis are not chemical challenges. Most syntheses are pretty straightforward. The hardest things to do are obtaining precursors and avoiding the law. There are clandestine labs out there though, which means buying drugs will usually be cheaper than making them.
