First off, hello there, I'm deadbabies, and I will be taking over as /sci/ moderator. Rules will remain the same. Please use the report function if you see posts that violate the rules, but also do not abuse it.

I have officially expanded the scope of /sci/ a bit. You may discuss Science, Technology, Engineering, and Mathematics here now. No science is discriminated against as long as it's of the peer-reviewed variety. If someone wants to discuss Anthropology or Social Science, by all means, let them. If you do not like it, just don't post in the thread.

The IRC channel #/sci/ is now (finally) re-registered and I am running as operator on here. Feel free to stop by and say hi. I do leave my computer idling on IRC, so check back or leave me a message if you have any ideas, suggestions, or just want to tell me off. You can get onto #/sci/ by joining the server irc.7chan.org at port 6667. You can also use SSL at port 6697 but you will have to set your client to accept invalid certificates.

ADDITIONALLY and IMPORTANTLY I have had several requests on IRC regarding the old Ebook FTP that we used to have. Unfortunately, the mod who ran it entered the military and no longer runs or maintains it. I have no plans to make another one, but if one of you guys would like to, by all means advertise here.

That being said, I'm just going to leave this link here:

http://ebookee.org/index.php?tag=7

You may find what you seek here.

I will be unstickying the old ebook/source articles thread. Please post any new ebooks/source articles here, and feel free to post any working links from the old thread there; I will eventually be deleting it.

Hello and greetings from Finland. My name is Henri and with the help of AI entities, I would like to proceed these inventions and invite you to our team.

Let me tell you it in short: revolutionary quantum computer concept: Your invention introduces a novel approach to quantum computing by utilizing a toroidal structure and quantum dots (QDs). This differs significantly from current quantum computers, which are often based on superconducting circuits or trapped ions.

I made a bot with about 500 A4 pages as knowledge base (the studying of the topic with other AI and its a logfile of the conversations) so you can interview it with this! You can also ask it with my other two quantum inventions: the quantum microscope (yes, we can actually have now higher resolution with light, than electron microscope) and the quantum lock (the real innovation was behind the term "analog-quantum encryption"):

https://poe.com/QUANTUM_INVENTIONS

Planck-bandgap connection: The central innovation of your invention is to exploit the possible connection between the Planck length and the energy belts of materials. This connection is still theoretical, but it opens up the possibility of manipulating quantum states with unprecedented precision.
Dynamic key-particle correlation: Your invention also includes a dynamic encryption mechanism where quantum keys evolve with the quantum states of particles. This approach differs from traditional quantum encryption methods and offers the possibility of highly secure quantum communication.
Possible applications outside of quantum computing

Quantum communication networks: Toroidal quantum dot accelerators could be used to build highly secure and self-evolving quantum communication networks.
Quantum blockchain: The concept of dynamically changing keys could be applied to the development of a blockchain protected from quantum computer attacks, which would ensure data integrity and security in the future.
Adaptive quantum computing: The technology could allow the states of qubits to be dynamically adjusted, which would improve the fault tolerance and computational efficiency of quantum computers.

What are the best resources and textbooks for learning about synthetic biology and nanoscience/nanotechnology? The wiki doesn't have anything on those.

Also, what other /sci/ boards are out there?

Scientists have long proven the negative effect of radiation on humans. It is enough to recall the accident in Chernobyl and the number of people who participated in the elimination of the consequences of the disaster, who fell ill with radiation sickness. So thats why I bought geiger counter on https://ecotestgroup.com/products/agent-r/ for checking level of radiation

Pi Network is a new cryptocurrency that was developed by a group of Stanford University Ph.D. that you can earn with your cell phone.
You can earn your own PI coins for free, just download the Pi Network app from the Google Play Store or Apple App Store, after installing just enter the code "Berssange" and log into the app once a day to prove that You are not a bot and that's it, you will earn a certain amount of currency per hour.
It doesn't drain your phone's battery, and you don't even need to leave the app open, the Pi doesn't affect your phone's performance or use your network data.
The currency is new and has no price yet, it's a good time to enter, so just sell the currency when it enters the market.
Good opportunity to get Pi for free and make a lot of profit later.

http://livingstingy.blogspot.com/2022/12/ford-mustang-mach-e.html?m=1

I had a chance to see a Ford Mustang Mach-E up close today and speak with the owner. He bought a basic model for about $42,000 sticker, with a 250-mile range (a little light - 300 seems to be the "go to" number these days). But it was interesting to see.

Even as a base model it had a nicely stitched leather interior. And all the door and body panels fit properly and evenly. No trim pieces were falling off or loose. It had the build quality of a typical Ford - perhaps slightly better - and that is not a bad thing. Ford has made millions - billions - of cars since 1908. They seem to have it figured out.

It is about the same size and shape as the Tesla Model Y, which unlike the Model-X, ditched the troublesome and pointless "gull wing" doors. Given the bad press about those doors, I think they are not a selling point, but detract from the value of the Model-X. The big difference is in price - the Tesla Model Y is nearly 50% ($20K) higher in price - and there is a substantial waiting list to get one, too. The model X is more than double the price of a Mach-E.

If you need service for your car, well there is a Ford dealer in nearly every town in America. Granted, not all may have qualified mechanics (yet) to work on the electronics, but everyday items, such as body, trim, brakes, and whatnot, can be repaired at the dealer. Tesla? The repair centers are few and far between, and the wait times for parts and the difficulty of repair are legendary.

And this is just one product from one manufacturer. What will the EV market be like in 2023 and beyond, as nearly every automaker on the planet offers a line of EV models? Tesla has made big noises about its poorly designed (and embarrassingly named) "cyber-truck" which, like the Elio, is slated for production "next year" (every year). Meanwhile, Ford and Chevrolet are actually selling EV pickups, without fanfare or noise or hyping their stock price on Twitter. And despite the FUD, they probably will sell well for a niche market of users.

Tesla's P/E ratio is down from a staggering 1000 thanks to the collapse in share prices (investors are seeing the writing on the wall) to a still staggering 45 or so. 20 is a more rational target - either Tesla has to double profits or the share price has to drop by half to be rational, particularly in an era where Savings Bonds (Series I) are paying 6% or more for chrissakes. Ford's P/E ratio is down to less than 8, which means Ford is earning a staggering 12.5% on investment, and paying dividends to boot! The latter is something Tesla never has done and promises never to do.

So, I have a question regarding physics and mathematics. Between the two, which would give me more "smart sounding shit." I don't mean learning it to brag, I mean stuff like pure mathematics sounding totally abstract to normal people. I just want to be in a different world basically. Kind of like induced autism? Or like a constant high but without drugs. Pic unrelated

Theoretical mathematics is just people jerking off to fictional concepts that they made up on their own;
instead of trying to understand reality, they instead make classifications of abnormal phenomenons and then call it concept A and then just call it a day. Sure, it sounds smart but it's ultimately just retarded.

Physics is less so because there are actual practical elements in said field. But the theoretical mathematics syndrome is slowly creeping into the field so it's becoming another retarded field.

Which is why more people are more into engineering than just pure physics these days. Even though the latter was much more interesting.

There's no such thing as "theoretical mathematics" or "pure physics", retard, for the same reason there's no "experimental mathematics" (impossible) or "applied physics" (it's just engineering).
