Spörer's law refers to a phenomenon observed in solar physics related to solar activity and sunspot cycles. Specifically, it describes the relationship between the latitude of sunspots and their appearance over the solar cycle. According to Spörer's law, sunspots tend to form at higher latitudes during the early phases of a solar cycle and progressively appear closer to the solar equator as the cycle progresses toward its maximum phase.
The weather in 2009 varied greatly around the world, with significant climate events influencing various regions. Here are some notable weather-related events and trends from that year: 1. **Global Temperature**: 2009 was one of the cooler years of the decade, with global average temperatures slightly below the long-term trend. 2. **El Niño**: Early in the year, the tail end of the El Niño phenomenon influenced weather patterns, leading to unusual conditions in several regions.

Lists of extreme temperatures refer to records of the highest and lowest temperatures ever recorded in various locations around the world. These lists can be categorized by different criteria, such as: 1. **Highest Recorded Temperatures**: - This includes the highest air temperature recorded on Earth. The highest officially recorded temperature is 56.7°C (134°F) in Furnace Creek Ranch, Death Valley, California, USA, on July 10, 1913.
Berkelium is a synthetic, radioactive element with the symbol Bk and atomic number 97. It was first identified in 1949 by a team of researchers at the University of California, Berkeley, hence its name. Berkelium is classified as an actinide and is part of the f-block of the periodic table. Berkelium is produced in minute amounts through the bombardment of curium with alpha particles or by neutron capture in a nuclear reactor.
SplitFire spark plugs are a type of aftermarket spark plug designed to improve engine performance, fuel efficiency, and reduce emissions compared to standard spark plugs. The distinguishing feature of SplitFire spark plugs is their unique design, which includes dual ground electrodes. This configuration allows for multiple spark discharge points, which can enhance ignition efficiency and combustion. The design aims to create a better flame kernel, leading to more complete combustion of the air-fuel mixture in the engine's combustion chamber.
Ignitron is a type of semiconductor device that functions as a controllable switch, primarily used in high-power applications such as industrial motor control, power modulation, and other applications where electrical power needs to be switched on and off rapidly. It is essentially a type of thyratron, which is a gas-filled tube that can conduct current when triggered by a control signal.
Films about time often explore themes related to time travel, the consequences of time manipulation, the passage of time, and how time affects relationships and personal growth. Here are some popular concepts and examples of films that delve into these themes: ### 1. **Time Travel** - **"Back to the Future" (1985)**: This classic film follows Marty McFly, who travels back to 1955 and must ensure his parents fall in love to secure his own existence.
In fiction, "stasis" refers to a state of equilibrium or balance in a storyline, where characters and their circumstances are relatively unchanging or static. This concept is often used to set the stage for a story, providing a baseline for how things are before a conflict or significant change disrupts the status quo.
"Time" is a British television drama series that premiered on BBC One in June 2021.

The storyline delves into themes of guilt, redemption, and the struggles that come with navigating the criminal justice system.
"Battlefield Earth" is a science fiction novel written by L. Ron Hubbard, published in 1982. The story is set in a post-apocalyptic Earth, which has been under the control of an alien race known as the Psychlos for about a thousand years. The novel follows the character Jonnie Goodboy Tyler, a human who rises up against the oppressive alien regime to free humanity.
Narbacular Drop is a puzzle-platform video game developed by a team of students at DigiPen Institute of Technology in 2005. It is notable for being a precursor to the more widely known game Portal, which was later developed by Valve. In Narbacular Drop, players control a character who has the unique ability to create portals on flat surfaces, allowing them to navigate through a series of puzzles and levels.
"Space" is a science fiction novel written by the author James A. Gardner. It is part of the "Baxter" series, which explores themes of space exploration, the nature of humanity, and the potential futures of technology and society. The narrative often involves complex scientific concepts and philosophical questions, reflecting Gardner's background in both writing and the sciences.
"The Last Continent" is a fantasy novel written by British author Terry Pratchett, published in 1998. It is part of his Discworld series and is the 22nd book in the series. The story follows Rincewind, a inept and cowardly wizard, as he finds himself on a continent that appears to be a parody of Australia, featuring various elements of Australian culture and wildlife.
"The Stars My Destination" is a science fiction novel by Alfred Bester, first published in 1956. The story is set in a future where humans have developed the ability to "jaunte," a form of teleportation that allows individuals to transport themselves instantaneously over distances. The plot follows Gully Foyle, a common man who is stranded in space after his ship is attacked and left to die.
In the Star Trek universe, a transporter is a advanced technology that allows for the instantaneous transfer of matter, particularly people and objects, from one location to another. The most common use of the transporter is to "beam" crew members and equipment from a starship to a planetary surface or between ships, effectively dematerializing them at one location and rematerializing them at another.

Build: Oct 12 2015 14:53:222022-10-14: stopped being able to connect to Ubuntu 22.04. Was trying to do a UART video demo, connected USB, disconnected, connected, disconnected several times on different filming attempts. Was working some of the time, Ubuntu did recognize it, I even saw UART output for sure, but was a bit unstable. But then at one point it just stopped getting recognized by Ubuntu 100% of the time. The board is still being powered by USB, and the previously flashed program still runs, but nothing showed on
sudo dmesg -w at all, and I can't reprogram it!A day later, managed to get tit to connect once more with a different cable, but just once!

Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
