Physics and Chemistry are hard, especially when the subject is so abstract you probably won't be able to even try to understand it. I took a test on Electromagnetism and Stoichiometry recently, so they still linger on my mind.

I had this idea of incorporating real-life, the boring science stuff, into fantasy which is more interesting and forgiving and also includes dragons.

Bonus point if you can point out all the references, sciences or fandoms.

Some Electromagnetism goodness for folks! Hope y'all enjoy! If you'd like a comm too, i'm always open on here, twitter or discord under MamaLuigi2018!

Day 11/40 of productivity

🗓️ TODAY EXAM DAY

I've sorted out my study plan for the upcoming days:

Prepare for the oral exam in electromagnetism

Conduct the laboratory experiment on charge to mass ratio with the Braun tube

Write 2 lab reports 🫠

Study for the lab and statistical analysis exam

The electromagnetism of the body has two homes. The brain and the heart. What we do is we send all the electromagnetism to the brain and out of the heart. That's why the Egyptians said there was a weighing of the heart to dictate who goes to heaven. The electromagnetism once it's drained from the heart forces the pineal gland to open up as lightning. The whole process in metaphysics is actually a temporal paradox. Kundalini kills you to keep you alive. So you're alive yet dead and the reason people say they are alive through Christ. The electromagnetism when absorbed into the brain becomes the reason we can feel our entire body with not just our nervous system but also our mind. When I did the process I would swallow smoke and watch myself pass it out of my body as gas within a few minutes. I literally could control all of my body including digestion with my mind. The entire body is superimposed neurologically inside of the brain. The opening of the pineal gland restarts this metaphorical computer and allows us to hit the reboot button thus breaking out of matter and out of the matrix of existence.

Space is a near-perfect vacuum, but it’s not entirely empty. A small list of matter include :

a few hydrogen atoms here and there (less than one hydrogen atom per cubic meter)

Dark Matter — an enigma that was recently discovered in the 20th century. It doesn’t interact with the normal matter that we’re used to (eg. solid, gas, liquid). We can’t see it since it doesn't interact with light or any electromagnetic radiation. However, it does exist and makes up about 27% of the universe.

Neutrinos — neutral subatomic particles with little mass and no electric charge. They’re from atoms that come together (nuclear fusion) or break apart (nuclear fission)

Electromagnetic radiation and magnetic fields

There are other things that exist in outer space but they’re usually not normal matter and don’t make space very dense at all. It’s okay because space is never truly empty but it can still be very close to empty, making it a far better vacuum than the best ones we can make on earth.

This is not an issue for electromagnetic waves (like light and radio waves) that can travel through space unhindered because they don’t need any medium to propagate.

Sound waves are different since they're mechanical waves, which is just vibrating matter. Hence, they need a medium to travel through to be heard. In space there is no air or medium for sound waves to travel through. This means that no one can hear you scream in space :)

Hans Christian Oersted – Scientist of the Day

On Apr. 21, 1820, according to tradition, the Danish experimental physicist Hans Christian Oersted (Ørsted to the Danes) made a famous accidental discovery in the classroom that launched the age of electromagnetism.

Condor telescope reveals a new world for astrophysicists

"A new telescope called the "Condor Array Telescope" may open up a new world of the very-low-brightness universe for astrophysicists. Four new papers, published back to back in the Monthly Notices of the Royal Astronomical Society (MNRAS) this month, present the first scientific findings based on observations acquired by Condor. The project is a collaborative led by scientists in the Department of Physics and Astronomy at Stony Brook University and the American Museum of Natural History (AMNH)."

"The new "array telescope" uses computers to combine light from several smaller telescopes into the equivalent of one larger telescope and is able to detect and study astronomical features that are too faint to be seen with conventional telescopes."

"In the second paper, Shara and colleagues used Condor to reassess an image of the dwarf nova Z Camelopardalis or "Z Cam" obtained by the Kitt Peak National Observatory 4-meter telescope back in January 2007. The image showed a partial shell of gas surrounding Z Cam, which Shara speculated was emitted by a "new star" recorded by Chinese Imperial astrologers in the year 77 BCE."

This is how electromagnetism works, right?

Day 4/40 of productivity

In less than a week I’ve got the electromagnetism exam coming up.

I still need to start doing exercises because I want to grasp the theory thoroughly first. However, sometimes it takes me a whole day to understand a topic… like today when I’ve spent the entire morning studying magnetic fields in cavities and I’m still not satisfied!

Zero-index metamaterials and the future

In the realm of materials science, electromagnetic (EM) metamaterials have emerged as a revolutionary class of engineered composites capable of manipulating electromagnetic waves in ways never before possible. Unlike their naturally occurring counterparts, EM metamaterials derive their extraordinary properties from their unique structural arrangements, allowing them to exhibit unattainable electromagnetic characteristics in conventional materials. One of the most fascinating characteristics of EM metamaterials lies in the realm of zero-index metamaterials (ZIMs). ZIMs possess the remarkable ability to achieve uniform electromagnetic field distribution over arbitrary shape (Figure 1a). This unique property opens many potential applications, from ultra-compact cloaking devices to arbitrarily shaped waveguides and lenses and photonic crystal surface-emitting lasers (Figure 1b). Despite their immense potential, ZIMs have faced a significant hurdle in their practical implementation. The homogeneity of ZIMs is often limited by the number of unit cells per free-space wavelength. This limitation arises from the low permittivities property of the materials used to construct ZIMs. As a result, ZIMs often require large physical space to achieve their effective electromagnetic properties (Figure 2b).
