Philosophy of language is a subfield of philosophy that explores the nature, origins, and use of language. It examines fundamental questions about meaning, reference, truth, and the relationship between language and reality. Key topics in this area include: 1. **Meaning**: What does it mean for words or sentences to have meaning?

The philosophy of mind is a branch of philosophy that explores the nature of the mind, consciousness, and their relationship to the physical body, particularly the brain. It addresses fundamental questions related to consciousness, mental states, the nature of thought, perception, emotion, and the relationship between the mind and the body (often referred to as the mind-body problem).

Abstract object theory is a philosophical framework that deals with the nature of abstract objects—entities that do not exist in physical space and do not possess physical properties. Examples of abstract objects include numbers, properties, concepts, sets, and other non-material entities. The theory explores questions such as: 1. **Existence**: What does it mean for an abstract object to exist? Unlike physical objects, abstract objects are often seen as not having a location in space or time.

Ballistics is the science that studies the motion, behavior, and effects of projectiles, most commonly firearms and ammunition. It encompasses several specific areas: 1. **Internal Ballistics**: This involves the processes that occur inside the firearm from the moment the cartridge is fired until the projectile exits the barrel. It examines factors like the combustion of gunpowder, pressure build-up, and the mechanics of the firearm's action.

This is what happens when you apply a DC voltage across a Josephson junction.

It is called "AC effect" because when we apply a DC voltage, it produces an alternating current on the device.

By looking at the Josephson equations, we see that $V(t)=k$ a positive constant, then $\phi$ just increases linearly without bound.

Therefore, from the first equation:we see that the current will just vary sinusoidally between $\pm I_c$.

This meas that we can use a Josephson junction as a perfect voltage to frequency converter.

Wikipedia mentions that this frequency is $484GHz/mV$, so it is very very high, so we are not able to view individual points of the sine curve separately with our instruments.

Also it is likely not going to be very useful for many practical applications in this mode.

An I-V curve can also be seen at: Figure "Electron microscope image of a Josephson junction its I-V curve".

Materials science is an interdisciplinary field that focuses on the properties, performance, processing, and applications of materials. It combines principles from physics, chemistry, engineering, and biology to understand how different materials behave under various conditions and how their internal structures influence their macroscopic properties. Key aspects of materials science include: 1. **Understanding Material Properties**: This involves studying mechanical, thermal, electrical, optical, and magnetic properties of materials. Scientists use these properties to determine how materials will perform in different applications.

If you shine microwave radiation on a Josephson junction, it produces a fixed average voltage that depends only on the frequency of the microwave. TODO how is that done more precisely? How to you produce and inject microwaves into the thing?

It acts therefore as a perfect frequency to voltage converter.

The Wiki page gives the formula: en.wikipedia.org/wiki/Josephson_effect#The_inverse_AC_Josephson_effect You get several sinusoidal harmonics, so the output is not a perfect sine. But the infinite sum of the harmonics has a fixed average voltage value.

And en.wikipedia.org/wiki/Josephson_voltage_standard#Josephson_effect mentions that the effect is independent of the junction material, physical dimension or temperature.

All of the above, compounded with the fact that we are able to generate microwaves with extremely precise frequency with an atomic clock, makes this phenomenon perfect as a Volt standard, the Josephson voltage standard.

TODO understand how/why it works better.

Two equations derived from first principles by Brian Josephson that characterize the device, somewhat like an I-V curve:where:

Note how these equations are not a typical I-V curve, as they are not an instantaneous dependency between voltage and current: the history of the voltage matters! Or in other words, the system has an internal state, represented by the Josephson phase at a given point in time.

To understand them better, it is important to look at some important cases separately:

Maximum current that can flow across a Josephson junction, as can be directly seen from the Josephson equations.

Is a fixed characteristic value of the physical construction of the junction.

Ciro Santilli really likes his sense of humor, always going into "politically incorrect" areas, and often making fun of both dictatorships and the USA. He actually knows a bit about politics. Due to the nature of his humour, many of his earlier videos have been taken down from YouTube apparently, www.ssethtzeentach.com/videos mentions:

The videos are also incredibly packed full of well selected edited-in "memes jokes". He particularly likes very short snippets of gay porn which cannot actually be taken down as porn, even though the obviously are porn excerpts, like the buffed dude blowing a kiss to his tit.

www.youtube.com/watch?v=sw8v5__Ytf4 Heroes of Might and Magic III (2018) is one of the best reviews. Sseth likes to find and make fun of game breaking imbalances, something that Ciro likes due to his Ciro Santilli's self perceived creative personality.

www.youtube.com/watch?v=rOJdDvf-tUs The Sseth Streaming Experience (2019), being a live stream, likely shows more realistically how Seth actually talks in real life.

www.youtube.com/watch?v=yG9g2byXR2c Might and Magic VI (Re)Review is another good video (2021)

Sseth has a certain vaporwave aesthetic, which Ciro also enjoys.

A function $\mathbb{R}\to \mathbb{R}$ defined by the second of the Josephson equations plus initial conditions.

It represents an internal state of the junction.
