Carl Zeiss, Explained: Germany’s Semiconductor Optics Master

Germany-based Carl Zeiss AG is a fascinating company. Fascinating, even if you do not take into account that they make lenses and optics for some of the coolest systems in the world.

When you are etching patterns as wide as a small virus, you have graduated beyond simple lens. Now we refer to them as “optics systems”. These massive multi-component systems are at the very heart of the multi-million dollar photolithography machines that ASML makes. Without them, ASML has no machine to deliver to TSMC, Samsung or Intel.

In this video, we are going to continue with our deep dive into the semiconductor industry’s critical suppliers with a look at one of ASML’s closest partners. The makers of the optics systems that let high-energy UV light etch wafers. And a company with an utterly fascinating history. Carl Zeiss.

Error: The video shows that Zeiss died in 1866. He died in 1888.

Electric Vocabulary

We all know the words around electricity, “charge,” “positive,” “battery”, and more. But where do they come from and what do they really mean? Let the history of these words illuminate the physics of electric phenomena.

Can nanotechnology solve our battery production problem?

From smartphones and laptops to the rapidly growing EV market, we need an incredible amount of lithium-ion batteries to make it all work. Materials like lithium are difficult and time-consuming to mine and extract … and can have a major impact on the environment. Can nanotechnology solve our lithium extraction and mining problem? And maybe even help with solid-state batteries? I talk to Teague Egan from EnergyX about some interesting advancements in nanotech, metal-organic frameworks, and more.

How does a Transformer work – Working Principle electrical engineering

How does a transformer work. In this video we’ll be looking at how a transformer works covering the basics with transformer working animations and explanations to understanding the working principle. We’ll cover how to creating a magnetic field with electricity, Why only Alternating current can only be used in transformers, How a basic transformer works, step up and step down transformers, transformer connections and windings, Three phase transformers, Delta Wye connections.

Basic Electricity – Resistance and Ohm’s law

A tutorial on the basics of electrical resistance, resistors, and Ohm’s law which describes the relationship between voltage, current and resistance. I also show you how to build a simple resistor + LED circuit.

What is an Amp? – Electricity Explained

When you have an electric current it’s useful to be able to measure that current. This is done in amps (often using a multimeter). This video explains what an amp (A) (short for ampere) is, which also involves the coulomb (C). The coulomb is the SI standard unit for electric charge, whereas the amp is the SI standard unit for current.

1A equals 1C per 1s (seconds).

One coulomb is roughly equivalent to 6.24 quintillion(!) electrons carrying a charge. That’s at 1A. Imagine how many electrons pass a certain point when the current is 5000A(!)

What is electricity? – Electricity Explained

What is electricity? How does electricity work? What do electrons do? What is short circuiting? These are all questions answered in this video: A fundamental explainer on what electricity is and how it works.

In following videos we’ll look at voltage, ampere, ohm (resistance) and many more electricity related topics. All of this is to build a foundation of knowledge to serve all the future (and past) videos here on Into The Ordinary.

A couple of choices were made during the production of this video, that can be helpful to know:

I chose to mention the Bohr-model in relation to the orbital model to bring the point across that there is more to atoms than just this. The What Are Atoms? video better explains orbitals than this video does, though.
I intentionally used the word “shells” instead of orbits because it better catches what electrons are in real life, although still a simplification. This video is about electricity, not particle physics.
Power generation, how batteries work, amps, volts, ohms, are all topics I want to address in separate videos.
There will probably be a few more questions about this video, which I will try to address in the comments or in the description, here.

Never directly connect a wire to both holes of a wall socket, and never directly connect a wire to both ends of a battery! This can be dangerous and potentially life-threatening!
